Once-Weekly Efpeglenatide Dose-Range Effects on Glycemic Control and Body Weight in Patients With Type 2 Diabetes on Metformin or Drug Naive, Referenced to Liraglutide

摘要

OBJECTIVE To explore the efficacy, safety, and tolerability of once-weekly efpeglenatide, a long-acting glucagon-like peptide 1 receptor agonist (GLP-1 RA), in early type 2 diabetes (T2D) (drug naive or on metformin monotherapy). RESEARCH DESIGN AND METHODS EXCEED 203 was a 12-week, randomized, placebo-controlled, double-blind, parallel-group, dose-ranging study of efpeglenatide once weekly referenced to open-label liraglutide 1.8 mg (exploratory analysis). Participants, similar to 90% on metformin monotherapy, were randomized to one of five efpeglenatide doses (0.3, 1, 2, 3, or 4 mg q.w.; n = 181), placebo (n = 37), or liraglutide ( = 1 mg significantly reduced HbA(1c) versus placebo (placebo-adjusted least squares [LS] mean changes 0.6-1.2%, P = 1 mg than placebo achieved HbA(1c) <7% (61-72% vs. 24%, P < 0.05 for all), and greater reductions in body weight were observed with efpeglenatide 3 and 4 mg versus placebo (placebo-adjusted LS mean differences -1.4 and -2.0 kg, respectively, P < 0.05 for both). Rates of nausea and vomiting were consistent with other GLP-1 RAs and rapidly subsided after the initial 2 weeks. No neutralizing antibodies were detected with efpeglenatide. CONCLUSIONS Efpeglenatide once weekly led to significant reductions in HbA(1c) and weight, with a safety profile consistent with the GLP-1 RA class in patients with early T2D mostly on metformin monotherapy.
