Brief summary
This study is designed to compare the effects of twice-daily exenatide plus oral antidiabetic (OAD) agents and twice-daily placebo plus OAD with respect to glycemic control, as measured by hemoglobin A1c (HbA1c), in patients with type 2 diabetes who experience inadequate glycemic control with OAD alone.
Interventions
After a 2-week placebo lead-in period (twice daily, given subcutaneously) in addition to their current therapy regimen, subjects will administer 20 mcg of exenatide (2 units \[5 μg\] ), twice daily by subcutaneous injection, for the first 4 weeks of therapy, and then 40 μL of study drug (4 units \[10 μg\] of exenatide) twice daily by subcutaneous injection, for the remaining 12 weeks of therapy.
After a 2-week placebo lead-in period (twice daily, given subcutaneously) in addition to their current therapy regimen, subjects will administer placebo (in equivalent amounts to exenatide) for 16 weeks of therapy.
