E.2 Objective of the trial |
E.2.1 | Main objective of the trial | Main objective : In patients with type 2 diabetes mellitus with inadequate glycemic control on metformin at a dose of greater than or equal to 1500 mg/day: (1) After 24 weeks, to assess the effect of the addition of treatment with MK-0431 compared with placebo on HbA1c; (2) To assess the safety and the tolerability of MK-0431. | |
E.2.2 | Secondary objectives of the trial | Secondary objectives : After 24 weeks, to assess the effect of the addition of treatment with MK-0431 compared with placebo on: (1) fasting plasma glucose (FPG); (2) the plasma glucose profile after a standard meal challenge; (3) in a subset of patients undergoing more extensive blood sampling after a standard meal challenge: indices of insulin secretion derived from the C-peptide, insulin, and glucose profile. Over 104 weeks, to assess the effect of the addition of treatment of MK-0431 on: (4) HbA1c and FPG; (5) the durability of glycemic efficacy. | |
