A Study to Look at How Safe NNC0472-0147 is in Healthy People and in People With Type 2 Diabetes

This study is investigating the safety and tolerability of the new medicine NNC0472-0147, its concentrations in the blood and its effect on blood sugar for the treatment of diabetes. Another goal of the study is to determine an effect of NNC0472-0147 on cholesterol. The first part of the study is conducted in healthy people, while the second part involves people with type 2 diabetes (T2DM). The study will test how NNC0472-0147 is tolerated by the body, how it is taken up in the blood, how long it stays there and how much blood sugar is lowered. In part 1, participants will either get the new medicine NNC0472-0147 or placebo (an injection that does not contain active medicine) - which treatment is decided by chance. In part 2, participants will either get the new medicine NNC0472-0147 or insulin glargine - which treatment is decided by chance. It is the first time that NNC0472-0147 is tested in humans. Participants will get once daily injections of either NNC0472-0147 or insulin glargine for a treatment period of fourteen days. The injections will be given under the skin (subcutaneously, s.c.) of the left thigh. Participants will be in the study for about 7 weeks. There will be 15 visits with the study doctor. People cannot be in the study if the study doctor thinks that there are risks for their health. Only women who cannot become pregnant are allowed to participate.
