Summary
The purpose of this study is to learn if BMS-512148 (Dapagliflozin) as part of a triple combination therapy can improve (decrease) hemoglobin A1c in patients with type 2 diabetes after 24 weeks of treatment compared to a 2 drug oral antidiabetic therapy. The safety of this treatment will also be studied.

    Open Label Treatment Period

    Note: Enrollment of subjects into the open-label (Stratum A) treatment period, beginning eee -16 of the study with HbA1c values at the lower bound (≥ 8.0% and ≤ 9.0%) and Enrollment of subjects into the open-label (Stratum B) eee -8, of the study with HbA1c values at the lower bound (≥ 7.5% and ≤ 8.5%) will be limited to approximately 50% of the total number of subjects randomized.

    • For subject in Stratum A:

    - At Week -10 and Week -2 a FPG qualification check will be performed. Subjects with a central laboratory FPG value meeting > 270 mg/dL will be scheduled for a follow-up visit (within 3 - 5 days) to obtain a second central laboratory FPG value. If the mean of the originally scheduled central laboratory FPG and the repeat central laboratory FPG value is > 270 mg/dL, the subject cannot be randomized and must be discontinued.

    - For subjects in Stratum B:

    - At Week -2 a FPG qualification check will be performed. Subjects with a central laboratory FPG value meeting > 270 mg/dL will be scheduled for a follow-up visit (within 3 - 5 days) to obtain a second central laboratory FPG value. If the mean of the originally scheduled central laboratory FPG and the repeat central laboratory FPG value is > 270 mg/dL, the subject cannot be randomized and must be discontinued

    Double Blind Treatment Period

    Inclusion criteria:

    • For Stratum A AND Stratum B:
