Primary

MeasureTime frame
Main Objective: • To demonstrate the efficacy of vildagliptin MR (12.5 mg bid or 25 mg bid) as add-on therapy to metformin in patients with T2DM by testing the hypothesis that the HbA1c reduction with vildagliptin MR added to metformin is superior to that of placebo added to metformin after 24 weeks of treatment. ;Secondary Objective: • To demonstrate the efficacy of vildagliptin MR (12.5 mg bid or 25 mg bid) as add-on therapy to metformin in patients with T2DM by testing the hypothesis that the HbA1c reduction with vildagliptin MR added to metformin is at least not inferior to that of sitagliptin 50 mg bid added to metformin after 24 weeks of treatment. • To demonstrate the efficacy of vildagliptin MR (12.5 mg bid or 25 mg bid) as add-on therapy to metformin in patients with T2DM by testing the hypothesis that the FPG reduction with vildagliptin MR added to metformin is superior to that of placebo added to metformin after 24 weeks of treatment. • To evaluate the safety and tolerability of vildagliptin MR (12.5 mg bid or 25 mg bid) compared to placebo and sitagliptin over 24 weeks of treatment as add-on therapy to metformin in patients with T2DM. For detailed secondary objectives, please refer to the full protocol.;Primary end point(s): The primary efficacy variable is change from baseline in HbA1c at Week 24 endpoint.
