Research Study to Investigate How a Study Medicine (NNC9204- 1177) Affects Blood Levels of Other Medicines in Healthy People

An Open-label, Single-sequence, Crossover Trial Investigating the Influence of NNC9204-1177 on Pharmacokinetics of Index Substrates for Cytochrome P450 Enzymes

The study looks at how the study medicine (NNC9204-1177) affects other medicines in the body. Participants will get the study medicine and 5 other medicines which have all been approved by the authorities. Participants will get 1 injection of the study medicine each week for 11 weeks. The study medicine is injected under the skin in the stomach area. All injections will be given by study staff. Participants will get 5 medicines as tablets, capsules or syrup to be taken with water at the beginning of the study and after 10 weeks of treatment with the study medicine. The study will last for about 4 months. Participants will have 14 visits to the clinic with the study staff and study doctor. Participants will have blood draws and 2 different kinds of electrocardiograms taken during the study. They will be asked about your mental health. People who use any medication, including herbal products, cannot take part in the study. Women cannot take part if pregnant, breast-feeding or planning to become pregnant during the study period or if they use birth control pills or other hormonal birth control products.
