ive years of tamoxifen has long been considered the standard of care as adjuvant therapy for women with estrogen receptor–positive breast cancer. However, extending tamoxifen treatment for 10 years reduced the risk of dying by 29% durRichard Gray, MD ing the second decade after diagnosis compared with standard therapy in the international Adjuvant Tamoxifen–Longer Against Shorter (ATLAS) study. ATLAS results were presented at the 2012 San Antonio Breast Cancer Symposium and published simultaneously in The Lancet.1,2 “Five years of tamoxifen is very effective, and we know there is a carryover effect after stopping, with about a 30% reduction in mortality over the next 5

years. ATLAS evaluated whether longer-term treatment could improve upon the carryover effect of 5 years of treatment,” said Richard Gray, MD, Clinical Trial Service Unit, University of Oxford, United Kingdom.
Key Results “In the period 10 to 14 years after diagnosis, we found many fewer recurrences: 617 in the group receiving 10 years of tamoxifen vs 711 in patients treated with 5 years of tamoxifen. Breast cancer mortality and overall survival were similarly affected by longer duration of tamoxifen,” he continued. There were 331 See Page 101 breast cancer–related deaths in the 10-year group vs 397 in the 5-year group, and 639 vs 722 deaths from all causes, respectively. continued on page 12
Quality Care Symposium
Does Health-care Quality Translate to Value?

O
n December 23, 1971, President Richard Nixon signed the U.S. National Cancer Act. This date is widely considered to mark the beginning of the so-called “War on Cancer,” although that phrase was introduced only later on. Over recent decades, journalists have from time to time questioned whether we are winning this “war,” while most oncologists have tended to give a much more positive evaluation of the progress being made.1

A Payer’s Perspective on the ‘Episode of Care’ Payment Model By Ronald Piana

MORE IN THIS ISSUE
n March 23rd, 2010, President Obama signed into law the Patient Protection and Affordable Care Act, enacting sweeping change in our healthcare system. An underlying theme of the legislation is the realignment of our payment system so that it places value over volume of services. At ASCO’s first Quality Care Symposium, held recently in San Diego, Lee N. Newcomer, MD, MHA, Senior Vice President, UnitedHealthcare, discussed a payment meth-
odology that addresses that priority and that might represent one possible future for oncology practice. Dr. Newcomer began his presentation with a graph showing that unless qualitative cost measures are implemented in health care, by 2018 it will take half of a family’s income to pay for insurance premiums and out-of-pocket expenses. “Naturally, we can’t let that happen, so it’s incumbent on people like those of us here in San Diego to do something about it. To that end, I’m going to talk about a solution we attempted at UnitedHealthThe current system of oncology drug care called the ‘episode payment’ project,” said Dr. revenue dependence was created 40 Newcomer.
years ago. No one thought it would be a problem, but it is, and it’s vital that we address ways to fix it.

Last-minute ‘Fiscal Cliff’ Deal by Congress Again Averts Medicare Cuts to Physicians
A
last-minute patch to the sustainable growth rate formula included in the “fiscal cliff ” deal averted massive cuts to oncologists who care for and treat Medicare patients. “This endof-year crisis management once again demonstrates the critical need for fundamental reform of the Medicare reimbursement system,” commented ASCO President-Elect Clifford A. Hudis, MD, in a statement after the deal was achieved.
(HHS),” Dr. Hudis continued. “By allowing these as an alternative to quality reporting currently required by the Centers for Medicare and Medicaid Services, Congress has taken a critical first step towards a more robust quality monitoring system in cancer,” he said. “ASCO worked to achieve bipartisan support for this provision, which begins in 2014, and will continue to work in 2013 with the HHS Secretary and the Administration to ensure

ASH Annual Meeting Hematology
Pivotal Trial Shows Robust Activity of Ponatinib in Some Heavily Pretreated Leukemias By Alice Goodman
T
he pivotal phase II Ponatinib Ph+ ALL and CML Evaluation (PACE trial) found that 1 year of treatment with the novel investigational drug ponatinib achieved robust activity in heavily pretreated patients with chronic myeloid leukemia (CML) and Philadelphia chromosome–positive acute lymphoblastic leukemia (ALL). Responses occurred early, were generally deep and durable, and were seen regardless of mutation status or disease stage. This is promising news for patients who don’t respond or lose their response to initial treatment with the approved tyrosine kinase inhibitors imatinib (Gleevec), dasatinib (Sprycel), and nilotinib (Tasigna).

The drug is the only tyrosine kinase inhibitor currently in use known to be effective against the T315I mutation. PACE enrolled 449 patients: 270 with chronic-phase CML, 85 with accelerated-phase CML, and 94 with blast-phase CML or Philadelphia chromosome–positive ALL. At

67% had any cytogenetic response, 56% had a major cytogenetic response, and 46% had a complete cytogenetic response. A major molecular response (BCR-ABL–to–standardized control gene ratio ≤ 0.1) was achieved in 34% of this group. “Molecular responses are deep and durable,” Dr. Cortes said. “At 12 months, 91% of all chronic-phase patients with [major cytogenetic response] maintained their response,” he stated. Responses were maintained regardless of mutational status. A major cytogenetic response was achieved in 49% of patients with no mutations, 57% of those with any non-T315I mutation, and 70% of those with the T315I mutation.

Looking Ahead Dr. Cortes said that other studies of ponatinib are planned, both as front-line therapy and in patients for whom one previous tyrosine kinase inhibitor has failed. “This study shows that we have a drug that works in patients with mutations that cause resistance. These patients no longer respond to other drugs. This study, as well as others presented at the meeting, show that what we have learned about genetic abnormalities is paying off in terms of therapy,” stated Aaron D.

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.

National Comprehensive Cancer Network Appoints New CEO A Conversation with Robert W. Carlson, MD By Ronald Piana
Robert W. Carlson, MD
T
he National Comprehensive Cancer Network (NCCN) recently appointed nationally regarded breast cancer expert Robert W. Carlson, MD, as its new CEO. Previously, Dr. Carlson was Professor of Medicine in the Division of Oncology and Medical Informatics, Stanford University Medical Center; he first joined the Stanford faculty in 1983. The ASCO Post spoke with Dr. Carlson about his new role at NCCN, which commenced on January 2, 2013.
Making the Move What are your thoughts about leaving Stanford? I’ve been at Stanford for 40 of the past 42 years, so I have many significant attachments to this wonderful institution that fosters creativity and discovery in a robust atmosphere of diversity. The hardest part of leaving, of course, is separating from richly productive relationships I’ve developed over the years with colleagues, staff, students, and especially with my patients. What persuaded your decision to accept the CEO position at NCCN? Simply put, the draw to NCCN is very strong. The organization’s ongoing ability and potential to improve the lives of cancer patients globally continues to mature, and I want to be a part of that crucially important process.
Evolution of NCCN How has the NCCN changed in terms of its vision? I wasn’t in the room when NCCN was founded, but I was just outside the door, one of the early participants. When NCCN was first orga-
nized in the mid-1990s, it was really in response to the increasing influence of HMOs and the threat they represented to the ability of academic medical institutions to care for cancer patients. I think NCCN’s founding leadership envisioned the organization’s goal was based largely on its ability to negotiate contracts with payers and, in turn, respond to the threats posed by the increased leverage of HMOs. However, the payers were concerned that academic cancer centers were simply providing too much expensive care. NCCN responded by creating clinical practice guidelines so the payers would have a clear understanding of the value of care they were paying for. Over the years, NCCN guidelines have become the gold standard in the United States, viewed as optimal cancer care. In fact, the guidelines are now used, in part, as defining what payers should cover. So the core product of NCCN has been inverted over the years, changing from one designed to justify treatment delivered, to one that is used to establish what payers should cover, from the community setting to academic institutions.
opportunities to the oncology community—these are well-established, vibrant programs that we plan to continue. But we are a dynamic organization that is constantly seeking ways to improve our ability to serve the oncology community. For instance, in 2012, the NCCN website has had more than 4 million downloads of our guidelines alone. We also have more than 1.5 million unique users of our website’s products. We’re developing tools to facilitate faster and more seamless provider access to the guidelines within the context of electronic medical records (EMRs), which enables their use in real-time patient care. We are also collaborating with several pharmaceutical companies on initiatives to support translational research led by our member institutions. Further, the organization is strengthening its relationships with payers by seeking to improve the quality of information we provide. This will maximize the efficiencies among payers, providers, and patients, and at the same time minimize health-care waste in the system.
Ongoing Initiatives
You mentioned that JNCCN is flourishing, what part does the journal play in the overall picture?
These are fiscally challenging times. Are you confident that NCCN will be able to maintain and grow its large portfolio of services? There’s no question that we are living in challenging times, and it will take creativity and flexibility to accomplish our goals. But I believe we are well positioned to continue providing a wide array of cutting-edge services for the cancer community. Of course, maintaining the fiscal health of an organization of our size, reach, and ambitions requires a dedication to maintaining fiscal health. Please give the readers a snapshot of the NCCN’s ongoing work. We will continue our annual guideline conference in Florida, the Journal of the National Comprehensive Cancer Network ( JNCCN) is flourishing with a rapidly increasing impact factor, and we have our ongoing CME programs that provide educational
Role of JNCCN
a wonderful job of expanding the journal’s editorial reach and content, giving the publication an international presence.
Cost and Value of Care Cost and value of cancer care is under growing scrutiny, as CEO is this something that you feel NCCN will spend more energy on? We absolutely need to emphasize our attention to cost as it relates to value. First off, providing optimal cancer services is usually the most cost-effective and value-driven way to treat patients. Our goal of optimal care for the individual patient is firmly aligned with the value proposition of care. Plus, our member institutions, users of our guidelines and services, payers, and business collaborators are all calling for us to provide valuedriven care. The challenge, of course, is determining a cost-effective, value-based way to deliver care across a wide spectrum of interested parties, starting with payers, patients, and providers, all of whom might have a different take on what constitutes value. Then we need to address different regional and economic issues within that larger picture. These are major challenges, but I believe that NCCN will find innovative ways to address the cost-and-
Our goal of optimal care for the individual patient is firmly aligned with the value proposition of care. Plus, our member institutions, users of our guidelines and services, payers, and business collaborators are all calling for us to provide value-driven care. —Robert W. Carlson, MD
The JNCCN is a terrific educational product that allows us to publish the guidelines for wide dissemination. Importantly, the journal focuses on specific areas in the guidelines where new information or ongoing controversies can be addressed. This gives us the ability to expand the manuscript portions of the guidelines for the interested reader. Moreover, our Editor-in-Chief, Harold Burstein, MD, PhD, has done
value–driven equation. For instance, NCCN has entered into an extensive collaboration with a Washington, DC–based not-for-profit organization called the National Business Group on Health, which represents more than 350 of the nation’s Fortune 500 employers. We’re working with them to build model cancer-benefit templates that will not only be used by the group’s employers, but also by continued on page 8

growth in the coverage and accessibility for our guidelines by EMR implementation and collaborations. The organization also needs to grow its outreach and presence in the healthcare policy arena. To handle this growth will require establishing priorities and at the same time remaining in close contact with
our members and those in the community setting. It’s important to note that as we move forward into new and exciting challenges, we need to work with other professional organizations so we can all benefit from the creative energy of a collective power base. n

Disclosure: Dr. Carlson reported no potential conflicts of interest.
Managing Growth Is there any single challenge you see as you prepare to assume the role of CEO? The major challenge for NCCN is undoubtedly how we manage growth, and there are a series of dimensions that define growth. I do expect NCCN to add more member institutions— how many and how rapidly is still an emerging discussion. We should see

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
PACE Trial The approval was based on the results of the PACE trial, a multicenter,
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)] 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). t "EWJTF QBUJFOUT UIBU &3*7&%(& FYQPTVSF EVSJOH QSFHOBODZ DBO cause embryo-fetal death or severe birth defects. t *OTUSVDU GFNBMF QBUJFOUT PG SFQSPEVDUJWF QPUFOUJBM UP VTF B IJHIMZ 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. t *OTUSVDU BMM NBMF QBUJFOUT FWFO UIPTF XJUI QSJPS WBTFDUPNZ UP VTF condoms with spermicide, during sexual intercourse with female partners while taking ERIVEDGE and for at least 2 months after the last dose of ERIVEDGE. t *OTUSVDU QBUJFOUT UP JNNFEJBUFMZ DPOUBDU UIFJS IFBMUIDBSF QSPWJEFS if they (or, for males, their female partner) become pregnant or if pregnancy is suspected following exposure to ERIVEDGE. t *OTUSVDU QBUJFOUT UP JNNFEJBUFMZ SFQPSU BOZ QSFHOBODZ FYQPTVSF UP ERIVEDGE and encourage participation in the ERIVEDGE pregnancy pharmacovigilance program by calling the Genentech Adverse Event Line at 1-888-835-2555. t *OGPSN GFNBMF QBUJFOUT PG UIF QPUFOUJBM GPS TFSJPVT BEWFSTF reactions in nursing infants from ERIVEDGE, taking into account the importance of the drug to the mother. t "EWJTF QBUJFOUT OPU UP EPOBUF CMPPE PS CMPPE QSPEVDUT XIJMF UBLJOH ERIVEDGE and for at least 7 months after the last dose of ERIVEDGE. t "EWJTF QBUJFOUT UP TXBMMPX &3*7&%(& DBQTVMFT XIPMF BOE OPU UP 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).

international, single-arm clinical trial of 449 patients with disease that was resistant or intolerant to prior tyrosine kinase inhibitor therapy. The drug’s effectiveness was demonstrated by a reduction in the percentage of cells expressing the Philadelphia chromosome genetic mutation to less than 35%, a major cytogenetic response. Fifty-four percent of all patients and 70% of patients with the T315I mutation achieved major cytogenetic response. The median duration of major cytogenetic response had not yet been reached at the time of analysis. In accelerated- and blast-phase CML and Philadelphia chromosome–positive ALL, ponatinib’s effectiveness was determined by the number of patients who experienced major hematologic response. Results showed: ■■ 52% of patients with acceleratedphase CML experienced major hematologic response for a median duration of 9.5 months; ■■ 31% of patients with blast-phase CML achieved major hematologic response for a median duration of 4.7 months; and ■■ 41% of patients with Philadelphia chromosome–positive ALL achieved major hematologic response for a median duration of 3.2 months. Ponatinib is being approved with a Boxed Warning alerting patients and health care professionals that the drug can cause blood clots and liver toxicity. The most common side effects reported during clinical trials include high blood pressure, rash, abdominal pain, fatigue, headache, dry skin, constipation, fever, joint pain, and nausea. n

ASH Annual Meeting Hematology
Overall Survival Benefit Achieved with Pomalidomide in Advanced Myeloma By Caroline Helwick
S
upport for the oral immunomodulatory agent pomalidomide for multiple myeloma took a step forward when the phase III MM-003 trial showed a survival advantage in patients with advanced disease, in addition to a doubling in progression-free survival, when pomalidomide was given with low-dose dexamethasone.
Meletios A. Dimopoulos, MD
Interim Analysis The data for the open-label phase III MM-003 trial of 455 patients with relapsed or refractory myeloma were reported at the 54th Annual Meeting of the American Society of Hematology by Meletios A. Dimopoulos, MD, Professor and Chairman of the Department of Clinical Therapeutics at Alexandra Hospital in Athens, Greece.1 The study crossed the prespecified superiority boundary at the interim analysis. Therefore, the Data Safety Monitoring Board recommended that the single-agent dexamethasone arm
be discontinued and patients crossed over to receive the novel combination. “We saw a statistically significant increase in progression-free survival from about 2 months with high-dose dexamethasone to 4 months with this combination, and this difference translated to a significant overall survival advantage as well,” he said. “The benefit of pomalidomide plus low-dose dexamethasone has now been shown in the context of a prospective randomized trial, and it is superior to the current standard of care in patients with relapsed/refractory myeloma,” he maintained. Pomalidomide is considered more potent than the other available immunomodulatory drugs, thalidomide (Thalomid) and lenalidomide (Revlimid). Trials in the first-line setting are now underway, and pomalidomide is under consideration for approval by the FDA.
Overall Survival Benefit Observed After a median follow-up of 18 months, the median progression-free survival was 15.7 weeks with pomalidomide at 4 mg plus low-dose dexamethasone at 20 mg vs 8 weeks with singleagent high-dose dexamethasone (20 mg administered more frequently), which was a 55% reduction in risk (P < .001). While median overall survival was
Pomalidomide in Relapsed/Refractory Multiple Myeloma ■■ The phase III MM-003 trial showed that the combination of pomalidomide at 4 mg plus low-dose dexamethasone doubled progression-free survival time and provided a benefit in overall survival as well.
■■ Overall survival was 34 weeks with high-dose dexamethasone but has not been reached with pomalidomide/low-dose dexamethasone.
EXPERT POINT OF VIEW
S
haji K. Kumar, MD, of the Mayo Clinic in Rochester, Minnesota, commented on the findings. “Patients with myeloma are living longer, but the disease comes back in the majority. We really need new drugs, and I think the main message of this study is that clearly patients do live longer on this combination,” he said. When asked whether pomalidomide might replace lenalidomide in myeloma, he pointed Shaji K. Kumar, MD out that this would not be done in the absence of formal comparisons of the two immunomodulatory agents. “I am not sure that is even necessary,” he added, “because we look at pomalidomide as being able to work in about one-third of patients in whom lenalidomide has stopped working. We are thinking of each of these drugs as building blocks for improving survival in myeloma.” n Disclosure: Dr. Kumar reported no potential conflicts of interest.
34 weeks with high-dose dexamethasone, it has not been reached with pomalidomide/low-dose dexamethasone. This yielded a 47% risk reduction <������������������� ������������������ .001), and Dr. Difor mortality (P �������������������� mopoulos projected that the average patient would be alive for about 1 year. Good tolerability was observed in patients receiving the combination, with side effects occurring as expected. The greatest difference in tolerability from the single agent was a higher incidence of neutropenia with the combination (42% vs 15%). But the incidence of infection was similar in both arms of the study. At the time of the analysis, 45% of patients on the combination arm and 25% in the single-agent arm remained on study. More of the high-dose dexamethasone arm discontinued the regimen due to disease progression (48% vs 35%). “We believe this study provides the basis for considering this combination
as a new standard of care for hard-totreat patients who have exhausted most standard treatments for their refractory disease,” Dr. Dimopoulos stated. “And we believe See Page 101 pomalidomide may offer even greater benefit if studied among less heavily treated patients.” n

Study Details
ATLAS enrolled 6,846 women with estrogen receptor–positive breast cancer from 36 countries between 1996 and 2005. About 50% had node-positive disease, and all women had been taking tamoxifen for 5 years. Women were randomly assigned to continue with 5 more years of tamoxifen or to no more tamoxifen. The majority of women with ERpositive breast cancer were postmenopausal (89% in both groups, those

EXPERT POINT OF VIEW metrial cancer is very low in premenopausal women. In my opinion, the results of this trial will impact treatment of premenopausal women,” Dr. Ravdin stated.
Risk vs Benefit Peter Ravdin, MD
P
utting these results in perspective, Peter Ravdin, MD, moderator of a San Antonio Breast Cancer Symposium press conference where ATLAS findings were discussed, said that in the United States, there is currently a different strategy for pre- and postmenopausal women. Tamoxifen is used as primary hormonal therapy in premenopausal women, because aromatase inhibitors are not effective, he continued. “In postmenopausal women, aromatase inhibitors in general are slightly superior to tamoxifen and represent the standard of care,” he said. Dr. Ravdin is Director of the Breast Health Clinic at the Cancer Therapy and Research Center at the University of Texas Health Sciences Center San Antonio, Texas. “The results of ATLAS are most relevant for younger women. When they approach 5 years of therapy, usually we tell them to stop. ATLAS tells us that 10 years are superior to 5 years. I’m going to be comfortable telling them that. The risk of endo-
The question is open about how long to continue hormonal therapy, whether with tamoxifen or aromatase inhibitors. “The biology of the disease is such that some women are fated to have late relapses, and ATLAS suggests we can do better by treating women with hormonal therapy beyond 5 years,” he said. Dr. Ravdin cautioned that it is important to weigh risk vs benefit. “Women at high risk of late relapse, with positive nodes, and/or bigger tumors are strong candidates for continuing therapy. But a patient with a small grade 1 tumor and low risk of early and late relapse may decide she doesn’t want 5 more years of tamoxifen or hormonal therapy. The side effects can be very bothersome, and some women will have difficulty considering therapy beyond 5 years for a small benefit—an additional onethird reduction of a very small risk to begin with,” he stated.
Important Implications These results are relevant for premenopausal women for whom aromatase inhibitors are not an option, and also relevant to a wider range of women who may not want
to take aromatase inhibitors because they find the side effects difficult, said Sandra M. Swain, MD, FACP, 2012–2013 President of ASCO and Medical Director of the Washington Cancer Institute, MedStar Washington Hospital Center, Washington, DC. “These results have important implications in the United States, for patients who cannot tolerate aromatase inhibitors, which is many women. This is an underappreciated problem. Women are concerned about quality of life, and you can’t expect women in their 50s and 60s who are already beginning to feel the effects of aging to suffer for a 2% absolute benefit,” she stated.
Sandra M. Swain, MD, FACP
ATLAS also has important global health implications, Dr. Swain continued. “In some countries, money is a big issue, and tamoxifen is an inexpensive drug. Longer treatment saves lives,” she said.

on rates of recurrence or death were larger after 10 years than in the period 5 to 9 years after diagnosis. Over the period 5 to 14 years after diagnosis, the risk of breast cancer death was 12.2% for 10-year users vs 15.0% for 5-year users, for an absolute gain of 2.8% favoring the longer treatment duration. “The greatest benefit for longerterm tamoxifen emerged 10 to 14 years after diagnosis,” he said. In the second decade after diagnosis, those who took tamoxifen for 10 years had a 25% lower recurrence rate and 29% lower breast cancer mortality rate compared with those who had only 5 years of tamoxifen therapy. The trade-off with 10 years vs 5 years of treatment could be more side effects, including an increase in endometrial cancer. But in this study, the cumulative risk of death from endometrial cancer between 5 and 14 years after diagnosis was 0.4% for the continuing tamoxifen users vs 0.2% for those who did not continue. “The reduction in breast cancer deaths with 10 years of tamoxifen far outweighs this small risk of endometrial cancer and other adverse events, particularly in younger women who have a low background risk,” Prof. Gray said. “The absolute mortality gain with 10 years of tamoxifen at 15 years after diagnosis is 12%, or 1 in 8 balanced against 1 in 250 cases of endometrial cancer deaths,” he noted.
Disclosure: Prof. Gray potential conflicts of interest.

ZYTIGA® (abiraterone acetate) in combination with prednisone is indicated for the treatment of patients with metastatic castration-resistant prostate cancer (mCRPC) who have received prior chemotherapy containing docetaxel.
Important Safety Information Contraindications—ZYTIGA® may cause fetal harm (Pregnancy Category X) and is contraindicated in women who are or may become pregnant. Hypertension, Hypokalemia, and Fluid Retention Due to Mineralocorticoid Excess—Use with caution in patients with a history of cardiovascular disease or with medical conditions that might be compromised by increases in hypertension, hypokalemia, and fluid retention. ZYTIGA® may cause hypertension, hypokalemia, and fluid retention as a consequence of increased mineralocorticoid levels resulting from CYP17 inhibition. Safety has not been established in patients with LVEF < 50% or New York Heart Association (NYHA) Class III or IV heart failure because these patients were excluded from the randomized clinical trial. Control hypertension and correct hypokalemia before and during treatment. Monitor blood pressure, serum potassium, and symptoms of fluid retention at least monthly. Adrenocortical Insufficiency (AI)—AI has been reported in clinical trials in patients receiving ZYTIGA® in combination with prednisone, after an interruption of daily steroids, and/or with concurrent infection or stress. Use caution and monitor for symptoms and signs of AI if prednisone is stopped or withdrawn, if prednisone dose is reduced, or if the patient experiences unusual stress. Symptoms and signs of AI may be masked by adverse reactions associated with mineralocorticoid excess seen in patients treated with ZYTIGA®. Perform appropriate tests, if indicated, to confirm AI. Increased dosages of corticosteroids may be used before, during, and after stressful situations. Hepatotoxicity—Increases in liver enzymes have led to drug interruption, dose modification, and/or discontinuation. Monitor liver function and modify, withhold, or discontinue ZYTIGA® dosing as recommended (see Prescribing Information for more information). Measure serum transaminases [alanine aminotransferase (ALT) and aspartate aminotransferase (AST)] and bilirubin levels prior to starting treatment with ZYTIGA®, every two weeks for the first three months of treatment, and monthly thereafter. Promptly measure serum total bilirubin, AST, and ALT if clinical symptoms or signs suggestive of hepatotoxicity develop. Elevations of AST, ALT, or bilirubin from the patient’s baseline should prompt more frequent monitoring. If at any time AST or ALT rise above five times the upper limit of normal (ULN) or the bilirubin rises above three times the ULN, interrupt ZYTIGA® treatment and closely monitor liver function. Food Effect—ZYTIGA® must be taken on an empty stomach. Exposure of abiraterone increases up to 10-fold when abiraterone acetate is taken with meals. No food should be eaten for at least two hours before the dose of ZYTIGA® is taken and for at least one hour after the dose of ZYTIGA® is taken. Abiraterone Cmax and AUC0-∞ (exposure) were increased up to 17- and 10-fold higher, respectively, when a single dose of abiraterone acetate was administered with a meal compared to a fasted state.
Drug Interactions—ZYTIGA® is an inhibitor of the hepatic drug-metabolizing enzyme CYP2D6. Avoid coadministration with CYP2D6 substrates that have a narrow therapeutic index. If an alternative cannot be used, exercise caution and consider a dose reduction of the CYP2D6 substrate. Additionally, abiraterone is a substrate of CYP3A4 in vitro. Strong inhibitors and inducers of CYP3A4 should be avoided or used with caution. Use in Specific Populations—The safety of ZYTIGA® in patients with baseline severe hepatic impairment has not been studied. These patients should not receive ZYTIGA®.

Adverse Reactions—The most common adverse reactions (≥ 5%) are joint swelling or discomfort, hypokalemia, edema, muscle discomfort, hot flush, diarrhea, urinary tract infection, cough, hypertension, arrhythmia, urinary frequency, nocturia, dyspepsia, fractures and upper respiratory tract infection.
ZYTIGA® (abiraterone acetate) Tablets Brief Summary of Prescribing Information. INDICATIONS AND USAGE ZYTIGA in combination with prednisone is indicated for the treatment of patients with metastatic castrationresistant prostate cancer (CRPC) who have received prior chemotherapy containing docetaxel. CONTRAINDICATIONS Pregnancy: ZYTIGA may cause fetal harm when administered to a pregnant woman. ZYTIGA is contraindicated in women who are or may become pregnant. 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 the fetus. WARNINGS AND PRECAUTIONS Hypertension, Hypokalemia and Fluid Retention Due to Mineralocorticoid Excess: Use ZYTIGA with caution in patients with a history of cardiovascular disease. ZYTIGA may cause hypertension, hypokalemia, and fluid retention as a consequence of increased mineralocorticoid levels resulting from CYP17 inhibition [see Adverse Reactions and Clinical Pharmacology (12.1) in full Prescribing Information]. Co-administration of a corticosteroid suppresses adrenocorticotropic hormone (ACTH) drive, resulting in a reduction in the incidence and severity of these adverse reactions. Use caution when treating patients whose underlying medical conditions might be compromised by increases in blood pressure, hypokalemia or fluid retention, e.g., those with heart failure, recent myocardial infarction or ventricular arrhythmia. The safety of ZYTIGA in patients with left ventricular ejection fraction <50% or NYHA Class III or IV heart failure has not been established because these patients were excluded from the randomized clinical trial. Monitor patients for hypertension, hypokalemia, and fluid retention at least once a month. Control hypertension and correct hypokalemia before and during treatment with ZYTIGA. Adrenocortical Insufficiency: Adrenocortical insufficiency has been reported in clinical trials in patients receiving ZYTIGA in combination with prednisone, following interruption of daily steroids and/or with concurrent infection or stress. Use caution and monitor for symptoms and signs of adrenocortical insufficiency, particularly if patients are withdrawn from prednisone, have prednisone dose reductions, or experience unusual stress. Symptoms and signs of adrenocortical insufficiency may be masked by adverse reactions associated with mineralocorticoid excess seen in patients treated with ZYTIGA. If clinically indicated, perform appropriate tests to confirm the diagnosis of adrenocortical insufficiency. Increased dosage of corticosteroids may be indicated before, during and after stressful situations [see Warnings and Precautions]. Hepatotoxicity: Marked increases in liver enzymes leading to drug discontinuation or dosage modification have occurred [see Adverse Reactions]. Measure serum transaminases (ALT and AST) and bilirubin levels prior to starting treatment with ZYTIGA, every two weeks for the first three months of treatment and monthly thereafter. In patients with baseline moderate hepatic impairment receiving a reduced ZYTIGA dose of 250 mg, measure ALT, AST, and bilirubin prior to the start of treatment, every week for the first month, every two weeks for the following two months of treatment and monthly thereafter. Promptly measure serum total bilirubin, AST, and ALT if clinical symptoms or signs suggestive of hepatotoxicity develop. Elevations of AST, ALT, or bilirubin from the patient’s baseline should prompt more frequent monitoring. If at any time AST or ALT rise above five times the ULN, or the bilirubin rises above three times the ULN, interrupt ZYTIGA treatment and closely monitor liver function. Re-treatment with ZYTIGA at a reduced dose level may take place only after return of liver function tests to the patient’s baseline or to AST and ALT less than or equal to 2.5X ULN and total bilirubin less than or equal to 1.5X ULN [see Dosage and Administration (2.2) in full Prescribing Information]. The safety of ZYTIGA re-treatment of patients who develop AST or ALT greater than or equal to 20X ULN and/or bilirubin greater than or equal to 10X ULN is unknown. Food Effect: ZYTIGA must be taken on an empty stomach. No food should be consumed for at least two hours before the dose of ZYTIGA is taken and for at least one hour after the dose of ZYTIGA is taken. Abiraterone Cmax and AUC0-∞ (exposure) were increased up to 17- and 10-fold higher, respectively, when a single dose of abiraterone acetate was administered with a meal compared to a fasted state. The safety of these increased exposures when multiple doses of abiraterone acetate are taken with food has not been assessed [see Dosage and Administration (2.1) and Clinical Pharmacology (12.3) in full Prescribing Information]. ADVERSE REACTIONS The following are discussed in more detail in other sections of the labeling: Hypertension, hypokalemia, and fluid retention due to mineralocorticoid excess [see Warnings and Precautions]. Adrenocortical insufficiency [see Warnings and Precautions]. Hepatotoxicity [see Warnings and Precautions]. Food effect [see Warnings and Precautions]. 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 clinical practice. In a placebo-controlled, multicenter phase 3 clinical trial of patients with metastatic castration-resistant prostate cancer who were using a gonadotropin-releasing hormone (GnRH) agonist or were previously treated with orchiectomy, ZYTIGA was administered at a dose of 1,000 mg daily in combination with prednisone 5 mg twice daily in the active treatment arm (N = 791). Placebo plus prednisone 5 mg twice daily was given to control patients (N = 394). The median duration of treatment with ZYTIGA was 8 months. The most common adverse drug reactions (≥5%) reported in clinical studies were joint swelling or discomfort, hypokalemia, edema, muscle discomfort, hot flush, diarrhea, urinary tract infection, cough, hypertension, arrhythmia, urinary frequency, nocturia, dyspepsia, fractures and upper respiratory tract infection. The most common adverse drug reactions that resulted in drug discontinuation were aspartate aminotransferase increased, alanine aminotransferase increased, urosepsis and cardiac failure (each in <1% of patients taking ZYTIGA). Adverse reactions and laboratory abnormalities related to mineralocorticoid effects were reported more commonly in patients treated with ZYTIGA than in patients treated with placebo: hypokalemia 28% versus 20%, hypertension 9% versus 7% and fluid retention (edema) 27% versus 18%, respectively (see Table 1). In patients treated with ZYTIGA, grades 3 to 4 hypokalemia occurred in 5% of patients and grades 3 to 4 hypertension was reported in 1% of patients [see Warnings and Precautions]. Table 1 shows adverse reactions due to ZYTIGA that occurred with either a ≥ 2% absolute increase in frequency compared to placebo, or were events of special interest (mineralocorticoid excess, cardiac adverse reactions, and liver toxicities).

The majority of arrhythmias were grade 1 or 2. Grade 3-4 arrhythmias occurred at similar rates in the two arms. There was one death associated with arrhythmia and one patient with sudden death in the ZYTIGA arm. No patients had sudden death or arrhythmia associated with death in the placebo arm. Cardiac ischemia or myocardial infarction led to death in 2 patients in the placebo arm and 1 death in the ZYTIGA arm. Cardiac failure resulting in death occurred in 1 patient on both arms. Hepatotoxicity: Drug-associated hepatotoxicity with elevated ALT, AST, and total bilirubin has been reported in patients treated with ZYTIGA. Across all clinical trials, liver function test elevations (ALT or AST increases of > 5X ULN) were reported in 2.3% of patients who received ZYTIGA, typically during the first 3 months after starting treatment. In the phase 3 trial, patients whose baseline ALT or AST were elevated were more likely to experience liver function test elevations than those beginning with normal values. When elevations of either ALT or AST > 5X ULN, or elevations in bilirubin > 3X ULN were observed, ZYTIGA was withheld or discontinued. In two instances marked increases in liver function tests occurred [see Warnings and Precautions]. These two patients with normal baseline hepatic function, experienced ALT or AST elevations 15 to 40X ULN and bilirubin elevations 2 to 6 X ULN. Upon discontinuation of ZYTIGA, both patients had normalization of their liver function tests and one patient was re-treated with ZYTIGA without recurrence of the elevations. In clinical trials, the following patients were excluded: patients with active hepatitis, patients with baseline ALT and/or AST ≥ 2.5X ULN in the absence of liver metastases, and patients with ALT and/or AST > 5X ULN in the presence of liver metastases. Abnormal liver function tests developing in patients participating in clinical trials were managed by treatment interruption, dose modification and/or discontinuation [see Dosage and Administration (2.2) in full Prescribing Information and Warnings and Precautions]. Patients with elevations of ALT or AST > 20X ULN were not re-treated. Other Adverse Reactions: Adrenal insufficiency occurred in two patients on the abiraterone arm of the phase 3 clinical trial (< 1%). Laboratory Abnormalities of Interest: Table 2 shows laboratory values of interest from the phase 3 placebocontrolled clinical trial. Grade 3-4 low serum phosphate (7.2%) and potassium (5.3%) occurred more frequently in the ZYTIGA arm. Table 2: Laboratory Abnormalities of Interest in a Phase 3 Placebo-Controlled Clinical Trial Abiraterone (N=791) Placebo (N=394) All Grades Grade 3-4 All Grades Grade 3-4 Laboratory Abnormality (%) (%) (%) (%) High Triglyceride 62.5 0.4 53.0 0 High AST 30.6 2.1 36.3 1.5 Low Potassium 28.3 5.3 19.8 1.0 Low Phosphorus 23.8 7.2 15.7 5.8 High ALT 11.1 1.4 10.4 0.8 High Total Bilirubin 6.6 0.1 4.6 0 DRUG INTERACTIONS Effects of Abiraterone on Drug Metabolizing Enzymes: ZYTIGA is an inhibitor of the hepatic drug-metabolizing enzyme CYP2D6. In a CYP2D6 drug-drug interaction trial, the Cmax and AUC of dextromethorphan (CYP2D6 substrate) were increased 2.8- and 2.9-fold, respectively, when dextromethorphan was given with abiraterone acetate 1,000 mg daily and prednisone 5 mg twice daily. Avoid co-administration of abiraterone acetate with substrates of CYP2D6 with a narrow therapeutic index (e.g., thioridazine). If alternative treatments cannot be used, exercise caution and consider a dose reduction of the concomitant CYP2D6 substrate drug [see Clinical Pharmacology (12.3) in full Prescribing Information]. In vitro, ZYTIGA was shown to inhibit the hepatic drug-metabolizing enzyme CYP2C8. There are no clinical data on the use of ZYTIGA with drugs that are substrates of CYP2C8. Drugs that Inhibit or Induce CYP3A4 Enzymes: Based on in vitro data, ZYTIGA is a substrate of CYP3A4. The effects of strong CYP3A4 inhibitors (e.g., ketoconazole, itraconazole, clarithromycin, atazanavir, nefazodone, saquinavir, telithromycin, ritonavir, indinavir, nelfinavir, voriconazole) or inducers (e.g., phenytoin, carbamazepine, rifampin, rifabutin, rifapentine, phenobarbital) on the pharmacokinetics of abiraterone have not been evaluated, in vivo. Avoid or use with caution, strong inhibitors and inducers of CYP3A4 during ZYTIGA treatment [see Clinical Pharmacology (12.3) in full Prescribing Information]. USE IN SPECIFIC POPULATIONS Pregnancy: Pregnancy Category X [see Contraindications]. ZYTIGA is contraindicated in women who are or may become pregnant while receiving the drug. 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 the fetus and the potential risk for pregnancy loss. Women of childbearing potential should be advised to avoid becoming pregnant during treatment with ZYTIGA. Nursing Mothers: ZYTIGA is not indicated for use in women. It is not known if abiraterone acetate 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 ZYTIGA, a decision should be made to either discontinue nursing, or discontinue the drug taking into account the importance of the drug to the mother. Pediatric Use: ZYTIGA is not indicated in children. Geriatric Use: Of the total number of patients in a phase 3 trial of ZYTIGA, 71% of patients were 65 years and over and 28% were 75 years and over. No overall differences in safety or effectiveness were observed between these elderly patients and younger patients. Patients with Hepatic Impairment: The pharmacokinetics of abiraterone were examined in subjects with baseline mild (n = 8) or moderate (n = 8) hepatic impairment (Child-Pugh Class A and B, respectively) and in 8 healthy control subjects with normal hepatic function. The systemic exposure (AUC) of abiraterone after a single oral 1,000 mg dose of ZYTIGA increased by approximately 1.1-fold and 3.6-fold in subjects with mild and moderate baseline hepatic impairment, respectively compared to subjects with normal hepatic function. No dosage adjustment is necessary for patients with baseline mild hepatic impairment. In patients with baseline moderate hepatic impairment (Child-Pugh Class B), reduce the recommended dose of ZYTIGA to 250 mg once daily. If elevations in ALT or AST >5X ULN or total bilirubin >3X ULN occur in patients with baseline moderate hepatic impairment, discontinue ZYTIGA treatment [see Dosage and Administration (2.1) and Clinical Pharmacology (12.3) in full Prescribing Information]. The safety of ZYTIGA in patients with baseline severe hepatic impairment has not been studied. These patients should not receive ZYTIGA. For patients who develop hepatotoxicity during treatment, interruption of treatment and dosage adjustment may be required [see Dosage and Administration (2.2) in full Prescribing Information, Warnings and Precautions, and Clinical Pharmacology (12.3) in full Prescribing Information]. Patients with Renal Impairment: In a dedicated renal impairment trial, the mean PK parameters were comparable between healthy subjects with normal renal function (N=8) and those with end stage renal disease (ESRD) on hemodialysis (N=8) after a single oral 1,000 mg dose of ZYTIGA. No dosage adjustment is necessary for patients with renal impairment [see Dosage and Administration (2.1) and Clinical Pharmacology (12.3) in full Prescribing Information]. OVERDOSAGE: There have been no reports of overdose of ZYTIGA during clinical studies. There is no specific antidote. In the event of an overdose, stop ZYTIGA, undertake general supportive measures, including monitoring for arrhythmias and cardiac failure and assess liver function. Storage and Handling: Store at 20°C to 25°C (68°F to 77°F); excursions permitted to 15°C to 30°C (59°F to 86°F) [see USP controlled room temperature]. Based on its mechanism of action, ZYTIGA may harm a developing fetus. Therefore, women who are pregnant or women who may be pregnant should not handle ZYTIGA without protection, e.g., gloves [see Use in Specific Populations]. Manufactured by: Patheon Inc.

Radiation Therapy for Patients with Invasive Breast Cancer: 3 Weeks Proves as Effective as 5 Weeks By Alice Goodman
T
en-year follow-up of the two-part UK Standardisation of Breast Radiotherapy Trials (START) supported the 5-year findings, demonstrating that a 3-week course of adjuvant radiation therapy is equivalent to a 5-week course of radiation for women with invasive breast cancer. The update was presented at the 2012 San Antonio Breast Cancer Symposium.1 Five-year results of START A, presented in 2008, showed that breast cancer is as sensitive to fraction size as
group) vs 39 Gy or 41.66 Gy delivered in 13 fractions over 5 weeks. “This study allowed interpolation to enable a direct estimate of fraction sensitivity,” Dr. Yarnold explained. START B had a pragmatic design, and enrolling 2,215 patients with the same criteria from 35 centers in the United Kingdom. Patients were randomly assigned to receive the same control arm treatment vs 40 Gy in 15 fractions over 3 weeks. Baseline characteristics in both tri-

late-reacting normal tissues, so there is no advantage to 2-Gy fractions. Fiveyear results of START B showed that patients can be safely and effectively treated at a total lower dose of radiation with fewer fractions than the historical standard of 50 Gy delivered over 5 weeks. “No detrimental effects of hypofractionation were identified in the trial or in any subgroup. These results support the current [National Institute for Health and Clinical Excellence] (NICE) guidelines for 40 Gy in 15 fractions as the UK standard of care for all patients with invasive breast cancer,” stated lead author John Yarnold, MD, on behalf of the START trialists. Dr. Yarnold is Professor of Clinical Oncology at The Institute of Cancer Research in London.
Study Specifics START A enrolled 2,236 women with complete surgical excision of stage I to III invasive breast cancer with one involved lymph node and no known metastasis. Patients were randomly assigned to 50 Gy delivered in 25 fractions over 5 weeks (control
als were comparable in the treatment arms. Mean age was 57 years, 25% had node-positive disease, 33% received adjuvant chemotherapy, and 75% were on adjuvant tamoxifen. Patients enrolled in START B had slightly more favorable prognostic features, Dr. Yarnold said. START A showed no evidence that the control arm was better than the other two arms in terms of adverse events, and there was clear evidence that 39 Gy was associated with fewer side effects, he continued. No significant differences were observed between 50 Gy and 41.6 Gy in tumor control; local recurrence rates were comparable. “39 Gy was slightly more gentle on
the cancer,” Dr. Yarnold commented.
Adverse Events START B showed a clear reduction in adverse events with 40������� ������ Gy delivered in 15 fractions vs 50 Gy in 25 fractions. The risk of adverse events was reduced by 23% using the shorter schedule, with an absolute 8% reduction in adverse events. According to physician assessment, rates of adverse events were lower in the 40-Gy arm, including breast shrinkage, induration, and edema. No difference in recurrence was observed between the two arms. “It is unlikely for the shorter schedule to be more than 1% inferior, and it could be 2.5% better in tumor control,” Dr. Yarnold told listeners.
Further Analysis Subgroup analysis of both START A and START B showed no difference in outcomes by age, primary surgery type, presence or absence of axillary nodes, tumor grade, use of boost radiation, and adjuvant therapy. “We conclude that there is no advantage to the continued use of 2-Gy fractions [as in 50 Gy delivered in 25 fractions]. Patients can be safely treated to a lower dose with fewer fractions than the historical standard,” Dr. Yarnold stated. During the discussion following the presentation, Dr. Yarnold said, “I see no reason why 40 Gy delivered in 15 fractions should not be adopted as the standard in other countries.”
U.S. Perspective “This study proves again that short-course radiation is as good as a longer course. The main advantages
Duration of Adjuvant Radiotherapy for Invasive Breast Cancer ■■ A shorter course of adjuvant radiation therapy—consisting of a total dose of 40 Gy delivered in 15 fractions over 3 weeks—was as effective as the standard 5-week course with 50 Gy delivered in 25 fractions in a large randomized trial.
■■ These findings were confirmed at 10-year follow-up in a large randomized trial conducted in the United Kingdom.
■■ The shorter course is now the standard of care in the UK.
of a short course is that it is more convenient for patients and it costs much less than the previous standard,” stated Alphonse Taghian, MD, PhD, Professor of Radiation Oncology at Harvard Medical School and Chief of the Breast Radiation Oncology Service at Massachusetts General Hospital in Boston. Twenty-five percent of the women who participated in the SMART trial were node-positive, and the UK standard applies to all women who require adjuvant radiation. In general, in the United States, the 3-week course is given to node-negative patients and is being used at some centers. “Some radiation oncologists in the United States are concerned about giving a 3-week course without a radiation boost. At Massachusetts General, we follow the Canadian fractionation schedule, treating the whole breast for 3 weeks and 1 day, and adding a boost over 4 days, to complete treatment in 4 weeks instead of our standard 6 weeks,” Dr. Taghian said. The Radiation Therapy Oncology Group (RTOG) is currently running a clinical trial comparing 6 weeks of standard radiation vs 3 weeks of radiation including a boost. That trial has enrolled higher-risk, node-negative patients with stage 0 to II breast cancer. “If results of this study show that the short course with the boost is as effective as the 5- or 6-week course, that will satisfy radiation oncologists who feel the boost is needed. If the study is positive, the short course will become a standard option for patients who fulfill the eligibility criteria,” he said. n Disclosure: Drs. Yarnold and Taghian reported no potential conflicts of interest.

