Efficacy and Safety of CKD-501 Added to D150 Plus D745 25mg Therapy in Patients With Type 2 Diabetes

Efficacy and Safety of CKD-501 Added to D150 Plus D745 25mg Therapy in Patients With Type 2 Diabetes Inadequately Controlled With D150 Plus D745 25mg: Multi-center, Randomized, Double-blind, Parallel-group, Placebo Control, Therapeutic Confirmatory Study.

The purpose of this study is to prove that the group treated with CKD-501 in combination added that the reduction of glycated hemoglobin superior to placebo treated group added in combination.

The aim of this phase III study was to evaluate the efficacy and safety of additional combined CKD-501 administration for 24 weeks in patients with type 2 diabetes who were not adequately controlled for blood glucose by the combination of D150 and D745 25mg .

Furthermore, the extension study for additional 28 weeks is designed to confirm long term safety of actual drug as an oral hypoglycemic agent.
