LixiLan-O Phase III trial of insulin glargine + lixisenatide met endpoints in type 2 diabetes-Sanofi

Sanofi announced that the LixiLan-O Phase III clinical trial met its primary objective in patients with type 2 diabetes treated with metformin. The fixed-ratio combination of insulin glargine 100 units/mL (Lantus) and lixisenatide (Lyxumia), a GLP-1 RA, demonstrated statistically superior reduction in HbA1c (average blood glucose over the previous three months) compared with lixisenatide and compared with insulin glargine 100 units/mL. Overall, the fixed-ratio combination had a safety profile reflecting those of lixisenatide and insulin glargine 100 units/mL.

The Phase III LixiLan clinical development program began in Q1 2014 and consists of the LixiLan-O and LixiLan-L trials. LixiLan-O investigated the efficacy and safety of a once-daily single injection of the fixed-ratio combination of insulin glargine 100 units/mL and lixisenatide versus treatment with either lixisenatide or insulin glargine 100 units/mL over a 30 week period in 1,170 patients whose type 2 diabetes was not adequately controlled on metformin alone or on metformin combined with a second oral anti-diabetic agent. Treatment with metformin was continued for all participants throughout the study. Full results will be communicated in an appropriate scientific forum.

The ongoing LixiLan-L study investigates the efficacy and safety of a once-daily single injection of the fixed-ratio combination of insulin glargine 100 units/mL and lixisenatide versus treatment with insulin glargine 100 units/mL over a 30-week period in 736 patients whose type 2 diabetes was not adequately controlled at screening on a basal insulin with or without oral anti-diabetic drugs. Only metformin, if taken, was continued throughout the study. The study will be completed in Q3 2015.