ASH Annual Meeting Hematology
Oral Proteasome Inhibitor May Be a Game-changer in Myeloma By Caroline Helwick
A
n investigational oral proteasome inhibitor currently known as MLN9708 could make the treatment of multiple myeloma much more convenient and possibly less neurotoxic, according to the results of a phase I/II study of treatment-naive multiple myeloma patients presented at the 54th Annual Meeting of the American Society of Hematology.1
Shaji K. Kumar, MD
MLN9708, given in combination with the immunomodulatory agent lenalidomide (Revlimid), achieved an overall response rate exceeding 90%, with complete responses seen in approximately one-quarter of patients, according to Shaji K. Kumar, MD, Professor of Medicine at the Mayo Clinic, Rochester, Minnesota. “There is increasing attention toward developing highly effective regimens that at the same time will be better tolerated, more convenient, and able to be taken for a long time,” Dr. Kumar said. The thought is that combining an oral proteasome inhibitor that carries less risk for peripheral neurotoxicity with an oral immunomodulatory agent might achieve this.
First Oral Proteasome Inhibitor “The goal was to develop a highly effective, safe, and convenient all-oral regimen for the initial treatment of myeloma,” he said. MLN9708 is the first oral proteasome inhibitor to enter clinical trials in myeloma, and it appears to be less neurotoxic than its predecessor, bortezomib (Velcade). When given intravenously twice a week, bortezomib is associated with an overall rate of neuropathy of about 30%, though the new subcutaneous formulation is associated with about half the risk of this side effect. With MLN9708, severe neuropathy is generally seen in fewer
than 5% of patients. With MLN9708, “the peripheral neuropathy signal has been fairly low, compared with what we expect with
bortezomib-based regimens, and the oral delivery of the treatment makes a lot of difference to patients in terms of quality of life.” Dr. Kumar said.

the feasibility and efficacy of combining MLN9708 with lenalidomide and dexamethasone,” Dr. Kumar said. The similar combination of bortezomib plus lenalidomide/dexamethasone is a very effective regimen, he noted. The first phase of the study established the recommended phase II dose of the drug (4.0 mg weekly) in 15 patients. Another 50 patients were recruited to evaluate the efficacy of MLN9708 at 4.0 mg weekly (days 1, 8, and 15) in combination with lenalidomide (25 mg/d on days 1–21) and dexamethasone (40 See Page 101 mg/d on days 1, 8, 15, and 22) with the treatment continued for a maximum of 12 cycles. MLN9708 was then continued as maintenance therapy until disease progression. In the 20 patients who wished to undergo an autologous stem cell transplant, stem cells were successfully collected. Overall, 52 patients were evaluable for response after a median of six cycles of treatment; 58% of them achieved at least a very good partial response, including 23% with a complete response, and 32% achieved a partial response. The depth of response deepened with increasing exposure to treatment. After eight cycles, the complete
response rate was 32%. In the three patients who completed all 12 cycles, 100% of patients achieved at least a very good partial response. “We are fairly confident that with increased duration, we will see further improvement in the response numbers,” he said, adding that many patients responded after only one cycle of the regimen.
Additional Data Dr. Kumar further reported that 100% of patients had a reduction in Mprotein levels, and almost all patients with a complete response were negative for minimal residual disease. Though follow-up time is short, an estimated 93% of patients remain free of disease progression at 1 year, he added. “The number of patients at risk beyond 1 year is very low, and the data need to mature,” he cautioned. Twenty-one patients (32%) reported neuropathy, which was grade 1 in the majority (20%), grade 2 in 9%, and grade 3 in 3%. “Note that grade 3 and higher peripheral neuropathy was very low,” he said. About 40% of patients reported minor rash, fatigue, nausea, vomiting, and diarrhea, which were managed with dose reductions and supportive care. Grade 4 events were observed in just four patients. MLN9708 has entered a phase III trial in multiple myeloma, and two

EXPERT POINT OF VIEW
A
ntonio Palumbo, MD, Chief of the Myeloma Unit at the University of Torino in Italy, told The ASCO Post that the results with MLN9708 “look quite interesting,” and the drug could change the treatment of the disease. “This combination, with lenalidomide, accelerates response, and the ability to have an oral proteasome inhibitor is a real improvement,” he said. “The expectation is to have equal efficacy with an Antonio Palumbo, MD oral agent, and that would be a ‘plus’ for this disease in the future.” He added that he is more impressed with having an oral compound than by the possibility that neuropathy seems less with MLN9708 than with bortezomib. “There is less neuropathy, true, but I believe the major advance is related to the oral delivery. Today, with weekly infusion of bortezomib, neuropathy is less of a problem than it used to be.” n Disclosure: Dr. Palumbo reported no potential conflicts of interest.
additional trials are planned in newly diagnosed and in relapsed/refractory patients.
Effective in Amyloidosis The oral proteasome inhibitor MLN9708 also showed strong activity in the first-line treatment of patients with relapsed or refractory systemic light-chain amyloidosis, investigators reported at the ASH meeting.2 To date, this phase I study has enrolled 22 patients, 17 at the maximum tolerated dose of 4.0 mg and 5 at 5.5������������������������������� ������������������������������ mg. A total of 15 patients received at least one cycle and were evaluable for response. Of these, 2 patients achieved a complete response, 5 achieved at least a very good partial response, and 1 demonstrated a partial response to the drug. Hematologic response durations of up to 14.7 months were observed, and there were three cardiac organ responses among nine evaluable patients, reported Giampaolo Merlini, MD, Director of the Center for Research and Treatment
of Systemic Amyloidosis, and of the Biotechnology Research Laboratories, Scientific Institute Policlinico San Matteo, and Professor of Clinical Biochemistry, University of Pavia, Italy. The phase III TOURMALINE-ALI is ongoing in newly diagnosed amyloidosis patients. n Disclosure: Dr. Kumar reported no potential conflicts of interest.

Umbilical Cord Blood Transplant: Two Units are No Better Than One in Children with Hematologic Malignancies By Alice Goodman
U
se of two partially HLA-matched units of umbilical cord blood were not superior to a single unit if it contained an adequate number of hematopoietic stem cells, according to a randomized study by the Blood and Marrow Clinical Trials Network. Results were reported at the 54th Annual Meeting of the American Society
of Hematology (ASH) in Atlanta.1 Single units of umbilical cord blood are used in children, but adults undergoing hematopoietic stem cell transplantation often require more units. “We hypothesized that infusing two units of umbilical cord blood would improve outcomes [in children],” explained lead author John E. Wagner,
MD, Director of the Pediatric Blood and Marrow Transplant Program at the University of Minnesota in Minneapolis.
Unexpected Findings “Our findings, while unexpected, affirm that the standard transplant approach using a single unit of umbilical
cord blood is optimal so long as the unit offers a sufficient number of cells. Still, the study also showed that a double–umbilical cord blood transplant, while not better than See Page 101 an adequate singlecontinued on page 19

ABRAXANE® for Injectable Suspension (paclitaxel protein-bound particles for injectable suspension) (albumin-bound) The following is a brief summary; refer to full prescribing information for complete product information. WARNING: NEUTROPENIA • Do not administer ABRAXANE therapy to patients who have baseline neutrophil counts of less than 1,500 cells/mm3. In order to monitor the occurrence of bone marrow suppression, primarily neutropenia, which may be severe and result in infection, it is recommended that frequent peripheral blood cell counts be performed on all patients receiving ABRAXANE [see Contraindications (4), Warnings and Precautions (5.1) and Adverse Reactions (6.1, 6.2)]. • Note: An albumin form of paclitaxel may substantially affect a drug’s functional properties relative to those of drug in solution. DO NOT SUBSTITUTE FOR OR WITH OTHER PACLITAXEL FORMULATIONS. 1 INDICATIONS AND USAGE 1.1 Metastatic Breast Cancer ABRAXANE is indicated for the treatment of breast cancer after failure of combination chemotherapy for metastatic disease or relapse within 6 months of adjuvant chemotherapy. Prior therapy should have included an anthracycline unless clinically contraindicated. 1.2 Non-Small Cell Lung Cancer ABRAXANE is indicated for the first-line treatment of locally advanced or metastatic non-small cell lung cancer, in combination with carboplatin, in patients who are not candidates for curative surgery or radiation therapy. 2 DOSAGE AND ADMINISTRATION 2.1 Metastatic Breast Cancer After failure of combination chemotherapy for metastatic breast cancer or relapse within 6 months of adjuvant chemotherapy, the recommended regimen for ABRAXANE is 260 mg/m2 administered intravenously over 30 minutes every 3 weeks. 2.2 Non-Small Cell Lung Cancer The recommended dose of ABRAXANE is 100 mg/m2 administered as an intravenous infusion over 30 minutes on Days 1, 8, and 15 of each 21-day cycle. The recommended dose of carboplatin is AUC = 6 mg•min/mL on Day 1 only of each 21-day cycle, beginning immediately after the completion of ABRAXANE administration. 2.3 Dosage in Patients with Hepatic Impairment No dose adjustment is necessary for patients with mild hepatic impairment. Patients with moderate and severe hepatic impairment treated with ABRAXANE may be at increased risk of toxicities known to paclitaxel. Withhold ABRAXANE if AST >10 x ULN or bilirubin > 5 x ULN. Recommendations for dosage adjustment for the first course of therapy are shown in Table 1. For metastatic breast cancer, the dose of ABRAXANE can be increased from 130 mg/m2 up to 200 mg/m2 in patients with severe hepatic impairment in subsequent cycles based on individual tolerance. For non-small cell lung cancer, reduce the dose of ABRAXANE to 50 mg/m2 in patients with severe hepatic impairment. In subsequent cycles, the dose of ABRAXANE may be increased to 75 mg/m2 as tolerated. Monitor patients closely [see Warnings and Precautions (5.4), Use in Specific Populations (8.6), and Clinical Pharmacology (12.3)].

The need for further dose adjustments in subsequent courses should be based on individual tolerance. b A dose increase to 200 mg/m2 in subsequent courses should be considered based on individual tolerance. c Increase dose to 75 mg/m2 in subsequent courses, as tolerated.
2.4 Dose Reduction/Discontinuation Recommendations Metastatic Breast Cancer Patients who experience severe neutropenia (neutrophil <500 cells/mm3 for a week or longer) or severe sensory neuropathy during ABRAXANE therapy should have dosage reduced to 220 mg/m2 for subsequent courses of ABRAXANE. For recurrence of severe neutropenia or severe sensory neuropathy, additional dose reduction should be made to 180 mg/m2. For Grade 3 sensory neuropathy hold treatment until resolution to Grade 1 or 2, followed by a dose reduction for all subsequent courses of ABRAXANE [see Contraindications (4), Warnings and Precautions (5.1, 5.2) and Adverse Reactions (6.1)]. Non-Small Cell Lung Cancer • Do not administer ABRAXANE on Day 1 of a cycle until absolute neutrophil count (ANC) is at least 1500 cells/mm3 and platelet count is at least 100,000 cells/mm3 [see Contraindications (4),Warnings and Precautions (5.1) and Adverse Reactions (6.2)]. • In patients who develop severe neutropenia or thrombocytopenia withhold treatment until counts recover to an absolute neutrophil count of at least 1500 cells/mm3 and platelet count of at least 100,000 cells/mm3 on Day 1 or to an absolute neutrophil count of at least 500 cells/mm3 and platelet count of at least 50,000 cells/mm3 on Days 8 or 15 of the cycle. Upon resumption of dosing, permanently reduce ABRAXANE and carboplatin doses as outlined in Table 2. • Withhold ABRAXANE for Grade 3-4 peripheral neuropathy. Resume ABRAXANE and carboplatin at reduced doses (see Table 2) when peripheral neuropathy improves to Grade 1 or completely resolves [see Warnings and Precautions (5.2) and Adverse Reactions (6.2)]. Table 2: Permanent Dose Reductions for Hematologic and Neurologic Adverse Drug Reactions in NSCLC Weekly Every 3-Week Adverse Drug Reaction Occurrence ABRAXANE Dose Carboplatin Dose (mg/m2) (AUC mg•min/mL) Neutropenic Fever (ANC less than 500/mm3 First 75 4.5 with fever >38°C) OR Delay of next cycle by more than 7 days for ANC Second 50 3 less than 1500/mm3 OR ANC less than 500/mm3 Third Discontinue Treatment for more than 7 days First 75 4.5 Platelet count less than 50,000/mm3 Second Discontinue Treatment First 75 4.5 Severe sensory Neuropathy – Second 50 3 Grade 3 or 4 Third Discontinue Treatment 4 CONTRAINDICATIONS • ABRAXANE should not be used in patients who have baseline neutrophil counts of < 1,500 cells/mm3. • Patients who experience a severe hypersensitivity reaction to ABRAXANE should not be rechallenged with the drug. 5 WARNINGS AND PRECAUTIONS 5.1 Hematologic Effects Bone marrow suppression (primarily neutropenia) is dose-dependent and a dose-limiting toxicity of ABRAXANE. In clinical studies, Grade 3-4 neutropenia occurred in 34% of patients with metastatic breast cancer (MBC) and 47% of patients with non-small cell lung cancer (NSCLC). Monitor for myelotoxicity by performing complete blood cell counts frequently, including prior to dosing on Day 1 (for MBC) and Days 1, 8, and 15 (for NSCLC). Do not administer ABRAXANE to patients with baseline absolute neutrophil counts (ANC) of less than 1,500 cells/mm3. In the case of severe neutropenia (<500 cells/mm3 for seven days or more) during a course of ABRAXANE therapy, reduce the dose of ABRAXANE in subsequent courses in patients with either MBC or NSCLC. In patients with MBC, resume treatment with every-3-week cycles of ABRAXANE after ANC recovers to a level >1,500 cells/mm3 and platelets recover to a level >100,000 cells/mm3. In patients with NSCLC, resume treatment if recommended (see Dosage and Administration, Table 2) at permanently reduced doses for both weekly ABRAXANE and every-3-week carboplatin after ANC recovers to at least 1500 cells/mm3 and platelet count of at least 100,000 cells/mm3 on Day 1 or to an ANC of at least 500 cells/mm3 and platelet count of at
least 50,000 cells/mm3 on Days 8 or 15 of the cycle [see Dosage and Administration (2.4)]. 5.2 Nervous System Sensory neuropathy is dose- and schedule-dependent [see Adverse Reactions (6.1, 6.2)]. The occurrence of Grade 1 or 2 sensory neuropathy does not generally require dose modification. If ≥ Grade 3 sensory neuropathy develops, treatment should be withheld until resolution to Grade 1 or 2 for metastatic breast cancer or until resolution to ≤ Grade 1 for NSCLC followed by a dose reduction for all subsequent courses of ABRAXANE [see Dosage and Administration (2.4)]. 5.3 Hypersensitivity Severe and sometimes fatal hypersensitivity reactions, including anaphylactic reactions, have been reported. Patients who experience a severe hypersensitivity reaction to ABRAXANE should not be re-challenged with this drug. 5.4 Hepatic Impairment Because the exposure and toxicity of paclitaxel can be increased with hepatic impairment, administration of ABRAXANE in patients with hepatic impairment should be performed with caution. The starting dose should be reduced for patients with moderate or severe hepatic impairment [see Dosage and Administration (2.3), Use in Specific Populations (8.6) and Clinical Pharmacology (12.3)]. 5.5 Albumin (Human) ABRAXANE contains albumin (human), a derivative of human blood. Based on effective donor screening and product manufacturing processes, it carries a remote risk for transmission of viral diseases. A theoretical risk for transmission of Creutzfeldt-Jakob Disease (CJD) also is considered extremely remote. No cases of transmission of viral diseases or CJD have ever been identified for albumin. 5.6 Use in Pregnancy ABRAXANE can cause fetal harm when administered to a pregnant woman. Administration of paclitaxel protein-bound particles to rats during pregnancy at doses lower than the maximum recommended human dose, based on body surface area, caused embryo-fetal toxicities, including intrauterine mortality, increased resorptions, reduced numbers of live fetuses, and malformations. There are no adequate and well-controlled studies in pregnant women receiving ABRAXANE. 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. Women of childbearing potential should be advised to avoid becoming pregnant while receiving ABRAXANE [see Use in Specific Populations (8.1)]. 5.7 Use in Men Men should be advised not to father a child while receiving ABRAXANE [see Nonclinical Toxicology (13.1)]. 6 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 practice. The most common adverse reactions (≥ 20%) with single-agent use of ABRAXANE in metastatic breast cancer are alopecia, neutropenia, sensory neuropathy, abnormal ECG, fatigue/asthenia, myalgia/arthralgia, AST elevation, alkaline phosphatase elevation, anemia, nausea, infections, and diarrhea [see Adverse Reactions (6.1)]. The most common adverse reactions (≥ 20%) of ABRAXANE in combination with carboplatin for non-small cell lung cancer are anemia, neutropenia, thrombocytopenia, alopecia, peripheral neuropathy, nausea, and fatigue [see Adverse Reactions (6.2)] The most common serious adverse reactions of ABRAXANE in combination with carboplatin for non-small cell lung cancer are anemia (4%) and pneumonia (3%). The most common adverse reactions resulting in permanent discontinuation of ABRAXANE were neutropenia (3%), thrombocytopenia (3%), and peripheral neuropathy (1%). The most common adverse reactions resulting in dose reduction of ABRAXANE were neutropenia (24%), thrombocytopenia (13%), and anemia (6%). The most common adverse reactions leading to withholding or delay in ABRAXANE dosing were neutropenia (41%), thrombocytopenia (30%), and anemia (16%). 6.1 Clinical Trials Experience in Metastatic Breast Cancer Table 3 shows the frequency of important adverse events in the randomized comparative trial for the patients who received either single-agent ABRAXANE or paclitaxel injection for the treatment of metastatic breast cancer.

Adverse Event Experiences by Body System Hematologic Disorders Neutropenia was dose dependent and reversible. Among patients with metastatic breast cancer in the randomized trial, neutrophil counts declined below 500 cells/mm3 (Grade 4) in 9% of the patients treated with a dose of 260 mg/m2 compared to 22% in patients receiving paclitaxel injection at a dose of 175 mg/m2. Pancytopenia has been observed in clinical trials. Infections Infectious episodes were reported in 24% of the patients treated with ABRAXANE. Oral candidiasis, respiratory tract infections and pneumonia were the most frequently reported infectious complications. Hypersensitivity Reactions (HSRs) Grade 1 or 2 HSRs occurred on the day of ABRAXANE administration and consisted of dyspnea (1%) and flushing, hypotension, chest pain, and arrhythmia (all <1%). The use of ABRAXANE in patients previously exhibiting hypersensitivity to paclitaxel injection or human albumin has not been studied. Cardiovascular Hypotension, during the 30-minute infusion, occurred in 5% of patients. Bradycardia, during the 30-minute infusion, occurred in <1% of patients. These vital sign changes most often caused no symptoms and required neither specific therapy nor treatment discontinuation. Severe cardiovascular events possibly related to single-agent ABRAXANE occurred in approximately 3% of patients. These events included cardiac ischemia/infarction, chest pain, cardiac arrest, supraventricular tachycardia, edema, thrombosis, pulmonary thromboembolism, pulmonary emboli, and hypertension. Cases of cerebrovascular attacks (strokes) and transient ischemic attacks have been reported. Electrocardiogram (ECG) abnormalities were common among patients at baseline. ECG abnormalities on study did not usually result in symptoms, were not dose-limiting, and required no intervention. ECG abnormalities were noted in 60% of patients. Among patients with a normal ECG prior to study entry, 35% of all patients developed an abnormal tracing while on study. The most frequently reported ECG modifications were non-specific repolarization abnormalities, sinus bradycardia, and sinus tachycardia. Respiratory Dyspnea (12%), cough (7%), and pneumothorax (<1%) were reported after treatment with ABRAXANE. Neurologic The frequency and severity of sensory neuropathy increased with cumulative dose. Sensory neuropathy was the cause of ABRAXANE discontinuation in 7/229 (3%) patients. Twenty-four patients (10%) treated with ABRAXANE developed Grade 3 peripheral neuropathy; of these patients, 14 had documented improvement after a median of 22 days; 10 patients resumed treatment at a reduced dose of ABRAXANE and 2 discontinued due to peripheral neuropathy. Of the 10 patients without documented improvement, 4 discontinued the study due to peripheral neuropathy. No Grade 4 sensory neuropathies were reported. Only one incident of motor neuropathy (Grade 2) was observed in either arm of the controlled trial.
Vision Disorders Ocular/visual disturbances occurred in 13% of all patients (n=366) treated with ABRAXANE and 1% were severe. The severe cases (keratitis and blurred vision) were reported in patients who received higher doses than those recommended (300 or 375 mg/m2). These effects generally have been reversible. Arthralgia/Myalgia The symptoms were usually transient, occurred two or three days after ABRAXANE administration, and resolved within a few days. Hepatic Grade 3 or 4 elevations in GGT were reported for 14% of patients treated with ABRAXANE and 10% of patients treated with paclitaxel injection in the randomized trial. Renal Overall 11% of patients experienced creatinine elevation, 1% severe. No discontinuations, dose reductions, or dose delays were caused by renal toxicities. Other Clinical Events Nail changes (changes in pigmentation or discoloration of nail bed) have been reported. Edema occurred in 10% of patients; no patients had severe edema. Dehydration and pyrexia were also reported. 6.2 Clinical Trials Experience in Non-Small Cell Lung Cancer Adverse reactions were assessed in 514 ABRAXANE/carboplatin-treated patients and 524 paclitaxel injection/carboplatin-treated patients receiving first-line systemic treatment for locally advanced (stage IIIB) or metastatic (IV) non-small cell lung cancer (NSCLC) in a multicenter, randomized, open-label trial. ABRAXANE was administered as an intravenous infusion over 30 minutes at a dose of 100 mg/m2 on Days 1, 8, and 15 of each 21-day cycle. Paclitaxel injection was administered as an intravenous infusion over 3 hours at a dose of 200 mg/m2, following premedication. In both treatment arms carboplatin at a dose of AUC = 6 mg•min/mL was administered intravenously on Day 1 of each 21-day cycle after completion of ABRAXANE/paclitaxel infusion. The differences in paclitaxel dose and schedule between the two arms limit direct comparison of dose- and schedule-dependent adverse reactions. Among patients evaluable for adverse reactions, the median age was 60 years, 75% were men, 81% were White, 49% had adenocarcinoma, 43% had squamous cell lung cancer, 76% were ECOG PS 1. Patients in both treatment arms received a median of 6 cycles of treatment. The following common (≥ 10% incidence) adverse reactions were observed at a similar incidence in ABRAXANE plus carboplatin-treated and paclitaxel injection plus carboplatin-treated patients: alopecia 56%, nausea 27%, fatigue 25%, decreased appetite 17%, asthenia 16%, constipation 16%, diarrhea 15%, vomiting 12%, dyspnea 12%, and rash 10% (incidence rates are for the ABRAXANE plus carboplatin treatment group). Table 4 provides the frequency and severity laboratory-detected abnormalities which occurred with a difference of ≥ 5% for all grades (1-4) or ≥ 2% for Grade 3-4 toxicity between ABRAXANE plus carboplatin-treated patients or paclitaxel injection plus carboplatin-treated patients.

Grade 3 neuropathy improved to Grade 1 or resolved in 10/17 patients (59%) following interruption or discontinuation of ABRAXANE. 6.3 Post-Marketing Experience with ABRAXANE and other Paclitaxel Formulations Unless otherwise noted, the following discussion refers to the adverse reactions that have been identified during post-approval use of ABRAXANE. 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. In some instances, severe events observed with paclitaxel injection may be expected to occur with ABRAXANE. Hypersensitivity Reactions Severe and sometimes fatal hypersensitivity reactions have been reported with ABRAXANE. The use of ABRAXANE in patients previously exhibiting hypersensitivity to paclitaxel injection or human albumin has not been studied. Cardiovascular There have been reports of congestive heart failure and left ventricular dysfunction with ABRAXANE. Most of the individuals were previously exposed to cardiotoxic drugs, such as anthracyclines, or had underlying cardiac history. Respiratory There have been reports of pneumonitis, interstitial pneumonia and pulmonary embolism in patients receiving ABRAXANE and reports of radiation pneumonitis in patients receiving concurrent radiotherapy. Reports of lung fibrosis have been received as part of the continuing surveillance of paclitaxel injection safety and may also be observed with ABRAXANE. Neurologic Cranial nerve palsies and vocal cord paresis have been reported, as well as autonomic neuropathy resulting in paralytic ileus. Vision Disorders Reports in the literature of abnormal visual evoked potentials in patients treated with paclitaxel injection suggest persistent optic nerve damage. These may also be observed with ABRAXANE. Reduced visual acuity due to cystoid macular edema (CME) has been reported during treatment with ABRAXANE as well as with other taxanes. After cessation of treatment, CME improves and visual acuity may return to baseline. Hepatic Reports of hepatic necrosis and hepatic encephalopathy leading to death have been received as part of the continuing surveillance of paclitaxel injection safety and may occur following ABRAXANE treatment.
Gastrointestinal (GI) There have been reports of intestinal obstruction, intestinal perforation, pancreatitis, and ischemic colitis following ABRAXANE treatment. There have been reports of neutropenic enterocolitis (typhlitis), despite the coadministration of G-CSF, occurring in patients treated with paclitaxel injection alone and in combination with other chemotherapeutic agents. Injection Site Reaction There have been reports of extravasation of ABRAXANE. Given the possibility of extravasation, it is advisable to monitor closely the ABRAXANE infusion site for possible infiltration during drug administration. Severe events such as phlebitis, cellulitis, induration, necrosis, and fibrosis have been reported as part of the continuing surveillance of paclitaxel injection safety. In some cases the onset of the injection site reaction in paclitaxel injection patients either occurred during a prolonged infusion or was delayed by a week to ten days. Recurrence of skin reactions at a site of previous extravasation following administration of paclitaxel injection at a different site, i.e., “recall”, has been reported. Other Clinical Events Skin reactions including generalized or maculopapular rash, erythema, and pruritus have been observed with ABRAXANE. There have been case reports of photosensitivity reactions, radiation recall phenomenon, and in some patients previously exposed to capecitabine, reports of palmar-plantar erythrodysesthesia. Stevens-Johnson syndrome and toxic epidermal necrolysis have been reported. There have been reports of conjunctivitis, cellulitis, and increased lacrimation with paclitaxel injection. 6.4 Accidental Exposure No reports of accidental exposure to ABRAXANE have been received. However, upon inhalation of paclitaxel, dyspnea, chest pain, burning eyes, sore throat, and nausea have been reported. Following topical exposure, events have included tingling, burning, and redness. 7 DRUG INTERACTIONS The metabolism of paclitaxel is catalyzed by CYP2C8 and CYP3A4. In the absence of formal clinical drug interaction studies, caution should be exercised when administering ABRAXANE concomitantly with medicines known to inhibit (e.g., ketoconazole and other imidazole antifungals, erythromycin, fluoxetine, gemfibrozil, cimetidine, ritonavir, saquinavir, indinavir, and nelfinavir) or induce (e.g., rifampicin, carbamazepine, phenytoin, efavirenz, and nevirapine) either CYP2C8 or CYP3A4. There are no clinically important pharmacokinetic drug-drug interactions between carboplatin and ABRAXANE [see Clinical Pharmacology (12.3)]. 8 USE IN SPECIFIC POPULATIONS 8.1 Pregnancy Pregnancy Category D [see Warnings and Precautions (5.6)]. There are no adequate and well-controlled studies in pregnant women using ABRAXANE. Based on its mechanism of action and findings in animals, ABRAXANE can cause fetal harm when administered to a pregnant woman. 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. Women of childbearing potential should be advised to avoid becoming pregnant while receiving ABRAXANE. Administration of paclitaxel protein-bound particles to rats during pregnancy, on gestation days 7 to 17 at doses of 6 mg/m2 (approximately 2% of the daily maximum recommended human dose on a mg/m2 basis) caused embryofetal toxicities, as indicated by intrauterine mortality, increased resorptions (up to 5-fold), reduced numbers of litters and live fetuses, reduction in fetal body weight and increase in fetal anomalies. Fetal anomalies included soft tissue and skeletal malformations, such as eye bulge, folded retina, microphthalmia, and dilation of brain ventricles. A lower incidence of soft tissue and skeletal malformations were also exhibited at 3 mg/m2 (approximately 1% of the daily maximum recommended human dose on a mg/m2 basis). 8.3 Nursing Mothers It is not known whether paclitaxel is excreted in human milk. Paclitaxel and/or its metabolites were excreted into the milk of lactating rats. Because many drugs are excreted in human milk and because of the potential for serious adverse reactions in nursing infants, a decision should be made 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 ABRAXANE in pediatric patients have not been evaluated.
8.5 Geriatric Use Of the 229 patients in the randomized study who received ABRAXANE for the treatment of metastatic breast cancer, 13% were at least 65 years of age and < 2% were 75 years or older. No toxicities occurred notably more frequently among patients who received ABRAXANE. Of the 514 patients in the randomized study who received ABRAXANE and carboplatin for the first-line treatment of non-small cell lung cancer, 31% were 65 years or older and 3.5% were 75 years or older. Myelosuppression, peripheral neuropathy, and arthralgia were more frequent in patients 65 years or older compared to patients younger than 65 years old. No overall difference in effectiveness, as measured by response rates, was observed between patients 65 years or older compared to patients younger than 65 years old. 8.6 Patients with Hepatic Impairment Because the exposure and toxicity of paclitaxel can be increased in patients with hepatic impairment, the administration of ABRAXANE should be performed with caution in patients with hepatic impairment [see Dosage and Administration (2.3), Warnings and Precautions (5.4), and Clinical Pharmacology (12.3)]. 8.7 Patients with Renal Impairment The use of ABRAXANE has not been studied in patients with renal impairment. 10 OVERDOSAGE There is no known antidote for ABRAXANE overdosage. The primary anticipated complications of overdosage would consist of bone marrow suppression, sensory neurotoxicity, and mucositis. 16 HOW SUPPLIED/STORAGE AND HANDLING 16.1 How Supplied Product No.: 103450 NDC No.: 68817-134-50 100 mg of paclitaxel in a single-use vial, individually packaged in a carton. 16.2 Storage Store the vials in original cartons at 20°C to 25°C (68° F to 77°F). Retain in the original package to protect from bright light. 16.3 Handling and Disposal Procedures for proper handling and disposal of anticancer drugs should be considered. Several guidelines on this subject have been published [see References (15)]. There is no general agreement that all of the procedures recommended in the guidelines are necessary or appropriate.
17 PATIENT COUNSELING INFORMATION See FDA-Approved Patient Labeling (Patient Information). • ABRAXANE injection may cause fetal harm. Advise patients to avoid becoming pregnant while receiving this drug. Women of childbearing potential should use effective contraceptives [see Warnings and Precautions (5.6) and Use in Specific Populations (8.1)]. • Advise men not to father a child while receiving ABRAXANE [see Warnings and Precautions (5.7)]. • Patients must be informed of the risk of low blood cell counts and instructed to contact their physician immediately for fever or evidence of infection. • Patients should be instructed to contact their physician for persistent vomiting, diarrhea, signs of dehydration, cough or breathing difficulties, or signs of an allergic reaction. • Patients must be informed that sensory neuropathy occurs frequently with ABRAXANE and patients should advise their physicians of numbness, tingling, pain or weakness involving the extremities [see Warnings and Precautions (5.2)]. • Explain to patients that alopecia, fatigue/asthenia, and myalgia/arthralgia occur frequently with ABRAXANE. • Patients must be informed that hypersensitivity reactions may occur, which could be severe and sometimes fatal.

ASH Annual Meeting Excellent Preliminary Results for Ibrutinib in Chronic Lymphocytic Leukemia By Alice Goodman
A
lthough still in preliminary testing with no phase III data, ibrutinib is poised to become an important new agent for patients with chronic lympho-
relapsed/refractory patients.1,2 Moreover, the drug appears to be extremely safe thus far, with little or no myelosuppression as a single agent over about 3 years of experience in clinical trials.
Highly Effective, Well Tolerated Drug CLL expert John Byrd, MD, lead author of the larger of the phase��������� II������ studies reported at the ASH meeting, stated,
“Rarely does a drug come along that helps patients this much. This drug is highly effective and very well tolerated. We are looking forward to Pharmacyclics bringing this drug forward. The quicker we get this drug across the finish line, the better.” Dr. Byrd is D.

Umbilical Cord Blood
Key Data
continued from page 18
No difference between the two treatment arms was observed in the overall rate of engraftment, Dr. Wagner continued. Both arms did better than the historical experience in children with leukemia. The rate of neutrophil recovery at day 42 was 89% with single-unit umbilical cord blood and 86% with double-unit umbilical cord blood. The incidence of grade II–IV acute graft-vs-host disease was almost identical in both arms: 56% vs 57% (with most grade II), respectively. The rate of chronic graft-vs-host disease was 28% vs 31%. “The risk of relapse was surprisingly low after umbilical cord blood transplant, with no real difference between the two arms,” he said. At 1 year, the relapse rate was 12% in the single [umbilical cord blood] arm vs 14% in the double [umbilical cord blood] arm. Typically, the relapse rate is 30% to 35% in pediatric patients. Dr. Wagner noted that the relapse rate could increase with longer follow-up, although this is not likely to change much since
unit transplant, is a useful and effective strategy in those instances where an adequate single unit is not available, such as in adults,” he said. Furthermore, having verified the safety of this approach, the double umbilical cord blood model may also be a useful tool for testing new strategies focused on improving engraftment and immune recovery, he added.
John E. Wagner, MD
The study randomly assigned 224 pediatric patients with acute leukemias to single– vs double–umbilical cord blood transplant. Importantly, all received a modified conditioning regimen containing fludarabine, which likely had a beneficial effect for all patients in this study. Both the single–umbilical cord blood and double–umbilical cord blood groups had a similar number of donor/patient mismatches.
most patients are beyond 2 years posttransplant. No significant difference in diseasefree survival was seen between the two arms: 68% vs 64%. Dr. Wagner said that the results in this trial were superior to past studies and likely attributed to the modified conditioning regimen used in the trial. The cost of transplant is an important issue, he noted. One cord unit costs on average $40,000, and two units are therefore twice as much. “Use of two units is justifiable but only in the circumstance when one unit does not contain the number of cells needed,” Dr. Wagner said, adding, “We have to continually look for ways to improve safety and reduce the cost of transplant.”
Pediatric vs Adult Patients “This study showed there is no benefit of adding a second unit when effective conditioning is used in children,” commented Vanderson Rocha, MD, Professor at Oxford University, United
Umbilical Cord Blood for Stem Cell Transplants in Children ■■ Two units of umbilical cord blood were not superior to one unit—in terms of engraftment rates, relapse, and survival—in children with hematologic malignancies who underwent transplantation.
■■ One unit remains the standard of care for children.
Ibrutinib is an investigational inhibitor of Bruton’s tyrosine kinase, a key mediator of B-cell survival See Page 101 mechanisms. In preclinical studies, ibrutinib blocked these mechanisms, driving cells into apoptosis. The novel agent is being studied alone or in combination with other drugs for the treatment of several B-cell malignancies, including CLL and small lymphocytic leukemia (SLL), a similar disease with slightly different manifestations.
Multicenter Trial The phase Ib/II, multicenter trial reported by Dr. Byrd enrolled three groups of 116 patients with CLL or SLL: elderly treatment-naive patients, relapsed/refractory patients, and highrisk relapsed/refractory patients.1 At the ASH Annual Meeting, he presentcontinued on page 20

Kingdom, and moderator of an ASH press conference where these findings were discussed. “For some years, double [umbilical cord blood] transplant was assumed to produce better outcomes for adults. With reduced-intensity conditioning, we have better outcomes and lower relapse rates for adults in first remission. There is still a role for double [umbilical cord blood] transplants in adults, for whom one unit is not sufficient.” Disclosure: Drs. Wagner and Rocha reported no potential conflicts of interest.

