Ipilimumab Conveys Long-Term Survival in Pooled Analysis of Metastatic Melanoma Patients

Standardizing the Interpretation of PET Scans: An INR Equivalent

By Caroline Helwick

n the treatment of metastatic or locally advanced unresectable melanoma, the anti–CTLA-4 monoclonal antibody ipilimumab (Yervoy) conveys long-term survival benefits, with some patients alive out to 10 years, according to the largest survival analysis of the immunomodulating agent, presented at the 2013 European Cancer Congress by Stephen F. Hodi, MD, Director of the Melanoma Center at Dana-Farber Cancer Institute, Boston.1 “The observed ipilimumab overall survival curve demonstrated greater durability of survival, relative to historical data in the pre-BRAF inhibitor era,” he said. “This analysis adds to the evidence supporting a durable, long-term survival effect of ipilimumab in patients with advanced melanoma.”

Study Details The pooled analysis included 1,861 patients from 12 prospective and retrospective trials, and an addi-

tional 2,985 patients who were treated with ipilimumab outside of a clinical trial in the expanded access program. The findings are the most precise estimate yet of the benefit of ipilimumab, Dr. Hodi said. The analysis of the 1,861 patients in trial regisStephen F. Hodi, MD tries found median overall survival to be 11.4 months, with 254 patients (22%) alive 3 years after initiating treatment with ipilimumab. Median overall survival for the whole population, including the 2,985 patients in the expanded access program, was 9.5 months, with 3-year survival in 21% of patients. Dr. Hodi attributed the slightly shorter survival time in this group to limited data and to the possibility that this was a sicker population. continued on page 4

ince its introduction, the positron-emission tomography (PET) scan has shown great potential to improve our ability to care for patients with lymphoma. By demonstrating which masses seen on a computed tomography (CT) scan represent viable tumor, and by identifying viable tumor in places that were not seen on the CT scan, PET scans offer a major advance. However, PET scanning is complicated. A wide variety of factors—including time from injection to scan, the patient’s blood glucose, the method of calculating the area of interest for standardized uptake value (SUV) calculations, the method of interpretation (ie, visual/Gestalt interpretation vs basing the continued on page 52

n September, the Institute of Medicine (IOM) of the National Academies issued its report, Delivering High-Quality Cancer Care: Charting a New Course for a System in Crisis,1 published more than a decade after its first study on the quality of cancer care in the United States. The authors of the new publication acknowledged that the “barriers to achieving excellent care for all cancer patients remain daunting,” and declared that the current cancer delivery system is in crisis.

New Challenges

The study authors agreed that much has been accomplished in the 14 years since the IOM’s previous report, Ensuring Quality Cancer Care,2 including increased screening, more precise diagnostics and surgical techniques, and the development of targeted molecular therapy. However, those advances, plus an aging population, rising cancer incidence, projected workforce shortages and soaring medical costs are also helping drive the current crisis—and potentially an even more calamitous one if nothing is done. Cancer care needs to be “The extreme chaltailored to every patient’s needs, lenges that we face now are different from and communication is central the ones we faced in to that effort. the late 1990s,” said —Patricia A.

Strong Showing for Ado-Trastuzumab Emtansine in Advanced HER2-Positive Heavily Pretreated Breast Cancer By Alice Goodman

R

esults of the phase III TH3RESA trial show that the antibodyconjugate ado-trastuzumab emtansine (Kadcyla), formerly known as T-DM1, extends progression-free survival in women with advanced HER2-positive breast cancer that progressed on two or more previous HER2-directed therapies including trastuzumab (Herceptin) and lapatinib (Tykerb). The findings were presented at the European Cancer Congress 2013 in Amsterdam.1

Building on EMILIA Trial These results build on those of the EMILIA trial, which showed that adotrastuzumab emtansine extended progression-free survival compared with capecitabine/lapatinib in HER2-positive advanced breast cancer in women previously treated with trastuzumab and a taxane. Patients in TH3RESA were more heavily pretreated than those in EMILIA. “In TH3RESA, [ado-trastuzumab emtansine] demonstrated improved

the lead author of the late-breaking presentation, Hans Wildiers, MD, PhD, of University Hospitals Leuven in Leuven, Belgium. He added that ado-trastuzumab emtansine should become the new standard of care for second-line treatment. “Once HER2-positive breast cancer recurs and metastasizes, there are few treatment options that show any clear benefit for women who have probably undergone several previous treatments for the disease. These results confirm and extend the usefulness of [adotrastuzumab emtansine] for the treatment of women with advanced HER2positive disease. This is good news for these women,” said Cornelis van de Velde, MD, current President of the European Cancer Organization (ECCO) and moderator of a press conference where these findings were discussed. Ado-trastuzumab emtansine is an antibody-drug conjugate currently FDA-approved for metastatic breast cancer previously treated with a taxane and trastuzumab.

EXPERT POINT OF VIEW

F

ormal discussant Clifford Hudis, MD, ASCO President and Chief of the Breast Cancer Service at Memorial Sloan-Kettering Cancer Center in New York, commented that the findings were not surprising. “The results of TH3RESA nicely reflect the EMILIA trial and are consistent with those of anti-HER2 therapies. These antibody-based therapies have revolutionized the treatment of a subset of breast cancer patients.” Clifford Hudis, MD He said that ado-trastuzumab emtansine should be considered in HER2-positive disease as second-, third- or fourth-line treatment. Remaining issues are the optimal sequencing of HER2-directed therapies and the best role for ado-trastuzumab emtansine, he added. He also said that there might be biomarkers (not yet identified) for subsets of patients with a preferential response to ado-trastuzumab emtansine. n Disclosure: Dr. Hudis reported no potential conflicts of interest.

Wildiers said this difference was both statistically and clinically significant. A subgroup analysis showed a con-

safety and efficacy compared with the physician’s choice of chemotherapy. [Ado-trastuzumab emtansine] achieved a significant improvement in progression-free survival, and the effect was clear and consistent across subgroups. These data affirm the results of EMILIA, demonstrating a consistent progression-free survival benefit of [ado-trastuzumab emtansine] in patients with previously treated HER2positive advanced breast cancer,” said

The study included 602 patients with advanced breast cancer previously treated with at least two previous HER2-directed therapies. Patients were randomly assigned in a 2:1 ratio to adotrastuzumab emtansine or physician’s choice of chemotherapy (83% received trastuzumab-based regimens and 17% received chemotherapy). Treatment was continued until disease progression, when patients could remain on or cross over to ado-trastuzumab emtansine. Final progression-free survival results were as follows: median progression-free survival of 6.2 months for the ado-trastuzumab emtansine–treated group vs 3.3 months in the control arm, a highly significant difference in favor of ado-trastuzumab emtansine, nearly doubling progression-free survival compared with controls (P < .0001).

sistent near-doubling of progressionfree survival with ado-trastuzumab emtansine regardless of age, geographic area, race, performance status, tumor characteristics, and visceral disease. The first interim analysis of overall survival showed median survival of 14.9 months in the control arm; median overall survival was not yet reached in the ado-trastuzumab emtansine arm at the time of analysis. Although this suggests that there may be a survival advantage for ado-trastuzumab emtansine, long-term confirmation is needed. Final survival results are expected in 2015.

Reassuring Safety Profile The safety of ado-trastuzumab emtansine was reassuring and similar to what was reported in the EMILIA trial. Adverse events of grade 3 or higher were more frequent in the control arm:

43.5% vs 32.3% in the ado-trastuzumab emtansine arm. Adverse events of any grade were reported by 94% of those who received ado-trastuzumab emtansine vs 89% in the control arm. Adverse events leading to discontinuation of therapy occurred in 6.7% of the ado-trastuzumab emtansine group vs 10.9% of controls. The rate of cardiac events was low in both arms: left-ventricular ejection fraction < 50 was reported in 1.5% and 1.1%, respectively. Lower rates of diarrhea, neutropenia, and febrile neutropenia were reported in the ado-trastuzumab emtansine arm, but a slight increase was observed in severe thrombocytopenia (4.4% vs 1.8%, respectively) and hemorrhage (2.2% vs 0.5%). According to Dr. Wildiers, an ongoing phase III trial is evaluating use of ado-trastuzumab emtansine as first-line therapy in advanced HER2positive breast cancer, and results are expected next year. The benefit of treatment with ado-trastuzumab emtansine after disease progression will also be studied. n Disclosure: Dr. Wildiers has received lecture fees from Roche. Dr. van de Velde reported no potential conflicts of interest.

Cediranib Achieves ‘Groundbreaking’ Results in Relapsed Ovarian Cancer By Alice Goodman

T

he investigational oral vascular endothelial growth factor (VEGF) inhibitor cediranib extended progression-free survival when given with platinum-based chemotherapy and improved overall survival when given as maintenance therapy in patients with recurrent ovarian cancer. Experts are hopeful that these encouraging results of the ICON6 trial will trigger a resurrection for development of this agent. Cediranib plus platinum-based chemotherapy followed by maintenance cediranib prolonged progression-free survival by 3.2 months and overall survival by 2.7 months. “These are groundbreaking data. This is the first trial to demonstrate a significant improvement in progression-free survival and overall survival with an oral VEGF tyrosine kinase inhibitor in ovarian cancer,” stated lead

In both groups, the benefit of the drug appeared to plateau after about 3 years. Beyond 7 years, no deaths were reported, and median 7-year overall survival was 17%. The longest recorded survival was 9.9 years. This survival plateau was observed regardless of dose (3 or 10 mg/kg), previous treatment, or the continued use of ipilimumab as maintenance, he said.

Study Details ICON6 is the first trial to investigate an oral VEGF receptor tyrosine kinase inhibitor combined with chemotherapy and given as maintenance in recurrent ovarian cancer. The study had a complex design. Ovarian cancer patients (N = 456) with a relapse-free interval greater than 6 months following first-line chemotherapy were randomly assigned to platinum-based chemotherapy plus placebo followed by placebo maintenance, chemotherapy plus cediranib followed by placebo maintenance, or chemotherapy plus cediranib followed by cediranib maintenance. Treatment was continued until disease progression. continued on page 5

“Around the inflexion point of 3 years, there seems to be a flattening of the tail of the curve,” Dr. Hodi noted. “Going forward up to 10 years, with lots of censoring, we see a group of patients maintaining a survival advantage long term.”

eca had discontinued development of cediranib after disappointing phase III results in colorectal cancer, lung cancer, and glioblastoma. The company’s cediranib team was not at the meeting, but a spokesperson for the company subsequently indicated that the results of this study would be reviewed in more detail and a decision about the possible resurrection of cediranib would be made. Thus, it remains unclear as to whether cediranib will re-enter development for U.S. Food and Drug Administration (FDA) approval in ovarian cancer. “These results are important for women with recurrent ovarian cancer. These patients have few treatment options available that can make a significant difference to progression and overall survival,” said European CanCer Organisation (ECCO) President Cornelis van der Velde, MD, Profes-

commented on the findings. “This pooled analysis clearly demonstrates that ipilimumab can lead to long-lasting tumor control in metastatic melanoma patients. With a response rate

of only 10% to 15%, one can achieve more than 3 to 10 years of survival in 17% to 25% of patients who have received only a few doses of ipilimumab. Thus, patients apparently can keep residual tumors under control for a long time when the immune system is properly ‘reset,’ and the concept of ‘clinical cures’ becomes a reality.” Dr. Eggermont and Dr. Hodi agreed that when novel antibodies targeting the programmed death 1 protein and its ligand (anti–PD-1/ PD-L1) become available, metastatic melanoma could become a chronic illness and potentially “curable” in some patients. “A few years ago, I could never imagine using the ‘C’ word, or see patients living long term,” Dr. Hodi commented. “What we are showing

is a great paradigm shift. At least we are turning this disease into a chronic illness. Possibly, in a subset [of patients], we are beginning to consider that this could be a cure. I remain optimistically conservative on that point, but we are headed in the right direction.” n

Median progression-free survival was 8.7 months in the chemotherapy/ placebo comparator arm (no cediranib) and 11.1 months in the cediranib-maintenance arm (P = .00001). A restricted means analysis showed a 3.2-month difference favoring cediranib (9.4 vs 12.5 months). Dr. Ledermann clarified the rationale for a restricted means analysis of study results. “The hazard ratio is not constant over time. Although you can undertake a standard log-rank analysis, the restricted means analysis takes into account the changing proportionality of the two curves over time,” he explained. A secondary restrictive means analysis compared the arm receiving chemotherapy/cediranib plus placebo maintenace vs the arm receiving chemotherapy/cedi-

ranib plus cediranib maintenance. This analysis showed a 1.3-month difference in progression-free survival favoring cediranib maintenance. The log-rank analysis showed a trend toward improved diseasefree survival, with some benefit from adding cediranib to chemotherapy and a greater benefit from continuing cediranib as maintenance. “The study provides strong evidence that cediranib has an effect by itself on progression-free survival both during and after chemotherapy,” Dr. Ledermann said.

Other Findings Median overall survival was 20.3 months in the chemotherapy-alone arm and 26.3 months in the cediranib maintenance arm (P = .042). In a restricted means analysis, overall survival was 17.6 and 20.3 months, respectively.

Cediranib in Ovarian Cancer ■■ Cediranib, an oral VEGF inhibitor, prolonged survival in patients who had relapsed after first-line chemotherapy for ovarian cancer.

■■ These encouraging results were achieved with cediranib given concurrently with platinum-based chemotherapy and then as maintenance therapy.

■■ Phase III studies of cediranib in other cancer types have been disappointing, leading to the decision to stop development; the manufacturer may be reconsidering that decision after these results.

EXPERT POINT OF VIEW

P

ress conference moderator Cora N. Sternberg, MD, Chief of Medical Oncology at San Camillo and Forlanini Hospitals, Rome, called the 2- to 3-month improvement in overall survival “worthwhile, and clinically meaningful.” She said this should be viewed in the context of manageable toxicity. “Cediranib is a tyrosine kinase inhibitor that has a different mechanism of action from bevacizumab [Avastin]. I can envision using cediranib in a patient who becomes resistant to bevacizumab,” she comCora N. Sternberg, MD mented. “Cediranib is not a licensed drug, and won’t be available unless the manufacturer decides to continue with its development. With a positive study like this, AstraZeneca may rethink the situation,” she said. n Disclosure: Dr. Sternberg reported no potential conflicts of interest.

Adverse events that were significantly more frequent in the maintenance arm were hypertension, diarrhea, hypothyroidism, hoarseness, hemorrhage, proteinuria, and fatigue. Most of these were manageable with dose reductions or interruptions in therapy. The addition of cediranib did not compromise the ability to undergo chemotherapy; around 80% of patients completed the full six cycles, and most patients stayed on maintenance cediranib until disease progression, Dr. Ledermann told listeners.

“These results suggest cediranib will have a role in the treatment of recurrent ovarian cancer,” Dr. Ledermann said. n

Disclosure: Dr. Ledermann received grant support from AstraZeneca for this trial. Most of the funding was from Cancer Research UK.

bevacizumab (Avastin), significantly improved progression-free survival in recurrent platinum-resistant and partially platinum-sensitive ovarian cancer in the phase III TRINOVA-1 trial. The addition of trebananib to paclitaxel prolonged the time to disease progression or death by 52% compared with paclitaxel plus placebo (P < .001),

said Bradley J. Monk, MD, FACOG, FACS, of Creighton University School of Medicine and The University of Arizona Cancer Center, Phoenix, at the recent European Cancer Congress in Amsterdam.1 “Angiogenesis is a valid target in ovarian cancer. A long list of studies shows that antiangiogenesis agents can prolong progression-free survival in the platinum-sensitive space. However, no increase in overall survival has been seen with this approach,” he said. Anti–vascular endothelial growth

factor (VEGF) therapy with bevacizumab and pazopanib (Votrient) “creates a constellation of adverse events,” Dr. Monk continued. “The idea of the TRINOVA series of clinical trials is to target non-VEGF angiogenesis factors—angiopoeitin-1 and angiopoetin-2—with trebananib and determine efficacy and side effects with this non-VEGF approach,” he explained. Previous studies had suggested that inhibition of angiopoietin-1 and -2 with trebananib can delay progression of tumors or shrink them, he noted.

TRINOVA-1: Trebananib in Ovarian Cancer ■■ A non–VEGF inhibitor approach extended progression-free survival in

patients with recurrent epithelial ovarian cancer, and this benefit was seen in all subgroups.

■■ Trebananib, an inhibitor of angiopoeitin-1 and -2, will be studied further in ovarian cancer.

■■ This novel agent does not cause the adverse events associated with VEGF inhibition.

Study Design and Results The phase III TRINOVA-1 trial enrolled 919 women with recurrent epithelial ovararian cancer and randomly assigned them to treatment with trebananib at 15 mg/kg IV every 4 weeks plus weekly paclitaxel or placebo plus weekly paclitaxel. Treatment continued until disease progression, toxicity, or withdrawal of consent. Patients were stratified according to progression-free interval, measurable disease, and geographic region. At baseline, patients had received up to three prior cytotoxic regimens and had a progression-free interval of less than 12 months from the last treatment. About 40% of patients experienced treatment failure on one prior regimen, 40% on two, and 20% on three. “This was a rigorous, closely audited clinical trial, with 919 patients from 179 sites in 32 countries.

Two Trials Explore the Evolving Role of Bevacizumab in Ovarian Cancer By Alice Goodman

T

he optimal use of bevacizumab (Avastin) in ovarian cancer appears to be in high-risk subgroups and in patients with platinum-resistant ovarian cancer, according to results of two phase III trials presented at the 2013 European Cancer Congress (ECC) in Amsterdam. AURELIA investigated the safety and efficacy of bevacizumab in a range of chemotherapies in patients with platinum-resistant ovarian cancer,1 and ICON7 looked at the effect of bevacizumab on survival in women with newly diagnosed ovarian cancer.2

AURELIA AURELIA met its primary endpoint, significantly improving progression-free survival from 3.4 to 6.7 months with the additional of bevacizumab in patients with platinum-resistant ovarian cancer. Also, bevacizumab improved median overall survival from 13.3 to 16.6 months compared with chemotherapy alone (including paclitaxel, topotecan, and liposomal doxorubicin), but the survival benefit did not reach statistical significance. “No single agent has shown superiority to weekly paclitaxel, topotecan, or liposomal doxorubicin. Median survival in

survival and interim overall survival results, and next year, the final overall survival,” Dr. Monk told listeners. At a median follow-up of 10 months, median progression-free survival was 7.2 months in the trebananib group and 5.4 months for placebo (hazard ratio = 0.66, 95% confidence interval = 0.56–0.76, P < .001). A prespecified subgroup analysis found that trebananib improved progression-free survival in all subgroups. Overall response rate was 38% with trebananib vs 30% with placebo. Dr. Monk noted that most responses were partial.

Adverse Events The rate of adverse events of any grade was similar between the two treatment arms: 96% for trebananib and 97% for placebo, suggesting that trebananib does not increase toxicity when added to paclitaxel. The major toxicity of trebananib was edema, which occurred in 57% vs 26% of the two arms, respectively. Very few grade

platinum-resistant ovarian cancer is typically around 12 months,” said lead author Petronella O. ­Witteveen, MD, PhD, of University Medical Centre, Utrecht, The Netherlands. “AURELIA is the first phase III study to evaluate the addition of bevacizumab in platinum-resistant disease [defined as progression within 6 months of last platinum-containing therapy],” she added. The study randomly assigned 361 patients to bevacizumab plus investigator’s choice of chemotherapy vs chemotherapy alone and patients were treated until progression, unacceptable toxicity, or consent withdrawal. At progression, patients in the chemotherapy arm were allowed to cross over to bevacizumab

monotherapy, but bevacizumab was not continued in the bevacizumab-plus-chemotherapy arm after progression. The two arms were well balanced for demographic and disease characteristics. About 25% had a progression-free interval of less than 3 months. “At baseline, these were very sick patients,” Dr. Witteveen said. Bevacizumab almost doubled progression-free survival from a median of 3.4 months to 6.7 months (P < .001). Median overall survival was 13.3 months with chemotherapy only vs 16.6 months with bevacizumab, a difference that was not statistically s­ ignificant. The study was limited because it was not powered to detect a statistically sig-

Bevacizumab for High-Risk Ovarian Cancer ■■ The phase III AURELIA trial found a clinically meaningful but not statistically significant 3month survival difference when bevacizumab was given to high-risk patients with platinum-resistant ovarian cancer.

■■ An exploratory analysis suggested that weekly paclitaxel is a better partner for bevacizumab than liposomal doxorubicin or topotecan, but this remains to be established.

■■ The phase III ICON7 trial showed that bevacizumab improved survival by 4.8 months in poor-prognosis patients.

3 or higher adverse events were reported with trebananib. “The adverse event profile of antiangiopoietin therapy is not the same as with VEGF inhibitors,” Dr. Monk said. No increase in VEGF-associated side effects (ie, hypertension, proteinuria, wound healing complica-

EXPERT POINT OF VIEW

ormal discussant of the TRINOVA-1 presentation, Antonio Casado, MD, Hospital Universitario San Carlos, Madrid, said that the study showed a clinically meaningful benefit with the addition of trebananib in this pretreated group of patients with recurrent epithelial ovarian cancer. Also, the drug had a good side-effect profile. Moving forward, if future trials of trebananib support these results and the drug is approved, the question will be how to combine it and sequence it with currently available therapies, he noted. “Weekly paclitaxel and trebananib could be an option in patients who show disease progression within 12 months after one to three previous lines of therapy,” Dr. Casado said. n Disclosure: Dr. Casado reported no potential conflicts of interest.

nificant difference in overall survival, and also due to the planned nonrandomized crossover to bevacizumab in the chemotherapy arm, Dr. Witteveen noted. Seventy-two patients did cross over to bevacizumab and received a median of 4.5 cycles of ­therapy.

Subgroup Analysis In an exploratory subgroup analysis of overall survival, weekly paclitaxel was the winner when combined with bevacizumab. In the cohort treated with liposomal doxorubicin, median overall survival was 13.7 months in those randomized to bevacizumab plus chemotherapy vs 14.1 months with chemotherapy only. For the topotecan-treated cohort, median progression-free survival was 13.8 vs 13.3 months, respectively. However, in the weekly paclitaxel cohort, median overall survival was 22.4 months for bevacizumab vs 13.2 months in controls, representing a 35% relative improvement favoring bevacizumab. “The effect of weekly paclitaxel should be considered exploratory and requires prospective validation,” Dr. Witteveen said. continued on page 11

TRINOVA-1 incorporated patientreported outcomes using three different quality-of-life questionnaires: Functional Assessment of Cancer Therapy– Ovarian (FACT-O), the FACT ovarian cancer subscale (OCS), and the EuroQol Group’s EQ-5D. On these measures, no quality-of-life differences were reported between the two treatment arms. Amgen is moving forward with a full development program for trebananib, Dr. Monk noted. n

Important Safety Information Boxed WARNING: Embryo-Fetal Toxicity

• Exposure to PERJETA can result in embryo-fetal death and birth defects. Studies in animals have resulted in oligohydramnios, delayed renal development, and death. Advise patients of these risks and the need for effective contraception —Verify pregnancy status prior to the initiation of PERJETA. Advise patients of the risks of embryo-fetal death and birth defects and the need for contraception during and after treatment. Advise patients to contact their healthcare provider immediately if they suspect they may be pregnant —If PERJETA is used during pregnancy or if a patient becomes pregnant while being treated with PERJETA, immediately report exposure to the Genentech Adverse Event Line at 1-888-835-2555. Encourage women who may be exposed during pregnancy to enroll in the MotHER Pregnancy Registry by contacting 1-800-690-6720 —Monitor patients who become pregnant during PERJETA therapy for oligohydramnios. If oligohydramnios occurs, perform fetal testing that is appropriate for gestational age and consistent with community standards of care. The efficacy of intravenous hydration in the management of oligohydramnios due to PERJETA exposure is not known

Additional Important Safety Information Left Ventricular Dysfunction

• In the randomized trial, PERJETA in combination with Herceptin and docetaxel was not associated with increases in the incidence of symptomatic left ventricular systolic dysfunction (LVSD) or decreases in left ventricular ejection fraction (LVEF) compared with placebo in combination with Herceptin and docetaxel

• Left ventricular dysfunction occurred in 4.4% of patients in the PERJETA-treated group and 8.3% of patients in the placebo-treated group • Symptomatic LVSD (congestive heart failure) occurred in 1.0% of patients in the PERJETA-treated group and 1.8% of patients in the placebo-treated group • Patients who have received prior anthracyclines or prior radiotherapy to the chest area may be at higher risk of decreased LVEF • Assess LVEF prior to initiation of PERJETA and at regular intervals (eg, every 3 months) during treatment to ensure that LVEF is within your institution’s normal limits • If LVEF is <40%, or is 40% to 45% with a 10% or greater absolute decrease below the pretreatment value, withhold PERJETA and Herceptin and repeat LVEF assessment within approximately 3 weeks. Discontinue PERJETA and Herceptin if the LVEF has not improved or has declined further, unless benefits for the individual patient outweigh the risks

Infusion-Associated Reactions, Hypersensitivity Reactions/Anaphylaxis

• PERJETA has been associated with infusion and hypersensitivity reactions • On the first day, when only PERJETA was administered, the overall frequency of infusion reactions was 13.0% in the PERJETA-treated group and 9.8% in the placebo-treated group, with the majority being mild to moderate. The most common infusion reactions (≥1.0%) were pyrexia, chills, fatigue, headache, asthenia, hypersensitivity, and vomiting • During the second cycle, when all drugs were administered on the same day, the most common infusion reactions in the PERJETA-treated group (≥1.0%) were fatigue, dysgeusia, hypersensitivity, myalgia, and vomiting • In the randomized trial, the overall frequency of hypersensitivity reactions/ anaphylaxis was 10.8% in the PERJETA-treated group and 9.1% in the placebotreated group

PERJETA® (pertuzumab) INJECTION, FOR INTRAVENOUS USE INITIAL U.S. APPROVAL: 2012 WARNING: EMBRYO-FETAL TOXICITY See full prescribing information for complete boxed warning. Exposure to PERJETA can result in embryo-fetal death and birth defects. Studies in animals have resulted in oligohydramnios, delayed renal development, and death. Advise patients of these risks and the need for effective contraception. (5.1, 8.1, 8.6)

1 INDICATIONS AND USAGE PERJETA is indicated for use in combination with trastuzumab and docetaxel for the treatment of patients with HER2-positive metastatic breast cancer who have not received prior anti-HER2 therapy or chemotherapy for metastatic disease. 4 CONTRAINDICATIONS None. 5 WARNINGS AND PRECAUTIONS 5.1 Embryo-Fetal Toxicity PERJETA can cause fetal harm when administered to a pregnant woman. Treatment of pregnant cynomolgus monkeys with pertuzumab resulted in oligohydramnios, delayed fetal kidney development, and embryo-fetal death. If PERJETA is administered during pregnancy, or if the patient becomes pregnant while receiving this drug, the patient should be apprised of the potential hazard to a fetus [see Use in Specific Populations (8.1)]. Verify pregnancy status prior to the initiation of PERJETA. Advise patients of the risks of embryo-fetal death and birth defects and the need for contraception during and after treatment. Advise patients to contact their healthcare provider immediately if they suspect they may be pregnant. If PERJETA is administered during pregnancy or if a patient becomes pregnant while receiving PERJETA, immediately report exposure to the Genentech Adverse Event Line at 1-888-835-2555. Encourage women who may be exposed during pregnancy to enroll in the MotHER Pregnancy Registry by contacting 1-800-690-6720 [see Patient Counseling Information (17)]. Monitor patients who become pregnant during PERJETA therapy for oligohydramnios. If oligohydramnios occurs, perform fetal testing that is appropriate for gestational age and consistent with community standards of care. The efficacy of intravenous hydration in the management of oligohydramnios due to PERJETA exposure is not known. 5.2 Left Ventricular Dysfunction Decreases in LVEF have been reported with drugs that block HER2 activity, including PERJETA. In the randomized trial, PERJETA in combination with trastuzumab and docetaxel was not associated with increases in the incidence of symptomatic left ventricular systolic dysfunction (LVSD) or decreases in LVEF compared with placebo in combination with trastuzumab and docetaxel [see Clinical Studies (14.1)]. Left ventricular dysfunction occurred in 4.4% of patients in the PERJETA-treated group and 8.3% of patients in the placebo-treated group. Symptomatic left ventricular systolic dysfunction (congestive heart failure) occurred in 1.0% of patients in the PERJETA-treated group and 1.8% of patients in the placebotreated group [see Adverse Reactions (6.1)]. Patients who have received prior anthracyclines or prior radiotherapy to the chest area may be at higher risk of decreased LVEF. PERJETA has not been studied in patients with a pretreatment LVEF value of ≤ 50%, a prior history of CHF, decreases in LVEF to < 50% during prior trastuzumab therapy, or conditions that could impair left ventricular function such as uncontrolled hypertension, recent myocardial infarction, serious cardiac arrhythmia requiring treatment or a cumulative prior anthracycline exposure to > 360 mg/m2 of doxorubicin or its equivalent. Assess LVEF prior to initiation of PERJETA and at regular intervals (e.g., every three months) during treatment to ensure that LVEF is within the institution’s normal limits. If LVEF is < 40%, or is 40% to 45% with a 10% or greater absolute decrease below the pretreatment value, withhold PERJETA and trastuzumab and repeat LVEF assessment within approximately 3 weeks. Discontinue PERJETA and trastuzumab if the LVEF has not improved or has declined further, unless the benefits for the individual patient outweigh the risks [see Dosage and Administration (2.2)]. 5.3 Infusion-Associated Reactions, Hypersensitivity Reactions/ Anaphylaxis PERJETA has been associated with infusion and hypersensitivity reactions [see Adverse Reactions (6.1)]. An infusion reaction was defined in the randomized trial as any event described as hypersensitivity, anaphylactic reaction, acute infusion reaction or cytokine release syndrome occurring during an infusion or on the same day as the infusion. The initial dose of PERJETA was given the day before trastuzumab and docetaxel to allow for the examination of PERJETA-associated reactions. On the first day, when only PERJETA was administered, the overall frequency of infusion reactions was 13.0% in the PERJETA-treated group and 9.8% in the placebo-treated group. Less than 1% were grade 3 or 4. The most common infusion reactions (≥ 1.0%) were pyrexia, chills, fatigue, headache, asthenia, hypersensitivity, and vomiting. During the second cycle when all drugs were administered on the same day, the most common infusion reactions in the PERJETAtreated group (≥ 1.0%) were fatigue, dysgeusia, hypersensitivity, myalgia, and vomiting. In the randomized trial, the overall frequency of hypersensitivity/ anaphylaxis reactions was 10.8% in the PERJETA-treated group and 9.1% in the placebo-treated group. The incidence of Grade 3 – 4 hypersensitivity/anaphylaxis reactions was 2% in the PERJETAtreated group and 2.5% in the placebo-treated group according to National Cancer Institute – Common Terminology Criteria for Adverse Events (NCI - CTCAE) (version 3). Overall, 4 patients in PERJETA-treated group and 2 patients in the placebo-treated group experienced anaphylaxis. Observe patients closely for 60 minutes after the first infusion and for 30 minutes after subsequent infusions of PERJETA. If a significant infusion-associated reaction occurs, slow or interrupt the infusion and administer appropriate medical therapies. Monitor patients carefully until complete resolution of signs and symptoms. Consider permanent discontinuation in patients with severe infusion reactions [see Dosage and Administration (2.2)]. 5.4 HER2 Testing Detection of HER2 protein overexpression is necessary for selection of patients appropriate for PERJETA therapy because these are the only patients studied and for whom benefit has been shown [see Indications and Usage (1) and Clinical Studies (14)]. In the randomized trial, patients with breast cancer were required to have evidence of HER2 overexpression defined as 3+ IHC by

Dako Herceptest™ or FISH amplification ratio ≥ 2.0 by Dako HER2 FISH PharmDx™ test kit. Only limited data were available for patients whose breast cancer was positive by FISH but did not demonstrate protein overexpression by IHC. Assessment of HER2 status should be performed by laboratories with demonstrated proficiency in the specific technology being utilized. Improper assay performance, including use of suboptimally fixed tissue, failure to utilize specified reagents, deviation from specific assay instructions, and failure to include appropriate controls for assay validation, can lead to unreliable results. 6 ADVERSE REACTIONS The following adverse reactions are discussed in greater detail in other sections of the label: • Embryo-Fetal Toxicity [see Warnings and Precautions (5.1)] • Left Ventricular Dysfunction [see Warnings and Precautions (5.2)] • Infusion-Associated Reactions, Hypersensitivity Reactions/ Anaphylaxis [see Warnings and Precautions (5.3)] 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice. In clinical trials, PERJETA has been evaluated in more than 1400 patients with various malignancies and treatment with PERJETA was predominantly in combination with other anti-neoplastic agents. The adverse reactions described in Table 1 were identified in 804 patients with HER2-positive metastatic breast cancer treated in the randomized trial. Patients were randomized to receive either PERJETA in combination with trastuzumab and docetaxel or placebo in combination with trastuzumab and docetaxel. The median duration of study treatment was 18.1 months for patients in the PERJETA-treated group and 11.8 months for patients in the placebo-treated group. No dose adjustment was permitted for PERJETA or trastuzumab. The rates of adverse events resulting in permanent discontinuation of all study therapy were 6.1% for patients in the PERJETA-treated group and 5.3% for patients in the placebo-treated group. Adverse events led to discontinuation of docetaxel alone in 23.6% of patients in the PERJETA-treated group and 23.2% of patients in the placebo-treated group. Table 1 reports the adverse reactions that occurred in at least 10% of patients on the PERJETA-treated group. The most common adverse reactions (> 30%) seen with PERJETA in combination with trastuzumab and docetaxel were diarrhea, alopecia, neutropenia, nausea, fatigue, rash, and peripheral neuropathy. The most common NCI - CTCAE (version 3) Grade 3 – 4 adverse reactions (> 2%) were neutropenia, febrile neutropenia, leukopenia, diarrhea, peripheral neuropathy, anemia, asthenia, and fatigue. An increased incidence of febrile neutropenia was observed for Asian patients in both treatment arms compared with patients of other races and from other geographic regions. Among Asian patients, the incidence of febrile neutropenia was higher in the pertuzumab-treated group (26%) compared with the placebo-treated group (12%).

*In this table this denotes an adverse reaction that has been reported in association with a fatal outcome The following clinically relevant adverse reactions were reported in < 10% of patients in the PERJETA-treated group: Skin and subcutaneous tissue disorders: Paronychia (7.1% in the

PERJETA-treated group vs. 3.5% in the placebo-treated group) Respiratory, thoracic and mediastinal disorders: Pleural effusion (5.2% in the PERJETA-treated group vs. 5.8% in the placebotreated group) Cardiac disorders: Left ventricular dysfunction (4.4% in the PERJETA-treated group vs. 8.3% in the placebo-treated group) including symptomatic left ventricular systolic dysfunction (CHF) (1.0% in the PERJETA-treated group vs. 1.8% in the placebotreated group) Immune system disorders: Hypersensitivity (10.1% in the PERJETA-treated group vs. 8.6% in placebo-treated group) Adverse Reactions Reported in Patients Receiving PERJETA and Trastuzumab after Discontinuation of Docetaxel In the randomized trial, adverse reactions were reported less frequently after discontinuation of docetaxel treatment. All adverse reactions in the PERJETA and trastuzumab treatment group occurred in < 10% of patients with the exception of diarrhea (19.1%), upper respiratory tract infection (12.8%), rash (11.7%), headache (11.4%), and fatigue (11.1%). 6.2 Immunogenicity As with all therapeutic proteins, there is the potential for an immune response to PERJETA. Patients in the randomized trial were tested at multiple time-points for antibodies to PERJETA. Approximately 2.8% (11/386) of patients in the PERJETA-treated group and 6.2% (23/372) of patients in the placebo-treated group tested positive for anti-PERJETA antibodies. Of these 34 patients, none experienced anaphylactic/ hypersensitivity reactions that were clearly related to the antitherapeutic antibodies (ATA). The presence of pertuzumab in patient serum at the levels expected at the time of ATA sampling can interfere with the ability of this assay to detect anti-pertuzumab antibodies. In addition, the assay may be detecting antibodies to trastuzumab. As a result, data may not accurately reflect the true incidence of anti-pertuzumab antibody development. Immunogenicity data are highly dependent on the sensitivity and specificity of the test methods used. Additionally, the observed incidence of a positive result in a test method may be influenced by several factors, including sample handling, timing of sample collection, drug interference, concomitant medication, and the underlying disease. For these reasons, comparison of the incidence of antibodies to PERJETA with the incidence of antibodies to other products may be misleading.

If PERJETA is administered during pregnancy or if a patient becomes pregnant while receiving PERJETA, immediately report exposure to the Genentech Adverse Event Line at 1-888-835-2555. Encourage women who may be exposed during pregnancy to enroll in the MotHER Pregnancy Registry by contacting 1-800-690-6720 [see Patient Counseling Information (17)]. 8.7 Renal Impairment Dose adjustments of PERJETA are not needed in patients with mild (creatinine clearance [CLcr] 60 to 90 mL/min) or moderate (CLcr 30 to 60 mL/min) renal impairment. No dose adjustment can be recommended for patients with severe renal impairment (CLcr less than 30 mL/min) because of the limited pharmacokinetic data available [see Clinical Pharmacology (12.3)]. 8.8 Hepatic Impairment No clinical studies have been conducted to evaluate the effect of hepatic impairment on the pharmacokinetics of pertuzumab. 10 OVERDOSAGE No drug overdoses have been reported with PERJETA to date.

7 DRUG INTERACTIONS No drug-drug interactions were observed between pertuzumab and trastuzumab, or between pertuzumab and docetaxel. 8 USE IN SPECIFIC POPULATIONS 8.1 Pregnancy Pregnancy Category D Risk Summary There are no adequate and well-controlled studies of PERJETA in pregnant women. Based on findings in animal studies, PERJETA can cause fetal harm when administered to a pregnant woman. The effects of PERJETA are likely to be present during all trimesters of pregnancy. Pertuzumab administered to pregnant cynomolgus monkeys resulted in oligohydramnios, delayed fetal kidney development, and embryo-fetal deaths at clinically relevant exposures of 2.5 to 20-fold greater than the recommended human dose, based on Cmax. If PERJETA is administered during pregnancy, or if a patient becomes pregnant while receiving PERJETA, the patient should be apprised of the potential hazard to the fetus. If PERJETA is administered during pregnancy or if a patient becomes pregnant while receiving PERJETA, immediately report exposure to the Genentech Adverse Event Line at 1-888-835-2555. Encourage women who may be exposed during pregnancy to enroll in the MotHER Pregnancy Registry by contacting 1-800-690-6720 [see Patient Counseling Information (17)]. Animal Data Reproductive toxicology studies have been conducted in cynomolgus monkeys. Pregnant monkeys were treated on Gestational Day (GD)19 with loading doses of 30 to 150 mg/kg pertuzumab, followed by bi-weekly doses of 10 to 100 mg/kg. These dose levels resulted in clinically relevant exposures of 2.5 to 20-fold greater than the recommended human dose, based on Cmax. Intravenous administration of pertuzumab from GD19 through GD50 (period of organogenesis) was embryotoxic, with dose-dependent increases in embryo-fetal death between GD25 to GD70. The incidences of embryo-fetal loss were 33, 50, and 85% for dams treated with bi-weekly pertuzumab doses of 10, 30, and 100 mg/kg, respectively (2.5 to 20-fold greater than the recommended human dose, based on Cmax). At Caesarean section on GD100, oligohydramnios, decreased relative lung and kidney weights and microscopic evidence of renal hypoplasia consistent with delayed renal development were identified in all pertuzumab dose groups. Pertuzumab exposure was reported in offspring from all treated groups, at levels of 29% to 40% of maternal serum levels at GD100. 8.3 Nursing Mothers It is not known whether PERJETA is excreted in human milk, but human IgG is excreted in human milk. Because many drugs are secreted in human milk and because of the potential for serious adverse reactions in nursing infants from PERJETA, a decision should be made whether to discontinue nursing, or discontinue drug, taking into account the elimination half-life of PERJETA and the importance of the drug to the mother [See Warnings and Precautions (5.1), Clinical Pharmacology (12.3)]. 8.4 Pediatric Use The safety and effectiveness of PERJETA have not been established in pediatric patients. 8.5 Geriatric Use Of 402 patients who received PERJETA in the randomized trial, 60 patients (15%) were ≥ 65 years of age and 5 patients (1%) were ≥ 75 years of age. No overall differences in efficacy and safety of PERJETA were observed between these patients and younger patients. Based on a population pharmacokinetic analysis, no significant difference was observed in the pharmacokinetics of pertuzumab between patients < 65 years (n=306) and patients ≥ 65 years (n=175). 8.6 Females of Reproductive Potential PERJETA can cause embryo-fetal harm when administered during pregnancy. Counsel patients regarding pregnancy prevention and planning. Advise females of reproductive potential to use effective contraception while receiving PERJETA and for 6 months following the last dose of PERJETA.

European Cancer Congress Bevacizumab in Ovarian Cancer continued from page 6

An updated safety analysis did not reveal any new safety concerns from the previous safety analysis in 2012, she said. The main grade 3 or higher toxicities in the bevacizumab arm were hypertension (7.8%) and proteinuria (2.2%).

ICON7 In the ICON7 trial, the previously reported primary analysis of progressionfree survival demonstrated the benefit of bevacizumab added to standard chemotherapy in newly diagnosed ovarian cancer: 19 vs 17.3 months (P = .0041).3 In the final survival analysis presented at the ECC, median overall survival was 58 months in the study for both arms. However, poor-prognosis patients experienced a 4.8-month prolongation of survival (from 34.5 to 39.3 months) if they received bevacizumab. “The survival benefit in the overall trial of 0.9 months [using a restricted means analysis] is not clinically meaningful. However in the high-risk subgroup, bevacizumab did show a clinically meaningful benefit of 4.8 months,” said Amit M. Oza, MD, of Princess Margaret Cancer Center, University of Toronto, Canada. The study was conducted at 263 sites around the world and randomly assigned 1,528 women to six cycles of every-3-week carboplatin/paclitaxel vs carboplatin/paclitaxel plus bevacizu­ mab for five or six cycles followed by bevacizumab for 12 additional every-3-week cycles until disease progression. One-third of the women were considered high risk (stage III with > 1 cm residual disease,

stage IV, and nondebulked). Patients were prestratified according to stage, extent of debulking, and time of therapy.

Key Findings At a median follow-up of 49 months, progression-free survival was not significantly different between the two arms, similar to the first interim analysis presented previously. Because nonproportional hazards were detected, the final overall survival analysis was conducted using restricted mean survival time, and the difference between the two arms was 0.9 months, which was not statistically or clinically meaningful, Dr. Oza said. In a predefined high-risk subgroup of patients, the overall survival curves for the two arms separated, and the bevacizumab arm did better throughout the study, with a 4.8-month improvement over the control arm. Dr. Oza said this difference was “highly clinically meaningful, with a significant interaction between treatment and survival in high-risk patients.” Bevacizumab showed a significant effect according to stage and amount of residual disease, with a greater impact on higher stage and greater burden of disease, he added. n

EXPERT POINT OF VIEW

F

ormal discussant of the AURELIA and ICON7 presentations, Rebecca Kristeleit, MD, University College London Hospital, London, said that a consistent message in both trials was the benefit of bevacizumab (Avastin) in high-risk disease. “Angiogenesis seems to be a particular driver of advanced disease, enabling growth and metastasis in the peritoneal space. The rationale for adding bevacizumab to chemotherapy is to accomplish a twofold normalization of vasculature, to starve the tumor,” she explained.

Specific Considerations ICON7 showed that in the high-risk subgroup, bevacizumab was of benefit. This included women with residual or stage IV disease, and those who had not undergone surgery. But in stage III patients with no residual disease, no benefit was seen with the addition of bevacizumab. “The [progression-free and overall survival differences] are clinically meaningful and statistically significant [in the high-risk patients],” Dr. Kristeleit stated. “There is no survival benefit in any of the other subgroups.” “However, bevacizumab doesn’t improve the cure rate. A remaining question is whether maintenance therapy will improve survival, she said. Turning to AURELIA, she said, “The bottom line is that the [progressionfree survival] doubled in this hard-to-treat ovarian cancer group where there is significant clinical need. The best survival results in the weekly paclitaxel group were seen in an exploratory analysis, and the true benefit of bevacizumab is difficult to tease out.” The study suggests that patients relapsing within 3 months of platinum therapy may not have the same benefit from the addition of bevacizumab, she pointed out.

‘Practice-Changing’ Studies Dr. Kristeleit called AURELIA and ICON7 “practice-changing.” She continued, “Bevacizumab with weekly paclitaxel should be considered a new paradigm in platinum-resistant ovarian cancer. This combination has the most favorable clinical and cost-benefit ratio…. And first-line therapy with bevacizumab and 3-weekly chemotherapy should be considered a standard of care in high-risk ovarian cancer.” n Disclosure: Dr. Kristeleit reported no potential conflicts of interest.

European Cancer Congress Important News Briefs: New Data Reported in Breast, Renal Cell, Head and Neck, and Lung Cancer By Caroline Helwick and Alice Goodman

T

he 2013 European Cancer Congress (ECC), held September 27 to October 1 in Amsterdam, was jointly sponsored by the European Society of Medical Oncology, the European Cancer Organization, and the European Society of Radiation Oncology. With the Congress theme being “Reinforcing Multidisciplinarity,” ECC 2013 featured 3,176 scientific abstracts, 121 late-breaking abstracts, and hundreds of lectures and special programs. The ASCO Post has covered key presentations with longer news articles, but here we bring our readers short summaries of other abstracts of interest.

cizumab as first-line therapy also had no impact on overall survival, which was 52 months in each arm, but overall response rates were almost doubled (41% vs 22%; P < .001). “Taking into account the higher toxicity with bevacizumab in addition to endocrine therapy, the overall risk-benefit analysis remains unfavorable. The study of this combination by the [Cancer and Leukemia Group B (CALGB)] should be further informative, said Sibylle Loibl, MD, Associate Professor of Gynecology at the University of Frankfurt, Germany, who presented the study.

Zoledronic Acid in Early Breast Cancer

Dovitinib for Renal Cell Carcinoma

In the phase III NEOZOTAC trial conducted in 247 early breast cancer patients, the addition of bisphosphonates to neoadjuvant chemotherapy (docetaxel, doxorubicin, cyclophosphamide) did not enhance the rates of pathologic complete response or clinical response, reported Ayoub Charehbili, of Leiden University Medical Center in The Netherlands, and colleagues.1 Rates of pathologic complete response were 18% with chemotherapy alone and 18% with chemotherapy plus zoledronic acid. In premenopausal and perimenopausal women, pathologic complete response rates for chemotherapy alone and chemotherapy plus zoledronic acid were 22% and 19%, respectively, and in postmenopausal women, they were 10% and 17%, respectively. While neither of these differences was statistically significant, the investigators felt more research is needed in postmenopausal women. Survival data were not yet mature.

The investigational oral multitargeted tyrosine kinase inhibitor dovitinib had disappointing results as third-line therapy in renal cell carcinoma, failing to meet the primary endpoint of progression-free survival vs sorafenib (Nexavar), according to an interim analysis of an open-label phase III trial.3 Patients enrolled in the trial had shown disease progression despite

Bevacizumab Plus Endocrine Therapy for Advanced Breast Cancer The LEA study failed to demonstrate a statistically significant increase in progression-free survival with the addition of bevacizumab (Avastin) to endocrine therapy as first-line treatment for advanced breast cancer.2 Median progression-free survival was 14.4 months for endocrine therapy alone and 19.3 months for endocrine therapy plus bevacizumab (P = .126) No differences according to subgroups were observed.

prior vascular endothelial growth factor (VEGF)/mammalian target of rapamycin (mTOR)-targeted therapies. The “positives” of the trial are acceptable safety with dovitinib, and that it is a landmark trial for future third-line studies in renal cell carcinoma. Lead author Robert J. Motzer, MD, a medical oncologist at Memorial Sloan-Kettering Cancer Center (MSKCC), New York, said that more effective drugs are needed for patients whose disease progresses after treatment with VEGF-targeted therapies and mTOR inhibitors. The phase III GOLD trial compared dovitinib vs sorafenib, a drug approved for second-line treatment of renal cell carcinoma. Patients en-

Notable Findings From the European Cancer Congress 2013 ■■ In the phase III NEOZOTAC trial in 247 early breast cancer patients, the addition of bisphosphonates to neoadjuvant chemotherapy failed to enhance pathologic complete response or clinical response rates.

rolled in the trial had metastatic renal cell carcinoma and received one prior VEGF-targeted therapy and one prior mTOR inhibitor. All patients had shown disease progression within 6 months of their last targeted therapy. As of March 2011, 570 patients were enrolled; 284 were randomly assigned to dovitinib and 286 to sorafenib. The interim data were from a cutoff of April 2013. At baseline, about 23% were classified as poor risk according to MSKCC criteria and between 35% and 42% had bone metastasis. Sunitinib (Sutent) was used as prior VEGF therapy in 90% of patients, and everolimus (Afinitor) was the predominant prior mTOR inhibitor (> 85% of patients). At the time of analysis, 495 patients were off study, mainly due to progressive disease. The primary endpoint of progression-free survival by central review was not met. Median progression-free survival was 3.7 months for dovitinib vs 3.6 months for sorafenib, a nonsignificant difference. Median progression-free survival by investigator assessment was 3.9 months for both arms. Subgroup analysis of progression-free survival

showed no significant difference between the two arms. Median overall survival was 11.1 months for dovitinib and 11 months for sorafenib. Nausea, diarrhea, and vomiting were the most common adverse events with dovitinib. Hypertension, hand/foot syndrome, and alopecia were more common in the sorafenib group. Formal discussant of this trial, James Larkin, PhD, FRCP, Consultant Medical Oncologist at The Royal Marsden Hospital, London, said the study confirms that sorafenib is a relevant benchmark for new therapies in this setting. However, predictive markers for response are greatly needed.

Everolimus in Papillary Renal Cell Carcinoma The mTOR inhibitor everolimus showed clinical efficacy for the initial treatment of advanced papillary renal cell carcinoma, according to the phase II results of the RAPTOR trial presented by Bernard J.

European Cancer Congress type DX recurrence score assay may accurately predict risk of recurrence, ­Marlies S. Reimers, MD, a PhD student in the Department of Surgery at Leiden University in The Netherlands, reported at the meeting.5 The 308 stage II and III patients from the Dutch total mesorectal excision trial had been treated with total

Marlies S. Reimers, MD

mesorectal excision surgery alone, without neoadjuvant or adjuvant treatment. Recurrence score was determined for 297 patients. At a median follow-up of 11 years, recurrence score predicted the risk of recurrence (P = .011), the risk of distant recurrence (P = .030), and rectal cancer–specific survival (P = .007).

The effect of the recurrence score was most prominent in stage II rectal cancer and attenuated with more advanced stages. In stage II patients, the 5-year recurrence risk ranged from 12% in the low recurrence score group to 53% in the high recurrence score group; 5-year rectal cancer–specific mortality ranged from 5% to 37%, respectively. The investigators concluded that the recurrence score may be especially clinically useful in patients with stage II rectal cancer, by identifying high-risk patients who could benefit from adjuvant chemotherapy, and excluding low-risk patients.

Altered Fractionation for Head and Neck Cancer Compared with standard radiation, the use of altered-fractionation radiotherapy increased overall survival in patients with locally advanced head and neck cancers in a meta-analysis presented by Pierre Blanchard, MD, a radiation oncologist from the Institut Gustave Roussy, Villejuif, France.6

“The improvement in survival is marked for patients in the hyperfractionated regimen, with an absolute benefit of 8.1% at 5 years,” he reported. Dr. Blanchard and colleagues examined randomized trials comparing standard radiation therapy with altered-fractionation radiotherapy with or without concomitant chemotherapy in patients with local head and neck squamous cell carcinomas. Fractionation was defined as either standard (5 fractions per week for 7 weeks) or altered therapy, which could have been either hyperfractionated (10 fractions per week for 7 weeks resulting in a higher dose); accelerated (same dose given over 6 weeks); or very accelerated (low dose given in about 3 weeks). The researchers collected data from 31 trials representing more than 11,500 patients. After 7 years of follow-up, the higher dose intensity of altered-fractionation radiotherapy improved outcomes. continued on page 18

“The hyperfractionated [regimen] is the most effective in terms of overall survival. Indeed, in this group of trials the risk of death is reduced by 18% by the use of hyperfractionated radiotherapy, with 41% of patients alive at 5 years compared to 33% in the [standard-fractionation radiotherapy] group.

The trial was conducted in eight countries at 73 clinical sites and enrolled 532 patients (42 with stage IIIA and 490 with stage IIIB/IV) who had not shown disease progression on front-line therapy. At 4 to 17 weeks following chemotherapy, patients were randomly assigned in a 1:1 ratio to double-blind therapy with the vaccine

prove survival vs placebo when used as maintenance therapy in a phase III study of patients with advanced non– small cell lung cancer (NSCLC) without disease progression (responding or stable disease) after chemotherapy.7 “Most tumors use [transform-

or placebo as maintenance therapy. The vaccine is composed of four different allogeneic NSCLC cell lines genetically modified to block TGFbeta. The cells are irradiated and cryopreserved until the vaccine is used. The vaccine was given as 18 monthly injections followed by two quarterly injections. At 6 months of follow-up, overall survival was 20.3 months in the vaccine arm vs 17 months in the placebo arm, which was much higher than anticipated for placebo. Median overall survival is typically about 10.4 months for patients with stage IV disease given a chemotherapy doublet, Dr. Giaccone said. In this study, there were patients with stage IIIA and IIIB disease who did better, he added. An exploratory subgroup analysis showed that patients enrolled within 12 weeks of chemotherapy had a trend toward improved survival in the vaccine arm. “In several subgroups of patients randomized within 12 weeks, the results were positive enough to warrant another study,” Dr. Giaccone noted.

The rate of serious adverse events was low, with only five patients experiencing one of these events. The most common adverse events were local reactions, including injection site reaction, erythema, induration, rash, and local effects.

Patient Selection for Lung Cancer CT Screening According to a late-breaking abstract, the most efficient use of annual lung cancer computed tomography (CT) screening is in people between the ages of 55 and 80 with at least 30 pack-years of smoking and who quit within 15 years, reported Harry J. de Koning, MD, PhD, Professor of Epidemiology at Erasmus University Medical Center, Rotterdam, The Netherlands.8 Dr. de Koning and colleagues modeled a hypothetical cohort of 100,000 people based on the U.S. National Lung Screening Trial (NLST), which showed a 20% reduction in mortality with CT screening of high-risk populations. “If you go above that strategy, you exceed the harms, with more radiation exposure, more overdiagnosis and overtreatment, and higher cost,” he said. Dr. de Koning and his co-investigators used five different models to estimate the harms and benefits in the study population assuming they were born in 1950 and followed from ages 45 to 90. They evaluated 576 possible scenarios and reported on the 26 considered most efficient using the NLST scenario. In the study, triennial screening programs reduced lung cancer mortality by 5% to 6%, biennial screening programs by 7% to 10%, and annual screening programs by 11% to 21%. If screening were limited to the group they identified (aged 55–80; 30 packyears; quitting within the past 15 years), 19.3% of the cohort would be screened at least once; 287,000 CT screens would be obtained; and 1971 screen-detected cases would be found, 50% of them detected at an early and treatable stage. This would lead to a 14% reduction in lung cancer mortality (avoiding 520 deaths), and 5,500 life-years gained. The conclusion was that 550 screens are needed to avoid one death. These benefits must be balanced against extending screening to groups with less stringent criteria, which would result in 330,000 CT exams, 66,000 false-positive results, and an estimated overdiagnosis rate of 4% (190

lung cancers), as well as 24 deaths due to radiation exposure. n

DNA mismatch repair with prognosis in patients with stage III colon cancer treated with adjuvant FOLFOX (fluorouracil [5-FU], leucovorin, and oxaliplatin) chemotherapy.1 They found that patients with proximal mismatch repair–deficient tumors had favorable outcome, whereas those with distal or N2 mismatch repair–deficient tumors had poor outcome.

Study Details The study population consisted of resected, stage III colon carcinomas from 2,686 patients randomly assigned to FOLFOX alone or combined with the anti-EGFR antibody with or without cetuximab (Erbitux) in the North Central Cancer Treatment Group

ers with disease-free survival was determined. In this trial, the addition of cetuximab to FOLFOX failed to improve disease-free survival overall or in patients with wild-type KRAS tumors. In the full study cohort, deficient DNA mismatch repair was detected in 314 (12%) of 2,580 tumors, and mutations in BRAF V600E and KRAS were detected in 14% and 28% of tumors, respectively. The study required centralized KRAS analysis, and after

the proximal or distal colon was equal in the study population. Patients with proximal vs distal tumors were significantly more likely to be older (median age, 61 vs 56 years, P < .001), female (50% vs 45%, P = .02), and to have tumors with high-grade histology (33% vs 18%, P < .001) and higher T stage (T1 or 2 in 12% vs 18%, T3 in 75% vs 72%, and T4 in 13% vs 10%, P < .001 for trend). Proximal vs distal cancers were significantly more likely to ex-

Mismatch Repair and Key Mutations Deficient DNA mismatch repair (vs proficient mismatch repair) was significantly associated with older age (median, 62 vs 58 years, P < .001), female sex (59% vs 46%, P < .001), proximal site (88% vs 45%, P < .001), high-grade histology (53% vs 22%, P < .001), and higher T stage (P = .008 for trend). The proportion of patients with N2 vs N1 nodal classification did not differ (40% vs 42%). As with deficient mismatch repair, mutated BRAF V600E was significantly associated with older age, female sex, proximal site, high-grade histology, and higher T stage. In contrast to mismatch repair deficiency, BRAF V600E mutations were significantly more common in N2 vs N1 tumors. KRAS mutations were significantly associated with proximal site, low-grade histology, and N1 stage. Mismatch Repair and Tumor Site Of the tumors with deficient mismatch repair in the NCCTG trial population, 49.3% and 10.6% had BRAF V600E and KRAS mutations, respectively.

