Conditions: Diabetes Mellitus Type 2
Keywords: hyperglycemia GLP-1 pioglitazone
Allocation: RANDOMIZED | Intervention model: PARALLEL
Enrollment: 484
Healthy volunteers: no

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

Secondary objectives are to assess the effects of lixisenatide when added to pioglitazone on the percentage of patients reaching HbA1c less than 7 percent (%) and less than or equal to 6.5%, fasting plasma glucose (FPG), body weight, beta-cell function (assessed by homeostatic model assessment of beta-cell function \[HOMA-beta\]), and on fasting plasma insulin (FPI), 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 schedule date of Week 76 visit (Visit 25) for the last randomized patients.

Arms:
arm 1: 2-step initiation regimen of lixisenatide: 10 microgram (mcg) once daily (QD) for 1 week, followed by 15 mcg QD for 1 week, then 20 mcg QD up to the end of treatment. arm 2: 2-step initiation regimen of volume matching placebo: 10 mcg QD for 1 week, followed by 15 mcg QD for 1 week, then 20 mcg QD up to the end of treatment.

Interventions: intervention 1: Lixisenatide (AVE0010) intervention 2: Placebo intervention 3: Pen auto-injector intervention 4: Pioglitazone intervention 5: Metformin
Intervention descriptions: intervention 1: Self-administered by subcutaneous injections once daily within the hour preceding breakfast. intervention 2: Self-administered by subcutaneous injections once daily within the hour preceding breakfast. intervention 3: None intervention 4: Dose to be kept stable. intervention 5: Metformin, if given to be continued at stable dose (at least 1.5 gram per day) up to the end of treatment.
