Phase III Trial to Evaluate the Efficacy and Safety of Gemigliptin 50mg qd Added to Ongoing Glimepiride as Fix-dose Combination in Patients With Type 2 Diabetes

A Multicenter, Randomized, Placebo-controlled, Parallel Group, Double-blind, Phase III Trial to Evaluate the Efficacy and Safety of Gemigliptin 50mg qd Added to Ongoing Glimepiride as Fix-dose Combination in Patients With Type 2 Diabetes Inadequately Controlled on Glimepiride Alone

The study objective is to demonstrate the superiority and safety of the combination therapy (as a fix-dose combination) with Gemigliptin and Glimepiride, compared to the Glimepiride monotherapy in patients with type 2 diabetes.
