Study summary

This study compares insulin icodec (a new insulin taken once a week) to insulin degludec (an insulin taken once daily which is already available on the market) in people with type 2 diabetes.

The study will look at how well insulin icodec taken weekly controls blood sugar compared to insulin degludec taken daily.

Participants will get their study medicine in an injection pen. Participants will get a pen for weekly injection and one for daily injection. One will be icodec or degludec and the other will be dummy medicine. The treatment participants get is decided by chance. Participants and the study staff will not know which active medicine they get.

The insulin is injected with a needle in a skin fold in the thigh. The study could last for about 8 months. Participants will have 13 clinic visits and 17 phone calls with the study doctor. At 8 clinic visits participants will have blood samples taken. At 4 clinic visits participants cannot eat or drink (except for water) for 8 hours before the visit.

Women cannot take part if pregnant, breast-feeding or plan to become pregnant during the study period.