ed results for elderly treatment-naive patients (n = 31) and pooled results for relapsed/refractory and high-risk relapsed/refractory patients (n = 85). At 26 months, single-agent ibrutinib produced an estimated progressionfree survival rate of 96% in elderly treatment-naive patients and estimated progression-free survival rate of 75% in relapsed refractory high-risk CLL/SLL patients. Overall response rates were 68% in the treatment-naive patients at a median follow-up of 20.3 months and 71% in the relapsed/refractory and high-risk relapsed refractory group at a median follow-up of 15.7 months. At 26 months, estimated overall survival rates were 96% and 83%, respectively. Treatment-naive elderly patients and relapsed/refractory patients received oral ibrutinib at 420 mg/d or 840 mg/d; the high-risk relapsed/
refractory group received 420 mg/d. Patients with relapsed/refractory disease had been treated with at least two prior therapies; those in the high-risk group experienced a relapse within 2 years of chemoimmunotherapy. Ibrutinib was very well tolerated. Most adverse events were grade 1 or 2. The most common treatment-related adverse events were diarrhea, fatigue, nausea, and rash. Myelosuppression was rare.
Single-center Trial A second phase II, single-center study was based on 40 patients with high-risk CLL treated with the combination of ibrutinib plus rituximab (Rituxan), a standard agent in this setting.2 Overall response rate was 83% in these high-risk pretreated patients. Of 40 patients, 38 have no evidence of disease progression and are continuing therapy. This group of patients is known to
EXPERT POINT OF VIEW
M
artin Dreyling, MD, Professor at the University of Munich in Germany, said the most important lymphoma studies presented at the 2012 ASH Annual Meeting focused on ibrutinib, the first-in-class Bruton’s tyrosine kinase inhibitor. “Basic science has gone mainstream. We will see a revolution during the next 5 years in the treatment of lymphoma [and other cancers] based on understanding of both genetic alterations and epigenetics,” he commented. Martin Dreyling, MD “The Bruton’s tyrosine kinase inhibitor ibrutinib is the molecule of the year,” he continued. “This drug is a major advance—one of the three major advances that I have seen over 25 years of treating hematologic cancers. The first was rituximab [Rituxan], the second was imatinib [Gleevec], and now we have ibrutinib.” Phase II studies of ibrutinib presented at the ASH meeting focused on chronic lymphocytic leukemia (abstracts 187 and 189), mantle cell lymphoma (abstract 904), and diffuse large B-cell lymphoma (abstract 686). “These studies show impressive and unprecedented response rates with excellent tolerability,” Dr. Dreyling said. “We are all anxious to see the results of phase III trials and to have this drug available to treat our patients.” Lymphoma session moderator Joshua Brody, MD, of Mount Sinai School of Medicine, New York, was equally impressed. “Ibrutinib is great in a few tumors—mantle cell and chronic lymphocytic leukemia—and it is very encouraging in others,” he said. “We are seeing fantastic data.” He added “While we still can’t cure relapsed/refractory mantle cell lymphoma, the good news is that we now have a lot of treatment choices, and some are quite good. The overall survival rate today is certainly not as dismal as Joshua Brody, MD the historical 3- to 5-year rate that is often quoted.” n Disclosure: Dr. Dreyling is on the scientific advisory board of Celgene, Janssen, Pfizer, and Roche; has received speakers honoraria from Celgene, Janseen, Mundipharma, Pfizer, and Roche; and receives support of academic studies (to the institution) from Celgene, Janssen, Mundipharma, Pfizer, and Roche. Dr. Brody reported no potential conflicts of interest.
EXPERT POINT OF VIEW
“P
atients are very excited about this new, well tolerated drug for chronic lymphocytic leukemia (CLL). Ibrutinib is available orally and is not chemotherapy. It produces excellent responses. This is particularly important for elderly [ie, age 65 and older] patients who are not always fit enough to withstand the chemotherapy regimens we use to treat younger patients. The drug is also particularly promising for high-risk patients such as those with abnormalities of TP53,” stated Claire Dearden, Claire Dearden, MD MD, moderator of a press conference at ASH. Dr. Dearden is Consultant Haematologist and Head of the Chronic Lymphocytic Leukaemia Unit at The Royal Marsden and The Institute of Cancer Research, and Medical Director of the South West London Cancer Network.
‘Welcome Advance’ If phase III studies validate the phase��������������������������������������� II������������������������������������ findings, ibrutinib will be considered a welcome advance, she continued. “At last, we could have our hands on an easy-to-take drug that may be very safe and effective in these patient groups for whom we haven’t previously had a good treatment. It would be a chemotherapy-free regimen as effective as chemotherapy,” she stated. “This is hugely exciting for us as clinicians and also for patients who are taking this drug. They feel better very quickly without many of the side effects of chemotherapy, other than diarrhea,” she stated. n Disclosure: Dr. Dearden reported no potential conflicts of interest.
have worse outcomes than low- and intermediate-risk patient, explained lead author Jan Burger MD, Associate Professor at The University of Texas MD Anderson Cancer Center in Houston. “This study shows profound activity for this combination in high-risk patients with CLL. The overall response rate is favorable compared with

standard treatment, and the toxicity compares favorably to other treatment options,” stated Dr. Burger. Patients were treated with ibrutinib at 420 mg/d combined with rituximab. High-risk criteria for entry included one of the following characteristics: deletion of 17p; TP53 mutation, deletion of 11q, or short (< 3 years) remission after first-line chemoimmunotherapy. No disease progression was observed in 95% of the entire group and
in 90% of those with 17p deletions ibrutinib achieved rapid reduction in the size of lymph nodes and spleen; 84% experienced > 50% decrease in lymph node size. As in the trial by Dr. Byrd and colleagues, treatment was well tolerated, with transient and infrequent grade 3/4 toxicities that included febrile neutropenia, anemia, mucositis, and pneumonia. n

sicians are rewarded for identifying and implementing best practices in an environment where evidence-based care was consistently used,” said Dr. Newcomer. He added that the balancing act would be to end the oncologist’s dependence on drug selection for practice survival while retaining present income levels. “The current system of oncology drug revenue dependence was created 40 years ago. No one thought it would be a problem, but it is, and it’s vital that we address ways to fix it,” he commented. “To reach that goal, we needed a performance measurement system with data. So, we asked physicians who entered the program to give us a single sheet of clinical information, including histology, stage, relevant genetics, and current status, which meant, for instance, that they needed to differentiate between an adjuvant patient and one who is relapsed with metastatic disease,” said Dr. Newcomer. He explained that the single-page format, combined with claims data, provided a comprehensive view of care by which they could create a fairly crude but effective longitudinal health record. “This allowed us to put patients in the right buckets and follow everything that happed to them in their cancer care experience. This information was collected in claims data, so we could harvest the outcomes and feed that back to the physicians,” said Dr. Newcomer.
The Program The first step in the program was to create episode categories. “We looked at patients with breast, lung, or colon
cancer and divided them into 24 different clinical scenarios. We had general agreement on the treatment strategies, but a lot of disagreement on the specifics,” said Dr. Newcomer. “Next, we found five large volunteer practice groups, all with strong clinical and business leaders. We asked the groups to pick the medical regimen they thought was best for each of the 24 clinical scenarios, with the understanding that once the group comes to consensus, every UnitedHealthcare patient in the episode program would be treated with the selected regimen unless they had a medical contraindi-
said Dr. Newcomer.
Incentivize Value, Not Margin “We took all of the margin that the groups used to make on selected drugs and called it a ‘patient care fee,’ which was paid in total—a bundled payment—on the first visit. So we gave the doctors a substantial upfront check. Going forward, as the drug regimens changed, we paid the practice for the cost of the drug, but the patient care fee didn’t change unless we saw an improvement in the outcomes data, or the total cost of treating these patients was lowered, in which case
I came out of this program feeling very optimistic, because I believe we’ve learned that improvement can be measured and costs can be reduced without sacrificing value. —Lee N. Newcomer, MD, MHA
cation,” commented Dr. Newcomer. He pointed out that the most important aspect of the program was for each of the five groups to be consistent with their treatment selections for the 24 clinical categories. “When you do things the same way, there is less complexity and error rates fall, which leads to scientific methods that systematically improve care. We could now track how well the therapies worked for these patients and compare the results among the five groups. The group leaders had to agree to meet annually to discuss and compare outcomes. The goal was to get consensus on what constituted a best practice,”
we shared a third of that savings with the group,” said Dr. Newcomer. They looked at total cost of care, survival, time to progression for the first regimen in metastatic disease, and hospital admissions for uncontrolled pain. After the data were collected, bar graphs were created to illustrate the results of each of the 24 clinical episodes, and the various measures were analyzed against the national group average to determine patterns of care. As an example, Dr. Newcomer looked at the average total cost per episode in the breast adjuvant setting. “Each of the five groups committed to treatment with TC [docetaxel/ cyclophosphamide], and the first
thing that struck us was the tremendous variation in drug costs. Digging deeper, we found that only half of the patients actually received TC; the other half received a more costly regimen. So, here are medical groups committed to consistency, but they couldn’t get half their patients on the regimens they selected. The lesson is that at an operational level, this kind of behavior change is very hard to accomplish, but our project showed that it’s worth the effort,” stressed Dr. Newcomer.
We Have to Do Something “We have a sense of urgency because we have to figure out how to reduce our escalating costs and still deliver value. And our hope was that this program would begin putting in place quality measurements and the incentives to follow them,” said Dr. Newcomer. He noted that although the episode payment program exposed some of the hurdles that will need to be overcome, quality measurement in oncology is possible and minimal clinical data are required to begin a program. “Payer-provider collaboration is a win/win situation because we both learn from the discussions about value. There are a lot of bumps in the road ahead, especially if practices are dealing with smaller payers who don’t have the resources and data capture ability of UnitedHealthcare. However, I came out of this program feeling very optimistic, because I believe we’ve learned that improvement can be measured and costs can be reduced without sacrificing value,” concluded Dr. Newcomer. n

Measuring and Improving Quality in Oncology Practices By Ronald Piana
T
he seed for ASCO’s Quality Oncology Practice Initiative (QOPI®) was planted a decade ago by Joseph Simone, MD, when he contemplated the feasibility of studying a volunteer group of oncologists to measure the quality of care they provide and share those results with their colleagues. Dr. Simone’s original vision has since grown far beyond its original scope. At ASCO’s first Quality Care Symposium in San Diego, Michael N. Neuss, MD, Chair of ASCO’s QOPI steering committee,
discussed the program’s first 5 years of data. Dr. Neuss is Chief Medical Officer and Professor of Clinical Medicine at Vanderbilt-Ingram Cancer Center, Nashville, Tennessee.
Biannual Analysis “Our project was geared to identify which factors in the QOPI project correlated with improvement—whether related to practice or measures—and to see if, in fact, practices improved over time,” said Dr. Neuss, mentioning that the QOPI self-reporting program
is analyzed twice a year. “There have been approximately 50 quality measures that were stable during the first 5 years of QOPI, and we used those measures for this analysis, which included 308 practices and approximately 2,000 physicians, representing about 15% of the nation’s medical oncology workforce,” explained Dr. Neuss. The overall quality scores were constructed based on questions from different domains, such as breast cancer, end-of-life care, colon and rectal
cancers, non–small cell lung cancer, non-Hodgkin lymphoma, and symptom toxicity management. “If we look at multivariate analysis in those factors associated with improvement, the highest correlations were seen for a new clinical practice, such as the introduction of a treatment drug or a genetic test associated with a drug. And when we looked at the interaction at the new practice over time, it showed the largest corollary of improvement within any variable within our measure continued on page 26

Important Safety Information Cutaneous squamous cell carcinoma (cuSCC) The incidence of cuSCC, including both SCCs of the skin and keratoacanthomas, was 24%. Perform dermatologic evaluations prior to initiation of therapy, every 2 months while on therapy, and potentially for 6 months after therapy. Any suspicious skin lesions should be excised, evaluated, and treated as per standard of care. Hypersensitivity and Dermatologic Reactions Serious hypersensitivity reactions, including anaphylaxis, generalized rash and erythema, or hypotension, have been reported in association with ZELBORAF and upon re-initiation of treatment. Severe dermatologic reactions, including Stevens-Johnson syndrome and toxic epidermal necrolysis, have been reported. In patients who experience a severe hypersensitivity or dermatologic reaction, ZELBORAF treatment should be permanently discontinued. QT prolongation Exposure-dependent QT prolongation has been reported, which may lead to an increased risk for ventricular arrhythmias, including Torsade de Pointes. Treatment is not recommended in patients with uncorrectable electrolyte abnormalities, with long QT syndrome, or who are taking medicines known to prolong the QT interval.
Monitor ECG and electrolytes before treatment and after dose modification. Monitor ECGs at day 15, monthly during the first 3 months of treatment, every 3 months thereafter, or more often as clinically indicated. If the QTc exceeds 500 ms, temporarily interrupt ZELBORAF, correct electrolyte abnormalities, and control cardiac risk factors for QT prolongation. Re-initiate treatment at a lower dose once the QTc decreases below 500 ms. Permanent discontinuation is recommended if, after correction of associated risk factors, the QTc increase meets both a value of >500 ms and >60 ms change from pre-treatment values. Liver laboratory abnormalities Liver laboratory abnormalities have occurred. Monitor liver enzymes 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. Photosensitivity Mild to severe photosensitivity has been reported. Advise patients to avoid sun exposure and use adequate sun protection. For intolerable grade 2 or greater photosensitivity, dose modifications are recommended. Ophthalmologic Reactions Serious ophthalmologic reactions, including uveitis and retinal vein occlusion, have been reported. Treatment with steroid and mydriatic ophthalmic drops may be required to manage uveitis. Routinely monitor patients for uveitis.

set,” said Dr. Neuss. According to the group’s findings, measures seemed to fall into three distinct areas: those that showed great improvement over time, those that showed no improvement because they were already too high to
improve, and those that showed no improvement despite a large opportunity to improve. “Although we saw a wide variation in baseline achievement among the practices that obscures any statistical significance to these measures [outside of the study model], I think that the underlying reality is a nice trend in improvement,”
said Dr. Neuss. Dr. Neuss next looked at whether adjuvant therapy in breast, colon, and non–small cell lung cancer was appropriately recommended to patients in the large data sets. “The level of achievement was very high, indicating that practices are doing very well in this setting.

ZELBORAF ® (vemurafenib) tablet, oral Initial U.S. Approval: 2011 This is a brief summary of information about ZELBORAF. Before prescribing, please refer to the full Prescribing Information. 1 INDICATIONS AND USAGE ZELBORAF ® is indicated for the treatment of patients with unresectable or metastatic melanoma with BRAF V600E mutation as detected by an FDA-approved test. Limitation of Use: ZELBORAF is not recommended for use in patients with wild-type BRAF melanoma. 5 WARNINGS AND PRECAUTIONS 5.1 Cutaneous Squamous Cell Carcinoma (cuSCC) Cases of cuSCC, including both SCCs of the skin and keratoacanthomas, have been reported in patients treated with ZELBORAF [see Adverse Reactions (6.1)]. The incidence of cuSCC in ZELBORAF-treated patients in Trial 1 was 24%. CuSCC usually occurred early in the course of treatment with a median time to the first appearance of 7 to 8 weeks. Of the patients who experienced cuSCC, approximately 33% experienced > 1 occurrence with median time between occurrences of 6 weeks. Potential risk factors associated with cuSCC in ZELBORAF clinical studies included age (≥ 65 years), prior skin cancer, and chronic sun exposure. In the clinical trials, cases of cuSCC were managed with excision, and patients were able to continue treatment without dose adjustment. It is recommended that all patients receive a dermatologic evaluation prior to initiation of therapy and every two months while on therapy. Any suspicious skin lesions should be excised, sent for dermatopathologic evaluation and treated as per standard of care. Monitoring should be considered for 6 months following discontinuation of ZELBORAF. 5.2 Hypersensitivity Reactions Serious hypersensitivity reactions, including anaphylaxis, have been reported in association with ZELBORAF and upon re-initiation of treatment. Severe hypersensitivity reactions included generalized rash and erythema or hypotension. In patients who experience a severe hypersensitivity reaction, ZELBORAF treatment should be permanently discontinued. 5.3 Dermatologic Reactions Severe dermatologic reactions have been reported in patients receiving ZELBORAF, including one case of Stevens-Johnson syndrome and one case of toxic epidermal necrolysis in Trial 1. In patients who experience a severe dermatologic reaction, ZELBORAF treatment should be permanently discontinued. 5.4 QT Prolongation Exposure-dependent QT prolongation was observed in an uncontrolled, open-label Phase 2 QT sub-study in previously treated patients with BRAF V600E mutation-positive metastatic melanoma [see Clinical Pharmacology (12.3)]. QT prolongation may lead to an increased risk of ventricular arrhythmias, including Torsade de Pointes. Treatment with ZELBORAF is not recommended in patients with uncorrectable electrolyte abnormalities, long QT syndrome, or who are taking medicinal products known to prolong the QT interval. ECG and electrolytes, including potassium, magnesium, and calcium, should be monitored before treatment with ZELBORAF and after dose modification. Monitoring of ECGs should occur 15 days after treatment initiation and then monthly during the first 3 months of treatment, followed by every 3 months thereafter or more often as clinically indicated. Initiation of treatment with ZELBORAF is not recommended in patients with QTc > 500 ms. If during treatment the QTc exceeds 500 ms (CTC-AE ≥ Grade 3), ZELBORAF treatment should be temporarily interrupted, electrolyte abnormalities should be corrected, and cardiac risk factors for QT prolongation (e.g., congestive heart failure, bradyarrhythmias) should be controlled. Re-initiation of treatment should occur at a lower dose once the QTc decreases below 500 ms [see Dosage and Administration (2.2)]. Permanent discontinuation of ZELBORAF treatment is recommended if after correction of associated risk factors, the QTc increase meets values of both > 500 ms and > 60 ms change from pre-treatment values. 5.5 Liver Laboratory Abnormalities Liver laboratory abnormalities have occurred with ZELBORAF (Table 3) [see Adverse Reactions (6.1)]. Liver enzymes (transaminases and alkaline phosphatase) and bilirubin should be monitored before initiation of treatment and monthly during treatment, or as clinically indicated. Laboratory abnormalities should be managed with dose reduction, treatment interruption, or treatment discontinuation [see Dosage and Administration (2.2)]. 5.6 Photosensitivity Mild to severe photosensitivity was reported in patients treated with ZELBORAF in clinical trials [see Adverse Reactions (6.1)]. All patients should be advised to avoid sun exposure while taking ZELBORAF. While taking the drug, patients should be advised to wear protective clothing and use a broad spectrum UVA/UVB sunscreen and lip balm (SPF ≥ 30) when outdoors to help protect against sunburn. For intolerable grade 2 (tender erythema covering 10 - 30% body surface area) or greater photosensitivity, dose modifications are recommended [see Dosage and Administration (2.2)]. 5.7 Ophthalmologic Reactions In Trial 1, five cases of uveitis have been reported in patients treated with ZELBORAF. Treatment with steroid and mydriatic ophthalmic drops may be required to manage uveitis. Patients should be routinely monitored for signs and symptoms of uveitis. Additionally, there were five patients with blurry vision, five patients with iritis and six patients with photophobia. There was one case of retinal vein occlusion in Trial 2. 5.8 New Primary Malignant Melanoma There were eight skin lesions in seven patients reported as new primary malignant melanoma in Trial 1. Cases were managed with excision, and patients continued treatment without dose adjustment. Monitoring for skin lesions should occur as outlined above [see Warnings and Precautions (5.1)]. 5.9 Use in Pregnancy Pregnancy Category D ZELBORAF may 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)]. 5.10 BRAF V600E Testing Confirmation of BRAF V600E mutation-positive melanoma as detected by an FDA-approved test is required for selection of patients for ZELBORAF therapy because these are the only patients studied and for whom benefit has been shown. For patients in ZELBORAF clinical studies, including Trial 1 and Trial 2, all enrolled patients tested positive when their tumor tissue was assessed with the cobas ® 4800 BRAF V600 Mutation Test [see Clinical Studies (14)]. This test is designed to detect BRAF V600E mutations in DNA isolated from formalin-fixed, paraffin-embedded
human melanoma tissue. The safety and efficacy of ZELBORAF have not been evaluated in patients whose melanoma tested negative by the cobas ® 4800 BRAF V600 Mutation Test. Refer to the package inserts of FDA approved test kits,for detailed information. 6 ADVERSE REACTIONS 6.1 Clinical Trials Experience Because clinical studies are conducted under widely varying conditions, adverse reaction rates observed in the clinical studies of a drug cannot be directly compared to rates in the clinical studies of another drug and may not predict the rates observed in a broader patient population in clinical practice. The adverse drug reactions (ADRs) described in this section were identified from Trial 1 and Trial 2 [see Clinical Studies (14)]. In Trial 1, treatment naive patients with unresectable or metastatic melanoma (n=675) were allocated to ZELBORAF 960 mg orally twice daily or to dacarbazine 1000 mg/m2 intravenously every 3 weeks. In Trial 2, (n=132) patients with metastatic melanoma and failure of at least one prior systemic therapy received treatment with ZELBORAF 960 mg orally twice daily. Adverse reactions reported in at least 10% of patients treated with ZELBORAF are presented in Table 2. The most common adverse reactions of any grade (≥ 30% in either study) reported in ZELBORAF-treated patients were arthralgia, rash, alopecia, fatigue, photosensitivity reaction, nausea, pruritus and skin papilloma. The most common (≥ 5%) Grade 3 adverse reactions were cuSCC and rash. The incidence of Grade 4 adverse reactions was ≤ 4% in both studies. The incidence of adverse events resulting in permanent discontinuation of study medication in Trial 1 was 7% for the ZELBORAF arm and 4% for the dacarbazine arm. In Trial 2, the incidence of adverse events resulting in permanent discontinuation of study medication was 3% in ZELBORAF-treated patients. The median duration of study treatment was 4.2 months for ZELBORAF and 0.8 months for dacarbazine in Trial 1, and 5.7 months for ZELBORAF in Trial 2.
Clinically relevant adverse events reported in < 10% of patients treated with ZELBORAF in the Phase 2 and Phase 3 studies include: Skin and subcutaneous tissue disorders: palmar-plantar erythrodysaesthesia syndrome, keratosis pilaris, erythema nodosum, Stevens-Johnson syndrome Musculoskeletal and connective tissue disorders: arthritis Nervous system disorders: dizziness, neuropathy peripheral, VII th nerve paralysis Neoplasms benign, malignant and unspecified (includes cysts and polyps): basal cell carcinoma Infections and infestations: folliculitis Investigations: weight decreased Eye disorders: retinal vein occlusion, uveitis Vascular disorders: vasculitis Cardiac disorders: atrial fibrillation Table 3 shows the incidence of worsening liver laboratory abnormalities in Trial 1 summarized as the proportion of patients who experienced a shift from baseline to Grade 3 or 4.

baseline achievement is more than 90%,” commented Dr. Neuss.
More Work to Be Done “The news is not as encouraging for measures such as the appropriate documentation of smoking cessation status, the risk of infertility, and fertility preservation in patients for whom these evidence-based measures would be applicable. As we know, measuring smoking is a ‘meaningful use’ criterion, and practices do very well in documenting tobacco use. However, we see that only 20% to 30% of the time, practices make an attempt to get their patients to quit smoking,” said Dr. Neuss. He added that there is a similar pattern of poor compliance in discussing fertility preservation options with patients with cancer who are of childbearing age. Dr. Neuss continued, “Because of the very varied initial attainment levels, we constructed a model to look at the overall achievement when normalized for baseline accomplishment. We saw that adjusted mean quality scores improved from 71% to 85%, which is significant. Also, when we looked at how the introduction of new measures did over time, we saw a very dramatic improvement,” noted Dr. Neuss. Indeed, the improvement over time was highly statistically significant (P < .0001). continued on page 27

2012 Quality Care Symposium ASCO’s Approach to Health Information Technology and the Rapid-learning System By Ronald Piana
LinQ’s core is the ability to measure quality in the oncology practice, measure outcomes, report in real time, and provide new methods of data exploration and hypothesis generation. “The real-time collection of quality and outcomes will allow the system to learn and improve the care of cancer patients by driving higher value and better outcomes,” said Dr. Lichter.
Rapid-learning System Allen S. Lichter, MD
T
he slow, but inevitable evolution of electronic oncology healthcare systems has already, at least conceptually, moved to the next generation of machines that not only store and process data, but also have the ability to provide real-time clinical decision support. At ASCO’s first Quality Care Symposium in San Diego, ASCO CEO Allen S. Lichter, MD, unveiled the Society’s ambitious addition to the evolution of the rapid-learning system.
Paving the Way Forward “It’s my pleasure to launch the maiden voyage of ASCO’s contribution to the rapid-learning system, CancerLinQ. The idea of a rapid-learning system has been floating around for a long time. The Institute of Medicine [IOM] has dedicated an unprecedented amount of its attention to this idea, which culminated in a monumental report on the earning health-care system. The report gave rationale, data, and specific recommendations on how to move forward. ASCO has embraced the vision outlined by the IOM and others, and that’s the origin of CancerLinQ, the next evolution of our quality programs,” said Dr. Lichter. Dr. Lichter explained that Cancer-

“Although very complex, the core of the rapid-learning system is a circle that is really a classic feedforwardfeedback cycle of quality improvement. It begins at the point of care where the data are collected by computer, transformed, and aggregated; then the data are analyzed and services are provided in compliance with important measures,” said Dr. Lichter. The system, explained Dr. Lichter, has a second cycle attached to it. “Once the data are analyzed, it can go through peer review and feedback, generate

The Prototype After laying the foundation by engaging leaders in the oncology community, hammering out a business plan, and doing the legal and technology analysis, ASCO’s work on the prototype system began. Dr. Lichter said that the group set out to construct the prototype with five goals: 1. Provide “lessons learned about the technological and logistical challenges of a full-scale implementation of CancerLinQ 2. Demonstrate value-added tools, such as the ability to measure a clinician’s performance on a subset of the Quality Oncology Practice Initiative (QOPI®) in real time

new hypotheses, and do correlation and trend analysis. That second process begins to make our guidelines and guidance better,” said Dr. Lichter. “Right now, as in most medical specialties, the majority of things we do are based on consensus or good solid hunches, not on level 1 clinical trial evidence. In fact, there are so many decision points in oncology that we

thorne effect is that behavior during the course of a study may be the result of social situations and the subjects’ awareness that they are being observed.) “I would submit to you that the workers got better because they were made into a team instead of individuals. And the lesson here is that when practitioners and their patients work as a team, they improve quality care together,” said Dr. Neuss.
Lessons Learned So Far Dr. Neuss stressed that medical oncology practices have improved in some but not all measures of care, and though improvement is rapid for many measures, those with the greatest improvement are the ones measuring the adoption of new information or treatments. “On many of the adjuvant treatments, it appears that QOPI partici-
and make use of the data. “After taking the key points from the original feedforward-feedback cycle, we built a rather crude oncology [electronic health record system] from an open-source [electronic health record] so we could interact with the system and develop batch filing and processing of data. In other words, we developed automatic processing so we were able to understand the data that were being sent to us from various aggregates of medical records,” commented Dr. Lichter.
Analytic Component Using an elegant visual platform called Galileo Cosmos™, Dr. Lichter demonstrated a drag-and-drop feature that allows the user to enter all pertinent clinical information about a particular patient and screen See Page 101 the information against a particular regimen. The program graphically illustrates the various outcomes in a multiplicity of clinical scenarios. Dr. Lichter toggled back and forth, visually comparing and contrasting the outcomes of different agents. “With this kind of data capture, we can begin to show and analyze outcomes and answer interesting and complex clinical questions in real time,” said Dr. Lichter. After showing multiple slides that explored the interactive capabilities of the prototype electronic medical record— from practice guidelines to adverse events—Dr. Lichter noted that many of the key nodal points in a learning health-care system are currently feasible. continued on page 28
pants are already doing well. However, measuring is not enough. We have to improve our care by using collaborative models. To that end, networks have spontaneously sprung up within the QOPI practices…. [P]ayers have been very supportive of these important quality initiatives—QOPI is truly a collaborative effort with downstream benefits for our patients,” concluded Dr. Neuss. n

2012 Quality Care Symposium Developing Cancer Care Pathways for the New Environment By Ronald Piana
A
s community practices and the insurance industry seek cost-effective ways to adapt to the Patient Protection and Affordable Care Act, the evolving concept of cancer care pathways is emerging as a strategy that may help control oncology costs and add value to care. At ASCO’s recent Quality Care Symposium in San Diego, Peter G. Ellis, MD, Director of Medical Oncology Network for the University of Pittsburgh Medical Center (UPMC) Cancer Center, discussed his institution’s experience with cancer care pathways. Dr. Ellis explained that UPMC Cancer Center is a distinct product line of UPMC, which is a not-for-profit health system that provides health services and insurance coverage in Western Pennsylvania. “After developing a cancer care delivery system across a large network of academic and community sites, we wondered what kind of quality we have. So we sent out surveys of five case studies to all of our providers, asking them how they would handle each clinical issue, and we got back 25 different answers,” said Dr. Ellis. He added, “we sought to assess the quality of our delivery system and develop cancer care pathways to drive standardized care, lower costs, and increase trial accrual. It was a forward-thinking idea for 2004, almost a decade ago.”
Why Pathways Now? Pathways made sense then, Dr. Ellis noted, but “why do we need them now?” he asked. He continued, “We still need the benefits of standardized care, but now we also have to prepare for health-care reform that will usher in the new era of medical homes and accountable care organizations. We also need to have the ability for reporting our outcomes to our value-conscious consumers and to facilitate practicehospital comanagement relationships. Moreover, pathways may also be used to aggregate large networks of physicians under clinically integrated sys-

Work in Progress
Stressing that CancerLinQ is still very much a work in progress, Dr. Lichter said, “We have learned about the technological and logisti-
tems and make sure that they have the latest clinical information at point of service,” said Dr. Ellis.

The Pathway Process “To begin our pathways development process, we set up disease-specific committees, in which we asked for volunteer co-chairs to lead each committee. On each committee, one chair was an academician and one was community based—the chairs were selected for their expertise in the treatment of that specific disease,” commented Dr. Ellis. The initial goal of the committees was to define the states and stages of disease for which a treatment is needed, and to define common comorbidities that would commonly occur and be likely to demand alternative therapies. “The overriding goal was to de-

tees meet quarterly via webinar. We first review any conflict of interest disclosures that may influence decisions. Then we review new evidence and debate that evidence until consensus is established for possible changes to the pathway,” he said. Dr. Ellis stressed that there are sig-

way to get practices on board with pathways is to be honest and emphasize their proven value in reducing medical errors, improving patient outcomes, driving practice efficiencies, and measuring success,” said Dr. Ellis. He added that it’s important to mention the emergence of accountable care organizations and medical homes as key drivers of patient referrals. “And of course, make sure they know it’s okay to go ‘off pathway,’” said Dr. Ellis. “Finally,” he emphasized, “you need to make this tool easy to use! You cannot expect doctors to adopt a system that is burdensome on their already overtaxed practice. Imbed the pathways in a convenient point-of-care decision support tool that helps physicians select treatments. Hopefully, practices will be able to integrate the pathways into their current flow, either as a stand-alone tool or with their electronic medical records,” said Dr. Ellis. “Challenges aside, we are in a changing practice environment, and effective pathway programs drive standardization across multiple sites for numerous physicians, increasing adherence to increasingly complex evidence-based medicine. Properly implemented, pathways improve practice efficiency and conserve health-care resources, which is a vital component for today’s oncology practices,” concluded Dr. Ellis. n
fine therapies for 80% of our patients. We are not going to have pathways that apply to all the patients who walk in our doors. There is art to what we do, and although not all patients will fit into the pathways, we feel that the 80% who do will benefit from reductions in unwarranted variation in care that we see,” said Dr. Ellis. The committees collect and review all relevant published clinical literature and determine a single best recommendation for each state, stage, and presentation of disease including common comorbidities, based on a threetier process of efficacy, toxicity, and cost. “These are living documents that need to be maintained, so the commit-
nificant challenges to developing and initiating clinical pathways. “It seems like a pretty straightforward process, but it isn’t. For instance, there is a lack of head-to-head data for many of the regimens, and assigning worth to very expensive new drugs that have marginally improved outcomes becomes a difficult task. Also, the need to drive standardization via consensus where there are no clear data can be a challenge create an obstacle to the pathways,” said Dr. Ellis. According to Dr. Ellis, the benefits of clinical pathways outweigh the challenges of implementation. “The best

• In untreated patients whose Hb fell below 10 g/dL, 1 in 3 required an RBC transfusion within 6 weeks*5 • Aranesp® significantly reduced the need for RBC transfusions by 48% compared to placebo†2,3 • Aranesp® can be synchronized with the majority of chemotherapy regimens, including Q3W6 * Data from an exploratory, pooled analysis performed on a subset of placebo-treated patients (N = 411) from 6 randomized darbepoetin alfa CIA trials. Patients had baseline Hb ≥ 10 g/dL and decline to Hb < 10 g/dL at least once during the study-treatment period. Kaplan-Meier (K-M) estimates were calculated for the incidence of patients with transfusions by Weeks 0, 3, 6, and 9 after Hb < 10 g/dL was reached. Seventy-two percent of patients had lung cancer.5 †Data from a randomized, double-blind, placebo-controlled trial of 314 anemic (Hb ≤ 11 g/dL) patients with lung cancer receiving platinum-containing chemotherapy. Patients received once-weekly treatment with either Aranesp® (2.25 mcg/kg) or placebo, administered by subcutaneous injection, for up to 12 weeks. Per the pivotal trial protocol, doses were withheld if Hb exceeded 14 g/dL for women or 15 g/dL for men.3
INDICATION and LIMITATIONS OF USE Aranesp® (darbepoetin alfa) is for the treatment of anemia in patients with non-myeloid malignancies where anemia is due to the effect of concomitant myelosuppressive chemotherapy, and upon initiation, there is a minimum of two additional months of planned chemotherapy. Aranesp® is not for use: • In patients receiving hormonal agents, biologic products, or radiotherapy, unless also receiving concomitant myelosuppressive chemotherapy • In patients receiving myelosuppressive chemotherapy when the anticipated outcome is cure • As a substitute for RBC transfusions in patients requiring immediate correction of anemia Aranesp® has not been shown to improve quality of life, fatigue, or patient well-being.

Tumor Grade Is Associated with Risk for Venous Thromboembolism By Matthew Stenger
R
ecent data suggest that risk for venous thromboembolism is associated with biologic aggressiveness of cancer. Findings in the Vienna Cancer and Thrombosis Study, recently reported by Ahlbrecht and colleagues in Journal of Clinical Oncology, indicate that patients with higher-grade tumors are at significantly increased risk of venous thromboembolism.1 Further, tumor grade was found to be associated with changes in levels of Ddimer, leukocytes, and hemoglobin— biomarkers that have also been linked with venous thromboembolism risk.
Study Details

In the study, 747 patients with newly diagnosed solid tumors or progression of disease after remission were followed for a median of 526 days for occurrence of symptomatic and objectively confirmed venous thromboembolism. Patients were not routinely screened for the disease. Accidentally detected thrombotic events were counted as venous thromboembolism events if they were considered clinically significant by the study adjudication committee. Patients had a median age of 63 years, and 54% were male. Sites of cancer included lung in 20.3%, breast in 19.1%, colorectal in 17.4%, prostate in 17.4%, pancreas in 8.8%, stomach in 6.7%, kidney in 4.6%, and “other” in 5.8%. For tumor grade, a three-level grading system (grades 1 to 3) was used for breast and prostate cancer, and a four-level system was used for other cancers. Overall, 62.7% of patients had low-grade tumors (7.0% grade 1 and 55.7% grade 2) and 37.3% had high-grade tumors (35.7% grade 3 and 1.6% grade 4). Disease was localized in 49.0% and consisted of distant metastasis in 50.5%. Histology consisted of adenocarcinoma in 83.5% of patients and nonadenocarcinoma in 16.1%, primarily squamous cell carcinoma of various sites, renal clear cell carcinoma, and small cell lung cancer. During the study peri-
od, 46.9% of patients received surgery, 66.1% received chemotherapy, and 44.8% received radiotherapy. During up to 2 years of follow-up, 282 patients (37.8%) died without clear evidence of venous thromboembolism. Objectively confirmed venous thromboembolism occurred in 52 patients (7.0%), including asymptomatic disease in 11. The cumulative probability of venous thromboembolism in the entire population was 5.5% after 6 months and 6.2% after 1 year.
cinoma vs nonadenocarcinoma) and tumor sites (high-risk vs low-risk); sites considered to pose high risk for venous thromboembolism were the pancreas, gastrointestinal system, lung, and kidney, and low-risk sites were the breast, prostate, and “other” sites. On this analysis, high-grade tumors were associated with a significant twofold increased risk of venous thromboembolism (HR = 2.0, 95% CI = 1.1–3.5, P = .015). A similar outcome was found in a
Tumor grade is a routine parameter available for almost all solid tumor types and thus represents an easy tool for risk assessment of cancer-associated venous thromboembolism. Of all venous thromboembolism events, most were either isolated deep-vein thrombosis of the lower extremity (36.5%) or isolated pulmonary embolism (36.5%). By cancer site, 26.9% of events occurred in patients with pancreas cancer, 23.1% in those with colorectal cancer, 17.3% in those with stomach cancer, 15.4% in those with lung cancer, and 5.8% each in those with prostate, breast, and other cancer sites.
High-grade Tumors Predict Increased Risk Overall, 51.9% of venous thromboembolism events occurred in patients with low-grade tumors (5.8% in those with grade 1 and 46.2% in those with grade 2) and 48.1% occurred in those with high-grade tumors (46.2% in those with grade 3 and 1.9% in those with grade 4). On univariate analysis, patients with high-grade tumors had a significant 80% increase in risk for venous thromboembolism (hazard ratio [HR] = 1.8, 95% confidence interval [CI] = 1.0–3.1, P = .04). A multivariate model adjusted for distant metastasis, sex, age, and interaction between histology (adenocar-

second multivariate model including distant metastasis, interaction between histology and tumor sites, and treatment (surgery, chemotherapy, and radiotherapy), with high-grade tumors being associated with a 90% increased risk of venous thromboembolism (HR = 1.9, 95% CI = 1.1–3.3, P = .023). On KaplanMeier analysis, the cumulative probability of venous thromboembolism after 6 months was 8.2% in patients with highgrade tumors vs 4.0% in those with lowgrade tumors (P = .037).
Tumor Grade and Biomarkers High-grade tumors were associated with differences in some of the biomarkers previously reported to be predictive of venous thromboembolism. Patients with high-grade tumors had significantly higher median D-dimer levels (0.78 vs 0.64 µg/ mL, P = .008) and leukocyte counts <��������������� �������������� .001) and sig(7.5 vs 6.8 × 109/L, P ���������������� nificantly lower median hemoglobin levels (12.9 vs 13.2 g/dL, P = .008). There were no differences between patients with high-grade tumors and those with low-grade tumors with regard to other biomarkers, including prothrombin fragment 1 + 2, sPselectin, clotting factor VIII activity, and platelet count. A third multivariate model included the independent variables from the first two models (ie, tumor grade, histology, and tumor sites) and the biomarkers D-dimer, hemoglobin, platelet count, and leukocyte count—all routinely
available clinical or laboratory variables. On this model, the adjusted hazard ratio for venous thromboembolism for high-grade tumors was 1.9 (95% CI = 1.1–3.3, P = .023). Also independently associated with venous thromboembolism were high-risk tumor sites (HR = <������������ ����������� .001), ade4.3, 95% CI = 2.1–9.0, P ������������� nocarcinoma histology (HR = 2.7, 95% CI = 1.1–6.9, P = .038), and D-dimer level greater than 1.32 µg/mL (75% percentile of the population; HR = 2.2, 95% CI = 1.3–3.9, P = .005). The findings in this study suggest that tumor differentiation may play an important role in the development of cancer-related venous thromboembolism. As stated by the investigators, “Tumor grade is a routine parameter available for almost all solid tumor types and thus represents an easy tool for risk assessment of cancer-associated [venous thromboembolism]. Because thromboprophylaxis … is still a major challenge, it may be useful to incorporate the tumor grade in risk assessment models…. This could enable improved assessment of the [venous thromboembolism] risk in the heterogeneous population of patients with cancer.” n See Page 101

Fixed-dose Apixaban Reduces Risk of Recurrent Venous Thromboembolism By Alice Goodman
V
enous thromboembolism is a frequent problem in cancer patients, and approximately 20% of all patients who develop the disease have a recurrence. Extending treatment with two fixed doses of the investigational agent apixaban, a factor Xa inhibitor without laboratory monitoring, may provide a simple, effective, and safe strategy for long-term management of venous thromboembolism, according to a study presented at the 54th Annual Meeting of the American Society of Hematology in Atlanta.1
Acceptable Safety “Both doses of anticoagulant reduced the risk of recurrent venous thromboembolism by about 80%. The rates of major bleeding were low and comparable to those in the placebo group,” said lead author Giancarlo Agnelli, MD, Professor of Internal Medicine and Director of the Department of Internal and Cardiovascular Medicine and Stroke Unit at Perugia University Hospital in Perugia, Italy. “This regimen has the potential to eliminate many of the challenges we face when treating patients with warfarin, including drug and food interactions, and the need for ongoing monitoring, which can simplify ongoing management of this condition.”
Dr. Agnelli and coauthors calculated that the number of patients needed to treat to prevent 1 episode of recurrent or nonfatal venous thromboembolism is 14, which is low and acceptable, he said. On the other hand, the number of patients needed to treat to cause 1 episode of major or clinically relevant nonmajor bleeding is 200. The randomized, double-blind, placebo-controlled AMPLIFY-EXT study compared two doses of apixaban—2.5 mg and 5 mg—given as secondary prophylaxis vs placebo in patients with deep-vein thrombosis/venous thromboembolism who had completed 6 to 12 months of anticoagulant therapy. Patients were treated with apixaban for 12 months. Safety data were evaluated 30 days after treatment initiation.
Key Results The primary endpoint of symptomatic recurrent venous thromboembolism or all-cause death occurred in 3.8% of patients on the 2.5-mg dose and 4.2% on the 5 mg-dose vs 11.6% on placebo. Recurrent venous thromboembolism or thrombosis-related death was reported in 1.7% of patients on the 2.5mg dose, 1.7% on the 5-mg dose, and 8.8% of the placebo group. Recurrent thrombosis, thrombosis-related death, myocardial infarction, stroke, or cardio-
Extended Treatment of Venous Thromboembolism ■■ An investigational oral factor Xa inhibitor, apixaban, reduced the risk of
fatal and nonfatal venous thromboembolism by 80% in patients who have had 6 to 12 months of previous anticoagulant therapy.
■■ No monitoring is necessary with this agent, and treatment is minimally dependent on renal clearance.
■■ Apixaban is being reviewed by FDA.
EXPERT POINT OF VIEW
P
ress conference moderator Agnes Y. Lee, MD, Medical Director of the Thrombosis Program and Associate Professor of Medicine at the University of British Columbia and Vancouver Coastal Health in Canada, said that apixaban is the third in a new line of anticoagulants for long-term prevention of thrombotic events. “This is an important trial showing that apixaban is highly effective and safe for long-term treatment of venous thromboembolism. By contrast with dabigaAgnes Y. Lee, MD tran [Pradaxa] and rivaroxaban [Xarelto], the other two Xa inhibitors, apixaban therapy is minimally dependent (< 20%) on renal clearance. This gives us another therapeutic option and it is suitable for patients with moderate renal impairment,” Dr. Lee continued. “More options are better so we can personalize therapy for our patients. This study shows how we can improve patient outcomes by conducting rigorous randomized trials,” she said. Nevertheless, it’s important to point out that the study included only 42 patients with cancer, Dr. Lee told The ASCO Post. “The results might not apply to patients with cancer, who have a higher risk of treatment failure with anticoagulants than patients without cancer. Also, there are chemotherapeutic agents that do interact with this drug’s clearance mechanisms, raising a concern that therapeutic drug levels might not be achieved if patients are receiving certain chemotherapeutic drugs.” n Disclosure: Dr. Lee reported no potential conflicts of interest.
vascular-related deaths were reported in 2.1% of the 2.5-mg group, 2.3% of the 5-mg group, and 10% of placebo patients. “Both doses of apixaban reduced the risk of recurrent [venous thromboembolism and venous thromboembolism–related] death by 80%,” Dr. Agnelli stated. The rates of major bleeding associated with both doses of apixaban were similar to placebo: 0.2% with 2.5 mg, 0.1% with 5 mg, and 0.5% with placebo. These data will be part of the submission package to the FDA, but have not yet been submitted, he noted.
The optimal duration of treatment with apixaban is not yet established. In this study, 1 year of treatment achieved risk reduction in venous thromboembolism without increased risk of major bleeding. n
Disclosure: Dr. Agnelli reported no potential conflicts of interest.

