Study Summary

This study compares the effect of two doses of semaglutide (1.0 mg and 2.0 mg) in people with type 2 diabetes (T2D). People taking part in the study will take the medicine together with their current diabetes medicine (sulphonylurea and/or metformin). Participants will get a dose of either 1.0 mg or 2.0 mg semaglutide once a week - which dose is decided by chance. Participants will inject semaglutide under the skin once a week. The study will last for about 49 weeks. Participants will have 9 clinic visits and 2 phone calls with the study doctor. At the visits participants will have blood taken and eye tests done. Women cannot take part if pregnant, breast-feeding or planning to become pregnant during the study period. Female participants who can get pregnant will be checked 11 times for pregnancy via urine tests.
