研究概览
简要总结
This study will look at the change in participant's body weight from the start to the end of the study. This is to compare the effect on body weight in people taking semaglutide (a new medicine) and people taking "dummy" medicine. In addition to taking the medicine, the participant will have talks with study staff about healthy food choices, how to be more physically active and what a participant can do to lose weight.
The participant will get semaglutide for the first 20 weeks. Then the participant will get either semaglutide or "dummy" medicine - which treatment the participant gets after the 20 weeks is decided by chance. The participants will need to take 1 injection once a week. The study medicine is injected with a thin needle in a skin fold in the stomach, thigh or upper arm. The study will last for about 1.5 years.

研究组 & 干预措施
Semaglutide
Run-in Period: Participants will receive semaglutide at an escalating doses (0.25 mg, 0.5 mg, 1 mg, 1.7 mg, 2.4 mg) for 20 weeks (week 0 to week 20). The dose will be escalated to next level every 4 weeks.
Maintenance period: Participants will be randomized to receive semaglutide injection for 48 weeks (from week 20 to week 68).
The trial product will be administered as an adjunct to a reduced-calorie diet and increased physical activity during the trial period.
干预措施: Semaglutide (Drug)
Placebo
Run-in Period: Participants will receive semaglutide at an escalating doses (0.25 mg, 0.5 mg, 1 mg, 1.7 mg, 2.4 mg) for 20 weeks (week 0 to week 20). The dose will be escalated to next level every 4 weeks.
Maintenance period: Participants will be randomized to receive semaglutide placebo injection for 48 weeks (from week 20 to week 68).

结局指标
主要结局
Change From Randomisation to Week 68 in Body Weight (%)
时间窗: Randomisation (week 20) to week 68
Change in body weight from baseline (week 20) to week 68 is presented. The endpoint was evaluated based on the data from both in-trial and on-treatment observation periods. In-trial observation period: the uninterrupted time interval from start of run-in (week 0) to last trial-related subject-site contact (week 75). On-treatment observation period: includes all time intervals in which participants are considered to be on treatment from the first (week 0) to last trial product administration (week 68) including 2 weeks of follow-up. It excludes any period of temporary treatment interruption. Temporary treatment interruption is defined as more than 2 consecutive missed doses (off-treatment period).
