Phase IIIb, randomized, multicenter, double-blind, prospective study to evaluate the efficacy and safety of a daily fixed-dose combination of glimepiride / vildagliptin / metformin in patients with type 2 diabetes with a history of dual treatment failure and combined or individual oral antidiabetics with SGLT2 / Metformin, Biguanide / Sulfonylurea, Sulfonylurea / iDPP4 or Biguanide / iDPP4. To evaluate the changes in the percentage of HbA1c at 3 and 6 months with regard to their baseline measurement.

To achieve glycemic control goals, a combination of medications with complementary mechanisms of action, with fasting and postprandial effects, may be required to achieve and maintain clinically acceptable glycemic control in some patients. A fixed combination of two or more therapeutic agents with complementary mechanisms of action makes it possible to optimize compliance and adherence to treatment among patients with T2D because it is administered once a day with the same efficacy of the separate components, but with fewer gastrointestinal effects. This is reflected in a reduction in HA1c and a lower evolution to long-term complications of T2D. Phase IIIb, randomized, multicenter, double-blind, prospective study to evaluate the efficacy and safety of a daily fixed-dose combination of glimepiride / vildagliptin / metformin in patients with type 2 diabetes with a history of dual treatment failure and combined or individual oral antidiabetics with SGLT2 / Metformin, Biguanide / Sulfonylurea, Sulfonylurea / iDPP4 or Biguanide / iDPP4.
