Description as written by the study sponsor.

This study will compare the new medicine IcoSema, which is a combination of insulin icodec and semaglutide, taken once a week, to insulin icodec taken once a week in people with type 2 diabetes. The study will look at how well IcoSema controls blood sugar level in people with type 2 diabetes compared to insulin icodec. Participants will either get IcoSema or insulin icodec. Which treatment participants get is decided by chance. IcoSema and insulin icodec are both new medicines that doctors cannot prescribe.

The study will last for about 1 year and 1 month. Participants will have 21 clinic visits, 31 phone/video calls with the study doctor, and 4 contacts with the site that can either be clinic visits or phone/video calls At 11 clinic visits participants will have blood samples taken. At 7 clinic visits participants cannot eat or drink (except for water) for 8 hours before the visit.
