Brief summary

This trial is conducted in Europe. The aim of the trial is to investigate the efficacy and safety of liraglutide versus lixisenatide as add-on to metformin in subjects with type 2 diabetes (T2DM).

Interventions

DRUGliraglutide

Starting dose of 0.6 mg/day, with weekly dose escalations of 0.6 mg/day until the maintenance dose of 1.8 mg/day is reached. Administered s.c. (subcutaneously, under the skin) once daily in addition to the subject's stable pre-trial metformin (equal to or above 1000 mg/day and up to 3000 mg/day).

Starting dose of 10 microg to be administered s.c. once daily, within the hour prior to the first meal of the day or the evening meal in addition to subject's stable pre-trial metformin (equal to or above 1000mg/day and up to 3000mg/day). Dose escalation to 20 microg s.c. once daily from day 15 after randomization.

Outcome results

Primary

Change in Glycosylated Haemoglobin (HbA1c) From Baseline

Change from baseline in HbA1c after 26 weeks of treatment.

Time frame: Week 0, week 26

Population: The full analysis set (FAS) included all randomised subjects. Missing values were imputed using predicted values from the mixed model for repeated measurements (MMRM) model. Due to missing HbA1c post baseline data, 194 and 191 subjects in liraglutide and lixisenatide treatment group, respectively were included in the HbA1c analysis.
