- Sanofi
- Brief Summary
The purpose of the study is to compare the pharmacodynamic effects of lixisenatide (AVE0010), in comparison to liraglutide, as an add-on treatment to metformin, over a period of 4 weeks of treatment.
The primary objective is to assess the effects of lixisenatide, in comparison to liraglutide, in reducing postprandial plasma glucose (PPG) assessed as area under the plasma glucose concentration curve (AUC) after a standardized breakfast at Week 4.
The secondary objectives are to assess the effects of lixisenatide on the maximum PPG excursion, and on the changes in insulin, pro-insulin, C-peptide and glucagon plasma concentrations following a standardized breakfast, 24-hour profile of plasma glucose, glycosylated hemoglobin (HbA1c), satiety markers (obestatin, peptide YY \[PYY3-36\] and oxyntomodulin); and to assess the clinical and laboratory safety profile.
- Detailed Description
The duration of the study for each patient is up to 7 weeks including a screening period up to 2 weeks, a treatment period of 4 weeks (Day 1 to Day 28), and an end-of-study visit 7 +/- 2 days after last study drug administration.

Name Time Method Change From Baseline in Area Under the Plasma Glucose Concentration Curve From Time 0.5 Hours to 4.5 Hours (GLU-AUC0:30-4:30h) at Day 28 0.5 (8:00 clock time; prior to standardized breakfast), 0.75, 1, 1.5, 2, 2.5, 3.5, 4.5 hours on Day -1 (baseline), 0.5 (prior to standardized breakfast), 0.75, 1, 1.5, 2, 2.5, 3.5, 4.5 hours post study drug administration on Day 28 The area under the plasma glucose concentration time curve (GLU-AUC0:30-4:30h) was calculated using the linear trapezoidal rule from time of breakfast start (30 minutes after study drug administration \[time: 0.5 hours\] on Day 28) to 4 hours after breakfast start (time: 4.5 hours) and corrected by subtracting pre-breakfast plasma glucose concentration (time: 0.5 hours). GLU-AUC0:30-4:30h on Day -1 was the baseline. Change in GLU-AUC0:30-4:30h = GLU-AUC0:30-4:30h on Day 28 minus GLU-AUC0:30-4:30h on Day -1.

Insulin AUC0:30-4:30h on Day -1 was the baseline. Change in insulin AUC0:30-4:30h = insulin AUC0:30-4:30h on Day 28 minus insulin AUC0:30-4:30h on Day -1.
