Detailed Description
The phase 3, double-blind, placebo-controlled parallel-group study was conducted at investigative sites in the US, Japan, France and Spain. Approximately 300 subjects were to be randomly assigned to receive bexagliflozin tablets, 20 mg, or placebo in equal ratio for 24 weeks.
The study was to enrolled male and female participants who had T2DM with an HbA1c between 7.0 and 10.5% (inclusive) and stage 3 chronic kidney disease (CKD) as defined by an eGFR of ≥ 30 and< 60 mL min-1 per 1.73 m2 at the screening visit and one additional time of measurement between 1 and 12 months prior to screening. Subjects were either treatment naïve or were treated with a stable regimen of anti-diabetic medications.
All eligible subjects were to enter a one-week single-blind, placebo run-in period. Subjects who were compliant in taking run-in medication, had screening eGFR ≥ 30 and< 60 mL min-1 per 1.73 m2, and had stable GFR (no more than 20% change in eGFR between a historical value and the value determined at the screening visit) were eligible for randomization. Randomization was stratified by HbA1c level (7.0 to 8.5% or 8.6 to 10.5%), anti-diabetic treatment regimen and eGFR (30 - 44 mL min-1 per 1.73 m2 or 45 - 59 mL min-1 per 1.73 m2). At least 135 subjects in each of the eGFR groups were planned.
Study subjects were to schedule clinic visits at weeks 2, 6, 12, 18, and 24 for safety and efficacy evaluation. At weeks 2 and 18, the visits were to be conducted via phone interviews unless an in-person visit was considered clinically advisable. A final follow-up visit was to be conducted at week 26 or two weeks after the last dose of investigational product if the subject withdrew prior to week 24.

Each subject was required to meet the following criteria at the time of enrollment to be eligible for the study:
- To have been male or non-pregnant female ≥ 20 years of age. Women of childbearing potential were required to agree to use contraception throughout the study to avoid any possible pregnancy. Females who were surgically sterile (hysterectomy, oophorectomy) or postmenopausal (absence of menses for greater than 12 months and age > 45 years) were eligible if they tested negative on the urine pregnancy test.

- To have been treatment naïve or to have been treated with a stable regimen of anti-diabetic medications. At the time of screening, the doses and frequency of all anti-diabetic medications were to have been stable for 8 weeks.
- To have had an eGFR ≥ 30 and < 60 mL min-1 per 1.73 m2 at 2 time points: screening (V1), and 1 additional time point between 1 and 12 months of screening (may be obtained from available medical records). The eGFR was calculated by the MDRD equation.
- To have had a body mass index (BMI) ≤ 45 kg per m2 (inclusive).
- To have been taking stable doses of medications for hypertension or hyperlipidemia (if applicable) for at least 30 days prior to randomization
- To have had stable eGFR between the historic value and day of screening (no more than 20% change in eGFR between the most recent historical value and the value determined at the screening visit V1).
9.3.2 Exclusion Criteria
Potential participants who exhibited any of the following characteristics were excluded from the study:
- A diagnosis of type 1 diabetes mellitus or maturity-onset diabetes of the young (MODY)
- A hemoglobinopathy that could affect HbA1c measurement

- A history of MI, stroke or hospitalization for heart failure, or hospitalization for unstable angina in the prior 3 months
- Evidence of NYHA class IV heart failure at screening or randomization
- A history of taking an SGLT2 inhibitor within 3 months of screening
- Any condition, disease, disorder, or clinically relevant laboratory abnormality that, in the opinion of the PI, would jeopardize the subject's appropriate participation in this study or obscure the effects of treatment
- A current status of pregnancy or breastfeeding
- A current status of renal replacement therapy (peritoneal or hemodialysis) or a history of renal transplantation
- A corrected serum calcium < 8 mg dL-1 at screening (V1) or randomization (V3)
- Uncontrolled hypertension (systolic blood pressure >170 mm Hg or diastolic blood pressure >110 mm Hg)
- Participation in another interventional trial or exposure to an investigational drug within 30 days or 7 half-lives of screening, whichever was longer
- Previous exposure to bexagliflozin or EGT0001474
- Evidence of having skipped dosing more than once during the run-in period
- A fasting blood glucose value during the run-in period ≥ 250 mg dL-1 (13.9 mmol L-1) associated with severe clinical signs or symptoms of hyperglycemia
- Any episode of symptomatic hypoglycemia during the run-in period in which symptoms were severe
