Details and patient eligibility

About

The primary purpose of this study is to compare the change from baseline in hemoglobin A1C achieved with dapagliflozin 10 mg in combination with metformin XR as compared with metformin XR monotherapy and compared with Dapagliflozin monotherapy, after 24 weeks of oral administration of double-blind treatment. The safety of treatment with dapagliflozin will also be assessed in this study
