Mitiglinide in Combination With Metformin vs. Metformin Alone in Patients With Type 2 Diabetes Mellitus

This is a randomized, double-blind, placebo-controlled, parallel group study designed to evaluate the efficacy and safety of mitiglinide in combination with metformin in patients with T2DM who are less than adequately controlled on metformin alone. Patients who are receiving metformin alone for T2DM will be randomized equally into one of three treatment groups.
