A 30-week, randomised, non-inferiority study compared a long-acting release formulation of exenatide 2 mg administered once weekly to 10 μg exenatide administered twice a day, in 295 patients with type 2 diabetes (haemoglobin A_1c [HbA_1c] 8·3% [SD 1·0], mean fasting plasma glucose 9 [SD 2] mmol/L, weight 102 [SD 20] kg, diabetes duration 6·7 [SD 5·0] years). The patients were naive to drug therapy, or on one or more oral antidiabetic agents. The primary endpoint was the change in HbA_1c at 30 weeks. This study is registered with ClinicalTrials.gov …
