GLP-1 Receptor Agonist Lixisenatide in Patients With Type 2 Diabetes for Glycemic Control and Safety Evaluation, on Top of Metformin

Overview[ - collapse ][ - ]

Purpose The purpose of this study is to evaluate the benefits and risks of lixisenatide (AVE0010), in comparison to placebo, as an add-on treatment to metformin, over a period of 24 weeks of treatment, followed by an extension. The primary objective is to assess the effects of lixisenatide when added to metformin on glycemic control in terms of glycosylated hemoglobin (HbA1c) reduction when it is used in two steps dose titration regimen at Week 24. Secondary objectives are to assess the effects of lixisenatide when added to metformin on glycemic control in comparison to placebo in terms of HbA1c reduction when it is used in a one-step dose titration regimen, the percentage of patients with HbA1c less than 7 percent or less than or equal to 6.5%, body weight, fasting plasma glucose (FPG); to assess the safety, tolerability, pharmacokinetics (PK) and anti-lixisenatide antibody development.

Current Primary Outcome MeasuresAbsolute Change From Baseline in Glycosylated Hemoglobin (HbA1c) at Week 24 [Time Frame: Baseline, Week 24] [Designated as safety issue: No]Absolute change = HbA1c value at Week 24 minus HbA1c value at baseline. The on-treatment period for this efficacy variable is time from the first dose of study drug and up to 3 days after the last dose of study drug, on or before Visit 12 (Week 24) or Day 169 if Visit 12 is not available, and before the introduction of rescue therapy. For a patient to be included in mITT population, both baseline and at least 1 post baseline assessment for at least 1 efficacy variable, were required.
Current Secondary Outcome Measures
  • Change From Baseline in Fasting Plasma Glucose (FPG) at Week 24 [Time Frame: Baseline, Week 24] [Designated as safety issue: No]Change was calculated by subtracting baseline value from Week 24 value. The on-treatment period for this efficacy variable is time from the first dose of study drug and up to 1 day after the last dose of study drug, on or before Visit 12 (Week 24) or Day 169 if Visit 12 is not available, and before the introduction of rescue therapy. For a patient to be included in mITT population, both baseline and at least 1 post baseline assessment for at least 1 efficacy variable, were required.
  • Change From Baseline in Body Weight at Week 24 [Time Frame: Baseline, Week 24] [Designated as safety issue: No]Change was calculated by subtracting baseline value from Week 24 value. The on-treatment period for this efficacy variable is time from the first dose of study drug and up to 3 days after the last dose of study drug, on or before Visit 12 (Week 24) or Day 169 if Visit 12 is not available, and before the introduction of rescue therapy. For a patient to be included in mITT population, both baseline and at least 1 post baseline assessment for at least 1 efficacy variable, were required.
  • Percentage of Patients With Glycosylated Hemoglobin (HbA1c) Level Less Than 7% at Week 24 [Time Frame: Week 24] [Designated as safety issue: No]The on-treatment period for this efficacy variable is time from the first dose of study drug and up to 3 days after the last dose of study drug, on or before Visit 12 (Week 24) or Day 169 if Visit 12 is not available, and before the introduction of rescue therapy. For a patient to be included in mITT population, both baseline and at least 1 post baseline assessment for at least 1 efficacy variable, were required.
  • Percentage of Patients With Glycosylated Hemoglobin (HbA1c) Level Less Than or Equal to 6.5% at Week 24 [Time Frame: Week 24] [Designated as safety issue: No]The on-treatment period for this efficacy variable is time from the first dose of study drug and up to 3 days after the last dose of study drug, on or before Visit 12 (Week 24) or Day 169 if Visit 12 is not available, and before the introduction of rescue therapy. For a patient to be included in mITT population, both baseline and at least 1 post baseline assessment for at least 1 efficacy variable, were required.
  • Percentage of Patients Requiring Rescue Therapy During Main 24-Week Period [Time Frame: Baseline up to Week 24] [Designated as safety issue: No]Routine fasting self-measured plasma glucose (SMPG) and central laboratory FPG (and HbA1c after week 12) values were used to determine the requirement of rescue medication. If fasting SMPG value exceeded the specified limit for 3 consecutive days, the central laboratory FPG (and HbA1c after week 12) were performed. Threshold values - from baseline to Week 8: fasting SMPG/FPG >270 milligram/deciliter (mg/dL) (15.0 mmol/L), from Week 8 to Week 12: fasting SMPG/FPG >240 mg/dL (13.3 mmol/L), and from Week 12 to Week 24: fasting SMPG/FPG >200 mg/dL (11.1 mmol/L) or HbA1c >8.5%. For a patient to be included in mITT population, both baseline and at least 1 post baseline assessment for at least 1 efficacy variable, were required.

Brief TitleGLP-1 Receptor Agonist Lixisenatide in Patients With Type 2 Diabetes for Glycemic Control and Safety Evaluation, on Top of Metformin
Official TitleA Randomized, Double-blind, Placebo-controlled, Parallel-group, Multicenter, 24-week Study Followed by an Extension Assessing the Efficacy and Safety of AVE0010 in Two Titration Regimens on Top of Metformin in Patients With Type 2 Diabetes Not Adequately Controlled With Metformin
Brief Summary
The purpose of this study is to evaluate the benefits and risks of lixisenatide (AVE0010),
in comparison to placebo, as an add-on treatment to metformin, over a period of 24 weeks of
treatment, followed by an extension.

The primary objective is to assess the effects of lixisenatide when added to metformin on
glycemic control in terms of glycosylated hemoglobin (HbA1c) reduction when it is used in
two steps dose titration regimen at Week 24.

Secondary objectives are to assess the effects of lixisenatide when added to metformin on
glycemic control in comparison to placebo in terms of HbA1c reduction when it is used in a
one-step dose titration regimen, the percentage of patients with HbA1c less than 7 percent
or less than or equal to 6.5%, body weight, fasting plasma glucose (FPG); to assess the
safety, tolerability, pharmacokinetics (PK) and anti-lixisenatide antibody development.
Detailed Description
Patients who complete the 24-week main double-blind treatment would undergo a variable
double-blind extension treatment, which ends for all patients at approximately the scheduled
date of Week 76 visit (Visit 25) for the last randomized patients.
