  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 sulfonylurea without or with 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 sulfonylurea with or without metformin on glycemic control in terms of glycosylated hemoglobin (HbA1c) reduction (absolute change) at Week 24.

The secondary objectives are to assess the effects of lixisenatide on percentage of patients reaching HbA1c less than (<) 7 percent (%); percentage of patients reaching HbA1c less than or equal to (<=) 6.5%; body weight; fasting plasma glucose (FPG); beta-cell function assessed by homeostasis model assessment (HOMA) beta; 2-hour postprandial plasma glucose (PPG), glucagon, insulin, proinsulin, and C-peptide after a standardized meal challenge test in a sub-study in all patients in selected centers; to evaluate safety, tolerability, pharmacokinetics (PK) and anti-lixisenatide antibody development.

Primary Outcome Measures:
  • Absolute 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.


Secondary Outcome Measures:
  • Change From Baseline in 2-Hour Postprandial Plasma Glucose (PPG) at Week 24 [ Time Frame: Baseline, Week 24 ] [ Designated as safety issue: No ]
    The 2-hour PPG blood sample was drawn 2 hours after start of a standardized meal (standardized meal challenge test performed in selected sites). 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 last dosing day 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 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.

    Routine fasting self-monitored 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.
