A Research Study Looking at How a Single Dose of the Medicine Cagrilintide Behaves in Participants With Reduced Liver Function and in Healthy Participants With Normal Liver Function

A Study Investigating the Pharmacokinetic Properties of Cagrilintide in Participants With Various Degrees of Hepatic Impairment

Cagrilintide is under development for weight management. In the development of cagrilintide, it is important to see if liver function influences how the body absorbs, breaks down, and eliminates cagrilintide. This will be tested in this study by comparing the blood levels of cagrilintide in people with reduced liver function to those of people with normal liver function. Cagrilintide is a long-acting study medicine that resembles one of the body's own hormones called amylin that is involved in regulation of food intake and body weight. It is the hope that cagrilintide can help participants with weight management. Both the participant and the study doctor will know what treatment is being provided to the participant. All participants will receive a single dose of 0.9 milligrams (mg)cagrilintide. The study medicine will be given in the form of an injection in a skinfold of the belly (subcutaneous). The study will last up to 10 weeks. If participants are eligible for this study, they will come to the clinic a total of 7 times and stay in the clinic for 7 days (6 nights). Women cannot take part if pregnant, breast-feeding or plan to get pregnant during the study period. Women who are able to become pregnant must use highly effective contraception and will be counselled on the use of contraception.

Participants with normal hepatic function will receive a single subcutaneous (s.c.) dose of 0.9 milligrams (mg) of cagrilintide on Day 1.

Participants with mild hepatic impairment (Child Pugh Grade A) will receive a single subcutaneous (s.c.) dose of 0.9 milligrams (mg) of cagrilintide on Day 1.

Participants with moderate hepatic impairment (Child-Pugh Grade B) will receive a single subcutaneous (s.c.) dose of 0.9 milligrams (mg) of cagrilintide on Day 1.

Participants with severe hepatic impairment (Child-Pugh Grade C) will receive a single subcutaneous (s.c.) dose of 0.9 milligrams (mg) of cagrilintide on Day 1

Cagrilintide will be administered subcutaneously in the abdomen in the form of a solution for injection.
