- Change From Baseline in HbA1c at Week 24 for Double-blind Group [ Time Frame: Baseline to week 24 ]HbA1c was obtained at baseline and at Week 24. The model-adjusted change from baseline was calculated using mixed-effects repeated measures analysis.
- Change From Baseline in HbA1c at Week 24 for High Glycemic Group [ Time Frame: Baseline to week 24 ]The change in HbA1c from baseline at Week 24 in High Glycemic Group was calculated by subtracting the mean HbA1c at baseline from the mean HbA1c at Week 24
- Change From Baseline in Fasting Plasma Glucose (FPG) at Week 24 for Double-blind Group [ Time Frame: Baseline, up to 24 weeks ]FPG was obtained at baseline and at Week 24. The model-adjusted change from baseline was calculated using mixed-effects repeated measures analysis.
- Change From Baseline in Fasting Plasma Glucose (FPG) at Week 24 for High Glycemic Group [ Time Frame: Baseline, up to 24 weeks ]The change in FPG from baseline at Week 24 for High Glycemic Group was calculated by subtracting the mean FPG at baseline from the mean FPG at Week 24
- Change From Baseline in Systolic Blood Pressure (SBP) at Week 24 [ Time Frame: Baseline to week 24 ]Changes from baseline at Week 24 in SBP for the double-blind group and high glycemic group
- Proportion of Subjects Achieving HbA1c < 7% Over Time for Double-blind Group [ Time Frame: Baseline, up to 24 weeks ]The proportion of subjects who achieved HbA1c < 7% at 6, 12, 18 and 24 weeks were calculated based on the number of subjects with a value at each time point for each group. The model-adjusted proportion was calculated based on a logistic analysis using Generalized Estimating Equation (GEE) logistic regression that includes country, treatment, visit, treatment-by-visit interaction and the baseline HbA1c value as a fixed effect covariate. An unstructured correlation structure will be used, or autoregressive if the model with the unstructured structure does not converge.
- Proportion of Subjects Achieving HbA1c < 7% Over Time for High Glycemic Group [ Time Frame: Baseline, up to 24 weeks ]The proportion of subjects who achieved HbA1c < 7% at 6, 12, 18 and 24 weeks were calculated based on the number of subjects with a value at each time point for each group.
- Change in Body Mass From Baseline to Week 24 in Subjects With a BMI ≥ 25 kg/m2 for Double-blind Group [ Time Frame: Baseline to week 24 ]Changes in body mass from baseline to week 24 was calculated based on LS means for both bexagliflozin and placebo groups.
- Change in Body Mass From Baseline to Week 24 in Subjects With a BMI ≥ 25 kg/m2 for High Glycemic Group [ Time Frame: Baseline to week 24 ]The change in body mass from baseline at week 24 for High Glycemic group was calculated by subtracting the mean body mass at baseline from the mean body mass at week 24
- Change From Baseline in HbA1c Over Time in Double-blind Treatment Group [ Time Frame: Baseline, up to 24 weeks ]The change from baseline in HbA1c at 6, 12, 18 and 24 weeks was calculated based on the number of subjects with a value at each time point for each group. The model-adjusted change from baseline was calculated based on a mixed-effects repeated measures analysis that includes country, treatment, visit, treatment-by-visit interaction and the baseline HbA1c value as a fixed effect covariate.
- Change in HbA1c Over Time Among Subjects Who Have Baseline HbA1c of > 10.5% and ≤ 12.0% [ Time Frame: Baseline, up to 24 weeks ]The change from baseline in HbA1c at 6, 12, 18 and 24 weeks was calculated based on the number of subjects with a value at each time point in High Glycemic Group.