In Mismatch Repair–Deficient Colon Cancer, Side Matters By Leonard B. Saltz, MD

I

n general, we have come to think of mismatch repair–deficient colon cancer as having a more favorable prognosis, being less likely to metastasize to regional nodes or distant sites, and being resistant to fluoropyrimidines. Much of our data, however, come from trials combining stage II and III patients, and treating them predominantly with fluoropyrimidines alone. In their recent manuscript, reviewed in this issue of The ASCO Post,

Dr. Saltz is Chief of the Gastrointestinal Oncology Service in the Department of Medicine at Memorial Sloan-Kettering Cancer Center, New York.

Sinicrope et al evaluated the impact of mismatch repair deficiency and other potential prognostic indicators in the North Central Cancer Treatment Group (NCCTG) N0147 trial, which treated stage III colon cancer patients with FOLFOX (leucovorin, fluorouracil, and oxaliplatin) with or without cetuximab (Erbitux). Since cetuximab was not active in this situation, both arms were combined for these molecular analyses. The findings, while instructive, are more complex than expected.

Location and Mutation In the overall analysis, mismatch repair status did not correlate with

prognosis. In a deeper analysis, however, mismatch repair status became prognostic when looked at by the side of the colon in which the tumor arose. Within the right, or proximal colon, mismatch repair–deficient tumors had a more favorable disease-free survival, while in the left-sided, or distal portions of the colon, mismatch repair– deficient tumors not only did not have a better prognosis, but rather, trended strongly toward a worse prognosis than mismatch repair–proficient tumors from the same region. Further complicating matters, the site of tumor was itself independently prognostic, with distal, or left-sided tumors, hav-

ing a better prognosis than proximal, or right-sided, tumors regardless of mismatch repair status. In addition, mutation in either KRAS or BRAF independently conferred a worse disease-free survival prognosis in mismatch repair–proficient tumors. This effect was not seen in mismatch repair–deficient tumors; however, the numbers begin to get small at this point, and the possibility of an interaction cannot be reliably excluded on the basis of these data. The degree of nodal involvement was also independently prognostic in both mismatch repair–proficient continued on page 26


KADCYLA®: The first antibody-drug conjugate for HER2-positive metastatic breast cancer 1

Indication

KADCYLA® (ado-trastuzumab emtansine), as a single agent, is indicated for the treatment of patients with HER2-positive (HER2+), metastatic breast cancer (MBC) who previously received trastuzumab and a taxane, separately or in combination. Patients should have either: received prior therapy for metastatic disease, or developed disease recurrence during or within six months of completing adjuvant therapy.

Important Safety Information Boxed WARNINGS: HEPATOTOXICITY, CARDIAC TOXICITY, EMBRYO-FETAL TOXICITY • Do Not Substitute KADCYLA for or with Trastuzumab • Hepatotoxicity: Serious hepatotoxicity has been reported, including liver failure and death in patients treated with KADCYLA. Monitor serum transaminases and bilirubin prior to initiation of KADCYLA treatment and prior to each KADCYLA dose. Reduce dose or discontinue KADCYLA as appropriate in cases of increased serum transaminases or total bilirubin • Cardiac Toxicity: KADCYLA administration may lead to reductions in left ventricular ejection fraction (LVEF). Evaluate left ventricular function in all patients prior to and during treatment with KADCYLA. Withhold treatment for clinically significant decrease in left ventricular function • Embryo-Fetal Toxicity: Exposure to KADCYLA can result in embryo-fetal death or birth defects. Advise patients of these risks and the need for effective contraception Please see the following pages for additional important safety information and brief summary of full prescribing information, including Boxed WARNINGS.


The next era of treatment KADCYLA contains 3 components: the active antibody trastuzumab, the cytotoxic agent DM1, and a stable linker1-3 In preclinical studies:

Trastuzumab (monoclonal antibody) Binds to HER2 at subdomain IV to suppress downstream signaling

DM1* (cytotoxic maytansinoid) Inhibits tubulin polymerization to induce cell-cycle arrest and cell death

MCC* (stable linker) Stabilizes KADCYLA in circulation to release DM1 after entering the target cell

• Maintains the HER2 suppression and anticancer activities of trastuzumab1 • Delivers cytotoxic DM1 to target HER2-expressing cells1 — Many normal cells express HER24 — Some cancer cells overexpress up to 200 times more HER2 than normal cells4

*Emtansine is the combination of DM1, a cytotoxic maytansinoid, and the stable MCC linker.

woman. There are no adequate and well-controlled studies of KADCYLA in pregnant women and no reproductive and developmental toxicology studies have been conducted with ado-trastuzumab emtansine. Nevertheless, treatment with trastuzumab, the antibody component of KADCYLA, during pregnancy in the postmarketing setting has resulted in oligohydramnios, some associated with fatal pulmonary hypoplasia, skeletal abnormalities and neonatal death. DM1, the cytotoxic component of KADCYLA, can be expected to cause embryo-fetal toxicity based on its mechanism of action. If KADCYLA is used during pregnancy, or if the patient becomes pregnant while receiving KADCYLA, apprise the patient of the potential hazard to the fetus [see Use in Specific Populations (8.1)]. Verify pregnancy status prior to the initiation of KADCYLA. Advise patients of the risks of embryo-fetal death and birth defects and the need for contraception during and after treatment. Advise patients to contact their healthcare provider immediately if they suspect they may be pregnant. If KADCYLA is administered during pregnancy or if a patient becomes pregnant while receiving KADCYLA, immediately report exposure to the Genentech Adverse Event Line at 1-888-835-2555. Encourage women who may be exposed during pregnancy to enroll in the MotHER Pregnancy Registry by contacting 1-800-690-6720 [see Patient Counseling Information (17)].

• Hepatotoxicity: Serious hepatotoxicity has been reported, including liver failure and death in patients treated with KADCYLA. Monitor serum transaminases and bilirubin prior to initiation of KADCYLA treatment and prior to each KADCYLA dose. Reduce dose or discontinue KADCYLA as appropriate in cases of increased serum transaminases or total bilirubin. (2.2, 5.1) • Cardiac Toxicity: KADCYLA administration may lead to reductions in left ventricular ejection fraction (LVEF). Evaluate left ventricular function in all patients prior to and during treatment with KADCYLA. Withhold treatment for clinically significant decrease in left ventricular function. (2.2, 5.2) • Embryo-Fetal Toxicity: Exposure to KADCYLA can result 5.4 Pulmonary Toxicity in embryo-fetal death or birth defects.

Serious hepatobiliary disorders, including at least two fatal cases of severe drug-induced liver injury and associated hepatic encephalopathy, have been reported in clinical trials with KADCYLA. Some of the observed cases may have been confounded by comorbidities and/or concomitant medications with known hepatotoxic potential. Monitor serum transaminases and bilirubin prior to initiation of KADCYLA treatment and prior to each KADCYLA dose. Patients with known active hepatitis B virus or hepatitis C virus were excluded from Study 1 [see Clinical Studies (14.1)]. Reduce the dose or discontinue KADCYLA as appropriate in cases of increased serum transaminases and/or total bilirubin [see Dosage and Administration (2.2)]. Permanently discontinue KADCYLA treatment in patients with serum transaminases > 3 x ULN and concomitant total bilirubin > 2 x ULN. KADCYLA has not been studied in patients with serum transaminases > 2.5 x ULN or bilirubin > 1.5 x ULN prior to the initiation of treatment. In clinical trials of KADCYLA, cases of nodular regenerative hyperplasia (NRH) of the liver have been identified from liver biopsies (3 cases out of 884 treated patients). Two of these three cases of NRH were observed in the randomized trial (Study 1) [see Adverse Reactions (6.1)]. NRH is a rare liver condition characterized by widespread benign transformation of hepatic parenchyma into small regenerative nodules; NRH may lead to non-cirrhotic portal hypertension. The diagnosis of NRH can be confirmed only by histopathology. NRH should be considered in all patients with clinical symptoms of portal hypertension but with normal transaminases and no manifestations of cirrhosis. Upon diagnosis of NRH, KADCYLA treatment must be permanently discontinued. 5.2 Left Ventricular Dysfunction Patients treated with KADCYLA are at increased risk of developing left ventricular dysfunction. A decrease of LVEF to < 40% has been observed in patients treated with KADCYLA. In the randomized trial (Study 1), left ventricular dysfunction occurred in 1.8% of patients in the KADCYLA-treated group and 3.3% of patients in the lapatinib plus capecitabine-treated group [see Adverse Reactions (6.1)]. Assess LVEF prior to initiation of KADCYLA and at regular intervals (e.g. every three months) during treatment to ensure the LVEF is within the institution’s normal limits. Treatment with KADCYLA has not been studied in patients with LVEF < 50% prior to initiation of treatment. If, at routine monitoring, LVEF is < 40%, or is 40% to 45% with a 10% or greater absolute decrease below the pretreatment value, withhold KADCYLA and repeat LVEF assessment within approximately 3 weeks. Permanently discontinue KADCYLA if the LVEF has not improved or has declined further [see Dosage and Administration (2.2)]. Patients with a history of symptomatic congestive heart failure (CHF), serious cardiac arrhythmia, or history of myocardial infarction or unstable angina within 6 months were excluded from Study 1 [see Clinical Studies (14.1)].

Validation in an Independent Study Cohort An independent cohort of 1,264 patients with stage III colon cancer randomly assigned to receive 5-FU/ leucovorin or 5-FU/leucovorin plus irinotecan in the phase III Cancer and Leukemia Group B 89803 adjuvant trial was used for validation. No difand 13.5% in the lapatinib plus capecitabine-treated group [see Adverse Reactions (6.1)]. The incidence of ≥ Grade 3 peripheral neuropathy was 2.2% in the KADCYLA-treated group and 0.2% in the lapatinib plus capecitabine-treated group. KADCYLA should be temporarily discontinued in patients experiencing Grade 3 or 4 peripheral neuropathy until resolution to ≤ Grade 2. Patients should be clinically monitored on an ongoing basis for signs or symptoms of neurotoxicity [see Nonclinical Toxicology (13.2)]. 5.8 HER2 Testing Detection of HER2 protein overexpression or gene amplification is necessary for selection of patients appropriate for KADCYLA therapy because these are the only patients studied for whom benefit has been shown [see Indications and Usage (1), Clinical Studies (14.1)]. In the randomized study (Study 1), patients with breast cancer were required to have evidence of HER2 overexpression defined as 3+ IHC by Dako Herceptest™ or evidence of overexpression defined as FISH amplification ratio ≥ 2.0 by Dako HER2 FISH PharmDx™ test kit. Only limited data were available for patients whose breast cancer was positive by FISH and 0 or 1+ by IHC. Assessment of HER2 status should be performed by laboratories with demonstrated proficiency in the specific technology being utilized. Improper assay performance, including use of suboptimally fixed tissue, failure to utilize specified reagents, deviation from specific assay instructions, and failure to include appropriate controls for assay validation, can lead to unreliable results. 5.9 Extravasation In KADCYLA clinical studies, reactions secondary to extravasation have been observed.

In the NCCTG cohort, mutations in BRAF V600E (HR = 1.37; 95% CI = 1.08–1.70, P = .009) or mutations in KRAS (HR = 1.44; 95% CI = 1.21–1.70, P < .001) were independently associated with significantly worse disease-free survival. Diseasefree survival among patients with mismatch repair–deficient tumors did not differ significantly according to mutant vs wild-type BRAF V600E (adjusted HR = 1.58; P = .12) or mutant vs wild-type KRAS. Among the larger number of patients with mismatch repair–proficient tumors, mutated BRAF V600E was associated with significantly worse disease-free survival (adjusted HR = 1.32, P = .044), as was mutated KRAS (adjusted HR = 1.45, P < .001). However, neither the mismatch repair by BRAF V600E status (adjusted P = .93) nor the mismatch repair by KRAS status (adjusted P = .38) interaction tests were statistically significant. The investigators concluded: [T]he prognostic impact of [deficient DNA mismatch repair] on [diseasefree survival] was dependent on the primary tumor site in patients with stage III colon cancer, and this finding was validated in an independent cohort. Poor prognostic subgroups were observed within [mismatch repair–deficient] cancers that included distal site and N2 disease, which may have contributed to the nonsignificant overall impact of [deficient DNA mismatch repair] on [disease-free survival]. Mutations in BRAF V600E or KRAS were each independently associated with reduced [disease-free survival] and may therefore provide clinically useful prognostic information in FOLFOX-treated patients. n B:11.5”

8.3 Nursing Mothers It is not known whether KADCYLA, specifically, is excreted in human milk, but IgG is known to be excreted in human milk. In lactating monkeys, trastuzumab was excreted in small amounts (about 0.3% of maternal serum concentrations) in breast milk after post-partum doses of 25 mg/kg (about 7 times the clinical dose of KADCYLA). Because many drugs are excreted in human milk and because of the potential for serious adverse reactions in nursing infants from KADCYLA, a decision should be made whether to discontinue nursing or discontinue KADCYLA, taking into account the importance of the drug to the mother [see Warnings and Precautions (5.3)].

and mismatch repair–deficient tumors, with N2 tumors having a worse prognosis than N1 tumors.

Underlying Physiology Why should location within the colon carry such strong prognostic implications? The answer is not clear, but it may be instructive to recall that the distal portion of the large intestine, from the cloaca through the distal third of the transverse colon, is embryologically derived from the hindgut, which is drained by the inferior mesenteric vein, whereas the proximal colon, from the cecum through the proximal twothirds of the transverse colon, is derived from the midgut, and is drained by the superior mesenteric vein. To what degree these differences in embryologic origin and/or vascular drainage contribute to the prognostic implications of the tumor location is not known at this point. However, it is reasonable to speculate that these issues may contribute to the differences observed.

Practical Implications The more immediate question, however, is how can we utilize this in-

formation today? From a clinical trials perspective, these prognostic data can be used to either stratify patients prospectively in new trials, or to evaluate for potential imbalances that may either explain or invalidate apparent differences in already-accrued trials. From a current patient care perspective, however, it is not yet possible to reliably bring these data into the decision-making process, since these data are prognostic and not predictive. Prognostic data tell us who has a better or worse chance of a successful outcome, but they do not tell us whether we are able to influence that outcome. In fact, by definition, we cannot influence the outcome, or

the information would be predictive, rather than prognostic. We cannot choose which side of the colon our patient’s tumor will arise in, nor can we influence the mismatch repair or other mutational status of our patient’s tumor. Predictive data, which would tell us who is or is not likely to benefit from a treatment or intervention, are not derivable from the current report, since all patients effectively received the same treatment.

Actionable Markers Needed At present, oxaliplatin plus a fluoropyrimidine remains the recommended adjuvant therapy for all patients with stage III colon cancer

in the absence of medical contraindications. While it is reasonable to conjecture that some of the prognostic subgroups may either benefit more or fail to benefit from a particular maneuver, such as chemotherapy or oxaliplatin-based chemotherapy, we simply do not know yet if this is the case. It is therefore important to recognize that these interesting data, while informing us about who is more likely to have a favorable outcome, do not yet help us figure out who is or is not likely to have an improved outcome as the result of one intervention or another. It would be highly desirable to have data that define subgroups of stage III patients whose prognoses do not improve with oxaliplatin, so that these patients could be spared the unnecessary toxicity, or to define subgroups who would likely benefit from irinotecan, cetuximab, or other agents. We are not there yet, and these current data should not be misconstrued as such, but analyses of this type in other trials will hopefully provide us with actionable predictive markers in the near future. n Disclosure: Dr. Saltz is a consultant for Roche, Genentech, Bristol-Myers Squibb, Sanofi, and Pfizer.

One Dose of HPV 16/18 Vaccine Produces Durable Response, Study Finds By Jo Cavallo

R

esults from the Costa Rica HPV 16/18 Vaccine Trial indicate that 4-year efficacy against 12-month HPV 16/18 persistent infection was similarly high among women who received one, two, or the recommended three doses of the bivalent HPV16/18 L1 virus-like particle vaccine (Cervarix). The findings suggest that vaccination schedules of two or even one HPV vaccine dose could simplify the logistics and reduce the cost of vaccination in the developing world, where more than 85% of cervical cancers occur. The study results were published in Cancer Prevention Research.1

Study Method Mahboobeh Safaeian, PhD, an Investigator in the Division of Cancer Epidemiology and Genetics at the National Cancer Institute, and colleagues analyzed data from the Na-

tional Cancer Institute–funded phase III Costa Rica HPV 16/18 Vaccine Trial trial to look for the presence of an immune response to the HPV 16/18 vaccine, which was measured by antibody levels. About 20% of the women in the study received fewer than three doses of the vaccine, not by design. Blood samples were drawn from 78, 192, and 120 women who received one, two, and three doses of the vaccine, respectively. The researchers then compared the results with data from 113 women who did not receive the vaccine, but had antibodies against the viruses in their blood because they were infected with HPV in the past.

Findings The researchers found that 100% of the women in all three groups had antibodies against HPV 16 and 18 in

their blood for up to 4 years. In addition, antibody levels were comparable for women receiving two doses 6 months apart and those receiving the full three-dose regimen. Although antibody levels among women who had received one dose of the vaccine were lower than among those women who had received three doses, the levels appeared stable, suggesting that these are lasting responses. “The findings suggest that antibody titers induced by two or three vaccine doses may be substantially higher than needed for long-term protection,” wrote the researchers. The study also found that the levels of antibodies in women from the one- and two-dose groups were 24 times higher than the levels of antibodies in women who did not receive the vaccine, but had prior HPV infection.

“We hope to expand our study to include a longer follow-up because with this vaccine, and probably any other vaccine, you want the protection to last long-term, and we are definitely interested in showing what happens over the next 4 years and even 10 years,” said Dr. Safaeian. n

Disclosure: Dr. Safaeian reported no potential conflicts of interest. The trial was sponsored by the NCI with funding support from the National Institutes of Health Office of Research on Women’s Health, and the Ministry of Health of Costa Rica. GlaxoSmithKline provided the vaccine for the study.

Long-Term Colorectal Cancer Incidence and Mortality After Lower Endoscopy By Matthew Stenger

C

olonoscopy and sigmoidoscopy have been shown to provide protection against colorectal cancer, but the magnitude and duration of protection, particularly against proximal colon cancer, remain undefined. A study of long-term colorectal cancer incidence and mortality after lower endoscopy reported in The New England Jour­ ishihara, nal of Medicine by Reiko N PhD, of Dana-Farber Cancer Institute and Harvard Medical School, and colleagues found that both colonoscopy and sigmoidoscopy for any indication

In the entire population, multivariate hazard ratios (HRs) for colorectal cancer for participants who had undergone endoscopy for any indication vs those not undergoing endoscopy were 0.57 (95% confidence interval [CI] = 0.45–0.72) after removal of adenomatous polyps, 0.60 (95% CI = 0.53–0.68) after negative sigmoidoscopy, and 0.44 (95% CI = 0.380.52) after negative colonoscopy. The findings were consistent among men and women and for all disease stages at presentation.

Colorectal cancer diagnosed within 5 years after colonoscopy was more likely than cancer diagnosed after that period or without prior endoscopy to have [CpG island methylator phenotype] and microsatellite instability. —Reiko Nishihara, PhD, and colleagues

were associated with a reduced incidence of overall colorectal cancer and distal colorectum cancer, with only colonoscopy being associated with a reduction in the incidence of proximal colon cancer.1 Screening colonoscopy and sigmoidoscopy were both associated with reduced overall colorectal cancer mortality and mortality from distal colorectum cancer, with only colonoscopy being associated with reduced mortality from proximal colon cancer.

Study Details The study examined the association of use of lower endoscopy (updated biennially from 1988 through 2008) with colorectal cancer incidence (through June 2010) and mortality (through June 2012) among participants in the Nurses’ Health Study and the Health Professionals Follow-up Study. Among 88,902 participants, including 31,736 men and 57,166 women, a total of 1,815 incident cases of colorectal cancer (714 in men and 1,101 in women) and 474 deaths (187 in men and 287 in women) from colorectal cancer were identified during 22 years of followup, representing a total of 1,738,396 person-years.

For distal colorectal cancer, hazard ratios were 0.40 (95% CI = 0.27–0.59) after polypectomy, 0.44 (95% CI = 0.36–0.53) after negative sigmoidoscopy, and 0.24 (95% CI = 0.18–0.32) after negative colonoscopy. Only negative colonoscopy was associated with significantly reduced risk of proximal colon cancer (HR = 0.73, 95% CI = 0.57–0.92). Findings with regard to colorectal cancer incidence were similar for screening endoscopy.

Colonoscopy Interval Compared with no endoscopy, multivariate hazard ratios for colorectal cancer according to time since last negative colonoscopy were 0.35 (95% CI = 0.28–0.45) for an interval of ≤ 3.0 years, 0.40 (95% CI = 0.31–0.52) for 3.1 to 5.0 years, 0.52 (95% CI = 0.38– 0.70) for 5.1 to 10.0 years, and 0.26 (95% CI = 0.12–0.59) for 10.1 to 15.0

years. Hazard ratios for the interval of 5.1 to 15.0 years were 0.60 (95% CI = 0.38–0.94) for proximal colon cancer and 0.35 (95% CI = 0.22–0.54) for distal colorectal cancer. Compared with no endoscopy, participants who had undergone endoscopy with removal of adenomatous polyps had a reduced incidence of colorectal cancer with surveillance intervals of ≤ 3.0 years (multivariate HR = 0.48, 95% CI = 0.33–0.69) and 3.1 to 5.0 years (HR = 0.49, 95% CI = 0.33–0.73). Results were similar for adenomas in the proximal colon and those in the distal colorectum. For participants with high-risk adenoma, the risk reduction was smaller and of shorter duration, with a hazard ratio of 0.70 (95% CI = 0.43–1.14) for the surveillance interval of 3.1 to 5.0 years. For colonoscopies performed at least 4 years apart, compared with no endoscopy, multivariate hazard ratios for colorectal cancer were 0.43 (95% CI = 0.35–0.51) after one negative colonoscopy, 0.32 (95% CI = 0.22– 0.48) after two, and 0.23 (95% CI = 0.08–0.67) after three.

Subgroups Colonoscopy was associated with similar significant reductions in incidence of colorectal cancer across age, body mass index, smoking status, and aspirin use subgroups. Among participants with a family history of colorectal cancer, there was no significant reduction at more than 5 years after colonoscopy (multivariate HR = 0.91, 95% CI = 0.55–1.52), with the reduction at more than 5 years remaining significant in those without a family history (HR = 0.43, 95% CI = 0.32– 0.58; P = .04 for interaction).

Molecular Characteristics A total of 62 cancers diagnosed within 5 years after colonoscopy had

Impact of Endoscopy on Colorectal Cancer ■■ Colonoscopy and sigmoidoscopy for any indication were associated with

a reduced incidence of overall colorectal cancer and distal colorectum cancer, with only colonoscopy being associated with a (modest) reduction in the incidence of proximal colon cancer.

■■ Screening colonoscopy and sigmoidoscopy were both associated with

reduced overall colorectal cancer mortality and mortality from distal colorectal cancer, with only colonoscopy being associated with reduced mortality from proximal colon cancer.

available molecular data. Compared with cancers diagnosed in participants more than 5 years after colonoscopy or in participants with no endoscopy, these cancers were more likely to have CpG island methylator phenotype (multivariate odds ratio [OR] = 2.19, 95% CI = 1.14–4.21), microsatellite instability (OR = 2.10, 95% CI = 1.10–4.02), and an increased LINE-1 methylation level (OR = 3.21 for each 30% increment, 95% CI = 1.29–8.00). BRAF, KRAS, and PIK3CA mutations were not significantly associated with cancer diagnosed within 5 years after colonoscopy.

Screening Endoscopy and Mortality Compared with no screening endoscopy, colorectal cancer mortality was significantly reduced by screening sigmoidoscopy (multivariate HR = 0.59, 95% CI = 0.45–0.76) and screening colonoscopy (HR = 0.32, 95% CI = 0.24–0.45). Screening sigmoidoscopy was associated with reduced mortality from only distal colorectum cancer (HR = 0.31, 95% CI = 0.20–0.49), whereas screening colonoscopy was associated with reduced mortality from both distal colorectal cancer (HR = 0.18, 95% CI = 0.10–0.31) and proximal colon cancer (HR = 0.47, 95% CI = 0.29– 0.76). The investigators concluded: Colonoscopy and sigmoidoscopy were associated with a reduced incidence of cancer of the distal colorectum; colonoscopy was also associated with a modest reduction in the incidence of proximal colon cancer. Screening colonoscopy and sigmoidoscopy were associated with reduced colorectal cancer mortality; only colonoscopy was associated with reduced mortality from proximal colon cancer. Colorectal cancer diagnosed within 5 years after colonoscopy was more likely than cancer diagnosed after that period or without prior endoscopy to have [CpG island methylator phenotype] and microsatellite instability. n

FDA Approves First Extended-Release, Single-Entity Hydrocodone Product

T

he U.S. Food and Drug Administration (FDA) today approved hydrocodone bitartrate extended-release capsules (Zohydro ER) for the management of pain severe enough to require daily, around-the-clock, long-term treatment and for which alternative treatment options are inadequate. The drug, a Schedule II controlled substance under the Controlled Substances Act, is the first FDA-approved single-entity (not combined with an analgesic such as acetaminophen) and extendedrelease hydrocodone product. The new product is in the class of extended-release/long-acting opioid analgesics. Due to the risks of addiction, abuse, and misuse

counseling practices. Hydrocodone bitartrate is the first opioid to be labeled in this manner. The FDA is requiring postmarketing studies of hydrocodone bitartrate to assess the known serious risks of misuse, abuse, hyperalgesia,

addiction, overdose, and death associated with long term use beyond 12 weeks. These studies will also be required for other extended-release/ long-acting opioid analgesics. The safety of hydrocodone bitartrate is based on clinical studies

with opioids, even at recommended doses, and because of the greater risks of overdose and death with extended-release/long-acting opioid formulations, hydrocodone bitartrate should be reserved for use in patients for whom alternative treatment options are ineffective, not tolerated, or would be otherwise inadequate to provide sufficient management of pain. Hydrocodone bitartrate is not approved for asneeded pain relief. The most common side effects of hydrocodone bitartrate are constipation, nausea, drowsiness, fatigue, headache, dizziness, dry mouth, vomiting, and pruritus. New Safety Measures The approved labeling for hydrocodone bitartrate conforms to updated labeling requirements for all extended-release/long-acting opioid analgesics announced by the FDA on September 10, 2013. The new class labeling and stronger warnings will more clearly describe the risks and safety concerns associated with extended-release/ long-acting opioid analgesics, along with the appropriate use of these medications. These warnings are expected to improve the safety of all such medicines by encouraging more appropriate prescribing, patient monitoring, and patient

WARNING: IMMUNE-MEDIATED ADVERSE REACTIONS

YERVOY can result in severe and fatal immune-mediated adverse reactions due to T-cell activation and proliferation. These immune-mediated reactions may involve any organ system; however, the most common severe immune-mediated adverse reactions are enterocolitis, hepatitis, dermatitis (including toxic epidermal necrolysis), neuropathy, and endocrinopathy. The majority of these immune-mediated reactions initially manifested during treatment; however, a minority occurred weeks to months after discontinuation of YERVOY. Assess patients for signs and symptoms of enterocolitis, dermatitis, neuropathy, and endocrinopathy and evaluate clinical chemistries including liver function tests (LFTs) and thyroid function tests at baseline and before each dose. Permanently discontinue YERVOY and initiate systemic high-dose corticosteroid therapy for severe immune-mediated reactions.

and 24% of patients, respectively, have experienced serious adverse vascular events, including fatal and life-threatening heart attack, stroke, loss of blood flow to the extremities resulting in tissue death, and severe narrowing of blood vessels in the extremities, heart,

and brain requiring urgent surgical procedures to restore blood flow. In the phase II clinical trial, adverse events affecting the blood vessels that supply the heart, brain, and extremities were observed in 12%, 6%, and 8% of patients, respectively; patients with and without cardiovascular risk factors, including patients in their 20s, have experienced these

events. High blood pressure occurred in 67% of patients, and heart failure, including fatalities, occurred in 8% of patients treated with ponatinib. In addition, serious adverse reactions involving the eyes, which lead to blindness or blurred vision, occurred in ponatinib-treated patients. In some patients, fatal and serious adverse events have occurred as early

as 2 weeks after starting ponatinib therapy. The relationship of these adverse events to ponatinib has not been determined, but the increasing rate and pattern of the events strongly suggests that many are drug-related. At this time, FDA cannot identify a dose level or exposure duration that is safe.

Oncogene Addiction and the Rationale for Molecular Targeted Therapy in Lung Cancer A Conversation With Fadlo R. Khuri, MD By Jo Cavallo

O

ver the past decade, Fadlo R. Khuri, MD, Professor and Roberto C. Goizueta Distinguished Chair

of Hematology and Medical Oncology, and Deputy Director of the Winship Cancer Institute of Emory University,

Atlanta, has focused his research and clinical career on investigating novel approaches in the treatment and pre-

Clinical Trials Experience

Immunogenicity

Because clinical trials are conducted under widely varying conditions, the adverse reaction rates observed cannot be directly compared with rates in other clinical trials or experience with therapeutics in the same class and may not reflect the rates observed in clinical practice.

In clinical studies, 1.1% of 1024 evaluable patients tested positive for binding antibodies against ipilimumab in an electrochemiluminescent (ECL) based assay. This assay has substantial limitations in detecting anti-ipilimumab antibodies in the presence of ipilimumab. Infusion-related or peri-infusional reactions consistent with hypersensitivity or anaphylaxis were not reported in these 11 patients nor were neutralizing antibodies against ipilimumab detected.

The clinical development program excluded patients with active autoimmune disease or those receiving systemic immunosuppression for organ transplantation. Exposure to YERVOY (ipilimumab) 3 mg/kg for 4 doses given by intravenous infusion in previously treated patients with unresectable or metastatic melanoma was assessed in a randomized, double-blind clinical study (Study 1). [See Clinical Studies (14) in Full Prescribing Information.] One hundred thirty-one patients (median age 57 years, 60% male) received YERVOY as a single agent, 380 patients (median age 56 years, 61% male) received YERVOY with an investigational gp100 peptide vaccine (gp100), and 132 patients (median age 57 years, 54% male) received gp100 peptide vaccine alone. Patients in the study received a median of 4 doses (range: 1–4 doses). YERVOY was discontinued for adverse reactions in 10% of patients. The most common adverse reactions (≥5%) in patients who received YERVOY at 3 mg/kg were fatigue, diarrhea, pruritus, rash, and colitis. Table 1 presents selected adverse reactions from Study 1, which occurred in at least 5% of patients in the YERVOY-containing arms and with at least 5% increased incidence over the control gp100 arm for all-grade events and at least 1% incidence over the control group for Grade 3–5 events.

In a combined study of embryo-fetal and peri-postnatal development, pregnant cynomolgus monkeys received ipilimumab every 3 weeks from the onset of organogenesis in the first trimester through parturition, at exposure levels either 2.6 or 7.2 times higher by AUC than the exposures at the clinical dose of 3 mg/kg of ipilimumab. No treatment-related adverse effects on reproduction were detected during the first two trimesters of pregnancy. Beginning in the third trimester, the ipilimumab treated groups experienced higher incidences of severe toxicities including abortion, stillbirth, premature delivery (with corresponding lower birth weight), and higher incidences of infant mortality in a dose-related manner compared to controls. [See Nonclinical Toxicology (13.2) in Full Prescribing Information.] Human IgG1 is known to cross the placental barrier and ipilimumab is an IgG1; therefore, ipilimumab has the potential to be transmitted from the mother to the developing fetus.

Immunogenicity assay results are highly dependent on several factors including assay sensitivity and specificity, assay methodology, sample handling, timing of sample collection, concomitant medications, and underlying disease. For these reasons, comparison of incidence of antibodies to YERVOY with the incidences of antibodies to other products may be misleading.

Because trough levels of ipilimumab interfere with the ECL assay results, a subset analysis was performed in the dose cohort with the lowest trough levels. In this analysis, 6.9% of 58 evaluable patients, who were treated with 0.3 mg/kg dose, tested positive for binding antibodies against ipilimumab.

Across clinical studies that utilized YERVOY doses ranging from 0.3 to 10 mg/kg, the following adverse reactions were also reported (incidence less than 1% unless otherwise noted): urticaria (2%), large intestinal ulcer, esophagitis, acute respiratory distress syndrome, renal failure, and infusion reaction. Based on the experience in the entire clinical program for melanoma, the incidence and severity of enterocolitis and hepatitis appear to be dose dependent.

It is not known whether ipilimumab is secreted in human milk. In monkeys treated at dose levels resulting in exposures 2.6 and 7.2 times higher than those in humans at the recommended dose, ipilimumab was present in milk at concentrations of 0.1 and 0.4 mcg/mL, representing a ratio of up to 0.3% of the serum concentration of the drug. Because many drugs are secreted in human milk and because of the potential for serious adverse reactions in nursing infants from YERVOY, a decision should be made whether to discontinue nursing or to discontinue YERVOY, taking into account the importance of YERVOY to the mother. Pediatric Use Safety and effectiveness of YERVOY have not been established in pediatric patients. Geriatric Use Of the 511 patients treated with YERVOY at 3 mg/kg, 28% were 65 years and over. No overall differences in safety or efficacy were reported between the elderly patients (65 years and over) and younger patients (less than 65 years). Renal Impairment No dose adjustment is needed for patients with renal impairment. [See Clinical Pharmacology (12.3) in Full Prescribing Information.] Hepatic Impairment No dose adjustment is needed for patients with mild hepatic impairment (total bilirubin [TB] >1.0 × to 1.5 × the upper limit of normal [ULN] or AST >ULN). YERVOY has not been studied in patients with moderate (TB >1.5 × to 3.0 × ULN and any AST) or severe (TB >3 × ULN and any AST) hepatic impairment.

vention of lung and upper aerodigestive tract cancer. His studies—for example, showing that the expression of retinoic acid receptor (RAR) and cyclooxygenase (COX)-2 indicate poor prognosis in lung cancer and prognostic factors such as death-associated protein kinase (DAPK) methylation and lack of interleukin (IL)-10 expression independently predict cancer-specific survival—have spurred a greater understanding of individualized adjuvant therapy for patients with lung cancer. Dr. Khuri’s research in the development of novel cancer drugs has also led to new opportunities to target drivers of oncogene addiction, a phenomenon that describes the use of therapies to enhance the dependency of cancer cells to certain signaling pathways, such as EGFR, ALK, ROS, and RET. Earlier this year, Dr. Khuri was recognized for his research accomplishments in lung and aerodigestive medical oncology at the American Association for Cancer Research Annual Meeting, where he received the Richard and Hinda Rosenthal Memorial Award. In July, Dr. Khuri gave a review of new developments in novel therapeutics for lung cancer at the Debates and Didactics in Hematology and Oncology conference held on Sea Island, Georgia. The ASCO Post talked with him about his presentation, the phenomenon of oncogene addiction, progress being made in lung cancer survival, and the danger of the growing popularity of electronic cigarettes.

Please explain the phenomenon called oncogene addiction and how it provides a rationale for molecular targeted therapy. My original medical school mentor, Dr. I. Bernard Weinstein, coined the term “oncogene addiction” in 2002. It indicates that cancer cells, which develop a dependency on certain oncogenically driven pathways, become disproportionally dependent on those pathways. Examples include EGFR and ALK in lung cancer and HER2/neu in breast cancer. The classic example is BCR-ABL in chronic myelogenous leukemia. Interrupting those pathways by targeting the kinase domain mutation or blocking the oncogenic signaling in

some manner makes the cancer cells much more vulnerable than normal cells because the normal cells are not as “addicted” or dependent on those pathways. Targeting drivers of oncogene addiction has been an area of explosive progress in the past decade. In our view, however, most lung cancer cells are not simply addicted to one oncogenic driver mutation. At the Lung Cancer Mutation Consortium, we looked at over 1,000 lung cancer cases and identified oncogenic drivers in about 64% of those patients. Some of the driver mutations such as EGFR, ALK, ROS, or RET are targetable with novel agents. For others, like RAS, we don’t yet have great drugs or approaches for targeting them. Ultimately we should be able to target the majority of lung adenocarcinomas or squamous cell lung cancers. The challenge will be in overcoming drug resistance that emerges in tumors with those mutations. Drug resistance often develops when the tumor cell acquires a second mutation, which has been shown in some of the ALK and VEGFR data. But we are looking at survival signaling networks to see if there is a way to interrupt or reroute the whole network, using the cancer cell’s dependence on the pathway to make it even more addicted, so that a second hit along that signaling network with a targeted therapy will be devastating for the cancer, without causing serious side effects.

Resistance Mechanisms Which resistance pathways have emerged in lung cancers for first-generation targeted therapies? Some agents such as crizotinib (Xalkori) are effective at targeting MET amplification and ALK and are already in use in the clinic. We are developing agents that target the second EGFR T790 mutation. So it’s an excit-

ing time because we have developed not only drugs that can target reasonably effective approaches to the initial oncogenic driver mutation but also approaches to the second escape mechanism. There is a lot of work going on now in resistance mechanisms and the development of therapies to target them. These are advances patients didn’t have 5 or 10 years ago.

KRAS Mutations In your presentation, you said that targeting KRAS-mutant lung cancer is still a challenge. Could you expand on that? One of the major points of my presentation was about the heat shock

particularly in patients who didn’t have early progression, but people were still disappointed that it didn’t seem to specifically target KRAS-mutant lung cancers.

Immunotherapy How effective are immunotherapies such as PD-L1 in the treatment of lung cancer? Early data on immunotherapy in lung cancer show that responses are small but meaningful. What is interesting about these responses is that they are durable. Now that we have more evidence from clinical studies, we’re starting to

protein (Hsp)90 inhibitors and the GALAXY-1 trial, which combined ­ the Hsp90 inhibitor ganetespib with docetaxel vs docetaxel alone for secondline therapy of lung adenocarcinoma. Although the study data were promising, overall it was a cautionary tale. I was one of the coauthors on the GALAXY-1 abstract presented at the ASCO Annual Meeting this year,2 and we had very interesting data suggesting that ganetespib plus docetaxel vs docetaxel alone seemed to show an advantage in progression-free survival. But that benefit was not specific to patients with KRAS mutations, which is where some of our original hope was, because this is a mutation for which we don’t yet have effective therapies. So here was a trial that looked positive,

understand who can have a really durable response, based on patient biomarkers. But I don’t think we have the final answer on PD-L1 because PD-L1 staining on the tumors of about 20% of responders has been negative.

Longer Remissions, No Cures More effective therapies have resulted in extended remissions for patients with advanced lung cancer. Is it now possible to cure some patients with advanced disease? So far, we have been successful in achieving longer remissions but not cures. When I started my residency, patients with lung cancer were living 3 to 4 months and chemotherapy was experimental. Now, patients with metastatic disease live 1 year longer on average. We’re not very good yet at detecting

disease early, but we are getting better. Some of the barriers to early detection include insufficient application of smoking cessation programs and of routine screening. Just as in diseases like diabetes, you want to get good control early on in lung cancer.

E-Cigarettes A recent story in The New York Times reported on the popularity of electronic cigarettes,2 which use a nicotine solution instead of tobacco and emit a smoke-like water vapor. What is your take on e-cigarettes? I’m not in favor of e-cigarette use. We need to have more complete approaches to smoking cessation programs. I’ve seen these failures, and they don’t help people stop smoking. It is also very troubling that young people are adopting the practice of e-cigarettes because, while they may seem cool and harmless, e-cigarettes could well put people on the path to picking up a cigarette again. We know that smoking tobacco impacts on cancer survival and on second primary tumor development. It causes erratic metabolism of chemotherapy as well as increasing perioperative risk in potentially curable patients. To help patients quit smoking, oncologists need to be not just documenting smoking status, but implementing smoking cessation approaches for their patients. n Disclosure: Dr. Khuri reported no potential conflicts of interest.

Investigational ALK Inhibitor Shows Promise in Patients With Crizotinib-Refractory, ALK-Positive NSCLC

P

atients with non–small cell lung cancer (NSCLC) whose tumors have the ALK gene rearrangement usually respond to the drug crizotinib (Xalkori), with a median duration of response of approximately 10 months. In a study reported by Shirish Gadgeel, MD, of Karmanos Cancer Institute in Detroit, and colleagues at the International Association for the Study of Lung Cancer’s 15th World Conference on Lung Cancer, alectinib showed promising tumor activity in patients with ALK-positive NSCLC who were refractory to crizotinib. Alectinib is a potent ALK inhibitor recently granted Breakthrough Therapy designation by the FDA.1

had progressed on crizotinib and chemotherapy. The primary endpoint was dose-limiting toxicity, with secondary endpoints of efficacy, safety, and pharmacokinetic analyses. The ALK inhibitor was administered orally at doses ranging from 300 to 900 mg twicedaily until lack of clinical benefits. Researchers found promising tumor activity with alectinib. In the 37 patients who received a therapeutic dose (≥ 460 mg twice daily), alectinib demonstrated an overall response rate of 59.5%. Median progression-free survival had not been reached after over 5 months of follow-up. No doselimiting toxicities were observed up to the highest dose tested (900 mg twice-daily), and only one patient required dose modification due to grade 2 fatigue.

Pemetrexed Improves Progression-Free Survival vs Gefitinib in Second-Line Setting for EGFR Wild-Type Nonsquamous NSCLC

B

oth pemetrexed (Alimta) and gefitinib (Iressa) are standard second-line treatments for advanced nonsquamous non–small cell lung cancer (NSCLC) in East Asia. In a phase II trial (CTONG 0806) reported at the International Association for the Study of Lung Cancer’s 15th World Conference on Lung Cancer, Qing Zhou, MD, of Guangdong Lung Cancer Institute in China, and colleagues evaluated the efficacy of pemetrexed vs gefitinib as second-line treatment in advanced nonsquamous NSCLC with wild-type EGFR (Abstract O15.07).

Brivanib Studied in First- and Second-Line Therapy for Advanced Hepatocellular Carcinoma By Matthew Stenger

T

he investigational drug brivanib is a dual inhibitor of vascular endothelial growth factor and fibroblast growth factor signaling, both implicated in hepatocellular carcinoma. The agent was recently evaluated in two phase III trials, one comparing first-line brivanib with sorafenib (Nexavar) in advanced hepatocellular carcinoma (BRISK-FL trial) and one comparing brivanib plus best supportive care vs placebo plus best supportive care in patients with advanced hepatocellular carcinoma in whom sorafenib therapy failed or was not tolerated (BRISK-PS trial). In BRISK-FL, brivanib did not meet the criterion for noninferiority in overall survival compared with sorafenib.

BRISK-FL Trial

—Philip J. Johnson, MD, and colleagues

In the multinational phase III BRISK-FL trial, reported in the Journal of Clinical Oncology by Philip J. Johnson, MD, of the Institute of Translational Medicine, University of Liverpool, and colleagues,1 1,155 patients with advanced hepatocellular carcinoma and no prior systemic therapy were randomly assigned to oral sorafenib at 400 mg twice daily (n = 578) or oral brivanib at 800 mg once daily (n = 577). The primary endpoint was overall survival.

Study Details In total, 62% of patients were from Asia, 23% from Europe, 13% from the Americas, 0.8% from Australia, and 0.6% from Africa. The brivanib and sorafenib groups were generally well matched for age (median, 61 and 60 years), sex (84% male in both), region (eg, Asia for 60% and 64%), Eastern Cooperative Oncology Group (ECOG) performance

and 56%; liver resection in 28% and 30%, transcatheter arterial chemoembolization in 35% and 36%). A total of 1,150 patients were treated in the BRISK-FL trial (perprotocol population). At the time of the final analysis, 6% of the brivanib group and 11% of the sorafenib group remained on study. The most common reasons for study discontinuation were disease progression (46% in the brivanib group and 53% in the sorafenib group) and study drug toxicity (24% and 15%). Median duration of treatment was 3.2 months in the brivanib group and 4.1 months in the sorafenib group. Poststudy systemic treatments were received by 22% of the brivanib group and 21% of the sorafenib group, and nonsystemic treatments were received by 19% and 17%.

BRISK-FL Trial ■■ Brivanib did not meet the overall survival noninferiority criterion vs

sorafenib as first-line treatment of advanced hepatocellular carcinoma.

■■ Similar antitumor activity of the two treatments was indicated by similar time to progression and objective response rates.

■■ Brivanib had an acceptable safety profile but was less well-tolerated compared with sorafenib.

Overall Survival Noninferiority

tion (HR = 1.07, 95.8% CI = 0.94– 1.23, P = .312). Results for subgroups were consistent with those for the overall study population. On multivariate analysis, significant prognostic factors for overall survival were alpha-fetoprotein, tumor morphologic features, size of the largest nodule, Child-Pugh score, and major portal vein invasion. After adjusting for baseline factors, the effect of brivanib vs sorafenib remained unchanged (HR = 1.09, 95% CI = 0.95– 1.25).

Secondary Endpoints Median time to progression was 4.2 months in the brivanib group and 4.1 months in the sorafenib group (P = .853), objective response rate was 12% vs 9% (P = .057), and disease control rate was 66% vs 65% (P = .874). Among patients with baseline alpha-fetoprotein ≥ 200 ng/mL and at least one on-study alpha-fetoprotein assessment, alpha-fetoprotein reduction ≥ 50% from baseline was observed in 58% of brivanib patients vs 31% of sorafenib patients. Similar reductions were observed when the baseline cutoff used was the upper limit of normal or 400 ng/mL.

Adverse Events Among adverse events of any grade, hand-foot skin reaction, alopecia, rash, and pyrexia were more frequent in sorafenib patients and decreased appetite, fatigue, hypertension, nausea, vomiting, hyponatremia, headache, dysphonia, and dizziness were more frequent in brivanib patients. Diarrhea, abdominal pain, constipation, hyperbilirubinemia, elevated aspartate aminotransferase (AST), elevated alanine aminotransferase (ALT), and weight loss occurred at a similar rate in the two groups. The most frequent grade 3 or 4 adverse events were hyponatremia (23% in brivanib group vs 9% in sorafenib group), AST elevation (14% vs 17%), fatigue (15% vs 7%), hand-foot skin reaction (2% vs 15%), and hypertension (13% vs 5%). Treatment was discontinued due to adverse events in 43% of brivanib patients and 33% of sorafenib patients, with the most common reasons being fatigue (5%), hyponatremia (2%), decreased appetite (2%), hyperbilirubinemia (2%), and AST elevations (2%) in the brivanib group and hyperbilirubinemia (3%) and AST elevations (2%) in the sorafenib group. Dose reduction occurred in 49% and 50% of patients, and dose interruption occurred in 58% of both groups. The investigators concluded: “This study did not meet its primary [overall survival] objective in the first-line treatment of advanced [hepatocellular carcinoma], based on a noninferiority statistical design, but it did show similar antitumor activity for brivanib and sorafenib, based on time to progression, objective response rate, and disease control rate. Brivanib had an acceptable safety profile; however, it was less well-tolerated than sorafenib.”

BRISK-PS Trial This multinational phase III trial—the first phase III brivanib trial in patients who have already received sorafenib—enrolled 395 patients with advanced hepatocellular carcinoma whose disease progressed on/ after sorafenib or who were intolerant of sorafenib. Patients were randomly assigned (2:1) to receive oral brivanib

at 800 mg once daily plus best supportive care (n = 263) or placebo plus best supportive care (n = 132). The primary endpoint was overall survival. The study was reported in the Journal of Clinical Oncology by Josep M. Llovet, MD, of the Icahn School of Medicine at Mount Sinai in New York, and colleagues.2

Study Details Overall, 42% of patients were from Europe, 41% from Asia, and 17% from the Americas. The brivanib and placebo groups were generally well matched for age (median, 64 and 62 years), sex (82% and 86% male),

vs 18%), including portal vein invasion/ thrombosis (25% vs 12%), and a higher alpha-fetoprotein level (median, 204 vs 100 ng/mL). Study treatment was discontinued in 90% of brivanib patients and 92% of placebo patients, with the most common reasons being disease progression (50% and 70%) and study drug toxicity (23% and 7%). Median treatment duration was 3.1 months for brivanib and 2.5 months for placebo. After discontinuation of study treatment, 27% of the brivanib group and 35% of the placebo group received systemic therapies and 18% and 20% received nonsystemic treatments.

The brivanib group had more patients with vascular invasion (31%

Overall Survival Outcome Overall survival was not significantly improved in the brivanib vs placebo group (HR = 0.89, 95.8% CI = 0.69–1.15, P = .331); median overall survival was 9.4 and 8.2 months, respectively. Overall survival results across prespecified subgroups were generally consistent with the primary overall survival analysis. On multivariate analysis, alphafetoprotein (< 200 ng/mL vs ≥ 200 g/mL, P < .001) and portal vein invasion (no vs yes, P < .001) were significant prognostic factors for overall survival. After adjustment for all prespecified factors, the hazard ratio for overall survival for brivanib vs

placebo was 0.81 (P = .1044). Post hoc analyses using poststudy treatments as a time-dependent covariate did not show an impact of poststudy treatment on overall survival.

Secondary Endpoints Time to progression was significantly longer in the brivanib group (median, 4.2 vs 2.7 months, HR = 0.56, P < .001), including after adjustment for baseline prognostic factors (HR = 0.56, 95% CI = 0.42–0.76). The objective response rate was also significantly higher with brivanib treatment (10% vs 2%, odds ratio [OR] = 5.75, P = .0030), as was disease control rate (61% vs 40%, OR = 2.38, P < .001). Among patients with baseline alpha-fetoprotein greater than the upper limit of normal, a reduction of ≥ 50% from baseline occurred in 54% of brivanib patients and 7% of placebo patients.

Adverse Events Study discontinuation due to treatment-related adverse events occurred in 23% of brivanib patients and 7% of placebo patients. The most frequent treatment-related grade 3 or 4 adverse events in the brivanib group included hypertension (17% vs 2%), fatigue (13% vs 1%), hyponatremia (11% vs 2%), and decreased appetite (10% vs 2%). The most frequent grade 3 or 4 laboratory abnormalities were hyponatremia (27% vs 14%), AST increase (27% vs 24%), and hy-

perbilirubinemia (21% vs 18%). Six deaths on study were considered by investigators as possibly related to treatment, all of which were in the brivanib arm and occurred within 30 days of the final dose. Two of the deaths were a result of encephalopathy, and one each was due to liver failure, acidosis, sudden death, and coma/cerebral edema. The investigators concluded: “In patients with [hepatocellular carcinoma] who had been treated with sorafenib, brivanib did not significantly improve [overall survival]. The observed benefit in the secondary outcomes of [time to progression] and objective response rate warrants further investigation…. The results of our trial may inform the design of future studies in this patient population.” n

Brivanib Fails to Live Up to the Promise of Early Studies By Laura Williams Goff, MD, MS

H

epatocellular carcinoma is a devastating disease worldwide. Although advances in liver transplantation, surgery, and locoregional therapies have made tumor control or even cure possible for a minority of patients, the majority of patients diagnosed with hepatocellular carcinoma will develop advanced-stage disease for which systemic therapy is the only option. Unfortunately, cytotoxic chemotherapy has been largely ineffective, and the only agent shown to definitively improve survival has been sorafenib (Nexavar), which targets vascular endothelial growth factor (VEGF) among other signaling pathways.1 Still, the results are far from spectacular, with frequent intolerance to sorafenib and shortlived responses. Therefore, new treatments are desperately needed in hepatocellular carcinoma for both untreated patients as well as those with refractory disease.

Drug Development Because of the vascular nature of hepatocellular carcinoma and the efficacy of sorafenib, many of the treatments in development have focused on the VEGF pathway, its inhibitors, and its resistance pathways. Fibroblast growth factor (FGF) and its receptors have been shown to drive angiogenesis directly, as well as function as a resistance mechanism for overcoming VEGF inhibition.2,3 Brivanib is a tyrosine kinase inhibitor of both VEGF and FGF receptors and therefore a seemingly ideal candidate drug to be considered for use in hepatocellular carcinoma, either initially or in refractory disease.4 Results in preclinical models with cell lines and xenografts looked promising, and phase II studies in patients with untreated or progressive hepatocellular carcinoma after prior antiangiogenic therapy demonstrated that the majority of patients had disease Dr. Goff is Assistant Professor of Medicine, Vanderbilt-Ingram Cancer Center, Associate Program Director, Vanderbilt HematologyOncology Fellowship Program, Vanderbilt University School of Medicine, Nashville.

control with provocative survival times observed.5,6 Consequently, two large phase III studies of brivanib in hepatocellular carcinoma were launched—the BRISK-FL study in first-line therapy and the BRISK-PS study in patients whose disease progressed on or who were intolerant of sorafenib.7,8 Unfortunately, neither study met its endpoint to demonstrate activity of brivanib in hepatocellular ­carcinoma.

Key Results In the BRISK-FL study, previously untreated patients were randomly assigned in equal numbers to brivanib or sorafenib. The primary

sults were disappointing. Although there was an observed response rate of 10% using the modified RECIST criteria, overall survival was not significantly improved over treatment with placebo. Interestingly, the survival time for the group treated with placebo was significantly longer than that observed in other second-line studies, and the authors do cite an imbalance in the rate of vascular invasion in the brivanib group (31%) compared to placebo (18%) as a potential confounding factor. Still, a prespecified analysis controlling for all baseline factors failed to reach statistical significance for prolonging overall survival.

Optimizing VEGF blockade and overcoming resistance to blockade are clearly not enough to treat advanced hepatocellular carcinoma. An understanding of other drivers of hepatocellular carcinoma will be essential to improve outcomes. —Laura Williams Goff, MD, MS

endpoint was noninferiority of overall survival with brivanib compared to sorafenib. This was not demonstrated, although the numeric values were in line with previously observed median survival times (9.9 months for sorafenib and 9.5 months for brivanib). Probably more importantly, overall rates of adverse events were higher with brivanib, although hand-foot syndrome occurred less frequently with brivanib. Thus, brivanib was less tolerable and resulted in survival inferior to sorafenib, clearly disappointing and echoing the failure of sunitinib (Sutent) to improve upon standard first-line treatment with sorafenib.9 Patients who had been previously treated with sorafenib and were either intolerant of or showing disease progression on that drug were enrolled on the BRISK-PS study and randomly assigned 2:1 to brivanib or placebo. Again, the re-

Conclusions Optimizing VEGF blockade and overcoming resistance to blockade are clearly not enough to treat advanced hepatocellular carcinoma. Moving forward, an understanding of other drivers of hepatocellular carcinoma apart from the VEGF pathway that may be synergistic with antiangiogenic drugs will be essential to substantially improve outcomes for patients. The role of cytotoxic chemotherapy as potentially complementary to sorafenib is under investigation in the ongoing Cancer and Leukemia Group B (CALGB) 80802 study looking at sorafenib with or without doxorubicin. Other traditional chemotherapy regimens such as ­GEMOX (gemcitabine, oxaliplatin) and FOLFOX (leucovorin, fluorouracil, oxaliplatin) have shown interesting results. Agents such as cetuximab (Erbitux), erlotinib (Tarceva), evero-

limus (Afinitor), cabozantinib (Cometriq), tivantinib, and others that do not primarily target angiogenesis are being explored as ways to build on the benefits and limitations seen with sorafenib treatment in hepatocellular carcinoma. n Disclosure: Dr. Goff has received research funding from Bristol-Myers Squibb, OSI/ Astellas, Roche, Pfizer, Sanofi, and Amgen.

FOR OVERALL SURVIVAL LOOK TO ZELBORAF Significant improvement in overall survival (OS) demonstrated in a Phase III trial vs dacarbazine in BRAF V600E(+) patients with unresectable or metastatic melanoma*

Indication and Usage: ZELBORAF速 (vemurafenib) tablets are indicated for the treatment of patients with unresectable or metastatic melanoma with BRAF V600E mutation as detected by an FDA-approved test. ZELBORAF is not indicated for use in patients with wild-type BRAF melanoma. Important Safety Information on New Primary Malignancies Cutaneous Malignancies Cutaneous squamous cell carcinoma (cuSCC), keratoacanthoma, and melanoma occurred at a higher incidence in patients receiving ZELBORAF. The incidence of cuSCC and keratoacanthomas in the ZELBORAF arm was 24%. New primary malignant melanoma occurred in 2.1% of patients receiving ZELBORAF. Perform dermatologic evaluations prior to initiation of therapy and every 2 months while on therapy. Manage suspicious skin lesions with excision and dermatopathologic evaluation. Consider dermatologic monitoring for 6 months following discontinuation of ZELBORAF. Please see Brief Summary of Prescribing Information and next page for additional Important Safety Information.

