Type 2 Diabetes Mellitus | Drug: Bexagliflozin Drug: Placebo | Phase 3 |
This was a phase 3, multi-center, randomized, double-blind, placebo-controlled, parallel-group study to evaluate the efficacy and safety of once daily oral administration of bexagliflozin tablets, 20 mg or placebo tablets, in male and female subjects with T2DM who were treatment-naïve or previously treated with 1 oral hypoglycemic agent (OHA).
Prospective subjects being treated with one OHA were eligible if they had an HbA1c between 6.5% and 10.0% and were willing to complete a 6-week washout. Individuals taking thiazolidinediones were not eligible for the study. All eligible subjects were to start a 2-week placebo run-in period. Subjects who missed no more than 1 dose of the run-in medication, had fasting blood glucose values ≥ 250 mg/dL on no more than two consecutive days, and had an HbA1c level between 7.0% and 10.5% and a fasting glucose level < 250 mg/dL after the run-in period were eligible for randomization.
Two hundred and ten (210) subjects were planned to be randomly assigned to receive oral bexagliflozin tablets, 20 mg or placebo, in a 2:1 ratio once daily for 24 weeks. Subjects with uncontrolled hyperglycemia based on blood glucose levels could receive additional approved anti-diabetic medications. Treatment group assignment at the start of the treatment period was stratified by baseline HbA1c level and background anti-diabetes treatment status (treatment naïve or not).
Each subject was contacted by telephone at week 2 and was instructed to return to the clinic at weeks 6, 12, 18, and 24 for efficacy assessment and safety monitoring. Subjects returned to the clinic for a follow-up visit at week 26 or 2 weeks after the last dose of investigational product if the subject terminated prior to week 24.

- Change in HbA1c From Baseline at Week 24 [ Time Frame: 24 weeks ]Glycated hemoglobin A1c (%) was measured using an HPLC method in the laboratories that had completed NGSP Level I laboratory certification and were traceable to the Diabetes Control and Complications Trial (DCCT) reference method.
- Change in Systolic Blood Pressure (SBP) From Baseline at Week 24 [ Time Frame: 24 weeks ]Blood pressure (BP) measurements are obtained using a calibrated sphygmomanometer in sitting, supine and standing positions. The left arm and same cuff sizes should be used for each measurement at all visits. If the left arm cannot be used at the screening visit or during the study for BP measurements, the reason should be documented and the right arm should be used for BP measurements for all subsequent visits.
- Change in Body Weight From Baseline at Week 24 in Subjects With a BMI ≥ 25 Kg/m2 [ Time Frame: 24 weeks ]The body weight was obtained using a calibrated scale as part of complete physical examination or abbreviated physical examination.
- Change From Baseline in Fasting Plasma Glucose (FPG) Over Time [ Time Frame: 24 weeks ]The fasting plasma glucose (FPG) is measured at each study visit. The subject must have fasted for approximately 10 hours prior to the blood draw to ensure that the FPG value is truly a fasting sample.
- Change From Baseline of HbA1c From Baseline Over Time [ Time Frame: 24 weeks ]Glycated hemoglobin A1c (%) was measured using an HPLC method in the laboratories that had completed NGSP Level I laboratory certification and were traceable to the Diabetes Control and Complications Trial (DCCT) reference method.
- Proportion of Subjects Who Achieve an HbA1c < 7% [ Time Frame: Up to 24 weeks ]Glycated hemoglobin A1c (%) was measured using an HPLC method in the laboratories that had completed NGSP Level I laboratory certification and were traceable to the Diabetes Control and Complications Trial (DCCT) reference method.
