Liraglutide | ||||||||||||||||||||||||
Arm description |
Liraglutide was administered subcutaneously (s.c.; under the skin) once daily in addition to the subject's stable pre-trial metformin (maximum tolerated dose, equal to or above 1000 mg/day and up to 3000 mg/day) for a total duration of 26 weeks. Starting dose of liraglutide was 0.6 mg/day, with weekly dose escalations of 0.6 mg/day until the maintenance dose of 1.8 mg/day was reached. | ||||||||||||||||||||||||

Dosage and administration details |
Liraglutide was to be injected subcutaneously in the thigh, upper arm (deltoid region) or abdomen. The injection site did not have to be consistent throughout the trial. Injections could be done at any time of the day irrespective of meals. It was recommended that the time of injection was consistent throughout the trial. Subjects were instructed to perform an air shot before the first use of a new pre-filled pen. Subjects were to follow a dose escalation. Liraglutide was to be initiated with a starting dose of 0.6 mg/day, with subsequent weekly dose escalations of 0.6 mg/day in accordance with the approved dose escalation for liraglutide until the maintenance dose of 1.8 mg/day was reached. Escalation from 0.6 mg/day to 1.8 mg/day could be extended by 7 days if subjects did not tolerate an increase in dose during dose escalation according to the investigator’s opinion. The liraglutide dose of 1.8 mg/day was to remain unchanged throughout the remainder of the trial.

Dosage and administration details |
Lixisenatide was to be administered once daily, within the hour prior to the first meal of the day or the evening meal, in accordance with the approved SmPC (Summary of Product Characteristics) at the time of trial initiation and recruitment of subjects. Dose escalation for lixisenatide was according to the approved label. Following a starting dose of 10 μg, the dose was to be escalated to 20 μg from day 15 after randomisation. If a dose of lixisenatide was missed, it was to be injected within the hour prior to the next meal. Injections were to be done subcutaneously in the thigh, abdomen or upper arm. Trial drug medication with lixisenatide after dose escalation was to be continued at a fixed dose throughout the trial.
