Study summary

What the protocol is testing.

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 as an add-on treatment to metformin in terms of glycosylated hemoglobin (HbA1c) reduction (absolute change) at Week 24. The secondary objectives are to assess the effect of lixisenatide, in comparison to placebo, when administered in the evening within 1 hour prior to the meal in terms of HbA1c reduction, percentage of patients reaching HbA1c less than (\<) 7 percent (%), percentage of patients reaching HbA1c less than or equal to 6.5%, fasting plasma glucose (FPG), plasma glucose, plasma insulin, C-peptide, glucagon, and proinsulin during a 2-hour standardized meal test (only in morning injection arms), body weight, beta-cell function assessed by homeostasis model assessment (HOMA)-beta, fasting plasma insulin (FPI) and adiponectin; to evaluate safety, tolerability, pharmacokinetics (PK) and anti-lixisenatide antibody development, beta-cell function 4 weeks after study drug discontinuation (only in patients from the morning injection arms in some selected centers).

Full 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 patient.

Outcomes

What the study measures.

Primary outcomes

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 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 Modified Intent-to-treat (mITT) population, both baseline and at least 1 post baseline assessment for at least 1 efficacy variable, were required.

Secondary outcomes

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 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 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. The on-treatment period for this efficacy variable is time from the first dose of study drug and up to the last dosing day of the 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.

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 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.

Change From Baseline in Fasting Plasma Insulin (FPI) 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 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 2-Hour Postprandial Plasma Insulin (PPI) 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 time from the first dose of study drug and up to the last dosing day of the 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.

Change From Baseline in Fasting Proinsulin 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 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.
