Brief Summary:

The purpose of the study is to evaluate the benefits and risks of lixisenatide (AVE0010), in comparison to placebo, as an add-on treatment to insulin glargine and metformin with or without thiazolidinediones (TZDs), over a period of 24 weeks of treatment.

The primary objective is to assess the effects of lixisenatide in comparison to placebo, when added to insulin glargine and 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 the percentage of patients reaching HbA1c less than (<) 7 percent (%) and less than or equal to (<=) 6.5%, plasma glucose (fasting, postprandial during a standardized meal challenge test, 7-point self monitored profiles), body weight, insulin glargine doses, to evaluate safety and tolerability (including anti-lixisenatide antibody assessment), and to assess the impact on treatment satisfaction using the Diabetes Treatment Satisfaction Questionnaire (state) (DTSQs) in the participating countries where it is validated.


Condition or disease Intervention/treatment Phase
Type 2 Diabetes Mellitus Drug: Lixisenatide (AVE0010) Drug: Placebo Drug: Insulin glargine Device: Pen auto-injector Drug: Metformin Drug: Thiazolidinedione (TZD) Phase 3

Detailed Description:

The study comprises 3 periods:

  • An up to 14-week screening period, which includes an up to 2-week screening phase and a 12-week run-in phase with introduction and titration of insulin glargine on top of metformin +/-TZDs.
  • At the end of the run-in phase, patients whose HbA1c (centralized assay) is greater than or equal to (>=) 7% and less than or equal to (<=) 9% and whose mean fasting self-monitored plasma glucose (SMPG) calculated from the self measurements for the 7 days prior to Visit 12 (Week -1) is <=140 milligram per deciliter (mg/dL) (7.8 millimole per liter [mmol/L]), would enter a 24-week double-blind randomized treatment period comparing lixisenatide to placebo (on top of insulin glargine + metformin +/- TZDs).
  • A 3-day safety follow up period.

Maximum duration is of 39 weeks +/- 7 days.

Primary Outcome Measures :
  1. Absolute Change From Baseline in Glycosylated Hemoglobin (HbA1c) at Week 24 [ Time Frame: Baseline, Week 24 ]
    Absolute change = HbA1c value at Week 24 minus HbA1c value at baseline. The on-treatment period for this efficacy variable is the time from the first dose of study drug up to 14 days after the last dose of study drug or up to the introduction of rescue therapy, whichever is the earliest. 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 :
  1. Change From Baseline in 2-Hour Postprandial Plasma Glucose (PPG) at Week 24 [ Time Frame: Baseline, Week 24 ]
    The 2-hour PPG test measured blood glucose 2 hours after eating a standardized meal. Change was calculated by subtracting baseline value from Week 24 value. The on-treatment period for this efficacy variable is the time from the first dose of study drug up to the last dosing day of study drug or up to the introduction of rescue therapy, whichever is the earliest. 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.

  2. Change From Baseline in Glucose Excursion at Week 24 [ Time Frame: Baseline, Week 24 ]
    Glucose excursion = 2-hour PPG minus plasma glucose 30 minutes prior to the standardized meal test, before study drug administration.

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.

  3. Change From Baseline in Average 7-Point Self Monitored Plasma Glucose (SMPG) Profile at Week 24 [ Time Frame: Baseline, Week 24 ]
    Patients recorded a 7-point plasma glucose profile measured before and 2 hours after each meal and at bedtime once in a week and the average value for the 7-time points was calculated. The on-treatment period for this efficacy variable is the time from the first dose of study drug up to the last dosing day of study drug or up to the introduction of rescue therapy, whichever is the earliest. 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.

  4. Change From Baseline in Body Weight at Week 24 [ Time Frame: Baseline, Week 24 ]
    Change was calculated by subtracting baseline value from Week 24 value. The on-treatment period for this efficacy variable is the time from the first dose of study drug up to 3 days after the last dose of study drug or up to the introduction of rescue therapy, whichever is the earliest. 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.

