Brief Summary

The objective of this study is to evaluate the efficacy on glycemic variability and safety of gemigliptin 50 mg orally administered once daily for 12 weeks compared with Dapagliflozin 10mg in patients with type 2 diabetes mellitus who have inadequate glycemic control on metformin alone or diabetes medication naïve patient