* Trial design (N=675): patients with BRAF V600E mutation-positive unresectable stage IIIC or IV melanoma received either ZELBORAF 960 mg twice daily by mouth (n=337) or dacarbazine 1000 mg/m2 intravenously every 3 weeks (n=338) for first-line treatment. Patients were allowed to cross over from dacarbazine to ZELBORAF per recommendation from the Data and Safety Monitoring Board. Results were censored at crossover. OS and progression-free survival (PFS) were coprimary endpoints. Best overall response rate (BORR) and time to response (TTR) were secondary endpoints. There were 78 deaths and 121 deaths in the ZELBORAF and dacarbazine arms, respectively, at the time of FDA approval.1,2

56% reduction in risk of death from any cause in patients treated with ZELBORAF® (vemurafenib) tablets vs dacarbazine (HR=0.44; 95% CI, 0.33-0.59; P<0.0001) Indication and Usage ZELBORAF® (vemurafenib) tablets are indicated for the treatment of patients with unresectable or metastatic melanoma with BRAF V600E mutation as detected by an FDA-approved test. ZELBORAF is not indicated for use in patients with wild-type BRAF melanoma. Important Safety Information New Primary Malignancies (cont’d) Non-Cutaneous Squamous Cell Carcinoma Non-cutaneous squamous cell carcinomas (SCC) of the head and neck can occur in patients receiving ZELBORAF. Monitor patients receiving ZELBORAF closely for signs or symptoms of new non-cutaneous SCC. Other Malignancies ZELBORAF may promote malignancies associated with activation of RAS through mutation or other mechanisms. Monitor patients receiving ZELBORAF closely for signs or symptoms of other malignancies. Tumor Promotion in BRAF Wild-Type Melanoma In vitro experiments have demonstrated paradoxical activation of MAP-kinase signaling and increased cell proliferation in BRAF wild-type cells that are exposed to BRAF inhibitors.

Confirm evidence of BRAF V600E mutation in tumor specimens prior to initiation of ZELBORAF. Hypersensitivity and Dermatologic Reactions Anaphylaxis and other serious hypersensitivity reactions can occur during treatment and upon re-initiation of treatment with ZELBORAF. Severe hypersensitivity reactions included generalized rash and erythema or hypotension. Severe dermatologic reactions, including Stevens-Johnson syndrome and toxic epidermal necrolysis, can occur in patients receiving ZELBORAF. In patients who experience a severe hypersensitivity or dermatologic reaction, ZELBORAF treatment should be permanently discontinued. QT Prolongation Concentration-dependent QT prolongation occurred in an uncontrolled, open-label QT sub-study in previously treated patients with BRAF V600E mutation-positive metastatic melanoma. QT prolongation may lead to an increased risk of ventricular arrhythmias, including Torsade de Pointes. Do not start treatment in patients with uncorrectable electrolyte abnormalities, QTc >500 ms, or long QT syndrome, or in patients who are taking medicines known to prolong the QT interval. Evaluate ECGs before treatment with ZELBORAF, 15 days after treatment initiation, monthly during the first 3 months of treatment, and every 3 months thereafter or more often as clinically indicated. Monitor ECG and electrolytes, including potassium, magnesium, and calcium, after dose modification of ZELBORAF for QTc prolongation. Withhold ZELBORAF in patients who develop QTc >500 ms (grade 3). Upon recovery to QTc ≤500 ms (grade ≤2), restart at a reduced dose.


Significant improvement in PFS ~4-month improvement in median PFS vs dacarbazine (5.3 months vs 1.6 months; 95% CI, 4.9-6.6 months vs 1.6-1.7 months) (HR=0.26; 95% CI, 0.20-0.33; P<0.0001)

Superior response demonstrated vs dacarbazine first line2 48.4% of treatment naive patients had confirmed response (partial response + complete response) with ZELBORAF vs 5.5% with dacarbazine (95% CI, 41.6%-55.2% vs 2.8%-9.3%; P<0.001) —There were 2 complete responses (1%) and 104 partial responses (47.4%) with ZELBORAF

First postbaseline assessment

Permanently discontinue ZELBORAF treatment if the QTc interval remains >500 ms and increased >60 ms from pre-treatment values after controlling cardiac risk factors for QT prolongation (e.g., electrolyte abnormalities, congestive heart failure, and bradyarrhythmias) Hepatotoxicity Liver laboratory abnormalities can occur. Monitor transaminases, alkaline phosphatase, and bilirubin before initiation of treatment and monthly during treatment, or as clinically indicated. Manage lab abnormalities with dose reduction, treatment interruption, or treatment discontinuation. Concurrent Administration with Ipilimumab The safety and effectiveness of ZELBORAF in combination with ipilimumab have not been established. In a dose-finding trial, grade 3 increases in transaminases and bilirubin occurred in a majority of patients who received concurrent ipilimumab (3 mg/kg) and vemurafenib (960 mg bid or 720 mg bid). Photosensitivity Mild to severe photosensitivity can occur. Advise patients to avoid sun exposure and use adequate sun protection. Institute dose modifications for intolerable grade 2 or greater photosensitivity. Ophthalmologic Reactions Uveitis, blurry vision, and photophobia can occur. Treatment with steroid and mydriatic ophthalmic drops may be required to manage uveitis. Monitor patients for uveitis.

75%

of responses to ZELBORAF occurred by 1.6 months, approximately the time of the first postbaseline assessment

Embryo-Fetal Toxicity Apprise patients who are pregnant or who may become pregnant that ZELBORAF can cause fetal harm. Most Common Adverse Reactions The most common (≥30%) adverse reactions of any grade reported were arthralgia, rash, alopecia, fatigue, photosensitivity reaction, nausea, pruritus, and skin papilloma. The most common (≥5%) grade 3 adverse reactions were cuSCC and rash. In clinical studies, cuSCC was required to be reported as grade 3 per protocol.

5.4 Dermatologic Reactions Severe dermatologic reactions, including Stevens-Johnson syndrome and toxic epidermal necrolysis, can occur in patients receiving ZELBORAF. Permanently discontinue ZELBORAF in patients who experience a severe dermatologic reaction [see Adverse Reactions (6.1)]. 5.5 QT Prolongation Concentration-dependent QT prolongation occurred in an uncontrolled, open-label QT sub-study in previously treated patients with BRAF V600E mutation-positive metastatic melanoma [see Clinical Pharmacology (12.6)]. QT prolongation may lead to an increased risk of ventricular arrhythmias, including Torsade de Pointes. Do not start treatment in patients with uncorrectable electrolyte abnormalities, QTc > 500 ms, or long QT syndrome, or in patients who are taking medicinal products known to prolong the QT interval. Evaluate ECGs before treatment with ZELBORAF, 15 days after treatment initiation, monthly during the first 3 months of treatment, and every 3 months thereafter or more often as clinically indicated. Monitor ECG and electrolytes, including potassium, magnesium, and calcium, after dose modification of ZELBORAF for QTc prolongation. Withhold ZELBORAF in patients who develop QTc > 500 ms (Grade 3). Upon recovery to QTc ≤ 500 ms (Grade ≤ 2), restart at a reduced dose. Permanently discontinue ZELBORAF treatment if the QTc interval remains > 500 ms and increased > 60 ms from pre-treatment values after controlling cardiac risk factors for QT prolongation (e.g., electrolyte abnormalities, congestive heart failure, and bradyarrhythmias) [see Dosage and Administration (2.3)]. 5.6 Hepatotoxicity Liver laboratory abnormalities can occur with ZELBORAF (Table 2) [see Adverse Reactions (6.1)]. Monitor transaminases, alkaline phosphatase, and bilirubin before initiation of treatment and monthly during treatment, or as clinically indicated. Manage laboratory abnormalities with dose reduction, treatment interruption, or treatment discontinuation [see Dosage and Administration (2.3)]. Concurrent Administration with Ipilimumab The safety and effectiveness of ZELBORAF in combination with ipilimumab have not been established [see Indications and Usage (1)]. In a dose-finding trial, Grade 3 increases in transaminases and bilirubin occurred in a majority of patients who received concurrent ipilimumab (3 mg/kg) and vemurafenib (960 mg BID or 720 mg BID) [see Drug Interactions (7.3)]. 5.7 Photosensitivity Mild to severe photosensitivity can occur in patients treated with ZELBORAF [see Adverse Reactions (6.1)]. Advise patients to avoid sun exposure, wear protective clothing and use a broad spectrum UVA/UVB sunscreen and lip balm (SPF ≥ 30) when outdoors. Institute dose modifications for intolerable Grade 2 or greater photosensitivity [see Dosage and Administration (2.2)]. 5.8 Ophthalmologic Reactions Uveitis, blurry vision, and photophobia can occur in patients treated with ZELBORAF. In Trial 1, uveitis, including iritis, occurred in 2.1% (7/336) of patients receiving ZELBORAF compared to no patients in the dacarbazine arm. Treatment with steroid and mydriatic ophthalmic drops may be required to manage uveitis. Monitor patients for signs and symptoms of uveitis. 5.9 Embryo-Fetal Toxicity ZELBORAF can cause fetal harm when administered to a pregnant woman based on its mechanism of action. There are no adequate and well-controlled studies in pregnant women. If this drug is used during pregnancy or if the patient becomes pregnant while taking this drug, the patient should be apprised of the potential hazard to a fetus [see Use in Specific Populations (8.1)].

* For ALT, alkaline phosphatase, and bilirubin, there were no patients with a change to Grade 4 in either treatment arm. 7 DRUG INTERACTIONS 7.1 Effect of Strong CYP3A4 Inhibitors or Inducers on Vemurafenib Vemurafenib is a substrate of CYP3A4 based on in vitro data; therefore, coadministration of strong CYP3A4 inhibitors or inducers may alter vemurafenib concentrations [see Clinical Pharmacology (12.3)]. Avoid coadministration of ZELBORAF with strong CYP3A4 inhibitors (e.g., ketoconazole, itraconazole, clarithromycin, atazanavir, nefazodone, saquinavir, telithromycin, ritonavir, indinavir, nelfinavir, voriconazole) or strong inducers (e.g., phenytoin, carbamazepine, rifampin, rifabutin, rifapentine, phenobarbital), and replace these drugs with alternative drugs when possible. 7.2 Effect of Vemurafenib on CYP1A2 Substrates Concomitant use of ZELBORAF with drugs with a narrow therapeutic window that are predominantly metabolized by CYP1A2 is not recommended as ZELBORAF may increase concentrations of CYP1A2 substrates [see Clinical Pharmacology (12.3)]. If coadministration cannot be avoided, monitor closely for toxicities and consider a dose reduction of concomitant CYP1A2 substrates. 7.3 Ipilimumab Increases in transaminases and bilirubin occurred in a majority of patients who received concurrent ipilimumab and ZELBORAF [see Warnings and Precautions Section 5.6]. 8 USE IN SPECIFIC POPULATIONS 8.1 Pregnancy Pregnancy Category D [see Warnings and Precautions (5.9)]. ZELBORAF can cause fetal harm when administered to a pregnant woman based on its mechanism of action. Vemurafenib revealed no evidence of teratogenicity in rat embryo/ fetuses at doses up to 250 mg/kg/day (approximately 1.3 times the human clinical exposure based on AUC) or rabbit embryo/fetuses at doses up to 450 mg/kg/day (approximately 0.6 times the human clinical exposure based on AUC). Fetal drug levels were 3-5% of maternal levels, indicating that vemurafenib has the potential to be transmitted from the mother to the developing fetus. There are no adequate and well controlled studies in pregnant women. Women of childbearing potential and men should be advised to use appropriate contraceptive measures during ZELBORAF therapy and for at least 2 months after discontinuation of ZELBORAF. If this drug is used during pregnancy or if the patient becomes pregnant while taking this drug, the patient should be apprised of the potential hazard to a fetus. 8.3 Nursing Mothers It is not known whether vemurafenib is excreted in human milk. Because many drugs are excreted in human milk and because of the potential for serious adverse reactions from ZELBORAF in nursing infants, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.

8.5 Geriatric Use Clinical studies of ZELBORAF did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. 8.6 Hepatic Impairment No formal clinical study has been conducted to evaluate the effect of hepatic impairment on the pharmacokinetics of vemurafenib. No dose adjustment is recommended for patients with mild and moderate hepatic impairment based on a population pharmacokinetic analysis [see Clinical Pharmacology (12.3)]. The appropriate dose of ZELBORAF has not been established in patients with severe hepatic impairment.

with a T3151 mutation, which doesn’t respond to any other medication, I don’t know that I can get that patient ponatinib. I haven’t seen any instructions or guidance about how to get access to this medication. I know that Ariad is working very hard with the FDA to come up with a plan but I haven’t seen anything yet,” said Dr. Druker.

Adverse Events In clinical trials conducted before ponatinib’s approval, serious blood clots occurred in 8% of patients taking the drug and blood clots in the veins occurred in 3% of patients. More recent data found approximately 24% of patients in the phase II clinical trial (median treatment duration, 1.3 years) and approximately 48% of patients in the phase I clinical trial (median duration, 2.7 years) experienced serious adverse vascular events. The events included life-threatening heart attack, stroke, loss of blood flow to the extremities resulting in tissue death, and severe narrowing of blood vessels in the extremities, heart, and brain requiring urgent surgical procedures to restore blood flow. “We clearly have to take the FDA review quite seriously,” said Dr. Druker. “[But] I have to say that I have lots of patients who are doing extremely well on [ponatinib]. They had no other treatment options. I hope that we will be able to continue to treat them and should be able to treat other patients in a similar circumstance who have no other decent treatment options.” n

Inside the Black Box Neoadjuvant Treatment of Early Breast Cancer A Conversation With FDA’s Office of Hematology and Oncology Products INSIDE THE BLACK BOX is an occasional column providing insight into the FDA and its policies and procedures. In this first installment, FDA Clinical Reviewers Laleh Amiri-Kordestani, MD, and Suparna Wedam, MD, discuss FDA’s recent approval of pertuzumab (Perjeta) for the neoadjuvant treatment of HER2-positive, high-risk early breast cancer. Dr. Amiri and Dr. Wedam are Medical Officers with the Breast/Gynecologic Cancer Team in the Office of Hematology and Oncology Products.

tient level, but not at a trial level. However, this analysis does not preclude the use of pathologic complete response to support an accelerated approval, because the effect sizes in the trials used in the analysis were relatively small. Once accelerated approval is granted based on pathologic complete response, confirmation of clinical benefit (eg, improvement in event-free, disease-free, or overall survival) is required in order to convert to a regular approval.

Surrogate Endpoint

O

n September 30, 2013, the U.S. Food and Drug Administration (FDA) granted accelerated approval to pertuzumab (Perjeta) for the neoadjuvant treatment of HER2-positive highrisk early breast cancer. Here Dr. Amiri and Dr. Wedam respond to questions about the processes leading to pertuzumab’s accelerated approval.

Evaluating Neoadjuvant Therapy What is the rationale for neoadjuvant therapy for breast cancer? Dr. Amiri: Neoadjuvant therapy for breast cancer was first developed to help make inoperable tumors operable and to increase the rate of breast conservation. Also, neoadjuvant trials provide a unique opportunity to study modulation of tumor biomarkers and have the potential to guide and improve the design of adjuvant trials. Regimens that are given in the adjuvant setting are commonly used in the neoadjuvant setting, knowing that survival is similar whether chemotherapy is given before or after surgery.1 From a drug development perspective, using pathologic complete response rate as the primary endpoint is very appealing since it can be assessed relatively quickly. Please explain the FDA’s view on evaluating new drugs in the neoadjuvant setting. Why is the agency interested in this? Dr. Wedam: Typically, drug development is a lengthy and expensive process. Demonstration of an improvement in disease-free survival or overall survival for a new treatment for patients with early breast cancer in the adjuvant

setting requires a large trial that takes many years to complete. Thus, pharmaceutical companies first test drugs in the metastatic setting, where endpoints can be obtained faster. Despite many recent approvals in the treatment of metastatic breast cancer, the process of drug development for patients with early breast cancer— especially for high-risk or poor prognosis populations—has been slow. In the past decade, only one drug has been approved for this early breast cancer high-risk population.2 What is the FDA doing to help facilitate this process? Dr. Amiri: FDA’s accelerated approval regulations are intended to facilitate availability of drugs for treatment of a serious or life-threatening disease that provide meaningful therapeutic benefit over available therapy.3 The agency would like to expedite the process and help patients with high-risk early breast cancer gain access to promising new agents earlier.4 To help facilitate the neoadjuvant drug development pathway, the FDA has released a draft guidance titled, “Guidance for Industry Pathologic Complete Response in Neoadjuvant Treatment of High Risk Early-Stage Breast Cancer: Use as an Endpoint to Support Accelerated Approval.”5 With the collaboration of many international groups, FDA conducted a pooled-analysis of many neoadjuvant breast cancer trials.6 Pathologic complete response was shown to correlate well with long-term outcome at a pa-

The FDA facilitated a transparent, open discussion about using pathologic complete response as a surrogate endpoint to support accelerated approval for neoadjuvant treatment of early breast cancer. Can you tell us more about that? Dr. Wedam: Since this is a new pathway, we felt it was important to have as much public dialogue as possible before finalizing the Guidance. FDA in conjunction with ASCO held a workshop in March 2013 to discuss drug development for neoadjuvant treatment of breast cancer. We had a group of experts discuss issues regarding neoadjuvant therapy and the use of pathologic complete response as a surrogate endpoint. Ultimately, the experts felt that pathologic complete response was reasonably likely to predict clinical benefit and could be used to support accelerated approval of neoadjuvant therapy for use in patients with early breast cancer at high risk of relapse or death despite the best available therapies.

Key Studies Can you describe the neoadjuvant studies that were submitted to support the pertuzumab approval? Dr. Amiri: The main trial was NEOSPHERE, a randomized, multicenter, open-label trial of 417 patients with HER2-positive, operable, locally advanced, or inflammatory breast cancer who were randomly allocated to receive one of four neoadjuvant regimens prior to surgery as follows: trastuzumab (Herceptin) plus docetaxel; pertuzumab plus trastuzumab and docetaxel; pertuzumab plus trastuzumab; or pertuzumab plus docetaxel. Following surgery all patients received

three cycles of fluorouracil, epirubicin, and cyclophosphamide (FEC) intravenously every 3 weeks, and trastuzumab was administered intravenously every 3 weeks to complete 1 year of therapy. The study’s primary endpoint was pathologic complete response rate, defined as the absence of invasive cancer in the breast (ypT0/is). An additional neoadjuvant phase II trial (TRYPHAENA) was conducted in 225 patients with HER2-positive, locally advanced, operable, or inflammatory breast cancer and was designed primarily to assess the cardiac safety of pertuzumab in different neoadjuvant regimens. Patients were randomly allocated to receive one of three neoadjuvant regimens prior to surgery as follows: three cycles of FEC followed by three cycles of docetaxel, all in combination with pertuzumab and trastuzumab; three cycles of FEC alone followed by three cycles of docetaxel and trastuzumab in combination with pertuzumab; or six cycles of docetaxel, carboplatin, and trastuzumab (TCH) in combination with pertuzumab. Following surgery all patients received continued on page 50

trastuzumab intravenously every 3 weeks to complete 1 year of therapy.

ODAC Meeting The FDA recently called a meeting of the Oncologic Drugs Advisory Committee (ODAC) to discuss pertuzumab’s use in the neoadjuvant setting. What were the main points of discussion raised by the ODAC? Dr. Wedam: Several concerns with the application already apparent to us were raised during the ODAC discussion. These concerns included the uncertainty about whether an improvement in pathologic complete response rate would translate into long-term clinical benefit, the appropriate chemotherapy regimen to use with this targeted therapy, the appropriate duration of pertuzumab treatment, and the sequencing of chemotherapy. Additional concerns included an increased rate of cardiac toxicity with pertuzu­mab, the small size of the NEOSPHERE trial, the lack of patients from the United States, the lack of blinded pathology review, and the lack of prespecified pathology guidelines. In the end, ODAC voted 13 to 0 with 1 abstention that pertuzumab has demonstrated a favorable risk-benefit profile for this indication. However, many members of the committee agreed with us that this should not be considered a precedent for approval of neoadjuvant treatments, but should be viewed instead as a unique situation due to the robust overall supportive data for pertuzu­mab. These supportive data included a statistically significant and clinically meaningful improvement in overall survival from the metastatic breast cancer trial (CLEOPATRA) and extensive safety data with over 10,000 patients exposed to the drug at this time. Committee members also stated that completion of enrollment to the confirmatory adjuvant trial (APHINITY) increased their level of comfort with an accelerated approval.

Further Concerns Several ODAC members expressed concern about how pertuzumab would be used in clinical practice, particularly since in the two neoadjuvant trials, pertuzu­ mab was not given with the chemotherapy regimens commonly used in the United States. Is the FDA also concerned?

Dr. Amiri: Yes, we expressed our concern with the chemotherapy regimens, at the ODAC meeting. This was a concern we also had from the beginning. The backbone chemotherapy regimen used in the main study (NEOSPHERE) is seldom used in the United States. In addition, the splitting of the chemotherapy regimen before and after surgery is not typically done when neoadjuvant therapy is given. The chemotherapy regimens in the supportive study (TRYPHAENA) were administered entirely prior to surgery; however, two of the treatment arms included FEC, which again

thracycline regimens. Both of these trials will offer more information regarding the safety, optimal treatment regimens, and duration of treatment with pertuzumab.

Labeling Decision How did you make the final decision regarding labeling given the concerns of the applicability of the chemotherapy regimens used in the trials? Dr. Amiri: We chose to include the neoadjuvant regimens from the main experimental arm in NEOSPHERE and two of the treatment regimens from TRYPHAENA. The treatment

significant improvement in pathologic complete response rate of 17.8% (P = .0063) was observed in patients receiving pertuzumab plus trastuzumab and docetaxel compared to patients receiving trastuzumab plus docetaxel. Supportive evidence of unprecedented efficacy in the metastatic setting demonstrates that pertuzumab is an active drug that could potentially contribute to treatment regimens intended to cure a larger number of women with HER2-positive early-stage breast cancer. In addition, there are extensive safety data and the confirmatory adjuvant trial has fully accrued. This totality of evidence and status of the confirmatory trial are what we will be using to evaluate future applications that seek to use this approach for accelerated approval. n

is not commonly used in the United States. The third treatment arm in TRYPHAENA combined pertuzumab with the nonanthracycline regimen TCH, an FDA-approved regimen in widespread use in the United States. What is the agency doing to address these concerns? Dr. Wedam: In order to address these concerns, we asked the applicant to conduct a new trial as a postmarketing requirement, investigating the combination of pertuzumab with two different anthracycline-based treatment regimens in the neoadjuvant setting. The first arm is similar to the concurrent anthracycline (FEC) treatment arm in TRYPHAENA. This regimen would provide a treatment option for physicians who choose to use an anthracycline-based regimen but also would like to get HER2-targeted therapy started quickly. The second arm will include dosedense doxorubicin/cyclophosphamide followed by weekly paclitaxel (ddAC-T) with trastuzumab and pertuzumab. The ddAC-T regimen is widely used in the United States. Both treatment arms would continue trastuzumab and pertuzumab for 1 full year. Additional information will be obtained from the fully accrued adjuvant trial (APHINITY), which includes anthracycline and nonan-

regimen from NEOSPHERE isolates the effect of pertuzumab. The two treatment regimens from TRYPHAENA include TCH, which is an approved adjuvant regimen in the United States, and the sequential anthracycline (FEC) followed by docetaxel, trastuzumab, and pertuzumab regimen. The third regimen in the TRYPHAENA trial is not recommended because there are insufficient cardiac safety data to recommend concomitant administration of an anthracycline with pertuzumab at this time. Importantly, two limitations of use were added to the label. These include the statements that safety has not been established with pertuzumab in combination with a doxorubicincontaining chemotherapy regimen and that safety of pertuzumab administration for more than six cycles in early-stage breast cancer has not been established. 7

Final Approval Why did the FDA ultimately decide to approve pertuzumab for neoadjuvant treatment of early breast cancer? Dr. Wedam: The totality of evidence—not just the magnitude of improvement in pathologic complete response rate—led us to approve pertuzumab for the neoadjuvant indication. In the main neoadjuvant study, NEOSPHERE, a statistically

interpretation on SUV calculations), and a lack of standardization—have made the application of PET scanning in the care of lymphoma patients less than perfect.

Lessons of the INR and PT On a recent trip to New York, one of our mothers needed an international normalization ratio (INR) for monitoring anticoagulation with warfarin. The practice of calculating the INR was introduced in the 1980s in an effort to standardize the prothrombin time (PT), which can be extremely variable as measured at different laboratories. The INR method offers a consistent result and enabled this woman’s primary care physician to balance her risk of clotting and bleeding despite being a time zone away. This is a routine experience, and clinicians have grown accustomed to ignoring the location of where a prothrombin time was performed and only paying attention to the INR. You might ask, how can we learn anything regarding lymphoma from the history of the development of the INR and its necessary but forgotten partner, the PT? Well, just go with it, and keep reading. Over the past decade, experts in the fields of radiology, nuclear medicine, and hematologic oncology have been meeting and formalizing experiences and/or studies in an attempt to standardize response evaluations in treated lymphoma patients using PET/CT. A lot has changed in a decade. We need a control not unlike what the INR does

for the PT, so that we are all speaking the same language regardless of what time zone we’re in.

Deauville Score To try to improve comparisons among different machines and centers, and to standardize the interpretation of response to PET scans in the same way that the INR has standardized the interpretation of PT measurements, a

liver. A score of 2 indicates uptake but at a lower value than in the mediastinal blood pool, 3 denotes uptake with an intensity between the mediastinal blood pool and liver, and 4 would be an uptake greater than in the liver. A score of 5 means a dramatic increase in uptake and/or new sites of involvement. Using this method, a Deauville score of 1 or 2 is accepted as a complete response to treatment and, especially for

group of investigators met in Deauville, France, in 2009 and proposed a new approach. The Deauville score grades a scan from 1 to 5, with the score of 1 meaning no uptake consistent with lymphoma. All other scores are in relation to background uptake that is always present in the mediastinal blood pool and liver (see Table 1). Uptake in the mediastinal blood pool is consistently lower than in the

interim scans, a score of 3 is also often taken as a complete response. The beauty of the Deauville score is that we are our own control. The mediastinal blood pool SUV and liver SUV are relatively fixed values but could vary significantly between patients—not unlike how the PT can vary between hospitals as a result of heterogeneous reagents. The Deauville score also allows for premeditated risk stratification based on the objectives of using PET/CT. Excellent examples of this approach include scenarios in early- and advanced-stage lymphoma: If the strategy is to test escalation of therapy based on interim PET/CT, it might be prudent to use a higher SUV cutpoint (ie, Deauville 3), which could reduce the number of unnecessary and potentially more risky therapeutic escalations. If testing to discontinue or reduce therapy, we should again be prudent, and

a Deauville 2 cutpoint may be considered. This is where strategies based on changes in SUV may falter and lack global acceptance despite persuasive prognostic arguments.

Conclusions and Caveats We are heading in the right direction with appropriate PET/CT evaluation in currently accruing or accrued clinical trials, but outside of a clinical trial, far too many PET/CT results lack reporting of the mediastinal blood pool or liver SUVs. The ordering physician is often responsible for this lack of reporting, having failed to provide the radiologist or nuclear medicine physician with adequate information to acknowledge that this is a staging, interim, or post-treatment PET/CT. As a result, an SUV of 3.2 can leave the oncologist scratching his head and dreading the conversation with the patient that will often ensue. We should be asking for the anatomic control SUVs, not persuading a colleague to provide a second opinion for reassurance. The Deauville score offers oncologists the opportunity to confidently use the PET scan to determine a patient’s response to chemotherapy for lymphoma. However, there are some caveats. For example, the best response to chemotherapy can be determined more quickly than the best response to radiotherapy, where it can sometimes take 2 or 3 months to see a complete response. Even so, the Deauville score represents a significant advance in interpreting response to therapy for patients treated with chemotherapy for lymphoma. It should become a standard approach for oncologists who care for these patients. n

IOM Report

Framework for Change

continued from page 1

The IOM report puts forth a conceptual framework, or blueprint, for a strategic approach to change, at the core of which is the delivery of comprehensive, patient-centered, evidence-based, high-quality care that is accessible and affordable to all U.S. patients. The IOM’s conceptual framework leads to 10 specific goals and their associated recommendations: 1. Provide patients and family members with understandable information at key decision points on such matters as cancer prognosis, treatment benefits and harms, palliative care, psychosocial support, and costs. 2. Provide patients with end-of-life care that is consistent with their needs, values, and preferences. 3. Provide patients with high-quality cancer care that is delivered by a diverse team of professionals to ensure coordinated and comprehensive patient-centered care. 4. Require cancer care teams to have the necessary skills through training, certification, and credentials to de-

multidisciplinary IOM committee that wrote the report. Dr. Ganz is Distinguished University Professor, University of California, Los Angeles Schools of Medicine and Public Health, and Director, Cancer Prevention & Control Research, Jonsson Comprehensive Cancer Center. “Now we have the advances from the Human Genome Project and we know that breast cancer is not 2 or 3 diseases—it is 10 diseases, and lung cancer may be 15 different diseases,” she said. “We have very expensive diagnostic tests that we have to apply to every tumor in order to find the few that have specific treatable mutations,” Dr. Ganz continued. “We have targeted therapies that are very useful but are very expensive. The ability to deliver high-quality evidence-based care has been accelerated, but we have the aging of the population and looming workforce shortages placing great potential stress on the system.”

10. Improve the affordability of cancer care by leveraging existing efforts to eliminate, e.g., choosing wisely, as well as reform payment strategy and reforms fee-for-service reimbursements to new payment models and eliminates duplications of services.

Tailored Care “What we have done in developing this conceptual framework for a highquality cancer care delivery system is put the patient and patient-clinician interactions at the center. Cancer care needs to be tailored to every patient’s needs, and communication is central to that effort,” said Dr. Ganz. To ensure quality care, patients need to understand their diagnosis, prognosis, and treatment plan—which should include palliative care to alleviate symptoms such as pain, fatigue, and insomnia, and psychosocial support across the treatment continuum—and make their preferences known, according to Dr. Ganz. To accomplish the development of a higher-quality cancer care deliv-

Rising Numbers The numbers cited in the report tell the story of why the country’s cancer care system is in such a perilous state and likely to become worse unless a new approach is taken. According to the report, approximately 14 million Americans are survivors after a cancer diagnosis more than 1.6 million new cases are diagnosed each year. By 2022, the number of U.S. cancer survivors is expected to grow to 18 million and by 2030 cancer incidence is projected to climb to 2.3 million. In addition, the number of older Americans is predicted to double between 2010 and 2030, contributing to a projected 30% rise in the number of cancer survivors from 2012 to 2022, and a 45% increase in cancer incidence by 2030. The cost of cancer care, which is escalating faster than other sectors of medicine, is also soaring and expected to rise from $125 billion in 2010—up from $72 billion in 2004—to $173 billon by 2020. The rising costs are making care less affordable, according to the report, and creating disparities in patients’ access to high-quality cancer care. The increasing numbers of patients with cancer coupled with escalating costs to care for them is also resulting in a workforce shortage of oncology care professionals.

liver high-quality care. 5. Provide evidence-based care by expanding the breadth of data collected in clinical trials through the enrollment of older adults and patients with comorbidities. 6. Expand the depth of data collected in clinical research through patientreported outcomes, patient characteristics, and health behaviors. 7. Implement health-care learning and information technology, such as ASCO’s CancerLinQ™, that enables real-time analysis of data from cancer patients to inform medical decisions. 8. Develop a national quality-reporting program for cancer care. 9. Develop a national strategy to reduce disparities in accessing cancer care, especially in underserved populations that leverages existing community interventions to improve access to affordable cancer care.

ery system, the IOM authors urge all stakeholders, including medical teams, patients and their families, researchers, payers, industry, and federal agencies to work together toward a shared goal of improving the quality of life and outcomes for people diagnosed with cancer.

ASCO Commends Report ASCO was among the 13 study sponsors of the IOM report. The Society applauded the recommendations by the committee members. “Every person with cancer should receive state-of-the-art, high-quality, and compassionate care,” said ASCO President Clifford A. Hudis, MD, FACP. “The IOM’s recommendations offer a solid framework for achieving that goal by helping us improve the quality of care today while developing evidence for safe and effective treat-

ments for tomorrow.” His statement continued: For oncologists, continuously improving the quality of cancer care is at the core of our mission. This report provides important strategies we can use now to reach this goal and ASCO already has efforts in place that will advance many of the IOM’s recommendations. The Society’s Quality Oncology Practice Initiative (QOPI®) … is the first, national program to help practices improve the quality of care they deliver. In 2011, ASCO issued recommendations to improve physicianpatient communication regarding the full range of care options for patients with advanced cancer. And now, ASCO’s Institute for Quality is developing CancerLinQ™, a groundbreaking effort to achieve the IOM’s vision of a learning health system that will revolutionize cancer care and achieve better outcomes for patients. We commend the IOM for this landmark report and will work with policymakers, patients, health IT groups, and the oncology community to implement its recommendations.

Future of Cancer Care Despite the challenges ahead, Dr. Ganz is optimistic that the goals set forth in the IOM report will result in higher quality of care for patients and a more accessible health-care system. “With every crisis, there is tremendous opportunity for growth, and I think for most of our recommendations, various stakeholders are already working on achieving these goals,” said Dr. Ganz. “What we are really saying is that this is a blueprint—a plan to give us focus—and one that we can all rally around.” n

Technologic Innovations Are Likely to Transform Oncology Care By Susan London

O

ncology and medicine as a whole are likely to benefit from a variety of technologic innovations recently showcased at the third annual The Atlantic Meets the Pacific symposium, according to Peter P. Yu, MD, PresidentElect of the American Society of Clinical Oncology, and medical oncologist and Director of Cancer Research at the Palo

Alto Medical Foundation, Mountain View and Sunnyvale, California. The symposium—a joint collaboration of The Atlantic magazine and the University of California, San Diego— brings together top thought leaders in technology, the sciences, and health to discuss innovations in these fields and issues surrounding their implementation in real-world practice. It features one-on-one interviews, panel discussions, and laboratory tours. More than 300 scientists, engineers, physicians, software developers, venture capitalists, and patient advocates attended this year’s event. “Personally, I found the symposium valuable because of the exposure to people who are in the cancer space but are not physicians.… For the most part, they appear to be highly intelligent and knowledgeable about the field,” Dr. Yu commented in an interview. “I found it a validation of what we [oncologists] are thinking and doing … in the sense that it isn’t going to be as hard to explain to someone what we are doing because they are already wondering about the same questions. They don’t necessarily have our degree of insight into cancer or the possible solutions, but they understand the issues in a broad sense. So that means we can engage these folks more readily.”

Harnessing Big Data A major symposium theme was harnessing big data—the mining of vast amounts of information to solve problems and ultimately improve outcomes. “I heard a lot of generalities in

terms of molecular medicine, precision medicine, and drugs and diseases.… People have a better sense of what that means than they did, say, 5 years ago,” Dr. Yu commented. “But big data is where we were with

molecular medicine 10 year ago, where we believed in it, we could see it, but it wasn’t tangible—patients weren’t living decades longer because of that,” he continued. “So the big data people are still not sure they have their hands

around it. That makes it positive for us with CancerLinQ, because if we can offer something that’s more tangible, people will gravitate toward that.” Symposium presenters discussed continued on page 56

a variety of novel technologies that are poised to change the clinician and patient experience. “The technologies seemed to be unified by a single concept, which is unleashing the information that’s already known somewhere and bringing it to bear at

the time when it’s most relevant,” Dr. Yu observed. Examples included use of Google Glass during medical visits to streamline accessing of online information, and programs that crunch patient data to anticipate complications after chemotherapy or surgery and preemptively send out queries to patients.

Cost Issues Inevitably, a key issue attendees broached was the cost of these advances. “It may be great and cool and wonderful, but can we afford it?” Dr. Yu commented. “The answer is, we can afford it if it improves outcomes sufficiently to justify it and/or if it saves money immediately because it eliminates a problem

that we would have to spend even more money on if we don’t do this right. And it has to be now—it can’t be, well, we do this now, and 10 years from now we’ll reap the savings, because no one’s going to pay for that,” he said. “There’s a sense of energy, a sense that we need to move faster, that the world wants more from us, more quickly—and that we have to look hard at what we’re doing because we are not doing it fast enough and we’re not doing it affordably enough,” he said, summing up the atmosphere at the ­symposium.

Inevitable Tradeoff However, Dr. Yu acknowledged, “there’s something that’s lost by moving away from a very slow, methodical approach.… The concern I’ve heard from some oncologists is that if we only look for the big leaps forward, we will inadvertently miss the small—but what turn out to be very important— new drug or new therapy that maybe in a different setting would have proven to be a blockbuster, but in the setting we studied it in was only a small step forward. There is that risk, and I don’t think there is any way to get around it…. That’s a tradeoff that we have to decide about.” n Disclosure: Dr. Yu reported no potential conflicts of interest.

No Difference in Long-Term Survival With Finasteride or Placebo in the Prostate Cancer Prevention Trial By Matthew Stenger

I

n the Prostate Cancer Prevention Trial (PCPT), initially reported in 2003, finasteride significantly reduced the risk of prostate cancer by 24.8% but was associated with a relative 26.9% increase in risk of high-grade disease compared with placebo. In a study reported in The New England Journal of Medicine, Ian M. Thompson, MD, of The University of Texas Health Science Center at San Antonio, and colleagues analyzed survival rates of all subjects and those with prostate cancer in the trial during up to 18 years of follow-up.1 They found that although high-grade cancer was more common in the finasteride group, there were no significant differences between the finasteride and placebo groups in rates of overall survival or survival after diagnosis of prostate cancer.

prostate cancer prevention. In the current study, investigators analyzed survival in the two study groups at 18 years after initial randomization to identify evidence of increased risk of death in the finasteride group, since such an increase might be an indicator of increased risk of highgrade cancer. Data on the incidence of

Finasteride reduced the risk of prostate cancer by about one third. High-grade prostate cancer was more common in the finasteride group than in the placebo group, but after 18 years of follow-up, there was no significant between-group difference in the rates of overall survival or survival after the diagnosis of prostate cancer.

Study Details Analyses of the PCPT have indicated that the use of finasteride improved the sensitivity of prostate-specific antigen (PSA) testing, prostate biopsy, and digital rectal examination for identification of prostate cancer and improved the sensitivity of PSA testing and prostate biopsy for detection of high-grade disease. The improved sensitivity may have reflected reduction of PSA in finasteride recipients who had benign enlargement and subsequent shrinkage of the prostate. Although analyses suggested that such detection bias accounted for at least some of the greater rate of high-grade tumors in the finasteride group, concern over the potential risk with finasteride has resulted in virtual abandonment of its use in

Risk of low-grade cancer was reduced in the finasteride group (RR = 0.57, P < .001). In the primary 2003 report, rela-

tive risks were 0.75 (P < .001) for any cancer, 0.62 (P < .001) for low-grade cancer, and 1.27 (P = .005) for highgrade cancer.

Survival Outcomes At the time of randomization, the median age of participants was 63 years. As of October 31, 2011, the median age of those still alive was 79 years. Median age at the time of prostate cancer diagnosis was 70 years in the two groups. The 15-year survival rate was 78.0% in the finasteride group and 78.2% in the placebo group (unadjusted hazard ratio [HR] 1.02, P = .46; HR adjusted for age, race, and prostate cancer diagnosis 1.03, P = .26). Factors significantly associated with death from any cause were age at randomization (HR = 1.12 as continuous variable, P < .001) and black vs non-black race (HR = 1.48, P < .001). Among men with prostate cancer, the unadjusted hazard ratio for

death in the finasteride group was 1.01 (P = .90) and the hazard ratio adjusted for cancer grade, age at diagnosis, race, and family history of prostate cancer was 0.93 (P = .45). At 10 years, survival rates for men with prostate cancer were 79.3% in the finasteride group and 79.5% in the placebo group, including rates of 83.0% vs 80.9% in those with low-grade cancer and 73.0% vs 73.6% in those with high-grade cancer. Compared with patients with highgrade cancer in the finasteride group, patients with low-grade cancer and placebo recipients were less likely to die. Hazard ratios for death after diagnosis were 0.64 (P = .001) for finasteride patients with low-grade cancer, 0.94 (P = .68) for placebo patients with high-grade cancer, and 0.73 (P = .01) for placebo patients with low-grade cancer. Age at diagnosis was a significant predictor of death after diagnosis (HR = 1.11, P < .001). Limitation of the survival analysis to patients diagnosed with prostate cancer at the time of the initial report did not change the results. The test for interaction between treatment and cancer grade was not significant (P = .32), indicating that the betweengroup difference in risk of death from high-grade cancer was not significant. The investigators concluded, “Finasteride reduced the risk of prostate cancer by about one third. High-grade prostate cancer was more common in the finasteride group than in the placebo group, but after 18 years of followup, there was no significant betweengroup difference in the rates of overall survival or survival after the diagnosis of prostate cancer.” n

Finasteride for Prostate Cancer Prevention: LongTerm Results Disappointing but Reassuring By Michael L. LeFevre, MD, MSPH

A

ll medical care should seek to achieve one or more of three goals: to relieve suffering, to prevent future suffering, or to prolong life. Care for cancer is no exception, and minimizing suffering from cancer and prolonging life has primarily resulted from advances in treatment. Although there are a few notable exceptions, neither primary nor secondary prevention (screening) has had much impact on the morbidity and mortality of cancer.

Screening Efforts Prostate cancer is a logical target for a preventive service, and one of the few cancers for which both primary and secondary prevention seems attainable. However, results from screening efforts have been disappointing. The multicenter Prostate, Lung, Colorectal and Ovarian Cancer Screening Trial1 conducted in the United States showed a non–statistically significant increase in prostate cancer mortality, though the European Randomized Study of Screening for Prostate Cancer (ERSPC) trial2 showed a statistically significant absolute reduction of 0.10 prostate cancer deaths per 1,000 person-years after a median follow-up of 11 years. All-cause mortality was 19.1% in the screened group and 19.3% in the control group—a difference that was not statistically significant. Much of the morbidity resulting from prostate cancer is a consequence of the diagnosis and management of the disease, rather than the disease itself. Unfortunately, the small reduction in prostate cancer mortality that was seen in the ERSPC occurred in Dr. LeFevre is Future of Family Medicine Professor and Vice Chair, Department of Family and Community Medicine, University of Missouri, Columbia.

the context of a significant increase in the number of cancers diagnosed and treated in the screened group.

Primary Prevention Safe and effective primary prevention of any cancer has much appeal. The Prostate Cancer Prevention Trial (PCPT)3 was a landmark study that sought to reduce the morbidity and mortality of prostate cancer by use of finasteride to prevent development of

bias, then one would have anticipated a higher rate of mortality in the finasteride group. In this regard, the results were reassuring, with an overall 15-year mortality rate of 22% in the finasteride group and 21.8% in the control group. The investigators were unable to report prostate cancer-specific mortality, and as noted in the results of the ERSPC above, a small difference in prostate cancer mortality can exist in the absence of a difference in all-

the disease—ie, primary prevention. Men in both the finasteride and placebo groups were regularly screened for prostate cancer. Previously published results from this trial showed that the risk of prostate cancer in the finasteride group was 24.8% lower than the placebo group, but the risk of high-grade cancer was 26.9% higher. Several biases have been identified to explain the increase in high-grade cancers,4 but concern for harm remained. In addition, the impact of the reduction in the overall incidence of prostate cancer on morbidity and mortality was uncertain. Thompson et al recently reported long-term all-cause mortality in study participants,5 and the results were both reassuring and disappointing. If the increase in high-grade cancers had been real rather than the result of diagnostic

cause mortality. On the other hand, the large overall reduction in prostate cancer incidence should have resulted in a reduction in mortality if these cancers were indeed a significant threat to the health of those diagnosed. In this regard the results were disappointing.

Conclusions Is there a role for finasteride in the primary prevention of prostate cancer? The safest conclusion is that it has no short- or long-term effect on all-cause mortality; we cannot recommend its use to prolong life. However, one of the major problems with efforts to screen for prostate cancer is overdiagnosis, the diagnosis and treatment of cancers that would never become apparent in the lifetime of the patient in the absence of screening. In a population of men being

actively screened for prostate cancer, finasteride does appear to reduce the likelihood of the diagnosis of cancer, and thus reduce the harm associated with overdiagnosis and overtreatment. This reduction has no impact on all-cause mortality. Whether it has either a positive or negative effect on prostate cancer-specific mortality remains unknown, but either way, the effect is likely very small. A safe and effective approach to both primary and secondary prevention of prostate cancer remains elusive. Screening has at most a small benefit and significant harm. Primary prevention with finasteride likely has no significant impact on mortality, but may reduce the iatrogenic harm that results from screening. We all hope science will move us forward in both areas. n Disclosure: Dr. LeFevre reported no potential conflicts of interest.

FDA Announces Strategic Plan to Prevent Drug Shortages

T

he U.S. Food and Drug Administration (FDA) is taking two actions to further enhance the agency’s ongoing efforts to prevent and resolve drug shortages.. The FDA has released a strategic plan called for in the Food and Drug Administration Safety and Innovation Act (FDASIA) of 2012 to improve the agency’s response to imminent or existing shortages, and for longer term approaches for addressing the underlying causes of drug shortages. The plan also highlights opportunities for drug manufacturers and others to prevent drug shortages by promoting and sustaining quality manufacturing.

turing metrics to assist in the evaluation of manufacturing quality, as well as incentives for high-quality manufacturing; internal organization improvements to focus on quality; and risk-based approaches to identify early warning signals for manufacturing and quality problems.

Early Notification Early notification gives the FDA time to work with manufacturers to investigate the issue leading to the manufacturing disruption, identify other manufacturers who can make up all or part of the shortfall, and expedite inspections and reviews of submissions from manufacturers of drugs that may

The complex issue of drug shortages continues to be a high priority for the FDA, and early notification is a critical tool that helps mitigate or prevent looming shortages. —Janet Woodcock, MD

Second, the FDA issued a proposed rule requiring all manufacturers of certain medically important prescription drugs and biologic products to notify the FDA of a permanent discontinuance or a temporary interruption of manufacturing likely to disrupt their supply. The proposed rule implements the expanded early notification requirements included in FDASIA.

Strategic Plan The strategic plan, which was required by FDASIA and has been sent to Congress, describes actions the FDA will undertake to improve its current efforts to respond to early notifications of a potential shortage. These include improving the FDA’s communications about shortages, clarifying manufacturers’ roles and responsibilities by encouraging them to engage in certain practices that will reduce the likelihood of a shortage, updating the FDA’s internal procedures for responding to early notifications of potential shortages. The plan also describes efforts the FDA is considering to address the manufacturing and quality issues that are most often the root cause of drug shortages. These include broader use of manufac-

prevent or mitigate a shortage. Early notification from manufacturers about possible shortages, as required by FDASIA, has enabled the FDA to work with manufacturers to restore production of many lifesaving therapies. Since the Executive Order, there has been a 6-fold increase in notifications to the FDA. The notifications received under the existing requirements have resulted in real progress in addressing shortages. The FDA helped prevent 195 drug shortages in 2011 and 282 drug shortages in 2012, leading to a reduced number of new shortages in 2012. The expanded early notification requirements would further enhance the FDA’s ability to address issues prior to the occurrence of a shortage. “The complex issue of drug shortages continues to be a high priority for the FDA, and early notification is a critical tool that helps mitigate or prevent looming shortages,” said Janet Woodcock, MD, Director of the FDA’s Center for Drug Evaluation and Research (CDER). “The FDA continues to take all steps it can within its authority, but the FDA alone cannot solve shortages. Success depends upon a commitment from all stakeholders.” n

Pertuzumab in Neoadjuvant Treatment of HER2-Positive Early Breast Cancer By Matthew Stenger

In the Clinic provides overviews of novel oncology agents, addressing indications, mechanisms, administration recommendations, safety profiles, and other essential information needed for the appropriate clinical use of these drugs.

Indication On September 30, 2013, pertuzumab injection (Perjeta) was granted accelerated approval for use in combination with trastuzumab (Herceptin) and docetaxel for neoadjuvant treatment of patients with HER2positive locally advanced, inflammatory, or early-stage breast cancer (either > 2 cm in diameter or nodepositive) as part of a complete treatment regimen for early breast cancer.1 The accelerated approval is based on demonstration of an improvement in pathologic complete response rate. No data are yet available showing improved event-free survival or overall survival. Continued approval for this indication is contingent upon demonstration of improvement in diseasefree survival in a confirmatory trial. The approval is based on a randomized, multicenter, open-label phase II trial in patients with HER2positive operable, locally advanced, or inflammatory breast cancer (T24d).2,3 Breast tumor samples were required to show HER2 overexpression (immunohistochemistry [IHC] 3+

A total of 417 patients were randomly assigned to receive one of four neoadjuvant regimens: trastuzumab plus docetaxel (n = 107), pertuzumab plus trastuzumab and docetaxel (n = 107), pertuzumab plus trastuzumab (n = 107), or pertuzumab plus docetaxel (n = 96). Pertuzumab (initial dose of 840 mg, followed by 420 mg), trastu-

zumab (initial dose of 8 mg/kg, followed by 6 mg/kg), and docetaxel (75 mg/m2, escalated to 100 mg/m2 at investigator discretion) were administered preoperatively by intravenous infusion every 3 weeks for a total of four cycles. Following surgery, all patients received three cycles of fluorouracil, epirubicin, and cyclophosphamide (FEC) intravenously every 3 weeks, and trastuzumab was administered intravenously every 3 weeks to complete 1 year of therapy. The primary endpoint was pathologic complete response rate, defined as the absence of invasive cancer in

As a result, pertuzumab inhibits ligand-initiated intracellular signaling through two major pathways,

Pertuzumab for Early Breast Cancer ■■ Pertuzumab was granted accelerated approval for use in combination with

trastuzumab and docetaxel for neoadjuvant treatment of patients with HER2-positive locally advanced, inflammatory, or early-stage breast cancer.

■■ The recommended dose and schedule of pertuzumab is an initial dose

of 840 mg administered intravenously as a 60-minute infusion followed every 3 weeks by 420 mg administered intravenously as a 30- to 60-minute infusion.

the breast (ypT0/is). The FDA-preferred definition of pathologic complete response is the absence of invasive cancer in the breast and lymph nodes (ypT0/is ypN0). Demographics were well balanced among treatment groups. Median ages were 49 to 50 years, 71% of patients were Caucasian, 7% had inflammatory breast cancer, 32% had locally advanced cancer, 61% had operable cancer, 70% had clinically node-positive cancer, and 47% had hormone receptor (HR)-positive disease. Statistically significant improvements in pathologic complete response rates by both the study definition and the FDA-preferred definition (39.3% vs 21.5%, difference of 17.8%, adjusted P = .0063) were observed in patients receiving pertuzumab plus trastuzumab/docetaxel vs patients receiving trastuzumab/docetaxel. The pathologic complete response rates and magnitude of improvement with pertuzumab were lower in the subgroup of patients with HR-positive tumors (22.0% vs 12.0%) compared with patients with HR-negative tumors (54.4% vs 29.8%).

How It Works Pertuzumab is a recombinant hu-

mitogen-activated protein kinase, and phosphoinositide 3-kinase. Inhibition of these signaling pathways can result in cell growth arrest and apoptosis, respectively. In addition, pertuzumab mediates antibody-dependent cell-mediated cytotoxicity.

How It Is Given The recommended dose and schedule of pertuzumab is an initial dose of 840 mg administered intravenously as a 60-minute infusion followed every 3 weeks by 420 mg administered intravenously as a 30- to 60-minute infusion. Pertuzumab should be administered every 3 weeks for three to six cycles as part of one of the following treatment regimens for early breast cancer: four preoperative cycles of pertuzumab in combination with trastuzumab/docetaxel followed by three postoperative cycles of FEC; three preoperative cycles of FEC alone followed by three preoperative cycles of pertuzumab in combination with docetaxel/trastuzumab; or six preoperative cycles of pertuzumab in combination with docetaxel, carboplatin, and trastuzumab. Following surgery, patients should continue to receive trastuzumab to complete 1 year of treatment. There is

insufficient evidence to recommend continued use of pertuzumab for greater than six cycles for early breast cancer. There is insufficient evidence to recommend concomitant administration of an anthracycline with pertuzumab, and there are no safety data to support sequential use of doxorubicin with pertuzumab.

Safety Profile In the primary trial supporting approval, the most common adverse events (> 30%) with pertuzumab in combination with trastuzumab/ docetaxel were alopecia (65% vs 66% with trastuzumab/docetaxel), neutropenia (50.5% vs 64%), diarrhea (46% vs 34%), and nausea (39% vs 36%). The most common grade 3 or 4 adverse events (>2%) were neutropenia (45% vs 59%), febrile neutropenia (8.4% vs 6.5%), leukopenia (4.7% vs 11.2%), and diarrhea (5.6% vs 3.7%). Other significant adverse events reported with pertuzumab included left-ventricular dysfunction, infusion-related reactions, hypersensitivity reactions, and anaphylaxis. The approval is supported by an additional randomized phase II study conducted in 225 patients with HER2-positive locally advanced, operable, or inflammatory (T2-4d) breast cancer designed primarily to assess cardiac safety when FEC or carboplatin is incorporated into the preoperative regimen. Pertuzumab carries a boxed warning for cardiomyopathy and embryo-fetal toxicity. The cardiomyopathy warning is based on an increased rate of leftventricular ejection fraction decline observed in neoadjuvant trials. Cardiac function should be evaluated prior to and during treatment with pertuzumcontinued on page 66

Must commit either to abstain continuously from heterosexual sexual intercourse or to use 2 methods of reliable birth control, beginning 4 weeks prior to initiating treatment with POMALYST, during therapy, during dose interruptions and continuing for 4 weeks following discontinuation of POMALYST therapy. Must obtain 2 negative pregnancy tests prior to initiating therapy • Males: Pomalidomide is present in the semen of patients receiving the drug. Males must always use a latex or synthetic condom during any sexual contact with females of reproductive potential while taking POMALYST and for up to 28 days after discontinuing POMALYST, even if they have undergone a successful vasectomy. Males must not donate sperm • Blood Donation: Patients must not donate blood during treatment with POMALYST and for 1 month following discontinuation of the drug because the blood might be given to a pregnant female patient whose fetus must not be exposed to POMALYST

POMALYST REMS Program Because of the embryo-fetal risk, POMALYST is available only through a restricted program under a Risk Evaluation and Mitigation Strategy (REMS) called “POMALYST REMS.” Prescribers and pharmacists must be certified with the program; patients must sign an agreement form and comply with the requirements. Further information about the POMALYST REMS program is available at [celgeneriskmanagement.com] or by telephone at 1-888-423-5436.

Venous Thromboembolism: Patients receiving POMALYST have developed venous thromboembolic events reported as serious

adverse reactions. In the trial, all patients were required to receive prophylaxis or antithrombotic treatment. The rate of DVT or PE was 3%. Consider anticoagulation prophylaxis after an assessment of each patient’s underlying risk factors.

Hematologic Toxicity: Neutropenia of any grade was reported in 50% of patients and was the most frequently reported

Grade 3/4 adverse event, followed by anemia and thrombocytopenia. Monitor patients for hematologic toxicities, especially neutropenia, with complete blood counts weekly for the first 8 weeks and monthly thereafter. Treatment is continued or modified for Grade 3 or 4 hematologic toxicities based upon clinical and laboratory findings. Dosing interruptions and/or modifications are recommended to manage neutropenia and thrombocytopenia.

Hypersensitivity Reactions: Patients with a prior history of serious hypersensitivity associated with thalidomide or lenalidomide were excluded from studies and may be at higher risk of hypersensitivity.

Dizziness and Confusional State: 18% of patients experienced dizziness and 12% of patients experienced a confusional state;

1% of patients experienced grade 3/4 dizziness, and 3% of patients experienced grade 3/4 confusional state. Instruct patients to avoid situations where dizziness or confusion may be a problem and not to take other medications that may cause dizziness or confusion without adequate medical advice.


WARNINGS AND PRECAUTIONS (continued) Neuropathy: 18% of patients experienced neuropathy (approximately 9% peripheral neuropathy). There were no cases of grade 3 or higher neuropathy adverse reactions reported.

Risk of Second Primary Malignancies: Cases of acute myelogenous leukemia have been reported in patients receiving POMALYST as an investigational therapy outside of multiple myeloma.

