Clinical Updates in Type 2 Diabetes by Integritas Communications

Clinical Updates in TYPE 2 DIABETES Evolving Roles of GLP-1 Receptor Agonists

Learning Objectives • Describe the major pathologic deficits underlying T2DM development with a focus on relationships with incretin hormone signaling • Individualize therapy for patients with T2DM based on disease severity, therapeutic goals, comorbidities, and treatment-related risks, including hypoglycemia • Select appropriate patients with T2DM for treatment with short- or long-acting GLP-1 RAs • Intensify antidiabetes regimens for various patient types to address poor fasting and/or postprandial glycemic control and other relevant clinical parameters • Educate patients on lifestyle changes, the clinical profiles of GLP-1 RAs, and treatment adherence

GLP-1 RAs = glucagon-like peptide-1 receptor agonists; T2DM = type 2 diabetes mellitus.

Shared Decision Making and Coordinated Care in T2DM Goals

Potential Benefits

• Establish a partnership based on exchange of information • Discuss treatment options • Match therapies with patient preferences • Prioritize actions required to fulfill clinical decisions

• Individualized goals and therapy • Improved treatment outcomes • Mitigated behavioral risks and psychosocial hurdles • Increased treatment adherence • Reduced inappropriate care and healthcare costs

Barriers • Time constraints • Patient health literacy • Lack of clinician accessibility and availability • Patient/provider power imbalance

Solutions • Interprofessional care • Patient decision aids

Alice Treatment Initiation and Follow-up • •

Prescribed metformin 500 mg twice daily – Titrated up to 1000 mg twice daily after 1 week At 1-month follow-up appointment – A1C, 7.9% • Previous value, 8.5% • Target value, ≤6.5% – FPG, 125 mg/dL • Previous value, 225 mg/dL – PPG, 219 mg/dL (2-hours postmeal) – No significant changes in any other clinical parameters

Clinician suggests adding a GLP-1 RA. Should the 2nd agent have been initiated with metformin? PPG = postprandial glucose.

• GLP-1 and GIP stimulate insulin release in response to food intake • Reduced incretin effect is an early sign of T2DM development • GLP-1 and GIP are rapidly degraded by DPP-4 – Incretin-based therapies include degradation-resistant GLP-1 RAs and inhibitors of DPP-4 N = 8 metabolically healthy control subjects.

Safe Prescribing With GLP-1 RAs Possible Thyroid and Endocrine Risk Contraindications1-5

Albiglutide Dulaglutide

Do not use if personal/ family history of MTC or presence of multiple endocrine neoplasia syndrome type 2

•

Exenatide Exenatide Liraglutide Twice Daily Once Weekly

Recommendations •

Counsel patients regarding MTC risk and symptoms of thyroid tumors

•

Value of routine calcitonin and/or ultrasound monitoring is uncertain; such monitoring may lead to unnecessary procedures

•

Patients with thyroid nodules or elevated serum calcitonin levels identified for other reasons should be sent to an endocrinologist

•

Report MTC to state cancer registry, regardless of treatment http://www.naaccr.org/Membership/MembershipDirectory.aspx

Recommendations for GLP-1 RA Use Possible Renal Impairment Risk Precautions

Renal issues1-5

•

Albiglutide

Use with caution

Dulaglutide

Use with caution

Exenatide Twice Daily

Use with caution Should not be used with severe renal impairment (CrCl <30 mL/min) or ESRD

Exenatide Once Weekly

Use with caution Should not be used with severe renal impairment (CrCl <30 mL/min) or ESRD

Liraglutide

Use with caution

Recommendations –

Use with caution in patients with renal impairment or renal transplantation, especially when initiating or escalating doses

–

Hypovolemia due to nausea/vomiting may worsen renal function

Alice Key Points • Individualize goals and treatment intensity for T2DM – Consider comorbidities – Address psychosocial factors – Take steps to reduce risk of hypoglycemia • Monitor multiple metabolic targets for comprehensive management and reduction of CV risk – A1C, lipids, BP • Consider appropriate roles of GLP-1 RAs – Clinically relevant reductions in A1C – Relatively low risks of hypoglycemia – Potential for weight loss and other CV benefits

PCE Action Plan  Routinely screen for T2DM with a frequency that reflects patient age, family history, and other risk factors  Ensure lifestyle modifications are the foundation of any treatment regimen for T2DM  Counsel patients about the risks, signs, and symptoms of pancreatitis before initiating treatment with a GLP-1 RA  Select GLP-1 RAs for T2DM based on the patient’s hyperglycemia profile and preferences  Recommend that patients eat smaller meals and more slowly when initiating treatment with a GLP-1 RA
