Efficacy and Safety of Sotagliflozin Versus Placebo in Chinese Patients With Type 2 Diabetes Mellitus Not Adequately Controlled by Diet and Exercise

Primary Objective: To demonstrate the superiority of sotagliflozin dose 1 versus placebo on hemoglobin A1c (HbA1c) reduction in Chinese patients with type 2 diabetes (T2D) who have inadequate glycemic control on diet and exercise. Secondary Objectives: * To compare sotagliflozin dose 1 versus placebo for change in 2-hour postprandial glucose (PPG) following a mixed meal tolerance test (MMTT), change in fasting plasma glucose (FPG), and change in body weight. * To compare sotagliflozin dose 2 versus placebo for change in HbA1c, change in 2-hour PPG following a MMTT, change in FPG, and change in body weight. * To compare sotagliflozin dose 2 and sotagliflozin dose 1 versus placebo for change in systolic blood pressure (SBP) for all patients, and change in SBP for patients with baseline SBP ≥130 mmHg. * To evaluate the safety of sotagliflozin dose 2 and sotagliflozin dose 1 versus placebo.