ADVERSE REACTIONS In the clinical trial of 219 patients who received POMALYST alone (n=107) or POMALYST + low-dose dexamethasone (low-dose dex) (n=112), all patients had at least one treatment-emergent adverse reaction. • In the POMALYST alone versus POMALYST + low dose dexamethasone arms, respectively, most common adverse reactions (≥30%) included fatigue and asthenia (55%, 63%), neutropenia (52%, 47%), anemia (38%, 39%), constipation (36%, 35%), nausea (36%, 22%), diarrhea (34%, 33%), dyspnea (34%, 45%), upper respiratory tract infection (32%, 25%), back pain (32%, 30%), and pyrexia (19%, 30%) • 90% of patients treated with POMALYST alone and 88% of patients treated with POMALYST + low-dose dex had at least one treatment-emergent NCI CTC Grade 3 or 4 adverse reaction • In the POMALYST alone versus POMALYST + low dose dexamethasone arms, respectively, most common Grade 3/4 adverse reactions (≥15%) included neutropenia (47%, 38%), anemia (22%, 21%), thrombocytopenia (22%, 19%), and pneumonia (16%, 23%). For other Grade 3 or 4 toxicities besides neutropenia and thrombocytopenia, hold treatment and restart treatment at 1 mg less than the previous dose when toxicity has resolved to less than or equal to Grade 2 at the physician’s discretion • 67% of patients treated with POMALYST and 62% of patients treated with POMALYST + low-dose dex had at least one treatment-emergent serious adverse reaction • In the POMALYST alone versus POMALYST + low dose dexamethasone arms, respectively, most common serious adverse reactions (≥5%) were pneumonia (14%, 19%), renal failure (8%, 6%), dyspnea (5%, 6%), sepsis (6%, 3%), pyrexia (3%, 5%) dehydration (5%, 3%), hypercalcemia (5%, 2%), urinary tract infection (0%, 5%), and febrile neutropenia (5%, 1%)

DRUG INTERACTIONS No formal drug interaction studies have been conducted with POMALYST. Pomalidomide is primarily metabolized by CYP1A2 and CYP3A. Pomalidomide is also a substrate for P-glycoprotein (P-gp). Coadministration of POMALYST with drugs that are strong inhibitors or inducers of CYP1A2, CYP3A, or P-gp should be avoided. Cigarette smoking may reduce pomalidomide exposure due to CYP1A2 induction. Patients should be advised that smoking may reduce the efficacy of pomalidomide.

USE IN SPECIFIC POPULATIONS Pregnancy: If pregnancy does occur during treatment, immediately discontinue the drug and refer patient to an obstetrician/

gynecologist experienced in reproductive toxicity for further evaluation and counseling. Report any suspected fetal exposure to POMALYST to the FDA via the MedWatch program at 1-800-332-1088 and also to Celgene Corporation at 1-888-423-5436.

Nursing Mothers: It is not known if pomalidomide is excreted in human milk. Pomalidomide was excreted in the milk of lactating rats. Because many drugs are excreted in human milk and because of the potential for adverse reactions in nursing infants from POMALYST, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.

Pediatric Use: Safety and effectiveness of POMALYST in patients under the age of 18 have not been established. Geriatric Use: No dosage adjustment is required for POMALYST based on age. Patients greater than or equal to 65 years of age

were more likely than patients less than or equal to 65 years of age to experience pneumonia.

Renal and Hepatic Impairment: Pomalidomide is metabolized in the liver. Pomalidomide and its metabolites are primarily

excreted by the kidneys. The influence of renal and hepatic impairment on the safety, efficacy, and pharmacokinetics of pomalidomide has not been evaluated. Avoid POMALYST in patients with a serum creatinine >3.0 mg/dL. Avoid POMALYST in patients with serum bilirubin >2.0 mg/dL and AST/ALT >3.0 x ULN.

POMALYST is contraindicated in females who are pregnant. Pomalidomide is a thalidomide analogue, and is teratogenic in both rats and rabbits when administered during the period of organogenesis. If this drug is used during pregnancy or if the patient becomes pregnant while taking this drug, the patient should be apprised of the potential hazard to a fetus. 5 WARNINGS AND PRECAUTIONS 5.1 Embryo-Fetal Toxicity POMALYST is a thalidomide analogue and is contraindicated for use during pregnancy. Thalidomide is a known human teratogen that causes severe birth defects or embryo-fetal death [see Use in Specific Populations (8.1)]. POMALYST is only available through the POMALYST REMS program [see Warnings and Precautions (5.2)].Females of Reproductive Potential Females of reproductive potential must avoid pregnancy while taking POMALYST and for at least 4 weeks after completing therapy. Females must commit either to abstain continuously from heterosexual sexual intercourse or to use two methods of reliable birth control, beginning 4 weeks prior to initiating treatment with POMALYST, during therapy, during dose interruptions and continuing for 4 weeks following discontinuation of POMALYST therapy. Two negative pregnancy tests must be obtained prior to initiating therapy. The first test should be performed within 10-14 days and the second test within 24 hours prior to prescribing POMALYST therapy and then weekly during the first month, then monthly thereafter in women with regular menstrual cycles or every 2 weeks in women with irregular menstrual cycles [see Use in Specific Populations (8.6)].Males Pomalidomide is present in the semen of patients receiving the drug. Therefore, males must always use a latex or synthetic condom during any sexual contact with females of reproductive potential while taking POMALYST and for up to 28 days after discontinuing POMALYST, even if they have undergone a successful vasectomy. Male patients taking POMALYST must not donate sperm [see Use in Specific Populations (8.6)]. Blood Donation Patients must not donate blood during treatment with POMALYST and for 1 month following discontinuation of the drug because the blood might be given to a pregnant female patient whose fetus must not be exposed to POMALYST. 5.2 POMALYST REMS ™ Program Because of the embryo-fetal risk [see Warnings and Precautions

(5.1)], POMALYST is available only through a restricted program under a Risk Evaluation and Mitigation Strategy (REMS) called “POMALYST REMS.” Required components of the POMALYST REMS program include the following: • Prescribers must be certified with the POMALYST REMS program by enrolling and complying with the REMS requirements. • Patients must sign a Patient-Prescriber agreement form and comply with the REMS requirements. In particular, female patients of reproductive potential who are not pregnant must comply with the pregnancy testing and contraception requirements [see Use in Specific Populations (8.6)] and males must comply with contraception requirements [see Use in Specific Populations (8.6)]. • Pharmacies must be certified with the POMALYST REMS program, must only dispense to patients who are authorized to receive POMALYST and comply with REMS requirements. Further information about the POMALYST REMS program is available at [celgeneriskmanagement.com] or by telephone at 1-888-423-5436. 5.3 Venous Thromboembolism Patients receiving POMALYST have developed venous thromboembolic events (Venous Thromboembolism [VTEs]) reported as serious adverse reactions. In the trial, all patients were required to receive prophylaxis or anti-thrombotic treatment; 81% used aspirin, 16% warfarin, 21% heparin, and 3% clopidogrel. The rate of deep vein thrombosis or pulmonary embolism was 3%. Consider anti-coagulation prophylaxis after an assessment of each patient’s underlying risk factors. 5.4 Hematologic Toxicity Neutropenia was the most frequently reported Grade 3/4 adverse event (AE), followed by anemia and thrombocytopenia. Neutropenia of any grade was reported in 50% of patients in the trial. The rate of Grade 3/4 neutropenia was 43%. The rate of febrile neutropenia was 3%. Monitor patients for hematologic toxicities, especially neutropenia. Monitor complete blood counts weekly for the first 8 weeks and monthly thereafter. Patients may require dose interruption and/or modification [see Dosage and Administration (2.2)]. 5.5 Hypersensitivity Reactions. Patients with a prior history of serious hypersensitivity associated with thalidomide or lenalidomide were excluded from studies and may be at higher risk of hypersensitivity. 5.6 Dizziness and Confusional State. In the trial, 18% of patients experienced dizziness and 12% of patients experienced a confusional state; 1% of patients experienced grade 3/4 dizziness, and 3% of patients experienced grade 3/4 confusional state. Instruct patients to avoid situations where dizziness or confusion may be a problem and not to take other medications that may cause dizziness or confusion without adequate medical advice. 5.7 Neuropathy In the trial, 18% of patients experienced neuropathy, with approximately 9% of the patients experiencing peripheral neuropathy. There were no cases of grade 3 or higher neuropathy adverse reactions reported. 5.8 Risk of Second Primary Malignancies Cases of acute myelogenous leukemia have been reported in patients receiving POMALYST as an investigational therapy outside of multiple myeloma. 6 ADVERSE REACTIONS The following adverse reactions are described in detail in other labeling sections: • Fetal Risk [see Boxed Warnings, Warnings and Precautions (5.1, 5.2)] • Venous Thromboembolism [see Boxed Warnings, Warnings and Precautions (5.3)] • Hematologic Toxicity [see Warnings and Precautions (5.4)] • Hypersensitivity Reactions [see Warnings and Precautions (5.5)]

Interim Data Reported From Phase IB Study of Investigational Anti-PD-1 Immunotherapy for NSCLC

I

nterim data from a Phase IB trial evaluating the investigational antiPD-1 immunotherapy, MK-3475, in patients with previously treated nonsmall cell lung cancer (NSCLC) were • Dizziness and Confusional State [see Warnings and Precautions (5.6)] • Neuropathy [see Warnings and Precautions (5.7)] • Risk of Second Primary Malignancies [see Warnings and Precautions (5.8)] 6.1 Clinical Trials Experience in Multiple Myeloma Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. In clinical trial 1, data were evaluated from 219 patients (safety population) who received treatment with POMALYST + Low Dose Dexamethasone (Low dose Dex) (112 patients) or POMALYST alone (107 patients). Median number of treatment cycles was 5. Sixty three percent of patients in the study had a dose interruption of either drug due to adverse reactions. Thirty seven percent of patients in the study had a dose reduction of either drug due to adverse reactions. The discontinuation rate due to treatment-related adverse reaction was 3%. Tables 2, 3 and 4 summarize all treatment-emergent adverse reactions reported for POMALYST + Low dose Dex and POMALYST alone groups regardless of attribution of relatedness to pomalidomide. In the absence of a randomized comparator arm, it is often not possible to distinguish adverse events that are drug-related and those that reflect the patient’s underlying disease. In the clinical trial of 219 patients who received POMALYST alonea (n=107) or POMALYST + Lowdose Dex (n=112), all patients had at least one treatment-emergent adverse reaction. Adverse reactions ≥10% in either arm, respectively, included: General disorders and administration site conditions: Fatigue and asthenia (55%, 63%), Pyrexia (19%, 30%), Edema peripheral (23%, 16%), Chills (9%, 11%), Pain (6%, 5%); Blood and lymphatic system disorders: Neutropenia (52%, 47%), Anemia (38%, 39%), Thrombocytopenia (25%, 23%), Leukopenia (11%, 18%), Lymphopenia (4%, 15%); Gastrointestinal disorders: Constipation (36%, 35%), Diarrhea (34%, 33%), Nausea (36%, 22%), Vomiting (14%, 13%); Infections and infestations: Pneumonia (23%, 29%), Upper respiratory tract infection (32%, 25%), Urinary tract infection (8%, 16%); Musculoskeletal and connective tissue disorders: Back pain (32%, 30%), Musculoskeletal chest pain (22%, 20%), Muscle spasms (19%, 19%), Arthralgia (16%, 15%), Musculoskeletal pain (11%, 15%), Pain in extremity (5%, 14%), Muscular weakness (12%, 12%), Bone pain (12%, 5%); Respiratory, thoracic and mediastinal disorders: Dyspnea (34%, 45%), Cough (14%, 21%), Epistaxis (15%, 11%); Metabolism and nutritional disorders: Decreased appetite (22%, 18%), Hyperglycemia (12%, 15%), Hyponatremia (10%, 13%), Hypercalcemia (21%, 12%), Hypocalcemia (6%, 12%), Hypokalemia (10%, 11%); Skin and subcutaneous tissue disorders: Hyperhidrosis (6%, 16%), Rash (22%, 16%), Night sweats (5%, 13%), Dry skin (9%, 11%), Pruritus (15%, 11%); Nervous system disorders: Dizziness (20%, 17%), Tremor (9%, 13%), Headache (13%, 8%), Neuropathy peripheral (10%, 7%); Investigations: Blood creatinine increased (15%, 11%), Weight increased (1%, 11%), Weight decreased (14%, 8%); Psychiatric disorders: Insomnia (7%, 14%), Confusional state (10%, 13%), Anxiety (11%, 7%); Renal and urinary disorders: Renal failure (15%, 10%). Grade 3/4 adverse reactions reported in 90% of patients treated with POMALYSTa alone (96/107) and 88% with POMALYST + Low dose Dex (99/112).

Other Adverse Reactions Other adverse reactions of POMALYST in patients with multiple myeloma, not described above, and considered important: Ear and Labyrinth Disorders: Vertigo; Hepatobiliary Disorders: Hyperbilirubinemia; Infections and Infestations: Pneumocystis jiroveci pneumonia, Respiratory syncytial virus infection, Neutropenic sepsis; Investigations: Alanine aminotransferase increased; Metabolism and Nutritional Disorders: Hyperkalemia; Renal and Urinary Disorders: Urinary retention; Reproductive System and Breast Disorders: Pelvic Pain; Respiratory, Thoracic and Mediastinal Disorders: Interstitial Lung Disease 7 DRUG INTERACTIONS No formal drug interaction studies have been conducted with POMALYST. Pomalidomide is primarily metabolized by CYP1A2 and CYP3A. Pomalidomide is also a substrate for P-glycoprotein (P-gp). 7.1 Drugs That May Increase Pomalidomide Plasma Concentrations CYP3A, CYP1A2 or P-gp inhibitors: Co-administration of POMALYST with drugs that are strong inhibitors of CYP1A2, CYP3A (e.g. ketoconazole) or P-gp could increase exposure and should be avoided. 7.2 Drugs That May Decrease Pomalidomide Plasma Concentrations CYP3A, CYP1A2 or P-gp inducers: Co-administration of POMALYST with drugs that are strong inducers of CYP1A2, CYP3A (e.g. rifampin) or P-gp could decrease exposure and should be avoided. Smoking: Cigarette smoking may reduce pomalidomide exposure due to CYP1A2 induction. Patients should be advised that smoking may reduce the efficacy of pomalidomide. Dexamethasone: Co-administration of multiple doses of 4 mg POMALYST with 20 mg to 40 mg dexamethasone (a weak inducer of CYP3A) to patients with multiple myeloma had no effect on the pharmacokinetics of pomalidomide compared with pomalidomide administered alone. 8 USE IN SPECIFIC POPULATIONS 8.1 Pregnancy Pregnancy Category X [see Boxed Warnings and Contraindications (4)]

UCLA presented the findings. MK-3475 is an investigational, highly selective anti–PD-1 immunotherapy designed to restore the natural ability of the immune system to Risk Summary POMALYST can cause embryo-fetal harm when administered to a pregnant female and is contraindicated during pregnancy. POMALYST is a thalidomide analogue. Thalidomide is a human teratogen, inducing a high frequency of severe and life-threatening birth defects such as amelia (absence of limbs), phocomelia (short limbs), hypoplasticity of the bones, absence of bones, external ear abnormalities (including anotia, micropinna, small or absent external auditory canals), facial palsy, eye abnormalities (anophthalmos, microphthalmos), and congenital heart defects. Alimentary tract, urinary tract, and genital malformations have also been documented and mortality at or shortly after birth has been reported in about 40% of infants. Pomalidomide was teratogenic in both rats and rabbits when administered during the period of organogenesis. If this drug is used during pregnancy or if the patient becomes pregnant while taking this drug, the patient should be apprised of the potential hazard to a fetus. If pregnancy does occur during treatment, immediately discontinue the drug. Under these conditions, refer patient to an obstetrician/gynecologist experienced in reproductive toxicity for further evaluation and counseling. Report any suspected fetal exposure to POMALYST to the FDA via the MedWatch program at 1-800-332-1088 and also to Celgene Corporation at 1-888-423-5436. Animal Data Pomalidomide was teratogenic in both rats and rabbits in the embryofetal developmental studies, when administered during the period of organogenesis. In rats, pomalidomide was administered orally to pregnant animals at doses of 25 to 1000 mg per kg per day. Malformations of absence of urinary bladder, absence of thyroid gland, and fusion and misalignment of lumbar and thoracic vertebral elements (vertebral, central and/or neural arches) were observed at all dose levels. There was no maternal toxicity observed in this study. The lowest dose in rats resulted in an exposure (AUC) approximately 85-fold of the human exposure at the recommended dose of 4 mg per day. Other embryofetal toxicities included increased resorptions leading to decreased number of viable fetuses. In rabbits, pomalidomide was administered orally to pregnant animals at doses of 10 to 250 mg per kg per day. Increased cardiac malformations such as interventricular septal defect were seen at all doses with significant increases at 250 mg per kg per day. Additional malformations observed at 250 mg per kg per day included anomalies in limbs (flexed and/or rotated fore- and/or hindlimbs, unattached or absent digit) and associated skeletal malformations (not ossified metacarpal, misaligned phalanx and metacarpal, absent digit, not ossified phalanx, and short not ossified or bent tibia), moderate dilation of the lateral ventricle in the brain, abnormal placement of the right subclavian artery, absent intermediate lobe in the lungs, low-set kidney, altered liver morphology, incompletely or not ossified pelvis, an increased average for supernumerary thoracic ribs and a reduced average for ossified tarsals. No maternal toxicity was observed at the low dose (10 mg per kg per day) that resulted in cardiac anomalies in fetuses; this dose resulted in an exposure (AUC) approximately equal to that reported in humans at the recommended dose of 4 mg per day. Additional embryofetal toxicity included increased resorption. 8.3 Nursing mothers It is not known if pomalidomide is excreted in human milk. Pomalidomide was excreted in the milk of lactating rats. Because many drugs are excreted in human milk and because of the potential for adverse reactions in nursing infants from POMALYST, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother. 8.4 Pediatric use Safety and effectiveness of POMALYST in patients below the age of 18 have not been established.

15th World Conference on Lung Cancer Anti-PD-1 Immunotherapy

In the phase IB trial, a cohort of 38 patients with previously treated

NSCLC were given MK-3475 10 mg/ kg every 3 weeks. The objective response rate in patients with squamous and nonsquamous subtypes receiving MK-3475 was 24% by investigatorassessed, immune-related assessed criteria (irRC) and 21% per RECIST 1.1 criteria. The median overall survival at the time of analysis was 51 weeks with

8.5 Geriatric use No dosage adjustment is required for POMALYST based on age. Of the total number of patients in clinical studies of POMALYST, 41 percent were 65 and over, while 12 percent were 75 and over. No overall differences in effectiveness were observed between these patients and younger patients. In this study, patients greater than or equal to 65 years of age were more likely than patients less than or equal to 65 years of age to experience pneumonia. 8.6 Females of Reproductive Potential and Males POMALYST can cause fetal harm when administered during pregnancy [see Use in Specific Populations (8.1)]. Females of reproductive potential must avoid pregnancy while taking POMALYST and for at least 4 weeks after completing therapy. Females Females of reproductive potential must commit either to abstain continuously from heterosexual sexual intercourse or to use two methods of reliable birth control simultaneously (one highly effective form of contraception – tubal ligation, IUD, hormonal (birth control pills, injections, hormonal patches, vaginal rings or implants) or partner’s vasectomy and one additional effective contraceptive method – male latex or synthetic condom, diaphragm or cervical cap. Contraception must begin 4 weeks prior to initiating treatment with POMALYST, during therapy, during dose interruptions and continuing for 4 weeks following discontinuation of POMALYST therapy. Reliable contraception is indicated even where there has been a history of infertility, unless due to hysterectomy. Females of reproductive potential should be referred to a qualified provider of contraceptive methods, if needed. Females of reproductive potential must have 2 negative pregnancy tests before initiating POMALYST. The first test should be performed within 10-14 days, and the second test within 24 hours prior to prescribing POMALYST. Once treatment has started and during dose interruptions, pregnancy testing for females of reproductive potential should occur weekly during the first 4 weeks of use, then pregnancy testing should be repeated every 4 weeks in females with regular menstrual cycles. If menstrual cycles are irregular, the pregnancy testing should occur every 2 weeks. Pregnancy testing and counseling should be performed if a patient misses her period or if there is any abnormality in her menstrual bleeding. POMALYST treatment must be discontinued during this evaluation. Males Pomalidomide is present in the semen of males who take POMALYST. Therefore, males must always use a latex or synthetic condom during any sexual contact with females of reproductive potential while taking POMALYST and for up to 28 days after discontinuing POMALYST, even if they have undergone a successful vasectomy. Male patients taking POMALYST must not donate sperm. 8.7 Renal Impairment Pomalidomide and its metabolites are primarily excreted by the kidneys [see Clinical Pharmacology (12.3)]. The influence of renal impairment on the safety, efficacy, and pharmacokinetics of pomalidomide has not been evaluated. Patients with serum creatinine greater than 3.0 mg/dL were excluded in clinical studies. Avoid POMALYST in patients with a serum creatinine greater than 3.0 mg/dL. 8.8 Hepatic Impairment Pomalidomide is metabolized in the liver [see Clinical Pharmacology (12.3)]. The influence of hepatic impairment on the safety, efficacy, and pharmacokinetics of pomalidomide has not been evaluated. Patients with serum bilirubin greater than 2.0 mg/dL and AST/ALT greater than 3.0 x upper limit normal (ULN) were excluded in clinical studies. Avoid POMALYST in patients with serum bilirubin greater than 2.0 mg/dL and AST/ALT greater than 3.0 x ULN. 10 OVERDOSAGE No specific information is available on the treatment of overdose with pomalidomide, and it is unknown whether pomalidomide or its metabolites are dialyzable.

13 NONCLINICAL TOXICOLOGY 13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility Studies examining the carcinogenic potential of pomalidomide have not been conducted. One of twelve monkeys dosed with 1 mg/kg of pomalidomide (an exposure approximately 15-fold of the exposure in patients at the recommended dose of 4 mg/per day) developed acute myeloid leukemia in a 9-month repeat-dose toxicology study. Pomalidomide was not mutagenic or clastogenic in a battery of tests, including the bacteria reverse mutation assay (Ames test), the in vitro assay using human peripheral blood lymphocytes and the micronucleus test in orally treated rats administered doses up to 2000 mg/kg/day. In a fertility and early embryonic development study in rats, drug-treated males were mated with untreated or treated females. Pomalidomide was administered to males and females at doses of 25 to 1000 mg/kg/day. When treated males were mated with treated females, there was an increase in post-implantation loss and a decrease in mean number of viable embryos at all dose levels. There were no other effects on reproductive functions or the number of pregnancies. The lowest dose tested in animals resulted in an exposure (AUC) approximately 100-fold of the exposure in patients at the recommended dose of 4 mg/day. When treated males on this study were mated with untreated females, all uterine parameters were comparable to the controls. Based on these results, the observed effects were attributed to the treatment of females. 17 PATIENT COUNSELING INFORMATION See FDA- approved Patient labeling (Medication Guide). Embryo-Fetal Toxicity Advise patients that POMALYST is contraindicated in pregnancy [see Contraindicatons (4)]. POMALYST is a thalidomide analog and may cause serious birth defects or death to a developing baby. [see Warnings and Precautions (5.1) and Use in Specific Populations (8.1)]. • Advise females of reproductive potential that they must avoid pregnancy while taking POMALYST and for at least 4 weeks after completing therapy. • Initiate POMALYST treatment in females of reproductive potential only following a negative pregnancy test. • Advise females of reproductive potential of the importance of monthly pregnancy tests and the need to use two different forms of contraception including at least one highly effective form simultaneously during POMALYST therapy, during therapy interruption and for 4 weeks after she has completely finished taking POMALYST. Highly effective forms of contraception other than tubal ligation include IUD and hormonal (birth control pills, injections, patch or implants) and a partner’s vasectomy. Additional effective contraceptive methods include latex or synthetic condom, diaphragm and cervical cap. • Instruct patient to immediately stop taking POMALYST and contact her doctor if she becomes pregnant while taking this drug, if she misses her menstrual period, or experiences unusual menstrual bleeding, if she stops taking birth control, or if she thinks FOR ANY REASON that she may be pregnant. • Advise patient that if her doctor is not available, she can call 1-888-668-2528 for information on emergency contraception [see Warnings and Precautions (5.1) and Use in Specific Populations (8.6)]. • Advise males to always use a latex or synthetic condom during any sexual contact with females of reproductive potential while taking POMALYST and for up to 28 days after discontinuing POMALYST, even if they have undergone a successful vasectomy. • Advise male patients taking POMALYST that they must not donate sperm [see Warnings and

Precautions (5.1) and Use in Specific Populations (8.6)]. • All patients must be instructed to not donate blood while taking POMALYST and for 1 month following discontinuation of POMALYST [see Warnings and Precautions (5.1) and Use in Specific Populations (8.6)]. POMALYST REMS Program Because of the risk of embryo-fetal toxicity, POMALYST is only available through a restricted program call POMALYST REMS [see Warnings and Precautions (5.2)]. • Patients must sign a Patient-Prescriber agreement form and comply with the requirements to receive POMALYST. In particular, females of reproductive potential must comply with the pregnancy testing, contraception requirements and participate in monthly telephone surveys. Males must comply with the contraception requirements [see Use in Specific Populations (8.6)]. • POMALYST is available only from pharmacies that are certified in POMALYST REMS program. Provide patients with the telephone number and website for information on how to obtain the product. Venous Thromboembolism Inform patients of the potential risk of developing venous thromboembolic events and discuss the need for appropriate prophylactic treatment. Hematologic Toxicities Inform patients on the risks of developing neutropenia, thrombocytopenia and anemia and the need to report signs and symptoms associated with these events to their health care provider for further evaluation. Hypersensitivity Inform patients of the potential for a severe hypersensitivity reaction to POMALYST if they have had such a reaction in the past to either THALOMID® or REVLIMID®. Dizziness and Confusional State Inform patients of the potential risk of dizziness and confusion with the drug and to avoid situations where dizziness or confusion may be a problem and not to take other medications that may cause dizziness or confusion without adequate medical advice. Neuropathy Inform patients of the risk of neuropathy and report the signs and symptoms associated with these events to their health care provider for further evaluation. Second Primary Malignancies Inform the patient that the potential risk of developing acute myelogenous leukemia during treatment with POMALYST is unknown. Dosing Instructions Inform patients on how to take POMALYST [see Dosage and Administration (2.1)] • POMALYST should be taken once daily at about the same time each day • POMALYST should be taken without food (at least 2 hours before or 2 hours after a meal). • The capsules should not be opened, broken, or chewed. POMALYST should be swallowed whole with water. • Instruct patients that if they miss a dose of POMALYST, they may still take it up to 12 hours after the time they would normally take it. If more than 12 hours have elapsed, they should be instructed to skip the dose for that day. The next day, they should take POMALYST at the usual time. Warn patients not to take 2 doses to make up for the one that they missed. Other Information Advise patients who smoke to stop because smoking may reduce the efficacy of pomalidomide [see Drug Interactions (7.2)].

adverse events were low grade (grade 1–2), and there was one incident of grade 3 pulmonary edema.

Effect of PD-L1 Expression Status An analysis of the relationship between PD-L1 expression status and response rates in this NSCLC patient cohort was also presented. Tumor

Edward Garon, MD

samples were analyzed and classified as expressing either zero/low or high levels of PD-L1. High levels of expression according to the assay criteria were associated with response rates of 67% (95% confidence interval [CI] = 30–93) per irRC and 57% (95% CI = 18–90) per RECIST 1.1 criteria. In comparison, tumor samples expressing zero/low levels of PD-L1, according to assay criteria, were associated with response rates of 4% (95% CI = 0–21) per irRC and 9% per RECIST (95% CI = 1–29). More data are needed to better understand the relationship between PD-L1 expression and response to MK-3475. Based on these preliminary data, a phase II/III trial comparing two doses of MK-3475 vs docetaxel in patients with previously treated NSCLC who have received at least one prior treatment regimen has been initiated. n

ASCO Reconfirms Commitment to Choosing Wisely® Campaign Task Force on Value of Cancer Care Releases New ‘Top Five’ List

I

n collaboration with the American Board of Internal Medicine (ABIM) Foundation’s Choosing Wisely® campaign, ASCO recently released a second “Top Five” opportunities list of

common practices or procedures in oncology whose clinical value is not supported by available evidence and if eliminated, can improve the quality and value of patient care.

Value of Cancer Care Task Force Like the original “Top Five” list, published in 2012, the new list was developed under the leadership of ASCO’s Value of Cancer Care Task Force, a multidisciplinary group of oncologists that was formed to address the rising cost of cancer care in this country while tackling solutions to improve quality and value. “Even in an area of care like oncology, where you are dealing with a scary illness with uncertain outcomes, doing everything possible for a patient

is not always helpful,” said Lowell E. Schnipper, MD, Chair of the Value of Cancer Care Task Force. “There are plenty of things that we automatically do that may not add value to the patient.” According to Dr. Schnipper, ASCO members widely supported ASCO’s initial “Top Five” opportunities list, which called for the elimination of unnecessary chemotherapy for patients with advanced disease who were unlikely to benefit, the use of costly imaging technologies for detecting breast cancer recurrence and for the staging of early breast and prostate cancers that are unlikely to metastasize, and the use of drugs to prevent febrile neutropenia for patients at low risk for the complication. When the ABIM Foundation recently asked ASCO to participate in a second “Top Five” list, the Task Force began the work of soliciting ideas from ASCO committee members, which include clinical oncologists in the community and in academia with a wide variety of expertise. “ASCO has devoted considerable energy in focusing on value in cancer care, and identifying and rationalizing key areas where medical activity is not producing value,” said Derek Raghavan, MD, PhD, a member of ASCO’s Value of Cancer Care Task Force. “This campaign has focused on common cancers where common patterns of practice— either diagnostic tests or patterns of treatment—no lon-

ASCO Resources for Transitioning to ICD-10

A

SCO has developed resources to educate and assist oncology practices in transitioning to the Center for Medicare and Medicaid Services (CMS) 10th Edition of its International Classification of Diseases (ICD-10) coding system. Practices are encouraged to prepare for the transition before the October 1, 2014, deadline. On that date, ICD-10 will fully replace ICD-9 and providers may no longer bill with ICD-9 codes. Therefore, it is important to take the time to educate oneself about ICD-10 and determine what impact it will have on your practice. ASCO resources are available on its online resource center

for transitioning to ICD-10, which is available at http://www.asco.org /practice-research/icd-10. In addition, CMS has developed an online ICD-10 implementation guide that provides step-by-step guidance on how to transition to ICD-10. To access the webpage, please visit http://www .cms.gov/Medicare/Coding /ICD10/index .html ?redirect= /icd10.

“F

or oncologists, continuous quality improvement is a key goal. We measure and assess the quality of care we deliver and constantly look for areas where we can do better,” said ASCO President Clifford A. Hudis, MD, FACP. “ASCO’s Quality Training Program will guide oncology care providers in establishing methods and solutions to implement these quality improvements within their practices.” ASCO issued its first clinical practice guideline in 1994 and launched the Quality Oncology Practice Initiative (QOPI®), the first national program to help practices improve the quality of care they deliver, in 2006. The Quality Training Program represents an expanded opportunity for oncologists to improve care in their practice.

About the Program The 6-month Quality Training Program will offer 5 days of face-to-face education sessions between October 2013 and March 2014 at ASCO’s headquarters. Throughout the program, each practice will undertake its own focused quality improvement project, and the practice team will immediately be able to implement what they have

Breast Cancer Index Assay Prognostic for Distant Recurrence in Estrogen Receptor–Positive, Node-Negative Breast Cancer By Matthew Stenger

I

n a study reported in The Lancet Oncology, Dennis C. Sgroi, MD, of Massachusetts General Hospital, and colleagues compared the ability of the breast-cancer index (BCI) assay, 21-gene recurrence score (Oncotype DX), and an immunohistochemical prognostic model (IHC4) to predict early and late distant recurrence in patients with estrogen receptor (ER)-positive, node-negative breast cancer. The study showed that a BCI-linear model was superior to a BCI-cubic model. Further, while all tests were significantly prognostic for overall risk of recurrence and early recurrence, only the BCI-linear assay, which is comprised of two independently developed gene expression biomarkers, was significantly prognostic for late recurrence.

BCI-Linear vs BCI-Cubic The primary analysis showed significant differences in risk of distant recurrence over 10 years in the categorical BCI-cubic risk groups (P < .0001), with 6.8% of patients in the low-risk group, 17.3% in the intermediate-risk group, and 22.2% in the high-risk group having distant recurrence. Multivariate analysis showed that the BCI-linear test was a stronger predictor for overall distant recurrence compared with the BCI-cubic test (interquartile hazard ratio [HR] =

[The BCI-linear assay] was the only significant prognostic test for risk of both early and late distant recurrence and … could help to identify patients at high risk for late distant recurrence who might benefit from extended endocrine or other therapy.

Study Details The study was performed in 665 patients with ER-positive, nodenegative disease who received either tamoxifen or anastrozole monotherapy in the Arimidex, Tamoxifen, Alone or in Combination (ATAC) trial, using archived tumor blocks from patients for whom the 21-gene recurrence score and IHC4 values had already been ascertained. BCI analysis was performed in matched samples with sufficient residual RNA using BCI-linear and BCI-cubic models. The prognostic ability of the BCI assay for distant recurrence over 10 years (the primary endpoint) was determined and compared with that of the 21-gene recurrence score and IHC4 for overall 10-year, early (0–5 years), and late (5–10 years) distant recurrence. To assess the ability of the biomarkers to predict recurrence beyond standard clinicopathologic variables, the change in the likelihood-ratio χ2 (LR-Δχ2) was calculated from Cox proportional hazards models.

Δχ2 = 29.14, P < .0001) all were significantly prognostic for early distant recurrence. Similarly, the BCI-linear (HR = 2.77, 95% CI = 1.63–4.70, LR-Δχ2 = 15.42, P < .0001), 21-gene recurrence score (HR = 1.80, 95% CI = 1.42–2.29, LR-Δχ2 = 18.48, P < .0001), and the IHC4 (HR = 2.90, 95% CI = 2.01–4.18, LR-Δχ2 = 29.14, P < .0001) were all prognostic for early distant recurrence. However, only BCI-linear was prognostic for late distant recurrence (HR = 1.95, 95% CI = 1.22–3.14, LR-Δχ2 = 7.97, P = .0048), with the 21-gene recur-

2.30 (95% confidence interval [CI] = 1.62–3.27), LR-Δχ2 = 22.69, P < .0001) and that both the 21-gene recurrence score (HR = 1.48, 95% CI = 1.22–1.78], LR-Δχ2 = 13.68, P = .0002) and IHC4 (HR = 1.69, 95% CI = 1.51–2.56], LR-Δχ2 = 22.83, P < .0001) were less predictive than the BCI-linear test. All further analyses were done using the BCI-linear model.

Prognostic for Overall, Early, and Late Recurrence In multivariate analyses, the BCI-linear assay (HR = 2.77, 95% CI = 1.63–4.70, LR-Δχ2 = 15.42, P < .0001), 21-gene recurrence score (HR = 1.80, 95% CI = 1.42–2.29, LRΔχ2 = 18.48, P < .0001), and IHC4 (HR = 2.90, 95% CI = 2.01–4.18, LR-

rence score (HR = 1.13, 95% CI = 0.82–1.56, LR-Δχ2 = 0.48, P = .47) and the IHC4 (HR = 1.30, 95% CI = 0.88–1.94, LR-Δχ2 = 1.59, P = .20) not achieving significance. Results were similar in the subgroup of 597 HER2-negative patients, with all three tests being significantly prognostic for overall distant recurrence and early recurrence, but only BCI-linear being prognostic for late distant recurrence.

Two Distinct Risk Groups for Early and Late Recurrence A post hoc analysis of BCI-linear in early recurrence showed that there was little difference in distant recurrence at 5 years between the BCI lowrisk and intermediate-risk groups, which together included 556 (84%) of 665 patients with a combined 5-year rate of distant recurrence of 2.6%. The BCI high-risk group, which included 109 patients (16%), had a 5-year distant recurrence rate of 18·1%. After adjustment for clinical treatment score, the hazard ratio for the highrisk group vs this low-risk grouping was 4.61 (95% CI = 2.20–9.66). An analysis of late recurrence

showed that intermediate-risk and high-risk patients had highly similar rates of recurrence, with the combined groups including 230 (39%) of 596 patients with a distant recurrence rate of 13.4% for years 5 to 10. The low-risk group included 366 patients (61%) with a recurrence rate of 3.5% for years 5 to 10. After adjustment for clinical treatment score, the hazard ratio for this high-risk grouping vs the low-risk group was 2.94 (95% CI = 1.44–6.01). The investigators noted that these modified risk groupings could allow baseline identification of a relatively small group of patients at higher risk of early recurrence who might be considered for therapy in addition to endocrine therapy and a larger group that might be regarded as adequately treated with endocrine therapy. Similarly, the finding of two distinct risk groupings for late recurrence in patients remaining disease-free on adjuvant tamoxifen or aromatase inhibitor treatment at 5 years suggests that there is a sizable group of patients at low risk who may require no further systemic therapy. The investigators concluded, “[The BCI-linear assay] was the only significant prognostic test for risk of both early and late distant recurrence and identified two risk populations for each timeframe. It could help to identify patients at high risk for late distant recurrence who might benefit from extended endocrine or other therapy.” n Disclosure: The study was funded by the Avon Foundation, National Institutes of Health, Breast Cancer Foundation, U.S. Department of Defense Breast Cancer Research Program, Susan G.

or clinicians and health service researchers striving to improve care for people living with life-threatening conditions, September was a sobering month. The Dartmouth Atlas group released a brief report on Trends in Cancer Care Near the End of Life1 showing that while the proportion of patients with cancer who die in hospitals slightly decreased between 2003–2007 and 2010, patients in 2010 were more Dr. Byock is a palliative care physician and a Professor of Medicine at the Geisel School of Medicine at Dartmouth.

likely to receive life-sustaining treatments, spend time in an ICU in the final month of life, or undergo chemotherapy during the last 2 weeks of life (see related news item below). Moreover, while hospice use is up, many cancer patients are receiving hospice care only at the brink of death, for the last 3 to 7 days of life. Two weeks later, the Institute of Medicine published a 360-page report on Delivering High Quality Cancer Care, which was subtitled, Charting a New Course for a System in Crisis.2 This report details ongoing patterns of excessive disease treatments coupled with insufficient attention to cancer patients’ and their families’ comfort,

social support, and well-being.

Buyer Beware Cancer care statistics and data tables are deliberately anonymous, yet the people whose stories the facts and figures represent all had names and faces, feelings and families. Anyone who has cancer—or loves someone who has it—knows that cancer is profoundly personal. From the moment the test results come back and a doctor utters the words, “I’m afraid you have cancer,” people’s worlds are shaken. Getting the best care becomes Job 1. These days, that entails finding the best doctors and cancer centers in the area, searching the Internet for treat-

ment options, and seeking second (and sometimes third and fourth) opinions. Without notice and, in most cases, without preparation, the diagnosis turns patients and their families into “consumers” of health care. (I dislike the term, but it seems apt for the choices people with cancer must make.) Becoming an effective, discriminating consumer is essential because, as the graphs and data tables show, habits of medical practice vary dramatically from one region of the country to another—and even from one medical center to another within large cities. These regional and institutional practice patterns bias the types of care people receive, without their

lthough fewer Medicare patients with cancer died in the hospital in 2010 than in the years 2003–2007, aggressive treatment continues at the end of life, according to a new report from the Dartmouth Atlas Project.1 The findings also show that a significant number of patients were likely to receive lifesustaining treatments, including intubation, a feeding tube, or cardiopulmonary resuscitation, in the final month of life, or to undergo chemotherapy during the last 2 weeks of life.

Longitudinal Analysis The report examined trends in end-of-life care for advanced cancer patients across regions, academic medical centers, and National Cancer Institute–designated cancer centers. It is the first Dartmouth Atlas report with a longitudinal analysis of the care provided to Medicare patients with advanced cancer. According to the report, although

the percentage of patients with cancer receiving hospice care during the last month of life has increased to 61.3% in 2010 from 54.6% in 2003–2007, the percentage of patients admitted to hospice care during the last 3 days of life— when it is often too late to provide much benefit—rose from 8.3% in 2003–2007 to 10.9% in 2010. The report also found that most patients with cancer who are approaching the end of their lives prefer supportive care that minimizes symptoms and the number of days spent in the hospital. “Unfortunately, the care patients receive does not always reflect their own preferences, but the prevailing styles of treatment in the regions and health-care systems where they happen to receive cancer treatment,” wrote the authors.

diatrics and Health Policy at The Dartmouth Institute for Health Policy & Clinical Practice and coprincipal investigator of the Dartmouth Atlas Project, said, “Our research continues to find that patients with advanced cancer are often receiving aggressive care until their final days, when we know that most patients would prefer care directed toward a better quality of life through hospice and palliative services. The increase in patients admitted to hospice care only days before death suggests that hospice services are often provided too late to provide much benefit. Fuller discussions with patients who have advanced cancer on their prognosis and options for care can lead to a better quality of life than many receive today.”

Communication on Care Goals ASCO has been proactive in calling for an increase in physician-patient communication on treatment options and care goals immediately following a

diagnosis of advanced cancer and published a provisional clinical opinion on palliative care in 2012.2 “ASCO has long advocated for improved physician-patient communication about care preferences, especially for patients with advanced cancer,” said ASCO President Clifford A. Hudis, MD, FACP. “Over the past few years, we’ve seen data that show that patients who talk about these issues with their clinicians early in the course of treatment are more likely to receive the type of care they prefer. These important discussions lead to greater use of palliative and hospice care, and can improve a patient’s quality of life, sense of control, and satisfaction with their care and choices.”n

Disclosure: Drs. Goodman and Hudis reported no potential conflicts of interest.

Perspective

knowledge, and often in ways they would not want. Note to health-care consumers: Let the buyer beware. As a doctor who has helped care for people with advanced cancer for over 30 years, when my own relatives or personal friends are wrestling with treatment decisions and turn to me for advice, here is the perspective I offer. First, if you have a curable or highly treatable cancer, go for it! Get the best treatments you can and, within reason, stick with the program through predictably difficult times. Advances in oncology have made many of today’s treatments well worth the effort.

More Is Not Always Better However, if and when your cancer advances despite treatments and you find your strength, energy, appetite, and overall stamina are waning, be cautious about excessive medical care. The longstanding assumption is that the more diagnostic tests and treatments patients receive, the better off they will be. However, 2 decades of studies by Dartmouth Atlas researchers have proven that this supposition is often wrong.3 In advanced illnesses, including cancer, higher levels of medical treatments are commonly associated with more suffering but little or no extension of life. Yet when a person—someone’s mother or father, spouse, sibling, or child—is getting sicker, the desire to do something is strong. Under the influence of the more-is-better mentality, well-intentioned clinicians and loving families can inadvertently cause people to spend precious, fleeting days at the end of a long illness in hospitals and ICUs, instead of at home or other places they would rather be.

Palliative Care, Hospice Can Extend Life Don’t confuse palliative and hospice care with giving up hope of living longer. In actuality, patients with invasive cancers who receive palliative care along with cancer treatments tend to enjoy better quality of life and live longer.4,5 Similarly, cancer patients who receive hospice care tend to live longer than those who don’t.6 The reasons are not mysterious. Palliative care and hospice teams provide meticulous clinical attention to people’s pain and other symptoms, basic bodily needs (such as eating, sleeping, eliminating, washing, grooming, and getting around), as well as support for their emotional and spiritual concerns.

It’s little wonder that people with advanced cancer who receive such comprehensive whole-person care are able to feel a bit better and survive longer.

Since Cancer Is Personal, So Is Cancer Care The best care helps people live as comfortably and fully as possible through the very end of life. It supports people in the difficult but normal tasks of completing their affairs and relationships—includ-

Yet many people avoid talking about dying, as if talking about it will make death more likely. In reality, everyone knows cancer can be life-threatening. That’s why getting the best care is so important. If we don’t talk with our families and doctors about what we would want or not want, how are they to know? Published surveys can tell us what most people want as they come to the end of life, but one size does not fit all.

ing, if they wish, taking stock of their lives, telling their stories, and leaving a legacy to those they leave behind. The Institute of Medicine, American Cancer Society, and American Society of Clinical Oncology have all called for cancer care to be patientcentered and attend to the well-being of people living with cancer.7-10 Despite published clinical standards and evidence-based “best practice” treatment guidelines, progress has been slow and uneven, and much remains to be done. The solution begins with recognizing that since cancer is personal, the “best care” must be defined one person at a time. Evidence-based treatment algorithms for specific types and stages of cancer are invaluable; however, quality requires tailoring treatments and plans of care to reflect the values, preferences, and priorities of the individual living with cancer. It takes a patient with his or her chosen family members and clinicians working together to determine the optimal plan of care at each particular point in time.

Conversations Matter Even a single conversation about end-of-life preferences between cancer patients and their physicians has been shown to improve the chances that people will be comfortable and not burdened with extraordinary treatments during their final days.11,12

Some people want all possible treatments to prolong life, regardless of discomfort; others set limits on the amount of discomfort and treatments they will accept. The right choice is one that is well considered and made by a well-informed person (and family) in collaboration with health-care professionals.

Don’t Take Quality for Granted The genuinely best doctors and medical centers have made care planning conversations and shared decision-making routine. They make it easy for people to get cutting-edge cancer treatments right along with the full services of a palliative care team. Truly excellent clinicians and health systems pay conscientious attention to transitions of care, seamlessly extending care to people’s homes and support to people’s family caregivers. If you or someone you love is living with cancer, it is wise to consider your options carefully. Talk with your doctor and with the people you trust to consider what types of treatment and overall care are right for you. Check the Dartmouth Atlas website (www.dartmouthatlas.org) to learn how the region you live in and the medical centers near you compare with others. Get that second, third, or fourth opinion, including one of a palliative care specialist. After all, this is personal. There is no reason to settle for less than the best. n

7 DRUG INTERACTIONS 7.1 Effects of Other Drugs on Vismodegib Drugs that Inhibit or Induce Drug Metabolizing Enzymes Vismodegib elimination involves multiple pathways. Vismodegib is predominantly excreted as an unchanged drug. Several minor metabolites are produced by multiple CYP enzymes. Although vismodegib is a substrate of CYP2C9 and CYP3A4 in vitro, CYP inhibition is not predicted to alter vismodegib systemic exposure since similar steady-state plasma vismodegib concentrations were observed in patients in clinical trials concomitantly treated with CYP3A4 inducers (i.e., carbamazepine, modafinil, phenobarbital) and those concomitantly treated with CYP3A4 inhibitors (i.e., erythromycin, fluconazole). Drugs that Inhibit Drug Transport Systems In vitro studies indicate that vismodegib is a substrate of the efflux transporter P-glycoprotein (P-gp). When ERIVEDGE is coadministered with drugs that inhibit P-gp (e.g. clarithromycin, erythromycin, azithromycin), systemic exposure of vismodegib and incidence of adverse events of ERIVEDGE may be increased. Drugs that Affect Gastric pH Drugs that alter the pH of the upper GI tract (e.g. proton pump inhibitors, H2-receptor antagonists, and antacids) may alter the solubility of vismodegib and reduce its bioavailability. However, no formal clinical study has been conducted to evaluate the effect of gastric pH altering agents on the systemic exposure of vismodegib. Increasing the dose of ERIVEDGE when coadministered with such agents is not likely to compensate for the loss of exposure. When ERIVEDGE is coadministered with a proton pump inhibitor, H2-receptor antagonist or antacid, systemic exposure of vismodegib may be decreased and the effect on efficacy of ERIVEDGE is unknown. 7.2 Effects of Vismodegib on Other Drugs Results of a drug-drug interaction study conducted in cancer patients demonstrated that the systemic exposure of rosiglitazone (a CYP2C8 substrate) or oral contraceptives (ethinyl estradiol and norethindrone) is not altered when either drug is co-administered with vismodegib. In vitro studies indicate that vismodegib is an inhibitor of CYP2C8, CYP2C9, CYP2C19 and the transporter BCRP. Vismodegib does not induce CYP1A2, CYP2B6, or CYP3A4/5 in human hepatocytes. 8 USE IN SPECIFIC POPULATIONS 8.1 Pregnancy Pregnancy Category D ERIVEDGE capsule can cause fetal harm when administered to a pregnant female based on its mechanism of action. Vismodegib is teratogenic in rats at doses corresponding to an exposure of 20% of the exposure at the recommended human dose (estimated AUC 0-24hr steady-state exposure). In rats, malformations included craniofacial anomalies, open perineum, and absent or fused digits. Fetal retardations and variations were also observed. Vismodegib is embryolethal in rats at exposures within the range achieved at the recommended human dose. If ERIVEDGE is used during pregnancy, or if the patient becomes pregnant while taking this drug, the patient should be apprised of the potential hazard to the embryo or fetus. Report immediately exposure to ERIVEDGE during pregnancy to the Genentech Adverse Event Line at 1-888-835-2555. Encourage women who may have been exposed to ERIVEDGE during pregnancy, either directly or through seminal fluid, to participate in the ERIVEDGE pregnancy pharmacovigilance program by contacting the Genentech Adverse Event Line at 1-888-835-2555 [see Boxed Warning, Warnings and Precautions (5.1)]. In an embryo-fetal developmental toxicity study, pregnant rats were administered oral vismodegib at doses of 10, 60, or 300 mg/kg/day during the period of organogenesis. Pre- and post-implantation loss were increased at doses of ≥ 60 mg/kg/day (approximately ≥ 2 times the systemic exposure (AUC) in patients at the recommended human dose), which included early resorption of 100% of the fetuses. A dose of 10 mg/kg/day (approximately 0.2 times the AUC in patients at the recommended dose) resulted in malformations (including missing and/or fused digits, open perineum and craniofacial anomalies) and retardations or variations (including dilated renal pelvis, dilated ureter, and incompletely or unossified sternal elements, centra of vertebrae, or proximal phalanges and claws). 8.3 Nursing Mothers It is not known whether vismodegib is excreted in human breast milk. Because many drugs are excreted in human milk and because

Female patients Determine pregnancy status within 7 days prior to initiation of treatment in females of reproductive potential. For females with a negative pregnancy test, initiate a highly effective form of contraception (failure rate of less than 1%) prior to the first dose. Continue highly effective contraception during therapy and for 7 months after the last dose of ERIVEDGE. If a patient becomes pregnant while taking ERIVEDGE, or during the 7 months after the last dose of treatment, report the pregnancy to the Genentech Adverse Event Line at 1-888-835-2555. Encourage pregnant females to participate in the ERIVEDGE pregnancy pharmacovigilance program by calling the Genentech Adverse Event Line at 1-888-835-2555. Counsel pregnant females about the teratogenic risk to the fetus. Amenorrhea has been observed in clinical trials in females of reproductive potential. Reversibility of amenorrhea is unknown [see Adverse Reactions (6), Nonclinical Toxicology (13.1)]. Male patients Male patients should use condoms with spermicide, even after a vasectomy, during sexual intercourse with female partners while being treated with ERIVEDGE capsule and for 2 months after the last dose to avoid exposing an embryo or fetus to vismodegib. 8.7 Hepatic Impairment The safety and effectiveness of ERIVEDGE capsule have not been established in patients with hepatic impairment [see Clinical Pharmacology (12.3)]. 8.8 Renal Impairment The safety and effectiveness of ERIVEDGE capsule have not been established in patients with renal impairment [see Clinical Pharmacology (12.3)]. 10 OVERDOSAGE There is no information on overdosage in humans. In clinical trials, ERIVEDGE capsule was administered at 540 mg orally once daily; exposure did not increase between 150 mg and 540 mg daily. 17 PATIENT COUNSELING INFORMATION See FDA-approved patient labeling (Medication Guide). • Advise patients that ERIVEDGE exposure during pregnancy can cause embryo-fetal death or severe birth defects. • Instruct female patients of reproductive potential to use a highly effective form of contraception (failure rate of less than 1%) while taking ERIVEDGE and for at least 7 months after the last dose of ERIVEDGE. • Instruct all male patients, even those with prior vasectomy, to use condoms with spermicide, during sexual intercourse with female partners while taking ERIVEDGE and for at least 2 months after the last dose of ERIVEDGE. • Instruct patients to immediately contact their healthcare provider if they (or, for males, their female partner) become pregnant or if pregnancy is suspected following exposure to ERIVEDGE. • Instruct patients to immediately report any pregnancy exposure to ERIVEDGE and encourage participation in the ERIVEDGE pregnancy pharmacovigilance program by calling the Genentech Adverse Event Line at 1-888-835-2555. • Inform female patients of the potential for serious adverse reactions in nursing infants from ERIVEDGE, taking into account the importance of the drug to the mother. • Advise patients not to donate blood or blood products while taking ERIVEDGE and for at least 7 months after the last dose of ERIVEDGE. • Advise patients to swallow ERIVEDGE capsules whole and not to crush or open the capsules.

1 INDICATIONS AND USAGE ERIVEDGE capsule is indicated for the treatment of adults with metastatic basal cell carcinoma, or with locally advanced basal cell carcinoma that has recurred following surgery or who are not candidates for surgery, and who are not candidates for radiation. 2 DOSAGE AND ADMINISTRATION The recommended dose of ERIVEDGE is 150 mg taken orally once daily until disease progression or until unacceptable toxicity [see Clinical Studies (14)]. ERIVEDGE may be taken with or without food. Swallow capsules whole. Do not open or crush capsules. If a dose of ERIVEDGE is missed, do not make up that dose; resume dosing with the next scheduled dose. 4 CONTRAINDICATIONS None. 5 WARNINGS AND PRECAUTIONS 5.1 Embryo-Fetal Death and Severe Birth Defects ERIVEDGE capsules can cause fetal harm when administered to a pregnant woman based on its mechanism of action. Vismodegib is teratogenic, embryotoxic, and fetotoxic in rats at maternal exposures lower than the human exposures at the recommended dose of 150 mg/day. In rats, malformations included craniofacial anomalies, open perineum, and absent or fused digits. Fetal retardations and variations were also observed. Verify pregnancy status prior to the initiation of ERIVEDGE. Advise male and female patients of the risks of embryo-fetal death and severe birth defects and the need for contraception during and after treatment. Advise patients to contact their healthcare provider immediately if they suspect they (or, for males, their female partner) may be pregnant. Female and male patients of reproductive potential should be counseled regarding pregnancy prevention and planning. If ERIVEDGE is used during pregnancy or if a patient becomes pregnant while taking (or for a male patient, if his female partner is exposed to) ERIVEDGE, the patient should be apprised of the potential hazard to the fetus. Report immediately exposure to ERIVEDGE during pregnancy to the Genentech Adverse Event Line at 1-888-835-2555. Encourage women who may have been exposed to ERIVEDGE during pregnancy, either directly or through seminal fluid, to participate in the ERIVEDGE pregnancy pharmacovigilance program by contacting the Genentech Adverse Event Line at 1-888-835-2555 [see Boxed Warning, Use in Specific Populations (8.1, 8.6)]. 5.2 Blood Donation Advise patients not to donate blood or blood products while receiving ERIVEDGE and for at least 7 months after the last dose of ERIVEDGE. 6 ADVERSE REACTIONS 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice. ERIVEDGE capsule was administered as monotherapy at doses ≥ 150 mg orally daily in four open-label, uncontrolled, dose-ranging or fixed single dose clinical trials enrolling a total of 138 patients with advanced basal cell carcinoma (BCC). The median age of these patients was 61 years (range 21 to 101), 100% were White (including Hispanics), and 64% were male. The median duration of treatment was approximately 10 months (305 days; range 0.7 to 36 months); 111 patients received ERIVEDGE for 6 months or longer. The most common adverse reactions (≥ 10%) were muscle spasms, alopecia, dysgeusia, weight loss, fatigue, nausea, diarrhea, decreased appetite, constipation, arthralgias, vomiting, and ageusia (Table 1).

of the potential for serious adverse reactions in nursing infants from ERIVEDGE, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother. 8.4 Pediatric Use The safety and effectiveness of ERIVEDGE capsule have not been established in pediatric patients. In repeat-dose toxicology studies in rats, administration of oral vismodegib resulted in toxicities in bone and teeth. Effects on bone consisted of closure of the epiphyseal growth plate when oral vismodegib was administered for 26 weeks at ≥ 50 mg/kg/day (approximately ≥ 0.4 times the systemic exposure (AUC) in patients at the recommended human dose). Abnormalities in growing incisor teeth (including degeneration/ necrosis of odontoblasts, formation of fluid-filled cysts in the dental pulp, ossification of the root canal, and hemorrhage resulting in breakage or loss of teeth) were observed after administration of oral vismodegib at ≥ 15 mg/kg/day (approximately ≥ 0.2 times the AUC in patients at the recommended human dose). 8.5 Geriatric Use Clinical studies of ERIVEDGE capsule did not include sufficient numbers of patients aged 65 and over to determine whether they respond differently from younger patients. 8.6 Females of Reproductive Potential and Males ERIVEDGE capsule can cause harm to the embryo or fetus when administered during pregnancy. Counsel female and male patients regarding pregnancy prevention and planning. Advise patients to contact their healthcare provider immediately if they suspect they (or, for males, their female partner) may be pregnant [see Boxed Warning, Warnings and Precautions (5.1), Use in Specific Populations (8.1)]

Evens, DO, MSc, Chief of Hematology/Oncology at Tufts University Medical Center, Boston, and colleagues examined treatment, complications, and outcomes for Hodgkin lymphoma (HL) and nonHodgkin lymphoma (NHL) occurring during pregnancy.1 The findings indicate that standard, non-antimetabolite, combination chemotherapy can be administered past the first trimester with few complications.

phoma diagnosis at a median of 22 weeks (range, 6–32 weeks; P < .001), with no difference in median time of diagnosis according to lymphoma type. Antenatal treatment was started in patients at a median of 25 weeks, with 89% receiving combination chemotherapy, most commonly with standard regimens for the particular lymphoma subtypes. Treatment was started in the second trimester in 37 patients (66%). The overall response rate for the 56 patients who received antenatal therapy was 82%, including complete response in 64%; overall response rate was 71% (complete response in 50%) in NHL

When clinically indicated, standard chemotherapy regimens for lymphoma administered during the second and third trimesters were associated with minimal maternal complications or fetal detriment. —Andrew M. Evens, DO, MSc, and colleagues

Study Details The study included 90 patients from 11 academic centers who had a diagnosis of NHL (n = 50) or HL (n = 40) during pregnancy over a 13year period (1999–2011). Patients had a median age of 30 years (range, 18–44 years) and median diagnosis occurred at 24 weeks’ gestation. Advanced-stage disease was present in 52% of patients with NHL and 25% of those with HL (P = .01). Of patients with stage I to II disease, 17% of patients with NHL and 30% of patients with HL had B symptoms or bulky disease.