  5. Change From Baseline in Average Insulin Glargine Daily Dose at Week 24 [ Time Frame: Baseline, Week 24 ]
    Change was calculated by subtracting the baseline value from Week 24 value. The on-treatment period for this efficacy variable is the time from the first dose of study drug up to the last dosing day of study drug or up to the introduction of rescue therapy, whichever is the earliest. 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.

  6. Change From Baseline in Fasting Plasma Glucose (FPG) at Week 24 [ Time Frame: Baseline, Week 24 ]
    Change was calculated by subtracting baseline value from Week 24 value. The on-treatment period for this efficacy variable is the time from the first dose of study drug up to 1 day after the last dose of study drug or up to the introduction of rescue therapy, whichever is the earliest. 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.

  7. Percentage of Patients With Glycosylated Hemoglobin (HbA1c) Level Less Than 7% at Week 24 [ Time Frame: Week 24 ]
    The on-treatment period for this efficacy variable is the time from the first dose of study drug up to 14 days after the last dose of study drug or up to the introduction of rescue therapy, whichever is the earliest. 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.

  8. Percentage of Patients With Glycosylated Hemoglobin (HbA1c) Level Less Than or Equal to 6.5% at Week 24 [ Time Frame: Week 24 ]
    The on-treatment period for this efficacy variable is the time from the first dose of study drug up to 14 days after the last dose of study drug or up to the introduction of rescue therapy, whichever is the earliest. 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.

  9. Percentage of Patients Requiring Rescue Therapy During the Double-blind Period [ Time Frame: Baseline up to Week 24 ]
    Routine fasting SMPG, central laboratory FPG and HbA1c 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 were performed. Threshold values - from baseline to Week 8: fasting SMPG/FPG >200 milligram/deciliter (mg/dL) (11.1 mmol/L) or HbA1c >9%, from Week 8 to Week 24: fasting SMPG/FPG >180 mg/dL (10.0 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.

  10. Change From Baseline in Treatment Satisfaction Score (Sum of Items 1, 4, 5, 6, 7 and 8 of DTSQ) at Week 24 [ Time Frame: Baseline, Week 24 ]
    Change was calculated by subtracting baseline value from Week 24 value. DTSQ: 8-item questionnaire to assess treatment satisfaction and patient perception of hyper and hypoglycemia. Each question (Q) scored on a Likert scale from 0 to 6. Six items (Q1 and 4-8; higher score = more satisfaction) measured treatment satisfaction and were summed to calculate treatment satisfaction score which ranged from 0 (very dissatisfied) to 36 (very satisfied). Two items (Q2 and 3), which were not included, measured perceived hyperglycemia and hypoglycemia, respectively and lower scores represented good perceived blood glucose control. The on-treatment period for this efficacy variable is the time from the first dose of study drug up to 3 days after the last dose of study drug or up to the introduction of rescue therapy, whichever is the earliest. 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.


Other Outcome Measures:
  1. Percentage of Patients With at Least 5% Weight Loss From Baseline at Week 24 [ Time Frame: Baseline, Week 24 ]
    The on-treatment period for this efficacy variable is the time from the first dose of study drug up to 3 days after the last dose of study drug or up to the introduction of rescue therapy, whichever is the earliest. 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.

  2. Number of Patients With Symptomatic Hypoglycemia and Severe Symptomatic Hypoglycemia [ Time Frame: First dose of study drug up to 3 days after the last dose administration ]
    Symptomatic hypoglycemia was an event with clinical symptoms that were considered to result from a hypoglycemic episode with an accompanying plasma glucose less than 60 mg/dL (3.3 mmol/L) or associated with prompt recovery after oral carbohydrate, intravenous glucose, or glucagon administration if no plasma glucose measurement was available. Severe symptomatic hypoglycemia was symptomatic hypoglycemia event in which the patient required the assistance of another person and was associated with either a plasma glucose level below 36 mg/dL (2.0 mmol/L) or prompt recovery after oral carbohydrate, intravenous glucose, or glucagon administration, if no plasma glucose measurement was available.
