This is a 24-week, multicenter, randomized, double-blind, double-dummy, placebo-controlled, parallel group, phase 3 study designed to evaluate if the safety and efficacy of dapagliflozin 5 mg or 10 mg added to saxagliptin 5 mg plus metformin is superior to placebo added to saxagliptin 5 mg plus metformin in reducing hemoglobin A1c (HbA1c).
This study will be conducted in approximately 36 sites in Asian countries. Approximately 1004 subjects will be screened and 342 randomized. Prior to the screening, subjects of Stratum A should have a stable dose of metformin (≥1500 mg/day or a maximal tolerated dose) for at least 8 weeks. And subjects of Stratum B should have a stable dose of metformin (≥1500 mg/day or a maximal tolerated dose) AND a dipeptidyl peptidase-4 inhibitor at maximum approved dose for at least 8 weeks prior to the screening. Eligible subjects who complete the screening visit will enter the lead-in period, which includes open-label saxagliptin 5 mg and metformin treatment for 16 weeks in Stratum A or 8 weeks in Stratum B. At randomization visit, eligible subjects will be randomized into 1 of 3 treatment groups in a 1:1:1 ratio, receiving blinded dapagliflozin 5 mg, 10 mg or placebo plus metformin and saxagliptin 5 mg treatment for 24 weeks.
