A Study of Taspoglutide in Type 2 Diabetic Patients

This crossover study will assess the effect of 2 doses of Taspoglutide on first- and second-phase insulin secretion in patients with type 2 diabetes. Patients will receive a continuous subcutaneous infusion of a)the Immediate Release Formulation (IRF)of Taspoglutide 300 micrograms/day for 2 days followed by Taspoglutide 800 micrograms/day for 2 days or b)saline placebo for 2+2 days. After a washout period of 10-15 days, patients will be crossed-over for further treatment;those receiving Taspoglutide in period 1 will receive placebo in period 2, and vice versa. On days 2 and 4 of each period, insulin secretion patterns will be assessed. The anticipated time on study treatment is \<3 months, and the target sample size is \<100 individuals.