Treatment Details and Outcome Among the 90 patients, pregnancy was terminated in 6 (7%) to permit immediate chemotherapy. Among the other 84 patients, 28 (33%)—including 32% of NHL patients and 35% of HL patents—had therapy deferred to postpartum; these patients were diagnosed with lymphoma at a median of 30 weeks’ gestation (range, 12–38 weeks). The 56 patients (67%) who received antenatal treatment had lym-

patients and 96% (complete response in 83%) in HL patients (P = .03 for overall response rate, P = .013 for complete response).

Complications The most common complication was induction of labor, in 33% of patients. Perinatal events included premature rupture of membranes in 13% and preeclampsia in 7%. Delivery was via cesarean section in 33% of patients, with such delivery occurring in more NHL patients (44% vs 19%, P = .007). Among the 83 patients for whom timing of delivery was available, 44% had preterm deliveries with no difference based on NHL vs HL (51% vs 36%, P = .19).

Fetal Outcomes The median gestation at delivery was 37 weeks (range, 31–40 weeks). Gestation went to full term in 47 (56%) of 84 patients, with no differences according to lymphoma type or receipt of antenatal therapy. One miscarriage occurred at 19 weeks’ gestation in a 34-year-old patient with double-hit NHL following one cycle of R-CHOP (rituximab [Rituxan] plus cyclophosphamide, doxorubicin, vincristine, and pred-

Impact of Lymphoma on Pregnancy ■■ As stated by the investigators: “Standard (non-antimetabolite) combination chemotherapy administered past the first trimester, as early as 13 weeks’ gestation, was associated with few complications and expected maternal [and fetal] survival with lymphoma occurring during pregnancy.”

■■ In mothers with NHL, radiotherapy predicted inferior progression-free

survival and poor ECOG performance status and increased lactate dehydrogenase predicted inferior overall survival. In mothers with HL, multiparous status predicted improved progression-free survival and presence of B symptoms at diagnosis predicted inferior progression-free survival.

nisone). The median birth weight was 2,668 g (range, 1,005–3,628 g). Although there was no difference in birth weight according to receipt of antenatal chemotherapy vs deferred therapy (2,670 g vs 2,665 g, P = .74), there was a trend for infants to be small for gestational age if their mothers had received antenatal therapy (41% vs 9%, P = .09). Of gestations for which information was available, 8 (11%) of 72 infants, all born to NHL patients, required admission to the neonatal intensive care unit (median stay, 12 days; range, 3–40 days), with no differences based on antenatal therapy vs deferred therapy. Microcephaly was reported in one infant following four antenatal cycles of CHOP for diffuse large B-cell lymphoma in the mother, who started treatment at 28 weeks’ gestation and delivered at 38 weeks. Grade 1 pelviectasis occurred in an infant whose mother received four antenatal cycles of R-CHOP for diffuse large B-cell lymphoma at 21 weeks’ gestation and delivered at 34 weeks due to preeclampsia. No other malformations were detected.

Maternal Outcomes At a median follow-up of 41 months (range, 6–147 months), 3-year progression-free survival and overall survival rates were 53% and 82% for NHL patients and 85% and 97% for HL patients; rates were 55% and 79% for diffuse large B-cell lymphoma patients and 37% and 90% for patients with Tcell NHL (P = .43 and P = .60, respectively). There were 8 deaths related to NHL, including 5 due to diffuse large B-cell lymphoma, 1 due to peripheral T-cell lymphoma–not otherwise specified, 1 due to Burkitt’s lymphoma, and 1 due to double-hit NHL. In NHL patients, radiotherapy

was the only predictor of inferior progression-free survival (hazard ratio [HR] = 5.19, P = .003) and Eastern Cooperative Oncology Group (ECOG) performance status of 2 to 4 (HR = 5.51, P = .001) and increased lactate dehydrogenase (HR = 9.93, P = .03) predicted inferior overall survival. For patients with diffuse large B-cell lymphoma, radiotherapy predicted inferior progression-free survival (HR = 7.72, P = .008) and poor ECOG performance status predicted worse overall survival (HR = 2.33, P = .04). For patients with HL, multiparous status predicted improved progression-free survival (HR = 0.07, P = .01), presence of B symptoms at diagnosis predicted inferior progression-free survival (HR = 10.78, P = .04), and no variables were predictive of overall survival. Dr. Evens told The ASCO Post that “When clinically indicated, standard chemotherapy regimens for lymphoma administered during the second and third trimesters were associated with minimal maternal complications or fetal detriment.” In addition, Dr. Evens indicated there were lowrisk clinical scenarios with low tumor burden or late gestational diagnosis, where therapy was safely deferred to postpartum. And in all cases, he said it is critical that care be closely coordinated with high-risk maternal-fetal medicine.n Disclosure: Dr. Evans reported no potential conflicts of interest.

Two Patients in One, Mom and Baby: Managing Coincident Pregnancy and Lymphoma By Joseph M. Connors, MD

T

he news that she is both pregnant and has been found to have a potentially lethal malignancy is one of the most emotionally wrenching events any young woman ever faces. Understandably, the patient, her partner, their families, and even their caregivers find this experience fraught with anxiety and fear. Being able to provide solid information and a sensible plan of management is a major responsibility of the woman’s oncologist. All of us who fulfill this role should be grateful for the thoroughgoing analysis provided by Dr. Andrew Evens and his colleagues in their recent publication in the Journal of Clinical Oncology,1 as reviewed in this issue of The ASCO Post. As with any retrospective collection of special cases from multiple institutions gathered over many years of experience, however, the reader must be careful not to overinterpret the validity of the results. The authors describe the clinical course of 90 pregnant patients found to have either non-Hodgkin lymphoma (NHL, n = 50) or Hodgkin lymphoma (HL, n = 40) and were able to make several very important observations. Observation #1: Pregnancies encountered coincident with lymphoma do not need to be terminated. Two patients already had lymphoma when they became pregnant. Of 11 patients diagnosed in the first trimester of pregnancy, 6 elected to terminate the pregnancy, and treatment was deferred until later in the remaining 5. This is important because major organogenesis is mostly completed during the first trimester, when treatments could be likely to cause major birth defects. After the first trimester, treatments may be tolerated and not likely to cause fetal harm. Most patients were diagnosed in the second or third trimester (79/88, 90%). The large majority (83/84, 99%) of patients who chose Dr. Connors is Clinical Director, BC Cancer Agency Centre for Lymphoid Cancer, Vancouver, British Columbia.

to keep the pregnancy successfully reached term delivery. Observation #2: Intervention is not necessary unless the lymphoma is symptomatic or of a histologic type that threatens rapid progression. Treatment was deferred until after delivery in 28 patients, primarily those with HL or indolent NHL (HL: 13/40; follicular NHL: 4/5). Deferral of treatment in asymptomatic patients does not appear to jeopardize the

patients were able to defer delivery until good fetal maturation was achieved, which was also reflected in the low rate of admission to a neonatal intensive care unit (11%). Early induction of delivery is unnecessary unless fetal distress or major complications develop, and is seldom needed. Observation #5: The infants born to women with coincident pregnancy and lymphoma do well. Although gestational age was lower than the 10th percentile in 23% of in-

mother or child. Thus, only 56 of the 90 patients required intervention, and neither fetal nor maternal outcomes appear to have been negatively impacted by deferral of treatment until after delivery in the 28 patients so managed. Observation #3: When treatment is required, standard regimens are acceptable. Most patients received standard regimens such as CHOP (cyclophosphamide, doxorubicin, vincristine, and prednisone) with or without rituximab (Rituxan) for NHL and ABVD (doxorubicin, bleomycin, vinblastine, dacarbazine) for HL. Appropriately, very few patients received radiation (NHL: 5, HL: 4), which should be avoided because scatter radiation reaches the uterus in significant amounts, especially during the late phases of pregnancy. Observation #4: Term delivery is both desirable and regularly achievable. Median gestation at delivery was 37 weeks with 56% of patients delivering at full term, indicating that most

fants, the median birth weight of 2,668 g was in the normal range (> 2,500 g), and neonatal intensive care was seldom needed (11%); only two (2%) fetal malformations were seen. Observation #6: The mothers do well. Although the small numbers of patients, the diverse mix of histologic types, and wide distribution of prognostic factors limit conclusions, the outcome of treatment is roughly comparable to that seen in nonpregnant women. Progression-free and overall survival rates at 3 years were 55% and 79% for diffuse large B-cell lymphoma and 85% and 97% for HL, respectively.

More importantly, no long-term follow-up of the children is provided. Firm conclusions about their well-being cannot be drawn. While the low fetal malformation rate is reassuring, none of the fetuses was exposed to treatment during the first trimester. Furthermore, no one should be complacent about the potential for late consequences in children who are exposed to highly cytotoxic chemicals during fetal development. Deferral of treatment remains the best choice for asymptomatic patients with less threatening types of lymphoma such as HL and indolent NHL. None of the patients was managed with minimal chemotherapy such as single-agent vinblastine for HL with deferral of multiagent regimens until after delivery, a strategy that has been employed with success by other authorities,2 and this approach should not be dismissed. Finally, all patients were managed by a sophisticated multidisciplinary team, an approach that should be considered mandatory for this challenging clinical situation.

Conclusion Women, their partners, and their families will continue to be frightened and anxious when pregnancy and lymphoma coincide. Armed with the information provided in this excellent study and the literature reviewed by the authors, the clinical team can provide guarded reassurance that treatment deferral if possible, and standard treatment if necessary, will allow successful term delivery of a normal child and likely cure of the lymphoma for most patients. n

Disclosure: Dr. Connors reported no potential conflicts of interest.

Cautionary Remarks These results describing the outcome of coincident lymphoma and pregnancy are very encouraging. However, several cautions are necessary. First, even though this series is the largest and best reported to date, it is still small and heterogeneous. Followup of the mothers is reasonably, but not completely, mature (median, 41 months; range, 6–147 months).

Brief Summary of Prescribing Information. See full prescribing information for complete product information. 1 INDICATIONS AND USAGE AFINITOR® is indicated for the treatment of postmenopausal women with advanced hormone receptor-positive, HER2-negative breast cancer (advanced HR+ BC) in combination with exemestane, after failure of treatment with letrozole or anastrozole. 4 CONTRAINDICATIONS AFINITOR is contraindicated in patients with hypersensitivity to the active substance, to other rapamycin derivatives, or to any of the excipients. Hypersensitivity reactions manifested by symptoms including, but not limited to, anaphylaxis, dyspnea, flushing, chest pain, or angioedema (e.g., swelling of the airways or tongue, with or without respiratory impairment) have been observed with everolimus and other rapamycin derivatives. 5 WARNINGS AND PRECAUTIONS Non-infectious Pneumonitis Non-infectious pneumonitis is a class effect of rapamycin derivatives, including AFINITOR. Non-infectious pneumonitis was reported in up to 19% of patients treated with AFINITOR in clinical trials. The incidence of Common Terminology Criteria (CTC) grade 3 and 4 non-infectious pneumonitis was up to 4.0% and up to 0.2%, respectively [see Adverse Reactions (6.1, 6.2, 6.3, 6.4, 6.5) in the full prescribing information]. Fatal outcomes have been observed. Consider a diagnosis of non-infectious pneumonitis in patients presenting with non-specific respiratory signs and symptoms such as hypoxia, pleural effusion, cough, or dyspnea, and in whom infectious, neoplastic, and other causes have been excluded by means of appropriate investigations. Advise patients to report promptly any new or worsening respiratory symptoms. Patients who develop radiological changes suggestive of non-infectious pneumonitis and have few or no symptoms may continue AFINITOR therapy without dose alteration. Imaging appears to overestimate the incidence of clinical pneumonitis. If symptoms are moderate, consider interrupting therapy until symptoms improve. The use of corticosteroids may be indicated. AFINITOR may be reintroduced at a daily dose approximately 50% lower than the dose previously administered [see Table 1 in Dosage and Administration (2.2) in the full prescribing information]. For cases of grade 4 non-infectious pneumonitis, discontinue AFINITOR. Corticosteroids may be indicated until clinical symptoms resolve. For cases of grade 3 non-infectious pneumonitis interrupt AFINITOR until resolution to less than or equal to grade 1. AFINITOR may be re-introduced at a daily dose approximately 50% lower than the dose previously administered depending on the individual clinical circumstances [see Table 1 in Dosage and Administration (2.2) in the full prescribing information]. If toxicity recurs at grade 3, consider discontinuation of AFINITOR. The development of pneumonitis has been reported even at a reduced dose. Infections AFINITOR has immunosuppressive properties and may predispose patients to bacterial, fungal, viral, or protozoal infections, including infections with opportunistic pathogens [see Adverse Reactions (6.1, 6.2, 6.3, 6.4, 6.5) in the full prescribing information]. Localized and systemic infections, including pneumonia, mycobacterial infections, other bacterial infections, invasive fungal infections, such as aspergillosis or candidiasis, and viral infections including reactivation of hepatitis B virus have occurred in patients taking AFINITOR. Some of these infections have been severe (e.g., leading to respiratory or hepatic failure) or fatal. Physicians and patients should be aware of the increased risk of infection with AFINITOR. Complete treatment of pre-existing invasive fungal infections prior to starting treatment with AFINITOR. While taking AFINITOR, be vigilant for signs and symptoms of infection; if a diagnosis of an infection is made, institute appropriate treatment promptly and consider interruption or discontinuation of AFINITOR. If a diagnosis of invasive systemic fungal infection is made, discontinue AFINITOR and treat with appropriate antifungal therapy. Oral Ulceration Mouth ulcers, stomatitis, and oral mucositis have occurred in patients treated with AFINITOR at an incidence ranging from 44-86% across the clinical trial experience. Grade 3 or 4 stomatitis was reported in 4-9% of patients [see Adverse Reactions (6.1, 6.2, 6.3, 6.4, 6.5) in the full prescribing information]. In such cases, topical treatments are recommended, but alcohol-, peroxide-, iodine-, or thyme-containing mouthwashes should be avoided as they may exacerbate the condition. Antifungal agents should not be used unless fungal infection has been diagnosed [see Drug Interactions]. Renal Failure Cases of renal failure (including acute renal failure), some with a fatal outcome, have been observed in patients treated with AFINITOR [see Laboratory Tests and Monitoring].

Geriatric Patients In the randomized advanced hormone receptor-positive, HER2-negative breast cancer study, the incidence of deaths due to any cause within 28 days of the last AFINITOR dose was 6% in patients ≥ 65 years of age compared to 2% in patients < 65 years of age. Adverse reactions leading to permanent treatment discontinuation occurred in 33% of patients ≥ 65 years of age compared to 17% in patients < 65 years of age. Careful monitoring and appropriate dose adjustments for adverse reactions are recommended [see Dosage and Administration (2.2) in the full prescribing information, Use in Specific Populations]. Laboratory Tests and Monitoring Renal Function Elevations of serum creatinine and proteinuria have been reported in clinical trials [see Adverse Reactions (6.1, 6.2, 6.3, 6.4, 6.5) in the full prescribing information]. Monitoring of renal function, including measurement of blood urea nitrogen (BUN), urinary protein, or serum creatinine, is recommended prior to the start of AFINITOR therapy and periodically thereafter. Blood Glucose and Lipids Hyperglycemia, hyperlipidemia, and hypertriglyceridemia have been reported in clinical trials [see Adverse Reactions (6.1, 6.2, 6.3, 6.4, 6.5) in the full prescribing information]. Monitoring of fasting serum glucose and lipid profile is recommended prior to the start of AFINITOR therapy and periodically thereafter. When possible, optimal glucose and lipid control should be achieved before starting a patient on AFINITOR. Hematologic Parameters Decreased hemoglobin, lymphocytes, neutrophils, and platelets have been reported in clinical trials [see Adverse Reactions (6.1, 6.2, 6.3, 6.4, 6.5) in the full prescribing information]. Monitoring of complete blood count is recommended prior to the start of AFINITOR therapy and periodically thereafter. Drug-drug Interactions Due to significant increases in exposure of everolimus, co-administration with strong CYP3A4 inhibitors should be avoided [see Dosage and Administration (2.2, 2.5) in the full prescribing information and Drug Interactions]. A reduction of the AFINITOR dose is recommended when co-administered with a moderate CYP3A4 and/or PgP inhibitor [see Dosage and Administration (2.2, 2.5) in the full prescribing information and Drug Interactions]. An increase in the AFINITOR dose is recommended when co-administered with a strong CYP3A4 inducer [see Dosage and Administration (2.2, 2.5) in the full prescribing information and Drug Interactions]. Hepatic Impairment Exposure to everolimus was increased in patients with hepatic impairment [see Clinical Pharmacology (12.3) in the full prescribing information]. For advanced HR+ BC, advanced PNET, advanced RCC, and renal angiomyolipoma with TSC patients with severe hepatic impairment (Child-Pugh class C), AFINITOR may be used at a reduced dose if the desired benefit outweighs the risk. For patients with mild (Child-Pugh class A) or moderate (Child-Pugh class B) hepatic impairment, a dose reduction is recommended [see Dosage and Administration (2.2) and Clinical Pharmacology (12.3) in the full prescribing information]. For patients with SEGA and mild or moderate hepatic impairment, adjust the dose of AFINITOR Tablets based on therapeutic drug monitoring. For patients with SEGA and severe hepatic impairment, reduce the starting dose of AFINITOR Tablets by approximately 50% and adjust subsequent doses based on therapeutic drug monitoring [see Dosage and Administration (2.4, 2.5) in the full prescribing information]. Vaccinations During AFINITOR treatment, avoid the use of live vaccines and avoid close contact with individuals who have received live vaccines (e.g., intranasal influenza, measles, mumps, rubella, oral polio, BCG, yellow fever, varicella, and TY21a typhoid vaccines). For pediatric patients with SEGA that do not require immediate treatment, complete the recommended childhood series of live virus vaccinations according to American Council on Immunization Practices (ACIP) guidelines prior to the start of therapy. An accelerated vaccination schedule may be appropriate. Embryo-fetal Toxicity There are no adequate and well-controlled studies of AFINITOR in pregnant women; however, based on the mechanism of action, AFINITOR can cause fetal harm. Everolimus caused embryo-fetal toxicities in animals at maternal exposures that were lower than human exposures. If this drug is used during pregnancy or if the patient becomes pregnant while taking this drug, the patient should be apprised of the potential hazard to a fetus. Women of childbearing potential should be advised to use a highly effective method of contraception while using AFINITOR and for up to 8 weeks after ending treatment [see Use in Specific Populations]. 6 ADVERSE REACTIONS The efficacy and safety of AFINITOR (10 mg/day) plus exemestane (25 mg/day) (n=485) versus placebo plus exemestane (25 mg/day) (n=239) was evaluated in a randomized, controlled trial in patients with advanced or metastatic hormone receptor-positive, HER2-negative breast cancer. The median age of patients was 61 years (range 28-93), and 75% were Caucasian. Safety results are based on a median follow-up of approximately 13 months.


The most common adverse reactions (incidence ≥ 30%) were stomatitis, infections, rash, fatigue, diarrhea, and decreased appetite. The most common grade 3/4 adverse reactions (incidence ≥ 2%) were stomatitis, infections, hyperglycemia, fatigue, dyspnea, pneumonitis, and diarrhea. The most common laboratory abnormalities (incidence ≥ 50%) were hypercholesterolemia, hyperglycemia, increased AST, anemia, leukopenia, thrombocytopenia, lymphopenia, increased ALT, and hypertriglyceridemia. The most common grade 3/4 laboratory abnormalities (incidence ≥ 3%) were lymphopenia, hyperglycemia, anemia, decreased potassium, increased AST, increased ALT, and thrombocytopenia. Fatal adverse reactions occurred more frequently in patients who received AFINITOR plus exemestane (2%) compared to patients on the placebo plus exemestane arm (0.4%). The rates of treatment-emergent adverse events resulting in permanent discontinuation were 24% and 5% for the AFINITOR plus exemestane and placebo plus exemestane treatment groups, respectively. Dose adjustments (interruptions or reductions) were more frequent among patients in the AFINITOR plus exemestane arm than in the placebo plus exemestane arm (63% versus 14%). Table 2 compares the incidence of treatment-emergent adverse reactions reported with an incidence of ≥10% for patients receiving AFINITOR 10 mg daily versus placebo.

In vitro, everolimus is a competitive inhibitor of CYP3A4 and a mixed inhibitor of CYP2D6. Agents That May Increase Everolimus Blood Concentrations CYP3A4 Inhibitors and PgP Inhibitors In healthy subjects, compared to AFINITOR treatment alone there were significant increases in everolimus exposure when AFINITOR was coadministered with: • ketoconazole (a strong CYP3A4 inhibitor and a PgP inhibitor) - Cmax and AUC increased by 3.9- and 15.0-fold, respectively. • erythromycin (a moderate CYP3A4 inhibitor and a PgP inhibitor) - Cmax and AUC increased by 2.0- and 4.4-fold, respectively. • verapamil (a moderate CYP3A4 inhibitor and a PgP inhibitor) - Cmax and AUC increased by 2.3- and 3.5-fold, respectively. Concomitant strong inhibitors of CYP3A4 should not be used [see Dosage and Administration (2.2, 2.5) in the full prescribing information and Warnings and Precautions]. Use caution when AFINITOR is used in combination with moderate CYP3A4 and/or PgP inhibitors. If alternative treatment cannot be administered reduce the AFINITOR dose [see Dosage and Administration (2.2, 2.5) in the full prescribing information and Warnings and Precautions]. Agents That May Decrease Everolimus Blood Concentrations CYP3A4 Inducers In healthy subjects, co-administration of AFINITOR with rifampin, a strong inducer of CYP3A4, decreased everolimus AUC and Cmax by 63% and 58% respectively, compared to everolimus treatment alone. Consider a dose increase of AFINITOR when co-administered with strong CYP3A4 inducers if alternative treatment cannot be administered. St. John’s Wort may decrease everolimus exposure unpredictably and should be avoided [see Dosage and Administration (2.2, 2.5) in the full prescribing information]. Drugs That May Have Their Plasma Concentrations Altered by Everolimus Studies in healthy subjects indicate that there are no clinically significant pharmacokinetic interactions between AFINITOR and the HMG-CoA reductase inhibitors atorvastatin (a CYP3A4 substrate) and pravastatin (a non-CYP3A4 substrate) and population pharmacokinetic analyses also detected no influence of simvastatin (a CYP3A4 substrate) on the clearance of AFINITOR.

A study in healthy subjects demonstrated that co-administration of an oral dose of midazolam (sensitive CYP3A4 substrate) with everolimus resulted in a 25% increase in midazolam Cmax and a 30% increase in midazolam AUC(0-inf). Coadministration of everolimus and exemestane increased exemestane Cmin by 45% and C2h by 64%. However, the corresponding estradiol levels at steady state (4 weeks) were not different between the two treatment arms. No increase in adverse events related to exemestane was observed in patients with hormone receptor-positive, HER2-negative advanced breast cancer receiving the combination. Coadministration of everolimus and depot octreotide increased octreotide Cmin by approximately 50%. 8 USE IN SPECIFIC POPULATIONS Pregnancy Pregnancy Category D [see Warnings and Precautions]. There are no adequate and well-controlled studies of AFINITOR in pregnant women; however, based on the mechanism of action, AFINITOR can cause fetal harm when administered to a pregnant woman. Everolimus caused embryo-fetal toxicities in animals at maternal exposures that were lower than human exposures. If this drug is used during pregnancy or if the patient becomes pregnant while taking the drug, the patient should be apprised of the potential hazard to the fetus. Women of childbearing potential should be advised to use a highly effective method of contraception while receiving AFINITOR and for up to 8 weeks after ending treatment. In animal reproductive studies, oral administration of everolimus to female rats before mating and through organogenesis induced embryo-fetal toxicities, including increased resorption, pre-implantation and post-implantation loss, decreased numbers of live fetuses, malformation (e.g., sternal cleft), and retarded skeletal development. These effects occurred in the absence of maternal toxicities. Embryo-fetal toxicities in rats occurred at doses ≥ 0.1 mg/kg (0.6 mg/m2) with resulting exposures of approximately 4% of the exposure (AUC0-24h) achieved in patients receiving the 10 mg daily dose of everolimus. In rabbits, embryotoxicity evident as an increase in resorptions occurred at an oral dose of 0.8 mg/kg (9.6 mg/m2), approximately 1.6 times either the 10 mg daily dose or the median dose administered to SEGA patients on a body surface area basis. The effect in rabbits occurred in the presence of maternal toxicities. In a pre- and post-natal development study in rats, animals were dosed from implantation through lactation. At the dose of 0.1 mg/kg (0.6 mg/m2), there were no adverse effects on delivery and lactation or signs of maternal toxicity; however, there were reductions in body weight (up to 9% reduction from the control) and in survival of offspring (~5% died or missing). There were no drug-related effects on the developmental parameters (morphological development, motor activity, learning, or fertility assessment) in the offspring. Nursing Mothers It is not known whether everolimus is excreted in human milk. Everolimus and/or its metabolites passed into the milk of lactating rats at a concentration 3.5 times higher than in maternal serum. Because many drugs are excreted in human milk and because of the potential for serious adverse reactions in nursing infants from everolimus, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother. Pediatric Use Pediatric use of AFINITOR Tablets is recommended for patients 1 year of age and older with TSC for the treatment of SEGA that requires therapeutic intervention but cannot be curatively resected. The safety and effectiveness of AFINITOR Tablets have not been established in pediatric patients with renal angiomyolipoma with TSC in the absence of SEGA. The effectiveness of AFINITOR in pediatric patients with SEGA was demonstrated in two clinical trials based on demonstration of durable objective response, as evidenced by reduction in SEGA tumor volume [see Clinical Studies (14.5) in the full prescribing information]. Improvement in diseaserelated symptoms and overall survival in pediatric patients with SEGA has not been demonstrated. The long term effects of AFINITOR on growth and pubertal development are unknown. Study 1 was a randomized, double-blind, multicenter trial comparing AFINITOR (n=78) to placebo (n=39) in pediatric and adult patients. The median age was 9.5 years (range 0.8 to 26 years). At the time of randomization, a total of 20 patients were < 3 years of age, 54 patients were 3 to < 12 years of age, 27 patients were 12 to < 18 years of age, and 16 patients were ≥ 18 years of age. The overall nature, type, and frequency of adverse reactions across the age groups evaluated were similar, with the exception of a higher per patient incidence of infectious serious adverse events in patients < 3 years of age. A total of 6 of 13 patients (46%) < 3 years of age had at least one serious adverse event due to infection, compared to 2 of 7 patients (29%) treated with placebo. No patient in any age group discontinued AFINITOR due to infection [see Adverse Reactions (6.5) in the full prescribing information]. Subgroup analyses showed reduction in SEGA volume with AFINITOR treatment in all pediatric age subgroups.

Study 2 was an open-label, single-arm, single-center trial of AFINITOR (N=28) in patients aged ≥ 3 years; median age was 11 years (range 3 to 34 years). A total of 16 patients were 3 to < 12 years, 6 patients were 12 to < 18 years, and 6 patients were ≥ 18 years. The frequency of adverse reactions across the age groups was generally similar [see Adverse Reactions (6.5) in the full prescribing information]. Subgroup analyses showed reductions in SEGA volume with AFINITOR treatment in all pediatric age subgroups. Everolimus clearance normalized to body surface area was higher in pediatric patients than in adults with SEGA [see Clinical Pharmacology (12.3) in the full prescribing information].The recommended starting dose and subsequent requirement for therapeutic drug monitoring to achieve and maintain trough concentrations of 5 to 15 ng/mL are the same for adult and pediatric patients with SEGA [see Dosage and Administration (2.3, 2.4) in the full prescribing information]. Geriatric Use In the randomized advanced hormone receptor positive, HER2-negative breast cancer study, 40% of AFINITOR-treated patients were ≥ 65 years of age, while 15% were 75 and over. No overall differences in effectiveness were observed between elderly and younger subjects. The incidence of deaths due to any cause within 28 days of the last AFINITOR dose was 6% in patients ≥ 65 years of age compared to 2% in patients < 65 years of age. Adverse reactions leading to permanent treatment discontinuation occurred in 33% of patients ≥ 65 years of age compared to 17% in patients < 65 years of age [see Warnings and Precautions]. In two other randomized trials (advanced renal cell carcinoma and advanced neuroendocrine tumors of pancreatic origin), no overall differences in safety or effectiveness were observed between elderly and younger subjects. In the randomized advanced RCC study, 41% of AFINITOR treated patients were ≥ 65 years of age, while 7% were 75 and over. In the randomized advanced PNET study, 30% of AFINITOR-treated patients were ≥ 65 years of age, while 7% were 75 and over. Other reported clinical experience has not identified differences in response between the elderly and younger patients, but greater sensitivity of some older individuals cannot be ruled out [see Clinical Pharmacology (12.3) in the full prescribing information]. No dosage adjustment in initial dosing is required in elderly patients, but close monitoring and appropriate dose adjustments for adverse reactions is recommended [see Dosage and Administration (2.2), Clinical Pharmacology (12.3) in the full prescribing information]. Renal Impairment No clinical studies were conducted with AFINITOR in patients with decreased renal function. Renal impairment is not expected to influence drug exposure and no dosage adjustment of everolimus is recommended in patients with renal impairment [see Clinical Pharmacology (12.3) in the full prescribing information]. Hepatic Impairment The safety, tolerability and pharmacokinetics of AFINITOR were evaluated in a 34 subject single oral dose study of everolimus in subjects with impaired hepatic function relative to subjects with normal hepatic function. Exposure was increased in patients with mild (Child-Pugh class A), moderate (Child-Pugh class B), and severe (Child-Pugh class C) hepatic impairment [see Clinical Pharmacology (12.3) in the full prescribing information]. For advanced HR+ BC, advanced PNET, advanced RCC, and renal angiomyolipoma with TSC patients with severe hepatic impairment, AFINITOR may be used at a reduced dose if the desired benefit outweighs the risk. For patients with mild (Child-Pugh class A) or moderate (Child-Pugh class B) hepatic impairment, a dose reduction is recommended [see Dosage and Administration (2.2) in the full prescribing information]. For patients with SEGA who have severe hepatic impairment (Child-Pugh class C), reduce the starting dose of AFINITOR Tablets by approximately 50%. For patients with SEGA who have mild (Child-Pugh class A) or moderate (ChildPugh class B) hepatic impairment, adjustment to the starting dose may not be needed. Subsequent dosing should be based on therapeutic drug monitoring [see Dosage and Administration (2.4, 2.5) in the full prescribing information]. 10 OVERDOSAGE In animal studies, everolimus showed a low acute toxic potential. No lethality or severe toxicity was observed in either mice or rats given single oral doses of 2000 mg/kg (limit test). Reported experience with overdose in humans is very limited. Single doses of up to 70 mg have been administered. The acute toxicity profile observed with the 70 mg dose was consistent with that for the 10 mg dose.

High-Dose Spinal Stereotactic Body Radiotherapy Associated With Increased Risk of Vertebral Compression Fracture By Eric Lis, MD

A

s reviewed in this issue of The ASCO Post, Sahgal et al reported a multi-institutional analysis aimed at clarifying the risk of developing either new or progressive vertebral body compression fractures following high-dose spinal stereotactic body radiation therapy. In the period studied, they encountered 57 vertebral compression fractures out of 410 vertebrae that were treated with such therapy (14%). They report that vertebrae at risk for collapse included those with a baseline vertebral compression fracture, lytic disease, or malalignment, and that caution should be taken when treating such lesions with doses ≥ 20 Gy/fraction.

Positive Perspective I tend to look at this well-written paper in a positive light in that there were only 57 vertebral compression fractures out of the 410 segments treated, and of those 57 vertebral compression fractures, only 24 required further interventions, of which 18 had minimally invasive procedures. Dr. Lis is Director of Interventional Neuroradiology, Memorial Sloan-Kettering Cancer Center, New York.

Thus, the majority of the vertebral compression fractures encountered required no further intervention. The authors comment that highdose single-fraction stereotactic body radiotherapy (≥ 20 Gy/fraction) may

with or without percutaneous instrumentation. To put it another way, it is usually easier to handle a vertebral compression fracture in the setting of nonviable tumor treated with high-dose singlefraction stereotactic body radiotherapy (≥ 20 Gy/fraction) than it is to treat a recurrent metastasis that has been treated with < 20 Gy/fraction.

Conclusion In summary, this paper further identifies risks for vertebral compression fracture associated with spine stereotactic radiosurgery, especially regarding lesions treated with highdose single-fraction stereotactic body radiotherapy (≥ 20 Gy/fraction). I contend that the risk of vertebral compression fracture associated with such treatment is outweighed by the benefit of local tumor control and that it is far easier to palliate a vertebral compression fracture without tumor progression than it is to deal with the complications associated with active tumor recurrence—which frequently include vertebral compression fractures anyway. n

In the research of advanced cancers

What if inhibiting the PD-1 checkpoint pathway played an important role in restoring immune response to tumor cells? In a normal state, the immune system recognizes tumors and can mount an active antitumor response1,2 Antigen-presenting cell

Step 1:

Active T cells

Step 2:

Antigen-presenting cells activate T cells that proliferate and migrate to the tumor. T cells then release apoptosisinducing proteins, which attack the tumor cells3,4

Vertebral Compression Fracture Risk continued from page 90

tebral segment was scored according to the SINS criteria. Additional factors analyzed included histologic type, paraspinal/epidural disease extension, whether any targeted therapy or bisphosphonates had been given within 2 months before stereotactic body radiotherapy, prior radiation to the treated segment, total dose prescribed, number of fractions, and whether the treated segment included other adjacent segments in the target volume (single vs multiple).

Fracture Incidence Median follow-up was 11.5 months (range, 0.03–113 months). Median and mean overall survival were 16 and 26 months, respectively. A total of 57 vertebral compression fractures were identified (14% of spinal segments), consisting of 27 new fractures (47% of fractures) and 30 fracture progressions. Median time to vertebral compression fracture was 2.46 months (range, 0.03–43.01 months), with 65% occurring within the first 4 months after stereotactic body radiotherapy. The 1- and 2-year cumulative rates of fracture were 12.35% and 13.49%, respectively. Mean age was 57 years for patients with and without fractures. Of the 57 fractures, 26 each occurred in the thoracic and lumbar spine and 5 occurred in the cervical spine. Paraspinal/epidural disease was present in 38 cases. Patients were receiving targeted systemic therapy and bisphosphonates in 31 and 14 cases, respectively, and had received prior radiation in 7 cases. There

was a single segment target in 43 cases. Radiation dose/fraction was < 8 Gy in 4 cases, 8 to 11 Gy in 13, 12 to 19 Gy in 22, 20 to 23 Gy in 6, and ≥ 24 Gy in 12. Bone lesion types were lytic in 48 cases, mixed in 6, and blastic in 3. In 47 cases, patients had normal spinal alignment, with kyphosis/scoliosis present in 9 and subluxation/translation present in 1. Vertebral body collapse was present in 30 cases, with ≥ 50% vertebral body involvement in 3 and < 50% in 27; no collapse but > 50% of vertebral body involvement with the tumor was present in 13 cases. SINS classification was stable in 13 cases, indeterminate in 42, and unstable in 2.

Predictors of Fracture On multivariate analysis, radiation dose/fraction and baseline vertebral compression fracture, presence of a lytic tumor, and spinal deformity (3 of the 6 SINS criteria) were significant predictors of vertebral compression fracture. For baseline vertebral body collapse, compared with no vertebral compression fracture and < 50% vertebral body involvement, hazard ratios were 6.92 (P = .0189) for ≥ 50% vertebral compression fracture, 8.98 (P < .001) for < 50% vertebral compression fracture, and 4.96 (P < .001) for no vertebral compression fracture but > 50% of vertebral body involved. Compared with radiation dose/ fraction ≤ 19 Gy, hazard ratios were 5.25 (P < .001) for ≥ 24 Gy/fraction and 4.91 (P < .001) for 20 to 23 Gy/ fraction.

the hazard ratio was 3.53 (P = .0022) for osteolytic tumors. Paraspinal/epidural disease extension was a significant predictor on univariate but not multivariate analysis. The investigators concluded: Caution must be observed when treating with ≥ 20 Gy/fraction, in particular, for patients with lytic tumor, spinal misalignment, and a baseline vertebral compression fracture. Frequent shortterm follow-up is required, as nearly two-thirds of all vertebral compression fractures occurred within the first 4 months.

Future of Oncology Advancing Psychosocial Oncology Care Over the Next Decade A Conversation With Jimmie C. Holland, MD By Jo Cavallo

A

psychiatrist for more than 40 years, Jimmie C. Holland, MD, Attending Psychiatrist and Wayne E. Chapman Chair at Memorial SloanKettering Cancer Center and Professor of Psychiatry, Weill Medical College of Cornell University in New York, is internationally recognized as the founder of the subspecialty of psycho-oncology. Dr. Holland conducted some of the first studies on the psychological impact of a cancer diagnosis on patients and proved that interventions to combat the anxiety and depression associated with cancer can work. According to Dr. Holland’s research, one-third of patients with cancer experience clinically significant mental distress. To help oncologists evaluate their patients’ distress levels, Dr. Holland and her colleagues at the National Comprehensive Cancer Network developed a “distress thermometer,” a psychosocial distress-screening tool that measures a patient’s distress level on a 0-to-10 scale. If a patient scores 4 or higher on the distress thermometer, it is a signal that the individual should be further evaluated and referred to a mental health-care specialist and monitored closely. Based on the Institute of Medicine (IOM) report, Cancer Care for the Whole Patient: Meeting Psychosocial Health Needs, the Commission on Cancer, which accredits centers that treat patients with cancer, mandated that by 2015 providers must have a plan in place to evaluate patients for distress and refer them to programs for help. The ASCO Post talked with Dr. Holland about integrating psychosocial care into routine cancer care, the progress being made in implementing methods to identify distress levels in patients, and advancements predicted over the next decade in the field of psycho-oncology.

Treating the Whole Patient Please talk about the importance of caring for the whole patient and integrating psychosocial care into routine cancer care. Cancer has had a particularly frightening stigma attached to it because for centuries we didn’t know the

cause of it and we didn’t have a cure. The result was that people didn’t even say the word “cancer” because it was so frightening. Patients often were not even told of their diagnosis, and doctors gave up before they started treatment, because they thought there was nothing more to be done. Those things really had an impact

unless you have integrated the psychosocial aspect into routine medical care. That was enormously helpful, and we took the report findings to the International Psycho-Oncology Society and the International Union Against Cancer, and about 60 countries have now endorsed the IOM’s recommendations.

Our main issue is the implementation of a psychosocial program in every cancer center in the country by 2015.… Once that happens, it will change the patient experience enormously. —Jimmie C. Holland, MD

on people feeling that somehow cancer is different from heart disease or other life-threatening diseases. Cancer became more than just a disease, it was a metaphor for all bad things, so it had a fearsome meaning for a long while. It wasn’t until Elisabeth Kübler Ross, MD, came around in the late 1950s and said that people with cancer want to talk about their disease, even when they have advancing disease, and doctors and nurses should be encouraging that communication, not avoiding the subject. That led to a change in the humanistic side of medicine. But the idea of treating the whole patient, both the physical and psychological ramifications of cancer, didn’t happen until more recently. It has been an uphill battle to get across the idea that you must treat the whole person—that you must have a way to incorporate treatment of both the tumor and the emotional distress patients feel into your everyday care. What was the turning point? Things significantly changed in 2007, when the IOM report was published. The central message of the report was that there are evidence-based interventions—both psychological and pharmacologic—for patients with cancer, and that you cannot say you’re doing quality cancer care today

In 2012, the Commission on Cancer (COC) mandated that in order to receive accreditation, cancer centers across the country must have a program in place by 2015 to identify distressed patients and refer them to the proper source. Are you seeing evidence that cancer centers are starting to comply with the mandate? Many centers still don’t have a distress program in place, but I think they are all concerned about meeting the deadline. We are working very hard with various organizations to provide staff education and help them implement programs.

Looking Ahead What advancements do you see in psycho-oncology over the next 5 to 10 years, and how will those advancements benefit patients? I often say we’ve always had a carrot to get people to pay attention to the psychosocial needs of patients. Now for the first time, we also have a stick—the mandate from the COC. So I think that within 5, and certainly 10 years, every center will have some type of psychosocial program. The programs will vary from place to place, depending on the number of staff and resources they have, but at least some type of psychosocial

program will be available for patients with cancer in every cancer center, whereas often there is nothing along those lines now. Once the ball starts rolling, people will see how important this program is, how grateful patients are, and that it is a big value added. Over the next decade, there probably will be more ways to find out which patients meet the criteria for distress and need some type of therapy. For example, there might be a way patients can use their electronic health record to punch in whether they are feeling distressed, and we will be able to get help to more people in that way. We would love to see a better way to diagnose and treat patients suffering from all forms of distress, including depression, anxiety, and insomnia. Part of the COC mandate is that you must triage patients to a mental health resource for monitoring or treatment. But right now it’s hard to find mental health counselors in many parts of the country, and that’s a big area we need to work on—how to triage patients to a proper resource. We need to come up with a national plan so people can find psychological help that has been vetted and that includes mental health professionals who know about cancer and its impact on patients and can offer counseling. Currently, a wide array of evidence-based interventions are available to help patients cope with their level of distress, and that will grow wider. There are several forms of counseling, mindfulness meditation, yoga, relaxation techniques, music, and dance therapy, which qualify as complementary therapies. There are also medications for more serious types of distress. So the future looks good for providing patients with more helpful options. The other area that needs attention is the shortage of mental health experts trained in the problems of having cancer. We need more opportunities to encourage and train young people in the fields of psychology and social work and then train them in the issues that affect patients with cancer. We also need to be sure that there are psychiatrists consulting with all the cancer centers, so every center has access to somebody who knows how to

Future of Oncology prescribe psychiatric medication and can diagnose the more formal psychiatric disorders.

Survivorship Issues Will the need for psychosocial care for patients with cancer become even more important as the number of survivors grows? Yes. There are over 13 million cancer survivors in the country, but the psychological issues do not end once treatment is over. There is anxiety about the cancer coming back and

the long-term and late side effects of treatment. All of the survivorship issues are new. When I started out, for example, there were not many Hodgkin lymphoma survivors, and now, almost 100% of those patients are cured, so we have a big survivorship population. We’re learning more about the

psychosocial problems patients have, and it has opened a whole new era for us. That said, our main issue is the implementation of a psychosocial program in every cancer center in the country by 2015. That’s where we are right now. We are trying to see how we can help all these cancer centers

meet the new accreditation deadline. Once that happens, it will change the patient experience enormously, because oncologists will at least be paying attention to psychosocial issues in a way that hasn’t been true up to now. So things are changing. n

Circulating Estrogens and Androgens Associated With Breast Cancer Risk in Premenopausal Women By Matthew Stenger

I

n a study reported in The Lancet Oncology, Timothy Key, DPhil, of Oxford University, and colleagues in the Endogenous Hormones and Breast Cancer Collaborative Group analyzed data from seven prospective studies to determine associations between sex hormones and risk of breast cancer in premenopausal women.1 They found that estradiol, calculated free estradiol, estrone, androstenedione, dehydroepiandrosterone sulphate (DHEAS), and testosterone concentrations were positively associated with risk of breast cancer and that luteal phase progesterone and sex hormone– binding globulin were not.

stratification by study and further adjustment for cycle phase.

Estrogens and Androgens Associated With Risk The analyses included data for up to 767 women with breast cancer and 1,699 controls. Breast cancer risk was significantly associated with a doubling in concentrations of estradiol

This collaborative analysis noted a positive association between sex hormones and breast cancer risk in premenopausal women. Whether or not this association is causal is not known, but plausible biological mechanisms exist that could explain such an effect.

Study Details Individual participant data for prediagnostic sex hormone and sex hormone–binding globulin concentrations were contributed from seven prospective studies, with analyses restricted to women who were premenopausal and younger than 50 years at blood collection and to women with breast cancer diagnosed before age 50 years. Most of the women in the analysis were of white European ethnic origin. Odds ratios for breast cancer associated with hormone concentrations were calculated for cases and controls matched for age, date of blood collection, and day of cycle, with

testosterone (OR = 1.08, 95% CI = 0.97–1.21), luteal phase progesterone (OR = 1.00, 95% CI = 0.92–1.09), or sex hormone–binding globulin (OR = 1.07, 95% CI = 0.94–1.23). Further adjustment for age at menarche, age at first full-term pregnancy, number of full-term pregnancies, and body mass index had little effect on any of these odds ratios, except that the asso-

(OR = 1.19, 95% confidence interval [CI] = 1.06–1.35), calculated free estradiol (OR = 1.17, 95% CI = 1.03– 1.33), estrone (OR = 1.27, 95% CI = 1.05–1.54), androstenedione (OR = 1.30, 95% CI = 1.10–1.55), DHEAS (OR = 1.17, 95% CI = 1.04–1.32), and testosterone (OR = 1.18, 95% CI = 1.03–1.35), but not calculated free

ciation with doubling of calculated free testosterone with risk became significant (OR = 1.14, 95% CI = 1.01–1.28). There was no evidence suggesting that any of the odds ratios varied by the time between blood collection and diagnosis. For estrogens and androgens, the odds ratios were larger for estrogen receptor–positive tumors than for es-

trogen receptor-negative tumors (eg, 1.25 vs 1.09 for estradiol, 1.26 vs 0.90 for estrone, 1.45 vs 1.11 for androstenedione, and 1.13 vs 1.03 for testosterone), but none of the differences was significant (all P > .19 for heterogeneity). For estradiol according to phase of the menstrual cycle, the odds ratios for a doubling in concentration were 1.25 (95% CI = 1.06–1.48) for follicular samples, 1.20 (0.81–1.79) for midcycle samples, and 1.13 (0.92–1.37) for luteal samples (P = .732 for heterogeneity).

Association of Sex Hormones With Risk Factors in Controls Cross-sectional analyses in control women showed several associations of sex hormones with breast cancer risk factors. Compared with women with a body mass index of less than 22.5 kg/m2, those with a body mass index of 30 kg/m2 or more had lower mean concentrations of estradiol (by 17%), luteal phase progesterone (by 28%), and sex hormone–binding globulin (by 46%), and body mass index was positively associated with higher mean concentrations of calculated free estradiol (by 10%), estrone (by 16%), DHEAS (by 8%), testosterone (by 7%), and calculated free testosterone (by 63%), with means adjusted for age,

Evidence-Based Opportunity to Personalize Breast Cancer Risk: The Data Are Building By Victor G. Vogel, MD, MHS

T

he worldwide data from prospective studies of the relationship between levels of endogenous sex hormones and breast cancer risk in postmenopausal women show multiple and complex relationships.1 Nine prospective studies (different from those reported here) of women not taking exogenous sex hormones when their blood was collected to determine hormone levels showed that the risk for breast cancer increased significantly with increasing concentrations of all sex hormones examined: total estradiol, free estradiol, non–sex hormone binding globulin (SHBG)-bound estradiol, estrone, estrone sulfate, andro-

stenedione, dehydroepiandrosterone, dehydroepiandrosterone sulfate, and testosterone. The relative risks for women with increasing quintiles of all hormone concentrations, relative to the lowest quintile, ranged from a marginal increase in risk to more than doubling of risk, and high SHBG was associated with a decrease in breast cancer risk. Interestingly, estradiol levels are generally higher in North American women than Asian women, and urinary estrogens are higher in North American teenagers, who face higher lifetime risks for breast cancer.

Dr. Vogel is Director, Breast Medical Oncology/Research, Geisinger Health System, Danville, Pennsylvania.

Earlier Data Earlier studies among women at increased risk for osteoporotic frac-

tures who had traditional risk factors for breast cancer showed that the risk for breast cancer was more than three times greater among women with the highest concentrations of bioavailable estradiol compared with women with the lowest concentrations.2 In addition, investigators in the Women’s Health Initiative, a randomized study of hormone replacement therapy in postmenopausal women, measured total estradiol, bioavailable estradiol, estrone, and estrone sulfate in the study subjects prior to enrollment in the trial. Conjugated equine estrogens plus progestin increased all measured estrogens and SHGB after 1 year of use. The effect of combination hormonal therapy on breast cancer risk

was strongest in women whose pretreatment levels of total estradiol, bioavailable estradiol, and estrone were in the lowest quartiles. Women with lower pretreatment endogenous estrogen levels were at greater risk of breast cancer during combined hormonal therapy compared with those with higher levels.3

Complex Relationship The relationship of circulating hormone levels to the risk of breast cancer, and to the type of cancer that develops, is complex. In a case-cohort study within the Women’s Health Initiative Observational Study among postmenopausal women aged 50 to 79 years, investigators examined associations between endogenous tescontinued on page 98

study, and cycle phase. Concentrations of sex hormones were lower in older women than in younger women and sex hormone– binding globulin was higher in older women. Parity was inversely associated with calculated free testosterone, but was not associated with concentrations of the other sex hormones or sex hormone–binding globulin, and none of the hormones or sex hormone–binding globulin was associated with age at menarche or family history of breast cancer. Compared with never-smokers, current smokers of at least 15 cigarettes per day had increased concentrations of androstenedione (by 21%), DHEAS (by 12%), testosterone (by 12%), and calculated free testosterone (by 13%). Compared with women who did not consume alcohol, women with an alcohol intake of at least 20 g/d had increased concentrations of androstenedione (by 13%), DHEAS (by 16%), testosterone (by 23%), and calculated free testosterone (by 23%). Adjustment of the analyses by smoking for alcohol and of the analyses by alcohol for smoking had no marked effect on the results. Women who had used hormonal contraceptives had lower concentrations of estradiol (by 7%), estrone (by 7%), androstenedione (by 5%), and sex hormone–binding globulin (by

tosterone and estradiol levels and the risks of estrogen receptor (ER)-negative and ER-positive breast cancers. Serum levels of bioavailable testosterone and estradiol were assessed at the baseline visit in both invasive breast cancer cases and in control women. Compared with women in the lowest quartile of testosterone level, those in the other three quartiles had half the risk of ER-negative cancer, independent of other risk factors. Perhaps not surprisingly, estradiol level was not associated with ER-negative breast cancer. Thus, higher serum levels of bioavailable testosterone appear to be associated with lower risks of ER-negative breast cancer in postmenopausal women.4

women at the highest risk. Additional data were reported from the UK Collaborative Trial of Ovarian Cancer Screening, in which 200 postmenopausal women who developed ER-positive breast cancer 0.6 to 5 years after sample donation were identified and matched to 400 controls. Estrogen receptor alpha and estrogen receptor beta serum bioactivity were both significantly higher before diagnosis in cases compared with controls, while estrogens showed no difference. Women had a twofold increased breast cancer risk if ER alpha serum bioactivity was in the top quintile more than 2 years before diagnosis or

Mammographic Density Circulating hormones have potential physiologic and morphologic effects on breast parenchymal tissue that can be assessed mammographically. In nested case-control studies

A strategy that combines quantitative risk assessment, mammographic density, and measurement of circulating hormone levels is likely to identify those women most likely to benefit from breast cancer risk reduction strategies such as chemoprevention.

Women With Other Risk Factors Hormone levels may not be predictive in women who have other risk factors for breast cancer. Among women at increased risk for breast cancer in the National Surgical Adjuvant Breast and Bowel Project (NSABP) Breast Cancer Prevention Trial,5 the relative risk of breast cancer for women in the placebo group was not associated with sex hormone levels.6 In addition, the reduced risk of invasive breast cancer in tamoxifentreated women compared with placebo-treated women was not associated with sex hormone levels. Consistent with these observations, in the Multiple Outcomes of Raloxifene Evaluation (MORE) study of raloxifene (Evista) in older postmenopausal women at risk for osteoporotic fractures, the majority of women had very low levels of estradiol.7 This observation raises the question of a possible “threshold effect” (ie, low risk at very low estradiol levels and high risk at estradiol levels above a “threshold” value). Contrary to the data from the Breast Cancer Prevention Trial, in a prospective, nested case-control study within the Nurses’ Health Study, estrone sulfate was associated with breast cancer risk among women with either low (< 1.66%) or high (≥ 2.52%; 75th percentile) Gail model-predicted risk of breast cancer.8 It is likely that there is a plateau in circulating hormone concentrations in

the risk associated with a doubling of testosterone levels was increased by more than 30%. The associations in Japanese American women, who constituted 54% of the sample, were similar to or nonsignificantly stronger than in the overall group. These data provide evidence, therefore, that the association between sex hormones and breast cancer risk is generalizable to an ethnically diverse population.10

if estrone was in the top quintile less than 2 years before diagnosis. Androstenedione levels were significantly higher compared with controls and showed a strong association, with an almost threefold increased breast cancer risk independent of time to diagnosis.9

Multiethnic Cohort These effects do not appear to be unique to white women. The ongoing Multiethnic Cohort study includes Japanese American, White, Native Hawaiian, African American, and Latina women. Investigators conducted a nested case-control study to examine the association between sex hormones and breast cancer risk. Levels of estradiol (E2), estrone (E1), androstenedione, dehydroepiandrosterone (DHEA), and testosterone were quantified by appropriate methods. E1 sulfate, DHEA sulfate (DHEAS), and SHBG were quantified by direct immunoassays. The sex hormones were positively associated and SHBG was negatively associated with breast cancer risk. The odds ratio associated with a doubling of E2 levels was greater than 2, and

within the Nurses’ Health Study, investigators examined plasma levels of estradiol, free estradiol, testosterone, and free testosterone along with mammographic density assessed by computer-assisted analysis of the mammograms. Levels of circulating sex steroids and mammographic density were both statistically significantly and independently associated with breast cancer risk. Circulating levels of estradiol and testosterone were both associated with at least a doubling of breast cancer risk, before and after adjustment for mammographic density. These data suggest that both circulating sex steroid levels and mammographic density are independently associated with the risk of breast cancer in postmenopausal women.11

Further Considerations The data reported by Key and colleagues in the Endogenous Hormones and Breast Cancer Collaborative Group, reviewed in this issue of The ASCO Post, are unique in that they report a relationship of circulating sex hormones to the risk of breast cancer among premenopausal wom-

en similar to that reported in postmenopausal women, although the magnitude of the effect in premenopausal women is modest when compared to the effect in older women.12 Key et al appear to have accounted for the menstrual cycle variability that occurs in the plasma levels of the hormones, and they have made appropriate statistical adjustments to control for known breast cancer risk factors, lending credence to their results. Polymorphisms in the genes coding for enzymes that metabolize sex steroids may also alter the risk of breast cancer. Several other genetic polymorphisms may influence sex hormone concentrations, including CYP17, CYP19, and CYP1B1. Associations between these polymorphisms and serum concentrations of estrogens, androgens, and SHBG and urinary concentrations of 2- and 16 alpha-hydroxyestrone have been studied,13 but whether the circulating levels of hormones or their metabolism is more important is not known. Additional indirect evidence of the role of endogenous hormones in the etiology of breast cancer comes from the adjuvant therapy trials with aromatase inhibitors.14 These agents interrupt hormonal synthesis, cause a greater than 90% decrease in the levels of circulating estrogens in postmenopausal women, and have shown a greater than 50% reduction in primary contralateral breast cancers as a first event among women treated with anastrozole when compared with women receiving tamoxifen. Similarly, the rate of contralateral breast cancer is half as great among postmenopausal women receiving letrozole compared with women taking tamoxifen in two adjuvant treatment trials.15,16

Practical Applications How might we use these data in clinical settings to reduce the risk of breast cancer? In the MORE trial mentioned above, women with the highest estradiol levels (≥ 12 pmol/L) had a twofold increased risk for invasive breast cancer compared with women with lower levels of estradiol.7 In the placebo group, women with estradiol levels greater than 10 pmol/L had a nearly sevenfold higher rate of breast cancer than women with uncontinued on page 100

detectable estradiol levels.17 Women with estradiol levels greater than 10 pmol/L in the raloxifene group had a rate of breast cancer that was 76% lower than that of women with estra-

diol levels greater than 10 pmol/L in the placebo group. Importantly, raloxifene reduced breast cancer risk in both the low- and high-estrogen subgroups for all risk factors examined, but the reduction was greatest in those with the highest estradiol levels. In contrast, women with

undetectable estradiol levels had similar breast cancer risk whether or not they were treated with raloxifene. Older postmenopausal women whose testosterone levels were in the highest two quintiles had a fourfold increased risk of ER-positive breast cancer.18

In International Study, Patients Prefer Subcutaneous Over Intravenous Trastuzumab for Breast Cancer By Matthew Stenger

S

ubcutaneous trastuzumab (not available in the United States) has been shown to have noninferior efficacy and similar pharmacokinetic and safety profiles compared with in-

given at 600 mg/5 mL (including 10,000 U of recombinant human hyaluronidase, or rHuPH20) injected into the thigh over approximately 5 minutes.