ABRAXANE® for Injectable Suspension (paclitaxel protein-bound particles for injectable suspension) (albumin-bound) is indicated for the treatment of breast cancer after failure of combination chemotherapy for metastatic disease or relapse within 6 months of adjuvant chemotherapy. Prior therapy should have included an anthracycline unless clinically contraindicated. ABRAXANE is indicated for the first-line treatment of locally advanced or metastatic non–small cell lung cancer, in combination with carboplatin, in patients who are not candidates for curative surgery or radiation therapy.
Important Safety Information WARNING - NEUTROPENIA • Do not administer ABRAXANE therapy to patients who have baseline neutrophil counts of less than 1,500 cells/mm3. In order to monitor the occurrence of bone marrow suppression, primarily neutropenia, which may be severe and result in infection, it is recommended that frequent peripheral blood cell counts be performed on all patients receiving ABRAXANE • Note: An albumin form of paclitaxel may substantially affect a drug’s functional properties relative to those of drug in solution. DO NOT SUBSTITUTE FOR OR WITH OTHER PACLITAXEL FORMULATIONS CONTRAINDICATIONS Neutrophil Counts • ABRAXANE should not be used in patients who have baseline neutrophil counts of <1,500 cells/mm3 Hypersensitivity • Patients who experience a severe hypersensitivity reaction to ABRAXANE should not be rechallenged with the drug WARNINGS AND PRECAUTIONS Hematologic Effects • Bone marrow suppression (primarily neutropenia) is dose-dependent and a dose-limiting toxicity of ABRAXANE • Monitor for myelotoxicity by performing complete blood cell counts frequently, including prior to dosing on Day 1 for metastatic breast cancer (MBC) and Days 1, 8, and 15 for non-small cell lung cancer (NSCLC) • Do not administer ABRAXANE to patients with baseline absolute neutrophil counts (ANC) of less than 1,500 cells/mm3 • In the case of severe neutropenia (<500 cells/mm3 for 7 days or more) during a course of ABRAXANE therapy, reduce the dose of ABRAXANE in subsequent courses in patients with either MBC or NSCLC • In patients with MBC, resume treatment with every-3-week cycles of ABRAXANE after ANC recovers to a level >1,500 cells/mm3 and platelets recover to >100,000 cells/mm3 • In patients with NSCLC, resume treatment if recommended at permanently reduced doses for both weekly ABRAXANE and every-3-week carboplatin after ANC recovers to at least 1,500 cells/mm3 and platelet count of at least 100,000 cells/mm3 on Day 1 or to an ANC of at least 500 cells/mm3 and platelet count of at least 50,000 cells/mm3 on Days 8 or 15 of the cycle Nervous System • Sensory neuropathy is dose- and schedule-dependent • The occurrence of Grade 1 or 2 sensory neuropathy does not generally require dose modification • If ≥ Grade 3 sensory neuropathy develops, treatment should be withheld until resolution to Grade 1 or 2 for MBC or until resolution to ≤ Grade 1 for NSCLC followed by a dose reduction for all subsequent courses of ABRAXANE Hypersensitivity • Severe and sometimes fatal hypersensitivity reactions, including anaphylactic reactions, have been reported • Patients who experience a severe hypersensitivity reaction to ABRAXANE should not be re-challenged with this drug Hepatic Impairment • Because the exposure and toxicity of paclitaxel can be increased with hepatic impairment, administration of ABRAXANE in patients with hepatic impairment should be performed with caution • The starting dose should be reduced for patients with moderate or severe hepatic impairment Albumin (Human) • ABRAXANE contains albumin (human), a derivative of human blood

ABRAXANE® for Injectable Suspension (paclitaxel protein-bound particles for injectable suspension) (albumin-bound) The following is a brief summary; refer to full prescribing information for complete product information. WARNING: NEUTROPENIA • Do not administer ABRAXANE therapy to patients who have baseline neutrophil counts of less than 1,500 cells/mm3. In order to monitor the occurrence of bone marrow suppression, primarily neutropenia, which may be severe and result in infection, it is recommended that frequent peripheral blood cell counts be performed on all patients receiving ABRAXANE [see Contraindications (4), Warnings and Precautions (5.1) and Adverse Reactions (6.1, 6.2)]. • Note: An albumin form of paclitaxel may substantially affect a drug’s functional properties relative to those of drug in solution. DO NOT SUBSTITUTE FOR OR WITH OTHER PACLITAXEL FORMULATIONS. 1 INDICATIONS AND USAGE 1.1 Metastatic Breast Cancer ABRAXANE is indicated for the treatment of breast cancer after failure of combination chemotherapy for metastatic disease or relapse within 6 months of adjuvant chemotherapy. Prior therapy should have included an anthracycline unless clinically contraindicated. 1.2 Non-Small Cell Lung Cancer ABRAXANE is indicated for the first-line treatment of locally advanced or metastatic non-small cell lung cancer, in combination with carboplatin, in patients who are not candidates for curative surgery or radiation therapy. 2 DOSAGE AND ADMINISTRATION 2.1 Metastatic Breast Cancer After failure of combination chemotherapy for metastatic breast cancer or relapse within 6 months of adjuvant chemotherapy, the recommended regimen for ABRAXANE is 260 mg/m2 administered intravenously over 30 minutes every 3 weeks. 2.2 Non-Small Cell Lung Cancer The recommended dose of ABRAXANE is 100 mg/m2 administered as an intravenous infusion over 30 minutes on Days 1, 8, and 15 of each 21-day cycle. The recommended dose of carboplatin is AUC = 6 mg•min/mL on Day 1 only of each 21-day cycle, beginning immediately after the completion of ABRAXANE administration. 2.3 Dosage in Patients with Hepatic Impairment No dose adjustment is necessary for patients with mild hepatic impairment. Patients with moderate and severe hepatic impairment treated with ABRAXANE may be at increased risk of toxicities known to paclitaxel. Withhold ABRAXANE if AST >10 x ULN or bilirubin > 5 x ULN. Recommendations for dosage adjustment for the first course of therapy are shown in Table 1. For metastatic breast cancer, the dose of ABRAXANE can be increased from 130 mg/m2 up to 200 mg/m2 in patients with severe hepatic impairment in subsequent cycles based on individual tolerance. For non-small cell lung cancer, reduce the dose of ABRAXANE to 50 mg/m2 in patients with severe hepatic impairment. In subsequent cycles, the dose of ABRAXANE may be increased to 75 mg/m2 as tolerated. Monitor patients closely [see Warnings and Precautions (5.4), Use in Specific Populations (8.6), and Clinical Pharmacology (12.3)]. Table 1: Recommendations for Starting Dose in Patients with Hepatic Impairment SGOT (AST) Bilirubin Levels ABRAXANE Dosea Levels MBC NSCLC Mild < 10 x ULN > ULN to ≤ 1.25 x ULN 260 mg/m2 100 mg/m2 Moderate < 10 x ULN AND 1.26 to 2 x ULN 200 mg/m2 75 mg/m2 Severe < 10 x ULN 2.01 to 5 x ULN 130 mg/m2 b 50 mg/m2 c > 10 x ULN OR > 5 x ULN not eligible not eligible MBC = Metastatic Breast Cancer; NSCLC = Non-Small Cell Lung Cancer. a Dosage recommendations are for the first course of therapy. The need for further dose adjustments in subsequent courses should be based on individual tolerance. b A dose increase to 200 mg/m2 in subsequent courses should be considered based on individual tolerance. c Increase dose to 75 mg/m2 in subsequent courses, as tolerated. 2.4 Dose Reduction/Discontinuation Recommendations Metastatic Breast Cancer Patients who experience severe neutropenia (neutrophil <500 cells/mm3 for a week or longer) or severe sensory neuropathy during ABRAXANE therapy should have dosage reduced to 220 mg/m2 for subsequent courses of ABRAXANE. For recurrence of severe neutropenia or severe sensory neuropathy, additional dose reduction should be made to 180 mg/m2. For Grade 3 sensory neuropathy hold treatment until resolution to
Grade 1 or 2, followed by a dose reduction for all subsequent courses of ABRAXANE [see Contraindications (4), Warnings and Precautions (5.1, 5.2) and Adverse Reactions (6.1)]. Non-Small Cell Lung Cancer • Do not administer ABRAXANE on Day 1 of a cycle until absolute neutrophil count (ANC) is at least 1500 cells/mm3 and platelet count is at least 100,000 cells/mm3 [see Contraindications (4),Warnings and Precautions (5.1) and Adverse Reactions (6.2)]. • In patients who develop severe neutropenia or thrombocytopenia withhold treatment until counts recover to an absolute neutrophil count of at least 1500 cells/mm3 and platelet count of at least 100,000 cells/mm3 on Day 1 or to an absolute neutrophil count of at least 500 cells/mm3 and platelet count of at least 50,000 cells/mm3 on Days 8 or 15 of the cycle. Upon resumption of dosing, permanently reduce ABRAXANE and carboplatin doses as outlined in Table 2. • Withhold ABRAXANE for Grade 3-4 peripheral neuropathy. Resume ABRAXANE and carboplatin at reduced doses (see Table 2) when peripheral neuropathy improves to Grade 1 or completely resolves [see Warnings and Precautions (5.2) and Adverse Reactions (6.2)]. Table 2: Permanent Dose Reductions for Hematologic and Neurologic Adverse Drug Reactions in NSCLC Weekly Every 3-Week Adverse Drug Reaction Occurrence ABRAXANE Dose Carboplatin Dose 2 (mg/m ) (AUC mg•min/mL) Neutropenic Fever (ANC less than 500/mm3 First 75 4.5 with fever >38°C) OR Delay of next cycle by more than 7 days for ANC Second 50 3 less than 1500/mm3 OR Third Discontinue Treatment ANC less than 500/mm3 for more than 7 days First 75 4.5 Platelet count less than 50,000/mm3 Second Discontinue Treatment First 75 4.5 Severe sensory Neuropathy – Second 50 3 Grade 3 or 4 Third Discontinue Treatment 4 CONTRAINDICATIONS • ABRAXANE should not be used in patients who have baseline neutrophil counts of < 1,500 cells/mm3. • Patients who experience a severe hypersensitivity reaction to ABRAXANE should not be rechallenged with the drug. 5 WARNINGS AND PRECAUTIONS 5.1 Hematologic Effects Bone marrow suppression (primarily neutropenia) is dose-dependent and a dose-limiting toxicity of ABRAXANE. In clinical studies, Grade 3-4 neutropenia occurred in 34% of patients with metastatic breast cancer (MBC) and 47% of patients with non-small cell lung cancer (NSCLC). Monitor for myelotoxicity by performing complete blood cell counts frequently, including prior to dosing on Day 1 (for MBC) and Days 1, 8, and 15 (for NSCLC). Do not administer ABRAXANE to patients with baseline absolute neutrophil counts (ANC) of less than 1,500 cells/mm3. In the case of severe neutropenia (<500 cells/mm3 for seven days or more) during a course of ABRAXANE therapy, reduce the dose of ABRAXANE in subsequent courses in patients with either MBC or NSCLC. In patients with MBC, resume treatment with every-3-week cycles of ABRAXANE after ANC recovers to a level >1,500 cells/mm3 and platelets recover to a level >100,000 cells/mm3. In patients with NSCLC, resume treatment if recommended (see Dosage and Administration, Table 2) at permanently reduced doses for both weekly ABRAXANE and every-3-week carboplatin after ANC recovers to at least 1500 cells/mm3 and platelet count of at least 100,000 cells/mm3 on Day 1 or to an ANC of at least 500 cells/mm3 and platelet count of at least 50,000 cells/mm3 on Days 8 or 15 of the cycle [see Dosage and Administration (2.4)]. 5.2 Nervous System Sensory neuropathy is dose- and schedule-dependent [see Adverse Reactions (6.1, 6.2)]. The occurrence of Grade 1 or 2 sensory neuropathy does not generally require dose modification. If ≥ Grade 3 sensory neuropathy develops, treatment should be withheld until resolution to Grade 1 or 2 for metastatic breast cancer or until resolution to ≤ Grade 1 for NSCLC followed by a dose reduction for all subsequent courses of ABRAXANE [see Dosage and Administration (2.4)]. 5.3 Hypersensitivity Severe and sometimes fatal hypersensitivity reactions, including anaphylactic reactions, have been reported. Patients who experience
a severe hypersensitivity reaction to ABRAXANE should not be re-challenged with this drug. 5.4 Hepatic Impairment Because the exposure and toxicity of paclitaxel can be increased with hepatic impairment, administration of ABRAXANE in patients with hepatic impairment should be performed with caution. The starting dose should be reduced for patients with moderate or severe hepatic impairment [see Dosage and Administration (2.3), Use in Specific Populations (8.6) and Clinical Pharmacology (12.3)]. 5.5 Albumin (Human) ABRAXANE contains albumin (human), a derivative of human blood. Based on effective donor screening and product manufacturing processes, it carries a remote risk for transmission of viral diseases. A theoretical risk for transmission of Creutzfeldt-Jakob Disease (CJD) also is considered extremely remote. No cases of transmission of viral diseases or CJD have ever been identified for albumin. 5.6 Use in Pregnancy ABRAXANE can cause fetal harm when administered to a pregnant woman. Administration of paclitaxel protein-bound particles to rats during pregnancy at doses lower than the maximum recommended human dose, based on body surface area, caused embryo-fetal toxicities, including intrauterine mortality, increased resorptions, reduced numbers of live fetuses, and malformations. There are no adequate and well-controlled studies in pregnant women receiving ABRAXANE. 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. Women of childbearing potential should be advised to avoid becoming pregnant while receiving ABRAXANE [see Use in Specific Populations (8.1)]. 5.7 Use in Men Men should be advised not to father a child while receiving ABRAXANE [see Nonclinical Toxicology (13.1)]. 6 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 practice. The most common adverse reactions (â&#x2030;Ľ 20%) with single-agent use of ABRAXANE in metastatic breast cancer are alopecia, neutropenia, sensory neuropathy, abnormal ECG, fatigue/asthenia, myalgia/arthralgia, AST elevation, alkaline phosphatase elevation, anemia, nausea, infections, and diarrhea [see Adverse Reactions (6.1)]. The most common adverse reactions (â&#x2030;Ľ 20%) of ABRAXANE in combination with carboplatin for non-small cell lung cancer are anemia, neutropenia, thrombocytopenia, alopecia, peripheral neuropathy, nausea, and fatigue [see Adverse Reactions (6.2)] The most common serious adverse reactions of ABRAXANE in combination with carboplatin for non-small cell lung cancer are anemia (4%) and pneumonia (3%). The most common adverse reactions resulting in permanent discontinuation of ABRAXANE were neutropenia (3%), thrombocytopenia (3%), and peripheral neuropathy (1%). The most common adverse reactions resulting in dose reduction of ABRAXANE were neutropenia (24%), thrombocytopenia (13%), and anemia (6%). The most common adverse reactions leading to withholding or delay in ABRAXANE dosing were neutropenia (41%), thrombocytopenia (30%), and anemia (16%). 6.1 Clinical Trials Experience in Metastatic Breast Cancer Table 3 shows the frequency of important adverse events in the randomized comparative trial for the patients who received either single-agent ABRAXANE or paclitaxel injection for the treatment of metastatic breast cancer.

Adverse Event Experiences by Body System Hematologic Disorders Neutropenia was dose dependent and reversible. Among patients with metastatic breast cancer in the randomized trial, neutrophil counts declined below 500 cells/mm3 (Grade 4) in 9% of the patients treated with a dose
of 260 mg/m2 compared to 22% in patients receiving paclitaxel injection at a dose of 175 mg/m2. Pancytopenia has been observed in clinical trials. Infections Infectious episodes were reported in 24% of the patients treated with ABRAXANE. Oral candidiasis, respiratory tract infections and pneumonia were the most frequently reported infectious complications. Hypersensitivity Reactions (HSRs) Grade 1 or 2 HSRs occurred on the day of ABRAXANE administration and consisted of dyspnea (1%) and flushing, hypotension, chest pain, and arrhythmia (all <1%). The use of ABRAXANE in patients previously exhibiting hypersensitivity to paclitaxel injection or human albumin has not been studied. Cardiovascular Hypotension, during the 30-minute infusion, occurred in 5% of patients. Bradycardia, during the 30-minute infusion, occurred in <1% of patients. These vital sign changes most often caused no symptoms and required neither specific therapy nor treatment discontinuation. Severe cardiovascular events possibly related to single-agent ABRAXANE occurred in approximately 3% of patients. These events included cardiac ischemia/infarction, chest pain, cardiac arrest, supraventricular tachycardia, edema, thrombosis, pulmonary thromboembolism, pulmonary emboli, and hypertension. Cases of cerebrovascular attacks (strokes) and transient ischemic attacks have been reported. Electrocardiogram (ECG) abnormalities were common among patients at baseline. ECG abnormalities on study did not usually result in symptoms, were not dose-limiting, and required no intervention. ECG abnormalities were noted in 60% of patients. Among patients with a normal ECG prior to study entry, 35% of all patients developed an abnormal tracing while on study. The most frequently reported ECG modifications were non-specific repolarization abnormalities, sinus bradycardia, and sinus tachycardia. Respiratory Dyspnea (12%), cough (7%), and pneumothorax (<1%) were reported after treatment with ABRAXANE. Neurologic The frequency and severity of sensory neuropathy increased with cumulative dose. Sensory neuropathy was the cause of ABRAXANE discontinuation in 7/229 (3%) patients. Twenty-four patients (10%) treated with ABRAXANE developed Grade 3 peripheral neuropathy; of these patients, 14 had documented improvement after a median of 22 days; 10 patients resumed treatment at a reduced dose of ABRAXANE and 2 discontinued due to peripheral neuropathy. Of the 10 patients without documented improvement, 4 discontinued the study due to peripheral neuropathy. No Grade 4 sensory neuropathies were reported. Only one incident of motor neuropathy (Grade 2) was observed in either arm of the controlled trial. Vision Disorders Ocular/visual disturbances occurred in 13% of all patients (n=366) treated with ABRAXANE and 1% were severe. The severe cases (keratitis and blurred vision) were reported in patients who received higher doses than those recommended (300 or 375 mg/m2). These effects generally have been reversible. Arthralgia/Myalgia The symptoms were usually transient, occurred two or three days after ABRAXANE administration, and resolved within a few days. Hepatic Grade 3 or 4 elevations in GGT were reported for 14% of patients treated with ABRAXANE and 10% of patients treated with paclitaxel injection in the randomized trial. Renal Overall 11% of patients experienced creatinine elevation, 1% severe. No discontinuations, dose reductions, or dose delays were caused by renal toxicities. Other Clinical Events Nail changes (changes in pigmentation or discoloration of nail bed) have been reported. Edema occurred in 10% of patients; no patients had severe edema. Dehydration and pyrexia were also reported. 6.2 Clinical Trials Experience in Non-Small Cell Lung Cancer Adverse reactions were assessed in 514 ABRAXANE/carboplatin-treated patients and 524 paclitaxel injection/carboplatin-treated patients receiving first-line systemic treatment for locally advanced (stage IIIB) or metastatic (IV) non-small cell lung cancer (NSCLC) in a multicenter, randomized, open-label trial. ABRAXANE was administered as an intravenous infusion over 30 minutes at a dose of 100 mg/m2 on Days 1, 8, and 15 of each 21-day cycle. Paclitaxel injection was administered as an intravenous infusion over 3 hours at a dose of 200 mg/m2, following premedication. In both treatment arms carboplatin at a dose of AUC = 6 mg•min/mL was administered intravenously on Day 1 of each 21-day cycle after completion of ABRAXANE/paclitaxel infusion. The differences in paclitaxel dose and schedule between the two arms limit direct comparison of dose- and schedule-dependent adverse reactions. Among patients evaluable for adverse reactions, the median age was 60 years, 75% were men, 81% were White, 49% had adenocarcinoma,
43% had squamous cell lung cancer, 76% were ECOG PS 1. Patients in both treatment arms received a median of 6 cycles of treatment. The following common (≥ 10% incidence) adverse reactions were observed at a similar incidence in ABRAXANE plus carboplatin-treated and paclitaxel injection plus carboplatin-treated patients: alopecia 56%, nausea 27%, fatigue 25%, decreased appetite 17%, asthenia 16%, constipation 16%, diarrhea 15%, vomiting 12%, dyspnea 12%, and rash 10% (incidence rates are for the ABRAXANE plus carboplatin treatment group). Table 4 provides the frequency and severity laboratory-detected abnormalities which occurred with a difference of ≥ 5% for all grades (1-4) or ≥ 2% for Grade 3-4 toxicity between ABRAXANE plus carboplatin-treated patients or paclitaxel injection plus carboplatin-treated patients.

neuropathy is defined by the MedDRA Version 14.0 SMQ neuropathy (broad scope). For the ABRAXANE plus carboplatin treated group, 17/514 (3%) patients developed Grade 3 peripheral neuropathy and no patients developed Grade 4 peripheral neuropathy. Grade 3 neuropathy improved to Grade 1 or resolved in 10/17 patients (59%) following interruption or discontinuation of ABRAXANE. 6.3 Post-Marketing Experience with ABRAXANE and other Paclitaxel Formulations Unless otherwise noted, the following discussion refers to the adverse reactions that have been identified during post-approval use of ABRAXANE. 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. In some instances, severe events observed with paclitaxel injection may be expected to occur with ABRAXANE. Hypersensitivity Reactions Severe and sometimes fatal hypersensitivity reactions have been reported with ABRAXANE. The use of ABRAXANE in patients previously exhibiting hypersensitivity to paclitaxel injection or human albumin has not been studied. Cardiovascular There have been reports of congestive heart failure and left ventricular dysfunction with ABRAXANE. Most of the individuals were previously exposed to cardiotoxic drugs, such as anthracyclines, or had underlying cardiac history.
Respiratory There have been reports of pneumonitis, interstitial pneumonia and pulmonary embolism in patients receiving ABRAXANE and reports of radiation pneumonitis in patients receiving concurrent radiotherapy. Reports of lung fibrosis have been received as part of the continuing surveillance of paclitaxel injection safety and may also be observed with ABRAXANE. Neurologic Cranial nerve palsies and vocal cord par esis have been reported, as well as autonomic neuropathy resulting in paralytic ileus. Vision Disorders Reports in the literature of abnormal visual evoked potentials in patients treated with paclitaxel injection suggest persistent optic nerve damage. These may also be observed with ABRAXANE. Reduced visual acuity due to cystoid macular edema (CME) has been reported during treatment with ABRAXANE as well as with other taxanes. After cessation of treatment, CME improves and visual acuity may return to baseline. Hepatic Reports of hepatic necrosis and hepatic encephalopathy leading to death have been received as part of the continuing surveillance of paclitaxel injection safety and may occur following ABRAXANE treatment. Gastrointestinal (GI) There have been reports of intestinal obstruction, intestinal perforation, pancreatitis, and ischemic colitis following ABRAXANE treatment. There have been reports of neutropenic enterocolitis (typhlitis), despite the coadministration of G-CSF, occurring in patients treated with paclitaxel injection alone and in combination with other chemotherapeutic agents. Injection Site Reaction There have been reports of extravasation of ABRAXANE. Given the possibility of extravasation, it is advisable to monitor closely the ABRAXANE infusion site for possible infiltration during drug administration. Severe events such as phlebitis, cellulitis, induration, necrosis, and fibrosis have been reported as part of the continuing surveillance of paclitaxel injection safety. In some cases the onset of the injection site reaction in paclitaxel injection patients either occurred during a prolonged infusion or was delayed by a week to ten days. Recurrence of skin reactions at a site of previous extravasation following administration of paclitaxel injection at a different site, i.e., “recall”, has been reported. Other Clinical Events Skin reactions including generalized or maculopapular rash, erythema, and pruritus have been observed with ABRAXANE. There have been case reports of photosensitivity reactions, radiation recall phenomenon, and in some patients previously exposed to capecitabine, reports of palmar-plantar erythrodysesthesia. Stevens-Johnson syndrome and toxic epidermal necrolysis have been reported. There have been reports of conjunctivitis, cellulitis, and increased lacrimation with paclitaxel injection. 6.4 Accidental Exposure No reports of accidental exposure to ABRAXANE have been received. However, upon inhalation of paclitaxel, dyspnea, chest pain, burning eyes, sore throat, and nausea have been reported. Following topical exposure, events have included tingling, burning, and redness. 7 DRUG INTERACTIONS The metabolism of paclitaxel is catalyzed by CYP2C8 and CYP3A4. In the absence of formal clinical drug interaction studies, caution should be exercised when administering ABRAXANE concomitantly with medicines known to inhibit (e.g., ketoconazole and other imidazole antifungals, erythromycin, fluoxetine, gemfibrozil, cimetidine, ritonavir, saquinavir, indinavir, and nelfinavir) or induce (e.g., rifampicin, carbamazepine, phenytoin, efavirenz, and nevirapine) either CYP2C8 or CYP3A4. There are no clinically important pharmacokinetic drug-drug interactions between carboplatin and ABRAXANE [see Clinical Pharmacology (12.3)]. 8 USE IN SPECIFIC POPULATIONS 8.1 Pregnancy Pregnancy Category D [see Warnings and Precautions (5.6)]. There are no adequate and well-controlled studies in pregnant women using ABRAXANE. Based on its mechanism of action and findings in animals, ABRAXANE can cause fetal harm when administered to a pregnant woman. 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. Women of childbearing potential should be advised to avoid becoming pregnant while receiving ABRAXANE. Administration of paclitaxel protein-bound particles to rats during pregnancy, on gestation days 7 to 17 at doses of 6 mg/m2 (approximately 2% of the daily maximum recommended human dose on a mg/m2 basis) caused embryofetal toxicities, as indicated by intrauterine mortality, increased resorptions (up to 5-fold), reduced numbers of litters and live fetuses, reduction in fetal body weight and increase in fetal anomalies. Fetal anomalies included soft tissue and skeletal malformations, such as eye bulge, folded retina, microphthalmia, and dilation of brain ventricles. A lower incidence of soft tissue and skeletal malformations were also exhibited at 3 mg/m2 (approximately 1% of the daily maximum recommended human dose on a mg/m2 basis).
8.3 Nursing Mothers It is not known whether paclitaxel is excreted in human milk. Paclitaxel and/or its metabolites were excreted into the milk of lactating rats. Because many drugs are excreted in human milk and because of the potential for serious adverse reactions in nursing infants, a decision should be made 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 ABRAXANE in pediatric patients have not been evaluated. 8.5 Geriatric Use Of the 229 patients in the randomized study who received ABRAXANE for the treatment of metastatic breast cancer, 13% were at least 65 years of age and < 2% were 75 years or older. No toxicities occurred notably more frequently among patients who received ABRAXANE. Of the 514 patients in the randomized study who received ABRAXANE and carboplatin for the first-line treatment of non-small cell lung cancer, 31% were 65 years or older and 3.5% were 75 years or older. Myelosuppression, peripheral neuropathy, and arthralgia were more frequent in patients 65 years or older compared to patients younger than 65 years old. No overall difference in effectiveness, as measured by response rates, was observed between patients 65 years or older compared to patients younger than 65 years old. 8.6 Patients with Hepatic Impairment Because the exposure and toxicity of paclitaxel can be increased in patients with hepatic impairment, the administration of ABRAXANE should be performed with caution in patients with hepatic impairment [see Dosage and Administration (2.3), Warnings and Precautions (5.4) and Clinical Pharmacology (12.3)]. 8.7 Patients with Renal Impairment The use of ABRAXANE has not been studied in patients with renal impairment. 10 OVERDOSAGE There is no known antidote for ABRAXANE overdosage. The primary anticipated complications of overdosage would consist of bone marrow suppression, sensory neurotoxicity, and mucositis. 16 HOW SUPPLIED/STORAGE AND HANDLING 16.1 How Supplied Product No.: 103450 NDC No.: 68817-134-50 100 mg of paclitaxel in a single-use vial, individually packaged in a carton. 16.2 Storage Store the vials in original cartons at 20°C to 25°C (68° F to 77°F). Retain in the original package to protect from bright light. 16.3 Handling and Disposal Procedures for proper handling and disposal of anticancer drugs should be considered. Several guidelines on this subject have been published [see References (15)]. There is no general agreement that all of the procedures recommended in the guidelines are necessary or appropriate. 17 PATIENT COUNSELING INFORMATION See FDA-Approved Patient Labeling (Patient Information). • ABRAXANE injection may cause fetal harm. Advise patients to avoid becoming pregnant while receiving this drug. Women of childbearing potential should use effective contraceptives [see Warnings and Precautions (5.6) and Use in Specific Populations (8.1)]. • Advise men not to father a child while receiving ABRAXANE [see Warnings and Precautions (5.7)]. • Patients must be informed of the risk of low blood cell counts and instructed to contact their physician immediately for fever or evidence of infection. • Patients should be instructed to contact their physician for persistent vomiting, diarrhea, signs of dehydration, cough or breathing difficulties, or signs of an allergic reaction. • Patients must be informed that sensory neuropathy occurs frequently with ABRAXANE and patients should advise their physicians of numbness, tingling, pain or weakness involving the extremities [see Warnings and Precautions (5.2)]. • Explain to patients that alopecia, fatigue/asthenia, and myalgia/arthralgia occur frequently with ABRAXANE. • Patients must be informed that hypersensitivity reactions may occur, which could be severe and sometimes fatal.

Omacetaxine for Chronic or Accelerated Phase CML Patients with Resistance/Intolerance to Tyrosine Kinase Inhibitors 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 October 26, 2012, the FDA granted accelerated approval to omacetaxine mepesuccinate (Synribo) for the treatment of adult patients with chronic phase or accelerated phase chronic myeloid leukemia (CML) with resistance or intolerance to two or more tyrosine kinase inhibitors.1,2 The decision was based on response rates. As yet, there are no trials verifying an improvement in disease-related symptoms or increased survival with omacetaxine.
OF NOTE Omacetaxine’s approval was based on response rates; no trials have yet demonstrated an improvement in disease-related symptoms or increased survival. Approval was based on findings in a combined cohort of adult patients with CML from two trials.1–3 All patients had received two or more approved tyrosine kinse inhibitors and had evidence of resistance or intolerance to dasatinib (Sprycel) or nilotinib (Tasigna). Patients with New York Heart Association class III or IV heart disease, active ischemia, or other uncontrolled cardiac conditions were excluded from the studies. Patients received subcutaneous omacetaxine at 1.25 mg/m2 twice daily for 14 consecutive days every 28
days (induction cycle). Responding patients received the same dose for 7 consecutive days every 28 days (maintenance cycle). Patients could receive maintenance treatment for up to 24 months. Among 76 patients with chronic phase CML, median age was 59 years, 62% were male, 30% were aged ≥ 65 years, and 80% were Caucasian; in 47%, treatment with imatinib (Gleevec), dasatinib, and nilotinib had failed, and most had received prior non–tyrosine kinase inhibitor treatments, most commonly hydroxyurea (54%), interferon (30%), and cytarabine (29%). A major cytogenetic response occurred in 14 patients (18.4%, 95%��������������� �������������� confidence interval [CI] = 10.5%–29.0%). Among patients with major cytogenetic response, mean time to onset was 3.5 months and median response duration was 12.5 months. Among 35 patients with accelerated phase CML, median age was 63 years, 57% were male, 46% were aged ≥ 65 years, and 68% were Caucasian (23% African American); 63% had failed treatment with imatinib, dasatinib, and nilotinib and most had received prior non–tyrosine kinase inhibitor treatments, most commonly hydroxyurea (43%), interferon (31%), and cytarabine (29%). Major hematologic response occurred in 5 patients (14.3%, 95% CI = 4.5%–30.3%); none of the patients had a major cytogenetic response. Among patients with major hematologic response, mean time to onset was 2.3 months and median duration of response was 4.7 months.
How It Works The mechanism of action of omacetaxine mepesuccinate has not been fully elucidated, but it includes inhibition of protein synthesis and activity that is independent of direct Bcr-Abl
Omacetaxine in Chronic Myeloid Leukemia ■■ Omacetaxine mepesuccinate (Synribo) was approved to treat adults with chronic or accelerated phase chronic myeloid leukemia who are resistant or intolerant to two or more tyrosine kinase inhibitors.
■■ The induction dose is 1.25 mg/m2 via subcutaneous injection twice daily
for 14 consecutive days of a 28-day cycle, repeated every 28 days until hematologic response; the maintenance dose is 1.25 mg/m2 twice daily for 7 consecutive days of a 28-day cycle.
binding. It binds to the A-site cleft in the peptidyl-transferase center of the large ribosomal subunit from a strain of archaeabacteria. The agent was found to have activity in CML patients in the pre–tyrosine kinase inhibitor era. In vitro, omacetaxine reduces levels of the Bcr-Abl oncoprotein and Mcl-1, an antiapoptotic Bcl-2 family member, and its activity is not affected by presence of Bcr-Abl mutations. It has exhibited activity in mouse models of wild-type and T315I mutant Bcr-Abl CML and in CML patients with the T315I mutation.
Study Endpoints Major cytogenetic response: 0%–35% Philadelphia chromosome–positive metaphases in the bone marrow with at least 20 metaphases Major hematologic response: Either a complete hematologic response (normal peripheral complete blood count and differential and the absence of blasts in the blood) or no evidence of leukemia in the setting of peripheral blood counts that have not normalized
How It Is Given Omacetaxine is given at an induction dose of 1.25 mg/m2 via subcutaneous injection twice daily for 14 consecutive days of a 28-day cycle; cycles should be repeated every 28 days until patients achieve a hematologic response. The recommended maintenance dose is 1.25 mg/m2 via subcutaneous injection twice daily for 7 consecutive days of a 28-day cycle. Treatment should continue for as long as clinical benefit is observed. Treatment cycles may be delayed or the number of days of dosing during the cycle reduced for hematologic toxicities (eg, neutropenia, thrombocytopenia). Complete blood counts should be performed weekly during induction and initial maintenance cycles. After initial maintenance cycles, complete blood counts should be monitored every 2 weeks or as clinically indicated. In patients experiencing grade 4 neutropenia or grade 3 thrombocytopenia, the next cycle should be delayed until

Safety Profile Safety data are from 163 patients receiving omacetaxine in clinical trials. Among 108 patients with chronic phase CML, 87% had grade 3 or 4 adverse events, including thrombocytopenia (67%), neutropenia (45%), anemia (36%), bone marrow failure (16%), and febrile neutropenia (10%); the most common grade 3 or 4 nonheSee Page 101 matologic adverse events were infections/infestations (11%; bacterial, fungal, viral, nonspecified) and fatigue (5%). Serious adverse events occurred in 51% of patients with chronic phase CML, with the most common being bone marrow failure (10%), thrombocytopenia (10%), infection (8%), and febrile neutropenia (6%). Discontinuation due to adverse events occurred in 18% of patients, with the most common reasons being pancytopenia, thrombocytopenia, and increased ALT (2% each). Death occurred in five patients (5%), due to cerebral hemorrhage in two, multiorgan failure in one, disease progression in one, and unknown cause in one. Among 55 patients with accelerated phase CML, 84% had grade 3 or 4 adverse events, including thrombocycontinued on page 36

Faster Rituximab Infusion for Previously Untreated Follicular Non-Hodgkin and Diffuse Large B-cell Lymphomas By Matthew Stenger
O
n October 19, 2012, FDA approved a 90-minute infusion for rituximab (Rituxan) starting at cycle 2 for patients with previously untreated follicular non-Hodgkin or diffuse large B-cell lymphoma who do not experience a grade 3 or 4 infusion-related reaction during cycle 1.1 Patients with clinically significant cardiovascular disease and those with high circulating lymphocyte counts (≥ 5,000/µL) before cycle 2 should not receive the faster infusion. The non-Hodgkin lymphoma indications affected by the approval are previously untreated follicular, CD20-positive, B-cell non-Hodgkin lymphoma in combination with first-line chemotherapy and previously untreated diffuse large B-cell lymphoma in combination with CHOP (cyclophosphamide, doxorubicin, vincristine, and prednisone) or other anthracycline-based chemotherapy regimens. The recommended dose of rituximab in non-Hodgkin lymphoma is 375 mg/ m2 via IV infusion given on day 1 of each cycle of chemotherapy for up to eight doses in both follicular non-Hodgkin and diffuse large B-cell lymphoma patients. For the initial dose in cycle 1, rituximab infusion is initiated at a rate of 50 mg/h; in the absence of infusion toxicity, the rate is increased by 50 mg/h increments every 30 minutes to a maximum of 400 mg/h.

New Infusion Recommendations Under the new approval, a 90-minute infusion can be administered in cycle 2 with a glucocorticoid-containing regimen in patients who do not experience a grade������������������������������������ ����������������������������������� 3 or 4 infusion-related adverse reaction in cycle 1. The 90-minute infusion is started at a rate of 20% of the total dose given in the first 30 minutes, with the remaining 80% of the total dose given over the next 60 minutes. If the 90-minute infusion is tolerated in cycle 2, the same rate can be used when administering the remainder of the treatment regimen (through cycle 6 or 8).
First-line Rapid-infusion Rituximab in Lymphoma ■■ FDA has approved a 90-minute infusion for rituximab (Rituxan) starting
at cycle 2 for patients with previously untreated follicular non-Hodgkin or diffuse large B-cell lymphoma who do not experience a grade 3/4 infusionrelated reaction during cycle 1.

phoma patients (who received CHOP). No grade 4 or 5 infusion-related reactions were reported in cycle 2. These results are comparable to those reported for cycle 2 in rituximab trials using the standard infusion regimen.
Approval of the faster infusion rate is based on findings in an open-label, single-arm, multicenter phase III trial (RATE trial) in which 363 patients with previously untreated follicular non-Hodgkin lymphoma (n = 113) or diffuse large B-cell lymphoma (n = 250) received rituximab 375 mg/ m2 plus CVP (cyclophosphamide, vincristine, prednisone) in follicular non-Hodgkin lymphoma patients and CHOP in diffuse large B-cell lymphoma patients.2 Patients with clinically significant cardiovascular disease were excluded from the study. Patients were eligible for a 90-minute rituximab infusion in cycle 2 if

are no identified drug interactions with omacetaxine and no recommendations for dose modifications according to renal or hepatic function or with concomitant administration of CYP450 inducers or inhibitors (omacetaxine is not a substrate of CYP450 enzymes). There are no specific contraindications to omacetaxine use. n
OF NOTE The faster infusion is contraindicated in cases of clinically significant cardiovascular disease and high circulating lymphocyte counts before cycle 2.
RATE Trial Details
The main outcome measure of the trial was the development of grade 3 or 4 infusion-related reactions on the day of or the day after the 90-minute infusion in cycle 2. The incidence of grade 3 infusion-related reactions in cycle 2 was 1.1% (95% confidence interval [CI] = 0.3%–2.8%) among See Page 101 all patients, including an incidence of 3.5% (95% CI = 1.0%–8.8%) in follicular non-Hodgkin lymphoma patients (who received CVP) and 0.0% (95% CI = 0.0%–1.5%) in diffuse large B-cell lym-

Important Safety Information Contraindications XTANDI can cause fetal harm when administered to a pregnant woman based on its mechanism of action. XTANDI is not indicated for use in women. XTANDI is contraindicated in women who are or may become pregnant. Warnings and Precautions In the randomized clinical trial, seizure occurred in 0.9% of patients on XTANDI. No patients on the placebo arm experienced seizure. Patients experiencing a seizure were permanently discontinued from therapy. All seizures resolved. Patients with a history of seizure, taking medications known to decrease the seizure threshold, or with other risk factors for seizure were excluded from the clinical trial. Because of the risk of seizure associated with XTANDI use, patients should be advised of the risk of engaging in any activity where sudden loss of consciousness could cause serious harm to themselves or others. Adverse Reactions The most common adverse drug reactions (≥ 5%) reported in patients receiving XTANDI in the randomized clinical trial
with XTANDI 160 mg once daily experienced a seizure. No seizures occurred in patients treated with placebo1
were asthenia/fatigue, back pain, diarrhea, arthralgia, hot flush, peripheral edema, musculoskeletal pain, headache, upper respiratory infection, muscular weakness, dizziness, insomnia, lower respiratory infection, spinal cord compression and cauda equina syndrome, hematuria, paresthesia, anxiety, and hypertension. Drug Interactions XTANDI is a strong CYP3A4 inducer and a moderate CYP2C9 and CYP2C19 inducer in humans. Administration of strong CYP2C8 inhibitors can increase the plasma exposure to XTANDI. Co-administration of XTANDI with strong CYP2C8 inhibitors should be avoided if possible. If co-administration of XTANDI cannot be avoided, reduce the dose of XTANDI. Co-administration of XTANDI with strong or moderate CYP3A4 and CYP2C8 inducers can alter the plasma exposure of XTANDI and should be avoided if possible. Avoid CYP3A4, CYP2C9 and CYP2C19 substrates with a narrow therapeutic index, as XTANDI may decrease the plasma exposures of these drugs. If XTANDI is co-administered with warfarin (CYP2C9 substrate), conduct additional INR monitoring. Please see adjacent pages for Brief Summary of Full Prescribing Information.

XTANDI is not indicated for use in women. XTANDI is contraindicated in women who are or may become pregnant. If this drug is used during pregnancy, or if the patient becomes pregnant while taking this drug, apprise the patient of the potential hazard to the fetus and the potential risk for pregnancy loss >VHH 8VH LQ 6SHFLÂżF 3RSXODWLRQV@. -------------------------- WARNINGS AND PRECAUTIONS ------------------------Seizure In the randomized clinical trial, 7 of 800 (0.9%) patients treated with XTANDI 160 mg once daily experienced a seizure. No seizures occurred in patients treated with placebo. Seizures occurred from 31 to 603 days after initiation of XTANDI. Patients experiencing seizure were permanently discontinued from therapy and all seizures resolved. There is no clinical trial experience re-administering XTANDI to patients who experienced seizures. The safety of XTANDI in patients with predisposing factors for seizure is not known because these patients were excluded from the trial. These exclusion criteria included a history of seizure, underlying brain injury with loss of consciousness, transient ischemic attack within the past 12 months, cerebral vascular accident, brain metastases, brain arteriovenous malformation or the use of concomitant medications that may lower the seizure threshold. Because of the risk of seizure associated with XTANDI use, patients should be advised of the risk of engaging in any activity where sudden loss of consciousness could cause serious harm to themselves or others. --------------------------------- ADVERSE REACTIONS ------------------------------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 WR UDWHV LQ WKH FOLQLFDO WULDOV RI DQRWKHU GUXJ DQG PD\ QRW UHĂ&#x20AC;HFW WKH UDWHV REVHUYHG in practice.

While there are no human or animal data on the use of XTANDI in pregnancy and XTANDI is not indicated for use in women, it is important to know that maternal use of an androgen receptor inhibitor could affect development of the fetus. XTANDI is contraindicated in women who are or may become pregnant while receiving the drug. If this drug is used during pregnancy, or if the patient becomes pregnant while taking this drug, apprise the patient of the potential hazard to the fetus and the potential risk for pregnancy loss. Advise females of reproductive potential to avoid becoming pregnant during treatment with XTANDI. Nursing Mothers XTANDI is not indicated for use in women. It is not known if enzalutamide 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 XTANDI, a decision should be made to either discontinue nursing, or discontinue the drug taking into account the importance of the drug to the mother.

Management of Brain Metastases By Ganesh Shankar, MD, PhD, and Daniel P. Cahill, MD, PhD
A
n increasing portion of patients with cancer are manifesting brain metastases, with a prevalence of up to 40% and an incidence of approximately 170,000 new cases per year in the United States. The goal for management of brain metastasis is to achieve control of symptoms and recurrence, both at existing sites of metastasis (local control) and through the prevention of new lesions (distal or regional control). This control can then contribute, in combination with systemic treatments, to improved neurologic function, performance staDr. Shankar is Senior Resident, Department of Neurosurgery, Massachusetts General Hospital.

tus, and potentially overall survival. The evidence-based treatment of brain metastasis in any individual patient will often incorporate surgical resection, stereotactic radiosurgery, and whole-brain radiation therapy over the course of the illness.1 Most importantly, treatments directed at brain metastases must be coordinated with treatments for systemic disease. Here, we frame the key considerations for appropriately guiding therapeutic decisions for patients with brain metastases.
Patient Characteristics Decision-making about brain metastases requires knowledge of expected overall survival in a patient with metastatic cancer. Will this patient live long enough that control of metastatic disease in the brain will
contribute to an improvement in overall outcome? In historical studies, improved survival in patients with brain metastases was associated with age ≤ 65 years, Karnofsky performance status (KPS) ≥ 70, controlled systemic disease, and isolated brain relapse. A recently proGanesh Shankar, MD, PhD Daniel P. Cahill, MD, PhD posed Diagnosis-Specific metastases.

Clinical equipoise remains on the management of asymptomatic lesions between 1 cm and 3 cm, for which local control can be achieved by either surgery or stereotactic radiosurgery.

