Type 2 Diabetes

Brief summary

The purpose of this clinical research study is to learn if initiating treatment with BMS-51248 (Dapagliflozin) in combination with metformin XR can improve diabetes control in patients with Type 2 Diabetes who do not receive any pharmacological treatment for diabetes, when compared to initial treatment with monotherapy dapagliflozin or metformin XR. The safety of this treatment will also be studied

MeasureTime frameDescription
Adjusted Mean Change From Baseline in Hemoglobin A1C (HbA1c) at Week 24 (Last Observation Carried Forward [LOCF])From Baseline to Week 24HbA1c was measured as percent of hemoglobin by a central laboratory. Data after rescue medication was excluded from this analysis. Baseline was defined as the last assessment prior to the start date and time of the first dose of the double-blind study medication. In cases where time of the first dose or time of the assessment was not available, baseline was defined as the last assessment on or prior to the date of the first dose of the double-blind study medication. HbA1c measurements were obtained during the qualification and lead-in periods and on Day 1 and Weeks 4, 8, 12, 16, 20, and 24 in the double- blind period.
