Semaglutide Cardiovascular Outcomes Trial in Patients With Type 2 Diabetes

The researchers are doing this study to look whether the type 2 diabetes medicine, semaglutide, has a positive effect on heart disease. Participants will either get semaglutide tablets or placebo tablets ("dummy" medicine) - which treatment is decided by chance. Participants must take one tablet with water every morning on an empty stomach and not eat or drink anything for at least 30 minutes. The study will last for about 3.5-5 years. Participants will have up to 25 clinic visits and 1 phone call with the study doctor. Women cannot be in the study if pregnant, breast-feeding or if they plan to become pregnant during the study period.
