What to Expect as a Participant

You will actively receive the study intervention — which may be a drug, biologic, device, or procedure.

Phase 1 is the earliest stage of human testing — safety and dosage are the primary focus. Visits are frequent and medical supervision is intensive. You will be among the first people to receive this treatment.

This trial targets 28 participants in total. It began in 2026-03-20 with a primary completion date of 2027-02-04.

Brief Summary

The purpose of this study is to examine the safety and tolerability of AZD6234 and AZD9550 in participants with hepatic impairment and participants with normal hepatic function.

Eligibility Criteria

Inclusion Criteria 1. Age 18-85 years at consent. 2.

Exposure to a new chemical entity within 30 days or 5 half lives (whichever longer) before intervention; prior exposure to AZD9550 or AZD6234; Prior/concomitant therapy: Healthy controls: 29. use of prescription/non prescription/supplements within 7 days (or 14 days for enzyme inducers) or 5 half lives before intervention unless judged non interfering; current oral contraceptives or oestrogen HRT. Hepatically impaired: 30. prohibited-weight loss medicines (including GLP 1), agents causing significant weight gain (e.g., systemic glucocorticoids, antipsychotics), GLP 1 RAs for diabetes, QT prolonging/prokinetic agents, oral contraceptives for contraception; restricted-short systemic glucocorticoids (≤7 days), 5HT 3 antiemetics at lowest effective dose, combined oral contraceptives for non contraceptive indications.
