Subjects on semaglutide followed a fixed dose-escalation. The maintenance dose of 0.5 mg was to be reached after 4 doses (4 weeks) of 0.25 mg semaglutide. Doses could not be changed during the trial after the maintenance dose had been reached. One test pen was to be supplied per subject at the screening visit in order to ensure the subject's willingness and ability to self-inject. The test pen contained semaglutide placebo, solution for injection, 1.5 mL prefilled PDS290 pen-injector and was to be administered once. The PDS290 pen-injector for semaglutide is a prefilled pen integrated with a 1.5 mL cartridge containing semaglutide 1.34 mg/mL and is designed to be used with NovoFine®, NovoFine® Plus and NovoTwist® disposable needles. Once weekly (same day of the week) administered by s.c. injection in thigh, abdomen or upper arm, at any time of the day.

Subjects randomised to semaglutide followed a fixed dose-escalation regimen. The maintenance dose of 1.0 mg was to be reached after 4 doses (4 weeks) of 0.25 mg, followed by 4 doses (4 weeks) of 0.5 mg semaglutide. Doses could not be changed during the trial after the maintenance dose had been reached. One test pen was to be supplied per subject at the screening visit in order to ensure the subject's willingness and ability to self-inject.

Once weekly (same day of the week) administered by s.c. injection in thigh, abdomen or upper arm, at any time of the day.

Subjects on insulin glargine were to start on 10 IU s.c. injected OD. The insulin dose adjustment had to aim to reach a pre-breakfast FPG of 4.0 to <5.5 mmol/L (71- <100 mg/dL). Once daily solution for injection in a 3 mL pre-filled SoloStar® pen to be administered in the thigh, abdomen or upper arm, at any time of the day

The post baseline responses were analysed using a mixed model for repeated measurements with treatment , country and stratum as fixed factors and baseline value as covariate, all nested within visit.

Non-inferiority was concluded if the upper limit of the two-sided 95% confidence interval for the estimated treatment difference between semaglutide 1.0 mg and insulin glargine was below the pre-specified non-inferiority margin (0.3 %).