A fixed dose of 600 mg trastuzumab administered [subcutaneously] every 3 weeks is a validated, well tolerated treatment option for HER2-positive breast cancer, and is the preferred treatment of patients. —Xavier Pivot, MD, and colleagues

travenous trastuzumab (Herceptin) in patients with early-stage HER2positive breast cancer. In the PrefHer trial reported in Lancet Oncology, Xavier Pivot, MD, of CHU Jean Minjoz in Besançon, and colleagues found that such patients preferred subcutaneous trastuzumab over intravenous administration.1

Study Details In this international, open-label, crossover study, 248 patients aged 18 years or older with HER2-positive, histologically confirmed primary invasive breast adenocarcinoma were randomized to receive four cycles of 600 mg fixed-dose subcutaneous adjuvant trastuzumab via a singleuse injection device every 3 weeks followed by four cycles of standard intravenous trastuzumab every 3 weeks (SC/IV group, n = 124) or the reverse sequence (IV/SC group, n = 124). Intravenous trastuzumab was administered as a loading dose of 8 mg/ kg in patients receiving trastuzumab de novo (approximately 90 minutes) and a 6-mg/kg maintenance dose (approximately 60 minutes) thereafter. Subcutaneous trastuzumab was

Patients had to have no evidence of residual, locally recurrent, or metastatic disease after completion of surgery and neoadjuvant or adjuvant chemotherapy, Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1, and baseline left-ventricular ejection fraction ≥ 55% before the first dose of trastuzumab. Radiotherapy and hormone therapy were permitted. Randomization was stratified by de novo vs non–de novo use of intravenous trastuzumab. The primary endpoint was the proportion of patients indicating an overall preference for subcutaneous or intravenous administration, as assessed by patient interviews conducted at baseline and after

completion of the crossover period. A total of 117 SC/IV patients and 119 IV/SC patients completed both interviews. At baseline, these SC/IV and IV/SC groups had a median age of 55 and 51 years, 81% of both had ECOG performance status of 0, 51% and 33% had T1 disease and 32% and 48% had T2 disease, 54% and 43% had node-negative disease, and 25% and 24% were de novo trastuzumab users. Furthermore, 100% of both had received chemotherapy, 62% and 60% had received radiotherapy, and 43% and 40% had received hormone therapy.

Clear Preference In total, 216 (91.5%) of 236 patients preferred subcutaneous trastuzumab (P < .0001), 16 (7%), preferred intravenous administration, and 4 (2%) had no preference. In the SC/IV group, 112 (96%) of 117 preferred subcutaneous administration and 5 (4%) preferred intravenous administration. In the IV/SC group, 104 (87%) of 119 preferred subcutaneous administration, 11 (9%) preferred intravenous administration, and 4 (3%) had no preference. Preference for subcutaneous administration was found in 54 (95%)

Subcutaneous vs Intravenous Trastuzumab ■■ In an international study, more than 90% of patients with early-stage HER2-positive breast cancer preferred adjuvant trastuzumab given subcutaneously vs intravenously. (Subcutaneous trastuzumab is not available in the United States.)

■■ Subcutaneous administration was preferred by 96% of those receiving

subcutaneous trastuzumab first and by 86% of those receiving intravenous trastuzumab first in the crossover study.

■■ Subcutaneous administration was associated with a higher frequency of mild or moderate injection site reactions.

New from The ASCO Post

of 57 patients in the de novo trastuzumab group and in 162 (90.5%) of 179 who had previously received intravenous trastuzumab. Overall preference for subcutaneous trastuzumab was “very strong” in 67% of patents, “fairly strong” in 19%, and “not very strong” in 5%. Overall preference for intravenous administration was “very strong” in 3%, “fairly strong” in 1%, and “not very strong” in 2%. Factors that significantly influenced preference were study group (odds ratio [OR] = 3.28, 95% confidence interval [CI] = 1.14–9.48) and venous access type (OR = 4.61, 95% CI = 1.48–14.37). Preference for subcutaneous administration was 95% among patients receiving intravenous trastuzumab by cannula (122/129 patients) and 87% among those with a venous access device (90/113 patients). Hypothetical preference for subcutaneous administration was 46% at the baseline interview and did not affect final preference. Among the 216 patients preferring subcutaneous administration, the main reasons cited were “time saving” (90%) and “less pain/discomfort” (41%). Subcutaneous administration was considered to be less painful than intravenous administration by 67% vs 14% of patients (with 19% reporting no difference), to cause less bother from bruising by 46% vs 14% (with 40% reporting no difference), and to cause less bother from irritation to the injection site by 36% vs 15% (with 50% reporting no difference).

INLYTA has been shown to inhibit receptor tyrosine kinases, including VEGFR-1, -2, and -3 in vitro and in preclinical models Preclinical activity does not necessarily correlate with clinical outcomes

Liver enzyme elevation has been observed during treatment with INLYTA. Monitor ALT, AST, and bilirubin before initiation of, and periodically throughout, treatment. For patients with moderate hepatic impairment, the starting dose should be decreased. INLYTA has not been studied in patients with severe hepatic impairment. Women of childbearing potential should be advised of potential hazard to the fetus and to avoid becoming pregnant while receiving INLYTA. Avoid strong CYP3A4/5 inhibitors. If unavoidable, reduce the dose. Grapefruit or grapefruit juice may also increase INLYTA plasma concentrations and should be avoided. Avoid strong CYP3A4/5 inducers and, if possible, avoid moderate CYP3A4/5 inducers.

Please see brief summary on the following page.

The most common (≥20%) adverse events (AEs) occurring in patients receiving INLYTA (all grades, vs sorafenib) were diarrhea, hypertension, fatigue, decreased appetite, nausea, dysphonia, hand-foot syndrome, weight decreased, vomiting, asthenia, and constipation. The most common (≥10%) grade 3/4 AEs occurring in patients receiving INLYTA (vs sorafenib) were hypertension, diarrhea, and fatigue. The most common (≥20%) lab abnormalities occurring in patients receiving INLYTA (all grades, vs sorafenib) included increased creatinine, decreased bicarbonate, hypocalcemia, decreased hemoglobin, decreased lymphocytes (absolute), increased ALP, hyperglycemia, increased lipase, increased amylase, increased ALT, and increased AST.


Data are from a multicenter, open-label phase 3 trial of 723 patients with metastatic renal cell carcinoma (mRCC) after failure of 1st-line therapy (sunitinib-, temsirolimus-, bevacizumab-, or cytokine-containing regimens). Patients were randomized to either INLYTA (5 mg twice daily) or sorafenib (400 mg twice daily) with dose adjustments allowed in both groups. INLYTA® (AXITINIB) TABLETS FOR ORAL ADMINISTRATION Initial U.S. Approval: 2012 Brief Summary of Prescribing Information INDICATIONS AND USAGE: INLYTA is indicated for the treatment of advanced renal cell carcinoma (RCC) after failure of one prior systemic therapy. DOSAGE AND ADMINISTRATION Recommended Dosing. The recommended starting oral dose of INLYTA is 5 mg twice daily. Administer INLYTA doses approximately 12 hours apart with or without food. INLYTA should be swallowed whole with a glass of water. If the patient vomits or misses a dose, an additional dose should not be taken. The next prescribed dose should be taken at the usual time. Dose Modification Guidelines. Dose increase or reduction is recommended based on individual safety and tolerability. Over the course of treatment, patients who tolerate INLYTA for at least two consecutive weeks with no adverse reactions >Grade 2 (according to the Common Toxicity Criteria for Adverse Events [CTCAE]), are normotensive, and are not receiving anti-hypertension medication, may have their dose increased. When a dose increase from 5 mg twice daily is recommended, the INLYTA dose may be increased to 7 mg twice daily, and further to 10 mg twice daily using the same criteria. Over the course of treatment, management of some adverse drug reactions may require temporary interruption or permanent discontinuation and/or dose reduction of INLYTA therapy [see Warnings and Precautions]. If dose reduction from 5 mg twice daily is required, the recommended dose is 3 mg twice daily. If additional dose reduction is required, the recommended dose is 2 mg twice daily. Strong CYP3A4/5 Inhibitors: The concomitant use of strong CYP3A4/5 inhibitors should be avoided (e.g., ketoconazole, itraconazole, clarithromycin, atazanavir, indinavir, nefazodone, nelfinavir, ritonavir, saquinavir, telithromycin, and voriconazole). Selection of an alternate concomitant medication with no or minimal CYP3A4/5 inhibition potential is recommended. Although INLYTA dose adjustment has not been studied in patients receiving strong CYP3A4/5 inhibitors, if a strong CYP3A4/5 inhibitor must be co-administered, a dose decrease of INLYTA by approximately half is recommended, as this dose reduction is predicted to adjust the axitinib area under the plasma concentration vs time curve (AUC) to the range observed without inhibitors. The subsequent doses can be increased or decreased based on individual safety and tolerability. If co-administration of the strong inhibitor is discontinued, the INLYTA dose should be returned (after 3–5 half-lives of the inhibitor) to that used prior to initiation of the strong CYP3A4/5 inhibitor. Hepatic Impairment: No starting dose adjustment is required when administering INLYTA to patients with mild hepatic impairment (Child-Pugh class A). Based on the pharmacokinetic data, the INLYTA starting dose should be reduced by approximately half in patients with baseline moderate hepatic impairment (Child-Pugh class B). The subsequent doses can be increased or decreased based on individual safety and tolerability. INLYTA has not been studied in patients with severe hepatic impairment (Child-Pugh class C). DOSAGE FORMS AND STRENGTHS 1 mg tablets of INLYTA: red, film-coated, oval tablets, debossed with “Pfizer” on one side and “1 XNB” on the other side. 5 mg tablets of INLYTA: red, film-coated, triangular tablets, debossed with “Pfizer” on one side and “5 XNB” on the other side. CONTRAINDICATIONS: None WARNINGS AND PRECAUTIONS Hypertension and Hypertensive Crisis. In a controlled clinical study with INLYTA for the treatment of patients with RCC, hypertension was reported in 145/359 patients (40%) receiving INLYTA and 103/355 patients (29%) receiving sorafenib. Grade 3/4 hypertension was observed in 56/359 patients (16%) receiving INLYTA and 39/355 patients (11%) receiving sorafenib. Hypertensive crisis was reported in 2/359 patients (<1%) receiving INLYTA and none of the patients receiving sorafenib. The median onset time for hypertension (systolic blood pressure >150 mmHg or diastolic blood pressure >100 mmHg) was within the first month of the start of INLYTA treatment and blood pressure increases have been observed as early as 4 days after starting INLYTA. Hypertension was managed with standard antihypertensive therapy. Discontinuation of INLYTA treatment due to hypertension occurred in 1/359 patients (<1%) receiving INLYTA and none of the patients receiving sorafenib. Blood pressure should be well-controlled prior to initiating INLYTA. Patients should be monitored for hypertension and treated as needed with standard anti-hypertensive therapy. In the case of persistent hypertension despite use of anti-hypertensive medications, reduce the INLYTA dose. Discontinue INLYTA if hypertension is severe and persistent despite anti-hypertensive therapy and dose reduction of INLYTA, and discontinuation should be considered if there is evidence of hypertensive crisis. If INLYTA is interrupted, patients receiving antihypertensive medications should be monitored for hypotension. Arterial Thromboembolic Events. In clinical trials, arterial thromboembolic events have been reported, including deaths. In a controlled clinical study with INLYTA for the treatment of patients with RCC, Grade 3/4 arterial thromboembolic events were reported in 4/359 patients (1%) receiving INLYTA and 4/355 patients (1%) receiving sorafenib. Fatal cerebrovascular accident was reported in 1/359 patients (<1%) receiving INLYTA and none of the patients receiving sorafenib. In clinical trials with INLYTA, arterial thromboembolic events (including transient ischemic attack, cerebrovascular accident, myocardial infarction, and retinal artery occlusion) were reported in 17/715 patients (2%), with two deaths secondary to cerebrovascular accident [see Adverse Reactions]. Use INLYTA with caution in patients who are at risk for, or who have a history of, these events. INLYTA has not been studied in patients who had an arterial thromboembolic event within the previous 12 months. Venous Thromboembolic Events. In clinical trials, venous thromboembolic events have been reported, including deaths. In a controlled clinical study with INLYTA for the treatment of patients with RCC, venous thromboembolic events were reported in 11/359 patients (3%) receiving INLYTA and 2/355 patients (1%) receiving sorafenib. Grade 3/4 venous thromboembolic events were reported in 9/359 patients (3%) receiving INLYTA (including pulmonary embolism, deep vein thrombosis, retinal vein occlusion and retinal vein thrombosis) and 2/355 patients (1%) receiving sorafenib. Fatal pulmonary embolism was reported in 1/359 patients (<1%) receiving INLYTA and none of the patients receiving sorafenib. In clinical trials with INLYTA, venous thromboembolic events were reported in 22/715 patients (3%), with two deaths secondary to pulmonary embolism. Use INLYTA with caution in patients who are at risk for, or who have a history of, these events. INLYTA has not been studied in patients who had a venous thromboembolic event within the previous 6 months. Hemorrhage. In a controlled clinical study with INLYTA for the treatment of patients with RCC, hemorrhagic events were reported in 58/359 patients (16%) receiving INLYTA and 64/355 patients (18%) receiving sorafenib. Grade 3/4 hemorrhagic events were reported in 5/359 (1%) patients receiving INLYTA (including cerebral hemorrhage, hematuria, hemoptysis, lower gastrointestinal hemorrhage, and melena) and 11/355 (3%) patients receiving sorafenib. Fatal hemorrhage was reported in 1/359 patients (<1%) receiving INLYTA (gastric hemorrhage) and 3/355 patients (1%) receiving sorafenib. INLYTA has not been studied in patients who have evidence of untreated brain metastasis or recent active gastrointestinal bleeding and should not be used in those patients. If any bleeding requires medical intervention, temporarily interrupt the INLYTA dose. Gastrointestinal Perforation and Fistula Formation. In a controlled clinical study with INLYTA for the treatment of patients with RCC, gastrointestinal perforation was reported in 1/359 patients (<1%) receiving INLYTA and none of the patients receiving sorafenib. In clinical trials with INLYTA, gastrointestinal perforation was reported in 5/715 patients (1%), including one death. In addition to cases of gastrointestinal perforation, fistulas were reported in 4/715 patients (1%). Monitor for symptoms of gastrointestinal perforation or fistula periodically throughout treatment with INLYTA. Thyroid Dysfunction. In a controlled clinical study with INLYTA for the treatment of patients with RCC, hypothyroidism was reported in 69/359 patients (19%) receiving INLYTA and 29/355 patients (8%) receiving sorafenib. Hyperthyroidism was reported in 4/359 patients (1%) receiving INLYTA and 4/355 patients (1%) receiving sorafenib. In patients who had thyroid stimulating hormone (TSH) <5 μU/mL before treatment, elevations of TSH to *10 U/mL occurred in 79/245 patients (32%) receiving INLYTA and 25/232 patients (11%) receiving sorafenib. Monitor thyroid function before initiation of, and periodically throughout, treatment with INLYTA. Treat hypothyroidism and hyperthyroidism according to standard medical practice to maintain euthyroid state. Wound Healing Complications. No formal studies of the effect of INLYTA on wound healing have been conducted. Stop treatment with INLYTA at least 24 hours prior to scheduled surgery. The decision to resume INLYTA therapy after surgery should be based on clinical judgment of adequate wound healing. Reversible Posterior Leukoencephalopathy Syndrome. In a controlled clinical study with INLYTA for the treatment of patients with RCC, reversible posterior leukoencephalopathy syndrome (RPLS) was reported in 1/359 patients (<1%) receiving INLYTA and none of the patients receiving sorafenib. There were two additional reports of RPLS in other clinical trials with INLYTA. RPLS is a neurological disorder which can present with headache, seizure, lethargy, confusion, blindness and other visual and neurologic disturbances. Mild to severe hypertension may be present. Magnetic resonance imaging is necessary to confirm the diagnosis of RPLS. Discontinue INLYTA in patients developing RPLS. The safety of reinitiating INLYTA therapy in patients previously experiencing RPLS is not known. Proteinuria. In a controlled clinical study with INLYTA for the treatment of patients with RCC, proteinuria was reported in 39/359 patients (11%) receiving INLYTA and 26/355 patients (7%) receiving sorafenib. Grade 3 proteinuria was reported in 11/359 patients (3%) receiving INLYTA and 6/355 patients (2%) receiving sorafenib. Monitoring for proteinuria before initiation of, and periodically throughout, treatment with INLYTA is recommended. For patients who develop moderate to severe proteinuria, reduce the dose or temporarily interrupt INLYTA treatment.

AXU470817

Elevation of Liver Enzymes. In a controlled clinical study with INLYTA for the treatment of patients with RCC, alanine aminotransferase (ALT) elevations of all grades occurred in 22% of patients on both arms, with Grade 3/4 events in <1% of patients on the INLYTA arm and 2% of patients on the sorafenib arm. Monitor ALT, aspartate aminotransferase (AST) and bilirubin before initiation of and periodically throughout treatment with INLYTA. Hepatic Impairment. The systemic exposure to axitinib was higher in subjects with moderate hepatic impairment (Child-Pugh class B) compared to subjects with normal hepatic function. A dose decrease is recommended when administering INLYTA to patients with moderate hepatic impairment (Child-Pugh class B). INLYTA has not been studied in patients with severe hepatic impairment (Child-Pugh class C). Pregnancy. INLYTA can cause fetal harm when administered to a pregnant woman based on its mechanism of action. There are no adequate and well-controlled studies in pregnant women using INLYTA. In developmental toxicity studies in mice, axitinib was teratogenic, embryotoxic and fetotoxic at maternal exposures that were lower than human exposures at the recommended clinical dose. Women of childbearing potential should be advised to avoid becoming pregnant while receiving INLYTA. If this drug is used during pregnancy, or if a patient becomes pregnant while receiving this drug, the patient should be apprised of the potential hazard to the fetus. ADVERSE REACTIONS Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice. The safety of INLYTA has been evaluated in 715 patients in monotherapy studies, which included 537 patients with advanced RCC. The data described reflect exposure to INLYTA in 359 patients with advanced RCC who participated in a randomized clinical study versus sorafenib. The following risks, including appropriate action to be taken, are discussed in greater detail in other sections of the label: hypertension, arterial thromboembolic events, venous thromboembolic events, hemorrhage, gastrointestinal perforation and fistula formation, thyroid dysfunction, wound healing complications, RPLS, proteinuria, elevation of liver enzymes, and fetal development. Clinical Trials Experience. The median duration of treatment was 6.4 months (range 0.03 to 22.0) for patients who received INLYTA and 5.0 months (range 0.03 to 20.1) for patients who received sorafenib. Dose modifications or temporary delay of treatment due to an adverse reaction occurred in 199/359 patients (55%) receiving INLYTA and 220/355 patients (62%) receiving sorafenib. Permanent discontinuation due to an adverse reaction occurred in 34/359 patients (9%) receiving INLYTA and 46/355 patients (13%) receiving sorafenib. The most common (*20%) adverse reactions observed following treatment with INLYTA were diarrhea, hypertension, fatigue, decreased appetite, nausea, dysphonia, palmar-plantar erythrodysesthesia (hand-foot) syndrome, weight decreased, vomiting, asthenia, and constipation.

DRUG INTERACTIONS In vitro data indicate that axitinib is metabolized primarily by CYP3A4/5 and, to a lesser extent, CYP1A2, CYP2C19, and uridine diphosphate-glucuronosyltransferase (UGT) 1A1. CYP3A4/5 Inhibitors. Co-administration of ketoconazole, a strong inhibitor of CYP3A4/5, increased the plasma exposure of axitinib in healthy volunteers. Co-administration of INLYTA with strong CYP3A4/5 inhibitors should be avoided. Grapefruit or grapefruit juice may also increase axitinib plasma concentrations and should be avoided. Selection of concomitant medication with no or minimal CYP3A4/5 inhibition potential is recommended. If a strong CYP3A4/5 inhibitor must be coadministered, the INLYTA dose should be reduced [see Dosage and Administration]. CYP3A4/5 Inducers. Co-administration of rifampin, a strong inducer of CYP3A4/5, reduced the plasma exposure of axitinib in healthy volunteers. Co-administration of INLYTA with strong CYP3A4/5 inducers (e.g., rifampin, dexamethasone, phenytoin, carbamazepine, rifabutin, rifapentin, phenobarbital, and St. John’s wort) should be avoided. Selection of concomitant medication with no or minimal CYP3A4/5 induction potential is recommended [see Dosage and Administration]. Moderate CYP3A4/5 inducers (e.g., bosentan, efavirenz, etravirine, modafinil, and nafcillin) may also reduce the plasma exposure of axitinib and should be avoided if possible. USE IN SPECIFIC POPULATIONS Pregnancy. Pregnancy Category D [see Warnings and Precautions]. There are no adequate and well-controlled studies with INLYTA in pregnant women. INLYTA can cause fetal harm when administered to a pregnant woman based on its mechanism of action. Axitinib was teratogenic, embryotoxic and fetotoxic in mice at exposures lower than human exposures at the recommended starting dose. If this drug is used during pregnancy, or if the patient becomes pregnant while receiving this drug, the patient should be apprised of the potential hazard to the fetus. Oral axitinib administered twice daily to female mice prior to mating and through the first week of pregnancy caused an increase in post-implantation loss at all doses tested (*15 mg/kg/dose, approximately 10 times the systemic exposure (AUC) in patients at the recommended starting dose). In an embryo-fetal developmental toxicity study, pregnant mice received oral doses of 0.15, 0.5 and 1.5 mg/kg/dose axitinib twice daily during the period of organogenesis. Embryo-fetal toxicities observed in the absence of maternal toxicity included malformation (cleft palate) at 1.5 mg/kg/dose (approximately 0.5 times the AUC in patients at the recommended starting dose) and variation in skeletal ossification at *0.5 mg/kg/dose (approximately 0.15 times the AUC in patients at the recommended starting dose). Nursing Mothers. It is not known whether axitinib is excreted in human milk. Because many drugs are excreted in human milk and because of the potential for serious adverse reactions in nursing infants from INLYTA, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother. Pediatric Use. The safety and efficacy of INLYTA in pediatric patients have not been studied. Toxicities in bone and teeth were observed in immature mice and dogs administered oral axitinib twice daily for 1 month or longer. Effects in bone consisted of thickened growth plates in mice and dogs at *15 mg/kg/dose (approximately 6 and 15 times, respectively, the systemic exposure (AUC) in patients at the recommended starting dose). Abnormalities in growing incisor teeth (including dental caries, malocclusions and broken and/or missing teeth) were observed in mice administered oral axitinib twice daily at *5 mg/kg/dose (approximately 1.5 times the AUC in patients at the recommended starting dose). Other toxicities of potential concern to pediatric patients have not been evaluated in juvenile animals. Geriatric Use. In a controlled clinical study with INLYTA for the treatment of patients with RCC, 123/359 patients (34%) treated with INLYTA were *65 years of age. Although greater sensitivity in some older individuals cannot be ruled out, no overall differences were observed in the safety and effectiveness of INLYTA between patients who were *65 years of age and younger. No dosage adjustment is required in elderly patients. Hepatic Impairment. In a dedicated hepatic impairment trial, compared to subjects with normal hepatic function, systemic exposure following a single dose of INLYTA was similar in subjects with baseline mild hepatic impairment (Child-Pugh class A) and higher in subjects with baseline moderate hepatic impairment (Child-Pugh class B). No starting dose adjustment is required when administering INLYTA to patients with mild hepatic impairment (Child-Pugh class A). A starting dose decrease is recommended when administering INLYTA to patients with moderate hepatic impairment (Child-Pugh class B). INLYTA has not been studied in subjects with severe hepatic impairment (Child-Pugh class C). Renal Impairment. No dedicated renal impairment trial for axitinib has been conducted. Based on the population pharmacokinetic analyses, no significant difference in axitinib clearance was observed in patients with pre-existing mild to severe renal impairment (15 mL/min )creatinine clearance [CLcr] <89 mL/min). No starting dose adjustment is needed for patients with pre-existing mild to severe renal impairment. Caution should be used in patients with end-stage renal disease (CLcr <15 mL/min). OVERDOSAGE There is no specific treatment for INLYTA overdose. In a controlled clinical study with INLYTA for the treatment of patients with RCC, 1 patient inadvertently received a dose of 20 mg twice daily for 4 days and experienced dizziness (Grade 1). In a clinical dose finding study with INLYTA, subjects who received starting doses of 10 mg twice daily or 20 mg twice daily experienced adverse reactions which included hypertension, seizures associated with hypertension, and fatal hemoptysis. In cases of suspected overdose, INLYTA should be withheld and supportive care instituted. NONCLINICAL TOXICOLOGY Carcinogenesis, Mutagenesis, Impairment of Fertility. Carcinogenicity studies have not been conducted with axitinib. Axitinib was not mutagenic in an in vitro bacterial reverse mutation (Ames) assay and was not clastogenic in the in vitro human lymphocyte chromosome aberration assay. Axitinib was genotoxic in the in vivo mouse bone marrow micronucleus assay. INLYTA has the potential to impair reproductive function and fertility in humans. In repeat-dose toxicology studies, findings in the male reproductive tract were observed in the testes/epididymis (decreased organ weight, atrophy or degeneration, decreased numbers of germinal cells, hypospermia or abnormal sperm forms, reduced sperm density and count) at *15 mg/kg/dose administered orally twice daily in mice (approximately 7 times the systemic exposure (AUC) in patients at the recommended starting dose) and *1.5 mg/kg/dose administered orally twice daily in dogs (approximately 0.1 times the AUC in patients at the recommended starting dose). Findings in the female reproductive tract in mice and dogs included signs of delayed sexual maturity, reduced or absent corpora lutea, decreased uterine weights and uterine atrophy at *5 mg/kg/dose (approximately 1.5 or 0.3 times the AUC in patients at the recommended starting dose compared to mice and dogs, respectively). In a fertility study in mice, axitinib did not affect mating or fertility rate when administered orally twice daily to males at any dose tested up to 50 mg/kg/dose following at least 70 days of administration (approximately 57 times the AUC in patients at the recommended starting dose). In female mice, reduced fertility and embryonic viability were observed at all doses tested (*15 mg/kg/dose administered orally twice daily) following at least 15 days of treatment with axitinib (approximately 10 times the AUC in patients at the recommended starting dose). PATIENT COUNSELING INFORMATION Reversible Posterior Leukoencephalopathy Syndrome. Advise patients to inform their doctor if they have worsening of neurological function consistent with RPLS (headache, seizure, lethargy, confusion, blindness and other visual and neurologic disturbances). Pregnancy. Advise patients that INLYTA may cause birth defects or fetal loss and that they should not become pregnant during treatment with INLYTA. Both male and female patients should be counseled to use effective birth control during treatment with INLYTA. Female patients should also be advised against breast-feeding while receiving INLYTA. Concomitant Medications. Advise patients to inform their doctor of all concomitant medications, vitamins, or dietary and herbal supplements. Rx only Issued: February 2012 Reference: 1.

nel queried on preference, 74% vs 2% were more satisfied with subcutaneous administration, with 24% expressing no preference.

Adverse Events Clinician-reported adverse events occurred in 141 (58%) of 242 patients during the pooled subcutaneous periods, including grade 1 events in 51%, grade 2 in 22%, and grade 3 in 3%, and in 105 (44%) of 241 during the pooled intravenous periods, including grade 1 events in 32%, grade 2 in 19%, and grade 3 in 2%. The most common grade 3 adverse event was influenza, which occurred in two patients (0.8%). The most common adverse events during subcutaneous administration periods were injection site reactions (19% vs 0% during intravenous periods) and administration-related reactions (9% vs 5%). The most common adverse event during intravenous periods was arthralgia (6% vs 4%). Study drug discontinuation due to adverse events occurred in two patients (0.8%) during subcu-

taneous periods and one patient (0.4%) during intravenous periods. Data collection for Pref Her is ongoing, including data from a cohort using a handheld syringe for subcutaneous administration. A prospective, international, openlabel, nonrandomized study (SafeHer study, NCT01566721) is assessing the safety and tolerability of adjuvant subcutaneous trastuzumab via handheld syringe injection and assisted or self-administered singleuse injection device, with or without chemotherapy, in 2,500 patients with HER2-positive early breast cancer. The study will have a followup period of 5 years to permit longterm safety assessment. The investigators concluded, “Patient preference and safety results from Pref Her, combined with the known non-inferior efficacy and pharmacokinetic and safety profile data, suggest that a fixed dose of 600 mg trastuzumab administered [subcutaneously] every 3 weeks is a validated, well tolerated treatment option for HER2-positive breast cancer, and is the preferred treatment of patients.” n

EXPERT POINT OF VIEW By Edith A. Perez, MD

T

he Pref Her trial provides notable data showing that > 90% of patients favored the quicker subcutaneous administration of trastuzumab (Herceptin) compared to the standard intravenous infusion. The primary reasons for this preference, as per patients in the trial, included that it was timesaving and was associated with less pain/discomfort. Interestingly, there was an overwhelming preference for the subcutaneous administration among the health-care workers, too. Edith A. Perez, MD These data reflect the value of safe and timeeffective strategies to administer anticancer therapies to our patients. We want our patients to derive significant benefits from therapy, while being allowed to have the least possible disruptions to their lives. This new formulation appears to meet the criteria to be considered an improvement in the therapeutic armamentarium for patients. n Disclosure: Dr. Perez has received research funding from Genentech and GlaxoSmithKline.

No Progression-Free Survival Difference for Cediranib or Cediranib/Lomustine vs Lomustine in Recurrent Glioblastoma By Matthew Stenger

I

n a phase III study (REGAL trial) reported in the Journal of Clinical Oncology, Tracy T. Batchelor, MD, MPH, of the Massachusetts General Hospital Cancer Center, and colleagues compared oral monotherapy with the investigational pan–vascular endothelial growth factor (VEGF) receptor tyrosine kinase inhibitor cediranib and the combination of cediranib plus lomustine (CeeNu) vs a control arm of lomustine alone in patients with recurrent glioblastoma.1 There was no significant difference in progression-free or overall survival for either cediranib alone or cediranib/lomustine compared with lomustine alone.

Study Details In the trial, 325 patients aged 18 years or older with recurrent glioblastoma in whom prior radiation therapy and temozolomide had failed were randomly assigned in a 2:2:1 scheme to cediranib at 30 mg/d (n = 131), cediranib at 20 mg/d plus lomustine at 110 mg/m2 once every 6 weeks (n = 129), or lomustine plus placebo (n = 65). Enrollment was contingent on patients not having received prior anti-VEGF therapy. Other eligibility criteria included Karnofsky performance status ≥ 70, Mini-Mental Status Examination score ≥ 15, and life expectancy ≥12 weeks. The cediranib, cediranib/lomustine, and lomustine groups were well matched for age (median, 54 years in all groups) and resection for recurrent disease (38%, 38%, and 37%), but fewer patients in the lomustine group had Karnofsky performance status of 80 or less (ie, Karnofsky performance status = 90–100 in 50%, 51%, and 62.5%) or used corticosteroids at baseline (49%, 55%, and 40%). The primary endpoint was progression-free survival, based on centralized, blinded, independent radiographic assessment of postcontrast T1-weighted and noncontrast T2weighted MRI brain scans.

Progression-Free Survival Outcomes There was no significant difference in progression-free survival for the cediranib group (hazard ratio [HR] = 1.05, P = .90) or the combination

therapy group (HR = 0.76, P = .16) vs the lomustine group. Median progression-free survival was 92 days (1st quartile, 80 days; 3rd quartile, 128 days) in the cediranib group, 125 days (1st quartile, 83 days; 3rd quartile, 201 days) in the combination group, and 82 days (1st quartile, 42 days; 3rd quartile, 168 days) in the lomustine group. There were no significant progression-free survival differences between the cediranib group and the combination group vs the lomustine group on either central review of postcontrast T1-weighted or noncontrast T2/fluid-attenuated inversion recovery MRI scans or local review of postcontrast T1weighted MRI scans. Proportions of patients alive and progression-free at 6 months after randomization were 16% in the cediranib group, 35% in the combination group, and 25% in the lomustine group. A total of 136 patients received postprogression therapy. The majority received bevacizumab (Avastin) alone or in combination, including 51% of combination patients, 51% of lomustine patients, and 27% of cediranib patients.

Secondary Efficacy Measures There were no differences in median overall survival between the cediranib group (8.0 months, HR = 1.43, P = .10) or the combination group (9.4 months, HR = 1.15, P = .50) vs the lomustine group (9.8 months). Predictive power calculations indicated that there was < 0.01% chance of concluding a positive outcome at the final overall survival analysis, and it was thus considered of no value to continue to final analysis. There were no differences in the radiographic response rates between the two cediranib-containing groups. Best overall response rates were 15.3%

in the cediranib group (including one complete response), 17.2% in the combination group (including two compete responses), and 8.9% in the lomustine group. Median changes in contrast-enhanced tumor area were –36% in the cediranib group, –28% in the combination group, and +14% in the lomustine group. Clinical activity of cediranib was suggested by greater reduction in mean corticosteroid use in the cediranib group (–26%) and combination group (–23%) compared with the lomustine group (+5%; P = .01 for each vs lomustine) and by increased

38%, and 22%) and neutropenia (1%, 20%, and 3%). Other grade 3 or 4 adverse events occurring in at least 10% of any treatment group included fatigue (16%, 15%, and 9%), hypertension (14%, 6.5%, and 0%), and leukopenia (0.8%, 11%, and 5%). Serious adverse events occurred in 43%, 37%, and 41% of patients, respectively, and adverse events led to discontinuation of cediranib or placebo in 15%, 18%, and 16% of patients, respectively.

This study did not meet its primary end point of [progression-free survival] prolongation with cediranib either as monotherapy or in combination with lomustine versus lomustine in patients with recurrent glioblastoma. —Tracy T. Batchelor, MD, MPH, and colleagues

time to deterioration in neurologic status in the cediranib group (HR = 0.82, P = .57) and the combination group (HR = 0.63, P = .01). There were no differences in time to deterioration of Karnofsky performance status for the cediranib group (HR = 1.03, 95% confidence interval [CI] = 0.65–1.62) or the combination group (HR = 0.73, 95% CI = 0.45–1.17) vs the lomustine group.

Toxicity The most common adverse event was diarrhea (71% in cediranib group, 71% in combination group, and 19% in lomustine group). Adverse events of grade 3 or higher were more common in the combination group (61%, 80%, and 61%), including thrombocytopenia (2%,

Role of Cediranib in Glioblastoma ■■ No difference in progression-free survival was observed for cediranib

(30 mg) or cediranib (20 mg) plus lomustine vs lomustine alone in patients with recurrent glioblastoma.

■■ Clinical activity of cediranib was suggested by reduced use of

corticosteroids and increased time to neurologic deterioration in the cediranib and combination groups.

The investigators concluded, “This study did not meet its primary end point of [progression-free survival] prolongation with cediranib either as monotherapy or in combination with lomustine versus lomustine in patients with recurrent glioblastoma, although cediranib showed evidence of clinical activity on some secondary end points including time to deterioration in neurologic status and corticosteroid-sparing effects.” They noted that since preclinical models suggest synergistic activity of anti-VEGF therapy and radiation therapy, cediranib in combination with chemoradiotherapy is being studied in phase II trials in patients with newly diagnosed glioblastoma (NCT00662506 and NCT01062425). n

Fatty Acid Network Exerts Growth Inhibitory Effects in Pancreatic Cancer In a study reported in Clinical Cancontinued on page 108

The role of tumor-infiltrating lymphocytes in glioblastoma has not been fully defined. In a study reported in Clinical Cancer Research, Rutledge and colleagues assessed the association between tumorinfiltrating lymphocytes and molecular alterations, histologies, and survival in glioblastoma. In the study, histopathologic images from 171 glioblastomas from The Cancer Genome Atlas were used to categorize tumorinfiltrating lymphocytes as absent, present, or abundant, and associations were examined between lymphocytes and histologic features, mutations, copy number alterations, CpG island methylator phenotype, transcriptional class, and survival. Histologic findings were validated using CD3G gene expression.

Strong Associations A positive correlation was found between tumor-infiltrating lymphocytes and glioblastomas with gemistocytes, sarcomatous cells, epithelioid cells, and giant cells. Lymphocytes were enriched in the mesenchymal transcriptional class and strongly associated with mutations in NF1 and RB1, mutations that are frequent in the mesenchymal class and characteristic of gemistocytic, sarcomatous, epithelioid, and giant cell histologies. Tumor-infiltrating lymphocytes were rare in glioblastomas with small cells and oligodendroglioma components and were depleted in the classical transcriptional class and in EGFR-amplified and homozygous PTEN-deleted glioblastomas. These alterations are, in turn, characteristic of glioblastomas with small cells and glioblastomas of the classical transcriptional class. No association of tumor-infiltrating lymphocytes with survival was observed. The investigators concluded, “[Tumor-infiltrating lymphocytes] were enriched in glioblastomas of the mesenchymal class, strongly as-

cer Research, Zhang and colleagues used integrated metabolomics and transcriptomics to investigate genemetabolic networks and identify metabolic pathways that are perturbed in

pancreatic ductal adenocarcinoma. A global metabolite profiling analysis was performed on two independent cohorts of resected pancreatic ductal adenocarcinoma cases to identify critical metabolite alterations that may contribute to the progression of cancer. Gene surrogates significantly cor-

related with the key metabolites were identified by integrating metabolite and gene-expression profiles. A total of 55 metabolites were consistently altered in tumors compared with adjacent nontumor tissues in a test cohort (n = 33) and an independent validation cohort (n = 31). Weighted

network analysis identified a unique set of free fatty acids that were highly coregulated and decreased in pancreatic cancer Pathway analysis of 157 differentially expressed gene surrogates showed a significantly altered lipid metabolism network, including the key lipolytic en-

zymes PNLIP, CLPS, PNLIPRP1, and PNLIPRP2. Gene expressions of these lipases were significantly decreased in pancreatic tumors as compared with nontumor tissues, leading to reduced levels of free fatty acids. Lower gene expression of PNLIP in tumors was associated with poorer sur-

vival in two independent cohorts. It was further shown that two saturated free fatty acids, palmitate and stearate, significantly induced TRAIL expression, triggered apoptosis, and inhibited proliferation in pancreatic cancer cells. The investigators concluded, “Our results suggest that impairment in a li-

polytic pathway involving lipases, and a unique set of [free fatty acids], may play an important role in the development and progression of pancreatic cancer and provide potential targets for therapeutic intervention.” Zhang G, et al: Clin Cancer Res 19:4983-4993, 2013.

It has been found that focal adhesion kinase (FAK) inhibition sensitizes ovarian cancer to the effects of taxanes. In a study reported in the Journal of the National Can-

cer Institute, Kang and colleagues evaluated the response of taxaneresistant and taxane-sensitive ovarian cancer models to a novel FAK inhibitor (VS-6063). Reverse-phase protein arrays were used to identify novel downstream targets in taxaneresistant cell lines, and clinical and

pathologic data were correlated with nuclear and cytoplasmic expression of FAK and YB-1, a mediator of taxane resistance present at high levels in taxane-resistant cells, in 105 ovarian cancer samples. It was found that the FAK inhibitor blocked FAK phosphorylation at

the Tyr397 site in a time- and dosedependent manner. The combination of FAK inhibitor and paclitaxel reduced proliferation and increased apoptosis, resulting in 92.7% to 97.9% reductions in tumor weight. Reverse-phase protein array data showed that the FAK inhibitor reduced levels of AKT and YB-1 in taxane-resistant cell lines. FAK inhibition enhanced chemosensitivity in taxane-resistant cells by decreasing YB-1 phosphorylation and subsequently CD44 in an AKT-dependent manner. In human ovarian cancer samples, nuclear FAK expression was associated with increased nuclear YB-1 expression, and coexpression of nuclear FAK and YB-1 was associated with significantly worse median overall survival (24.9 vs 67.3 months, hazard ratio = 2.64, P = .006). The investigators concluded, “We have identified a novel pathway whereby FAK inhibition with VS6063 overcomes YB-1-mediated paclitaxel resistance by an AKT-dependent pathway. These findings have implications for clinical trials aimed at targeting FAK.” n Kang Y, et al: J Natl Cancer Inst 105:1485-1495, 2013.

Yoga Improves Sleep Quality in Patients With Cancer Suffering From Sleep Disruption By Matthew Stenger

I

t is estimated that 30% to 90% of patients with cancer experience impairment of sleep quality posttreatment, and such impairment can be severe enough to increase morbidity and mortality. Preliminary evidence indicates that yoga may improve sleep in cancer patients. In a study reported in the Journal of Clinical Oncology, Karen M. Mustian, PhD, MPH, of the University of Rochester Medical Center, and colleagues compared the effects of a standardized yoga intervention vs standard care on global sleep quality in patients with cancer experiencing sleep disruption.1 They found that yoga participants had sig-

nificantly greater improvements in global sleep quality, subjective sleep quality, daytime dysfunction, wake after sleep onset, sleep efficiency, and medication use.

Yoga, specifically the YOCAS program, is a useful treatment for improving sleep quality and reducing sleep medication use among cancer survivors.

Study Details In this study, 410 patients aged 21 years or older with moderate or greater sleep disruption between 2 and 24 months after surgery, chemotherapy, or radiation therapy were randomized to standard care (n = 204) or standard care plus a 4-week yoga intervention (n = 206). To be eligible for the study, patients must have completed treatment for cancer and must not have maintained a regular prac-

ing any form of treatment for cancer, with the exception of hormonal or monoclonal antibody therapy, and could not have metastatic cancer. The yoga intervention used the continued on page 117

mpaired sleep quality is a concerning problem for many patients with cancer, and pharmacologic treatments come with many negative effects. Several small studies indicate that yoga improves persistent fatigue, sleep disturbance, anxiety, and quality of life, in addition to reducing the need for sleep medication.1-5 A systematic review and meta-analyses found reductions in distress, anxiety, depression, and fatigue, but the effects on sleep were small and not significant.6 The recent study by Mustian and colleagues provides evidence for the use of a standardized multimodal yoga intervention to improve sleep quality.7

Mustian et al Study Design and Results Of 410 patients randomized in this study, 321 completed baseline and postintervention assessments. As a randomized, multicenter nationwide trial, this is considerably larger than most Dr. Wesa is an integrative medicine specialist with the Integrative Medicine Service; Ms. Benusis is a yoga therapist with the Integrative Medicine Service; and Dr. Cassileth is Chief of the Integrative Medicine Service and Laurance S. Rockefeller Chair in Integrative Medicine at Memorial SloanKettering Cancer Center, New York.

phase II yoga studies, which typically enroll 20 to 40 patients. The Mustian et al intervention—the Yoga for Cancer Survivors (YOCAS) program—included a sequence of gentle hatha yoga postures (asanas), passively held restorative yoga poses, specific breathing practices (pranayama), and meditation, compared with standard care. Intervention participants attended 75-minute sessions twice weekly for 4 weeks. Control participants received mainstream care to address sleep issues, and were offered the 4-week YOCAS program free of charge after study completion. Sleep quality for both groups was assessed using the Pittsburgh Sleep Quality Index and actigraphy (a validated, objective measure of sleep quality) preand postintervention. Compared with control participants, those randomized to the YOCAS arm reported significantly ­ greater improvement in the primary outcome of global sleep quality (P < .01), as well as secondary outcomes including daytime dysfunction (P < .01), subjective sleep quality, and use of sleep medication (P < .05 for both). Objective measures from actigraphy showed significantly greater improvements in wake after sleep onset and sleep efficiency (P < .01 for both).

For the 319 patients who completed the study, yoga participants reduced sleep medication use by 21% per week, while control participants increased usage by 5% per week. Investigators also found that patients across the symptom severity spectrum benefited, and that participants with very poor sleep efficiency benefited the most. These results were achieved even though the average “total dose” of yoga for the entire 4-week intervention was 80% of that prescribed.

Yoga Theory and Clinical Considerations Asana, pranayama, and meditation are core components of classical hatha yoga, which is part of the Indian Systems of Philosophy and closely related to Ayurveda, the traditional medical system of India. Restorative poses that use props such as blocks, bolsters, and blankets to facilitate total relaxation into a pose have evolved since the 1970s, most notably by the Iyengar style of yoga (a form of hatha yoga with an emphasis on detail, precision, and alignment in posture and breath control). The study authors note that the restorative component was selected on the basis of yoga theory that postulates its positive influence on sleep. Indeed, restorative postures allow for the experience of complete support

and deep relaxation. It also has been noted that such restorative postures, breathing techniques, and meditation encourage what is traditionally known as “pratyahara,” a turning inward of the senses that can modulate nervous system activity and subsequently improve sleep.8 That the intervention was conducted in the late afternoon or evening after 4:00 PM also fosters the practice of good sleep hygiene, which encourages control over behavioral and environmental factors prior to sleep. The objective use of actigraphy as a clinical endpoint as well as a standardized yoga intervention allow for more widespread generalization of trial results. While the authors identified posture, breath, and awareness as the unifying components in both hatha and restorative yoga, both the tempo of transitions and holding time also should be considered in future research. That said, one might weigh author comments that additional phase III trials are needed against the limited financial resources available for research and the high cost of performing large-scale trials. The significant proportion of patients lost to followup or not fully evaluable (22%) is in line with the attrition rate of other clinical trials of yoga. continued on page 116

Managing Sleep Disruption continued from page 114

Lifestyle Interventions Gaining Traction It may be unnecessary to wait for additional data to recommend yoga and other lifestyle interventions such as breathing practices, meditation, stress reduction, and physical exercise. These practices are well databased as effective treatments for disease-related symptoms including pain, dyspnea, digestion problems, skeletal issues, mobility and postural problems, depression, fatigue, anxiety, and sleep disturbance.9-15 Physical activity is well-documented as associated with survival benefits.16-19 Cancer patient engagement in symptom management and the recovery process is stronger than ever. Yoga, meditation, and exercise classes for cancer survivors are more routinely available throughout the country. Many of these modalities are self-selected by patients. But many patients require guidance on practices of self-care, especially with respect to nonpharmacologic interventions that help manage symptoms. Comprehensive lifestyle interventions that extend beyond a single application can provide significant clinical benefits,20-23 especially in impaired sleep quality and other problems that have many contributing factors. The hallmarks of these techniques are that they are easily taught, inexpensive, safe, and beneficial.

Compound Benefits As with other nonpharmacologic interventions, the YOCAS program engages participants in a lifestyle intervention. The risk of physical injury from participation in gentle supervised yoga sessions with experienced instructors is low, while the potential for clinical benefit is high. Adding an intervention such as YOCAS also may prove to be cost-effective in the long run, as some studies suggest that is the case for comparable modalities.24,25 It likely confers other benefits, as preliminary studies in other groups show that yoga reduces pain, improves cognition and cardiovascular function, and improves quality of life.26-28 Longterm practice may reduce inflammatory response to stress.29 Most yoga research in the oncology setting, including this study, tends to enroll women with breast cancer. Although data on other cancer patient subgroups may not yet be available, it

is likely that they too can benefit. As is true of most fitness programs, yoga is readily adaptable to a broad range of clinical levels and goals.

The use of nonpharmacologic interventions for symptom control can considerably empower cancer survivors in their pursuit to self-manage symptoms, improve self-care, and speed recovery. —Kathleen M. Wesa, MD, Lara Benusis, E-RYT 500, and Barrie R. Cassileth, MS, PhD

Conclusion In a busy practice, it can be tempting to prescribe medications for sleep disturbance, but these are not without side effects. The use of nonpharmacologic interventions for symptom control can considerably empower cancer survivors in their pursuit to self-manage symptoms, improve selfcare, and speed recovery. n

Yoga Improves Sleep Quality continued from page 114

Yoga for Cancer Survivors (YOCAS) program consisting of pranayama (breathing exercises), 16 gentle hatha and restorative yoga asanas (postures), and meditation. Participants attended two 75-minute sessions per week. Standard care consisted of standard follow-up care provided by treating oncologists as appropriate for patients’ individual diagnoses. The primary outcome measure was global sleep quality score on the Pittsburgh Sleep Quality Index (PSQI), and the subscale scores of global sleep quality characteristics were secondary endpoints. Objective sleep characteristics were assessed by actigraphy, a noninvasive method of monitoring human rest/activity cycles. There were no significant differences between yoga and standard care groups in age (mean, 54 years in both), sex (96% women in both), race/ethnicity (96% and 91% white), marital status (married or long-term committed relationship in 71% and 72%), education level (47% of both completed college), employment status (83% and 78% employed), cancer type (breast in 74% and 77%), cancer stage (I or II in 68% and 72%, III in 16% of both, IV in 4% and 2%), previous cancer treatments (surgery in 90% and 91%, chemotherapy in 72% and 70%, radiation therapy in 67% and 65%), current hormone therapy (49% and 54%), time since first cancer treatment (mean, 14.9 and 17.7 months), Karnofsky performance status (mean, 86.9 and 87.8), or exercise status (53% and 51% exercising for less than or more than 6 months). Yoga patients attended an aver-

age of 6.5 of the 8 prescribed sessions. Patients in the yoga group were told that they could practice the yoga they learned in class on their own; daily diaries showed that they had three sessions combining class-based and home-based yoga each week for an average of 182 minutes with a perceived exertion rating of 3.4 (moderate). In the control group, seven patients reported an average of 20 minutes of yoga one time each week with a perceived exertion rating of 1.0 (very weak) during the study period.

Improved Sleep Quality Both groups met the clinical cutoff criterion for impaired sleep quality at baseline with PSQI scores > 8. Compared with the control group, the yoga group had a significantly greater improvement in global sleep quality (P < .01). The PSQI global sleep quality score improved from a mean of 9.20 at baseline to 7.23 (–1.96 difference) in the yoga group compared with improvement from 8.96 to 7.89 (–1.07) in the control group. Yoga patients exhibited large improvements in sleep quality compared with baseline (effect size [d] = 0.62), suggesting that the improvement was clinically significant, whereas improvement from baseline in the control group was less robust (d = 0.37). Compared with the control group, the yoga group also had significantly greater improvements in the secondary outcome measures of daytime dysfunction (P < .01), subjective sleep quality (P < .05), and sleep medication use (P < .05). Yoga patients reduced sleep medication use by 21% per week, and control patients increased sleep medication use by 5% per week. Overall, 90% of the yoga group found yoga use-

ful for improving their sleep quality, with 100% stating that they would recommend yoga to other cancer survivors with sleep problems and 63% stating they would highly recommend it. Compared with baseline, the yoga group had significant improvements in sleep quality, including global sleep quality (P < .01), sleep latency (P < .01), sleep duration (P < .05), sleep efficiency (P < .01), sleep disturbances (P < .05), subjective sleep quality (P < .01), and daytime dysfunction (P < .01), but not sleep medication use. Compared with baseline, the control group had significant improvements in global sleep quality (P < .01), sleep efficiency (P < .05), sleep disturbance (P ≤ .01), and subjective sleep quality (P < .01), but not in sleep latency, sleep duration, daytime dysfunction, or sleep medication use.

Actigraphy Actigraphy studies showed that the yoga group had significantly greater improvements in wake after sleep onset (P < .01) and sleep efficiency (P < .01) compared with the control group. Patients in the yoga group who had 60 minutes or more of wakefulness after sleep onset or a sleep efficiency of ≤ 60% at baseline showed the greatest reductions in

wake after sleep onset and the greatest improvements in sleep efficiency. One patient had supraventricular tachycardia during the study period, which was considered grade 2 and unrelated to the study intervention. No other serious adverse events were reported. The investigators concluded, “Yoga, specifically the YOCAS program, is a useful treatment for improving sleep quality and reducing sleep medication use among cancer survivors.” They noted that further phase III studies are needed to replicate their findings, assess the effects of increased length and intensity of yoga, provide longterm follow-up of the sustainability of benefits, and to compare yoga with such established treatments as cognitive behavioral therapy and drug treatments. They also stated that additional research should examine the potential impact of yoga on cancer recurrence and survival rates. n Disclosure: The study was supported by the National Cancer Institute and the Office of Cancer Complementary and Alternative Medicine. The study authors reported no potential conflicts of interest.

Does not include costs related to office visit, physician, staff, or administrative charges associated with administering XGEVA®.


INDICATION XGEVA® is indicated for the prevention of skeletal-related events in patients with bone metastases from solid tumors. XGEVA® is not indicated for the prevention of skeletal-related events in patients with multiple myeloma.

IMPORTANT SAFETY INFORMATION Hypersensitivity • XGEVA is contraindicated in patients with clinically significant hypersensitivity to any component of the product. ®

Hypocalcemia

• XGEVA® can cause severe symptomatic hypocalcemia, and fatal cases have been reported. Correct pre-existing hypocalcemia prior to XGEVA® treatment. Monitor calcium levels and administer calcium, magnesium, and vitamin D as necessary. Monitor levels more frequently when XGEVA® is administered with other drugs that can also lower calcium levels. Advise patients to contact a healthcare professional for symptoms of hypocalcemia. • Based on clinical trials using a lower dose of denosumab, patients with a creatinine clearance less than 30 mL/min or receiving dialysis are at greater risk of severe hypocalcemia compared to patients with normal renal function. The risk of hypocalcemia at the recommended dosing schedule of 120 mg every 4 weeks has not been evaluated in patients with a creatinine clearance less than 30 mL/min or receiving dialysis.

Osteonecrosis of the Jaw (ONJ)

• Osteonecrosis of the jaw (ONJ) can occur in patients receiving XGEVA®, manifesting as jaw pain, osteomyelitis, osteitis, bone erosion, tooth or periodontal infection, toothache, gingival ulceration, or gingival erosion. Persistent pain or slow healing of the mouth or jaw after dental surgery may also be manifestations of ONJ. • In clinical trials in patients with osseous metastasis, 2.2% of patients receiving XGEVA® developed ONJ after a median exposure of 13 doses; of these patients, 79% had a history of tooth extraction, poor oral hygiene, or use of a dental appliance. In a clinical trial conducted in patients with prostate cancer at high risk for osseous metastasis, a condition for which denosumab is not approved, 5.4% of patients developed ONJ after a median exposure of 20 doses. • Perform an oral examination and appropriate preventive dentistry prior to the initiation of XGEVA® and periodically during XGEVA® therapy. Advise patients regarding oral hygiene practices. Avoid invasive dental procedures during treatment with XGEVA®.

• Patients who are suspected of having or who develop ONJ while on XGEVA® should receive care by a dentist or an oral surgeon. In these patients, extensive dental surgery to treat ONJ may exacerbate the condition.

Atypical Subtrochanteric and Diaphyseal Femoral Fracture • Atypical femoral fracture has been reported with XGEVA®. Causality has not been established as these fractures also occur in osteoporotic patients who have not been treated with anti-resorptive agents. A number of reports note that patients were also receiving treatment with glucocorticoids at the time of fracture. Any patient who presents with thigh or groin pain should be suspected of having an atypical fracture and should be evaluated to rule out an incomplete femur fracture. Interruption of XGEVA® therapy should be considered, pending a risk/ benefit assessment, on an individual basis.

Embryo-Fetal Toxicity

• XGEVA® can cause fetal harm when administered to a pregnant woman. Based on findings in animals, XGEVA® is expected to result in adverse reproductive effects. • Advise females of reproductive potential to use highly effective contraception during therapy, and for at least 5 months after with the last dose of XGEVA®. Apprise the patient of the potential hazard to a fetus if XGEVA® is used during pregnancy or if the patient becomes pregnant while patients are exposed to XGEVA®.

Adverse Reactions

• The most common adverse reactions in patients receiving XGEVA® with bone metastasis from solid tumors were fatigue/asthenia, hypophosphatemia, and nausea. The most common serious adverse reaction was dyspnea. The most common adverse reactions resulting in discontinuation were osteonecrosis and hypocalcemia.

randomized to receive either 120 mg of Xgeva every 4 weeks as a subcutaneous injection or 4 mg (dose adjusted for reduced renal function) of zoledronic acid every 4 weeks by intravenous (IV) infusion. Entry criteria included serum calcium (corrected) from 8 to 11.5 mg/dL (2 to 2.9 mmol/L) and creatinine clearance 30 mL/min or greater. Patients who had received IV bisphosphonates were excluded, as were patients with prior history of ONJ or osteomyelitis of the jaw, an active dental or jaw condition requiring oral surgery, non-healed dental/oral surgery, or any planned invasive dental procedure. During the study, serum chemistries including calcium and phosphorus were monitored every 4 weeks. Calcium and vitamin D supplementation was recommended but not required. The median duration of exposure to Xgeva was 12 months (range: 0.1 – 41) and median duration on-study was 13 months (range: 0.1 – 41). Of patients who received Xgeva, 46% were female. Eighty-five percent were White, 5% Hispanic/Latino, 6% Asian, and 3% Black. The median age was 63 years (range: 18 – 93). Seventy-five percent of patients who received Xgeva received concomitant chemotherapy.

