Arms Assigned Interventions
Experimental: Metformin + liraglutide 1.8 mg Drug: liraglutide
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).
Active Comparator: Metformin + lixisenatide 20 microg Drug: lixisenatide
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.
