This study looks at how well a new medicine, called semaglutide, works at helping people with obesity and prediabetes. This study will look at how much weight participants lose, and if participants can go from having blood sugar that is higher than normal (prediabetes) to having normal blood sugar. Semaglutide is compared to a "dummy" medicine. The "dummy" medicine looks like semaglutide but has no effect on the body. 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 they get is decided by chance. Participants are 2 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 skin fold in the stomach, thigh or upper arm. The study will last for about 19 months. Participants have to take the study medicine every week for the first 12 months. The last 7 months participants will not take any medication. Participants will have 14 clinic visits and 1 phone call with the study staff. At 9 of the clinic visits Participants will have blood samples taken. Women cannot take part if pregnant, breast-feeding or plan to become pregnant during the study period.

Change in Body Weight (Percentage [%])
Change in body weight from randomisation (week 0) to end of treatment (week 52) is presented. The endpoint was evaluated based on the data from in-trial observation period which was defined as the time period where the participant was assessed in the main phase of the study. The 'in-trial' (main phase) observation period for a participant begins on the date of randomisation and ends at the first of the following dates (both inclusive): safety visit, withdrawal of consent, last contact with participant (for participants lost to follow-up), death.
Time frame: From randomisation (week 0) to end of treatment (week 52)
Participants With Change to Normoglycemia
