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.
