Study Overview
Brief Summary
This is a study to compare AZD4831 pharmacokinetic (PK) parameters between participants with severe renal impairment and matched healthy volunteers following a single dose administration.
Detailed Description
All participants will receive a single oral dose of AZD4831 under fasted conditions and will be involved in the study approximately 2 weeks after dosing and up to approximately 38 days from screening.
Approximately 10 participants will be enrolled into each of the 2 cohorts parallelly and receive the study intervention to achieve 8 evaluable participants in each cohort.
- Cohort 1: 10 participants with severe renal impairment (Estimated glomerular filtration rate [eGFR] of ≥15 to <30 mL/min/1.73m^2)
- Cohort 2: 10 matched healthy volunteers with normal renal function (eGFR of ≥90 mL/min/1.73m^2).
The study will comprise of the following study periods:
- Screening period (21 days): participants will be screened for eligibility.
- Treatment period (3 days): participants will be admitted to the study centre in the evening of (Day -1) the day before administration of a single oral dose of AZD4831 (Day 1), and will be discharged after at least 24 h post-dose (Day 2).
- Follow-up period (13±2 days): participants will attend 5 visits at the study centre for PK sampling and safety assessments on Days 3, 5, 8, 11 and 15.
