Pharmacokinetics of Petrelintide in Participants With Impaired Hepatic Function

This is a Phase 1, open-label, multicenter, single-dose, parallel-group, non-randomized trial to evaluate the PK, safety, and tolerability of petrelintide after a single dose in participants with mild, moderate, or severe HI, and participants with normal hepatic function. Allocation of participants to the hepatic function groups will be based on Child-Pugh classification.

Each participant will receive a single subcutaneous (SC) dose of petrelintide on Day 1.

Up to 18 participants with normal hepatic function and 18 participants with HI (6 participants each in the following groups: mild, moderate, or severe HI) will participate in this trial.

Inclusion criteria

All participants:

• Sex: male and female participants.
• Body mass index (BMI): 18.5 to 40.0 kg/m^2, inclusive, at screening.

Additional Inclusion Criteria for Participants with Normal Hepatic Function

• Participants who are considered healthy as determined by medical history, physical examination, and other screening procedures, with clinically normal hepatic function at screening..
• Clinical laboratory test results within normal reference range for the population, or results with acceptable deviations that are judged not to be clinically significant by the Investigator.

Additional Inclusion Criteria for Participants with Hepatic Impairment

• Participants with stable HI for at least 3 months, classified as Child-Pugh Grade A, B, or C as assessed by the Investigator.
• Participants should be otherwise judged to be in acceptable health (type 2 diabetes mellitus [T2DM] is allowed) in the opinion of the Investigator based on a medical evaluation (including a physical examination, medical history, electrocardiogram [ECG], vital signs, concomitant medication and the results of laboratory safety tests) performed during the screening visit.
• Participants with T2DM may be enrolled if they have/are: a. Hemoglobin A1c ≤11% at screening b. On a stable regimen for at least 8 weeks prior to screening, defined as: stable diet and exercise program, and/or, stable dose of metformin, and/or, stable dose of a sodium-glucose cotransporter-2 inhibitor.

Exclusion criteria

All participants:

• Known or suspected hypersensitivity to the IMP or related products.
• Female who is pregnant, breast-feeding or intends to become pregnant or is of child-bearing potential and not using a highly effective contraceptive method.
