Korean Study on Safety and Effectiveness of OAD Triple Therapy in Type 2 Diabetes

The study was designed as a multicenter, prospective, non-interventional, observational study in patients with type 2 diabetes mellitus who had inadequate glycemic control with conventional combination oral hypoglycemic agents including metformin.

Participants in this study will have type 2 diabetes mellitus with insufficient glycemic control on conventional combination therapy with a DPP-4i or SGLT2i oral hypoglycemic agent, including metformin, requiring the addition of one of the following: SGLT-2i, DPP-4i, or TZD.

The 3-drug combination therapy will be prescribed to subjects based on the medical judgment of the investigator based on the licensure of SGLT-2i, DPP-4i, or TZD(efficacy, dosing, precautions for use, etc.) in a real-world practice setting and all treatment and observation, including administration of medications and laboratory tests, will be based on the medical judgment of the investigator.