Preparation and Administration. Visually inspect Xgeva for particulate matter and Table 1. Per-patient Incidence of Selecteda Adverse Reactions of Any discoloration prior to administration. Xgeva is a clear, colorless to pale yellow solution that Severity (Trials 1, 2, and 3) may contain trace amounts of translucent to white proteinaceous particles. Do not use xgeva Zoledronic Acid if the solution is discolored or cloudy or if the solution contains many particles or foreign n = 2841 n = 2836 particulate matter. Prior to administration, Xgeva may be removed from the refrigerator Body System % % and brought to room temperature (up to 25°C/77°F) by standing in the original container. This generally takes 15 to 30 minutes. Do not warm Xgeva in any other way (see How GASTROINTESTINAL Supplied/Storage and Handling). Use a 27-gauge needle to withdraw and inject the Nausea 31 32 entire contents of the vial. Do not re-enter the vial. Discard vial after single-use or entry. Diarrhea 20 19 CONTRAINDICATIONS: GE NERAL Hypersensitivity. Xgeva is contraindicated in patients with clinically significant Fatigue/ Asthenia 45 46 hypersensitivity to any component of the product (see Adverse Reactions). WARNINGS AND PRECAUTIONS: Hypocalcemia. XGEVA can cause severe symptomatic hypocalcemia, and fatal cases have been reported. Correct pre-existing hypocalcemia prior to Xgeva treatment. Monitor calcium levels and administer calcium, magnesium, and vitamin D as necessary. Monitor levels more frequently when Xgeva is administered with other drugs that can also lower calcium levels. In the postmarketing setting, severe symptomatic hypocalcemia has been reported (see Adverse Reactions). Advise patients to contact a healthcare professional for symptoms of hypocalcemia (see Adverse Reactions and Patient Counseling Information [17] in full Prescribing Information). Based on clinical trials using a lower dose of denosumab, patients with a creatinine clearance less than 30 mL/min or receiving dialysis are at greater risk of severe hypocalcemia compared to patients with normal renal function. In a trial of 55 patients, without cancer and with varying degrees of renal impairment, who received a single dose of 60 mg denosumab, 8 of 17 patients with a creatinine clearance less than 30 mL/min or receiving dialysis experienced corrected serum calcium levels less than 8.0 mg/dL as compared to 0 of 12 patients with normal renal function. The risk of hypocalcemia at the recommended dosing schedule of 120 mg every 4 weeks has not been evaluated in patients with a creatinine clearance less than 30 mL/min or receiving dialysis.

Osteonecrosis of the Jaw In the primary treatment phases of Trials 1, 2, and 3, ONJ was confirmed in 1.8% of patients in the Xgeva group and 1.3% of patients in the zoledronic acid group (see Warnings and Precautions). When events occurring during an extended Atypical Subtrochanteric and Diaphyseal Femoral Fracture. Atypical femoral treatment phase of approximately 4 months in each trial are included, the fracture has been reported with Xgeva (see Adverse Reactions). These fractures can incidence of confirmed ONJ was 2.2% in patients who received Xgeva. The Geriatric Use. Of patients who received Xgeva in Trials 1, 2, and 3, 1260 (44%) were 65 years of age or older.

Because postmarketing reactions are reported observed between these patients and younger patients. oral hygiene practices. Avoid invasive dental procedures during treatment with Xgeva. Patients who are suspected of having or who develop ONJ while on Xgeva should receive care by a dentist or an oral surgeon. In these patients, extensive dental surgery to treat ONJ may exacerbate the condition.

evidence of comminution. Causality has not been established as these fractures also occur in osteoporotic patients who have not been treated with anti-resorptive agents. Atypical femoral fractures most commonly occur with minimal or no trauma to the affected area. They may be bilateral and many patients report prodromal pain in the affected area, usually presenting as dull, aching thigh pain, weeks to months before a complete fracture occurs. A number of reports note that patients were also receiving treatment with glucocorticoids (e.g. prednisone) at the time of fracture. During Xgeva treatment, patients should be advised to report new or unusual thigh, hip, or groin pain. Any patient who presents with thigh or groin pain should be suspected of having an atypical fracture and should be evaluated to rule out an incomplete femur fracture. Patient presenting with an atypical femur fracture should also be assessed for symptoms and signs of fracture in the contralateral limb. Interruption of Xgeva therapy should be considered, pending a risk/benefit assessment, on an individual basis. EMBRyO-FETAL TOxICITy: Xgeva can cause fetal harm when administered to a pregnant woman. Based on findings in animals, Xgeva is expected to result in adverse reproductive effects. In utero denosumab exposure in cynomolgus monkeys resulted in increased fetal loss, stillbirths, and postnatal mortality, along with evidence of absent peripheral lymph nodes, abnormal bone growth, and decreased neonatal growth (see Use in Specific Populations). Advise females of reproductive potential to use highly effective contraception during therapy, and for at least 5 months after with the last dose of Xgeva. Apprise the patient of the potential hazard to a fetus if Xgeva is used during pregnancy or if the patient becomes pregnant while patients are exposed to Xgeva. Advise patients to contact their healthcare provider if they become pregnant or a pregnancy is suspected during this time (see Use in Specific Populations).

voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. The following adverse reactions have been identified during post approval use of Xgeva: • Hypocalcemia: Severe symptomatic hypocalcemia, including fatal cases.

Immunogenicity. As with all therapeutic proteins, there is potential for immunogenicity. Using an electrochemiluminescent bridging immunoassay, less than 1% (7/2758) of patients with osseous metastases treated with denosumab doses ranging from 30 – 180 mg every 4 weeks or every 12 weeks for up to 3 years tested positive for binding antibodies. No patient with positive binding antibodies tested positive for neutralizing antibodies as assessed using a chemiluminescent cell-based in vitro biological assay. There was no evidence of altered pharmacokinetic profile, toxicity profile, or clinical response associated with binding antibody development. The incidence of antibody formation is highly dependent on the sensitivity and specificity of the assay. Additionally, the observed incidence of a positive antibody (including neutralizing antibody) test result may be influenced by several factors, including assay methodology, sample handling, timing of sample collection, concomitant medications, and underlying disease. For these reasons, comparison of antibodies to denosumab with the incidence of antibodies to other products may be misleading.

DRUG INTERACTIONS: No formal drug-drug interaction trials have been conducted with Xgeva. In clinical trials in patients with breast cancer metastatic to bone, Xgeva was administered in combination with standard anticancer treatment. Serum denosumab concentrations at 1 and 3 months and reductions in the bone turnover marker uNTx/Cr (urinary N-terminal telopeptide corrected for creatinine) at 3 months were similar in patients with and without prior intravenous bisphosphonate therapy. There ADVERSE REACTIONS: The following adverse reactions are discussed below and was no evidence that various anticancer treatments affected denosumab systemic elsewhere in the labeling: exposure and pharmacodynamic effect.

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in other clinical trials and may not reflect the rates observed in practice. The safety of Xgeva was evaluated in three randomized, double-blind, double-dummy trials (see Clinical Trials [14] in full Prescribing Information) in which a total of 2841 patients with bone metastasis from prostate cancer, breast cancer, or other solid tumors, or lytic bony lesions from multiple myeloma received at least one dose of Xgeva. In Trials 1, 2, and 3, patients were

Renal Impairment. In a trial of 55 patients without cancer and with varying degrees of renal function who received a single dose of 60 mg denosumab, patients with a creatinine clearance of less than 30 mL/min or receiving dialysis were at greater risk of severe hypocalcemia with denosumab compared to patients with normal renal function. The risk of hypocalcemia at the recommended dosing schedule of 120 mg every 4 weeks has not been evaluated in patients with a creatinine clearance of less than 30 mL/min or receiving dialysis (see Warnings and Precautions, Adverse Reactions, and Clinical Pharmacology [12.3] in full Prescribing Information). OVERDOSAGE: There is no experience with overdosage of Xgeva. HOW SUPPLIED/STORAGE AND HANDLING: Xgeva is supplied in a single-use vial. Store Xgeva in a refrigerator at 2°C to 8°C (36°F to 46°F) in the original carton. Do not freeze. Once removed from the refrigerator, Xgeva must not be exposed to temperatures above 25°C/77°F or direct light and must be used within 14 days. Discard Xgeva if not used within the 14 days. Do not use Xgeva after the expiry date printed on the label. Protect Xgeva from direct light and heat. Avoid vigorous shaking of Xgeva. PATIENT COUNSELING INFORMATION: Advise patients to contact a healthcare professional for any of the following: • Symptoms of hypocalcemia, including paresthesias or muscle stiffness, twitching, spasms, or cramps (see Warnings and Precautions and Adverse Reactions) • Symptoms of ONJ, including pain, numbness, swelling of or drainage from the jaw, mouth, or teeth (see Warnings and Precautions and Adverse Reactions) • Persistent pain or slow healing of the mouth or jaw after dental surgery (see Warnings and Precautions) • Pregnancy or nursing (see Warnings and Precautions and Use in Specific Populations)

Advise patients of the need for: • Proper oral hygiene and routine dental care • Informing their dentist that they are receiving Xgeva • Avoiding invasive dental procedures during treatment with Xgeva • The use of highly effective contraception during and for at least 5 months after treatment with Xgeva for females of reproductive potential animals.

There are no adequate and well-controlled studies with Xgeva in pregnant women. Women should be advised not Amgen Manufacturing Limited, a subsidiary of Amgen Inc. to become pregnant when taking Xgeva. If this drug is used during pregnancy, or if the One Amgen Center Drive patient becomes pregnant while taking this drug, the patient should be apprised of the Thousand Oaks, California 91320-1799 potential hazard to the fetus.

Clinical Considerations: The effects of Xgeva are likely to be greater during the second and third trimesters of pregnancy. Monoclonal antibodies are transported across the placenta in a linear fashion as pregnancy progresses, with the largest amount transferred during the third trimester. If the patient becomes pregnant during Xgeva therapy, consider the risks and benefits in continuing or discontinuing treatment with Xgeva. Animal Data: The effects of denosumab on prenatal development have been studied in both cynomolgus monkeys and genetically engineered mice in which RANK ligand (RANKL) expression was turned off by gene removal (a “knockout mouse”). In cynomolgus monkeys dosed subcutaneously with denosumab throughout pregnancy at a pharmacologically active dose, there was increased fetal loss during gestation, stillbirths, and postnatal mortality. Other findings in offspring included absence of axillary, inguinal, mandibular, and mesenteric lymph nodes; abnormal bone growth, reduced bone strength, reduced hematopoiesis, dental dysplasia and tooth malalignment; and decreased neonatal growth. At birth out to one month of age, infants had measurable blood levels of denosumab (22-621% of maternal levels). Following a recovery period from birth out to 6 months of age, the effects on bone quality and strength returned to normal; there were no adverse effects on tooth eruption, though dental dysplasia was still apparent; axillary and inguinal lymph nodes remained absent, while mandibular and mesenteric lymph nodes were present, though small; and minimal to moderate mineralization in multiple tissues was seen in one recovery animal. There was no evidence of maternal harm prior to labor; adverse maternal effects occurred infrequently during labor. Maternal mammary gland development was normal. There was no fetal NOAEL (no observable adverse effect level) established for this study because only one dose of 50 mg/kg was evaluated. In RANKL knockout mice, absence of RANKL (the target of denosumab) also caused fetal lymph node agenesis and led to postnatal impairment of dentition and bone growth. Pregnant RANKL knockout mice showed altered maturation of the maternal mammary gland, leading to impaired lactation (see Use in Nursing Mothers and Nonclinical Toxicology [13.2] in full Prescribing Information). Nursing Mothers. It is not known whether Xgeva is excreted into human milk. Measurable concentrations of denosumab were present in the maternal milk of cynomolgus monkeys up to 1 month after the last dose of denosumab (≤ 0.5% milk:serum ratio). Because many drugs are excreted in human milk and because of the potential for serious adverse reactions in nursing infants from Xgeva, a decision should be made whether to discontinue nursing or discontinue the drug, taking into account the importance of the drug to the mother. Maternal exposure to Xgeva during pregnancy may impair mammary gland development and lactation based on animal studies in pregnant mice lacking the RANK/RANKL signaling pathway that have shown altered maturation of the maternal mammary gland, leading to impaired lactation postpartum. However, in cynomolgus monkeys treated with denosumab throughout pregnancy, maternal mammary gland development was normal, with no impaired lactation. Mammary gland histopathology at 6 months of age was normal in female offspring exposed to denosumab in utero; however, development and lactation have not been fully evaluated (see Nonclinical Toxicology [13.2] in Full Prescribing Information). Pediatric Use. Xgeva is not recommended in pediatric patients. The safety and effectiveness of Xgeva in pediatric patients have not been established. Treatment with Xgeva may impair bone growth in children with open growth plates and may inhibit eruption of dentition. In neonatal rats, inhibition of RANKL (the target of Xgeva therapy) with a construct of osteoprotegerin bound to Fc (OPG-Fc) at doses ≤ 10 mg/kg was associated with inhibition of bone growth and tooth eruption. Adolescent primates treated with denosumab at doses 5 and 25 times (10 and 50 mg/kg dose) higher than the recommended human dose of 120 mg administered once every 4 weeks, based on body weight (mg/kg), had abnormal growth plates, considered to be consistent with the pharmacological activity of denosumab. Cynomolgus monkeys exposed in utero to denosumab exhibited bone abnormalities, reduced hematopoiesis, tooth malalignment, decreased neonatal growth, and an absence of axillary, inguinal, mandibular, and mesenteric lymph nodes. Some bone abnormalities recovered once exposure was ceased following birth; however, axillary and inguinal lymph nodes remained absent 6 months post-birth (see Use in Pregnancy).

ASCO State Affiliates Focus on the Texas Society of Clinical Oncology By Jo Cavallo

The ASCO Post spoke with TxSCO President Gladys Rodriguez, MD, about the Society’s past accomplishments and its future goals.

Part of a Larger Community

Gladys Rodriguez, MD

T

he second largest state in the nation (after Alaska), Texas covers a total area of 268,581 square miles and has a diverse population of over 26 million people. In 1987, the Texas Society of Medical Oncology, now the Texas Society of Clinical Oncology (TxSCO), was formed to address the oncology needs of Texas residents. With over 500 members, which include more than 450 hematology and medical oncologists from every discipline as well as nurses, social workers, and pharmacists, TxSCO is among the largest and oldest of ASCO’s State Affiliates, officially becoming a State Affiliate in 1994. The Society is also the largest organization in the state representing oncologists.

Why was it important for TxSCO to become an ASCO State Affiliate? Initially, the Society was formed to represent medical and radiation oncologists, but about 4 years ago the bylaws were changed to include other oncology professionals who help in the care of patients with cancer, such as nurses, pharmacists, and social workers. Texas is a very large state with a diverse population living in both rural and urban cities. We have a large Hispanic population and a huge underserved and underinsured population, so ensuring quality care for every patient can be challenging. Being an ASCO State Affiliate allows us to collaborate with physicians both in community practices and academic cancer centers to improve oncology care for patients. It also gives us the opportunity to have a national platform and to work with other State Affiliates that might have similar problems so we can learn from other groups, share resources, and be part of a larger community.

ASCO Daily News Seeks New Editor The American Society of Clinical Oncology is seeking candidates for Editor of the ASCO Daily News. The 5-year term will begin as of June 2014. The ASCO Daily News is the official daily news source of the ASCO Annual Meeting. Content in electronic and print formats includes live coverage of scientific highlights, editorials by leaders in the field, information about ASCO products and resources, and video interviews with key thought leaders regarding timely and essential topics. The Editor will be responsible for providing leadership and strategic vision for the ASCO Daily News, as well as editorial oversight for the content of both the print and electronic formats. Candidates must be ASCO members. Interested candidates or those wishing to nominate a candidate should submit a letter of interest, along with a curriculum vitae, to the ASCO Daily News Managing Editor Joy Curzio (Joy.Curzio@asco.org) by November 30, 2013. Selected candidates will receive further information regarding the application process from the ASCO Daily News Editor Search Committee.

Addressing Challenges What are some of the challenges you face that are unique to Texas? Because our state is so large, patients living in rural areas may have to travel 300 or 400 miles to find oncology care, and the care may be uneven because some areas lack the resources oncology practices in larger cities have. Our mission is to provide advocacy for cancer patients and to promote standards of excellence for high-quality cancer care. The theme of our annual meeting in September was Changes in Oncology: How to Improve Care. We had sessions on ASCO’s Quality Oncology Practice Initiative (QOPI®), implementation of the Centers for Medicare & Medicaid Services ICD10 codes, genomics and cancer care,

and how to ensure patient access to treatment. We provide information on our website to help patients and private oncology practices find the latest information on changes to health-care laws and to Medicare and Medicaid. We also post clinical trial details and patient assistance and reimbursement resources.

Public Policy Activities How active is TxSCO in crafting or advocating public policy? We are very active. We have a legislative committee, which studies issues relevant to our patients and physicians, and we partner with other societies and groups like the Texas Medical Association to ensure that all medical decisions remain between the physician and patient. We also use a lobbying group called HillCo Partners to help us with changes to laws proposed by the Texas legislature, including Medicaid issues, and in providing information to patients about the Patient Protection and Affordable Care Act and how to access the health insurance exchanges. Texas has opted out of creating a state-based health insurance marketplace, so we are evaluating how we can help patients access the federally created marketplace. What legislative successes have you had? One of the first pieces of legislation we championed was the Oral Chemotherapy Drug Parity bill Texas passed into law in 2011. We also were instrumental in helping low-income, uninsured women diagnosed with breast or cervical cancer get medical assistance through the Medicaid for Breast and Cervical Cancer program. In 2007, any woman diagnosed with continued on page 122

Is TxSCO currently involved in other public policy issues? Yes. In 2009, the Cancer Prevention and Research Institute of Texas (CPRIT) was created to issue $3 billion in bonds to fund groundbreaking

cancer research programs throughout the state. Several of TxSCO’s board members worked with CPRIT to establish a statewide clinical trials network so promising cancer treatments could be matched with the genetic makeup of a patient’s tumor and the patient could be immediately enrolled in the trial.

Why is it necessary for ASCO members to belong to a State Affiliate? I know that probably not every ASCO member belongs to a State Affiliate, and I’d like members to know that there are state societies available to them. It’s important to join a state society because it makes you aware of the problems colleagues and patients in your local community are dealing with. It also provides a forum to find common solutions that could help not only the individual practitioner, but also colleagues across the state. You can then use ASCO’s resources to help solve some of those problems. n

We were very proactive with major cancer centers, including MD Anderson Cancer Center and Baylor Charles A. Sammons Cancer Center, to liaison with the medical and patient communities to ensure that patients had access to those clinical trials. Unfortunately, the program is on hold due to some accountability issues involving how CPRIT picked projects. But reforms have since been put in place so, hopefully, CPRIT will soon begin taking new grant applications and the clinical trials program will resume.

Awards Tobacco Cessation

IOM Presents 2013 Lienhard Award to Leader of Smoking Cessation and Tobacco Prevention Efforts

T

he Institute of Medicine has (IOM) presented the 2013 Gustav O. Lienhard Award to Steven A. Schroeder, MD, whose pioneering efforts to control tobacco use have helped save millions from premature, smoking-related deaths. The award

Steven A. Schroeder, MD

also recognizes Dr. Schroeder’s leadership in general medicine as well as his work to improve end-of-life care. “It is my great privilege to present this award to a dedicated champion of health for Americans and citizens around the world,” said IOM President Harvey V. Fineberg. “Dr. Schroeder’s perseverance in funding tobacco research and creating breakthrough strategies to help smokers quit facilitated a shift in public attitudes toward smoking and shaped policies to prevent smoking.”

Initiated Smoking Cessation Efforts As president of the Robert Wood Johnson Foundation from 1990 to 2002, Dr. Schroeder established and led programs to reduce smoking, enhance end-of-life care, expand health

insurance for children, and encourage physical activity. His most influential initiative focused on leveraging research, policy, advocacy, and education to reduce tobacco use and drive systemwide changes that created higher tobacco taxes, smoke-free indoor air laws, and better access to addiction treatment. Robert Wood Johnson Foundation tobacco research was cited in the formulation of and advocacy for such policy adoption. The impact of anti-smoking campaigns by the Robert Wood Johnson Foundation and its partners was profound. Smoking rates among adults declined from 25.5% in 1993 to 18% in 2011, meaning that 5.3 million fewer people were smoking and more than 60,000 smoking-related deaths had been avoided by 2010. At Robert Wood Johnson Foun-

a series of national programs to improve such care at hospitals. Bringing together physicians, nurses, palliative care experts, clergy, and patients, the initiative attempted to minimize legal barriers to prescribing pain medications at the end of life, expand hospice and hospital-based palliative care, energize patient groups, and work with hospital chaplains. As a result, more than 500 hospitals have received training in palliative care and many have instituted their own programs.

Founded Smoking Cessation Leadership Center Upon leaving Robert Wood Johnson Foundation and returning in 2003 to the University of California, San Francisco -- he was originally on the faculty from 1976 to 1990 – Dr. Schro-

[Dr. Schroeder’s] most influential initiative focused on leveraging research, policy, advocacy, and education to reduce tobacco use and drive systemwide changes that created higher tobacco taxes, smoke-free indoor air laws, and better access to addiction treatment. dation, Dr. Schroeder also funded the Dartmouth Atlas of Health Care, which was influential in documenting large regional variations in medical services that do not correlate to desired health-care outcomes. Furthermore, after negative results from a controlled trial to improve care for seriously ill hospital patients, known as the SUPPORT study, Dr. Schroeder instituted

eder continued his dedication to curbing tobacco use by founding the Smoking Cessation Leadership Center. Under his direction, the center aims to increase the cessation rate of smokers and the number of clinicians who help smokers quit by creating partnerships to develop and implement action plans. By working with leaders at more than 80 health organizations na-

tionwide, the center has expanded the types of groups that support smokers’ attempts to quit, such as dental hygienists, pharmacists, emergency physicians, and nurses; created new ways to market toll-free telephone quit lines; and engaged the mental health community in treating tobacco addiction. Dr. Schroeder earned his his medical degree from Harvard Medical School. He trained in internal medicine at the Harvard Medical Service of Boston City Hospital and in epidemiology as an epidemic intelligence service officer at the Centers for Disease Control and Prevention. Dr. Schroeder is the past chair of the American Legacy Foundation (now known as Legacy for Health), which in 2006 established the Schroeder Institute for Tobacco Research and Policy Studies in his honor. He was elected to the IOM in 1982 and is the former chair of IOM’s Board on Health Care Services. Dr. Schroeder is the 28th recipient of the Lienhard Award, which includes a medal and $40,000 prize. Given annually, the award recognizes outstanding achievement in improving personal health care services in the United States. Nominees are eligible for consideration without regard to education or profession, and award recipients are selected by a committee of experts convened by the IOM. This year’s selection committee was chaired by Raynard S. Kington, president of Grinnell College. Additional information about the Lienhard Award can be found at http://www.iom.edu/lienhard. n

FDA Update

FDA Approves Transducer Array Layout System for Use in Patients With Recurrent Glioblastoma Multiforme

N

ovocure recently announced that it has received FDA approval for its NovoTAL (Transducer Array Layout) System through a Premarket Approval supplement. The NovoTAL

System allows certified physicians to use the individual magnetic resonance imaging data of recurrent glioblastoma multiforme patients to optimize the field distribution and intensity of tumor treating fields (TTF) therapy.

NovoTAL System The NovoTAL System is a workstation-based software tool that uses

MRI head morphology, tumor size and location measurements, and tissue dielectric properties to optimize tumor treating field distribution and intensity within the brain tumor.

NovoTTF-100A System In 2011, the FDA approved Novocure’s NovoTTF-100A System, a noninvasive medical device that

produces a low-intensity, alternating electric field within a tumor, resulting in malignant cell death. The device is approved in the treatment of adult patients aged 22 and older with histologically confirmed glioblastoma multiforme, following confirmed recurrence in an upper region of the brain after receiving chemotherapy. n

Indications and Usage Jakafi is indicated for treatment of patients with intermediate or high-risk myelofibrosis, including primary myelofibrosis, post–polycythemia vera myelofibrosis and post–essential thrombocythemia myelofibrosis.

Important Safety Information • Treatment with Jakafi can cause thrombocytopenia, anemia and neutropenia, which are each dose-related effects, with the most frequent being thrombocytopenia and anemia. Perform a pre-treatment complete blood count (CBC) and monitor CBCs every 2 to 4 weeks until doses are stabilized, and then as clinically indicated • Thrombocytopenia was generally reversible and was usually managed by reducing the dose or temporarily interrupting Jakafi. Platelet transfusions may be necessary Jakafi is a registered trademark of Incyte Corporation. © 2013, Incyte Corporation. All rights reserved. RUX-1282b 09/13

• Patients developing anemia may require blood transfusions and/or dose modifications of Jakafi • Severe neutropenia (ANC <0.5 × 109/L) was generally reversible. Withhold Jakafi until recovery • The three most frequent non-hematologic adverse reactions were bruising, dizziness and headache • Serious bacterial, mycobacterial, fungal and viral infections may occur. Active serious infections should have resolved before starting Jakafi. Observe patients receiving Jakafi for signs and symptoms of infection and initiate appropriate treatment promptly. Advise patients about early signs and symptoms of herpes zoster and to seek early treatment

• Progressive multifocal leukoencephalopathy (PML) has been reported with ruxolitinib treatment for myelofibrosis. If PML is suspected, stop Jakafi and evaluate • A dose modification is recommended when administering Jakafi with strong CYP3A4 inhibitors or in patients with renal or hepatic impairment. Patients should be closely monitored and the dose titrated based on safety and efficacy • Use of Jakafi during pregnancy is not recommended and should only be used if the potential benefit justifies the potential risk to the fetus. Women taking Jakafi should not breast-feed Please see Brief Summary of Full Prescribing Information for Jakafi on the following page.

As studied in COMFORT-I, a randomized, double-blind, placebo-controlled phase III study with 309 total patients. The primary endpoint was the proportion of subjects achieving a ≥35% reduction in spleen volume from baseline to Week 24. A secondary endpoint was the proportion of subjects with a ≥50% reduction in TSS from baseline to Week 24.4,5 b TSS was captured by a daily patient diary (MFSAF v2.0). TSS encompasses debilitating symptoms of myelofibrosis: abdominal discomfort, early satiety, pain under left ribs, pruritus, night sweats and bone/muscle pain. Symptom scores ranged from 0 to 10 with 0 representing symptoms “absent” and 10 representing “worst imaginable” symptoms. These scores were added to create the daily total score, which has a maximum of 60. At baseline, mean TSS was 18.0 in the Jakafi group and 16.5 in the placebo group.4,5 a

WARNINGS AND PRECAUTIONS Thrombocytopenia, Anemia and Neutropenia Treatment with Jakafi can cause thrombocytopenia, anemia and neutropenia. [see Dosage and Administration (2.1) in Full Prescribing Information]. Thrombocytopenia was generally reversible and was usually managed by reducing the dose or temporarily interrupting Jakafi. Platelet transfusions may be necessary [see Dosage and Administration (2.2) in Full Prescribing Information, and Adverse Reactions]. Patients developing anemia may require blood transfusions and/or dose modifications of Jakafi. Severe neutropenia (ANC less than 0.5 X 109/L) was generally reversible. Withhold Jakafi until recovery [see Adverse Reactions]. Perform a pretreatment complete blood count (CBC) and monitor CBCs every 2 to 4 weeks until doses are stabilized, and then as clinically indicated [see Dosage and Administration (2.2) in Full Prescribing Information, and Adverse Reactions]. Risk of Infection Serious bacterial, mycobacterial, fungal and viral infections may occur. Active serious infections should have resolved before starting therapy with Jakafi. Observe patients receiving Jakafi for signs and symptoms of infection and initiate appropriate treatment promptly. PML Progressive multifocal leukoencephalopathy (PML) has been reported with ruxolitinib treatment for myelofibrosis. If PML is suspected, stop Jakafi and evaluate. Herpes Zoster Advise patients about early signs and symptoms of herpes zoster and to seek treatment as early as possible if suspected [see Adverse Reactions]. ADVERSE REACTIONS The following serious adverse reactions are discussed in greater detail in other sections of the labeling: • Myelosuppression [see Warnings and Precautions]; • Risk of Infection [see Warnings and Precautions] Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. The safety of Jakafi was assessed in 617 patients in six clinical studies with a median duration of follow-up of 10.9 months, including 301 patients with myelofibrosis in two Phase 3 studies. In these two Phase 3 studies, patients had a median duration of exposure to Jakafi of 9.5 months (range 0.5 to 17 months), with 88.7% of patients treated for more than 6 months and 24.6% treated for more than 12 months. One hundred and eleven (111) patients started treatment at 15 mg twice daily and 190 patients started at 20 mg twice daily. In a double-blind, randomized, placebo-controlled study of Jakafi, 155 patients were treated with Jakafi. The most frequent adverse drug reactions were thrombocytopenia and anemia [see Table 2]. Thrombocytopenia, anemia and neutropenia are dose related effects. The three most frequent non-hematologic adverse reactions were bruising, dizziness and headache [see Table 1]. Discontinuation for adverse events, regardless of causality, was observed in 11.0% of patients treated with Jakafi and 10.6% of patients treated with placebo. Following interruption or discontinuation of Jakafi, symptoms of myelofibrosis generally return to pretreatment levels over a period of approximately 1 week. There have been isolated cases of patients discontinuing Jakafi during acute intercurrent illnesses after which the patient’s clinical course continued to worsen; however, it has not been established whether discontinuation of therapy contributed to the clinical course in these patients. When discontinuing therapy for reasons other than thrombocytopenia, gradual tapering of the dose of Jakafi may be considered [see Dosage and Administration (2.9) in Full Prescribing Information]. Table 1 presents the most common adverse reactions occurring in patients who received Jakafi in the double-blind, placebo-controlled study during randomized treatment.

Description of Selected Adverse Drug Reactions Anemia In the two Phase 3 clinical studies, median time to onset of first CTCAE Grade 2 or higher anemia was approximately 6 weeks. One patient (0.3%) discontinued treatment because of anemia. In patients receiving Jakafi, mean decreases in hemoglobin reached a nadir of approximately 1.5 to 2.0 g/dL below baseline after 8 to 12 weeks of therapy and then gradually recovered to reach a new steady state that was approximately 1.0 g/dL below baseline. This pattern was observed in patients regardless of whether they had received transfusions during therapy. In the randomized, placebo-controlled study, 60% of patients treated with Jakafi and 38% of patients receiving placebo received red blood cell transfusions during randomized treatment. Among transfused patients, the median number of units transfused per month was 1.2 in patients treated with Jakafi and 1.7 in placebo treated patients. Thrombocytopenia In the two Phase 3 clinical studies, in patients who developed Grade 3 or 4 thrombocytopenia, the median time to onset was approximately 8 weeks. Thrombocytopenia was generally reversible with dose reduction or dose interruption. The median time to recovery of platelet counts above 50 X 109/L was 14 days. Platelet transfusions were administered to 4.7% of patients receiving Jakafi and to 4.0% of patients receiving control regimens. Discontinuation of treatment because of thrombocytopenia occurred in 0.7% of patients receiving Jakafi and 0.9% of patients receiving control regimens. Patients with a platelet count of 100 X 109/L to 200 X 109/L before starting Jakafi had a higher frequency of Grade 3 or 4 thrombocytopenia compared to patients with a platelet count greater than 200 X 109/L (16.5% versus 7.2%). Neutropenia In the two Phase 3 clinical studies, 1.0% of patients reduced or stopped Jakafi because of neutropenia. Table 2 provides the frequency and severity of clinical hematology abnormalities reported for patients receiving treatment with Jakafi or placebo in the placebo-controlled study.

Additional Data from the Placebo-controlled Study 25.2% of patients treated with Jakafi and 7.3% of patients treated with placebo developed newly occurring or worsening Grade 1 abnormalities in alanine transaminase (ALT). The incidence of greater than or equal to Grade 2 elevations was 1.9% for Jakafi with 1.3% Grade 3 and no Grade 4 ALT elevations. 17.4% of patients treated with Jakafi and 6.0% of patients treated with placebo developed newly occurring or worsening Grade 1 abnormalities in aspartate transaminase (AST). The incidence of Grade 2 AST elevations was 0.6% for Jakafi with no Grade 3 or 4 AST elevations. 16.8% of patients treated with Jakafi and 0.7% of patients treated with placebo developed newly occurring or worsening Grade 1 elevations in cholesterol. The incidence of Grade 2 cholesterol elevations was 0.6% for Jakafi with no Grade 3 or 4 cholesterol elevations. DRUG INTERACTIONS Drugs That Inhibit or Induce Cytochrome P450 Enzymes Ruxolitinib is predominantly metabolized by CYP3A4. Strong CYP3A4 inhibitors: The Cmax and AUC of ruxolitinib increased 33% and 91%, respectively, with Jakafi administration (10 mg single dose) following ketoconazole 200 mg twice daily for four days, compared to receiving Jakafi alone in healthy subjects. The half-life was also prolonged from 3.7 to 6.0 hours with concurrent use of ketoconazole. The change in the pharmacodynamic marker, pSTAT3 inhibition, was consistent with the corresponding ruxolitinib AUC following concurrent administration with ketoconazole. When administering Jakafi with strong CYP3A4 inhibitors a dose reduction is recommended [see Dosage and Administration (2.7) in Full Prescribing Information]. Patients should be closely monitored and the dose titrated based on safety and efficacy. Mild or moderate CYP3A4 inhibitors: There was an 8% and 27% increase in the Cmax and AUC of ruxolitinib, respectively, with Jakafi administration (10 mg single dose) following erythromycin, a moderate CYP3A4 inhibitor, at 500 mg twice daily for 4 days, compared to receiving Jakafi alone in healthy subjects. The change in the pharmacodynamic marker, pSTAT3 inhibition was consistent with the corresponding exposure information. No dose adjustment is recommended when Jakafi is coadministered with mild or moderate CYP3A4 inhibitors (eg, erythromycin). CYP3A4 inducers: The Cmax and AUC of ruxolitinib decreased 32% and 61%, respectively, with Jakafi administration (50 mg single dose) following rifampin 600 mg once daily for 10 days, compared to receiving Jakafi alone in healthy subjects. In addition, the relative exposure to ruxolitinib’s active metabolites increased approximately 100%. This increase may partially explain the reported disproportionate 10% reduction in the pharmacodynamic marker pSTAT3 inhibition. No dose adjustment is recommended when Jakafi is coadministered with a CYP3A4 inducer. Patients should be closely monitored and the dose titrated based on safety and efficacy. USE IN SPECIFIC POPULATIONS Pregnancy Pregnancy Category C: There are no adequate and well-controlled studies of Jakafi in pregnant women. In embryofetal toxicity studies, treatment with ruxolitinib resulted in an increase in late resorptions and reduced fetal weights at maternally toxic doses. Jakafi should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. Ruxolitinib was administered orally to pregnant rats or rabbits during the period of organogenesis, at doses of 15, 30 or 60 mg/kg/day in rats and 10, 30 or 60 mg/kg/day in rabbits. There was no evidence of teratogenicity. However, decreases of approximately 9% in fetal weights were noted in rats at the highest and maternally toxic dose of 60 mg/kg/day. This dose results in an exposure (AUC) that is approximately 2 times the clinical exposure at the maximum recommended dose of 25 mg twice daily. In rabbits, lower fetal weights of approximately 8% and increased late resorptions were noted at the highest and maternally toxic dose of 60 mg/kg/day. This dose is approximately 7% the clinical exposure at the maximum recommended dose. In a pre- and post-natal development study in rats, pregnant animals were dosed with ruxolitinib from implantation through lactation at doses up to 30 mg/kg/day. There were no drug-related adverse findings in pups for fertility indices or for maternal or embryofetal survival, growth and development parameters at the highest dose evaluated (34% the clinical exposure at the maximum recommended dose of 25 mg twice daily). Nursing Mothers It is not known whether ruxolitinib is excreted in human milk. Ruxolitinib and/or its metabolites were excreted in the milk of lactating rats with a concentration that was 13-fold the maternal plasma. Because many drugs are excreted in human milk and because of the potential for serious adverse reactions in nursing infants from Jakafi, a decision should be made to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother. Pediatric Use The safety and effectiveness of Jakafi in pediatric patients have not been established. Geriatric Use Of the total number of myelofibrosis patients in clinical studies with Jakafi, 51.9% were 65 years of age and older. No overall differences in safety or effectiveness of Jakafi were observed between these patients and younger patients. Renal Impairment The safety and pharmacokinetics of single dose Jakafi (25 mg) were evaluated in a study in healthy subjects [CrCl 72-164 mL/min (N=8)] and in subjects with mild [CrCl 53-83 mL/min (N=8)], moderate [CrCl 38-57 mL/min (N=8)], or severe renal impairment [CrCl 15-51 mL/min (N=8)]. Eight (8) additional subjects with end stage renal disease requiring hemodialysis were also enrolled. The pharmacokinetics of ruxolitinib was similar in subjects with various degrees of renal impairment and in those with normal renal function. However, plasma AUC values of ruxolitinib metabolites increased with increasing severity of renal impairment. This was most marked in the subjects with end stage renal disease requiring hemodialysis. The change in the pharmacodynamic marker, pSTAT3 inhibition, was consistent with the corresponding increase in metabolite exposure. Ruxolitinib is not removed by dialysis; however, the removal of some active metabolites by dialysis cannot be ruled out. When administering Jakafi to patients with moderate (CrCl 30-59 mL/min) or severe renal impairment (CrCl 15-29 mL/min) with a platelet count between 100 X 109/L and 150 X 109/L and patients with end stage renal disease on dialysis a dose reduction is recommended [see Dosage and Administration (2.8) in Full Prescribing Information]. Hepatic Impairment The safety and pharmacokinetics of single dose Jakafi (25 mg) were evaluated in a study in healthy subjects (N=8) and in subjects with mild [Child-Pugh A (N=8)], moderate [Child-Pugh B (N=8)], or severe hepatic impairment [Child-Pugh C (N=8)]. The mean AUC for ruxolitinib was increased by 87%, 28% and 65%, respectively, in patients with mild, moderate and severe hepatic impairment compared to patients with normal hepatic function. The terminal elimination half-life was prolonged in patients with hepatic impairment compared to healthy controls (4.1-5.0 hours versus 2.8 hours). The change in the pharmacodynamic marker, pSTAT3 inhibition, was consistent with the corresponding increase in ruxolitinib exposure except in the severe (Child-Pugh C) hepatic impairment cohort where the pharmacodynamic activity was more prolonged in some subjects than expected based on plasma concentrations of ruxolitinib. When administering Jakafi to patients with any degree of hepatic impairment and with a platelet count between 100 X 109/L and 150 X 109/L, a dose reduction is recommended [see Dosage and Administration (2.8) in Full Prescribing Information].

FDA Update Targeted Therapy

FDA Hears Proposals on Codevelopment of Companion Diagnostics for Breakthrough Therapies By Caroline McNeil

A

companion diagnostic developed for use with a drug that has received Breakthrough Therapy designation from the U.S. Food and Drug Administration (FDA) should automatically be eligible for priority review, according to an expert panel that presented this proposal and four others to the FDA in early September (see sidebar). With members representing cancer centers, industry, and the National Cancer Institute, the panel presented a report suggesting ways to modify FDA’s standard review procedures specifically for in vitro diagnostics associated with Breakthrough Therapies, the FDA’s newest pathway for expedited approval.

A major issue in the field is now codevelopment of a drug and its companion diagnostic to ensure that they can be evaluated and cleared for use in the clinic at the same time. Codevelopment is “probably the biggest development in the in vitro diagnostics world in the past few years,” said FDA’s Elizabeth Mansfield, PhD, Director of the Personalized Medicine Staff at the Center for Devices and Ra-

Dr. Mansfield said that she believed this administrative section of the proposal would be “relatively easy to do.” The Breakthrough Therapy designation was not accompanied by recommendations on the diagnostic side, she said, “but we do have processes” related to codevelopment. She added that a draft guidance on codevelopment— for companion diagnostics associated with any targeted drug, not only those

Codevelopment is probably the biggest development in the in vitro diagnostics world in the past few years. —Elizabeth Mansfield, PhD

Burgeoning Field The five proposals and FDA’s consideration of them are among the latest developments in the burgeoning field of companion diagnostics, the tests designed to show whether a patient can benefit from a specific targeted therapy. Companion diagnostics have come to the fore, especially in oncology, with the increasing number of molecular targeted therapies. In the 12 months following Congressional approval of the Breakthrough Therapy designation in July 2012, the FDA received 82 applications for the designation, most of them for targeted drugs.

diological Health. Responding to the five proposals at a public forum in September, convened by Friends of Cancer Research, she said “we know the questions. We don’t have all the answers.”

Key Recommendation First and foremost, the panel recommended that a companion diagnostic be closely linked to its associated Breakthrough Therapy, making it automatically eligible for priority review and, importantly, receiving the same intensive guidance from FDA’s senior management.

Five Proposals for the FDA

A

t a forum convened by Friends of Cancer Research in September 2013, a panel of experts presented five proposals outlining how sponsors and FDA may be able to improve and expedite the process for the codevelopment and review of a companion diagnostic designed for use with a drug that has received the FDA’s Breakthrough Therapy designation. The proposals included: 1. Automatic designation of in vitro companion diagnostic devices for use as part of a Breakthrough Therapy drug approval as eligible for priority review 2. Use of highly coordinated administrative processes and management commitments for the review of in vitro companion diagnostics associated with Breakthrough Therapies that are commensurate with those processes offered for Breakthrough Therapies 3. Use of risk-based processes to determine required analytic studies for each assay at time of premarket approval filing 4. Use of risk-based approaches to determine requirements for data and testing related to quality systems, manufacturing processes, and software testing and documentation 5. Use of a Continued Access investigational device exception supplement to enable a broader set of laboratories to be ready for testing immediately upon contemporaneous approval of the companion diagnostic and therapeutic product. n

with the breakthrough designation— will be published soon. Mike Pacanowski, PharmD, FDA’s Associate Director for Genomics and Targeted Therapy, Office of Clinical Pharmacology, noted that timing is key to successful codevelopment. The biggest issue, he said, is early development of biomarkers by sponsors so that they can be reviewed along with the Breakthrough Therapy. “When developed later, it takes more planning to accommodate them,” he said.

Analysis and Production Issues The panel’s third and fourth proposals outlined modifications to the usual FDA requirements for analytic studies and for quality systems and manufacturing processes and software. On the analytic side, for instance, one current requirement is that full specificity studies be included in the premarket approval. The recommendation is that FDA consider limiting the number of substances to be tested for cross-reactivity, endogenous interferences, effect of pharmaceuticals, or a human anti-mouse antibody (HAMA) effect (for immunoassays only). Consideration would be based on risk, on a case-by-case basis. The sponsor would present data to justify modifications during presubmission discussions, supplying the agency with a study plan for the specificity studies, any reduced requirements, and any mitigations. On the production side, one pro-

posed modification would allow an abbreviated description of a manufacturing system in place of a full description, based on whether the sponsor had an approved or pending premarket approval that contained the same or highly similar information. Similarly, instead of a full description of quality systems, the FDA could consider an abbreviated description if the sponsor had an approved or pending premarket approval that contained essentially the same information, according to another proposed modification. In general, Dr. Mansfield said, these risk-based modifications are reasonable. “Choosing what data can wait makes sense,” she said. However, she added that it may be difficult to implement the proposals related to quality systems—procedures to ensure that the process of manufacturing a diagnostic test, when repeated, results in the same response. “The biggest challenge is not from the analysis and review sides but from quality systems,” she said. “That’s the biggest hurdle.”

Investigational Device Exception The fifth proposal would allow additional laboratories, not part of the clinical trial, to conduct testing immediately upon approval of the companion diagnostic, rather than waiting several weeks for verification and approval as under current regulations. This would be done through a Continued Access investigational device exception supplement. Currently a diagnostic can be shipped at any time to other laboratories, but cannot be used except for validation purposes until FDA approval is received. Dr. Mansfield said the agency has been considering an investigational device exception supplement. “We have struggled with this,” she said, “but it is not solidified yet; we’re hoping to be able to do it.” Asked whether any of the five proposals might need legislation to implement, both FDA officials said probably not. “I think there’s a lot we can do with our current authority,” said Dr. Mansfield. “We’re looking at whether we could take it further with legislation.” n Disclosure: Dr. Mansfield reported no potential conflicts of interest.

Patient’s Corner

Having Bladder Cancer Has Taught Me Important Life Lessons Before my diagnosis, I was used to being in control and independent. Now, I value having the support of family, friends, and a caring medical team. By Fred Wright, as told to Jo Cavallo

I

think one of the most frightening— and embarrassing—things that can happen to an adult is losing control of your bladder and wetting the bed. When that happened to me in the spring of 2012 while I was on a camping trip with my wife Kimberly and our two teenage daughters, I knew something was very wrong and immediately sought medical attention. In my mid50s at the time, I had been diagnosed with an enlarged prostate and I was having some difficulty urinating, but losing control like that was alarming.

After a second opinion confirmed my surgeon’s recommendation, I had to think long and hard about what to do. Because I was still so young, I wanted to do everything in my power to save my bladder and not have my anatomy altered. But I also wanted to live and

Despite the physical and mental trauma of having cancer, I feel that my experience has been positive. I’ve learned so much about myself, and I’m now a more open person, as well as a better husband, father, and friend.

Surprising Biopsy Result A CT scan showed that I had a 7-cm tumor on my bladder situated in front of my left kidney. A cystoscopy later confirmed that the tumor was malignant. Because the tumor was so large, it was surprising when the initial biopsy report showed that the cancer was stage I. When subsequent biopsies confirmed the staging, I was faced with a difficult choice. My surgeon was convinced that the position and size of the tumor were good indicators that the cancer had, in fact, spread, and he wanted to treat me for invasive bladder cancer rather than early-stage cancer.

Giving Back To show my appreciation for all the support I received from family, friends, and a wonderful medical team—including my oncologist, who was forthright and consoling throughout my diagnosis and treatment—I’ve dedicated myself to giving back to the cancer community. I speak before groups of cancer survivors and share with them five lessons I’ve learned after having cancer. They include the importance of confronting your fears, accepting emotional support, building a strong medical team, setting priorities, and being comfortable with your decisions. Despite the physical and mental trauma of having cancer, I feel that my experience has been positive. I’ve learned so much about myself, and I’m now a more open person, as well as a better husband, father, and friend. I appreciate every day and don’t fear the future—and that’s perhaps the greatest lesson of all. n Fred Wright lives in Leesburg, Virginia.

Omega-3 Common Name: Polyunsaturated fatty acids (PUFAs) Brand Names: Omegaven, Max-EPA

T

he use of dietary supplements by patients with cancer has increased significantly over the past 2 decades despite insufficient evidence of safety and effectiveness. Finding reliable sources of information about dietary supplements can be daunting. Patients typically rely on family, friends, and the Internet, often receiving misleading information. The ASCO Post’s Integrative Oncology series is intended to facilitate the availability of evidence-based information on integrative and complementary therapies commonly used by patients with cancer. We chose omega-3 fatty acids for this issue because of their growing use by cancer patients.

Integrative Oncology is compiled by Barrie R. Cassileth, MS, PhD, and Jyothirmai Gubili, MS, Memorial SloanKettering Cancer Center. The free About Herbs website is managed by K. Simon Yeung, PharmD, LAc, Memorial SloanKettering Cancer Center.

Overview

Omega-3 fatty acids are polyunsaturated fatty acids that play a crucial

role in many physiologic processes. Because our bodies cannot synthesize them, omega-3s must be obtained through diet or dietary supplements. Good sources of omega-3 include fatty fish, some plants, and nut oils. The three most studied omega-3s are alpha-linolenic acid, eicosapentanoic acid, and docosahexanoic acid. These are also the form most commonly used in dietary supplements. Following consumption, alpha-linolenic acid is converted to eicosapentanoic acid and docosahexanoic acid, forms that are readily used by the body. The current U.S. Food and Drug Administration recommendation is to limit intake of eicosapentanoic acid and docosahexanoic acid to 3 g/d (due to a potential risk of excessive bleeding in some individuals at higher intakes). Available data strongly support the protective effects of omega-3s against cardiovascular disease. Benefits have been reported also for a wide range of conditions, including depression, inflammatory bowel disease, and autoimmune disorders such as rheumatoid arthritis and systemic lupus erythematosus. Omega-3s may play a role in cancer prevention, but definitive data are ­lacking.

The Science

A large survey of Finnish adults found that depressive symptoms were significantly higher among infrequent fish consumers.1 Supplementation with docosahexanoic acid improved learning and memory function in age-

elderly subjects4 remain inconclusive. Omega-3 supplements lowered cholesterol levels in individuals with

hypercholesterolemia,5 and reduced recurrence in patients with history of stroke.6 In another study of patients with rheumatoid arthritis, omega-3 supplementation reduced nonsteroidal anti-inflammatory drug use.7 Fish oil also was shown to relieve symptoms associated with systemic lupus erythematosus.8 Findings of a systematic review support beneficial effects of omega-3 consumption on insulin sensitivity and adipocyte function.9 Omega-3s may reduce colon cancer risk10 and improve immune response in patients undergoing colorectal cancer resection,11 but they did not affect cancer outcomes.12 Similarly, studies of fish oil supplements suggest that they reduce the risk of breast cancer,13 but data from the Se-

Integrative Oncology lenium and Vitamin E Cancer Prevention Trial (SELECT) found increased risk of prostate cancer in patients with high blood levels of omega‑3.14 Further research is needed to determine the likely specific cancer preventive potential of omega-3s. Preliminary findings from recent studies suggest that fish oil supplementation increases the efficacy of chemotherapy, improves survival,15 and helps maintain weight and muscle mass16 in patients with non–small cell lung cancer (NSCLC). Further, an eicosapentanoic acid–enriched oral supplement improved the tolerability of chemotherapy in patients with advanced colorectal cancer.17

Adverse Effects

Fishy aftertaste,10 loose stools, and nausea18 were reported after consuming large doses of omega-3 fatty acids.

Herb-Drug Interactions

Nonsteroidal anti-inflammatory drugs: Fish oil can have additive anticoagulant/antiplatelet effects,19 but a recent study reported that omega-3s do not affect coagulation or platelet function postsurgery.20

Lab Interactions

Omega-3s may reduce levels of alpha-tocopherol and beta-carotene.10,21 High levels of omega-3s may decrease triglycerides, and increase lowdensity lipoprotein cholesterol levels.22 Doses higher than 3 g/d may increase bleeding time.23 n

Disclosure: Ms. Gubili reported no potential conflicts of interest.

OF NOTE The role of omega-3s in cancer prevention awaits further investigation. Oncologists should be aware of their potential to interact with anticoagulant medications. References 1.

Attempting to Elude Fate One woman is Annie Parker, played by Samantha Morton, whose mother was diagnosed with breast cancer when she was pregnant with Annie and died of the disease when Annie was 13. In 1978, when Annie’s older sister Joan and first cousin also die of breast cancer, she is convinced that the disease is coming for her too. Two years later, at age 29, it does. Told by doctors that it was just “bad luck” that so many immediate family members died of breast cancer, Annie instinctively knows that there has to be an inherited cause and not random chance that doomed the women in her family to cancer and an early death. And she is desperate to avoid their fate. After undergoing a mastectomy of her left breast, followed by grueling regimens of chemotherapy that leave her bald, sick, and exhausted from vomiting, Annie grills her doctors about the possibility of breast cancer being an inherited disease and pours

With a clock in her office marked off every 12 minutes by pink tape to signify how often a woman dies of breast cancer, Dr. King had been researching a potential genetic link to the disease since the mid-1970s. When the film begins, Dr. King has compiled data on about 80 women with a family history of breast cancer. Because it could take a decade or more to sequence gene mutations using the only available computer technology at the time—a primitive 2.5ton mainframe computer—it took Dr. King until 1990 to finally discover that a single gene on chromosome 17q21, which she named BRCA1, was

Decoding Annie Parker is an inspiring film that gives testament to the courage and perseverance of patients with cancer and showcases the determination of scientists to identify the causes of the disease.

Raising Money for Breast Cancer Research Although the film is scheduled for commercial release early in 2014, Decoding Annie Parker has been shown at film festivals and charity events around the country since the spring, to raise awareness of breast cancer and funds for research. In October, the Hamptons International Film Festival and The Sloan Foundation awarded director Steven Bernstein the $25,000 Alfred P. Sloan Feature Film Prize, which encourages the creation of more realistic and accurate films about science and technology. Decoding Annie Parker stars Samantha Morton (Annie Parker), Helen Hunt (Dr. Mary-Claire King), Aaron Paul (Paul, Annie’s husband), Marley Shelton ( Joan, Annie’s sister), Rashida Jones (Kim), and Bradley Whitford (Marshall, Annie’s second husband). n

‘Clear and Consistent Protective Effect of Marriage’ Found in Patients With 10 Most Clinically Significant Cancers By Charlotte Bath

“A

clear and consistent protective effect of marriage among patients harboring one of the 10 most clinically significant malignancies affecting Americans” was found in a study analyzing Surveillance, Epidemiology, and End Results

“We were very surprised by this. We certainly suspected that marriage had some kind of beneficial effect, but we didn’t realize it would be this big. That really speaks to the importance of social support in the care of patients with can-

That [beneficial effect of marriage] really speaks to the importance of social support in the care of patients with cancer. —Paul L. Nguyen, MD

(SEE) data for 734,889 patients diagnosed with lung, colorectal, breast, pancreatic, prostate, liver/intrahepatic bile duct, head/neck, ovarian, or esophageal cancer, or non-Hodgkin lymphoma. “For five cancers studied (prostate, breast, colorectal, esophageal, and head/neck cancers), the survival benefit associated with marriage was larger than the published survival benefit of chemotherapy,” noted the study authors.1

cer,” the study’s corresponding author, Paul L. Nguyen, MD, told The ASCO Post in a joint interview with lead author Ayal A. Aizer, MD, MHS. “We definitely recognize that chemotherapy is important, but so is making sure that patients actually follow through and get access to therapies and the social support that they need to make it through these kinds of therapies,” Dr. Nguyen said. He is Director of Prostate Brachytherapy

at Dana-Farber/Brigham and Women’s Cancer Center and Assistant Professor of Radiation Oncology at Harvard Medical School in Boston. Dr. Aizer is Chief Resident of the Harvard Radiation Oncology Program. The study was published in the Journal of Clinical Oncology1 and widely reported by the major media, including The New York Times, USA Today, the Cleveland Plain Dealer, CNN, and NBC Nightly News. “We don’t ultimately know with 100% certainty what marriage is doing for patients, but our suspicion—and we have some data to support this—is that it is to provide support for patients with cancer,” Dr. Aizer said. “I think most of the media outlets have picked up on that, and I think that they have represented the study well.”

Less Likely to Die as Result of Cancer “Married patients were less likely to present with metastatic disease (adjusted odds ratio [OR] = 0.83, 95% confidence interval [CI] = 0.82–0.84, P < .001), more likely to receive definitive therapy (adjusted OR = 1.53, 95% CI = 1.51–1.56; P < .001), and less likely to die as a result of their cancer after adjusting for demo-

graphics, stage, and treatment (adjusted hazard ratio = 0.80, 95% CI = 0.79–0.81, P < .001) than unmarried patients,” according to the study report. “These associations remained significant when each individual cancer was analyzed (P < .05 for all endpoints for each malignancy). The benefit associated with marriage was greater in males than females for all outcome measures analyzed (P < .001 in all cases).” Longer follow-up is needed to determine median overall survival. Being married may contribute to improved outcomes because spouses may encourage their counterparts to seek medical attention for worrisome symptoms and to undergo definitive treatments. “There are many explanations for the vital question of why marriage is associated with improved cancerspecific survival after adjustment for demographics, stage, and treatment, but the most likely reason is that married patients have better adherence with prescribed treatments than unmarried patients,” the researchers reported.

Particularly Important for Head and Neck Cancers Just making sure patients get to treatment is important. “We’ve looked

he study finding that unmarried patients with cancer “are at significantly higher risk of presentation with metastatic cancer, undertreatment, and death resulting from their cancer,” generated a lot of comments from colleagues, family members, and patients, the study’s lead author Ayal A. Aizer, MD, MHS, told The ASCO Post. “We’ve had patients we’ve never even met before calling us from different parts of the country because they heard about the study and they have insights that they want to offer. Several patients contacted me and wanted to highlight the message about depression,” Dr. Aizer added. “They thought that their mental status was improved by a spouse, which really got them through the treatment. They felt that just having someone to talk with and share the burden gave them the motivation to get through the treatment, to have something to fight for, something to live for.”

