Efficacy and Safety of the Insulin Glargine/Lixisenatide Fixed Ratio Combination (FRC) Versus GLP-1 Receptor Agonist in Patients With Type 2 Diabetes, With a FRC Extension Period

Sanofi514 enrolled

Overview

Primary Objective: To demonstrate the superiority of the insulin glargine/lixisenatide fixed ratio combination (FRC) versus GLP-1 receptor agonist (GLP-1 RA) in hemoglobin A1c (HbA1c) change. Secondary Objectives: To compare the overall efficacy and safety of the insulin glargine/lixisenatide FRC to GLP-1 RA on top of metformin (with or without pioglitazone, with or without sodium-glucose co-transporter 2 \[SGLT2\] inhibitor) in participants with type 2 diabetes. To evaluate safety, efficacy and other endpoints of FRC up to the end of the extension period.

The maximum duration for GLP1-RA participants was approximately 29 weeks: up to 2 week screening period, a 26 week treatment period (either randomized or uncontrolled), and a 3 or 9 day post-treatment safety follow-up period. Maximum duration for FRC participants was approximately 55 weeks: up to 2-week screening period, a 26-week randomized treatment period, a 26-week extension period and a 3-day post-treatment safety follow-up period. All primary and secondary efficacy, safety and other outcome measures were assessed at the end of the extension period.

Outcomes

Primary Outcomes

Change From Baseline in Glycated Hemoglobin (HbA1c) to Week 26: Core Period

Change in HbA1c was calculated by subtracting baseline value from Week 26 value. Adjusted least squares (LS) mean and standard error (SE) were obtained from Mixed-effect model with repeated measures (MMRM) to account for missing data using all available post baseline data during the 26 week treatment period.

Time frame: Baseline, Week 26
