Brief Summary:

Primary Objective:

To demonstrate the superiority of Sotagliflozin 400 milligrams (mg) versus placebo on hemoglobin A1c (HbA1c) reduction in participants with type 2 diabetes (T2D) who have inadequate glycemic control on diet and exercise.

Secondary Objectives:

  • To compare Sotagliflozin 400 mg versus placebo based on:
  • Change from baseline in 2-hour postprandial glucose (PPG) following a mixed meal.
  • Change from baseline in fasting plasma glucose (FPG).
  • Change from baseline in systolic blood pressure (SBP) for participants with baseline SBP ≥130 millimeter per mercury (mmHg).
  • Change from baseline in SBP for all participants.
  • Change from baseline in body weight.
  • Proportion of participants with HbA1c <6.5%, <7.0%.
  • To compare Sotagliflozin 200 mg versus placebo based on:
  • Change from baseline in HbA1c.
  • Change from baseline in 2-hour postprandial glucose (PPG) following a mixed meal.
  • Change from baseline in body weight.
  • Change from baseline in SBP for all participants.
  • To evaluate the safety of Sotagliflozin 400 and 200 mg versus placebo.

Condition or disease Intervention/treatment Phase
