Interventions

  • Semaglutide — DRUG
    Semaglutide injections will be administered once-weekly by a pre-filled pen-injector at the same day of the week (to the extent possible). Injections may be administered in the thigh, abdomen or upper arm, at any time of day irrespective of meals.
  • Placebo (semaglutide) — DRUG
    Placebo (semaglutide) injections will be administered once-weekly by a pre-filled pen-injector at the same day of the week (to the extent possible). Injections may be administered in the thigh, abdomen or upper arm, at any time of day irrespective of meals.

Study Details

This study will look at the change in participants' 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, participants will have talks with study staff about healthy food choices, how to be more physically active and what participants can do to lose weight. Participants will either get semaglutide or "dummy" medicine - which treatment participants get is decided by chance. Participants are three times as likely to get semaglutide as "dummy" medicine. Participants will need to take 1 injection once a week. The study medicine is injected with a thin needle in a skinfold in the stomach, thigh or upper arm. The study will last for about one and a half years. Participants will have 14 clinic visits and 11 phone calls with the study doctor.

Arms

  • Experimental: Semaglutide 2.4 mg
    Participants will receive semaglutide injections once-weekly for 68 weeks. Participants will be initiated at a once-weekly dose of 0.25 mg and follow a fixed-dose escalation regimen, with dose increases every 4 weeks (to doses of 0.5, 1.0, 1.7 and 2.4 mg/week), until the target dose (2.4 mg) is reached after 16 weeks. Participants will continue semaglutide 2.4 mg until week 68.
  • Placebo Comparator: Placebo (semaglutide 2.4 mg)
    Participants will receive placebo (semaglutide) injections once-weekly for 68 weeks. Participants will be initiated at a once-weekly dose of 0.25 mg and follow a fixed-dose escalation regimen, with dose increases every 4 weeks (to doses of 0.5, 1.0, 1.7 and 2.4 mg/week), until the target dose (2.4 mg) is reached after 16 weeks. Participants will continue placebo (semaglutide 2.4 mg) until week 68.
  • Experimental: Semaglutide 1.7 mg
    Participants will receive semaglutide injections once-weekly for 68 weeks. Participants will be initiated at a once-weekly dose of 0.25 mg and follow a fixed-dose escalation regimen, with dose increases every 4 weeks (to doses of 0.5, 1.0 and 1.7 mg/week), until the target dose (1.7 mg) is reached after 12 weeks. Participants will continue semaglutide 1.7 mg until week 68.
  • Placebo Comparator: Placebo (semaglutide 1.7 mg)
    Participants will receive placebo (semaglutide) injections once-weekly for 68 weeks. Participants will be initiated at a once-weekly dose of 0.25 mg and follow a fixed-dose escalation regimen, with dose increases every 4 weeks (to doses of 0.5, 1.0 and 1.7 mg/week), until the target dose (1.7 mg) is reached after 12 weeks. Participants will continue placebo (semaglutide 1.7) until week 68.
