Overview
Brief Summary
This randomized, open-label, parallel arm study will compare the safety, tolerability and effect on glycemic control of taspoglutide versus insulin glargine in insulin-naïve patients with type 2 diabetes mellitus inadequately controlled on merformin and sulfonylurea combination therapy. Patients will be randomized to receive either taspoglutide 10mg subcutaneously (sc) weekly, or taspoglutide 10mg sc weekly for 4 weeks followed by 20mg sc weekly, or insulin glargine at an initial dose of 10 international units sc daily. Metformin treatment will be continued in all patients throughout the study, whereas sulfonylurea will be discontinued before starting study treatment. Anticipated time on study treatment is 24 weeks, with an option to continue the assigned treatment for another 28 weeks. Target sample size is 500-600 patients.
