EDUCATIONAL OBJECTIVES • Individualize therapeutic goals for patients with T2DM based on disease severity, comorbidities, treatment-related risks, and psychosocial status • Discuss the clinical profiles of current and emerging fixed-dose combinations of antihyperglycemic medications • Intensify multidrug noninsulin regimens for various patient types to address poor glycemic control and other relevant clinical parameters • Engage patients in their antidiabetes management plans to motivate lifestyle changes and improve treatment adherence

Safety With Incretin-Based Agents Acute Pancreatitis

• Precautions1-5

• Recommendations1-5

– Cases have been reported – Unknown if pancreatitis history increases risk with DPP-4 inhibitors – Consider treatments other than GLP-1 RAs in patients with history of pancreatitis

– Ask about pancreatitis history – Educate patients about signs and symptoms of pancreatitis – Discontinue if pancreatitis symptoms occur – Report cases of pancreatitis to www.fda.gov/medwatch

Pancreatitis risk is 1.5- to 3-fold higher in individuals with diabetes6-8 1. See Drugs@FDA (http://www.accessdata.fda.gov/drugsatfda_docs/label/2011/021773s029s030lbl.pdf); 2.

Safety of Incretin Therapy 2014 FDA and EMA Analysis

• FDA and EMA conducted parallel, independent safety assessments of incretin-based drugs following postmarketing reports of pancreatitis or pancreatic cancer in treated individuals “Assertions of a causal association are not consistent with current data” “Product information and labeling reflect current understanding of risk” • Both agencies continue to investigate safety signals and data from ongoing trials EMA, European Medicines Association.

DPP-4 Inhibitors

Safety: Additional Considerations • Most common adverse effects1 – – – – –

Nasopharyngitis Headache Nausea Hypersensitivity Skin reactions

• FDA warnings – There is a risk for joint pain that can be severe and disabling2 – For saxagliptin and alogliptin, consider benefits vs risks in patients at risk for heart failure, and consider discontinuing if heart failure develops3 • SAVOR-TIMI 53 analysis showed that patients at highest risk of heart failure– related hospitalization had previous heart failure or chronic kidney disease4

• Reduce dose of alogliptin, saxagliptin, and sitagliptin in patients with moderate/severe renal impairment, or ESRD (CrCl ≤50 mL/min)1 CrCl, creatinine clearance. 1. Grunberger G.

GLP-1 RAs

Safety: Additional Considerations • Use caution in patients with renal impairment or renal transplantation, especially initiating or escalating doses1-6 – Hypovolemia due to nausea/vomiting may worsen renal function – Do not use exenatide formulations in patients with severe renal impairment (CrCl <30 mL/min) or ESRD

• All long-acting GLP-1 RAs should not be used in patients with MEN2 or a personal/family history of MTC2-5 – Counsel regarding MTC risk and symptoms of thyroid tumors – Report MTC to state cancer registry, regardless of treatment http://www.naaccr.org/Membership/MembershipDirectory.aspx MEN2, multiple endocrine neoplasia syndrome type 2; MTC, medullary thyroid carcinoma. 1.

SGLT-2 Inhibitors and Diabetic Ketoacidosis • Concerns

Potential Mechanisms

– 20 cases of DKA in T2DM reported to the FDA Adverse Events Reporting System (3/2013 to 6/2014) • Euglycemic DKA in T1DM (9 published cases) or T2DM (4 published cases) • Mostly women and/or linked to reduced insulin doses • Possible links to increased activity, recent illness, alcohol, and decreased food intake • Cases responded to IV rehydration + insulin

– Recent AACE statement • DKA occurs infrequently; risk-benefit ratio favors continued use of SGLT-2 inhibitors • Patients taking SGLT-2 inhibitors should avoid excess alcohol and very-low carbohydrate/ketogenic diets

– Consider lower doses in T1DM studies

SGLT-2 Inhibition Increases glucose renal clearance Decreases renal clearance of ketone bodies Endogenous and/or exogenous insulin levels reduced + Dehydration or increased activity level + Increased α-cell secretion of glucagon (mediated by SGLT-2) Increased lipolysis “Eudiabetic Ketoacidosis”

Jerry

Pharmacologic Treatment • Jerry and his PCP decide to start therapy with metformin BID and an SGLT-2 inhibitor – Jerry is educated on risks with both drugs – He is assessed for volume status – Both medications titrated up over next 2 weeks

• At a 3-month follow-up, Jerry’s A1c has fallen to 7.4% – Previous value, 8.7%

• Jerry often forgets which drugs he has taken each day – Frequently skips doses for T2DM or hypertension

• His weight is relatively unchanged – He reports continued bad eating habits during tax season

How can the PCP help improve Jerry’s adherence to lifestyle recommendations and his medications?

Simplify the Regimen Core Principles Adjust timing, frequency, amount, and dosage Match regimen to patient’s activities of daily living Recommend all medications are taken together Avoid medications with special requirements Avoid unnecessary side effects

Action • Prescribe once-daily medications • Dose to regular activities (eg, meals) • Consider combination formulations • Assess for drug-drug interactions and food absorption issues • Avoid medications that should not be taken with meals • Evaluate all potential side effects • May need to choose among side effects

Motivational interviewing is a collaborative conversation style for strengthening a person's own motivation and commitment to change by eliciting and exploring the persons own reasons for change Miller & Rollnick, 2013

21


Motivational Interviewing Stages of Change

1. Precontemplation Definition: Not yet considered or is unwilling or unable to change

6. Recurrence

2. Contemplation

Definition: Experienced a recurrence of the problems

Definition: Sees the possibility of change but is ambivalent and uncertain

5. Maintenance

3. Determination

Definition: Has achieved the goals and is working to maintain change

Definition: Committed to changing but still considering what to do

4. Action Definition: Taking steps toward change but hasn’t stabilized in the change process

Jerry

Key Points • Individualize treatment goals for patients with T2DM – Consider comorbidities – Address psychosocial factors – Take steps to reduce risk of hypoglycemia

• Ensure lifestyle modifications are the foundation of any treatment regimen for T2DM • Monitor multiple metabolic targets for comprehensive management and reduction of cardiovascular risk – A1c, lipids, BP

• When necessary, promptly intensify antihyperglycemic therapy – Consider early multidrug regimens that reflect the baseline degree of hyperglycemia and other clinical parameters – Minimize risks of hypoglycemia – Use combination formulations to address multiple pathologic mechanisms in T2DM and to simplify treatment regimens

Conclusions • Comprehensive T2DM management requires diligent monitoring of blood sugars, lipid profile, blood pressure, and body weight – Treatment is founded on lifestyle and behavioral modifications

• Hypoglycemic episodes are associated with serious adverse outcomes • Certain combinations of noninsulin agents can effectively reduce hyperglycemia with relatively low risks of hypoglycemia and potential for weight loss