Two randomized controlled trials demonstrate survival benefit with surgical resection and whole-brain radiotherapy as compared with whole-brain radiotherapy alone for the management of a single brain metastasis in patients with good performance status. Level 2 evidence suggests that lesions larger than 3���������������������������������� ��������������������������������� cm or those resulting in mass effect may have improved outcomes with surgical resection rather than stereotactic radiosurgery. Taken together with the randomized controlled trial data for stereotactic radiosurgery of a single lesion (see below), there is strong evidence for a survival benefit from an initial strategy of focally directed therapy (surgery or stereotactic radiosurgery) for patients with a single brain metastasis and good performance status. Available data are insufficient to guide management for patients with lower performance status (KPS < 70). This subgroup may have decreased overall survival secondary to systemic continued on page 48

Important Safety Information. AFINITOR® (everolimus) Tablets is contraindicated in patients with hypersensitivity to everolimus, to other rapamycin derivatives, or to any of the excipients. Noninfectious Pneumonitis: • Noninfectious pneumonitis was reported in up to 19% of patients treated with AFINITOR. The incidence of Common Terminology Criteria (CTC) grade 3 and 4 noninfectious pneumonitis was up to 4.0% and up to 0.2%, respectively. Fatal outcomes have been observed • If symptoms are moderate, patients should be managed with dose interruption until symptoms improve • The use of corticosteroids may be indicated. For grade 4 cases, discontinue AFINITOR. Corticosteroids may be indicated until symptoms resolve • For grade 3 cases, interrupt AFINITOR until resolution to grade ≤1 • AFINITOR may be reintroduced at a daily dose approximately 50% lower than the dose previously administered, depending on the individual clinical circumstances. 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 those with opportunistic pathogens). 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 • Some of these infections have been severe (eg, leading to respiratory or hepatic failure) or fatal • Physicians and patients should be aware of the increased risk of infection with AFINITOR • Treatment of preexisting invasive fungal infections should be completed prior to starting treatment • Be vigilant for signs and symptoms of infection and institute appropriate treatment promptly; interruption or discontinuation of AFINITOR should be considered • Discontinue AFINITOR if invasive systemic fungal infection is diagnosed and institute appropriate antifungal treatment Oral Ulceration: • Mouth ulcers, stomatitis, and oral mucositis have occurred in patients treated with AFINITOR at an incidence ranging from 44% to 86% across the clinical trial experience. Grade 3/4 stomatitis was reported in 4% to 9% of patients • In such cases, topical treatments are recommended, but alcohol-, peroxide-, iodine-, or thyme-containing mouthwashes should be avoided • Antifungal agents should not be used unless fungal infection has been diagnosed Renal Failure: • Cases of renal failure (including acute renal failure), some with a fatal outcome, have been observed in patients treated with AFINITOR 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 discontinuation occurred in 33% of patients ≥65 years of age compared with 17% in patients <65 years of age

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.

No study has yet been reported with enough power to observe a difference in survival for patients receiving stereotactic radiosurgery alone compared to those undergoing stereotactic radiosurgery and whole-brain radiotherapy. However, there has been a significant difference
progression, and thus local control of asymptomatic brain lesions may not improve their overall outcome.
Stereotactic Radiosurgery While resection is recommended for single brain metastases larger than 3 cm in locations amenable to surgery, stereotactic radiosurgery appears to offer an equivalent option for the management of a smaller single lesion in terms of local control and survival (Fig. 2).3 Level 1 evidence supports the use of stereotactic radiosurgery for single brain metastases (in addition to whole-brain radiotherapy) in patients with KPS ≥ 70 to obtain improved survival. Indeed, with regard to lesions <���������������������������� ��������������������������� 3�������������������������� ������������������������� cm, level���������������� ��������������� 2 evidence suggests equivalence of surgical resection and stereotactic radiosurgery when used together with whole-brain radiotherapy in terms of recurrence and survival rates. Stereotactic radiosurgery combined with whole-brain radiotherapy may be superior to whole-brain irradiation alone to preserve function in patients with two to four metastatic lesions. Which patients with multiple metastases may benefit from stereotactic radiosurgery is currently an area of active study; factors such as tumor histology or potential response to systemic targeted therapeutics may play an important role.
reserved as salvage therapy at the time of brain recurrence. Ongoing randomized controlled trials will clarify whether withholding of upfront whole-brain radiotherapy affects intracranial recurrence, survival, and neurocognitive function, with the hope that evidence-based criteria can be developed to guide the sequenced application of these treatments.
The goal of brain metastasis management is to achieve local and regional control as a means of preserving performance status and neurologic function and potentially improving overall survival. —Ganesh Shankar, MD, PhD, and Daniel R. Cahill, MD, PhD
noted in local and distant recurrence in patients for whom whole-brain radiotherapy is withheld. The timing of wholebrain irradiation has therefore been controversial. Patients with asymptomatic brain metastases and extensive systemic disease are able to initiate chemotherapy sooner if the intracranial disease is initially treated with stereotactic radiosurgery, and whole-brain radiotherapy is withheld until distal failure in the brain. Given the lack of clear survival benefit and the well known detrimental effects on cognitive function with adjuvant wholebrain radiation therapy,4 an alternative treatment paradigm is close postoperative (or post–stereotactic radiosurgery) surveillance, with whole-brain radiotherapy
Recommendations The goal of brain metastasis management is to achieve local and regional control as a means of preserving performance status and neurologic function and potentially improving overall survival. Patients with a single brain metastasis (up to 30% of patients on initial presentation) have a proven survival benefit from focally directed therapy (stereotactic radiosurgery or surgery). Surgical resection and stereotactic radiosurgery appear to have therapeutic equivalence for asymptomatic supratentorial lesions less than 3 cm. These modalities are particularly important for the local control of traditionally radioresistant histologies such

While whole-brain radiotherapy clearly affects intracranial recurrence rates when applied after resection or stereotactic radiosurgery, the effect on overall survival has been less easily demonstrable. Taken together with the potential detrimental effects of whole-brain radiotherapy on neurocognitive function, this has led to clinical trials to identify patient subgroups in which whole-brain irradiation may be reserved as salvage therapy. n Disclosure: Drs. Shankar and Cahill reported no potential conflicts of interest.
Fig. 2: (a–d) Screening MRI scan of a 46-year-old man with a past medical history of non–small cell lung cancer, demonstrating two lesions in the brain— one in the left frontoparietal region measuring 1.5 × 2.2 cm × 2 cm and one in the right parietal lobe measuring 1.6 × 1.7 cm × 1.8 cm (2a). Stereotactic radiosurgery was administered and followed by whole-brain radiation therapy. These enhancing lesions were less noticeable at 1 month (2b) and 5 months (2c) post–stereotactic radiosurgery. Nine months later, the previously treated metastatic sites in the parietal areas seem to be stable (2d). No new lesions are appreciated. He ultimately died from progressive systemic disease 16 months after the cerebral metastases were treated. (2e–2h) A 59-year-old, right-handed woman with renal cell carcinoma presented with hemorrhagic metastasis in the left motor cortex 17 months following initial diagnosis. This lesion was in the motor cortex adjacent to the intrinsic hand motor area (2e). She underwent stereotactic radiosurgery with a decrease in enhancement at 2 months and 8 months post-treatment. She had neither recurrence nor new metastatic brain lesions on surveillance imaging for at least 15 months following stereotactic radiosurgery (2h).

In animal reproduction studies, when pregnant rabbits received pegfilgrastim at cumulative doses approximately 4 times the recommended human dose (based on body surface area), increased embryolethality and spontaneous abortions occurred. Signs of maternal toxicity (reductions in body weight gain/food consumption) and decreased fetal weights occurred at maternal doses approximately equivalent to the recommended human dose (based on body surface area). There were no structural anomalies observed in rabbit offspring at any dose tested. No evidence of reproductive/developmental toxicity occurred in the offspring of pregnant rats that received cumulative doses of pegfilgrastim approximately 10 times the recommended human dose (based on body surface area). Women who become pregnant during Neulasta treatment are encouraged to enroll in Amgen’s Pregnancy Surveillance Program. Patients or their physicians should call 1-800-77-AMGEN (1-800-772-6436) to enroll. Nursing Mothers It is not known whether pegfilgrastim is secreted in human milk. Other recombinant G-CSF products are poorly secreted in breast milk and G-CSF is not orally absorbed by neonates. Caution should be exercised when administered to a nursing woman. Pediatric Use Safety and effectiveness of Neulasta in pediatric patients have not been established. The adverse reaction profile and pharmacokinetics of pegfilgrastim were studied in 37 pediatric patients with sarcoma. The mean (± standard deviation [SD]) systemic exposure (AUC0-inf) of pegfilgrastim after subcutaneous administration at 100 mcg/kg was 22.0 (± 13.1) mcg·hr/mL in the 6 to 11 years age group (n = 10), 29.3 (± 23.2) mcg·hr/mL in the 12 to 21 years age group (n = 13), and 47.9 (± 22.5) mcg·hr/mL in the youngest age group (0 to 5 years, n = 11). The terminal elimination half-lives of the corresponding age groups were 20.2 (± 11.3) hours, 21.2 (± 16.0) hours, and 30.1 (± 38.2) hours, respectively. The most common adverse reaction was bone pain. Geriatric Use Of the 932 patients with cancer who received Neulasta in clinical studies, 139 (15%) were age 65 and over, and 18 (2%) were age 75 and over. No overall differences in safety or effectiveness were observed between patients age 65 and older and younger patients. Renal Impairment In a study of 30 subjects with varying degrees of renal dysfunction, including end stage renal disease, renal dysfunction had no effect on the pharmacokinetics of pegfilgrastim.Therefore, pegfilgrastim dose adjustment in patients with renal dysfunction is not necessary. DOSAGE AND ADMINISTRATION The recommended dosage of Neulasta is a single subcutaneous injection of 6 mg administered once per chemotherapy cycle in adults. Do not administer Neulasta between 14 days before and 24 hours after administration of cytotoxic chemotherapy. Visually inspect parenteral drug products for particulate matter and discoloration prior to administration, whenever solution and container permit. Do not administer Neulasta if discoloration or particulates are observed.

Health-care Policy
Accountable Care Organizations: The New Normal? By Richard J. Boxer, MD, FACS
Richard J. Boxer, MD, FACS
T
he accountable care organization was introduced into our lexicon during a public meeting of the Medicare Payment Advisory Commission in 2006, and the term became ubiquitous when it was specified in the Patient Protection and Affordable Care Act of 2010. After the November 6 election, accountable care organizations became a fact of life. The principle that defines the reason for accountable care organizations is the near-uniform belief that health care in America is fractionated, too expensive, and demands creative reform.
Basic Principles Through accountable care organizations, the Affordable Care Act envisions the transformation of current volume-based, potentially perverse incentives to overtest and overtreat, to value-based incentives for delivery of high-quality, lower-cost health care. These organizations are designed to coordinate care through a robust system of patient-centered primary care health professionals. However, medical and surgical specialists rapidly have Dr. Boxer is Clinical Professor at the University of Wisconsin, Madison, and the Medical College of Wisconsin (Milwaukee), and former Professor of Clinical Urology at the University of Miami.
become an integral part of these organizations. Oncology, which accounts for 10% of health-care expenses, certainly will be impacted. Although the Affordable Care Act described accountable care organizations as a means of coordinating care for Medicare beneficiaries, private insurers are embracing the concept. So, what exactly are accountable care organizations? Ideally, they are integrated systems of physicians and other health providers that increase
ing quality metrics. However, the projected budget for Medicare in that same period of time is $6.2 trillion. Thus, the extraordinary effort to create accountable care organizations will save approximately 0.08% of the Medicare budget. This is known by the Congressional Budget Office as “budget dust.” In addition, the estimate of legal and consulting fees to create the existing and near-future accountable care organizations is $1 billion. Already, 20% of the savings is consumed, and the process has just begun.
It is up to oncologists to honestly and transparently work for the benefit of the patient with cancer, but simultaneously understand that the status quo is over, and quality-based care that promotes improved outcomes will be the new normal. —Richard J. Boxer, MD, FACS
practices at a rapid pace. In 2000, 20% of primary care doctors and 5% of specialists were employed by hospital systems. In 2012, 40% of primary doctors and 22% of specialists are employed. And this will continue until the vast majority will be controlled. It is highly unlikely that this extraordinary aggregation of physicians and the creation of accountable care organizations is a coincidence. Physicians have always been an uncontrollable and independent lot. That, like fragmentation of care and fee-for-service, will soon be a historical vignette. Oncologists have a lot at stake. Throughout the nation, many practices are being purchased by integrated health systems. This may result in more oncologists integrating their practices into large single-specialty groups to preserve their independence and create outcomes and value-based oncology centers of excellence.
Accountability Question coordinated care and improve patient outcomes. They can be independent physician organizations, integrated delivery systems (hospitals and their participating physicians), multispecialty group practices, physician-hospital organizations (nonemployee medical staff), or virtual physician organizations (commonly in rural areas). Theoretically, the money saved by a successful accountable care organization will be shared in certain undetermined percentages by the insurer (including Medicare) and the organization itself (including the doctors). The Congressional Budget Office has predicted that accountable care organizations will save Medicare $5����� ���� billion over the first 8 years, by eliminating unnecessary or redundant procedures, sharing clinical information, and meet-
In further evidence of the money involved, it is estimated to cost $10 million to $30 million to create a fully functional accountable care organization. Who has that kind of money? The answer is commonly, but not uniquely, integrated health systems— ie, the hospitals.
Added Rationale H.L. Mencken famously said, “When somebody says it’s not about the money, it’s about the money.” Nevertheless, it seems clear that in the immediate future, there is little money to be saved or shared. Thus, the best reason to create and support the accountable care organization concept is for improved patient outcomes. But is there another reason? Hospital systems have been buying
The question on all physicians’ minds is: To whom are the accountable care organizations accountable? Physicians staunchly fight for the accountability to be to the patient, not the bottom line. Yet, one of the reasons for the Affordable Care Act is the crisis produced by the very system that physicians were central in creating. There is no turning back. The federal health-care legislation may be slightly modified, but it is the future of health-care delivery. It is up to oncologists to honestly and transparently work for the benefit of the patient with cancer, but simultaneously understand that the status quo is over, and qualitybased care that promotes improved outcomes will be the new normal. n

• Gliomas account for approxiately 80% of all malignant brain and central nervous system tumors in adults.1 Glioblastoma is the most aggressive form of gliomas.2 • Integrins are a family of at least 24 distinct cell surface heterodimer receptors. As cell surface receptors, integrins regulate cellular behavior by way of signal transmission between extracellular and intracellular spaces through interactions with extracellular ligands.3, 4, 5 • Integrins are overexpressed on tumor cells and vasculature but not widely expressed on normal tissues and blood vessels.3, 5 • The overexpression and activity of integrins are important for proliferation, migration, invasion, and survival of glioblastoma cells.3 Integrins also support tumor growth and progression by promoting tumor-associated angiogenesis.6 References 1.

JCO Spotlight Molecular Tumor Profiling
Gene Profiling Directs Site-specific Therapy for Carcinoma of Unknown Primary Site By Matthew Stenger
P
atients with carcinoma of unknown primary site usually receive empiric therapy (eg, with taxane/platinum or gemcitabine/ platinum regimens), resulting in a median overall survival of approximately 9������������������������ ����������������������� months. As reported recently in Journal of Clinical Oncology, Hainsworth and colleagues have shown that molecular tumor profiling with a 92-gene assay can predict tissue of origin in most patients, and that assay-directed site-specific treatment is associated with overall survival that compares favorably with that seen with empiric therapy.1
Study Details The study prospectively enrolled 289 patients with carcinoma of unknown primary. Patients had to have Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 2, no prior systemic chemotherapy, measurable or evaluable disease, and adequate organ function. Patients were excluded if they had a single resectable metastasis. Of the 289 patients, 252 (87%) had successful molecular profiling assays, with tumor samples or quantities of viable RNA in samples being inadequate for the remainder. Among the 252 patients with successful assays, median age was 64 years (range, 26–89 years), 54% were female, and 69% See Page 101 had two or more metastatic sites. Histology consisted of adenocarcinoma in 51%, poorly differentiated adenocarcinoma in 24%, poorly differentiated carcinoma in 18%, squamous carcinoma in 5%, poorly differentiated neuroendocrine carcinoma in 1%, and poorly differentiated neoplasm in 1%.
Four Tissues Account for 55% of Predicted Sites The assay predicted a tissue of origin in 247 (98%) of the 252 patients. Twenty-six different tissues of origin were identified. These included the biliary tract in 21%, urothelium in 12%, and colorectum and non-small cell lung in 11% each, with these sites accounting for 55% of all predicted
sites. Other predicted tissues of origin included: pancreas and breast in 5% each; ovary, gastroesophageal, and kidney in 4% each; and liver in 3%. Of the assay predictions, 119 (48%) were made with 80% or greater probability. Of the 252 patients with successful assays, 223 (88%) remained on study and received treatment. Of the 29 patients not remaining on study, 16 no longer met eligibility criteria (declining performance status in 15, brain metastases in 1) and 13 discontinued the study as a result of patient decision (refusal of recommended treatment) or physician preference (usually doubt regarding assay findings). Of these 223 patients, 194 (87%) received assay-directed therapy; of the 29 patients not receiving assay-directed therapy, 23 received treatment pre-
Gene Profiling to Determine Tissue of Cancer Origin ■■ The molecular profiling assay predicted a tissue of origin in 98% of patients with sufficient biopsy samples, with the prediction having at least 80% probability in 48% of these cases.
■■ The biliary tract, urothelium, colorectum, and non–small cell lung accounted for 55% of predicted tissues of origin.

overall survival was 13.4 months in 115 patients with tumor types considered to be treatment-responsive (ie, colorectal, breast, ovary, kidney, prostate, bladder, non–small cell lung, germ cell, poorly differentiated neuroendocrine, and small cell lung cancers) and 7.6 months (P = .04) in 79 patients with less-responsive tumor types (ie, biliary tract, pancreas,

Site-specific therapies consisted of the following: taxane/bevacizumab (Avastin) for breast; FOLFOX (leucovorin, fluorouracil [5-FU], and oxaliplatin) or FOLFIRI (leucovorin, 5-FU, and irinotecan), or variants, plus bevacizumab for colorectal; platinumbased doublet plus bevacizumab for non–small cell lung; paclitaxel/carboplatin plus bevacizumab for ovary; gemcitabine/erlotinib (Tarceva) for pancreas; sunitinib (Sutent) or bevacizumab with or without interferon for renal; and standard guideline-based first-line treatment for other diagnoses.

For the most common predicted tumor types, median overall survival was not reached at more than 24 months for breast cancer (n = 10), while for others was reached at 29.6 months for ovary (n = 10), 15.9 months for non–small cell lung (n�������������������������������� ������������������������������� =������������������������������ ����������������������������� 23), 12.5 months for colorectal (n = 26), 11.7 months for renal (n = 9), 8.4 months for urothelium
(n = 27), 8.2 months for pancreas (n = 12), and 6.8 months for biliary tract cancers (n = 45).
Need for More Evidence? The investigators posed the question of how much additional evidence would be necessary for molecular profiling to be accepted as a standard component of diagnosis for patients with carcinoma of unknown primary. A randomized phase III trial would provide definitive evidence, but such a trial would have inherent difficulties and would require large numbers of patients in order to generate conclusions regarding outcomes for the numerous potential tissues of origin. Moreover, interpretation of such a study would be complicated by the fact that first-line empiric therapy is identical or similar to standard sitespecific therapy for some of the moreresponsive tumor types and that patients who might be expected to benefit from site-specific vs empiric therapy would constitute a minority of the study population. In addition, many patients and physicians may be reluctant to accept randomized assignment to treatment in such a setting. As stated by the investigators, “At this time, we feel that the body of evidence is sufficient to support the use of molecular tumor profiling in the standard management of patients with [carcinoma of unknown primary]. Patients who will benefit most … are those predicted to have treatment-responsive tumor types. With an increasing number of effective molecularly targeted therapies available, an assay prediction may also lead to the identification of additional therapeutic continued on page 54

A sizable percentage of patients with [carcinoma of unknown primary] will not currently benefit from assay-directed therapy, because effective therapy for these tumor types does not currently exist. However, confidence in the assay predictions will allow these patients to receive effective therapy as the standard therapy for these tumor types improves.”

WARNINGS AND PRECAUTIONS: • Treatment with ISTODAX has been associated with thrombocytopenia, leukopenia (neutropenia and lymphopenia), and anemia; therefore, monitor these hematological parameters during treatment with ISTODAX and modify the dose as necessary • Serious and sometimes fatal infections have been reported during treatment and within 30 days after treatment with ISTODAX and the risk of life threatening infections may be higher in patients with a history of extensive or intensive chemotherapy • Electrocardiographic (ECG) changes have been observed with ISTODAX • In patients with congenital long QT syndrome, a history of significant cardiovascular disease, and patients taking anti-arrhythmic medicines or medicinal products that lead to significant QT prolongation, appropriate cardiovascular monitoring precautions should be considered, such as monitoring electrolytes and ECGs at baseline and periodically during treatment • Ensure that potassium and magnesium are within the normal range before administration of ISTODAX • Tumor lysis syndrome has been reported during treatment with ISTODAX. Patients with advanced stage disease and/or high tumor burden should be closely monitored and appropriate precautions taken, and treatment should be instituted as appropriate • ISTODAX may cause fetal harm when administered to a pregnant woman. Advise women to avoid pregnancy while receiving ISTODAX. If this drug is used during pregnancy, or if the patient becomes pregnant while taking ISTODAX, the patient should be apprised of the potential hazard to the fetus (Pregnancy Category D) ADVERSE REACTIONS: Peripheral T-Cell Lymphoma The most common Grade 3/4 adverse reactions (>5%) regardless of causality in Study 3 (n=131) were thrombocytopenia (24%), neutropenia (20%), anemia (11%), asthenia/fatigue (8%), and leukopenia (6%), and in Study 4 (n=47) were neutropenia (47%), leukopenia (45%), thrombocytopenia (36%), anemia (28%), asthenia/fatigue (19%), pyrexia (17%), vomiting (9%), and nausea (6%). Infections were the most common type of serious adverse event reported in Study 3 (n=131) and Study 4 (n=47). In Study 3, 25 patients (19%) experienced a serious infection, including 6 patients (5%) with serious treatment-related infections. In Study 4, 11 patients (23%) experienced a serious infection, including 8 patients (17%) with serious treatment-related infections.

Elekta Receives FDA 510(k) Clearance for Clarity 4D Monitoring
E
lekta has received 510(k) clearance from the FDA for its Clarity 4D Monitoring software, enabling U.S. medical centers to implement a new way of reducing the uncertainty caused by prostate motion during radi-
ation treatment. Physicians will be able to monitor the motion of the prostate and surrounding tissues and organs in real-time and with submillimeter accuracy during the delivery of therapeutic radiation beams.
The ability to continuously visualize the prostate’s precise location constantly during treatment is especially important for clinicians pursuing advanced prostate protocols, such as reduced margin hypofractionated

Clarity a possible ‘game-changer’ is that it’s simple, inexpensive, and will enable real time continuous monitoring of the prostate - increasingly critical as we consider techniques such as hypofractionation, which entails treating patients in shorter therapy courses, but
with longer individual treatments,” says James Wallace, MD, radiation oncologist at Fletcher Allen Health Care in Burlington, Vermont. “We know that the prostate moves during these prolonged treatments and we are going to have to account for it in some way. The capability to observe the prostate from the beginning of the fraction to the end
will be incredibly powerful.” “[The image quality is] remarkably clear compared to other ultrasound technology and in our experience comparable to MRI in terms of our ability to identify structures in the lower pelvis,” he noted. The capability to image anatomy during treatment could provide other

ISTODAX® (romidepsin) for injection For intravenous infusion only The following is a brief summary only; see full prescribing information for complete product information. 1 INDICATIONS AND USAGE ISTODAX is indicated for: • Treatment of cutaneous T-cell lymphoma (CTCL) in patients who have received at least one prior systemic therapy. • Treatment of peripheral T-cell lymphoma (PTCL) in patients who have received at least one prior therapy. These indications are based on response rate. Clinical benefit such as improvement in overall survival has not been demonstrated. 2 DOSAGE AND ADMINISTRATION 2.1 Dosing Information The recommended dose of romidepsin is 14 mg/m2 administered intravenously over a 4-hour period on days 1, 8 and 15 of a 28-day cycle. Cycles should be repeated every 28 days provided that the patient continues to benefit from and tolerates the drug. 2.2 Dose Modification Nonhematologic toxicities except alopecia • Grade 2 or 3 toxicity: Treatment with romidepsin should be delayed until toxicity returns to ≤Grade 1 or baseline, then therapy may be restarted at 14 mg/m2. If Grade 3 toxicity recurs, treatment with romidepsin should be delayed until toxicity returns to ≤Grade 1 or baseline and the dose should be permanently reduced to 10 mg/m2. • Grade 4 toxicity: Treatment with romidepsin should be delayed until toxicity returns to ≤Grade 1 or baseline, then the dose should be permanently reduced to 10 mg/m2. • Romidepsin should be discontinued if Grade 3 or 4 toxicities recur after dose reduction. Hematologic toxicities • Grade 3 or 4 neutropenia or thrombocytopenia: Treatment with romidepsin should be delayed until the specific cytopenia returns to ANC ≥1.5×109/L and/or platelet count ≥75×109/L or baseline, then therapy may be restarted at 14 mg/m2. • Grade 4 febrile (≥38.5°C) neutropenia or thrombocytopenia that requires platelet transfusion: Treatment with romidepsin should be delayed until the specific cytopenia returns to ≤Grade 1 or baseline, and then the dose should be permanently reduced to 10 mg/m2. 2.3 Instructions for Preparation and Intravenous Administration ISTODAX should be handled in a manner consistent with recommended safe procedures for handling cytotoxic drugs. 5 WARNINGS AND PRECAUTIONS 5.1 Hematologic Treatment with ISTODAX can cause thrombocytopenia, leukopenia (neutropenia and lymphopenia), and anemia; therefore, these hematological parameters should be monitored during treatment with ISTODAX, and the dose should be modified, as necessary [See Dosage and Administration (2.2) and Adverse Reactions (6)]. 5.2 Infection Serious and sometimes fatal infections, including pneumonia and sepsis, have been reported in clinical trials with ISTODAX. These can occur during treatment and within 30 days after treatment, and the risk of life threatening infections may be higher in patients with a history of extensive or intensive chemotherapy [See Adverse Reactions (6)]. 5.3 Electrocardiographic Changes Several treatment-emergent morphological changes in ECGs (including T-wave and ST-segment changes) have been reported in clinical studies. The clinical significance of these changes is unknown [See Adverse Reactions (6)]. In patients with congenital long QT syndrome, patients with a history of significant cardiovascular disease, and patients taking anti-arrhythmic medicines or medicinal products that lead to significant QT prolongation, appropriate cardiovascular monitoring precautions should be considered, such as the monitoring of electrolytes and ECGs at baseline and periodically during treatment. Potassium and magnesium should be within the normal range before administration of ISTODAX [See Adverse Reactions (6)]. 5.4 Tumor Lysis Syndrome Tumor lysis syndrome (TLS) has been reported to occur in 1% of patients with tumor stage CTCL and 2% of patients with Stage III/IV PTCL. Patients
advantages as well, according to Di Yan, DSc, Chief Physicist at William Beaumont Hospital in Royal Oak, Michigan. “We have been interested in developing methods for adaptive therapy for a while now,” he says. “The missing link has been the anatomical information from a continuous imaging
with advanced stage disease and/or high tumor burden should be closely monitored, appropriate precautions should be taken, and treatment should be instituted as appropriate. 5.5 Use in Pregnancy There are no adequate and well-controlled studies of ISTODAX in pregnant women. However, based on its mechanism of action and findings in animals, ISTODAX may cause fetal harm when administered to a pregnant woman. In an animal reproductive study, romidepsin was embryocidal and resulted in adverse effects on the developing fetus at exposures below those in patients at the recommended dose of 14 mg/m2/week. If this drug is used during pregnancy, or if the patient becomes pregnant while taking ISTODAX, the patient should be apprised of the potential hazard to the fetus [See Use in Specific Populations (8.1)]. 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 practice. Cutaneous T-Cell Lymphoma The safety of ISTODAX was evaluated in 185 patients with CTCL in 2 single arm clinical studies in which patients received a starting dose of 14 mg/m2. The mean duration of treatment in these studies was 5.6 months (range: <1 to 83.4 months).

Continuous Target Visualization 4D monitoring of the prostate with Clarity during treatment offers continuous tracking of the target and imaging
of the surrounding anatomy, including the bladder, rectum and penile bulb, the latter thought to be responsible for erectile function. Clearly visualizing these structures during treatment could enable clinicians to create plans with tighter margins around intended targets, thereby minimizing radiation exposure to healthy tissue.
Serious Adverse Reactions Infections were the most common type of SAE reported in both studies with 8 patients (8%) in Study 1 and 26 patients (31%) in Study 2 experiencing a serious infection. Serious adverse reactions reported in > 2% of patients in Study 1 were sepsis and pyrexia (3%). In Study 2, serious adverse reactions in > 2% of patients were fatigue (7%), supraventricular arrhythmia, central line infection, neutropenia (6%), hypotension, hyperuricemia, edema (5%), ventricular arrhythmia, thrombocytopenia, nausea, leukopenia, dehydration, pyrexia, aspartate aminotransferase increased, sepsis, catheter related infection, hypophosphatemia and dyspnea (4%). Most deaths were due to disease progression. In Study 1, there were two deaths due to cardiopulmonary failure and acute renal failure. In Study 2, there were six deaths due to infection (4), myocardial ischemia, and acute respiratory distress syndrome. Discontinuations Discontinuation due to an adverse event occurred in 21% of patients in Study 1 and 11% in Study 2. Discontinuations occurring in at least 2% of patients in either study included infection, fatigue, dyspnea, QT prolongation, and hypomagnesmia. Peripheral T-Cell Lymphoma The safety of ISTODAX was evaluated in 178 patients with PTCL in a sponsor-conducted pivotal study (Study 3) and a secondary NCI-sponsored study (Study 4) in which patients received a starting dose of 14 mg/m2. The mean duration of treatment and number of cycles in these studies were 5.6 months and 6 cycles.

Clarity 4D Monitoring uses Autoscan acquisition technology, which robotically acquires live transperineal ultrasound images of soft tissue anatomy from the linear accelerator control area. It is a comfortable, noninvasive imaging procedure that does not involve any extra radiation dose and does not require the use of implanted markers. n
Serious Adverse Reactions Infections were the most common type of SAE reported. In Study 3, 25 patients (19%) experienced a serious infection, including 6 patients (5%) with serious treatment-related infections. In Study 4, 11 patients (23%) experienced a serious infection, including 8 patients (17%) with serious treatment-related infections. Serious adverse reactions reported in ≥ 2% of patients in Study 3 were pyrexia (7%), pneumonia, sepsis, vomiting (5%), cellulitis, deep vein thrombosis, (4%), febrile neutropenia, abdominal pain (3%), chest pain, neutropenia, pulmonary embolism, dyspnea, and dehydration (2%). In Study 4, serious adverse reactions in ≥ 2 of patients were pyrexia (17%), aspartate aminotransferase increased, hypotension (13%), anemia, thrombocytopenia, alanine aminotransferase increased (11%), infection, dehydration, dyspnea (9%), lymphopenia, neutropenia, hyperbilirubinemia, hypocalcemia, hypoxia (6%), febrile neutropenia, leukopenia, ventricular arrhythmia, vomiting, hypersensitivity, catheter related infection, hyperuricemia, hypoalbuminemia, syncope, pneumonitis, packed red blood cell transfusion, and platelet transfusion (4%). Deaths due to all causes within 30 days of the last dose of ISTODAX occurred in 7% of patients in Study 3 and 17% of patients in Study 4. In Study 3, there were 5 deaths unrelated to disease progression that were due to infections, including multi-organ failure/sepsis, pneumonia, septic shock, candida sepsis, and sepsis/cardiogenic shock. In Study 4, there were 3 deaths unrelated to disease progression that were due to sepsis, aspartate aminotransferase elevation in the setting of Epstein Barr virus reactivation, and death of unknown cause. Discontinuations Discontinuation due to an adverse event occurred in 19% of patients in Study 3 and in 28% of patients in Study 4. In Study 3, thrombocytopenia and pneumonia were the only events leading to treatment discontinuation in at least 2% of patients. In Study 4, events leading to treatment discontinuation in ≥ 2 patients were thrombocytopenia (11%), anemia, infection, and alanine aminotransferase increased (4%). 6.2 Postmarketing Experience No additional safety signals have been observed from postmarketing experience. 7 DRUG INTERACTIONS 7.1 Coumadin or Coumadin Derivatives Prolongation of PT and elevation of INR were observed in a patient receiving ISTODAX concomitantly with warfarin. Although the interaction potential between ISTODAX and Coumadin or Coumadin derivatives has not been formally studied, physicians should carefully monitor PT and INR in patients concurrently administered ISTODAX and Coumadin or Coumadin derivatives [See Clinical Pharmacology (12.3)]. 7.2 Drugs that Inhibit or Induce Cytochrome P450 3A4 Enzymes Romidepsin is metabolized by CYP3A4. Although there are no formal drug interaction studies for ISTODAX, strong CYP3A4 inhibitors (e.g., ketoconazole, itraconazole, clarithromycin, atazanavir, indinavir, nefazodone, nelfinavir, ritonavir, saquinavir, telithromycin, voriconazole) may increase concentrations of romidepsin. Therefore, co-administration with strong CYP3A4 inhibitors should be avoided if possible. Caution should be exercised with concomitant use of moderate CYP3A4 inhibitors. Co-administration of potent CYP3A4 inducers (e.g., dexamethasone, carbamazepine, phenytoin, rifampin, rifabutin, rifapentine, phenobarbital) may decrease concentrations of romidepsin and should be avoided if possible. Patients should also refrain from taking St. John’s Wort. 7.3 Drugs that Inhibit Drug Transport Systems Romidepsin is a substrate of the efflux transporter P-glycoprotein (P-gp, ABCB1). If ISTODAX is administered with drugs that inhibit P-gp, increased concentrations of romidepsin are likely, and caution should be exercised. 8 USE IN SPECIFIC POPULATIONS 8.1 Pregnancy Pregnancy Category D [See Warnings and Precautions (5.5)]. There are no adequate and well-controlled studies of ISTODAX in pregnant women. However, based on its mechanism of action and findings in animals, ISTODAX may cause fetal harm when administered to a pregnant woman. In an animal reproductive study, romidepsin was embryocidal and resulted in adverse effects on the developing fetus at exposures below those in patients at the recommended dose. If this drug is used during pregnancy, or if the patient becomes pregnant while taking ISTODAX, the patient should be apprised of the potential hazard to the fetus. Romidepsin was administered intravenously to rats during the period of organogenesis at doses of 0.1, 0.2, or 0.5 mg/kg/day. Substantial resorption or post-implantation loss was observed at the high-dose of 0.5 mg/kg/day, a maternally toxic dose. Adverse embryo-fetal effects were noted at romidepsin doses of ≥0.1 mg/kg/day, with systemic exposures Cosmos Communications 718.482.1800

FDA Update
FDA Expands Abiraterone’s Use for Late-stage Prostate Cancer
I
n December, the FDA approved an expanded indication for abiraterone acetate (Zytiga) in combination with prednisone for the treatment of patients with metastatic castration-resistant prostate cancer.
Trial Design The approval was based on a trial randomly assigning patients with metastatic castration-resistant prostate cancer who had not received cytotoxic chemotherapy to either abiraterone acetate plus pred-
(AUC) ≥0.2% of the human exposure at the recommended dose of 14 mg/m2/week. Drug-related fetal effects consisted of folded retina, rotated limbs, and incomplete sternal ossification. 8.3 Nursing Mothers It is not known whether romidepsin 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 ISTODAX, a decision should be made whether to discontinue nursing or discontinue the drug, taking into account the importance of the drug to the mother. 8.4 Pediatric Use The safety and effectiveness of ISTODAX in pediatric patients has not been established. 8.5 Geriatric Use Of the approximately 300 patients with CTCL or PTCL in trials, about 25% were > 65 years old. No overall differences in safety or effectiveness were observed between these subjects and younger subjects; however, greater sensitivity of some older individuals cannot be ruled out. 8.6 Hepatic Impairment No dedicated hepatic impairment study for ISTODAX has been conducted. Mild hepatic impairment does not alter pharmacokinetics of romidepsin based on a population pharmacokinetic analysis. Patients with moderate and severe hepatic impairment should be treated with caution [See Clinical Pharmacology (12.3)]. 8.7 Renal Impairment No dedicated renal impairment study for ISTODAX has been conducted. Based upon the population pharmacokinetic analysis, renal impairment is not expected to significantly influence drug exposure. The effect of end-stage renal disease on romidepsin pharmacokinetics has not been studied. Thus, patients with end-stage renal disease should be treated with caution [See Clinical Pharmacology (12.3)]. 10 OVERDOSAGE No specific information is available on the treatment of overdosage of ISTODAX. Toxicities in a single-dose study in rats or dogs, at intravenous romidepsin doses up to 2.2 fold the recommended human dose based on the body surface area, included irregular respiration, irregular heart beat, staggering gait, tremor, and tonic convulsions. In the event of an overdose, it is reasonable to employ the usual supportive measures, e.g., clinical monitoring and supportive therapy, if required. There is no known antidote for ISTODAX and it is not known if ISTODAX is dialyzable. 13 NONCLINICAL TOXICOLOGY 13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility Carcinogenicity studies have not been performed with romidepsin. Romidepsin was not mutagenic in vitro in the bacterial reverse mutation assay (Ames test) or the mouse lymphoma assay. Romidepsin was not clastogenic in an in vivo rat bone marrow micronucleus assay when tested to the maximum tolerated dose (MTD) of 1 mg/kg in males and 3 mg/kg in females (6 and 18 mg/m2 in males and females, respectively). These doses were up to 1.3-fold the recommended human dose, based on body surface area.

16 HOW SUPPLIED/STORAGE AND HANDLING Keep out of reach of children. Procedures for proper handling and disposal of anticancer drugs should be considered. Several guidelines on this subject have been published1-4 [See References (15)]. 17 PATIENT COUNSELING INFORMATION See FDA-approved patient labeling. 17.1 Instructions • Nausea and Vomiting Nausea and vomiting are common following treatment with ISTODAX. Prophylactic antiemetics are recommended to be used in all patients. Advise patients to report these symptoms so that appropriate treatment can be instituted [See Adverse Reactions (6)]. • Low Blood Counts Patients should be informed that treatment with ISTODAX can cause low blood counts and that frequent monitoring of hematologic parameters is required. Patients should be instructed to report fever or other signs of infection, significant fatigue, shortness of breath, or bleeding [See Warnings and Precautions (5.1)]. • Infections Patients should be informed that infections may occur during treatment with ISTODAX. Patients should be instructed to report fever, cough, shortness of breath with or without chest pain, burning on urination, flu-like symptoms, muscle aches, or worsening skin problems [See Warnings and Precautions (5.2)]. • Tumor Lysis Syndrome Patients at risk of tumor lysis syndrome (i.e, those with advanced stage disease and/or high tumor burden) should be monitored closely for TLS and appropriate measures taken if symptoms are observed [See Warnings and Precautions (5.4)]. • Use in Pregnancy If pregnancy occurs during treatment with ISTODAX, female patients should be advised to seek immediate medical advice and counseling. [See Warnings and Precautions (5.5)]. • Patients should be instructed to read the patient insert carefully.

Based on non-clinical findings, male and female fertility may be compromised by treatment with ISTODAX. In a 26-week toxicology study, romidepsin administration resulted in testicular degeneration in rats at 0.33 mg/kg/dose (2 mg/m2/dose) following the clinical dosing schedule. This dose resulted in AUC0-inf. values that were approximately 2% the exposure level in patients receiving the recommended dose of 14 mg/m2/dose. A similar effect was seen in mice after 4 weeks of drug administration at higher doses. Seminal vesicle and prostate organ weights were decreased in a separate study in rats after 4 weeks of daily drug administration at 0.1 mg/kg/day (0.6 mg/m2/day), approximately 30% the estimated human daily dose based on body surface area. Romidepsin showed high affinity for binding to estrogen receptors in pharmacology studies. In a 26-week toxicology study in rats, atrophy was seen in the ovary, uterus, vagina and mammary gland of females administered doses as low as 0.1 mg/kg/dose (0.6 mg/m2/dose) following the clinical dosing schedule. This dose resulted in AUC0-inf. values that were 0.3% of those in patients receiving the recommended dose of 14 mg/m2/dose. Maturation arrest of ovarian follicles and decreased weight of ovaries were observed in a separate study in rats after four weeks of daily drug administration at 0.1 mg/kg/day (0.6 mg/m2/day). This dose is approximately 30% the estimated human daily dose based on body surface area.

tients had a prior orchiectomy or continued to receive a gonadotropin-releasing hormone analog. The coprimary endpoints were radiographic progression-free survival and
overall survival. Treatment with abiraterone acetate improved radiographic progression-free survival. The median radiographic progression-free survival was 8.3 months in the placebo arm and had not yet been reached for those receiving abiraterone acetate (HR = 0.43 [95% CI = 0.35–0.52], P < .0001]. At the prespecified third interim analysis, median overall survival was 35.3 and 30.1 months in the abiraterone acetate and placebo arms, respectively (HR = 0.79 [95% CI = 0.66–0.96]). These results did not cross the O’Brien-Fleming boundary for statistical significance. The primary endpoints were supported by statistically significant improvements in time to opiate use and time to cytotoxic chemotherapy.
Safety Data Safety data were evaluated in 1,333 patients with metastatic castration-resistant prostate cancer who received abiraterone acetate plus prednisone and in 934 patients who received placebo plus prednisone in this and the other pivotal trial. The most common (≥10%) adverse reactions included fatigue, joint swelling or discomfort, edema, hot flush, diarrhea, vomiting, cough, hypertension, dyspnea, urinary tract infection, and contusion. The most common laboratory abnormalities (> 20%) included anemia, elevated alkaline phosphatase, hypertriglyceridemia, lymphopenia, hypercholesterolemia, hyperglycemia, elevated AST, hypophosphatemia, elevated ALT, and hypokalemia. The recommended dose and schedule for abiraterone acetate is 1,000 mg administered orally once daily in combination with prednisone 5 mg administered orally twice daily. Abiraterone acetate must be taken on an empty stomach. No food should be consumed for at least 2 hours before and for at least 1 hour after abiraterone acetate. Abiraterone Cmax and AUC0-∞ (exposure) were increased up to 17- and 10-fold higher, respectively, when a single dose of abiraterone acetate was administered with a meal compared to a fasted state. n

ASCO Top Five List Highlighted in IOM Workshop
A
s part of the Institute of Medicine’s (IOM) National Cancer Policy Forum workshop on delivering affordable cancer care in the 21st century, ASCO’s Top Five list was highlighted as an example of a way to improve quality of care for patients while reducing unnecessary costs.

