Primary Outcome Measures:

Adjusted Mean Change in Total Body Weight [ Time Frame: Baseline to Week 24 ]
To evaluate the effect of dapagliflozin 10 mg daily in combination with metformin compared to placebo in combination with metformin on total body weight after 24 weeks of oral administration of double-blind treatment.

Secondary Outcome Measures:

Adjusted Mean Change in Waist Circumference [ Time Frame: Baseline to Week 24 ]
To assess the effect of dapagliflozin 10 mg daily in combination with metformin compared to placebo in combination with metformin after 24 weeks of double-blind treatment on waist circumference.
Adjusted Mean Change in Body Fat Mass [ Time Frame: Baseline to Week 24 ]
To assess the effect of dapagliflozin 10 mg daily in combination with metformin compared to placebo in combination with metformin after 24 weeks of double-blind treatment on total body fat mass measured by dual energy X-ray absorptiometry.
Proportion of Participants With Body Weight Decrease ≥5% [ Time Frame: Baseline to Week 24 ]
To assess the effect of dapagliflozin 10 mg daily in combination with metformin compared to placebo in combination with metformin after 24 weeks of double-blind treatment on body weight decrease ≥5%. Least Squares Mean represents the percent of participants adjusted for body weight baseline value.

Other Outcome Measures:

Adjusted Percent Change in Bone Mineral Density (BMD) at Lumbar Spine (L1-4) [ Time Frame: Baseline to Week 102 ]
To assess the effect of dapagliflozin 10 mg daily in combination with metformin compared to placebo in combination with metformin after 102 weeks of double-blind treatment on Bone Mineral Density at lumbar spine (L1-4) as measured by Dual Energy X-ray Absorptiometry.
Adjusted Percent Change in Bone Mineral Density (BMD) at Femoral Neck [ Time Frame: Baseline to Week 102 ]
To assess the effect of dapagliflozin 10 mg daily in combination with metformin compared to placebo in combination with metformin after 102 weeks of double-blind treatment on Bone Mineral Density at femoral neck as measured by Dual Energy X-ray Absorptiometry.
Adjusted Percent Change in Bone Mineral Density (BMD) at Total Hip [ Time Frame: Baseline to Week 102 ]
To assess the effect of dapagliflozin 10 mg daily in combination with metformin compared to placebo in combination with metformin after 102 weeks of double-blind treatment on Bone Mineral Density at total hip as measured by Dual Energy X-ray Absorptiometry.
