Females who were surgically sterile (hysterectomy, oophorectomy) or postmenopausal (absence of menses greater than 12 months) were eligible if they had tested negative for pregnancy at screening.

2. a) Had a history of T2DM with an HbA1c level of ≥ 7.5% and ≤ 10.5% at screening, or b) Had a history of T2DM with an HbA1c level of >10.5% and ≤ 12.0% at screening

3. Had been prescribed a stable dose of metformin (≥1500 mg per day in the US or ≥ 1000 mg per day in Japan) as their sole anti-diabetic medication

4. Had a body mass index (BMI) ≤ 45 kg m-2

Subjects who met any of the following criteria were to be excluded from the study:

1. Had a diagnosis of type 1 diabetes mellitus or maturity-onset diabetes of the young

2. Were pregnant or breastfeeding

3. Had one or more hemoglobin alleles that affect HbA1c measurement

4. Had a history of genitourinary tract infection (e.g., UTI, GMI, vaginitis, balanitis) within 6 weeks of screening or a history of ≥ 3 genitourinary infections requiring treatment within 6 months of screening

5. Had an estimated glomerular filtration rate (eGFR), as calculated by the modification of diet in renal disease study equation (MDRD), < 60 mL min-1 per 1.73 m2

6. Had a sitting systolic blood pressure >180 mmHg or a sitting diastolic blood pressure > 110 mmHg at screening

7. Had exposure to hypoglycemic agent(s) other than metformin during the 8 weeks prior to screening

8. Had a history of illicit drug use or alcohol abuse in the past 2 years

9. Had a life expectancy < 2 years

10. Had a diagnosis of New York Heart Association (NYHA) Class IV heart failure within 3 months of screening

13. Had a previous exposure to bexagliflozin or EGT0001474

14. Had a history of SGLT2 inhibitor treatment

15. Were participating in another interventional trial

16. Were not able to comply with the study scheduled visits

17. Had any condition, disease, disorder, or clinically relevant abnormality that, in the opinion of the primary investigator, would jeopardize the subject's appropriate participation in this study or obscure the effects of treatment

18. Had an alanine aminotransferase (ALT) or aspartate aminotransferase (AST) ≥ 2.5 × ULN or total bilirubin ≥ 1.5 × ULN at screening