Rallying Support Physicians can capitalize on the interest in the report to stress the importance of good support systems for patients with cancer and their

families. “Anything patients can really be doing to get the support that they need is good. That could mean reaching out to families or friends,

from your friend, your neighbor, somebody who knows and cares about you,” Paul L. Nguyen, MD, added. “We want to empower every-

body who has a friend or a loved one with cancer to go to the doctor with their friend and be there for him.” Dr. Nguyen is Director of Prostate Brachytherapy at Dana-Farber/ Brigham and Women’s Cancer Center in Boston and Assistant Professor of Radiation Oncology at Harvard Medical School. Dr. Aizer, MD, is Chief Resident of the Harvard Radiation Oncology Program. “What we really want people to start thinking and talking about is that unmarried patients with cancer seem to do more poorly after their diagnosis,” Dr. Aizer said. “This is something that we need to be thinking about as doctors. We should be asking our patients about the support they have if they are not married, and frankly, if they are married, too, and think about ways to get them better supported if it looks like these support systems are lacking for them.” n

at several cancers where that is particularly important, and the one that jumps out at us is head and neck cancer. For this disease, patients have to come in for radiation treatment every day, usually for about 7 weeks, and it is not an easy treatment to tolerate…. So that physical element of having someone not only help manage the side effects, but also get the patient to the doctor on a day-to-day basis, which we know is so important, may be making a difference,” Dr. Aizer said. “In our clinic for head and neck patients at Dana-Farber, when you meet with your physician, it is in a multidisciplinary setting. Not only is there a surgeon, a medical oncologist, and a radiation oncologist, but there is a social worker who is part of the team, who is always thinking about the social situation of the patient and what kind of social support they may might need,” Dr. Nguyen said. “The social worker can set up rides for you to get to your treatment, can help you with the logistics so that you can show up every day. We don’t have that in treatment for all disease sites, but in head and neck, it is such an important thing to show up every day for your treatment,” he added.

Sharing the Emotional Burden “Having someone to share the emotional burden of the diagnosis and cope with everything that is going on” is also important, Dr. Aizer said. “Physicians should consider screening for depression among unmarried persons and refer patients to mental health specialists if needed. In addi-

tion, physicians should consider closer observation of unmarried patients with cancer to maximize adherence,” the study report advises. “We know that people who are married in general show lower rates of depression and that patients who are depressed after diagnosis of cancer tend not to adhere to the therapies that are

‘Not Just a Pat on the Back’ Both Dr. Aizer and Dr. Nguyen stressed that the findings of their study should not be construed as “just a pat on the back” for married patients. “The importance of this study is that it highlights the consistent and substantial impact that features of marriage, particularly social support, can have on cancer detection, treatment, and survival,” the study authors noted. “It raises the possibility that investments in targeted social support interventions aimed at vulnerable populations, such as unmarried patients, could significantly improve the likelihood of achieving cure.” Dr. Nguyen said, “What we see from this research is that social support really helps. If a patient is single, we might need to help that patient a little more. To me, it is not so much about whether you’re married or you’re single, but more about whether you are coming by yourself to appointments or if there is somebody there with you to support you,” he commented. “Hospitals should really be focusing on this as a way to potentially improve outcomes among their cancer populations,” Dr. Aizer stated.

and also to just keep your life in order so that you can show up every day for your treatment. That’s a lot of work, a lot that you have to juggle,” Dr. Nguyen said. “Sometimes unmarried patients with cancer may not be asking for the support that they need. They may not recognize that they really may need more physical and emotional support,” Dr. Aizer said. “We wonder if this is more of an issue with men than women—not asking for the support they may need.” Single women, he said, “may be more effective in rallying support from other sources.”

Care for the Caregiver “When we assess the patient, we should think about how the caregiver is doing,” Dr. Nguyen said. “That is something that is being taught at a

lot more medical schools and in residencies—to really look at the caregiver, who this person’s supports are, and spend some time thinking about them and how they fit into the entire care team as well. To a certain degree, this borrows from the pediatric literature, where in the pediatric setting you are not just the patient’s doctor, but also the parents’ doctor. We are starting to incorporate that kind of thinking into a lot more disease sites, although not necessarily in a formal way,” he added. “Cancer centers would do well to screen for the at-risk family,” noted an accompanying editorial by David W. Kissane, MD, of Monash University, Victoria, Australia, and Memorial Sloan-Kettering Cancer Center and Weill Cornell Medical College, New York.2 “The provision of family-focused therapy ought to be a routine outpatient service for couples and families in modern cancer.”

Unmarried Subgroups In the study, marital status was classified as either married on unmarried and then reanalyzed as married vs single, separated, divorced, or widowed. “When we looked at different types of unmarried patients, we didn’t find any differences among them in terms of how well they did after the diagnosis of cancer, be it what stage they presented at with their cancer, whether they got the treatment that they should receive, and most importantly, did they survive their cancer. The fact that the widowed population—who were once married—did just as poorly as some of the other unmarried groups seems to indicate that there really is something about what marriage is providing, rather than some innate characteristic of people who get married, that is driving the results in our studies,” Dr. Aizer remarked. It is not known how many people in the unmarried category in the study

were in relationships. “They may be dating someone, they may be engaged, they may be in a same-gender relationship in a state where marriage is not recognized,” Dr. Aizer noted, but “those patients would be characterized as unmarried in our study, given the database we used. The fact that all unmarried patients were put together in the same cohort, whether they were in relationships or not, tells us that the differences we saw may be even greater than what we appreciated.” n

The Power of Human Attachment By David Kissane, MD

F

or those patients with cancer who may be single, widowed, separated, or divorced, those for whom a natural social support system may be weak, the role of the cancer support group should not be overlooked. In leading a previous trial of supportive-expressive group therapy as a key pathway to foster social support, I found that patients who successfully connected with a cancer support group felt better supported and were more adherent with conventional anticancer therapy than those who did not.1

Major Debate One conundrum not addressed in this article for The ASCO Post is why three earlier randomized controlled trials of supportive-expressive group therapy failed to extend survival.1-3 The question arises that if being married extends survival, which it clearly does, shouldn’t other forms of support also help in extending survival? This Dr. Kissane is a Recent Chairman of the Department of Psychiatry & Behavioral Sciences at Memorial Sloan-Kettering Cancer Center (2003-2012); Adjunct Professor of Psychiatry at Weill Cornell Medical College.

has been a major debate in oncology. In my editorial that accompanied the paper by Aizen et al,4,5 I suggested that the sample sizes in these group therapy studies were too small, that the cohorts should have targeted unmarried women, and that group sup-

its treated members compared to those receiving usual oncology care.1 Improving treatment adherence and preventing depression are such important goals of psycho-oncology. To achieve these goals, however, institutions need to open up staffing to

port remains vital in cancer care, with the Aizen et al article stressing the importance of social support. The three group therapy trials had many married participants, which might have caused them to fail to show a survival benefit through a “ceiling effect.” That is, so many were well supported by already being married that the margin of gain for those who were single was masked. Further, our supportive-expressive group therapy trial prevented the development of depression among

Conclusions The study by Aizer et al verifies the power of human attachment. It shows a relationship between marriage status and cancer survival, and perhaps serves as an important reminder to clinicians that a patient’s single status may be a red flag for poor social support. In such cases, referral to psychooncology services may be warranted.

Clinicians ought to be reminded of the importance of that 16th century axiom, “To cure sometimes, to relieve often, to comfort always (Anonymous).” Targeted supportive programs are necessary to attend to those individuals most in need of social support and an opportunity for better quality of life and improved survival. n

Emerging Clinical Data on Cancer Management BREAST CANCER Variations in Risk Factors Suggest Distinct Etiology for Inflammatory Breast Cancer “Varying risk factor associations between inflammatory and noninflammatory breast cancer suggest a distinct etiology for [inflammatory] breast cancer,” according to a study in the Journal of the National Cancer Institute. High body mass index was shown to increase risk of inflammatory breast cancer “irrespective of menopausal status and estrogen receptor (ER) expression,” the researchers reported. The study included 617 inflammatory breast cancer case subjects in a nested case–control study from the Breast Cancer Surveillance Consortium database (1994–2009), reported Catherine Schairer, PhD, of the National Cancer Institute, and colleagues. “We also included 1,151 noninflammatory, locally advanced, invasive breast cancers with chest wall/breast skin involvement, 7,600 noninflammatory invasive case subjects without chest wall/breast skin involvement, and 93,654 control subjects matched to case subjects on age and year at diagnosis, and mammography registry.” “The average age of diagnosis for [inflammatory breast cancer] case subjects was 4 years younger than for [noninflammatory disease] case subjects,” the authors noted. Risk factor associations with family

history of breast cancer and mammographic breast density were similar for all groups. Besides high body mass index, other risk factor variations were later age at first birth (which was associated with a reduced risk of ER-negative inflammatory breast cancer greater than for ER-negative noninflammatory disease) and education level. A higher level of education was “associated with reduced risk of ER-positive [inflammatory breast cancer], more so than for noninflammatory breast cancer,” the investigators reported. “Notably, overweight and obesity statuses were associated with increased [inflammatory breast cancer] risk regardless of the internal hormonal milieu or the ER status of the tumors,” the researchers commented. They found that among patients with inflammatory breast cancer, the “rate ratios for [body mass index of] 30 and greater vs [body mass index] less than 25 were 3.90 (95% CI = 1.50–10.14) in premenopausal women and 3.70 (95% CI = 1.98–6.94) in peri/postmenopausal women not currently using hormones.”

Accompanying Commentary According to an editorial accompanying the article, “These findings show conclusively that obesity is a strong risk factor for [inflammatory breast cancer], and they are in stark contrast with the far lower rate ratios for the association of obesity with other breast cancer types, which ranged

from 1.02 to 1.36. This finding supports the idea that [inflammatory breast cancer] is a distinct epidemiologic entity, in addition to being a distinct clinicopathologic entity,” wrote the editorialists. “Understanding the mechanism by which obesity contributes to the risk of breast cancer is important and may lead to identification of some biologic targets. However, the greatest need is to modify behavior and stop the obesity epidemic in the first place,” they concluded. Schairer C, et al: J Natl Cancer Inst 105:1373-1384, 2013. Amiri-Kordestani L, et al: J Natl Cancer Inst 105:1340-1342, 2013.

Impact of Hormone Replacement Therapy on Breast Cancer Risk Varies by Race, Weight, and Breast Density The impact of hormone replacement therapy on breast cancer risk varies according to the patient’s to race/ethnicity, body mass index, and breast density. An analysis of 1,642,824 screening mammograms with 9,300 breast cancer cases in postmenopausal women aged 45 years or older found that hormone replacement therapy was more strongly associated with breast cancer in leaner women with dense breasts. “Black women, obese women, and women with breast tissue composed largely of fat may benefit from [hormone replacement therapy] use with minimal excess breast cancer risk,” Ningqi Hou, MD, PhD, of the University of Chicago, reported in the Journal of the National Cancer Institute.

Key Findings

Data for the study was from the Breast Cancer Surveillance Consortium, a longitudinal registry of mammography screening in the United States, and “multiple imputation methods were used to accommodate missing data for [hormone replacement therapy] use (14%) and other covariables,” the researchers reported. Use of hormone replacement therapy was associated with more than a 20% increased risk in white women (odds ratio [OR] = 1.21; 95% CI = 1.14–1.28), Asian women (OR = 1.58; 95% CI = 1.18–2.11), and Hispanic women (OR = 1.35; 95% CI = 1.09–1.67) but not black women (OR = 0.91; 95% CI = 0.72–1.14; Pinteraction = .04). “In women with low/normal [body mass index] and extremely dense breasts, [hormone replacement therapy] use was associated with the highest breast cancer risk (OR = 1.49; 95% CI = 1.21–1.83), compared with nonusers. In overweight/

obese women with less-dense breasts, no excess risk was associated with [hormone replacement therapy] use (adjusted ORs = 0.96–1.03),” the investigators wrote. About 55% of the study population had an increased risk of breast cancer due to hormone replacement therapy use, the researchers found. For the 20% of the study population that was overweight and obese with less-dense breasts, “the association between [hormone replacement therapy] use and breast cancer risk was essentially absent (adjusted ORs = 0.96–1.03). The remaining 25% of the study population had an elevated risk of breast cancer due to [hormone replacement therapy] use, but statistical significance was not reached.” The study did not include information on the type of hormone replacement therapy used and the duration of use. The authors concluded that if their findings are confirmed in other studies with more detailed information about these and other risk factors, hormone replacement therapy use “may be reasonable for some women.”

Cautious Interpretation In an accompanying editorial, Mary Beth Terry, PhD, and Parisa Tehrnifar, DrPH, of Columbia University, Mailman School of Public Health, in New York, commented, “Results from studies such as that by Hou et al that lack details of [hormone replacement therapy] use, including type and duration, should be interpreted cautiously before drawing conclusions about risk stratification by race/ethnicity…. Beyond single stratifications by [body mass index] and race, however, the Hou et al study advances the literature by examining breast density in combination with these factors. Even this large study, though, is underpowered for examining race/ethnicity interactions with both [body mass index] and breast density,” the editorialists wrote. “Ultimately, efforts that improve risk stratification, whether made through improved risk models or through measuring valid intermediate biomarkers such as breast density, will inform appropriate use of not only [hormone replacement therapy], but also other medications including chemopreventive drugs,” they added.

nect to relevant patient assistance programs receive useful informational and psychosocial but not practical help,” concluded Nina A. Bickell, MD, MPH, of Mount Sinai School of Medicine in New York, and colleagues who conducted a randomized trial among 374 women in need of adjuvant treatment after surgery for early-stage breast cancer. “Although these programs can provide patients with cancer with resources and support beyond those provided by hospitals at little to no cost to the institution, they do not affect rates of treatment,” the authors added. Recruited from eight inner city New York teaching hospitals, 190 women were randomly assigned to intervention and 184 to usual care. The average age was 56.7 years; 79% were high school graduates, and about 50% lived with a significant other. High rates of patients in both groups received treatment: 87% of intervention patients and 91% of usual care patients who underwent lumpectomy received radiotherapy (P = .39); 93% of intervention recipients and 86% of usual care recipients with estrogen receptor (ER)negative tumors ≥ 1 cm received chemotherapy (P = .42); 92% of the intervention group and 93% of the usual care group with ER-positive tumors ≥ 1 cm received hormonal therapy (P = .80).

Study Design “All patients were surveyed at baseline to measure breast cancer experiences, knowledge, attitudes, and beliefs, followed by a needs assessment,” the investigators explained. An individual action plan was created for each patient to enable contact with identified high-quality assistance programs, and at follow-up 2 weeks later, intervention patients were asked whether they had contacted the programs specified in their action plan. If not, they were asked if they still needed help, and those with unmet needs were assigned to an outreach worker. Usual care patients were mailed a New York State Department of Health pamphlet about breast cancer that included resource contact information and were called to confirm they received it. “High rates of [intervention] patients with needs connected with a program within 2 weeks (92%),” the authors reported. At 6 months, both groups used patient-assistance programs at similar rates (75% vs 76%, P = .54). The intervention did not result in more women connecting with programs or receiving treatment. A majority of women (288 [77%]) reported at least one need; 143 were

randomly assigned to intervention, and 145 to usual care. Many had multiple needs, with 63% reporting informational; 55%, psychosocial; and 53%, practical needs, such as paying for and getting to and from treatment. “Women with informational or psychosocial needs were more likely to re-

ceive help” (relative risk [RR] = 1.77, 95% CI = 1.51–1.90; and RR = 1.37; 95% CI = 1.06–1.61, respectively), the researchers reported. While 76% reported receiving specific help from the programs, only 7% of women in the intervention group and 4% in the usual care group with practical needs reported receiving help from a program.

ASCO’s 2013 Top Five List in Oncology for Choosing Wisely Campaign

A

SCO recognizes the importance of evidence-based cancer care and making wise choices in the diagnosis and management of patients with cancer. After careful consideration by experienced oncologists, ASCO annually highlights five categories of tests, procedures and/or treatments annually whose common use and clinical value are not supported by available evidence as part of the American Board of Internal Medicine’s (ABIM) Choosing Wisely® Campaign.

Antiemetic Drugs Do not give patients starting on a chemotherapy regimen that has a low or moderate risk of causing nausea and vomiting anti-emetic drugs intended for use with a regimen that has a high risk of causing nausea and vomiting. Over the past several years, a large number of effective drugs with fewer side effects have been developed to prevent nausea and vomiting from chemotherapy. When successful, these medications can help patients avoid spending time in the hospital, improve their quality of life, and lead to fewer changes in the chemotherapy regimen. Oncologists customarily use different antiemetic drugs depending on the likelihood (low, moderate, or high) for a particular chemotherapy program to cause nausea and vomiting. For chemotherapy programs that are likely to produce severe and persistent nausea and vomiting, there are new agents that can prevent this unfortunate side effect. However, these drugs are very expensive and not devoid of side effects. For this reason, these drugs should be used only with the chemotherapy drugs that have a high likelihood of causing severe or persistent nausea and vomiting. When using chemotherapy that is less likely to cause nausea and vomiting, there are other effective drugs available at a lower cost.

Combination Chemotherapy Do not use combination chemotherapy (multiple drugs) instead of chemotherapy with one drug when treating an individual for metastatic breast cancer unless the patient needs a rapid response to relieve tumor-related symptoms. Although chemotherapy with multiple drugs, or combination chemotherapy, for metastatic breast cancer may slow tumor growth for a somewhat longer time than occurs when treating with a single agent, use of combination chemotherapy has not been shown to increase overall survival. In fact, the trade-offs of more frequent and severe side effects may have a net effect of worsening a patient’s quality of life, necessitating a reduction in the dose of chemotherapy. Combination chemotherapy may be useful and worth the risk of more side effects in situations in which the cancer burden must be reduced quickly because it is causing significant symptoms or is life threatening. As a general rule, however, giving effective drugs one at a time lowers the risk of side effects, may improve a patient’s quality of life, and does not typically compromise overall survival.

Imaging Avoid using PET or PET-CT scanning as part of routine followup care to monitor for a cancer recurrence in asymptomatic patients who have finished initial treatment to eliminate the cancer unless there is high-level evidence that such imaging will change the outcome. PET and PET-CT are used to diagnose, stage, and monitor how well treatment is working. Available evidence from clinical studies suggests that using these tests to monitor for recurrence does not improve outcomes and therefore generally is not recommended for this purpose. False positive tests can lead to unnecessary and invasive procedures,

overtreatment, unnecessary radiation exposure, and incorrect diagnoses. Until high-level evidence demonstrates that routine surveillance with PET or PET-CT scans helps prolong life or promote well-being after treatment for a specific type of cancer, this practice should not be done.

PSA Testing Do not perform PSA testing for prostate cancer screening in men with no symptoms of the disease when they are expected to live less than 10 years. Since PSA levels in the blood have been linked with prostate cancer, many doctors have used repeated PSA tests in the hope of finding “early” prostate cancer in men with no symptoms of the disease. Unfortunately, PSA is not as useful for screening as many have hoped because many men with prostate cancer do not have high PSA levels, and other conditions that are not cancer (such as benign prostate hyperplasia) can also increase PSA levels. Research has shown that men who receive PSA testing are less likely to die specifically from prostate cancer. However when accounting for deaths from all causes, no lives are saved, meaning that men who receive PSA screening have not been shown to live longer than men who do not have PSA screening. Men with medical conditions that limit their life expectancy to less than 10 years are unlikely to benefit from PSA screening as their probability of dying from the underlying medical problem is greater than the chance of dying from asymptomatic prostate cancer.

Targeted Therapy and Biomarkers Do not use a targeted therapy intended for use against a specific genetic aberration unless a patient’s tumor cells have a specific biomarker that predicts an effective response to the targeted therapy.

Targeted therapy can significantly benefit people with cancer because it can target specific gene products, i.e., proteins that cancer cells use to grow and spread, while causing little or no harm to healthy cells. Patients who are most likely to benefit from targeted therapy are those who have a specific biomarker in their tumor cells that indicates the presence or absence of a specific gene alteration that makes the tumor cells susceptible to the targeted agent. Compared to chemotherapy, the cost of targeted therapy is generally higher, as these treatments are newer, more expensive to produce, and under patent protection. In addition, like all anti-cancer therapies, there are risks to using targeted agents when there is no evidence to support their use because of the potential for serious side effects or reduced effiacy compared with other treatment options. Note: These test and treatment options should not be administered unless the physician and patient have carefully considered if their use is appropriate in the individual case. As an example, when a patient is enrolled in a clinical trial, these tests, treatments, and procedures may be part of the trial protocol and therefore deemed necessary for the patient’s participation in the trial. These items are provided solely for informational purposes and are not intended to replace a medical professional’s independent judgment or as a substitute for consultation with a medical professional. Patients with any specific questions about the items on this list or their individual situation should consult their health care provider.

Choosing Wisely: Good Care With Efficiency By Richard J. Boxer, MD, FACS

I

s more care better care? It is often said, by Americans, that the United States has the best care in the world. However, there are many population-based statistics that do not support that humble opinion. We certainly spend more money than any other nation by far. In fact, we may spend more money than nearly all other countries in the world combined. This begs a number of questions: (1) Are we getting our money’s worth? (2) Are patients being overtested and overtreated? (3) Can we physicians together decide what is reasonable to discuss with our patients to avoid unnecessary treatments and tests, and yet simultaneously improve care?

has been a leader in this extraordinary pursuit of excellence and has created its own set of recommended topics for discussion and consideration. As a demonstration of the per-

ceived value of this effort, private companies have developed sets of discussion points that help guide patients at the time of tremendous stress.

Once again, and appropriately so, our physician colleagues are taking the leadership role in creating better care for our patients. It is now up to all of us to follow the guidelines. n

Skin Effects of Cancer For Your

Patients

More people than ever before are living with and surviving cancer. However, even the most promising cancer treatments may cause unexpected side effects to the skin, hair, and nails. How can your patients navigate these changes while staying on treatment and maintaining some quality of life? Written for people living with cancer by Dr. Mario Lacouture, an expert in the dermatologic side effects of anticancer medications, this book offers your patients clear information and practical suggestions for preventing, treating, and living through these skin, hair, and nail changes.

Yes We Can

• Preparation for the rash, itching, or dry skin that may come with cancer treatment

The answer to these questions is “Yes.” A program originally conceived by the National Physicians Alliance through an America Board of Internal Medicine (ABIM) Foundation Putting the Charter into Practice grant, created a set of three lists of specific steps physicians in internal medicine, family medicine, and pediatrics could take in their practices to promote the more effective use of health-care resources. These lists were first published in Archives of ­Internal Medicine.

Pursuit of Excellence Over 50 national medical organizations have created discussion points that emphasize quality of care without overtesting and overtreating.

Gastrointestinal Perforations The incidence of gastrointestinal perforation, some fatal, in Avastin‑treated patients ranges from 0.3 to 2.4%. Discontinue Avastin in patients with gastrointestinal perforation. [See Dosage and Administration (2.4), Warnings and Precautions (5.1).] Surgery and Wound Healing Complications The incidence of wound healing and surgical complications, including serious and fatal complications, is increased in Avastin‑treated patients. Discontinue Avastin in patients with wound dehiscence. The appropriate interval between termination of Avastin and subsequent elective surgery required to reduce the risks of impaired wound healing/wound dehiscence has not been determined. Discontinue at least 28 days prior to elective surgery. Do not initiate Avastin for at least 28 days after surgery and until the surgical wound is fully healed. [See Dosage and Administration (2.4), Warnings and Precautions (5.2), Adverse Reactions (6.1).] Hemorrhage Severe or fatal hemorrhage, including hemoptysis, gastrointestinal bleeding, central nervous systems (CNS) hemorrhage, epistaxis, and vaginal bleeding occurred up to five‑fold more frequently in patients receiving Avastin. Do not administer Avastin to patients with serious hemorrhage or recent hemoptysis. [See Dosage and Administration (2.4), Warnings and Precautions (5.3), Adverse Reactions (6.1).]

This approval reflects the promise of the Breakthrough Therapy designation program, allowing [FDA] to work collaboratively with companies to expedite the development, review, and availability of important new drugs.

1 INDICATIONS AND USAGE 1.1 Metastatic Colorectal Cancer (mCRC) Avastin is indicated for the first‑ or second‑line treatment of patients with metastatic carcinoma of the colon or rectum in combination with intravenous 5‑fluorouracil–based chemotherapy. Avastin, in combination with fluoropyrimidine‑irinotecan‑ or fluoropyrimidine‑ oxaliplatin‑based chemotherapy, is indicated for the second‑line treatment of patients with metastatic colorectal cancer who have progressed on a first‑line Avastin‑containing regimen. Limitation of Use: Avastin is not indicated for adjuvant treatment of colon cancer. [See Clinical Studies (14.2).]

1.3 Glioblastoma Avastin is indicated for the treatment of glioblastoma with progressive disease in adult patients following prior therapy as a single agent. The effectiveness of Avastin in glioblastoma is based on an improvement in objective response rate. There are no data demonstrating an improvement in disease‑related symptoms or increased survival with Avastin. [See Clinical Studies (14.4).]

tion to receive FDA approval. This designation was requested by the sponsor, Genentech, and granted soon after the Biologic License Application to support marketing approval was submitted to the FDA. The FDA also granted obinutuzumab priority review because the drug demonstrated the potential to be a significant improvement in safety or effectiveness in the treatment of a serious condition. And the FDA granted obinutuzumab orphan product designation because it is intended to treat a rare disease. “Today’s approval represents an important new addition to the treatments for patients with CLL,” said Richard Pazdur, MD, Director of the Office of Hematology and Oncology Products in the FDA’s Center for Drug Evaluation and Research. “This approval reflects the promise of the Breakthrough Therapy designation program, allowing us to work collaboratively with companies to expedite the develop-

to chlorambucil alone in participants with previously untreated CLL. Participants receiving obinutuzumab in combination with chlorambucil demonstrated a significant improvement in progression-free survival: an average of 23 months compared with 11.1 months with chlorambucil alone. The most common side effects observed in participants receiving obinutuzumab in combination with chlorambucil were infusion-related reactions, neutropenia, thrombocytopenia, anemia, musculoskeletal pain, and pyrexia. Obinutuzumab is being approved with a boxed warning regarding hepatitis B virus reactivation and progressive multifocal leukoencephalopathy. These are known risks with other monoclonal antibodies in this class, and rare cases were identified in participants on other trials of obinutuzumab. Patients should be advised of these risks and assessed for hepatitis B virus and reactivation risk. n

1.2 Non‑Squamous Non–Small Cell Lung Cancer (NSCLC) Avastin is indicated for the first‑line treatment of unresectable, locally advanced, recurrent or metastatic non–squamous non–small cell lung cancer in combination with carboplatin and paclitaxel.

1.4 Metastatic Renal Cell Carcinoma (mRCC) Avastin is indicated for the treatment of metastatic renal cell carcinoma in combination with interferon alfa. 4 CONTRAINDICATIONS None. 5 WARNINGS AND PRECAUTIONS 5.1 Gastrointestinal Perforations Serious and sometimes fatal gastrointestinal perforation occurs at a higher incidence in Avastin treated patients compared to controls. The incidence of gastrointestinal perforation ranged from 0.3 to 2.4% across clinical studies. [See Adverse Reactions (6.1).] The typical presentation may include abdominal pain, nausea, emesis, constipation, and fever. Perforation can be complicated by intra‑abdominal abscess and fistula formation. The majority of cases occurred within the first 50 days of initiation of Avastin. Discontinue Avastin in patients with gastrointestinal perforation. [See Boxed Warning, Dosage and Administration (2.4).] 5.2 Surgery and Wound Healing Complications Avastin impairs wound healing in animal models. [See Nonclinical Toxicology (13.2).] In clinical trials, administration of Avastin was not allowed until at least 28 days after surgery. In a controlled clinical trial, the incidence of wound healing complications, including serious and fatal complications, in patients with mCRC who underwent surgery during the course of Avastin treatment was 15% and in patients who did not receive Avastin, was 4%. [See Adverse Reactions (6.1).] Avastin should not be initiated for at least 28 days following surgery and until the surgical wound is fully healed. Discontinue Avastin in patients with wound healing complications requiring medical intervention. The appropriate interval between the last dose of Avastin and elective surgery is unknown; however, the half‑life of Avastin is estimated to be 20 days. Suspend Avastin for at least 28 days prior to elective surgery. Do not administer Avastin until the wound is fully healed. [See Boxed Warning, Dosage and Administration (2.4).] Necrotizing fasciitis including fatal cases, has been reported in patients treated with Avastin; usually secondary to wound healing complications, gastrointestinal perforation or fistula formation. Discontinue Avastin therapy in patients who develop necrotizing fasciitis. [See Adverse Reactions (6.3).] 5.3 Hemorrhage Avastin can result in two distinct patterns of bleeding: minor hemorrhage, most commonly Grade 1 epistaxis; and serious, and in some cases fatal, hemorrhagic events. Severe or fatal hemorrhage, including hemoptysis, gastrointestinal bleeding, hematemesis, CNS hemorrhage, epistaxis, and vaginal bleeding occurred up to five‑fold more frequently in patients receiving Avastin compared to patients receiving only chemotherapy. Across indications, the incidence of Grade ≥ 3 hemorrhagic events among patients receiving Avastin ranged from 1.2 to 4.6%. [See Adverse Reactions (6.1).] Serious or fatal pulmonary hemorrhage occurred in four of 13 (31%) patients with squamous cell histology and two of 53 (4%) patients with non‑squamous non‑small cell lung cancer receiving Avastin and chemotherapy compared to none of the 32 (0%) patients receiving chemotherapy alone. In clinical studies in non–small cell lung cancer where patients with CNS metastases who completed radiation and surgery more than 4 weeks prior to the start of Avastin were evaluated with serial CNS imaging, symptomatic Grade 2 CNS hemorrhage was documented in one of 83 Avastin‑treated patients (rate 1.2%, 95% CI 0.06%–5.93%). Intracranial hemorrhage occurred in 8 of 163 patients with previously treated glioblastoma; two patients had Grade 3–4 hemorrhage. Do not administer Avastin to patients with recent history of hemoptysis of ≥ 1/2 teaspoon of red blood. Discontinue Avastin in patients with hemorrhage. [See Boxed Warning, Dosage and Administration (2.4).] 5.4 Non‑Gastrointestinal Fistula Formation Serious and sometimes fatal non‑gastrointestinal fistula formation involving tracheo‑esophageal, bronchopleural, biliary, vaginal, renal and bladder sites

5.5 Arterial Thromboembolic Events Serious, sometimes fatal, arterial thromboembolic events (ATE) including cerebral infarction, transient ischemic attacks, myocardial infarction, angina, and a variety of other ATE occurred at a higher incidence in patients receiving Avastin compared to those in the control arm. Across indications, the incidence of Grade ≥ 3 ATE in the Avastin containing arms was 2.6% compared to 0.8% in the control arms. Among patients receiving Avastin in combination with chemotherapy, the risk of developing ATE during therapy was increased in patients with a history of arterial thromboembolism, or age greater than 65 years. [See Use in Specific Populations (8.5).] The safety of resumption of Avastin therapy after resolution of an ATE has not been studied. Discontinue Avastin in patients who experience a severe ATE. [See Dosage and Administration (2.4).] 5.6 Hypertension The incidence of severe hypertension is increased in patients receiving Avastin as compared to controls. Across clinical studies the incidence of Grade 3 or 4 hypertension ranged from 5‑18%. Monitor blood pressure every two to three weeks during treatment with Avastin. Treat with appropriate anti‑hypertensive therapy and monitor blood pressure regularly. Continue to monitor blood pressure at regular intervals in patients with Avastin‑induced or ‑exacerbated hypertension after discontinuation of Avastin. Temporarily suspend Avastin in patients with severe hypertension that is not controlled with medical management. Discontinue Avastin in patients with hypertensive crisis or hypertensive encephalopathy. [See Dosage and Administration (2.4).] 5.7 Reversible Posterior Leukoencephalopathy Syndrome (RPLS) RPLS has been reported with an incidence of < 0.1% in clinical studies. The onset of symptoms occurred from 16 hours to 1 year after initiation of Avastin. RPLS is a neurological disorder which can present with headache, seizure, lethargy, confusion, blindness and other visual and neurologic disturbances. Mild to severe hypertension may be present. Magnetic resonance imaging (MRI) is necessary to confirm the diagnosis of RPLS. Discontinue Avastin in patients developing RPLS. Symptoms usually resolve or improve within days, although some patients have experienced ongoing neurologic sequelae. The safety of reinitiating Avastin therapy in patients previously experiencing RPLS is not known. [See Dosage and Administration (2.4).] 5.8 Proteinuria The incidence and severity of proteinuria is increased in patients receiving Avastin as compared to controls. Nephrotic syndrome occurred in < 1% of patients receiving Avastin in clinical trials, in some instances with fatal outcome. [See Adverse Reactions (6.1).] In a published case series, kidney biopsy of six patients with proteinuria showed findings consistent with thrombotic microangiopathy. Monitor proteinuria by dipstick urine analysis for the development or worsening of proteinuria with serial urinalyses during Avastin therapy. Patients with a 2 + or greater urine dipstick reading should undergo further assessment with a 24‑hour urine collection. Suspend Avastin administration for ≥ 2 grams of proteinuria/24 hours and resume when proteinuria is < 2 gm/24 hours. Discontinue Avastin in patients with nephrotic syndrome. Data from a postmarketing safety study showed poor correlation between UPCR (Urine Protein/Creatinine Ratio) and 24 hour urine protein (Pearson Correlation 0.39 (95% CI 0.17, 0.57). [See Use in Specific Populations (8.5).] The safety of continued Avastin treatment in patients with moderate to severe proteinuria has not been evaluated. [See Dosage and Administration (2.4).] 5.9 Infusion Reactions Infusion reactions reported in the clinical trials and post‑marketing experience include hypertension, hypertensive crises associated with neurologic signs and symptoms, wheezing, oxygen desaturation, Grade 3 hypersensitivity, chest pain, headaches, rigors, and diaphoresis. In clinical studies, infusion reactions with the first dose of Avastin were uncommon (< 3%) and severe reactions occurred in 0.2% of patients. Stop infusion if a severe infusion reaction occurs and administer appropriate medical therapy. [See Dosage and Administration (2.4).] 5.10 Ovarian Failure The incidence of ovarian failure was higher (34% vs. 2%) in premenopausal women receiving Avastin in combination with mFOLFOX chemotherapy as compared to those receiving mFOLFOX chemotherapy alone for adjuvant treatment for colorectal cancer, a use for which Avastin is not approved. Inform females of reproductive potential of the risk of ovarian failure prior to starting treatment with Avastin. [See Adverse Reactions (6.1), Use in Specific Populations (8.6).] 6 ADVERSE REACTIONS The following serious adverse reactions are discussed in greater detail in other sections of the label: • Gastrointestinal Perforations [See Boxed Warning, Dosage and Administration (2.4), Warnings and Precautions (5.1).] • Surgery and Wound Healing Complications [See Boxed Warning, Dosage and Administration (2.4), Warnings and Precautions (5.2).] • Hemorrhage [See Boxed Warning, Dosage and Administration (2.4), Warnings and Precautions (5.3).] • Non‑Gastrointestinal Fistula Formation [See Dosage and Administration (2.4), Warnings and Precautions (5.4).] • Arterial Thromboembolic Events [See Dosage and Administration (2.4), Warnings and Precautions (5.5).] • Hypertensive Crisis [See Dosage and Administration (2.4), Warnings and Precautions (5.6).] • Reversible Posterior Leukoencephalopathy Syndrome [See Dosage and Administration (2.4), Warnings and Precautions (5.7).] • Proteinuria [See Dosage and Administration (2.4), Warnings and Precautions (5.8).] • Ovarian Failure [See Warnings and Precautions (5.10), Use in Specific Populations (8.6).] The most common adverse reactions observed in Avastin patients at a rate > 10% and at least twice the control arm rate, are epistaxis, headache, hypertension, rhinitis, proteinuria, taste alteration, dry skin, rectal hemorrhage, lacrimation disorder, back pain and exfoliative dermatitis. Across all studies, Avastin was discontinued in 8.4 to 21% of patients because of adverse reactions. 6.1 Clinical Trial Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. The data below reflect exposure to Avastin in 4599 patients with CRC, non‑squamous NSCLC, glioblastoma, or mRCC trials including controlled (Studies 1, 2, 4, 5 and 8) or uncontrolled, single arm (Study 6) treated at the recommended dose and schedule for a median of 8 to 23 doses of Avastin. [See Clinical Studies (14).] The population was aged 18‑89 years (median 60 years), 45.4% male and 85.8% (3729/4345) White. The population included 2184 first‑ and second‑line mCRC patients who received a median of 10 doses of Avastin, 480 first‑line metastatic NSCLC patients who received a median of 8 doses of Avastin, 163 glioblastoma patients who received a median of 9 doses of Avastin, and 337 mRCC patients who received a median of 16 doses of Avastin. These data also reflect exposure to Avastin in 363 patients with metastatic breast cancer (MBC)

who received a median of 9.5 doses of Avastin, 669 female adjuvant CRC patients who received a median of 23 doses of Avastin and exposure to Avastin in 403 previously untreated patients with diffuse large B‑cell lymphoma (DLBCL) who received a median of 8 doses of Avastin. Avastin is not approved for use in MBC, adjuvant CRC, or DLBCL.

Metastatic Colorectal Cancer (mCRC) The data in Table 1 and Table 2 were obtained in Study 1, a randomized, double‑blind, controlled trial comparing chemotherapy plus Avastin with chemotherapy plus placebo. Avastin was administered at 5 mg/kg every 2 weeks. All Grade 3–4 adverse events and selected Grade 1–2 adverse events (hypertension, proteinuria, thromboembolic events) were collected in the entire study population. Severe and life‑threatening (Grade 3–4) adverse events, which occurred at a higher incidence ( ≥ 2%) in patients receiving bolus‑IFL plus Avastin as compared to bolus‑IFL plus placebo, are presented in Table 1. Table 1 NCI‑CTC Grade 3−4 Adverse Events in Study 1 (Occurring at Higher Incidence [ ≥ 2 %] Avastin vs. Control)

perforation (2%), and RPLS (1%). The incidence of Grade 3–5 events in these 163 patients were bleeding/hemorrhage (2%), CNS hemorrhage (1%), hypertension (5%), venous thromboembolic event (7%), arterial thromboembolic event (3%), wound‑healing complications (3%), proteinuria (1%), and gastrointestinal perforation (2%).

8.3 Nursing Mothers It is not known whether Avastin is secreted in human milk. Human IgG is excreted in human milk, but published data suggest that breast milk antibodies do not enter the neonatal and infant circulation in substantial amounts. Because many drugs are secreted in human milk and because of the potential for serious adverse reactions in nursing infants from bevacizumab, a decision should be made whether to discontinue nursing or discontinue drug, taking into account the half‑life of the bevacizumab (approximately 20 days [range 11–50 days]) and the importance of the drug to the mother. [See Clinical Pharmacology (12.3).]

Surgery and Wound Healing Complications The incidence of post‑operative wound healing and/or bleeding complications was increased in patients with mCRC receiving Avastin as compared to patients receiving only chemotherapy. Among patients requiring surgery on or within 60 days of receiving study treatment, wound healing and/or bleeding complications occurred in 15% (6/39) of patients receiving bolus‑IFL plus Avastin as compared to 4% (1/25) of patients who received bolus‑IFL alone. In Study 6, events of post‑operative wound healing complications (craniotomy site wound dehiscence and cerebrospinal fluid leak) occurred in patients with previously treated glioblastoma: 3/84 patients in the Avastin alone arm and 1/79 patients in the Avastin plus irinotecan arm. [See Boxed Warning, Dosage and Administration (2.4), Warnings and Precautions (5.2).]

NCI‑CTC Grade 3‑4 Events Body as a Whole Asthenia Abdominal Pain Pain Cardiovascular Hypertension Deep Vein Thrombosis Intra‑Abdominal Thrombosis Syncope Digestive Diarrhea Constipation Hemic/Lymphatic Leukopenia Neutropeniaa

Hemorrhage The incidence of epistaxis was higher (35% vs. 10%) in patients with mCRC receiving bolus‑IFL plus Avastin compared with patients receiving bolus‑IFL plus placebo. All but one of these events were Grade 1 in severity and resolved without medical intervention. Grade 1 or 2 hemorrhagic events were more frequent in patients receiving bolus‑IFL plus Avastin when compared to those receiving bolus‑IFL plus placebo and included gastrointestinal hemorrhage (24% vs. 6%), minor gum bleeding (2% vs. 0), and vaginal hemorrhage (4% vs. 2%). [See Boxed Warning, Dosage and Administration (2.4), Warnings and Precautions (5.3).] Venous Thromboembolic Events The overall incidence of Grade 3–4 venous thromboembolic events in Study 1 was 15.1% in patients receiving bolus‑IFL plus Avastin and 13.6% in patients receiving bolus‑IFL plus placebo. In Study 1, more patients in the Avastin containing arm experienced deep venous thrombosis (34 vs. 19 patients ) and intra‑abdominal venous thrombosis (10 vs. 5 patients). The risk of developing a second thromboembolic event while on Avastin and oral anticoagulants was evaluated in two randomized studies. In Study 1, 53 patients (14%) on the bolus‑IFL plus Avastin arm and 30 patients (8%) on the bolus‑IFL plus placebo arm received full dose warfarin following a venous thromboembolic event (VTE). Among these patients, an additional thromboembolic event occurred in 21% (11/53) of patients receiving bolus‑IFL plus Avastin and 3% (1/30) of patients receiving bolus‑IFL alone. In a second, randomized, 4‑arm study in 1401 patients with mCRC, prospectively evaluating the incidence of VTE (all grades), the overall incidence of first VTE was higher in the Avastin containing arms (13.5%) than the chemotherapy alone arms (9.6%). Among the 116 patients treated with anticoagulants following an initial VTE event (73 in the Avastin plus chemotherapy arms and 43 in the chemotherapy alone arms), the overall incidence of subsequent VTEs was also higher among the Avastin treated patients (31.5% vs. 25.6%). In this subgroup of patients treated with anticoagulants, the overall incidence of bleeding, the majority of which were Grade 1, was higher in the Avastin treated arms than the chemotherapy arms (27.4% vs. 20.9%). [See Dosage and Administration (2.4).]

Congestive Heart Failure (CHF) The incidence of Grade ≥ 3 left ventricular dysfunction was 1.0% in patients receiving Avastin compared to 0.6% in the control arm across indications. In patients with metastatic breast cancer (MBC), an indication for which Avastin is not approved, the incidence of Grade 3–4 CHF was increased in patients in the Avastin plus paclitaxel arm (2.2%) as compared to the control arm (0.3%). Among patients receiving prior anthracyclines for MBC, the rate of CHF was 3.8% for patients receiving Avastin as compared to 0.6% for patients receiving paclitaxel alone. The safety of continuation or resumption of Avastin in patients with cardiac dysfunction has not been studied. In previously untreated patients with diffuse large B‑cell lymphoma (DLBCL), an indication for which Avastin is not approved, the incidence of CHF and decline in left‑ventricular ejection fraction (LVEF) were significantly increased in the Avastin plus R‑CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone) arm (n=403) compared to the placebo plus R‑CHOP arm (n=379); both regimens were given for 6 to 8 cycles. At the completion of R‑CHOP therapy, the incidence of CHF was 10.9% in the Avastin plus R‑CHOP arm compared to 5.0% in the R‑CHOP alone arm [relative risk (95% CI) of 2.2 (1.3, 3.7)]. The incidence of a LVEF event, defined as a decline from baseline of 20% or more in LVEF or a decline from baseline of 10% or more to a LVEF value of less than 50%, was also increased in the Avastin plus R‑CHOP arm (10.4%) compared to the R‑CHOP alone arm (5.0%). Time to onset of left‑ventricular dysfunction or CHF was 1‑6 months after initiation of therapy in at least 85% of the patients and was resolved in 62% of the patients experiencing CHF in the Avastin arm compared to 82% in the control arm. Ovarian Failure The incidence of new cases of ovarian failure (defined as amenorrhoea lasting 3 or more months, FSH level ≥ 30 mIU/mL and a negative serum β‑HCG pregnancy test) was prospectively evaluated in a subset of 179 women receiving mFOLFOX chemotherapy alone (n = 84) or with Avastin (n = 95). New cases of ovarian failure were identified in 34% (32/95) of women receiving Avastin in combination with chemotherapy compared with 2% (2/84) of women receiving chemotherapy alone [relative risk of 14 (95% CI 4, 53)]. After discontinuation of Avastin treatment, recovery of ovarian function at all time points during the post‑treatment period was demonstrated in 22% (7/32) of the Avastin‑treated women. Recovery of ovarian function is defined as resumption of menses, a positive serum β‑HCG pregnancy test, or a FSH level < 30 mIU/mL during the post‑ treatment period. Long term effects of Avastin exposure on fertility are unknown. [See Warnings and Precautions (5.10), Use in Specific Populations (8.6).]

Avastin in Combination with FOLFOX4 in Second‑line mCRC Only Grade 3‑5 non‑hematologic and Grade 4–5 hematologic adverse events related to treatment were collected in Study 2. The most frequent adverse events (selected Grade 3–5 non‑hematologic and Grade 4–5 hematologic adverse events) occurring at a higher incidence (≥2%) in 287 patients receiving FOLFOX4 plus Avastin compared to 285 patients receiving FOLFOX4 alone were fatigue (19% vs. 13%), diarrhea (18% vs. 13%), sensory neuropathy (17% vs. 9%), nausea (12% vs. 5%), vomiting (11% vs. 4%), dehydration (10% vs. 5%), hypertension (9% vs. 2%), abdominal pain (8% vs. 5%), hemorrhage (5% vs. 1%), other neurological (5% vs. 3%), ileus (4% vs. 1%) and headache (3% vs. 0%). These data are likely to under‑estimate the true adverse event rates due to the reporting mechanisms used in Study 2. Avastin in Combination with Fluoropyrimidine‑Irinotecan or Fluoropyrimidine‑ Oxaliplatin Based Chemotherapy in Second‑line mCRC Patients who have Progressed on an Avastin Containing Regimen in First‑line mCRC: No new safety signals were observed in Study 4 when Avastin was administered in second line mCRC patients who progressed on an Avastin containing regimen in first line mCRC. The safety data was consistent with the known safety profile established in first and second line mCRC. Unresectable Non‑Squamous Non‑Small Cell Lung Cancer (NSCLC) Only Grade 3‑5 non‑hematologic and Grade 4‑5 hematologic adverse events were collected in Study 5. Grade 3–5 non‑hematologic and Grade 4–5 hematologic adverse events (occurring at a higher incidence (≥2%) in 427 patients receiving PC plus Avastin compared with 441 patients receiving PC alone were neutropenia (27% vs. 17%), fatigue (16% vs. 13%), hypertension (8% vs. 0.7%), infection without neutropenia (7% vs. 3%), venous thrombus/embolism (5% vs. 3%), febrile neutropenia (5% vs. 2%), pneumonitis/pulmonary infiltrates (5% vs. 3%), infection with Grade 3 or 4 neutropenia (4% vs. 2%), hyponatremia (4% vs. 1%), headache (3% vs. 1%) and proteinuria (3% vs. 0%). Glioblastoma All adverse events were collected in 163 patients enrolled in Study 6 who either received Avastin alone or Avastin plus irinotecan. All patients received prior radiotherapy and temozolomide. Avastin was administered at 10 mg/kg every 2 weeks alone or in combination with irinotecan. Avastin was discontinued due to adverse events in 4.8% of patients treated with Avastin alone. In patients receiving Avastin alone (N = 84), the most frequently reported adverse events of any grade were infection (55%), fatigue (45%), headache (37%), hypertension (30%), epistaxis (19%) and diarrhea (21%). Of these, the incidence of Grade ≥ 3 adverse events was infection (10%), fatigue (4%), headache (4%), hypertension (8%) and diarrhea (1%). Two deaths on study were possibly related to Avastin: one retroperitoneal hemorrhage and one neutropenic infection. In patients receiving Avastin alone or Avastin plus irinotecan (N = 163), the incidence of Avastin‑related adverse events (Grade 1–4) were bleeding/ hemorrhage (40%), epistaxis (26%), CNS hemorrhage (5%), hypertension (32%), venous thromboembolic event (8%), arterial thromboembolic event (6%), wound‑healing complications (6%), proteinuria (4%), gastrointestinal

The following adverse events were reported at a 5‑fold greater incidence in the IFN‑α plus Avastin arm compared to IFN‑α alone and not represented in Table 3: gingival bleeding (13 patients vs. 1 patient); rhinitis (9 vs.0 ); blurred vision (8 vs. 0); gingivitis (8 vs. 1); gastroesophageal reflux disease (8 vs.1 ); tinnitus (7 vs. 1); tooth abscess (7 vs.0); mouth ulceration (6 vs. 0); acne (5 vs. 0); deafness (5 vs. 0); gastritis (5 vs. 0); gingival pain (5 vs. 0) and pulmonary embolism (5 vs. 1). 6.2 Immunogenicity As with all therapeutic proteins, there is a potential for an immune response to Avastin. In clinical trials of adjuvant colon carcinoma, 14 of 2233 evaluable patients (0.63%) tested positive for treatment‑emergent anti‑bevacizumab antibodies detected by an electrochemiluminescent (ECL) based assay. Among these 14 patients, three tested positive for neutralizing antibodies against bevacizumab using an enzyme‑linked immunosorbent assay (ELISA). The clinical significance of these anti‑product antibody responses to bevacizumab is unknown. Immunogenicity assay results are highly dependent on the sensitivity and specificity of the test method and may be influenced by several factors, including sample handling, timing of sample collection, concomitant medications, and underlying disease. For these reasons, comparison of the incidence of antibodies to Avastin with the incidence of antibodies to other products may be misleading. 6.3 Postmarketing Experience The following adverse reactions have been identified during post‑approval use of Avastin. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Body as a Whole: Polyserositis Cardiovascular: Pulmonary hypertension, RPLS, Mesenteric venous occlusion Eye disorders (from unapproved intravitreal use for treatment of various ocular disorders): Permanent loss of vision; Endophthalmitis (infectious and sterile); Intraocular inflammation; Retinal detachment; Increased intraocular pressure; Hemorrhage including conjunctival, vitreous hemorrhage or retinal hemorrhage; Vitreous floaters; Ocular hyperemia; Ocular pain or discomfort Gastrointestinal: Gastrointestinal ulcer, Intestinal necrosis, Anastomotic ulceration Hemic and lymphatic: Pancytopenia Hepatobiliary disorders: Gallbladder perforation Infections and infestations: Necrotizing fasciitis, usually secondary to wound healing complications, gastrointestinal perforation or fistula formation Musculoskeletal: Osteonecrosis of the jaw Renal: Renal thrombotic microangiopathy (manifested as severe proteinuria) Respiratory: Nasal septum perforation, dysphonia Systemic Events (from unapproved intravitreal use for treatment of various ocular disorders): Arterial thromboembolic events, Hypertension, Gastrointestinal perforation, Hemorrhage

8.4 Pediatric Use The safety, effectiveness and pharmacokinetic profile of Avastin in pediatric patients have not been established. Antitumor activity was not observed among eight children with relapsed glioblastoma treated with bevacizumab and irinotecan. There is insufficient information to determine the safety and efficacy of Avastin in children with glioblastoma. Juvenile cynomolgus monkeys with open growth plates exhibited physeal dysplasia following 4 to 26 weeks exposure at 0.4 to 20 times the recommended human dose (based on mg/kg and exposure). The incidence and severity of physeal dysplasia were dose‑related and were partially reversible upon cessation of treatment. 8.5 Geriatric Use In Study 1, severe adverse events that occurred at a higher incidence ( ≥ 2%) in patients aged ≥65 years as compared to younger patients were asthenia, sepsis, deep thrombophlebitis, hypertension, hypotension, myocardial infarction, congestive heart failure, diarrhea, constipation, anorexia, leukopenia, anemia, dehydration, hypokalemia, and hyponatremia. The effect of Avastin on overall survival was similar in elderly patients as compared to younger patients. In Study 2, patients aged ≥65 years receiving Avastin plus FOLFOX4 had a greater relative risk as compared to younger patients for the following adverse events: nausea, emesis, ileus, and fatigue. In Study 5, patients aged ≥65 years receiving carboplatin, paclitaxel, and Avastin had a greater relative risk for proteinuria as compared to younger patients. [See Warnings and Precautions (5.8).] Of the 742 patients enrolled in Genentech‑sponsored clinical studies in which all adverse events were captured, 212 (29%) were age 65 or older and 43 (6%) were age 75 or older. Adverse events of any severity that occurred at a higher incidence in the elderly as compared to younger patients, in addition to those described above, were dyspepsia, gastrointestinal hemorrhage, edema, epistaxis, increased cough, and voice alteration. In an exploratory, pooled analysis of 1745 patients treated in five randomized, controlled studies, there were 618 (35%) patients aged ≥65 years and 1127 patients <65 years of age. The overall incidence of arterial thromboembolic events was increased in all patients receiving Avastin with chemotherapy as compared to those receiving chemotherapy alone, regardless of age. However, the increase in arterial thromboembolic events incidence was greater in patients aged ≥65 years (8.5% vs. 2.9%) as compared to those <65 years (2.1% vs. 1.4%). [See Warnings and Precautions (5.5).] 8.6 Females of Reproductive Potential Avastin increases the risk of ovarian failure and may impair fertility. Inform females of reproductive potential of the risk of ovarian failure prior to starting treatment with Avastin. Long term effects of Avastin exposure on fertility are unknown. In a prospectively designed substudy of 179 premenopausal women randomized to receive chemotherapy with or without Avastin, the incidence of ovarian failure was higher in the Avastin arm (34%) compared to the control arm (2%). After discontinuation of Avastin and chemotherapy, recovery of ovarian function occurred in 22% (7/32) of these Avastin‑treated patients. [See Warnings and Precautions (5.10), Adverse Reactions (6.1).] 10 OVERDOSAGE The highest dose tested in humans (20 mg/kg IV) was associated with headache in nine of 16 patients and with severe headache in three of 16 patients.

7 DRUG INTERACTIONS A drug interaction study was performed in which irinotecan was administered as part of the FOLFIRI regimen with or without Avastin. The results demonstrated no significant effect of bevacizumab on the pharmacokinetics of irinotecan or its active metabolite SN38. In a randomized study in 99 patients with NSCLC, based on limited data, there did not appear to be a difference in the mean exposure of either carboplatin or paclitaxel when each was administered alone or in combination with Avastin. However, 3 of the 8 patients receiving Avastin plus paclitaxel/carboplatin had substantially lower paclitaxel exposure after four cycles of treatment (at Day 63) than those at Day 0, while patients receiving paclitaxel/carboplatin without Avastin had a greater paclitaxel exposure at Day 63 than at Day 0. In Study 8, there was no difference in the mean exposure of interferon alfa administered in combination with Avastin when compared to interferon alfa alone. 8 USE IN SPECIFIC POPULATIONS 8.1 Pregnancy Pregnancy Category C There are no adequate or well controlled studies of bevacizumab in pregnant women. While it is not known if bevacizumab crosses the placenta, human IgG is known to cross the placenta Reproduction studies in rabbits treated with approximately 1 to 12 times the recommended human dose of bevacizumab demonstrated teratogenicity, including an increased incidence of specific gross and skeletal fetal alterations. Adverse fetal outcomes were observed at all doses tested. Other observed effects included decreases in maternal and fetal body weights and an increased number of fetal resorptions. [See Nonclinical Toxicology (13.3).] Because of the observed teratogenic effects of bevacizumab in animals and of other inhibitors of angiogenesis in humans, bevacizumab should be used during pregnancy only if the potential benefit to the pregnant woman justifies the potential risk to the fetus.

Proteinuria Grade 3–4 proteinuria ranged from 0.7 to 7.4% in Studies 1, 2, 4, 5 and 8. The overall incidence of proteinuria (all grades) was only adequately assessed in Study 8, in which the incidence was 20%. Median onset of proteinuria was 5.6 months (range 15 days to 37 months) after initiation of Avastin. Median time to resolution was 6.1 months (95% CI 2.8 months, 11.3 months). Proteinuria did not resolve in 40% of patients after median follow up of 11.2 months and required permanent discontinuation of Avastin in 30% of the patients who developed proteinuria (Study 8).

Neutropenia and Infection The incidences of neutropenia and febrile neutropenia are increased in patients receiving Avastin plus chemotherapy compared to chemotherapy alone. In Study 1, the incidence of Grade 3 or 4 neutropenia was increased in mCRC patients receiving IFL plus Avastin (21%) compared to patients receiving IFL alone (14%). In Study 5, the incidence of Grade 4 neutropenia was increased in NSCLC patients receiving paclitaxel/carboplatin (PC) plus Avastin (26.2%) compared with patients receiving PC alone (17.2%). Febrile neutropenia was also increased (5.4% for PC plus Avastin vs. 1.8% for PC alone). There were 19 (4.5%) infections with Grade 3 or 4 neutropenia in the PC plus Avastin arm of which 3 were fatal compared to 9 (2%) neutropenic infections in patients receiving PC alone, of which none were fatal. During the first 6 cycles of treatment, the incidence of serious infections including pneumonia, febrile neutropenia, catheter infections and wound infections was increased in the PC plus Avastin arm [58 patients (13.6%)] compared to the PC alone arm [29 patients (6.6%)]. In Study 6, one fatal event of neutropenic infection occurred in a patient with previously treated glioblastoma receiving Avastin alone. The incidence of any grade of infection in patients receiving Avastin alone was 55% and the incidence of Grade 3–5 infection was 10%.
