A Study to Compare the Glycemic Effects, Safety, and Tolerability of Exenatide Once Weekly to Those of Sitagliptin and Pioglitazone,in Subjects With Type 2 Diabetes Treated With Metformin (DURATION - 2)

March 19, 2015 updated by: AstraZeneca

A Randomized, Double-Blind, Parallel-Group, Multicenter Study to Compare the Glycemic Effects, Safety, and Tolerability of Exenatide Long-Acting Release(Once Weekly) to Those of Sitagliptin and a Thiazolidinedione in Subjects With Type 2 Diabetes Mellitus Treated With Metformin

This study will compare the benefits of exenatide once weekly treatment to those achieved by the approved antidiabetic therapies sitagliptin and pioglitazone in subjects whose type 2 diabetes is managed with metformin therapy alone. The safety and tolerability of the three treatment regimens will also be compared.

Secondary Outcome Measures

Secondary Outcome Measures