Force, spoke about the Top Five list and its impact on improving value and quality of cancer care. “Physicians inherently want to do the right thing. Part of that means not performing medical tests or treatments that have little or no clinical benefit,” Dr. Schnipper said. “Guidance like that provided by ASCO’s Top Five list also helps physicians in the exam rooms when discussing treatment options with patients.” Additionally, Dr. Schnipper highlighted the work of a Cost of Cancer Care Task Force policy statement that encourages physicians to address financial concerns and burdens with their patients. “We set out with one initial principle in mind: The cost of cancer care should be a part of routine interaction

with patients, giving the growing burden many of them are facing,” he said.
Evaluating the Impact Dr. Schnipper also emphasized the need to measure and evaluate the impact of ASCO’s Top Five list. To that end, ASCO is currently planning on incorporating the Top Five list items into its measures set as part of the Quality Oncology Practice Initiative® to demonstrate physician behavior and uptake of the Top Five list recommendations. Ezekiel Emanuel, MD, of the University of Pennsylvania School of Medicine, praised ASCO’s efforts on the Top Five list and called on the Society to continue adding to its list.

New ASCO Statement Outlines Agenda to Advance Cancer Survivorship Care
I
n response to the needs of a growing population of cancer survivors, ASCO has released a position statement, recently published online in the Journal of Clinical Oncology. Developed through the work of the ASCO Cancer Survivorship Committee, the statement outlines a comprehensive agenda for achieving high-quality cancer survivorship care. Improvements in early detection of first malignancies and the development of effective therapies have contributed to a dramatic increase in cancer survivors, who are at increased risk for long-term morbidity and premature mortality. These individuals’ cancer-related follow-up care needs extend beyond surveillance for cancer recurrence. As a result, the ASCO statement outlines a comprehensive approach to survivorship care that incorporates general health promotion, primary and secondary cancer prevention, and symptom management of common long-term and late effects.
Melissa Hudson, MD
According to Melissa Hudson, MD, Immediate Past-Chair of the Survivorship Committee and Director of the Cancer Survivorship Division at St. Jude Children’s Research Hospital, “ASCO’s goal is to develop tools and facilitate the development of infrastructure that will help its members determine how survivorship care can be optimally integrated within their current practice standards.”
Developing Clinical Guidance A major area gap in survivorship care today is the availability of clinical guidelines on the longterm clinical management of survi-

vors of adult-onset cancer. Limited research in adult-onset cancer late effects requires extrapolation from other populations to identify effective screening and treatment methods, said Smita Bhatia, MD, ASCO Cancer Survivorship Committee Member and Associate Director of Population Sciences at City of Hope Comprehensive Cancer Center. She added that the resulting consensusbased recommendations will be developed using a modified Delphi approach. “It’s a bit more challenging to [develop guidance] within the context of the heterogeneity of adult-onset malignancies,” compared with the pediatric cancer patient population, said Dr. Hudson. “We should be drawing upon the expertise of leaders in the survivorship field to develop clinical consensus-based guidance to serve the needs of the current patients,” which, said Dr. Hudson, will also help identify important areas for research. To address this need, ASCO has begun work on developing guidelines on the management of late- and long-term effects, through collaboration between the Cancer Survivorship and Clinical Practice Guidelines committees. The focus of these guidelines will be on common symptoms or clinical issues that reach across a diversity of cancer types. The first three guidelines— slated for completion this spring— will address fatigue, neuropathy, and depression.
Expanding Research Initiatives To strengthen the foundation for such clinical guidelines, ASCO is also working to in-
crease “the quality of evidence, the abundance of evidence, [and] the robustness of evidence in survivorship care,” according to Gregory Reaman, MD, member of ASCO’s Survivorship Committee and Associate Director in the FDA’s Office of Hematology and Oncology Products. He noted that, as a first step toward identifying knowledge gaps, ASCO recently undertook a survey to develop an inventory of existing research initiatives and activities. Combined with a literature review and an assessment of survivorship research activities at cancer centers designated by the National Cancer Institute (NCI), the survey data will facilitate the prioritization of future research efforts.
Gregory Reaman, MD
Noting that economic constraints are an obstacle to the development of such studies, Dr. Reaman says that ASCO plans to advocate for the prioritization of existing resources for survivorship research initiatives. Most notably, in its statement ASCO encourages the NCI to incorporate survivorship-related data elements into the current redesign and reorganization of its clinical trial infrastructure, which will have “profound implications” for advancing survivorship research, according to Dr. Reaman. Given the resource limitations, another goal articulated in the statement is to leverage innovative clinical research methods, such as the collection of self-reported data from study participants or the use of a uniform treatment summary, completed at the end of protocol therapy. Such approaches could limit the burden of “adding yet another layer on already

stressed investigators and an already stressed infrastructure,” Dr. Reaman said.
Improving Care Coordination Meanwhile, recognizing that optimal survivorship care will require a multidisciplinary care infrastructure, ASCO is also evaluating models of survivorship care and methods to optimize the transition of patients between oncology and primary care providers (PCPs). “With the burgeoning number of cancer survivors and the burgeoning number of visits needed for acute therapy…we don’t have the space for oncologists to be following [all of] these patients for life,” said Kevin Oeffinger, MD, ASCO Cancer Sur-

cer center or by an oncology practice.” A patient with a low risk of cancer recurrence and a low risk of late effects who is psychosocially stable likely will receive adequate follow-up care from a PCP, through coordination with the patient’s oncologist. Even the highrisk patient needs to be followed by a PCP for non-cancer and non-cancer therapy needs, he added. ASCO strongly supports the position that effective communication between the oncologist and the PCP is essential to ensure that the cancer survivor receives appropriate long-term follow-up care in the primary care setting based on the patient’s risk profile. This requires the oncologist to provide information—in the form of a treatment summary and care plan—that “demystifies the cancer experience.” He added that such information should be presented in an easy-to-read format that outlines the three to five key clinical issues to monitor in the patient. ASCO’s websites offers both oncologists and patients access to treatment summary and survivor-

ship care plan templates to help provide a roadmap for managing care following active treatment.
Advocating for Policy Change In an effort to encourage systemwide change during these fiscally uncertain times, ASCO advocates for leveraging existing legislation to support initiatives to improve cancer survivorship care quality, while ensuring that all patient have access to adequate and affordable coverage. This includes continued support of legislation aimed at comprehensive care coordination, such as provisions of the Affordable Care Act like accountable care organizations and medical homes; working within the framework of
essential health benefits to define and advocate for services essential to cancer survivors; pushing for inclusion of survivorship in the development of national and state cancer control plans; and increasing policymaker awareness of cancer survivorship issues.
Mary McCabe, RN, MA, Director of Memorial Sloan-Kettering’s Cancer Survivorship Program and ASCO Cancer Survivorship Committee Chair, said, “Our goal in developing this survivorship agenda is to provide guidance that will assist the oncology community’s efforts to
ensure that all cancer survivors receive coordinated care that includes the full range of services necessary to assure the highest quality of life possible.” n © 2013. American Society of Clinical Oncology. All Rights Reserved.

Community Research Forum Addresses Conundrums Common to Community Practices that Conduct Research Quality assessment and staff workload the focus at inaugural meeting
I
t is every research site’s biggest concern. The National Cancer Institute (NCI), the FDA, or drug company sponsors could arrive at any time to comb through a site’s documents related to a specific trial. It’s called an audit, and it’s common. And yet, not all sites that conduct research have proactive quality assurance initiatives in place to keep them audit-ready. Many, it turns out, are just not sure how to develop and launch an internal quality assessment program. Or they feel they don’t have the time or resources.
ment of a variety of research programs.
Quality Assurance Manual
The meeting agenda included a representative from the NCI who told attendees what the agency scrutinizes when auditing a clinical research site, including how variations are scored and what those scores mean. “That really helped define the need for maintaining a quality program in your clinical research program,” said Thomas A. Marsland, MD, MPH, a medical oncologist practicing at the Cancer Specialists of North Florida, who leads the ASCO workgroup developing a manual to help community research sites develop a quality assurance program. The workgroup plans to complete the manual by next year’s meeting. Attendees at this year’s meeting discussed the possibility of a research comMarge Good, RN, BSN, MPH ponent being added to Thomas A.

Once complete, this community sites for the quality assess-
instrument will allow community practices to ascertain the clinical workload associated with individual trials. Developing a “formula” for workload is currently a challenging problem, as clinical trials can range from relatively simple and quick to extremely complicated and time-consuming for staff. Judging workload simply by the number of patients recruited—a typical method—is a highly flawed approach, said Marge Good, RN, BSN, MPH, a nurse consultant in the NCI Division of Cancer Prevention and the leader of the ASCO workgroup developing the workload assessment tool. “Practices have staff that often come to the manager and say, ‘We’re so busy, we’re dying.’ But there’s really no metric for practice managers to compare what their staff is doing with what other practices’ staffs are doing, and say, ‘Yes you are,’ or ‘No, you’re not,’” said Ms. Good. At the meeting, attendees discussed workload issues and considered a number of workload assessment tools. They concluded that the tool developed by Ms. Good in her many years as Administrative Director of Wichita Community Clinical Oncology Program was the most practical and meaningful. Ms. Good explained that the tool is a simple, easy-to-use system that she utilized to collect 10 years of data on trial acuity. From these data, practice leaders were better able to observe how staff members were using their time and to
subsequently balance workloads and hire appropriate staff for the research protocols they were maintaining. The workload assessment group plans to launch a pilot of the tool with many community practices in spring 2013 and present the tool at next year’s Forum meeting.
New Projects to be Launched at Next Year’s Meeting The overall goal of the Forum is to produce helpful tools that will keep research quality high and assist community sites engaged in research. In the coming year the Community Research Forum Planning Committee will discuss additional project concepts that address crosscutting challenges to conducting research in the community setting. The Forum will initiate projects to address these challenges at the 2013 meeting. After all, said Dr. Marsland, with health-care reform upon us—not to mention multiple market-driven changes in research—ASCO wants to be at the forefront of the drive for quality. “It’s important that ASCO define quality and become the voice for quality that is heard loud and clear,” he said. “This role is valid for research and ties in well with ASCO’s many activities and initiatives to promote quality across the whole spectrum of cancer care.” n © 2013.

ASCO Report Encourages Further Discussion to Improve REMS Development, Communication
T
he oncology community—including providers, patients, and industry—and the FDA should continue to work together to improve the agency’s Risk Evaluation and Mitigation Strategies (REMS) program, according to the report of the ASCO REMS Working Group published online by the Journal of Oncology Practice. “Our report notes that oncology REMS programs should supplement, not duplicate, the education, experience and clinical tools that provid-
ers already have for managing safety concerns,” said James N. Frame, MD, FACP, Chair of ASCO’s REMS Working Group. “The FDA has proposed some meaningful steps to improve the REMS programs. ASCO is eager and well-positioned to work with the agency and drug manufacturers to build on the opportunity to improve care for our patients.” The report summarizes an ASCO-hosted workshop in 2011. It also highlights ongoing oncology community activities and several
FDA actions to accomplish the goals of promoting safe use of oncology products and addressing the challenges of REMS programs. On July 27, 2011, oncologists, hematologists, oncology nurses, pharmacists, patient advocates, the pharmaceutical industry, and FDA officials came together to address oncology community stakeholder concerns and to discuss possible alternative approaches for the management of certain oncology and hematology drugs with REMS reporting requirements. Providers and
the FDA share a common goal of ensuring that cancer patients receive safe and effective care, but experience with the REMS programs has demonstrated that some aspects of the programs do not enhance and sometimes detract from patient care.

Online Prostate Cancer Information Is Written at Reading Levels above Many Americans’ Literacy Skills A Conversation with Gopal Gupta, MD By Jo Cavallo
level, far beyond the literacy skills of many patients. The ASCO Post recently talked with Dr. Gupta about the results of his study and what oncologists can do to help direct their patients with cancer to more accessible health material, both on the Internet and in print.
Study Methods
Gopal Gupta, MD
A
lthough 61% of Americans are going online to access health information,1 many of them may not understand what they find there, including information about prostate cancer treatment options. According to a new study published in The Journal of Urology,2 as many as 90 million Americans have literacy skills below a high school reading level. However, an examination by the study authors of 62 websites catering to prostate cancer and its treatment options found that only 3 were written below a 9th-grade reading level. The result, said study senior author Gopal Gupta, MD, Instructor in Urology and Surgery, Loyola University Medical Center in Maywood, Illinois, is that patients with prostate cancer who have education levels below the 9th grade may be more likely to misunderstand the information they read about their cancer, jeopardizing access to their best treatment options and limiting their ability to participate in the shared decisionmaking process. While the National Institutes of Health (NIH) recommends that physicians and health-care organizations use patient education material written at a 4th through 6th grade reading level, online health information, even at many common consumer medical sites such as WebMD, is often written well above those levels. In fact, Dr. Gupta and his colleagues found that even the American Urological Association Foundation’s website uses prostate cancer treatment information written above the 12th grade reading
How did you find the websites you examined in your study? First, we identified the three most common keywords from over 500 terms related to prostate cancer treatment options. They were “robotic prostatectomy,” “prostate cancer,” and “prostate cancer treatment.” Then we sorted through 270 websites from the top three search engines, excluding any that were non-English and not primarily text (such as YouTube videos). We also removed any sites that appeared as
different options. That led us to look for some way we could supplement these meetings using written materials that patients and their spouses could find online. They could print out these materials to read at their leisure. It was shocking to us that 95% of the websites we analyzed were written above the NIH recommended fourth to sixth grade reading level.
Study Implications What are some of the ramifications of patients with prostate cancer not understanding the information they find online? There are many ramifications. The number 1 goal of providing health information is to better inform patients about their disease and treatment options. One question is what if the different treatment options presented online have different
Oncologists need to be aware of the readability level of the [patient education material they provide] and how much the patient will likely be able to understand from the information. —Gopal Gupta, MD
banner advertisements. The remaining 62 websites were then categorized by source, such as government, academic practice, nonacademic practice, commercial, nonprofit, news, and health. To assess the readability of the sites, we used the Flesch-Kincaid grade level and the Flesch reading ease level. To our dismay, we found that only 3 of the 62 websites were written below a high school reading level.
Many Treatment Options Why did you decide to undertake this study? Prostate cancer is the most common cancer among men in the United States, and there are many treatment options. Our study stemmed from the realization that presenting so many options to patients often left them befuddled about what to do and left practitioners exhausted because they have to explain all the
levels of readability. Furthermore, what if there is a bias inherent in the writing? For example, if all options are equivalent in predicted outcome but the information is presented in numerical order, this may bias a patient’s ability to make an informed decision. Let’s say that in an online discussion of the four treatment options for prostate cancer—active surveillance, robotic prostatectomy, radiation beam therapy, and radiation seed therapy—the material about active surveillance is written at a higher level of understanding then the section on surgery. That could influence the choice of patients reading the information. In addition, the concept of active surveillance can be difficult to explain (and hard for the patient to understand). The idea of having cancer and not actively doing something about it
is a tricky concept for many patients. They have to be willing to participate in ongoing surveillance and trust their physicians as well as the basic principle of having what appears to be a lowgrade cancer that we will continue to watch so we can avoid the downside of committing to immediate therapy. But that’s a tough conversation.
Impact on Practice Have your study findings changed the way you approach discussions with your patients with prostate cancer? As physicians, our job is to do the right thing for our patients and support them in their decision-making process. I don’t want to confuse patients without even knowing it. I’m very careful about the supplemental reading material I hand out or the online resources I recommend to patients for further reading about their prostate cancer diagnosis. I generally use the National Comprehensive Cancer Network (NCCN) Guidelines for Patients (nccn.com), but even that information is written at a 7th to 8th grade reading level, so it is probably above the comprehension of some patients. I’ve also instituted a multidisciplinary approach in my practice, whereby specific experts in radiotherapy, chemotherapy, and surgery present the different treatment options to the patient. So patients with newly diagnosed prostate cancer will meet separately with the surgeon, the radiation oncologist, and me. That way the patient can immediately contrast options, meet with the providers to ask questions, and make a better-informed decision. Our study also found that patients with low-health literacy may not understand even commonly used words such as “erection” and “impotence.” In those cases, you need to use simpler terminology, or define terms as you use them.

Lumpectomy Rates Inconsistent with Response Rates in Early Breast Cancer By Caroline Helwick
A
chieving a pathologic complete response to neoadjuvant chemotherapy does not always reduce the aggressiveness of breast cancer surgery, according to an analysis of the NeoALLTO trial presented at the 2012 European Society for Medical Oncology (ESMO) Congress in Vienna.1
Carmen Criscitiello, MD
Carmen Criscitiello, MD, of the European Institute of Oncology in Milan, Italy, and colleagues determined which factors influenced the type of surgery (mastectomy or lumpectomy) offered to the 429 patients with HER2-positive breast cancer who underwent breast surgery after receiving neoadjuvant therapy within the NeoALTTO trial. “Apparently, the final decision on the type of surgery was mainly based on characteristics observed before therapy,” Dr. Criscitiello noted. “Surgeons and medical oncologists should focus, however, on the characteristics observed after treatment, with discussions occurring in a multidisciplinary way before final decisions are made.”
Surgery after Neoadjuvant Treatment in Breast Cancer ■■ In the NeoALLTO trial of patients with HER2-positive early breast cancer,
achievement of pathologic complete response did not fully correlate with breast-conserving surgery.
■■ Type of surgery planned at diagnosis heavily influenced the surgery performed after neoadjuvant chemotherapy.
■■ Clinicians should not entirely rely on pretreatment characteristics when
choosing between mastectomy and breast-conserving surgery, but they should carefully focus on the response achieved to systemic therapy.
Findings from NeoALLTO NeoALLTO investigators previously reported that the combination of paclitaxel, lapatinib (Tyekrb), and trastuzumab (Herceptin) significantly increased the pathologic complete response rate compared to paclitaxel
EXPERT POINT OF VIEW
I
nvited discussant Ian Smith, MD, of The Royal Marsden Hospital and Institute of Cancer Research in London, commented at the ESMO meeting that while all three arms of NeoALLTO, especially the arm with dual HER2 blockade, achieved good pathologic complete response rates, “the breast-conserving surgery rate is perhaps disappointingly low, so we are getting better [pathologic complete response rates] but no additional gains regarding the surgery.” He said the finding that estrogen receptor (ER) negativity was used as a reason to avoid lumpectomy is “particularly disappointing, since ER-negative HER2-positive tumors have the best chance for a [pathologic complete response]—60% or greater.” Dr. Smith noted that in the GeparQuattro study, which involved 445 HER2-positive women treated with trastuzumab and chemother-

apy, the pathologic complete response rate was 32% and the breastconservation rate was 63%.1 The reason for the higher rate of conservative surgery, he suggested, “could be that the trials’ surgeons were experienced in, and committed to, the neoadjuvant approach.” Nevertheless, he added, of 154 patients who had mastectomy, 21% had achieved a pathologic complete response; so even in this study the results were not optimal. Part of the problem, he added, is that “the surgeon doesn’t know it’s a [pathologic complete response] until after the surgery.” An understanding of the short-term changes in molecular markers may help better predict who really needs mastectomy, he said. Finally, Dr. Smith concluded, to achieve one of the goals in breast cancer care—to treat effectively while limiting morbidity—“we must train
It is important for oncologists to examine what is in the patient education material they give out in their clinics and practices and on the websites they recommend. Oncologists need to be aware of the readability level of the material and how much the patient will likely be able to understand from the information.

combined with either drug alone.2 Several international expert panels have recommended that the rate of breast-conserving surgery should increase in patients who respond well to neoadjuvant treatment, as was seen in this trial, Dr. Criscitiello said. But while the pathologic complete response rate was 51.3% with the dual HER2 blockade, breastconserving surgery was performed on only 41.4% of women. Regardless of which treatment the women received, breast-conserving surgery rates hovered around 40%, Dr. Criscitiello reported. “The experimental treatment with paclitaxel plus lapatinib and trastuzumab within the NeoALTTO trial nearly doubled the rate of pathologic complete response compared to treatment with paclitaxel combined with either drug alone,” she said. “However, this successful result did not translate into a higher rate of breast-conserving surgery.”
Factors Influencing Type of Surgery Several factors were found to be related to choice of surgery after systemic therapy, most notably the surgical plan at diagnosis. If breast-conserving surgery was planned in advance, 74% underwent it. On the other hand, 30% of patients initially considered inoperable or requiring mastectomy had References 1.

35th ESMO Congress breast-conserving surgery. Larger tumor size at diagnosis also influenced the type of planned surgery. “Indeed, we saw that tumor characteristics prior to neoadjuvant therapy play a main role in deciding the type of surgery, irrespective of the response to given therapies,” Dr. Criscitiello said. “One of the goals of the neoadjuvant therapy concerns increasing the rate of breast conservation, but this goal is clearly not achieved if the type of surgery is chosen according to baseline characteristics.” Geographic region influenced the choice of treatment at baseline, with breast-conserving surgery significantly less common in developing countries compared to developed countries: 32.1% vs 53.2% (P = .006). This probably represents the lack of radiotherapy in poorer countries. Mastectomy is likely the appropriate choice under these circumstances, several breast cancer specialists suggested at the meeting. Several baseline factors influenced the choice of surgery, with conservative surgery significantly

French Investigators Prospectively Test Genomically Driven Treatment in Metastatic Breast Cancer By Caroline Helwick
W
hole-genome DNA analysis prospectively identified alterations in metastatic tumors that could be individually targeted with molecular agents, in a study presented at the 2012 European Society for Medical Oncology (ESMO) Congress by Fabrice André, MD, of Institut Gustave-Roussy, Villejuif, France.1
until they develop progressive disease. To date, only 26 patients have shown disease progression and have been matched with treatment that has included 13 different targeted regimens (single agents or combinations)—often PI3K and Akt inhibitors. Evidence of activity has been noted in eight patients (response or stable disease ≥ 4 months). At a press briefing, co-investigator Monica Arnedos, MD, also of Institut Gustave-Roussy, explained, “Most patients still have no need for treatment, as their disease is controlled, but we expect within 3 years to have treated 80 or more patients.”
Fabrice André, MD
First Study of Its Kind The SAFIR-01 trial is the first large-scale—in fact, countrywide— study to prospectively test the entire genome from a biopsy of a metastatic lesion, then match the alteration with a targeted agent. Currently, most genetic testing looks for specific genetic alterations in a limited number of genes, and thus, many treatment opportunities may be lost, said Dr. André. The study used whole-genome (comparative genomic hybridization) arrays to look at genetic copy numbers (gains and losses), and identified “hot spot” mutations, specifically PIK3CA and Akt mutations, which are common in breast cancer. The investigators were able to perform whole-genome analysis on 251 of 393 patients, of whom 172 (69%) were found to have genetic alterations. While the majority of these involved “druggable” genes that can be targeted by an anticancer drug, about 20% were rare and sometimes unexpected alterations. The common occurrence of these low-frequency alterations “highlights the need for whole-genome approaches,” Dr. André said. In the study, patients with metastatic disease undergo biopsy, but their disease is stable at the time of genetic testing. Therefore, they do not receive mutation-guided therapy
Whole-genome Arrays in Breast Cancer ■■ Whole-genome DNA analysis can prospectively identify alterations in
metastatic breast cancer tumors that can be individually targeted with molecular agents.
■■ Genetic alterations were found in over two-thirds of patients in the French SAFIR-01 trial, and many were rare and unexpected.
■■ Targeted treatment was associated with an early signal of activity. ■■ The technique can also be applied in the neoadjuvant setting, but in a study presented at ESMO it did not lead to higher rates of pathologic complete response.
ter University in Canada suggested there may be another risk associated with genomic-driven treatment. “It is likely that the genetic and molecular abnormalities are very complex, and the assumption that we can implement a targeted approach because we can identify these abnormalities may put patients at risk of passing up standard treatments,” he said. “In some ways, it feels like we are on a rollercoaster that is a little out of control.”
“This is the first prospective trial showing that whole-genome expression array is feasible in the context of daily practice within 15 days,” he said. “Gene-expression arrays could be a solution in the future, an all-in-one assay for personalized medicine.”
Neoadjuvant Setting Monica Arnedos, MD
Listener Concerns Upon the conclusion of Dr. Andre’s presentation, questions from the audience indicated that many oncologists are not yet comfortable with exploring genetic alterations in metastatic lesions. Dr. André noted that 18 patients in the study “could not go to biopsy,” and among “several” adverse events were liver hematomas and pneumothorax. “I prefer to have the final analysis before reporting on these,” he said. “It is becoming common to recommend biopsy at the time of relapse, but I do think we should be comfortable with the adverse event rate. I would like to see a large epidemiologic study of adverse events associated with these biopsies.” Peter Ellis, MBBS, PhD, of McMas-
Peter Ellis, MBBS, PhD
In a separate study led by Dr. André, the investigators reported outcomes using whole-genome expression arrays in the neoadjuvant setting, the aim being to match the neoadjuvant chemotherapy to the genetic profile of the tumor.2 Results of the phase III trial, REMAGUS04, showed no increase

in pathologic complete responses after genetically driven treatment, compared with standard treatment. However, patients with a positive probe were more likely to have disappearance of tumor. Moreover, the study proved that whole-genome expression array testing can be accomplished in the clinical setting; 61% of patients were successfully tested and started on targeted treatment, reported Jean-Yves Pierga, MD, of the Institut Curie, Paris.
Christoph Zielinski, MD
Could Affect Drug Approval ESMO press briefing moderator Christoph Zielinski, MD, of the Medical University of Vienna, Austria, commented that the findings from SAFIR-01 trial suggest the field of oncology will “probably move sooner rather than later from an anatomically oriented drug approval process to one oriented toward signaling pathways.” He noted, “Surprising compounds have emerged that we would never expect to work in certain situations, but due to unsuspected genetic alterations, they do. I think this may change the [drug] registration process.” Meanwhile, he believes whole-genome testing should be restricted to the research setting, and not applied in the clinic. “We still have to prove this is the optimum approach, though … this is an enormously important step forward.” n

Focus on Young Adults
Teens and Young Adults with Cancer Want a Voice in End-of-life Care Having an advance-care planning guide helps patients maintain control and preserve hope, study finds. By Jo Cavallo
A
top the list of concerns of adolescents and young adults with a life-threatening cancer are these two considerations: being able to choose the kind of medical treatment they want (or do not want) and expressing their wishes to family and friends about how they want to be remembered, according to a new study published in the journal Pediatrics.1
Advanced Care Planning The focus of the study was to assess and compare the usefulness of two previously developed advancecare planning guides, My Thoughts, My Wishes, My Voice—a guide prepared specifically for adolescents and young adults—and Five Wishes—an advance-care planning guide for adults. The study researchers asked 52 adolescents and young adults, aged 16 to 28, living with metastatic or recurrent cancer (including leukemia, brain tumors, and sarcomas) or HIV/AIDS, to evaluate pages from both guides and suggest any changes they would like to have in content, design, format, or style. The result is the publication of a new guide, Voicing My Choices™: A Planning Guide for Adolescents & Young Adults, which incorporates topics the study participants said were most important to them, including having input in their medical
I
care and treatment decisions, such as the types of life support treatment they want; how they want to be cared for and supported during their illness; who they want making medical care decisions if they can no longer make them; and how they want to be remembered after death.
Finding Meaning “Although it’s not clear that their understanding of death is the same as an adult’s would be in terms of consequences, when adolescents or young adults think about end-of-life, they do think about existential issues and their medical care, and they absolutely think about altruistic ways of living,” said Lori Wiener, PhD,
Branch, Center for Cancer Research at the National Cancer Institute; and lead author of the study. “The majority of study participants wanted to include information in the document that expressed their wish to either donate their cells or their bodies to science so that other people could benefit from their disease,” she continued. “Perhaps these patients, who have already been dealing with life-limiting illnesses, are even more open to giving back to others. It is a way of finding meaning in their life and in their experience.”

Young Survival Coalition Launches Post-treatment Navigator
n December, the Young Survival Coalition released What’s Next? A Young Woman’s Post-treatment Navigator, a survivorship guide to help young breast cancer survivors improve their quality of life after treatment ends. The Young Survival Coalition developed the guide after a 2010 survey it conducted found that 86% of its post-treatment population did not have a survivorship care plan in place following treatment. What’s Next contains information on what breast cancer survivors can expect after treatment ends, including long-term treatment side effects and fertility risks; sexuality and intimacy issues; how to make healthy lifestyle changes; electronic tools to manage medical expenses; and where to find help with financial assistance, as well as other survivorship resources. What’s Next also provides information on the importance of establishing a written follow-up care plan with the help of their oncologist and contains worksheets survivors can use to create a summary of their diagnosis and treatment. Copies of the Post-treatment Navigator are available at youngsurvival.org. n
young adults] feel they can’t have conversations about what they want or don’t want in their medical care and under what circumstances because their parents may feel that they are giving up hope. Parents may not want to have these conversations because they are afraid that if they start talking about ending treatment or end-of-life issues, their child will feel that the parent is giving up hope. The risk is that the child dies in emotional isolation at a time when both the child and the parent need to feel a sense of closeness and comfort each other,” said Dr. Wiener. Having a document in which adolescents and young adults with cancer can express their fears of death, worries over being forgotten, and desires to take part in their medical care decisions, provides an important communication tool for adolescents and young adults, their parents, and their medical team, hoping to en-
sure that these patients will not die emotionally alone, said Dr. Wiener. Future research will help determine whether this tool increases congruence between patients and families or their physician or improves patient outcomes. Allowing adolescents and young adults to participate in their end-oflife decisions also gives them back the sense of control and independence they were robbed of when they became ill. “People in this age group are at a critical developmental stage, where they are negotiating greater independence and autonomy, formulating their self-identity, and trying to define what their role is going to be in life. Living with a lifethreatening illness challenges every one of those developmental goals. Instead of working toward increasing their independence, they find themselves dependent on their parents, their medical team, and medicine,” said Dr. Wiener.
Getting the Conversation Started All medical discussions with seriously ill adolescents/young adults and their parents should begin before there is a medical emergency, and possibly even at the time of diagnosis, said Dr. Wiener. “It’s important to establish early on an open relationship with the patient and the family that is built on honesty. At the time of diagnosis, the oncologist might ask the patient a series of questions such as, What do you understand about your disease? How much information do you want us to share with you? Is it okay if I speak privately See Page 101 with your parents? Are there certain things you would like to speak to me about in private? Do you prefer that we provide you with written material or that we talk everything through?” said Dr. Wiener. “What we need to do is teach everybody on the medical team strategies to have conversations with patients and family members that do

A Day in the Life Never a Dull Moment: A Day in the Life of an Oncology Fellow By Bishoy Faltas, MD, as told to Ronald Piana Oncology fellows represent the future of cancer care, bringing the best and brightest young doctors into a rigorous training environment that molds their future career paths. Due to an impending workforce shortage in cancer care, the public health-care demands placed on today’s oncology fellows will be greater than ever. To give our readers insight into the life of an oncology fellow, The ASCO Post spoke with Bishoy Faltas, MD, who began his hematology/ oncology fellowship this past July at Weill Cornell Medical College in New York.
I
was born and reared in Egypt; I received my medical degree from the University of Asyut, located about 250 miles south of Cairo. After graduation, I pursued training in the United States because I was determined to become the best physician I could be. The high quality of medical training in the United States offered me that opportunity. I was also attracted to the idea of living in a “meritocracy” where advancement is based solely on the quality of one’s work. So I decided to come to the United States in 2006 and started my internal medicine residency in Rochester, New York. I was already leaning toward medical oncology during medical school, after losing my father to laryngeal cancer. During my residency, I found that I truly experienced fulfillment from taking care of patients with cancer, and this drew me more toward oncology.
Finding My Way: Guidance by Mentors During my residency, I was very fortunate to have wonderful mentors. Not only were they excellent role models, but they also helped me realize that oncology was my true calling. In particular, Dr. Paul L. Bernstein, my residency program director has left an indelible mark on my career. He taught me that the good physician is the one who is present at the bedside until the end. I remember for instance one time when he took me along with him to the funeral of one of our patients who had just passed away, to console the patient’s family. His high regard for continuous
scholarship truly inspired me. During my residency, we worked together to develop a rotation for medical residents to spend 2 weeks learning about the molecular basis of different diseases including cancer, while getting hands-on training in basic molecular techniques like polymerase chain reaction (PCR). It was an innovative course that helped me appreciate the biologic complexity of human disease, and it was a lot of fun! Dr. Bernstein encouraged me to follow my passion in oncology. So when the time came, I applied for oncology fellowships, interviewed at multiple places, and finally matched at Weill Cornell Medical College. One of the reasons I chose this program is the very strong mentorship
Last weekend, as I finished rounding on the solid tumor service, I received an emergency call to the ICU for a patient with acute leukemia, admitted with a white cell count of 200,000/mm3. He had severe metabolic acidosis and was intubated. We put in a nasogastric tube and administered hydroxyurea. We started leukapheresis to reduce the blast count. Unfortunately, despite our best efforts, the patient succumbed to the disease and by the end of the day had passed away. Days like this can be difficult, especially when you lose a patient. Learning how to cope with this is an essential part of becoming an oncologist. Oncology is an ever-changing field; one of the biggest challenges of the first year is to master that huge

to engage in research in pursuit of new and exciting ways to diagnose and treat cancer.
Choosing Oncology Now is a great time to go into oncology, There is growing concern about an impending workforce shortage in oncology. Cancer is poised to overtake cardiovascular death as the nation’s top killer. We need more oncologists, and I would encourage medical students and residents to consider a career in oncology. No doubt, an oncology career can be emotionally challenging. You deal with desperately sick patients, but helping these very vulnerable patients is very fulfilling. We are on the verge of seeing the fruits of the explosion of knowledge about the molecular basis of cancer. It is thrilling to be part of a forwardlooking medical field that is rapidly advancing its knowledge base and its ability to cure and palliate the world’s most dreaded disease. I can see it happening before my eyes, and I’m just at the beginning of my career! The prospect of being even a small part of this is very exciting.
Winding Down culture that starts at the highest levels of the department and trickles down to the level of fellows, residents, and medical students.
Exciting Times Fellowship is a very exciting time for me. I’m just 6 months into my 3-year combined hematology-oncology fellowship. The first year of fellowship is composed entirely of clinical rotations, purposely structured in a way that will allow for protected time for research later on. From the second year through the first half of the third year, the focus is on laboratory research, and the last 6 months of the fellowship is composed of electives. In the first year, my weekday schedule and duties are based largely on each specific clinical rotation, varying from day to day. The breadth and richness of the pathology I see is tremendous. On-call duties are infrequent, but the nature of problems one would encounter on the “front lines” is unpredictable.
body of knowledge while staying abreast of the new literature. Finding time to read could be challenging, but the numerous didactic occasions give us a “critical mass” of knowledge necessary to take care of patients.
Looking Ahead After completing my first year, I am very excited about the prospect of conducting laboratory research for the following 18 months. It is an opportunity to really get a deeper understanding of the biology of cancer. As I see patients everyday in the clinic, I see how cancer affects their lives. However, working with cancer cells up close and personal in the lab is quite different, bringing a new dimension to my understanding of cancer— a chance to “know thy enemy.” I am very grateful that my program offers the opportunity of “protected time” to pursue laboratory work. Although my career path is not set in stone, I’m fairly certain that I want to be an academic oncologist. I want
It takes passion and commitment to pursue a career in oncology. As rewarding as taking care of cancer is, our profession is very demanding, and one needs to use downtime to decompress and to refocus on one’s goals. For me, spending time with my family is the best way to unwind. Whenever I can, I try to spend time with my 3-year-old son George, and my wife Mary, who is studying to get into dental school. Although she is a full-time student in a very demanding program, she is always there to support me as I move into new and more challenging phases of my career. Burnout is a real phenomenon in oncology, so I’m fortunate to have a supportive family. When time permits, I take advantage of the numerous cultural attractions New York City has to offer. I have just started golf lessons, although I’m not sure how far that will go. Golf courses are hard to come by, but there is always a driving range nearby. n Disclosure: Dr. Faltas reported no potential conflicts of interest.

President Obama Signs High-mortality Cancer Bill into Law ust hours before the end of the 112th Congress, constitutional deadline for approval of a bill passed by that Congress, President Barack Obama signed into law the first legislation requiring comprehensive plans of research action for high-mortality cancers, with lung and pancreatic cancers given priority status for expedited attention.
Landmark Legislation This landmark legislation, included in the National Defense Authorization Act of 2013, requires the National Cancer Institute (NCI) to develop scientific frameworks for addressing cancers with survival rates of less than 50%, with first priority attention to lung and pancreatic cancers. The framework must be sent to Congress within 18 months. “Thank you Mr. President and thank you Congress for giving all of us in the lung cancer community and all those at risk for lung cancer the best possible present for the start of a new year,” said Lung Cancer Alliance President and CEO Laurie FentonAmbrose, whose national organization launched the legislative effort on lung cancer 6 years ago. “This is a new era for lung cancer. We are now out of the shadows,” Ms. Fenton-Ambrose said. “Our mission is to cut lung cancer mortality in half by the end of the decade,” she continued, “and we have added another tool in our arsenal to help make this goal a reality. This legislation, coupled with the validation of CT screening as a bigger potential life saver than any other cancer screening method, and with the Veterans Administration and the Department of Defense starting to screen high-risk veterans and military, could make this goal possible.”
islation was introduced to authorize a comprehensive plan of action. The primary sponsors included Senator Dianne Feinstein (D-CA), then Sen-
members Donna Christensen (DVI), Lois Capps (D-CA), Ed Whitfield (R-KY), and Frank LoBiondo (R-NJ). n

NCI Director Assesses Barriers to Faster Progress in Cancer Research By Ronald Piana
A
t a National Press Club media event in Washington, DC, on September 25, 2012, National Cancer Institute (NCI) Director Harold E. Varmus, MD, addressed a group of 75 reporters and officials. His discussion focused on impediments—biologic, economic, institutional, and cultural—to faster cancer research. In Dr. Varmus’s intro� duction, he noted that over the past
ever, our budget has remained flat for the past 5 years, and when inflation is factored in, NCI’s purchasing power has decreased by about 20% over the past 9 years,” Dr. Varmus explained. He continued, “Because of the dis� crepancy between the promise of sci� ence and adequate funding, the biomed� ical ecosystem is under unusual stress, putting the United States at risk of losing our global scientific leadership role.”
Three Categories of Good News
Harold E. Varmus, MD
40 years, NCI has spent about $90����� ���� bil� lion on research, yet cancer stubbornly remains a leading cause of death in the United States.
Vital Role of Government “The NCI has been in existence since 1937, so we’re celebrating the Institute’s 75th anniversary. It is the first of the socalled “categorical” institutes and cen� ters, which means that it is devoted to a specific disease or type of medical con� dition,” Dr. Varmus began, adding that there are now 27 institutes and centers. Dr. Varmus stressed that the NCI ex� emplifies the vital role government plays in bettering society, despite “some of the antigovernment rants from certain quar� ters.” He enumerated the institute’s mul� tiple contributions, commenting that along with the obvious scientific itiner� ary, the institute adds vibrancy to local and state economies. “The NCI’s yearly budget is just a hair more than $5 billion, which is spent mainly on grants that support thousands of individual scientists, scientific teams, centers, and training programs.

Dr. Varmus broke the NCI into its constituent parts, briefly explaining the goals of each sector. He then asked the rhetorical question: “How are we doing on the goal with which NCI was initially founded—conquering cancer?” In an� swer, he explicated the dizzying array of biologic complexities of cancer that
eloid leukemia. Moderate success has been achieved with targeted therapies in certain forms of lung cancer and my� eloma. Moreover, novel research in im� munotherapies shows promise in har� nessing our body’s immune system to fight cancer,” Dr. Varmus said. He also mentioned advances in surgical and ra� diotherapy techniques, along with im� provements over the past 2 decades in symptom management. He then discussed the third category of “good news”—advances in the basic understanding of the underlying proper� ties of the disease. “We now know unam� biguously that cancer is a disease of our genomes in which the genetic informa� tion is either changed or damaged. And we have new diagnostic categories that are defined by these genetic changes, which give rise to what we now refer to as precision medicine,” Dr. Varmus said.
We are at an unprecedented time in our ability to turn our understanding of cancer into major clinical advances. Yet, it is a sobering time because medical research is hindered by financial shortfalls. —Harold E. Varmus, MD
have confounded faster progress. Then he transitioned into the more realistic goal of controlling and managing cancer, which set the stage for what he called “three major categories of good news.” “First, we’ve seen a slow but steady decline in cancer mortality rates, roughly 1% to 2% per year over 2 decades, which is the best single measure of how we are doing in the battle against cancer. Sec� ond, this progress is not attributable to a single factor, but rather to a combined set of advances in early detection and preventive methods,” Dr. Varmus said. “In addition, we’ve improved sur� vival with a growing array of targeted therapies, the most dramatic of which is imatinib (Gleevec) for chronic my�
Scientific Dilemmas and Fiscal Constraints Despite the advances, Dr. Varmus said the decrease in age-adjusted mortal� ity in many cancers is unacceptably slow. “Moreover,” he continued, “several early detection methods have been overrated, most notably for prostate cancer. And although many cancers are behavior driven, we’ve had insufficient success in tobacco and weight control programs.” Dr. Varmus used a single gene to highlight the scientific dilemma. “We have had significant scientific leads that simply haven’t materialized—like the KRAS mutation, which accounts for about 30% of all cancers—yet we still haven’t developed targeted therapies to
address that clinical challenge.” After restating the obvious problem of deciphering the complex, heteroge� neous biology of cancer, Dr. Varmus affirmed that inadequate financing leads the list of impediments to cancer research. “Because of fiscal constraints, we currently only fund 14% of our grant applicants. Secondary fallout from this stringency is the chilling effect it has on young researchers, many of whom might shy away from the NCI because they feel the atmosphere is self-limiting,” Dr. Varmus said. “[Underfunding] generates an aver� sion-to-risk attitude by grant applicants and review panels, and consequently, they support safe science instead of rev� olutionary science,” he said.
Further Impediments “Researchers in the cancer commu� nity are also faced with an unprecedent� ed wave of data, and we currently don’t know how to create clinical correlations from the different sets of data; solving that informatics problem is another huge challenge,” he noted. Dr. Varmus also addressed a cultural impediment: “I have been a strong pro� ponent of making scientific materials and literature open and accessible so investigators can freely exchange their reagents and findings. Open science is one way to partially counteract the sti� fling effect of fiscal stringency, so it’s an important goal,” he stressed. “We are at an unprecedented time in our ability to turn our understanding of cancer into major clinical advances. Yet, it is a sobering time because medical re� search is hindered by financial shortfalls. Naturally, any cuts to our already tight budget would have devastating conse� quences to the NCI, an institute that contributes greatly to the public welfare. I remain an optimist, but we have to tem� per our goals,” Dr. Varmus concluded. n Disclosure: Dr. Varmus reported no potential conflicts of interest.

