Efficacy and Safety of Sotagliflozin Versus Placebo in Participants With Type 2 Diabetes Mellitus on Background of Sulfonylurea Alone or With Metformin
Study Details
Study Description
Brief Summary
Primary Objective:
To demonstrate the superiority of Sotagliflozin 400 milligrams (mg) versus placebo on Hemoglobin A1c (HbA1c) reduction at Week 26 in participant with type 2 diabetes (T2D) who have inadequate glycemic control with a Sulfonylurea alone or in combination with Metformin.
Secondary Objectives:
-
To compare Sotagliflozin 400 mg versus placebo based on:
-
Change from baseline in fasting plasma glucose (FPG).
-
Change from baseline in systolic blood pressure (SBP) for participants with baseline SBP ≥130 millimeter of mercury (mm Hg).
-
Change from baseline in SBP for all participants.
-
Change from baseline in body weight.
-
Percentage of participants with HbA1c <6.5% and <7.0%.
-
To evaluate the safety of Sotagliflozin 400 mg versus placebo throughout the 79-week trial.

Phase 3 |
Detailed Description
The duration per participants is up to 85 weeks, including a Screening Period consisting of a Screening phase of up to 2 weeks and a 2-week single-blind Run-in phase, a 26-week double blind Core Treatment Period, a 53 week double blind Extension, and a 2-week post treatment Follow-up period to collect safety information.

Arms and Interventions
Arm | Intervention/Treatment |
---|---|
Experimental: Sotagliflozin 400 mg Following a 2-week run-in phase, participants received two Sotagliflozin tablets of 200 mg, orally once daily, before the first meal of the day plus Metformin and Sulfonylurea as prescribed for up to 26 weeks in the Core Treatment Period. Participants were eligible to continue treatment in the Extension Period. The total treatment duration was planned for up to 79 weeks. |

Outcome Measures
Primary Outcome Measures
- Change From Baseline in Hemoglobin A1c (HbA1c) at Week 26 [Baseline to Week 26]
Missing data are imputed using the retrieved dropouts imputation method. An analysis of covariance (ANCOVA) model was used for the analysis.
Secondary Outcome Measures
- Change From Baseline in Fasting Plasma Glucose (FPG) at Week 26 [Baseline to Week 26]
Missing data are imputed using the retrieved dropouts imputation method. An ANCOVA model was used for the analysis.
- Change From Baseline in Systolic Blood Pressure (SBP) for Participants With Baseline SBP ≥130 mmHg [Baseline to Week 12]
Missing data are imputed using the washout imputation method under the missing, not at random framework. An ANCOVA model was used for the analysis.
- Change From Baseline in SBP at Week 12 for All Participants [Baseline to Week 12]
Missing data are imputed using washout imputation method under the missing not at random framework. An ANCOVA model was used for the analysis.
- Change From Baseline in Body Weight at Week 26 [Baseline to Week 26]
Missing data are imputed using the retrieved dropouts imputation method. An ANCOVA model was used for the analysis.
- Percentage of Participants With HbA1c <6.5% at Week 26 [Week 26]
- Percentage of Participants With HbA1c <7.0% at Week 26 [Week 26]
Other Outcome Measures
- Percentage of Participants With Hypoglycemic Events [Up to 79 weeks in the treatment period]
Percentage of participants with hypoglycemic events are reported for the following 3 categories: Any hypoglycemia (as reported in the Electronic Case Report Form); Documented symptomatic hypoglycemia [typical symptoms of hypoglycemia (increased sweating, nervousness, asthenia/weakness, tremor, dizziness, increased appetite, palpitations, headache, sleep disorder, confusion, seizures, unconsciousness, and/or coma) and plasma glucose ≤ 70 mg/dL (3.9 mmol/L)]; Severe [an event requiring assistance of another person to actively administer carbohydrate, glucagon, intravenous glucose or other resuscitative actions] or documented symptomatic hypoglycemia [typical symptoms of hypoglycemia and plasma glucose ≤ 70 mg/dL]. Participants may be reported in more than one category.
