Study summary

This study will look at the safety of substituting exenatide for insulin in patients with type 2 diabetes who are currently taking insulin and oral antidiabetic agent(s).

Read the detailed description

This is an exploratory, multicenter, open-label, 2-arm, parallel trial. Approximately 30 patients with type 2 diabetes, currently on a sulfonylurea, or meglitinide and/or metformin and insulin therapy, will be randomized to discontinue insulin and substitute it with exenatide or remain on their current diabetes therapy regimen. All patients will continue their current diet and exercise regimen during the study.
