Abstract
Background: Exenatide, an incretin mimetic for adjunctive treatment of type 2 diabetes (T2DM), reduced hemoglobin A1c (A1C) and weight in clinical trials. The objective of this study was to evaluate the effects of ≥ 3 years exenatide therapy on glycemic control, body weight, cardiometabolic markers, and safety.Methods: Patients from three placebo-controlled trials and their open-label extensions were enrolled into one open-ended, open-label clinical trial. Patients were randomized to twice daily (BID) placebo, 5 µg exenatide, or 10 µg exenatide for 30 weeks, followed by 5 µg exenatide BID for 4 weeks, then 10 µg exenatide BID for ≥3 years of exenatide exposure. Patients continued metformin and/or sulfonylureas.Results: 217 patients (64% male, age 58 ± 10 years, weight 99 ± 18 kg, BMI 34 ± 5 kg/m2, A1C 8.2 ± 1.0% [mean ± SD]) completed 3 years of exenatide exposure. Reductions in A1C from baseline to week 12 (−1.1 ± 0.1% [mean ± SEM]) were sustained to 3 years (−1.0 ± 0.1%; p < 0.0001), with 46% ac...
