The purpose of this study is to investigate the effect of bexagliflozin compared to placebo as an add-on therapy to metformin in lowering hemoglobin A1c (HbA1c) levels in subjects with type 2 diabetes mellitus (T2DM).
Approximately 300 subjects with inadequately controlled T2DM on metformin were to be recruited from the United States and Japan. Subjects were randomly assigned to receive bexagliflozin tablets, 20 mg, or bexagliflozin tablets, placebo, in a ratio of 1:1 once daily for 24 weeks. Subjects were to continue taking metformin for the duration of the study. The study also enrolled 50 subjects with extremely poorly controlled T2DM on metformin to receive open-label bexagliflozin tablets, 20 mg, for 24 weeks.
The subjects were required to meet the following criteria at the time of enrollment to be eligible for the study:
Subjects who met any of the following criteria were to be excluded from the study:
Drug: Bexagliflozin tablets, 20 mg
Drug: Bexagliflozin tablets, placebo
Drug: Bexagliflozin tablets, 20 mg
Each subject will receive bexagliflozin, 20 mg once daily for the duration of the study.
Also known as: EGT0001442, EGT0001474
Each subject will receive placebo (inactive tablet) once daily for the duration of the study.
Each subject will receive bexagliflozin, 20 mg once daily for the duration of the study.

Change From Baseline in HbA1c at Week 24 for Double-blind Group
HbA1c was obtained at baseline and at Week 24. The model-adjusted change from baseline was calculated using mixed-effects repeated measures analysis.
Time frame: Baseline to week 24
Change From Baseline in HbA1c at Week 24 for High Glycemic Group
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
Time frame: Baseline to week 24
Change From Baseline in Fasting Plasma Glucose (FPG) at Week 24 for Double-blind Group
FPG was obtained at baseline and at Week 24. The model-adjusted change from baseline was calculated using mixed-effects repeated measures analysis.
Time frame: Baseline, up to 24 weeks
Change From Baseline in Fasting Plasma Glucose (FPG) at Week 24 for High Glycemic Group
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
Time frame: Baseline, up to 24 weeks
Change From Baseline in Systolic Blood Pressure (SBP) at Week 24
Changes from baseline at Week 24 in SBP for the double-blind group and high glycemic group
Time frame: Baseline to week 24
Proportion of Subjects Achieving HbA1c < 7% Over Time for Double-blind Group
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.
Time frame: Baseline, up to 24 weeks
Proportion of Subjects Achieving HbA1c < 7% Over Time for High Glycemic Group
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.
Time frame: Baseline, up to 24 weeks
Change in Body Mass From Baseline to Week 24 in Subjects With a BMI ≥ 25 kg/m2 for Double-blind Group
Changes in body mass from baseline to week 24 was calculated based on LS means for both bexagliflozin and placebo groups.
Time frame: Baseline to week 24
Change in Body Mass From Baseline to Week 24 in Subjects With a BMI ≥ 25 kg/m2 for High Glycemic Group
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
Time frame: Baseline to week 24
Change From Baseline in HbA1c Over Time in Double-blind Treatment Group
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.
Time frame: Baseline, up to 24 weeks
Change in HbA1c Over Time Among Subjects Who Have Baseline HbA1c of > 10.5% and ≤ 12.0%
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.
Time frame: Baseline, up to 24 weeks
