study to assess the pharmacokinetics and safety of azd9977 in participants with renal impairment

Conditions: Renal Impairment

Summary: this is a single dose, non-randomized, open-label, parallel group study. the study will be conducted in participants with severe renal impairment and compared with matched participants with normal renal function. the duration of the study for an individual participant from screening to follow-up will be approximately 5 weeks.

the study will have 4 cohorts, consisting of participants with severe renal impairment who are not on dialysis (cohort 1), moderate renal impairment (cohort 2), mild renal impairment (cohort 3) and participants with normal renal function (cohort 4). following completion of cohort 1 and cohort 4, pharmacokinetics (pk) and safety data will be reviewed and a decision will be made whether to study unmatched participants with moderate and mild renal impairment (cohorts 2 and 3, respectively). participants will be screened up to 21 days before administration of study drug. eligible participants will be admitted to the clinical unit either on the evening of day -2 or on the morning of day -1. each participant will receive a single oral dose of the study drug under fasted conditions on day 1. participants will be required to remain resident in the clinical unit until the morning of day 3 but, if participants prefer, may also remain resident until all pk and other study procedures are completed on day 7. this decision to extend residency will be made at the discretion of the principal investigator. if participants do check out on day 3, participants will then return to the unit, as scheduled, for collection of pk samples and safety assessments, with a final follow-up visit on day 14.
