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.

Condition or Disease Intervention/Treatment Phase
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.

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

  1. 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.

Arm/Group Description Following a 2-week run-in period, participants were randomized to matching placebo administered as 2 tablets, 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. 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.

Statistical Analysis 1
Statistical Analysis Overview Comparison Group Selection Placebo, Sotagliflozin 400 mg
Comments The change from baseline to Week 26 is analyzed using ANCOVA model with treatment groups, randomization strata of HbA1c (≤8.5, >8.5%) at screening, randomization strata of Metformin use at screening, randomization strata of mean SBP (<130, ≥130 mmHg) at screening, and country as fixed effects, and baseline weight as a covariate.