• The three most frequent non-hematologic adverse reactions were bruising, dizziness and headache • Patients with platelet counts <200 × 109/L at the start of therapy are more likely to develop thrombocytopenia during treatment. Thrombocytopenia was generally reversible and was usually managed by reducing the dose or temporarily withholding Jakafi. If clinically indicated, platelet transfusions may be administered • Patients developing anemia may require blood transfusions. Dose modifications of Jakafi for patients developing anemia may also be considered • Neutropenia (ANC <0.5 × 109/L) was generally reversible and was managed by temporarily withholding Jakafi • Patients should be assessed for the risk of developing serious bacterial, mycobacterial, fungal and viral infections. Active serious infections should have resolved before starting Jakafi. Physicians should carefully observe patients receiving Jakafi for signs and symptoms of infection (including herpes zoster)

and initiate appropriate treatment promptly • A dose modification is recommended when administering Jakafi with strong CYP3A4 inhibitors or in patients with renal or hepatic impairment [see Dosage and Administration]. Patients should be closely monitored and the dose titrated based on safety and efficacy • There are no adequate and well-controlled studies of Jakafi in pregnant women. 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.

As studied in COMFORT-I, a randomized, double-blind, placebo-controlled phase III study with 309 total patients (United States, Canada, Australia). The primary endpoint was the proportion of subjects achieving a ≥35% reduction in spleen volume from baseline to Week 24 as measured by magnetic resonance imaging (MRI) or computed tomography (CT) . A secondary endpoint was the proportion of subjects with a ≥50% reduction in TSS from baseline to Week 24 as measured by the daily patient diary, the modified Myelofibrosis Symptom Assessment Form (MFSAF v2.0).1,2
b Symptom
scores were captured by a daily patient diary recorded for 25 weeks. TSS encompasses debilitating symptoms of MF: 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.1,2

Pioneers in Oncology Physician-Scientist Judah Folkman, MD, Faced Years of Skepticism Before His Theory of Angiogenesis Was Proven

Judah Folkman, MD
T
hat Moses Judah Folkman would buck tradition, breaking his family’s long line of rabbinical succession and pursuing a career in science and medicine instead, was evident from the time he was a young child. Born in Cleveland on February 24, 1933, the first child of Rabbi Jerome and Bessie Folkman, young Judah eschewed more conventional children’s books in favor of biographies of Isaac Newton, Madame Marie Curie, and Louis Pasteur.
Early Life At age 7, Judah began accompanying his father on his Saturday hospital visits, where Rabbi Folkman comforted ailing members of his congregation and offered prayers. Meant to prepare Judah for his eventual rabbinic ordination, the visits convinced Judah that he wanted to offer patients more than spiritual solace alone. He wanted to help make them physically well. According to Dr. Folkman’s War: Angiogenesis and the Struggle to Defeat Cancer, by Robert Cooke,1 when Judah told his father of his intention to become a doctor instead of a rabbi, his father replied, “In that case, you can be a rabbi-like doctor.” By the time Judah was in high school, he was conducting experiments on small animals in his basement. For his entry in the Ohio Academy of Sciences competition, he devised a perfusion system powered by a small electric motor and a bicycle pump to keep the heart of a rat beating after being surgically removed. (Dr. Folkman would later jury-rig other devices, including a renal dialysis system
for a patient with acute renal failure, saving the patient’s life.) The experiment garnered Judah a prize in the competition and also put him on the path to Harvard Medical School at age 19, and a stint in the surgical laboratory of Dr. Robert Gross, then Surgeon-in-Chief at Children’s Hospital in Boston. There, he invented the first implantable heart pacemaker. After graduating magna cum laude from Harvard in 1957, Dr. Folkman became a surgical resident at Massachusetts General Hospital. In 1960 he married Paula Prial and soon they had two daughters, Marjorie and Laura. A third child, Kenneth, died in infancy from cystic fibrosis.
Birth of a New Field Soon after beginning his year as Senior Assistant Resident at Massachusetts General Hospital, Dr. Folkman was drafted into the navy and sent to do research at the National Naval Medical Center in Bethesda, Maryland. While
Hospital and continued his research efforts on tumor angiogenesis, although his hypothesis that malignant tumors must have a mechanism to induce the formation of blood vessels was met with growing skepticism—and even ridicule—from researchers steeped in methods that directly kill cancer cells. This skepticism affected his ability to obtain grants from the National Institutes of Health, his chances of being published in medical journals, and his capacity to attract young scientists to work in his lab. “I always viewed Dr. Folkman as an uplifting, inspiring, and genuinely enthusiastic person, but his first grants were rejected as being too visionary, and he fought an uphill battle to prove that a surgeon could transform science. He had to overcome the tunnel vision of that time,” said Steven Brem, MD, Co-Director, Penn Brain Tumor Center; Chief, Neurosurgical Oncology, Department of Neurosurgery at the Hospital of the University of Pennsyl-
Even as a student, I really had those moments of feeling that this man [Judah Folkman] was going to transform medicine. —Steven Brem, MD, former student of Dr. Folkman
conducting laboratory experiments on rabbits and mice implanted with cancer cells, Dr. Folkman noticed their tumors stopped growing when they were removed from the animals’ bodies but started growing again when the cells where implanted in another animal. The discovery led to his theory that tumors needed new blood vessels to provide them with the necessary oxygen and nutrients to keep them proliferating in a process known as “tumor angiogenesis.” During his time in Bethesda, Dr. Folkman also invented an implantable device for timed drug release (later developed as a means of administering the contraceptive levonorgestrel [Norplant]) and donated the patent to the World Population Council. In 1962, Dr. Folkman returned to Mass General to complete his surgical training and later became Chief Resident. Five years later, Dr. Folkman was named Surgeon-in-Chief of Children’s
vania; and a student of Dr. Folkman’s at Harvard Medical School. Dr. Folkman’s belief in angiogenesis as a cancer-cell proliferator was finally vindicated in the late 1980s when a scientist from the biotechnology company Genentech discovered vascular endothelial growth factor (VEGF), a protein that stimulates the formation of new blood vessels. In 2004, Genentech’s drug bevacizumab (Avastin), developed to block VEGF, was approved by the FDA for use in combination with standard chemotherapy drugs in the treatment of metastatic colon cancer, and later, for non–small cell lung cancer and renal cell carcinoma. Bevacizumab was also subsequently approved as a single agent in the treatment of glioblastoma as well as in macular degeneration.
Fulfilling a Father’s Wish A 1998 front-page article in The New York Times heralding Dr. Folk-
man’s laboratory work,2 including the discovery of endostatin and angiostatin as potential cancer fighters, ushered in an era of new hope about an end to cancer. The piece quoted Dr. James Watson, a Nobel laureate for the discovery of the structure of DNA, saying, “Judah is going to cure cancer in 2 years.” But Dr. Folkman refuted that claim in an issue of Scientific American later that year.3 “I don’t think angiogenesis inhibitors will be the cure for cancer,” he said. “But I do think that they will make cancer more survivable and controllable, especially in conjunction with radiation, chemotherapy, and other treatments.” Today, there are a dozen antiangiogenic drugs approved in oncology, including thalidomide (Thalomid), lenalidomide (Revlimid), sunitinib (Sutent), temsirolimus (Torisel), and everolimus (Afinitor), with more on the way. On January 14, 2008, Judah Folkman died of an apparent heart attack while waiting to change planes at a Denver airport on his way to a medical conference in Vancouver, British Columbia. “Dr. Folkman was like no other,” said Dr. Brem. “He was very inspiring and always full of enthusiasm. He could look 30 years or more into the future. His work preceded all of the translational research we have today in cancer and ophthalmology as well as other vascular diseases. He understood the importance of experiments, of logical thinking. Even as a student, I really had those moments of feeling that this man [ Judah Folkman] was going to transform medicine.” Dr. Folkman’s contributions to cancer research, and his career as a relentless scientist, caring physician, and gifted teacher, show beyond doubt that he lived up to his father’s admonition to become “a rabbi-like doctor.” n References 1.

Important Safety Information BOXED WARNING
Progressive multifocal leukoencephalopathy (PML): JC virus infection resulting in PML and death can occur in patients receiving ADCETRIS.
Contraindication:
Concomitant use of ADCETRIS and bleomycin is contraindicated due to pulmonary toxicity.
Warnings and Precautions:
• Peripheral neuropathy: ADCETRIS treatment causes a peripheral neuropathy that is predominantly sensory. Cases of peripheral motor neuropathy have also been reported. ADCETRIS-induced peripheral neuropathy is cumulative. Treating physicians should monitor patients for symptoms of neuropathy, such as hypoesthesia, hyperesthesia, paresthesia, discomfort, a burning sensation, neuropathic pain or weakness and institute dose modifications accordingly. • Infusion reactions: Infusion-related reactions, including anaphylaxis, have occurred with ADCETRIS. Monitor patients during infusion. If an infusion reaction occurs, the infusion should be interrupted and appropriate medical management instituted. If anaphylaxis occurs, the infusion should be immediately and permanently discontinued and appropriate medical management instituted. • Neutropenia: Monitor complete blood counts prior to each dose of ADCETRIS and consider more frequent monitoring for patients with Grade 3 or 4 neutropenia. If Grade 3 or 4 neutropenia develops, manage by dose delays, reductions or discontinuation. Prolonged (≥1 week) severe neutropenia can occur with ADCETRIS. • Tumor lysis syndrome: Patients with rapidly proliferating tumor and high tumor burden are at risk of tumor lysis syndrome and these patients should be monitored closely and appropriate measures taken.
• P rogressive multifocal leukoencephalopathy (PML): JC virus infection resulting in PML and death has been reported in ADCETRIS® (brentuximab vedotin)–treated patients. In addition to ADCETRIS therapy, other possible contributory factors include prior therapies and underlying disease that may cause immunosuppression. Consider the diagnosis of PML in any patient presenting with new-onset signs and symptoms of central nervous system abnormalities. Evaluation of PML includes, but is not limited to, consultation with a neurologist, brain MRI, and lumbar puncture or brain biopsy. Hold ADCETRIS if PML is suspected and discontinue ADCETRIS if PML is confirmed. • Stevens-Johnson syndrome: Stevens-Johnson syndrome has been reported with ADCETRIS. If Stevens-Johnson syndrome occurs, discontinue ADCETRIS and administer appropriate medical therapy. • U se in pregnancy: Fetal harm can occur. Pregnant women should be advised of the potential hazard to the fetus.
Adverse Reactions:
ADCETRIS was studied as monotherapy in 160 patients in two phase 2 trials. Across both trials, the most common adverse reactions (≥20%), regardless of causality, were neutropenia, peripheral sensory neuropathy, fatigue, nausea, anemia, upper respiratory tract infection, diarrhea, pyrexia, rash, thrombocytopenia, cough and vomiting.
Drug Interactions:
Patients who are receiving strong CYP3A4 inhibitors concomitantly with ADCETRIS should be closely monitored for adverse reactions.

Brief Summary of Prescribing Information (see Package Insert for full Prescribing Information)
WARNING: PROGRESSIVE MULTIFOCAL LEUKOENCEPHALOPATHY (PML) JC virus infection resulting in PML and death can occur in patients receiving ADCETRIS. Indications and usage These indications are based on response rate. There are no data available demonstrating improvement in patient reported outcomes or survival with ADCETRIS. ADCETRIS® (brentuximab vedotin) is indicated for treatment of patients with Hodgkin lymphoma (HL) after failure of autologous stem cell transplant (ASCT) or after failure of at least two prior multi-agent chemotherapy regimens in patients who are not ASCT candidates. ADCETRIS is indicated for treatment of patients with systemic anaplastic large cell lymphoma (sALCL) after failure of at least one prior multi-agent chemotherapy regimen.
Contraindications Pulmonary toxicity: Concomitant use of ADCETRIS and bleomycin is contraindicated due to pulmonary toxicity. In a clinical trial that studied ADCETRIS with bleomycin as part of a combination regimen, the rate of non-infectious pulmonary toxicity was higher than the historical incidence reported with ABVD (adriamycin, bleomycin, vinblastine, dacarbazine). Patients typically reported cough and dyspnea. Interstitial infiltration and/or inflammation were observed on radiographs and computed tomographic imaging of the chest. Most patients responded to corticosteroids.
Warnings and precautions Peripheral neuropathy
ADCETRIS treatment causes a peripheral neuropathy that is predominantly sensory. Cases of peripheral motor neuropathy have also been reported. ADCETRIS-induced peripheral neuropathy is cumulative. In the HL and sALCL clinical trials, 54% of patients experienced any grade of neuropathy. Of these patients, 49% had complete resolution, 31% had partial improvement, and 20% had no improvement. Of the patients who reported neuropathy, 51% had residual neuropathy at the time of their last evaluation. Monitor patients for symptoms of neuropathy, such as hypoesthesia, hyperesthesia, paresthesia, discomfort, a burning sensation, neuropathic pain or weakness. Patients experiencing new or worsening peripheral neuropathy may require a delay, change in dose, or discontinuation of ADCETRIS.
Infusion reactions
Infusion-related reactions, including anaphylaxis, have occurred with ADCETRIS. Monitor patients during infusion. If anaphylaxis occurs, immediately and permanently discontinue administration of ADCETRIS and administer appropriate medical therapy. If an infusion-related reaction occurs, the infusion should be interrupted and appropriate medical management instituted. Patients who have experienced a prior infusion-related reaction should be premedicated for subsequent infusions. Premedication may include acetaminophen, an antihistamine and a corticosteroid.
Neutropenia
Complete blood counts should be monitored prior to each dose of ADCETRIS and more frequent monitoring should be considered for patients with Grade 3 or 4 neutropenia. Prolonged (≥1 week) severe neutropenia can occur with ADCETRIS. If Grade 3 or 4 neutropenia develops, manage by dose delays, reductions, or discontinuations.
Tumor lysis syndrome
Tumor lysis syndrome may occur. Patients with rapidly proliferating tumor and high tumor burden may be at increased risk of tumor lysis syndrome. Monitor closely and take appropriate measures.
Progressive multifocal leukoencephalopathy
JC virus infection resulting in PML and death has been reported in ADCETRIS-treated patients. In addition to ADCETRIS therapy, other possible contributory factors include prior therapies and underlying disease that may cause immunosuppression. Consider the diagnosis of PML in any patient presenting with new-onset signs and symptoms of central nervous system abnormalities. Evaluation of PML includes, but is not limited to, consultation with a neurologist, brain MRI, and lumbar puncture or brain biopsy. Hold ADCETRIS dosing for any suspected case of PML and discontinue ADCETRIS dosing if a diagnosis of PML is confirmed.
Stevens-Johnson syndrome
ADCETRIS® (brentuximab vedotin) was studied in 58 patients with sALCL in a single arm clinical trial in which the recommended starting dose and schedule was 1.8 mg/kg intravenously every 3 weeks. Median duration of treatment was 24 weeks (range, 3 to 56 weeks). The most common adverse reactions (≥20%), regardless of causality, were neutropenia, anemia, peripheral sensory neuropathy, fatigue, nausea, pyrexia, rash, diarrhea, and pain. The most common serious adverse reactions experienced by patients with sALCL were septic shock (3%), supraventricular arrhythmia (3%), pain in extremity (3%), and urinary tract infection (3%).
Drug interactions In vitro data indicate that monomethyl auristatin E (MMAE) is a substrate and an inhibitor of CYP3A4/5.
Effect of other drugs on ADCETRIS
CYP3A4 Inhibitors/Inducers: MMAE is primarily metabolized by CYP3A. Co-administration of ADCETRIS with ketoconazole, a potent CYP3A4 inhibitor, increased exposure to MMAE by approximately 34%. Patients who are receiving strong CYP3A4 inhibitors concomitantly with ADCETRIS should be closely monitored for adverse reactions. Co-administration of ADCETRIS with rifampin, a potent CYP3A4 inducer, reduced exposure to MMAE by approximately 46%.
Effect of ADCETRIS on other drugs
Co-administration of ADCETRIS did not affect exposure to midazolam, a CYP3A4 substrate. MMAE does not inhibit other CYP enzymes at relevant clinical concentrations. ADCETRIS is not expected to alter the exposure to drugs that are metabolized by CYP3A4 enzymes.
Use in specific populations Pregnancy
Pregnancy Category D. There are no adequate and well-controlled studies with ADCETRIS in pregnant women. However, based on its mechanism of action and findings in animals, ADCETRIS can cause fetal harm when administered to a pregnant woman. Brentuximab vedotin caused embryo-fetal toxicities in animals at maternal exposures that were similar to human exposures at the recommended doses for patients with HL and sALCL. 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. In an embryo-fetal developmental study, pregnant rats received 2 intravenous doses of 0.3, 1, 3, or 10 mg/kg brentuximab vedotin during the period of organogenesis (once each on Pregnancy Days 6 and 13). Drug-induced embryo-fetal toxicities were seen mainly in animals treated with 3 and 10 mg/kg of the drug and included increased early resorption (≥99%), post-implantation loss (≥99%), decreased numbers of live fetuses, and external malformations (i.e., umbilical hernias and malrotated hindlimbs). Systemic exposure in animals at the brentuximab vedotin dose of 3 mg/kg is approximately the same exposure in patients with HL or sALCL who received the recommended dose of 1.8 mg/kg every three weeks.
Nursing mothers
It is not known whether brentuximab vedotin 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 ADCETRIS 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 effectiveness of ADCETRIS have not been established in the pediatric population. Clinical trials of ADCETRIS included only 9 pediatric patients and this number is not sufficient to determine whether they respond differently than adult patients.
Geriatric use
Clinical trials of ADCETRIS did not include sufficient numbers of patients aged 65 and over to determine whether they respond differently from younger patients. Safety and efficacy have not been established.
Renal impairment
The kidney is a route of excretion for MMAE. The influence of renal impairment on the pharmacokinetics of MMAE has not been determined.
Hepatic impairment
The liver is a route of clearance for MMAE. The influence of hepatic impairment on the pharmacokinetics of MMAE has not been determined.
Overdosage There is no known antidote for overdosage of ADCETRIS. In case of overdosage, the patient should be closely monitored for adverse reactions, particularly neutropenia, and supportive treatment should be administered.
Stevens-Johnson syndrome has been reported with ADCETRIS. If Stevens-Johnson syndrome occurs, discontinue ADCETRIS and administer appropriate medical therapy.
Dosage and administration
Use in pregnancy
The recommended dose is 1.8 mg/kg administered only as an intravenous infusion over 30 minutes every 3 weeks. The dose for patients weighing greater than 100 kg should be calculated based on a weight of 100 kg. Do not administer as an intravenous push or bolus. Continue treatment until a maximum of 16 cycles, disease progression or unacceptable toxicity.
There are no adequate and well-controlled studies of ADCETRIS in pregnant women. However, based on its mechanism of action and findings in animals, ADCETRIS can cause fetal harm when administered to a pregnant woman. Brentuximab vedotin caused embryo-fetal toxicities, including significantly decreased embryo viability and fetal malformations, in animals at maternal exposures that were similar to human exposures at the recommended doses for patients with HL and sALCL. If this drug is used during pregnancy, or if the patient becomes pregnant while receiving the drug, the patient should be apprised of the potential hazard to the fetus.
Adverse reactions ADCETRIS was studied as monotherapy in 160 patients in two phase 2 trials. Across both trials, the most common adverse reactions (≥10%), regardless of causality, were neutropenia, anemia, thrombocytopenia, lymphadenopathy, peripheral sensory neuropathy, peripheral motor neuropathy, headache, dizziness, fatigue, pyrexia, chills, pain, edema peripheral, upper respiratory tract infection, nausea, diarrhea, abdominal pain, vomiting, constipation, rash, pruritus, alopecia, night sweats, dry skin, cough, dyspnea, oropharyngeal pain, arthralgia, myalgia, back pain, pain in extremity, muscle spasms, insomnia, anxiety, decreased appetite and weight decreased. ADCETRIS was studied in 102 patients with HL in a single arm clinical trial in which the recommended starting dose and schedule was 1.8 mg/kg intravenously every 3 weeks. Median duration of treatment was 27 weeks (range, 3 to 56 weeks). The most common adverse reactions (≥20%), regardless of causality, were neutropenia, peripheral sensory neuropathy, fatigue, upper respiratory tract infection, nausea, diarrhea, anemia, pyrexia, thrombocytopenia, rash, abdominal pain, cough, and vomiting. The most common serious adverse reactions experienced by patients with HL include peripheral motor neuropathy (4%), abdominal pain (3%), pulmonary embolism (2%), pneumonitis (2%), pneumothorax (2%), pyelonephritis (2%), and pyrexia (2%).

Dr. Menendez and Dr. Allison previously held leadership positions in orthopedic oncology at the Uni� versity of Southern California. Dr. Menendez served as Chief of the Metastatic Bone Clinic, the Mul� tidisciplinary Sarcoma Center and the Center for Orthopaedic Oncol� ogy. His research focuses largely on musculoskeletal tumors. Before joining Cedars-Sinai, Dr. Allison was Assistant Chief of the University of Southern California Center for Orthopaedic Oncology at the University of Southern Califor� nia Norris Cancer Hospital. He has expertise in musculoskeletal oncolo� gy, joint reconstruction, and anterior hip replacement. n
Dose modification
Peripheral Neuropathy: Peripheral neuropathy should be managed using a combination of dose delay and reduction to 1.2 mg/kg. For new or worsening Grade 2 or 3 neuropathy, dosing should be held until neuropathy improves to Grade 1 or baseline and then restarted at 1.2 mg/kg. For Grade 4 peripheral neuropathy, ADCETRIS should be discontinued. Neutropenia: Neutropenia should be managed by dose delays and reductions. The dose of ADCETRIS should be held for Grade 3 or 4 neutropenia until resolution to baseline or Grade 2 or lower. Growth factor support should be considered for subsequent cycles in patients who experience Grade 3 or 4 neutropenia. In patients with recurrent Grade 4 neutropenia despite the use of growth factors, discontinuation or dose reduction of ADCETRIS to 1.2 mg/kg may be considered.

The Rise of the Vintage Readers Book Club By Jimmie C. Holland, MD, Mindy Greenstein, PhD, and Christian J. Nelson, PhD

F
or the past few years, we have been running an Aging and Can� cer Group at Memorial Sloan-Ketter� ing Cancer Center, to help the fastest growing group of cancer survivors— ie, the elderly—cope with the double whammy of aging and cancer. In some ways, these are opposite problems: Cancer crystallizes the fear of dying, whereas aging often crystallizes the fear of growing older and more infirm as the years go by. One challenge both issues have in common, though, is the sense of isolation they can engender.
Search for Solutions We have tried different approaches to these issues, based on various psy� chological models, particularly the work of Erik and Joan Erikson on de� velopment throughout the life cycle. We convened two “expert panels” of elders to help us pilot our ideas. Not surprisingly, when talk of theories and models of development came up, eyes routinely glazed over. And so we learned to keep theory out of it and stick to everyday life experiences. Then an amazing thing happened, based not on theory, research, or any kind of science, but, instead, on

the love between a grandmother and granddaughter. My ( JH) grand� daughter and I decided to start a grandmother/granddaughter book club, to read and discuss the Harvard Classics during her gap year before college. We so enjoyed the exchange of ideas across the generations. But when college finally started and my
keeping in mind the age of our readers, we selected texts from antiquity to the modern era, starting with writings by Ben Franklin and Cicero’s essay, “On Old Age.” If those choices sound dry to you, they were anything but. Whereas the regular group meetings averaged two to four members, the book club meet� ings sometimes had close to a dozen attendees. We could barely squeeze into the same room. Discussions were the most animated since the inception of the group. Clearly, the book club touched something very visceral for its members, who ranged in age from their mid-60s to mid-90s.
Reasons for Success What was it about the Vintage

Clearly, the book club touched something very visceral for its members, who ranged in age from their mid-60s to mid-90s. young partner became too busy, she suggested I start a new book club for elders interested in tackling the great books of western civilization. Which is exactly what I did. The new group, which we integrated into the Aging and Cancer Group, was called the Vintage Readers Book Club. We devoted one meeting a month to discussing passages from the classics;
Readers Book Club that was so inspir� ing to its members? And why was it so much more popular than the Aging and Cancer Group from which it had sprung? We have some theories. One pos� sibility is a cohort effect. People of a certain age aren’t comfortable with talk� ing about themselves in a therapeutic situation—there’s a stigma to anything
associated with psychiatry. But they can talk about books. Ironically, in talking about books, the conversations regu� larly come back to ourselves—what we think of what the author wrote and how it relates to our own experiences, includ� ing but not limited to our experience of aging and/or dealing with cancer. Which brings us to another pos� sible reason. One of the ways we cope with aging and cancer is simply to live our lives the best we can, and set goals on which to focus. Having a concrete external goal—to discuss Ben Frank� lin’s ideas of what makes us happy, for example—sounds a lot more fun than just generally discussing our problems, even if both discussions end up leading us to the same place! Cicero’s essay on old age was illumi� nating in another way, too. His descrip� tion of ageism thousands of years ago could have popped out of today’s New York Times. And what better way to feel connected to the world than to feel con� nected across boundaries of time and culture. n For further information about the Vintage Readers Book Club, e-mail Dr. Holland at hollandj@mskcc.org.

Patient’s Corner Breast Cancer
I’m Not the Same Person I Was before Cancer
Cancer has changed me in every way: physically, emotionally, and financially. By Tracey Aiello, as told to Jo Cavallo
I
t’s not clear to me—and my doc� tors can’t say with any certainty— whether taking birth control pills for many years had anything to do with my getting breast cancer 3 years ago, at age 44. But the cancer growing in my left breast was diagnosed as stage I, estrogen receptor–positive. Although I never felt a lump in that breast, when I noticed that the nipple had inverted I knew something was terribly wrong. After the diagnosis, my oncologist recommended that I have a complete mastectomy, but the thought of los� ing my whole breast was too scary for me to contemplate, and I asked for a lumpectomy instead. After two lumpectomies failed to provide clear tissue margins, my only recourse was to go ahead with the mastectomy. Before I had the surgery, I under� went 3 months of combination che� motherapy—I can’t remember the drug regimen—plus 6 weeks of daily radiation therapy to reduce the size of the tumor. Unfortunately, the treat� ment not only failed to accomplish its goal, it left me so sick and anxious, I was sure it would kill me long before the cancer.
Burden of Cancer When I was first diagnosed, I thought this cannot be happening to me, I don’t have time to have cancer. I
just wanted to hurry up with the treat� ment and get back to work and to my life. Although my health-care team did a great job of preparing me for the
well-being overwhelmed me to the point of complete collapse, and I had to be hospitalized for depression. I’m still on antidepressants, but the
Although my health-care team did a great job of preparing me for the physical ramifications of treatment, they didn’t explain the devastating financial and mental health repercussions I might suffer. —Tracey Aiello
physical ramifications of treatment, they didn’t explain the devastating financial and mental health repercus� sions I might suffer in the aftermath of the disease. Because I couldn’t work during my treatments—my blood counts were so low I had to have two blood trans� fusions, and I was very weak and nau� seous—I lost my health insurance. I had to use my life savings to pay medi� cal bills and cover day-to-day living expenses. Although my prognosis once treatment was completed was good, the fear of a cancer recurrence cou� pled with anxiety over my financial
fear of a recurrence is with me all the time, although it has lessened over the years. Getting a cancer diagnosis and a treatment plan was just the first step on the road to my recovery. The piece I was missing in the beginning was how to cope with the mental an� guish I would suffer. I understand that when people hear they have can� cer, their first thought is, “Am I going to die?” and all the effort is placed on saving the person’s life. But patients need to have the whole picture of what could possibly happen to them right from the start. It’s not enough to have only half the story.
Rebuilding a Life after Cancer I wish my oncology team had given me educational material about breast cancer that included informa� tion on both the physical and mental aspects of what I could expect and where to find help. It wasn’t until after my surgery and recovery that I realized the depths of my sadness over the loss of my breast and how it is impacting my life even now. I’m a single mom, anwd the reality of my altered body has made dating very difficult. It’s not just my social life that’s been stalled. I’m so worried and nervous about a cancer recurrence and what it would mean to me finan� cially, I have a difficult time concen� trating on my work as a phlebotomy technician. I find myself obsessively checking and double-checking my lab work and questioning my abil� ity to perform even the most routine tasks—something I never did before my cancer diagnosis. Being in a breast cancer support group is helping me cope, and I am getting counseling, which is restoring my sense of optimism for the future. It’s difficult, but I am trying to be more positive, put my cancer behind me, and move on. n Tracey Aiello lives in Cranston, Rhode Island.

FOR A DIFFERENT PERSPECTIVE IN RENAL CELL CARCINOMA, DISCOVER…
ANOTHER SIDE OF RCC
In the United States, RCC is the 9th most common malignancy and accounts for 2% to 3% of all adult cancers.1,2 Incidence rates continue to rise; however, the reason for this increase is unknown. 2 The American Cancer Society estimates that there will be 64,770 new cases of RCC and 13,570 RCCrelated deaths in 2012. 3
Studies have demonstrated the importance of sustained drug levels; however, these levels can be compromised when toxicities lead to dose modifications, interruptions, or discontinuations. 5,8,9 In the Phase 3 trials of targeted agents, 30% to 40% of patients required dose modifications, and in the community setting this percentage may be higher.7 Treatment modifications require significant monitoring by healthcare professionals, and may potentially compromise treatment exposure and patients’ daily living. 5,8
Is good enough, enough? Today’s RCC patients are often active, with busy lifestyles and families. With a median age at diagnosis of only 64, quality of daily living on therapy is critical. 3 While the introduction of targeted therapy has improved the management of advanced disease and the outlook for patients, new challenges and existing unmet needs may compromise not only patients’ everyday life, but overall outcomes.4,5
Furthermore, patients themselves may choose not to adhere to their dosing regimen due to discomfort or dissatisfaction with the toxicity of therapy. 8 Other factors that may affect adherence include misinterpretation of physician instructions, polypharmacy syndrome and lifestyle distractions (e.g., demands of work and family, lack of support).10
Therapy for advanced RCC has evolved…
There may be opportunities to improve patient care
Each therapeutic class of agents is associated with distinct adverse events. Despite recent advances in treatment, side effects remain an important issue in patient management.6
Proactive monitoring, early detection, and prompt management of side effects are important for optimal patient management. Additionally, open communication between patients and healthcare professionals can be crucial to try to avoid premature treatment discontinuations or adverse impacts on patients’ everyday lives. 5,8
Research has shown that a substantial proportion of patients—both in clinical trials and everyday clinical practice—may not receive the full dose of their therapy due to adverse event management.7,8

Survival never gets old VELCADE® (bortezomib) delivered >13-month overall survival advantage in combination with MP* vs MP alone for previously untreated multiple myeloma (median 56.4 vs 43.1 months [HR=0.695; 95% CI, 0.57-0.85; p<0.05]; 60.1-month median follow-up†)
Approved for subcutaneous and IV administration‡ VELCADE® (bortezomib) Indication and Important Safety Information INDICATION
VELCADE (bortezomib) is indicated for the treatment of patients with multiple myeloma.
CONTRAINDICATIONS
VELCADE is contraindicated in patients with hypersensitivity (not including local reactions) to bortezomib, boron, or mannitol, including anaphylactic reactions. VELCADE is contraindicated for intrathecal administration.
WARNINGS, PRECAUTIONS, AND DRUG INTERACTIONS
Peripheral neuropathy: Manage with dose modification or discontinuation. Patients with preexisting severe neuropathy should be treated with VELCADE only after careful risk-benefit assessment. ▼ Hypotension: Use caution when treating patients taking antihypertensives, with a history of syncope, or with dehydration. ▼ Cardiac toxicity: Worsening of and development of cardiac failure have occurred. Closely monitor patients with existing heart disease or risk factors for heart disease. ▼ Pulmonary toxicity: Acute respiratory syndromes have occurred. Monitor closely for new or worsening symptoms. ▼ Posterior reversible encephalopathy syndrome: Consider MRI imaging for onset of visual or neurological symptoms; discontinue VELCADE if suspected. ▼ Gastrointestinal toxicity: Nausea, diarrhea, constipation, and vomiting may require use of antiemetic and antidiarrheal medications or fluid replacement. ▼ Thrombocytopenia or Neutropenia: Monitor complete blood counts regularly throughout treatment. ▼
Tumor lysis syndrome: Closely monitor patients with high tumor burden. ▼ Hepatic toxicity: Monitor hepatic enzymes during treatment. ▼ Embryo-fetal risk: Women should avoid becoming pregnant while being treated with VELCADE. Advise pregnant women of potential embryo-fetal harm. ▼ Closely monitor patients receiving VELCADE in combination with strong CYP3A4 inhibitors. Avoid concomitant use of strong CYP3A4 inducers. ▼
ADVERSE REACTIONS
Most commonly reported adverse reactions (incidence ≥20%) in clinical studies include nausea, diarrhea, thrombocytopenia, neutropenia, peripheral neuropathy, fatigue, neuralgia, anemia, leukopenia, constipation, vomiting, lymphopenia, rash, pyrexia, and anorexia. Please see Brief Summary for VELCADE on next page. *Melphalan+prednisone.
VISTA: a randomized, open-label, international phase 3 trial (N=682) evaluating the efficacy and safety of VELCADE administered intravenously in combination with MP vs MP in previously untreated multiple myeloma (MM). The primary endpoint was TTP. Secondary endpoints were CR, ORR, PFS, and overall survival. At a prespecified interim analysis (median follow-up 16.3 months), VELCADE+MP resulted in significantly superior results for TTP (median 20.7 months with VELCADE+MP vs 15.0 months with MP [p =0.000002]), PFS, overall survival, and ORR. Further enrollment was halted and patients receiving MP were offered VELCADE in addition. Updated analyses were performed. ‡ The reconstituted concentration for subcutaneous administration (2.5 mg/mL) is greater than the reconstituted concentration for IV administration (1 mg/mL). †

Charles Sawyers, MD
Brief Summary INDICATIONS: VELCADE® (bortezomib) for Injection is indicated for the treatment of patients with multiple myeloma. VELCADE for Injection is indicated for the treatment of patients with mantle cell lymphoma who have received at least 1 prior therapy. CONTRAINDICATIONS: VELCADE is contraindicated in patients with hypersensitivity (not including local reactions) to bortezomib, boron, or mannitol, including anaphylactic reactions. VELCADE is contraindicated for intrathecal administration. WARNINGS AND PRECAUTIONS: Peripheral Neuropathy: VELCADE treatment causes a peripheral neuropathy that is predominantly sensory; however, cases of severe sensory and motor peripheral neuropathy have been reported. Patients with pre-existing symptoms (numbness, pain, or a burning feeling in the feet or hands) and/or signs of peripheral neuropathy may experience worsening peripheral neuropathy (including ≥Grade 3) during treatment with VELCADE. Patients should be monitored for symptoms of neuropathy, such as a burning sensation, hyperesthesia, hypoesthesia, paresthesia, discomfort, neuropathic pain or weakness. In the Phase 3 relapsed multiple myeloma trial comparing VELCADE subcutaneous vs intravenous, the incidence of Grade ≥2 peripheral neuropathy events was 24% for subcutaneous and 39% for intravenous. Grade ≥3 peripheral neuropathy occurred in 6% of patients in the subcutaneous treatment group, compared with 15% in the intravenous treatment group. Starting VELCADE subcutaneously may be considered for patients with pre-existing or at high risk of peripheral neuropathy. Patients experiencing new or worsening peripheral neuropathy during VELCADE therapy may require a decrease in the dose and/or a less dose-intense schedule. In the VELCADE vs dexamethasone phase 3 relapsed multiple myeloma study, improvement in or resolution of peripheral neuropathy was reported in 48% of patients with ≥Grade 2 peripheral neuropathy following dose adjustment or interruption. Improvement in or resolution of peripheral neuropathy was reported in 73% of patients who discontinued due to Grade 2 neuropathy or who had ≥Grade 3 peripheral neuropathy in the phase 2 multiple myeloma studies. The long-term outcome of peripheral neuropathy has not been studied in mantle cell lymphoma. Hypotension: The incidence of hypotension (postural, orthostatic, and hypotension NOS) was 8%. These events are observed throughout therapy. Caution should be used when treating patients with a history of syncope, patients receiving medications known to be associated with hypotension, and patients who are dehydrated. Management of orthostatic/postural hypotension may include adjustment of antihypertensive medications, hydration, and administration of mineralocorticoids and/or sympathomimetics. Cardiac Toxicity: Acute development or exacerbation of congestive heart failure and new onset of decreased left ventricular ejection fraction have occurred during VELCADE therapy, including reports in patients with no risk factors for decreased left ventricular ejection fraction. Patients with risk factors for, or existing, heart disease should be closely monitored. In the relapsed multiple myeloma study of VELCADE vs dexamethasone, the incidence of any treatment-related cardiac disorder was 8% and 5% in the VELCADE and dexamethasone groups, respectively. The incidence of adverse reactions suggestive of heart failure (acute pulmonary edema, pulmonary edema, cardiac failure, congestive cardiac failure, cardiogenic shock) was ≤1% for each individual reaction in the VELCADE group. In the dexamethasone group, the incidence was ≤1% for cardiac failure and congestive cardiac failure; there were no reported reactions of acute pulmonary edema, pulmonary edema, or cardiogenic shock. There have been isolated cases of QT-interval prolongation in clinical studies; causality has not been established. Pulmonary Toxicity: Acute Respiratory Distress Syndrome (ARDS) and acute diffuse infiltrative pulmonary disease of unknown etiology, such as pneumonitis, interstitial pneumonia, and lung infiltration have occurred in patients receiving VELCADE. Some of these events have been fatal. In a clinical trial, the first two patients given high-dose cytarabine (2 g/m2 per day) by continuous infusion with daunorubicin and VELCADE for relapsed acute myelogenous leukemia died of ARDS early in the course of therapy. There have been reports of pulmonary hypertension associated with VELCADE administration in the absence of left heart failure or significant pulmonary disease. In the event of new or worsening cardiopulmonary symptoms, consider interrupting VELCADE until a prompt, comprehensive, diagnostic evaluation is conducted. Posterior Reversible Encephalopathy Syndrome (PRES): Posterior Reversible Encephalopathy Syndrome (PRES; formerly termed Reversible Posterior Leukoencephalopathy Syndrome (RPLS)) has occurred in patients receiving VELCADE. PRES is a rare, reversible, neurological disorder, which can present with seizure, hypertension, headache, lethargy, confusion, blindness, and other visual and neurological disturbances. Brain imaging, preferably MRI (Magnetic Resonance Imaging), is used to confirm the diagnosis. In patients developing PRES, discontinue VELCADE. The safety of reinitiating VELCADE therapy in patients previously experiencing PRES is not known. Gastrointestinal Toxicity: VELCADE treatment can cause nausea, diarrhea, constipation, and vomiting, sometimes requiring use of antiemetic and antidiarrheal medications. Ileus can occur. Fluid and electrolyte replacement should be administered to prevent dehydration. Interrupt VELCADE for severe symptoms. Thrombocytopenia/Neutropenia: VELCADE is associated with thrombocytopenia and neutropenia that follow a cyclical pattern, with nadirs occurring following the last dose of each cycle and typically recovering prior to initiation of the subsequent cycle. The cyclical pattern of platelet and neutrophil decreases and recovery remained consistent over the 8 cycles of twice-weekly dosing, and there was no evidence of cumulative thrombocytopenia or neutropenia. The mean platelet count nadir measured was approximately 40% of baseline. The severity of thrombocytopenia was related to pretreatment platelet count. In the relapsed multiple myeloma study of VELCADE vs dexamethasone, the incidence of bleeding (≥Grade 3) was 2% on the VELCADE arm and <1% on the dexamethasone arm. Complete blood counts (CBC) should be monitored frequently during treatment with VELCADE. Platelet counts should be monitored prior to each dose of VELCADE. Patients experiencing thrombocytopenia may require change in the dose and schedule of VELCADE. Gastrointestinal and intracerebral hemorrhage has been reported in association with VELCADE. Transfusions may be considered. Tumor Lysis Syndrome: Tumor lysis syndrome has been reported with VELCADE therapy. Patients at risk of tumor lysis syndrome are those with high tumor burden prior to treatment. Monitor patients closely and take appropriate precautions. Hepatic Toxicity: Cases of acute liver failure have been reported in patients receiving multiple concomitant medications and with serious underlying medical conditions. Other reported hepatic reactions include hepatitis, increases in liver enzymes, and hyperbilirubinemia. Interrupt VELCADE therapy to assess reversibility. There is limited re-challenge information in these patients.

