Diabetes Mellitus, Type 2
Conditions
Brief 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.
Interventions
Semaglutide injected subcutaneously (s.c., under the skin) once-weekly. Participants will keep taking their pre-study diabetes tablets throughout the study.
Semaglutide placebo injected once-weekly from week 13 to week 40.