Korsmeyer Award from the American Society for Clinical Investigation in 2011 and the Lasker-De� Bakey Clinical Medical Research Award in 2009. He received MD degree from Johns Hopkins School of Medicine. n
Embryo-fetal: Pregnancy Category D. Women of reproductive potential should avoid becoming pregnant while being treated with VELCADE. Bortezomib administered to rabbits during organogenesis at a dose approximately 0.5 times the clinical dose of 1.3 mg/m2 based on body surface area caused post-implantation loss and a decreased number of live fetuses. ADVERSE EVENT DATA: Safety data from phase 2 and 3 studies of single-agent VELCADE 1.3 mg/m2/dose administered intravenously twice weekly for 2 weeks followed by a 10-day rest period in 1163 patients with previously-treated multiple myeloma (N=1008) and previously-treated mantle cell lymphoma (N=155) were integrated and tabulated. In these studies, the safety profile of VELCADE was similar in patients with multiple myeloma and mantle cell lymphoma. In the integrated analysis, the most commonly reported (≥10%) adverse reactions were nausea (49%), diarrhea NOS (46%), fatigue (41%), peripheral neuropathies NEC (38%), thrombocytopenia (32%), vomiting NOS (28%), constipation (25%), pyrexia (21%), anorexia (20%), anemia NOS (18%), headache NOS (15%), neutropenia (15%), rash NOS (13%), paresthesia (13%), dizziness (excl vertigo 11%), and weakness (11%). Eleven percent (11%) of patients experienced at least 1 episode of ≥Grade 4 toxicity, most commonly thrombocytopenia (4%) and neutropenia (2%). A total of 26% of patients experienced a serious adverse reaction during the studies. The most commonly reported serious adverse reactions included diarrhea, vomiting, and pyrexia (3% each), nausea, dehydration, and thrombocytopenia (2% each), and pneumonia, dyspnea, peripheral neuropathies NEC, and herpes zoster (1% each). In the phase 3 VELCADE+melphalan and prednisone study in previously untreated multiple myeloma, the safety profile of VELCADE administered intravenously in combination with melphalan/prednisone is consistent with the known safety profiles of both VELCADE and melphalan/prednisone. The most commonly reported adverse reactions in this study (VELCADE+melphalan/prednisone vs melphalan/prednisone) were thrombocytopenia (48% vs 42%), neutropenia (47% vs 42%), peripheral neuropathy (46% vs 1%), nausea (39% vs 21%), diarrhea (35% vs 6%), neuralgia (34% vs <1%), anemia (32% vs 46%), leukopenia (32% vs 28%), vomiting (26% vs 12%), fatigue (25% vs 14%), lymphopenia (23% vs 15%), constipation (23% vs 4%), anorexia (19% vs 6%), asthenia (16% vs 7%), pyrexia (16% vs 6%), paresthesia (12% vs 1%), herpes zoster (11% vs 3%), rash (11% vs 2%), abdominal pain upper (10% vs 6%), and insomnia (10% vs 6%). In the phase 3 VELCADE subcutaneous vs intravenous study in relapsed multiple myeloma, safety data were similar between the two treatment groups. The most commonly reported adverse reactions in this study were peripheral neuropathy NEC (37% vs 50%), thrombocytopenia (30% vs 34%), neutropenia (23% vs 27%), neuralgia (23% vs 23%), anemia (19% vs 23%), diarrhea (19% vs 28%), leukopenia (18% vs 20%), nausea (16% vs 14%), pyrexia (12% vs 8%), vomiting (9% vs 11%), asthenia (7% vs 16%), and fatigue (7% vs 15%). The incidence of serious adverse reactions was similar for the subcutaneous treatment group (20%) and the intravenous treatment group (19%). The most commonly reported SARs were pneumonia and pyrexia (2% each) in the subcutaneous treatment group and pneumonia, diarrhea, and peripheral sensory neuropathy (3% each) in the intravenous treatment group. DRUG INTERACTIONS: Bortezomib is a substrate of cytochrome P450 enzyme 3A4, 2C19 and 1A2. Co-administration of ketoconazole, a strong CYP3A4 inhibitor, increased the exposure of bortezomib by 35% in 12 patients. Monitor patients for signs of bortezomib toxicity and consider a bortezomib dose reduction if bortezomib must be given in combination with strong CYP3A4 inhibitors (eg, ketoconazole, ritonavir). Co-administration of omeprazole, a strong inhibitor of CYP2C19, had no effect on the exposure of bortezomib in 17 patients. Co-administration of rifampin, a strong CYP3A4 inducer, is expected to decrease the exposure of bortezomib by at least 45%. Because the drug interaction study (n=6) was not designed to exert the maximum effect of rifampin on bortezomib PK, decreases greater than 45% may occur. Efficacy may be reduced when VELCADE is used in combination with strong CYP3A4 inducers; therefore, concomitant use of strong CYP3A4 inducers is not recommended in patients receiving VELCADE. St. John’s wort (Hypericum perforatum) may decrease bortezomib exposure unpredictably and should be avoided. Co-administration of dexamethasone, a weak CYP3A4 inducer, had no effect on the exposure of bortezomib in 7 patients. Co-administration of melphalan-prednisone increased the exposure of bortezomib by 17% in 21 patients. However, this increase is unlikely to be clinically relevant. USE IN SPECIFIC POPULATIONS: Nursing Mothers: It is not known whether bortezomib 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 VELCADE, 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 effectiveness of VELCADE in children has not been established. Geriatric Use: No overall differences in safety or effectiveness were observed between patients ≥age 65 and younger patients receiving VELCADE; but greater sensitivity of some older individuals cannot be ruled out. Patients with Renal Impairment: The pharmacokinetics of VELCADE are not influenced by the degree of renal impairment. Therefore, dosing adjustments of VELCADE are not necessary for patients with renal insufficiency. Since dialysis may reduce VELCADE concentrations, VELCADE should be administered after the dialysis procedure. For information concerning dosing of melphalan in patients with renal impairment, see manufacturer’s prescribing information. Patients with Hepatic Impairment: The exposure of bortezomib is increased in patients with moderate and severe hepatic impairment. Starting dose should be reduced in those patients. Patients with Diabetes: During clinical trials, hypoglycemia and hyperglycemia were reported in diabetic patients receiving oral hypoglycemics. Patients on oral antidiabetic agents receiving VELCADE treatment may require close monitoring of their blood glucose levels and adjustment of the dose of their antidiabetic medication.

Expert’s Corner Issues in Oncology
ASCO CEO Discusses the Society’s Initiatives A Conversation with Allen S. Lichter, MD By Ronald Piana the oncology community. It’s chal� lenging, but the future is bright
Maturation of QOPI®
Allen S. Lichter, MD
C
reated in 1964,a the American Society of Clinical Oncology (ASCO) has become the world’s pre� eminent professional cancer organi� zation, with more than 30,000 mem� bers in the United States and abroad, unified by its founders’ “common concern for the patient with cancer.” The ASCO Post recently spoke with ASCO CEO Allen S. Lichter, MD, about what lies ahead as the Society approaches its 50th anniversary in 2014.
Aggressive Agenda Is ASCO well positioned to maintain its aggressive agenda in these challenging economic times? The short answer is yes. Our membership is still growing, and our meetings continue to be successful and well attended. Moreover, our list of journals and publications operate at a very high level. So our combined revenue streams help support the in� frastructure of ASCO and its many robust programs. Having said that, because many of the programs I mentioned are mature, the rate of growth begins to slow, as does any product or service that is long-lived. We are a great or� ganization made up of terrific vol� unteers and executive leaders who have more ideas than the resources to carry them out. Consequently, we spend a lot of time managing our pre� cious resources and exploring inter� esting new ways to bring revenue into ASCO, so that we can initiate more innovative programs and services for ASCO was founded in 1964 by a small group of physcians who aimed to create a society dedicated to issues unique to clinical oncology. a
Please give the readers an update on the Quality Oncology Practice Initiative (QOPI®). QOPI is nearing its 12th opera� tional year, and has been open to the full membership for 6-plus years now. The certification program for outpa� tient oncology practices has been operating for about 2 years; approxi� mately 150 practices have been certi� fied so far, with more coming down the pike. So the general maturation of QOPI has thus far been successful, and we have numerous ambitious plans on the drawing board for the program’s future. For instance, one of QOPI’s drawbacks is that it is a manual chart abstraction, which makes the entry process laborious. We are embarking on an exciting new
improve our clinical care. This is an ongoing project that will go through much iteration, but the end result will be worth the effort.
Electronic Medical Records Is the ASCO Health Information Technology Work Group leading this project? Yes. All of what I’ve just discussed about QOPI’s electronic future is predicated on the widespread dis� semination and interoperability of electronic medical records. ASCO has a vested interest in the health information technology field, and so far we’ve seen a positive response from those practices that have ad� opted electronic medical records. However, there are still many issues that need to be addressed—one, of course, is standardization. We have dozens and dozens of vendors, each with their own system and propri� etary methodology, which creates
It is incumbent on ASCO to make sure that we remain totally engaged, not only in furthering our commitment to advancing cancer research and quality cancer care, but also in efforts to support high-quality care that’s affordable to our patients, as we continue to address the rising costs of care. — Allen S. Lichter, MD
ruption. Also, many physicians com� plain that the use of electronic medi� cal records actually slows the delivery of care and takes attention away from the patient. Our Health Informa� tion Technology Work Group will address all of these issues. It is im� portant to note that although we’re experiencing the inevitable growing pains that accompany new technolo� gies, the wrinkles will eventually be smoothed, and the benefits will far outweigh the inconveniences.
Relationship with NCCN Is there an ongoing working relationship between ASCO and the National Comprehensive Cancer Network (NCCN)? First off, NCCN recently brought on a physician CEO, Robert W. Carlson, MD, a long-time and valued ASCO member (see page 8 for inter� view with Dr. Carlson). NCCN is in the process of finishing a new strate� gic plan, and ASCO officers have met with their leadership to discuss pos� sible collaborative efforts. We are both on the same side of advancing quality cancer care; NCCN adds a terrific contribution to that shared effort with, among other things, their broad and comprehen� sive practice guidelines. So we look forward to working with NCCN on a number of issues that are still in the planning stage.
Executive Leadership project that will evolve QOPI into a fully electronic program that would facilitate a seamless health informa� tion technology process. This would really cut down on labor, one of the main barriers to participation. We have a pilot program set for next year that will migrate QOPI from a manual paper program to an electronic-based system. The ul� timate step is to turn QOPI into a learning health-care model in which we are not only collecting data on process measurements—what the program currently does—but ob� taining information about what happens when certain clinical pro� cedures are done. We can then be� gin to correlate the processes with the outcomes, which will ultimately
confusion because it limits the abil� ity of physicians who are caring for the same patient to share and com� pare data. Using our breast cancer treatment summary as a model, ASCO is work� ing hard with oncologists and ven� dors on a data standardization initia� tive to see if we can define the fields in breast cancer that need to be pop� ulated. That type of electronic treat� ment summary could then be shared among physicians, and we could use the success of the breast project as a stepping-stone and broaden it out to other disease states. When we survey our members, the lack of interoperability is on top of the complaint list, followed closely by excessive costs and practice inter�
Tell us about ASCO’s recent appointment of Richard L. Schilsky, MD, as its new Chief Medical Officer. The ASCO board was very wise in bringing on another physician to an executive leadership role. Seventeen years ago, ASCO recruited its first physician executive, John R. Durant, MD, who recently passed away. Serving as Executive Vice President, Dr. Durant helped centralize the widening array of the Society’s agenda under one administrative roof, a major restructuring achievement. Since then, we have become a much bigger and more complex or� ganization, with deeper reach and interaction into multiple sectors of the health-care and policy system. So continued on page 92

the addition of Dr. Schilsky—a past ASCO President who has leadership experience running cancer centers and clinical trial groups—makes sense in that it enhances our ability to manage a controlled expansion of activities and services. Naturally, I
am very excited to have Dr. Schilsky on board.
Closing Thoughts Any last thought’s on ASCO’s future that you would like to share with the readers? The world of medicine is a challeng� ing, rapidly evolving environment. It
is incumbent on ASCO to make sure that we remain totally engaged, not only in furthering our commitment to advancing cancer research and quality cancer care, but also in efforts to sup� port high-quality care that’s affordable to our patients, as we continue to ad� dress the rising costs of care. The board met in March and creat�

ed a vision for oncology 20 to 25 years down the road. We are in the process of rolling out that vision so that we as a community can have serious dia� logue about the future and make sure we’re steering the ship in the right di� rection. n Disclosure: Dr. Lichter reported no potential conflicts of interest.

T
he use of dietary supplements by cancer patients has risen significantly over the past 2 decades despite insufficient evidence of safety and effectiveness. Finding re� liable sources of information about dietary supplements can be daunt� ing. Patients typically rely on fam� ily, friends, and the Internet, often receiving misleading information. The ASCO Post’s Integrative On� cology series is intended to facilitate the availability of evidence-based information on alternative and complementary therapies com� monly used by patients with cancer. We selected green tea for this issue because of its continued worldwide popularity as an antioxidant power� house, sought by many to prevent and treat cardiovascular disease and cancer. —Barrie R. Cassileth, PhD Integrative Oncology is compiled by Barrie R. Cassileth, MS, PhD, and Jyothirmai Gubili, MS, Memorial SloanKettering Cancer Center. The About Herbs website is managed by K. Simon Yeung, PharmD, Lac, Memorial Sloan-Kettering Cancer Center.
Overview
Green tea, a beverage consumed worldwide for its purported health bene�
fits, is derived from the leaves of the plant Camellia sinensis. Cultivated originally in East Asia, the plant is now grown in the Middle East and in some parts of Africa. The leaves used to prepare green tea are unfermented. Instead, they are steamed or heated immediately follow� ing harvest. This process preserves the integrity of polyphenols, compounds that act as antioxidants and contribute to the beneficial effects of green tea, by minimizing their oxidation. Green tea has a long history of use in traditional medicine as a stimulant, diuretic, for wound healing, to promote digestion, and to improve heart health. More recently, green tea and its extracts have been utilized to prevent and treat hyperlipidemia, hypertension, athero� sclerosis, and cancer. Green tea is avail� able as a dietary supplement in the form of capsules, extracts, and ointments for external application. However, despite wide consump� tion of green tea for cancer prevention, current data in support of that use are inconclusive. Green tea products also can interact with several prescription drugs, including anticancer agents. Pa� tients should consult their physicians before taking green tea in any form.

Adverse Effects
Hepatitis12-14; pruritic swelling and darkening of lower lip15; as well as thrombotic thrombocytopenic pur� pura have been reported following consumption of green tea.16 Animal studies indicate that when consumed during fasting, green tea ex� tract may increase the risk of toxicity.17
The Science
Green tea has been studied exten� sively over the past few decades. Clinical trials indicate that regular consumption of green tea may reduce the risk of hypertension1 and positively affect mood.2 It also enhances glucose tolerance in healthy individuals,3 but does not im� prove insulin sensitivity or glycemic con� trol in those with type II diabetes.4 Green tea may reduce mortality

been reported in humans.18 Bortezomib: EGCG and other polyphenols in green tea can inhibit the therapeutic effects of bortezo� mib (Velcade) and other boronic acid based proteasome inhibitors.19 Tamoxifen: EGCG was shown to increase the oral bioavailability of tamoxifen.20
OF NOTE Green tea is popular among pa� tients with cancer. Oncologists should be aware of its question� able anticancer effects and of its potential to interact with many prescription drugs, including che� motherapeutic agents. Verapamil: The bioavailability of verapamil increased significantly in the presence of EGCG, thought to be due to P-glycoprotein inhibition by EGCG.21 Irinotecan: A study found EGCG to inhibit transport of irinotecan and its metabolite SN-38 into biliary elimi� nation, resulting in their prolonged half-life, which can increase toxicity.22 UGT (uridine 5’-diphospho-glucuronosyltransferase) substrates: Green tea modulates UGT enzymes in vitro and can increase the side effects of drugs metabolized by them.23 Cytochrome P450 3A4 substrates: Green tea extract inhibits CY� P3A4 and can affect the intracellular
concentration of drugs metabolized by this enzyme.24 Acetaminophen: Green tea in� creased acetaminophen-induced hepatotoxicity in mice when adminis� tered following acetaminophen.25 n Disclosure: Drs. Cassileth and Yeung and Ms. Gubili reported no potential conflicts of interest.

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 Hypocalcemia
Osteonecrosis of the Jaw (ONJ)
• XGEVA® can cause severe hypocalcemia. 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 hypocalcemia has been reported. Advise patients to contact a healthcare professional for symptoms of hypocalcemia.
• 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.
• 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.
• 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.

Brief Summary: Consult package insert for complete Prescribing Information INDICATIONS AND USAGE: Bone Metastasis from Solid Tumors. Xgeva is indicated for the prevention of skeletal-related events in patients with bone metastases from solid tumors. Important Limitation of Use. Xgeva is not indicated for the prevention of skeletal-related events in patients with multiple myeloma (see Clinical Trials [14] in full Prescribing Information). DOSAGE AND ADMINISTRATION: Recommended Dosage. The recommended dose of Xgeva is 120 mg administered as a subcutaneous injection every 4 weeks in the upper arm, upper thigh, or abdomen. Administer calcium and vitamin D as necessary to treat or prevent hypocalcemia (see Warnings and Precautions). Preparation and Administration. Visually inspect Xgeva for particulate matter and discoloration prior to administration. Xgeva is a clear, colorless to pale yellow solution that may contain trace amounts of translucent to white proteinaceous particles. Do not use if the solution is discolored or cloudy or if the solution contains many particles or foreign particulate matter. Prior to administration, Xgeva may be removed from the refrigerator 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 Supplied/Storage and Handling). Use a 27-gauge needle to withdraw and inject the entire contents of the vial. Do not re-enter the vial. Discard vial after single-use or entry. CONTRAINDICATIONS: None. WARNINGS AND PRECAUTIONS: Hypocalcemia. Xgeva can cause severe hypocalcemia. 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 (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 (see Adverse Reactions). 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 immunogenicity. Using an electrochemiluminescent bridging immunoassay, less receive care by a dentist or an oral surgeon. In these patients, extensive dental than 1% (7/2758) of patients with osseous metastases treated with denosumab surgery to treat ONJ may exacerbate the condition. doses ranging from 30 â&#x20AC;&#x201C; 180 mg every 4 weeks or every 12 weeks for up to PREGNANCY: Xgeva can cause fetal harm when administered to a pregnant 3 years tested positive for binding antibodies.

In Trials 1, 2, and 3, patients were resulted in increased fetal loss, stillbirths, and postnatal mortality, along with 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 evidence of absent lymph nodes, abnormal bone growth and decreased every 4 weeks by intravenous (IV) infusion. Entry criteria included serum calcium neonatal growth. There are no adequate and well-controlled studies with Xgeva (corrected) from 8 to 11.5 mg/dL (2 to 2.9 mmol/L) and creatinine clearance in pregnant women. Women should be advised not to become pregnant when 30 mL/min or greater. Patients who had received IV bisphosphonates were taking Xgeva. If this drug is used during pregnancy, or if the patient becomes excluded, as were patients with prior history of ONJ or osteomyelitis of the jaw, an pregnant while taking this drug, the patient should be apprised of the potential active dental or jaw condition requiring oral surgery, non-healed dental/oral surgery, 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 beneďŹ ts in continuing or discontinuing treatment with Xgeva.
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.

Patients Treated for Colon Cancer Can Reduce Risk of Recurrence with Balanced Diet and Lower Carbohydrate Intake By Charlotte Bath
In the News focuses on media re� ports that your patients may have questions about at their next visit. This continuing column will pro� vide summaries of articles in the popular press that may prompt such questions, as well as com� ments from colleagues in the field.
P
atients who have received stan� dard treatment for colon cancer can take positive actions to reduce their risk of recurrence by following a balanced diet with fewer starchy foods that raise total gly� cemic load, accord� ing to Jeffrey A. Meyerhardt, MD, See Page 101 MPH, Associate Professor of Medicine at Dana-Far� ber Cancer Institute in Boston. Dr. Meyerhardt is lead author of a pro� spective, observational study exam�
Jeffrey A. Meyerhardt, MD, MPH
ining the influence of glycemic load, glycemic index, fructose, and carbo� hydrate intake among patients with stage III colon cancer. The study was embedded in a clinical trial (Cancer and Leukemia Group B [CALGB] 89803) compar� ing chemotherapy regimens for pa� tients who underwent complete sur� gical resection of the primary tumor, and had regional lymph node me� tastases but no evidence of distant metastases. Results of the dietary study were published in the Journal of the National Cancer Institute1 and reported in The New York Times2 and by other media outlets.
Earlier Investigation “This is our second study that has looked at diet in this cohort,” Dr. Meyerhardt told The ASCO Post.
“The first study3 was related to the Western pattern diet characterized by higher intake of red meats, pro� cessed meats, sugary desserts, re� fined grains.” Also involving patients with stage III colon cancer, that study found that those in the highest quin� tile of consumption of the Western pattern diet had a threefold increase in cancer recurrence and death com� pared to those in the lowest quintile. The second study was undertaken to “further understand which com� ponent of a Western pattern diet is associated with poorer outcomes and define the impact of dietary glycemic measures on colon cancer survival,” according to the study re� port. Results showed that higher di� etary glycemic load—a measure of the body’s plasma glucose response to foods—and total carbohydrate intake had a statistically significant association with an increased risk of recurrence and mortality. “It’s not that you have to totally avoid carbohydrates or totally avoid red meat,” Dr. Meyerhardt said, “but a healthy balanced diet is probably reasonable.” Dr. Meyerhardt noted that all patients in the study received what would be considered standard care for stage III colon cancer. “They all received surgery, and they all had ad� juvant chemotherapy.” He stressed that while following a healthy bal� anced diet is reasonable, “it is not a substitute” for treatment.
Physiologic Response to Carbohydrates “Both total carbohydrates and glycemic load—measures that re� flect your body’s response to foods high in those components—lead to higher insulin levels. And we know that insulin and insulin-like growth factors are drivers of colon cancer cell growth,” Dr. Meyerhardt said. “The physiological response to carbohydrates can be quantified by the glycemic index, a qualitative as� sessment of foods calculated as a per� centage of the body’s plasma glucose response to specific foods compared with the response induced by the same amount of carbohydrate from continued on page 101
Expect Questions from Patients
A
study finding that a diet high in total carbohydrates can increase the risk of cancer recurrence and mortality doesn’t mean that patients need to totally avoid carbohydrates, any more than previous findings about increased risk from a Western pattern diet means patients can’t eat any red meat. What the findings do mean, according to lead author Jeffrey Meyerhardt, MD, MPH, Associate Professor of Medicine at Dana-Farber Cancer Institute in Boston, is that “a healthy balanced diet is probably reasonable” for patients to reduce their risk of recurrence and improve their opportunities for survival. That diet should involve foods with a lower glycemic load, a measure of how much eating a specified serving size of a particular food raises blood glu� cose levels. For example, patients can be advised to choose fresh fruits like apples, oranges, and cantaloupes, which have much lower glycemic loads than do dried fruits like dates or raisins. Substituting whole grains for refined grains and choosing brown rather than white rice can also lower the glycemic load.
Complex Issues Dr. Meyerhardt said that when the study was first published in the Journal of the National Cancer Institute and then reported by the media, he was concerned that it might be misinterpreted as meaning that carbohydrates, and particularly sugar, were to be strictly avoided. “It is a little more complex than simply saying sugar makes cancer grow. It is the body’s response to a more starchy type of diet and the impact on glycemic load. It is not that you have to totally avoid sugar, or totally avoid carbohydrates; it has more to do with maintaining lower levels.” The patients participating in the study had stage������������������������� ������������������������ III colon cancer and re� gional lymph node metastases but no evidence of distant metastases, and all had complete resection and adjuvant chemotherapy. While following a healthy balanced diet is reasonable, “it is not a substitute” for treatment,” Dr. Meyerhardt stressed. “Another consideration for colon cancer survivors is that even if they don’t experience a cancer recurrence, they may have a risk for other diseases down the line, including heart disease and diabetes. These dietary measures have also been shown to be preventive against heart disease, diabetes, and other potential comorbidities,” Dr. Meyerhardt noted.
Prediagnosis Diet “Given that patients who consume high glycemic loads or carbohydrates after cancer diagnosis may have consumed a similar diet before diagnosis, we cannot exclude the possibility that individuals with these dietary expo� sures acquire tumors that are biologically more aggressive,” Dr. Meyerhardt and his colleagues stated in the published study. “When you ask patients questions about their diet and lifestyle and other host factors after diagnosis, you could also ask them what they did beforehand, but you would obviously have issues with recall bias. So we chose not to do that.” It is possible, he said, that patients reporting very high carbohydrate diets in the study also had a history of very high car� bohydrate diets before diagnosis, and that may have affected their risk of developing colorectal cancer and of having more aggressive cancer with a higher risk of recurrence. That distinction is relevant, Dr. Meyerhardt noted, because if risk of recurrence is related to the diet patients followed before first developing colorectal cancer, “it is not an actionable item.” Patients can’t retroactively change their diet before diagnosis. “So you hope that you can find recom� mendations for patients to improve their outcome once they already have the diagnosis,” he added. n

a standard carbohydrate source, usu� ally white bread or pure glucose,” the study report explained. In the study, 1,011 patients com� pleted food questionnaires during and after participating in the adju� vant chemotherapy trial. The ques� tionnaires included 131 food items, vitamins, mineral supplements, and open-ended questions for other sup� plements and foods not listed. The investigators calculated glycemic in� dex values and used them to calcu� late the mean dietary glycemic load “by multiplying the carbohydrate content for each food by its glycemic index value, multiplying that prod� uct by the servings of that food per day, and summing values for all food items reported.” Median follow-up after completion of the first ques� tionnaire was 7.3 years.
Overweight Patients “The primary endpoint of this analysis was disease-free survival. Higher dietary glycemic load was as� sociated with statistically significant worse disease-free, recurrence-free, and overall survival,” the investiga� tors reported. “Moreover, the delete� rious association of dietary glycemic load and total carbohydrate intake on survival was principally observed in patients who were overweight or obese.” Associations between glycemic load and survival differed accord� ing to body mass index. “Compared with patients with the lowest gly� cemic load quintile, those in the highest quintile experienced an ad� justed hazard ratio for disease-free survival of 1.79,” the authors report�
ed. But those with a body mass index ≥ 25 kg/m2 had an adjusted hazard ratio of 2.26. “We looked at a subgroup analy� sis of people who had a [body mass index] of 25 or less, which is consid�
Other Disease Stages Although the current study in� volved only stage III patients with regional lymph node metastases, Dr. Meyerhardt said, “we have looked at energy balance factors—for example,

ered either underweight or normal weight, or people whose [body mass index] was greater than 25, which is overweight and obese, and the as� sociation seemed to be strongest in those who were overweight and obese, which again is biologically plausible,” Dr. Meyerhardt said. Increasing evidence suggests that an energy imbalance between the calories consumed and expended impacts outcomes in colon cancer survival. “People who are physically inactive after diagnosis seem to have a higher risk of recurrence from their colon cancer,” according to pub� lished reports, Dr. Meyerhardt said. These reports consistently show “the importance of energy balance in co� lon cancer survivors and maintaining a healthy energy balance,” he added. The CALGB 89803 investigators concluded, “Although our observation� al study does not provide conclusive evidence for causality, these findings support the potential role of energy balance factors in colon cancer progres� sion and may offer opportunities to fur� ther improve patient survival.”

physical activity—in earlier stages of disease, either stage I or stage II, and we see a similar effect. We haven’t been able to study diet as much in stage I or stage II patients, but at least biologically, it would make sense. Patients with early disease develop a recurrence when they have micro� metastases that are not detected at the time of diagnosis. Assuming that these energy balance factors lead to a biologic response, perhaps insulin or insulin-like growth factors that drive the micrometastases to grow, that would provide the rationale for a similar response in early-stage dis� ease,” he said. “Whether these factors impact people with metastatic disease is a different question, because those are people who already have visible disease, and you are trying to slow the progression,” he continued. “We actually have a very large study for metastatic disease, also embedded in one of the cooperative groups trials.” That trial, CALGB/Southwestern Oncology Group (SWOG) 80405,
is a phase� ������������������������ III ������������������������ study comparing che� motherapy regimens for patients with untreated metastatic adeno� carcinoma of the colon or rectum. Patients complete a single question� naire early on, when their ability to maintain physical activity and follow a balanced diet is less likely to be im� pacted by disease progression.
Looking Ahead “We have already collected over 1,400 questionnaires from patients on that trial and will be able to look at those questions on diet and other lifestyle factors,” Dr. Meyerhardt said. The study has completed ac� crual but has not yet reached the primary endpoint of overall sur� vival. Results are expected later in 2013. Questionnaires have also been embedded into another adjuvant chemotherapy trial, CALGB 80702, comparing duration of chemother� apy and celecoxib (Celebrex) vs placebo. “In that trial, we expanded some questions related to energy balance and added questions about other comorbidities,” Dr. Meyer� hardt said.” n

an analysis of data from 1,077 women who were surveyed at a median of 3.7 years after BRCA screening, were pub� lished online first by the Archives of Internal Medicine. The women were asked about their subsequent risk-reducing

and screening interventions, including risk-reducing salpingo-oophorectomy, screening transvaginal ultrasonogra� phy, and screening serum cancer anti� gen 125 (CA-125). BRCA test results were categorized as positive (shown to carry known deleterious BRCA mutation) in 201 (18.7%) of these women, true-nega� tive (negative test result for a known deleterious family BRCA mutation) in 103 women (9.6%), and uninforma� tive negative (negative BRCA results without a known family mutation) or variant of undetermined significance (found to have a change in DNA that has unknown effects on BRCA protein function) in 773 women (71.8%). Women who tested positive as BRCA mutation carriers “were the most likely to receive aggressive in� terventions, with a 69.8% use of [riskreducing salpingo-oophorectomy] and a 28-fold higher odds of receiving [that procedure] compared with women with uninformative BRCA results,” the researchers reported. But many who were not identified as BRCA carriers also received aggressive interventions. “More than 70% of BRCA-tested women in this study—and in the United States—receive uninforma� tive results. In this understudied but important population, a substantial proportion underwent [salpingo-oo� phorectomy] (12.3%) and reported receiving ovarian cancer screening (30.2%) at least once in the preceding 3 years. Long-term ovarian cancer risk in women with uninformative BRCA results has not been carefully defined,” the researchers noted. “For most wom� en with uninformative BRCA results, salpingo-oophorectomy and ovarian cancer screening may not be appropri� ate, barring strong family histories of ovarian cancer.”

BREAST CANCER Analysis Suggests Screening Mammography Results in Substantial Overdiagnosis with Small Effect on Mortality An analysis of Surveillance, Epi� demiology, and End Results (SEER) data from 1976 through 2008 “sug� gests that whatever the mortality ben� efit, breast-cancer screening involved a substantial harm of excess detection of additional early-stage cancers that was not matched by a reduction in latestage cancers,” according to a report in The New England Journal of Medicine. “This imbalance indicates a consider� able amount of overdiagnosis involv� ing more than 1 million women in the past 3 decades—and, according to our best-guess estimate, more than 70,000 women in 2008 (accounting for 31% of all breast cancers diagnosed in women 40 years of age or older),” the authors wrote. The introduction of mammography has been associated with a large in� crease in early- stage breast cancer de� tected each year, from 112 to 234 can� cers per 100,000 women—an absolute increase of 122 cancers per 100,000 in the United States. There has also been a decrease in the cases of late-stage breast cancer—from 102 to 94 cases per 100,000. “With the assumption of a constant underlying disease burden, only 8 of the 122 additional early-stage cancers diagnosed were expected to progress to advanced disease. After excluding the transient excess incidence associat� ed with hormone-replacement therapy and adjusting for trends in the inci� dence of breast cancer among women
younger than 40 years of age, we esti� mated that breast cancer was overdi� agnosed (ie, tumors were detected on screening that would never have led to clinical symptoms) in 1.3 million U.S. women in the past 30 years,” the ana� lysts explained.
Serious Questions “Our study raises serious questions about the value of screening mam� mography,” the authors concluded. “It clarifies that the benefit of mortal� ity reduction is probably smaller, and the harm of overdiagnosis probably larger, than has been previously rec� ognized. And although no one can say with certainty which women have cancers that are overdiagnosed, there is certainty about what happens to them: They undergo surgery, radiation therapy, hormonal therapy for 5 years or more, chemotherapy, or (usually) a combination of these treatments for abnormalities that otherwise would not have caused illness. Proponents of screening should provide women with data from a randomized screening trial that reflects improvements in current therapy and includes strategies to miti� gate overdiagnosis in the intervention group. Women should recognize that our study does not answer the ques� tion ‘Should I be screened for breast cancer?’ However, they can rest as� sured that the question has more than one right answer.”

LUNG CANCER Volume-doubling Time May Help Distinguish Aggressive Cancer from Slow-growing Tumors Changes in the size of lung tumors over time, as measured by volumedoubling times on low-dose computed tomography, can be used to distin� guish aggressive lung cancer from slow-growing or indolent tumors and reduce overdiagnosis that could result in overtreatment and unnecessary morbidity. Results from a retrospec� tive estimation of volume-doubling times in a prospective low-dose com� puted tomography screening cohort also found that lung-cancer specific mortality was low among patients with slow-growing and indolent tumors. The study was published in the Annals of Internal Medicine. The nonrandomized single-center Continuous Observation of Smoking
Subjects (COSMOS) study recruited asymptomatic current or former heavy smokers (≥ 20 pack-years) aged 50 years and up who agreed to 5 consecu� tive years of low-dose computed to� mography. Of the 5,203 enrolled par� ticipants, 4,122 presented for all five annual scans. Of the 175 cases of primary lung cancer diagnosed, 55 were diagnosed at baseline (1.1% of the screened pop� ulation) and 120 were incident cancers detected during subsequent screen� ing rounds. Among those 120 cases, “the main focus of the study,” accord� ing to the authors, 19 (15.8%) were new (no nodule on previous scan) and fast-growing, with a median [volumedoubling time] of 52 days, and 101 (84.2%) had progressed from the year before, including 70 (58.3%) that were fast-growing and 31 (25.8%) that were slow-growing or indolent.
Major Results The median volume-doubling time was 223 for fast-growing and 545 days for slow-growing or indolent cancer. “The median [volume-doubling times] for adenocarcinomas (303 days) was significantly longer than that for squa� mous cell carcinomas (77 days) and cases of small cell cancer (70 days),” the researchers reported. “The main finding of our study is that [volume-doubling time] seems to be a plausible indicator of cancer ag� gressively in cases of incident cancer,” the authors wrote. Prognosis was high� ly favorable for cancers with a volumedoubling time of 200 or more days. “Another important finding of our study was that early diagnosis and early treatment, even of fast-growing cancer resulted in good long-term survival for our patients, most of whom had stage I disease at diagnosis, However, good
long-term survival must be balanced against the risk of invasive procedures for benign disease,” the authors added. In this study, 29 of the screened pa� tients who had surgical biopsy had be� nign disease. “Having identified potentially over� diagnosed lung cancer as slow-growing or indolent lesions, the problem of managing them remains,” the research� ers continued. In this study, all nod� ules suspicious for cancer were treated with surgical resection. The authors acknowledged, however, that “stan� dard resection (lobectomy with lymph node dissection) may be overtreat� ment for slow-growing or indolent lesions, most of which are minimally invasive adenocarcinomas,” and “a less-aggressive approach may be more appropriate.” The authors concluded that the vol� ume-doubling time analysis of cancers diagnosed after the initial screening “suggests that at least approximately 75% of detected cases were aggressive, downsizing the problem of overdiag� nosis. Among the 25% of slow-grow� ing or indolent cases, many are likely to have been overdiagnosed. To limit overtreatment in such cases, minimally invasive limited resection and nonsur� gical treatments should be investigated prospectively.” Veronesi G, et al: Ann Intern Med 157:776-784, 2012.

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.
Look inside for these important topics! • Preparation for the rash, itching, or dry skin that may come with cancer treatment • Care for the fingernails, and suggested products that will contribute to their health • Awareness of the risks for hair loss, and resources your patients may need • Suggested moisturizers and cosmetics that are appropriate for your patients’ use • Specific information for survivors
< 70 years treated with fludarabine compared to chlorambucil, but did not decrease among patients ≥ 70 years. “In contrast, the addition of rituximab to fludarabine decreased the risk of progression by 44% relative to fludara� bine alone (hazard ratio [HR] = 0.56; 95% confidence interval [CI] = 0.43– .001) and did not have a dif� 0.74; P < ����������������������������� ferential effect on [progression-free survival] by age group (P = .55),” the investigators wrote.
Study Implications “Among younger patients, the risk of death when treated with fludarabine decreased by 31% compared with the risk when treated with chlorambucil,” the researchers added. “Although not reaching statistical significance, the risk of death in older patients was es� timated to be 45% higher when treated with fludarabine vs chlorambucil.” Adding rituximab to fludarabine im� proved overall survival among all pa� tients, with the risk of death decreas� ing an estimated 35%. Alemtuzumab consolidation did not provide progres� sion-free or overall survival benefits. These and other results show that “chlorambucil is a reasonable chemo� therapeutic backbone on which to de� sign new combination regimens” for older adults with CLL,” the authors concluded. “With recent data regard� ing the combination of chlorambucil and rituximab in older patients, this combination is certainly a standard therapeutic option for older patients and may be an ideal platform on which to add new targeted agents to improve efficacy. To effectively treat older pa� tients with CLL, new therapies and combinations are needed that are ef� fective yet tolerable even for those patients with comorbid medical con� ditions or limited performance status.” Woyach JA, et al: J Clin Oncol.

pean School of Oncology, founded in 1982 by Umberto Veronesi, MD, con� vened the World Oncology Forum, tasked with evaluating the evidence on whether we are really winning the war on cancer. Eighty experts from five continents and 20 scientific jour� nalists from leading newspapers and magazines gathered in Lugano, Swit� zerland, on October 26–27, 2012, to try to reach a verdict. This was an un� usual gathering, where clinicians and researchers sat alongside specialists in cancer epidemiology, prevention, health policy (and policy implemen� tation and advocacy), while the sci� entific journalists were invited to play devil’s advocate. Intense discussions were kicked off by five keynote lecturers: Paolo Vineis, MD, MPH, FFPH, London; Douglas Hanahan, PhD, Lausanne, Switzerland; Michel Coleman, MD, MSc, MFPHM, London; Sir Rich� ard Peto, MD, FRS, Oxford, UK; and Felicia Knaul, MA, PhD, Bos� ton. The final session, which aimed to secure a consensus statement encapsulating key points from the preceding debates, was charismati� cally moderated by Richard Horton, association was not modified by sex, smoking status, or alcohol use.” Using data from the American Cancer Society Cancer Prevention Study II, the researchers identified 868 deaths due to oral/pharyngeal cancer occurred during 26 years of follow-up among 968,432 men and women who were cancer-free at enrollment. Those who drank four or more cups (237 mL) of caffeinated coffee had “a 49% lower risk of relative to no/occasional coffee intake (relative risk [RR] = 0.51, 95% CI = 0.40, 0.64),” the researchers reported. “The relative risk for decaf� feinated coffee intake was lower among those with daily intake of > 2 cups/day, but the estimate was of marginal statis� tical significance” (RR = 0.61, 95% CI = 0.37—1.01), the investigators add� ed. There was no association found for drinking tea. “Coffee, one of the most commonly consumed beverages worldwide, con� tains a variety of antioxidants, poly� phenols, and other biologically active compounds that may help to protect against development or progression of cancer,” the authors wrote. “The strong inverse association between fatal oral/

Mortality Trends The much lower cure rate in low-in� come countries means that, on a global scale, the fatality ratio is set to worsen. Poorer countries account for 85% of deaths from cervical cancer; the cure rate for breast cancer in Gambia and similar countries is below 15%; in the poorest 25 countries, pediatric cancers are fatal in 90% of cases, in contrast to the richest countries, where 90% of children now survive. This explains why at least 13 million cancer deaths are predicted for 2030, compared to about 7 million in 2008. In the developed world, by con� trast, while the annual rate of new cancers is steadily rising, mortality trends have been falling for some time. Better early detection and more effec� tive treatments are contributory fac� tors but play a smaller role than might have been hoped, as Prof. Peto demon� strated.

[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).]
WARNING: GASTROINTESTINAL PERFORATIONS, SURGERY AND WOUND HEALING COMPLICATIONS, and HEMORRHAGE
War on Cancer continued from page 105
drop in deaths from smoking-related cancers—from more than 240 per 100,000 in 1965 to only around 80 per 100,000 in 2010—that accounted for almost all the improvement in cancer mortality rates over that period.
Search for a Cure At the World Oncology Forum, there was a strong consensus that searching for ways to cure cancer re� mains a priority. However, current strategies, which rely heavily on pat� ents and short-term shareholders’ val� ue to develop new cancer therapies, are proving unsustainable; the costs of the new generation of drugs is get� ting out of all proportion to the added benefit. Some participants proposed raising the bar for new compounds to get access to the market, to halt the current trend toward performing ever-larger trials, chasing smaller and smaller benefits that might then be statistically, but not clinically, signifi� cant. So notwithstanding many partial successes and the exponential increase in our knowledge of cancer biology— and regardless of the terminology used—the statistics tell a clear story of an escalating crisis that current strate� gies are failing to adequately address.5 Following the 2011 United Nations Summit on Non-Communicable Dis� eases, governments of the world are already committed to cutting by 25% the number of preventable deaths by 2025. This would mean cutting at least 2 million deaths from cancer. To achieve this goal, and in line with the World Cancer Declaration,6 the World Oncology Forum is calling on govern� ments, policymakers, and all those who can help stop these unnecessary
deaths to commit to 10 key strategic points of action.
Future Publications The full World Oncology Forum statement will be published on Febru� ary 4th, World Cancer Day, in the International Herald Tribune under the heading “Stop Cancer Now,” and con� comitantly in Cancer World and to� gether with an editorial in The Lancet. The most important keynote lectures will also be published in The Lancet at a later date. The European School of Oncology may reconvene the World Oncology Forum in Milan in 2 years time, taking advantage of the city’s hosting of the 2015 World Exposi� tion, to evaluate progress in turning the tide against cancer. n Disclosure: Dr. Cavalli reported no potential conflicts of interest.

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).] 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. Limitation of Use: Avastin is not indicated for adjuvant treatment of colon cancer. [See Clinical Studies (14.2).] 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. 1.3 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).] 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).] 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 occurs at a higher incidence in Avastin‑treated patients compared to controls. The incidence of non‑gastrointestinal perforation was ≤ 0.3% in clinical studies. Most events occurred within the first 6 months of Avastin therapy. Discontinue Avastin in patients with fistula formation involving an internal organ. [See Dosage and Administration (2.4).] 5.5 Arterial Thromboembolic Events Serious, sometimes fatal, arterial thromboembolic events (ATE) including
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 4198 patients with CRC, non‑squamous NSCLC, glioblastoma, or mRCC trials including controlled (Studies 1, 2, 4, and 7) or uncontrolled, single arm (Study 5) 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 18‑88 years (median 60 years), 43.6% male and 83.8% white. The population included 1783 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.

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 5, 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).]
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)
IFN‑α plus placebo arm were fatigue (13% vs. 8%), asthenia (10% vs. 7%), proteinuria (7% vs. 0%), hypertension (6% vs. 1%; including hypertension and hypertensive crisis), and hemorrhage (3% vs. 0.3%; including epistaxis, small intestinal hemorrhage, aneurysm ruptured, gastric ulcer hemorrhage, gingival bleeding, haemoptysis, hemorrhage intracranial, large intestinal hemorrhage, respiratory tract hemorrhage, and traumatic hematoma). Grade 1–5 adverse events occurring at a higher incidence ( ≥ 5%) in patients receiving IFN‑α plus Avastin compared to the IFN‑α plus placebo arm are presented in Table 3. Table 3 NCI‑CTC Grades 1−5 Adverse Events in Study 7 (Occurring at Higher Incidence [≥ 5%] in IFN‑α + Avastin vs. IFN‑α + Placebo)
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.
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 signficantly 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.

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. 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 4. 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 5 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 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%). Metastatic Renal Cell Carcinoma (mRCC) All grade adverse events were collected in Study 7.

Adverse events were encoded using MedDRA, Version 10.1.
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 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
8.5 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 4, 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 7, 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. 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.

Proteinuria Grade 3–4 proteinuria ranged from 0.7 to 7.4% in Studies 1, 2, 4 and 7. The overall incidence of proteinuria (all grades) was only adequately assessed in Study 7, 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 7).

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 4, 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 5, 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%.
