Phase 1 PK Study to Evaluate the PK of CIN-107 in Subjects With Hepatic Impairment

Phase 1
Completed
Conditions
Hypertension
Interventions
Registration Number
NCT05961397
Lead Sponsor
AstraZeneca
Brief Summary

The goal of this Phase 1, open-label, single-dose, parallel-group study is to evaluate the pharmacokinetics (PK) of a single 10-mg oral dose of baxdrostat in subjects with varying degrees of hepatic function. The main objectives are to:

* To assess the safety and tolerability of baxdrostat following administration of a single oral dose of baxdrostat to subjects with varying degrees of hepatic function; and

* To characterize the PK of baxdrostat following administration of a single oral dose of baxdrostat to subjects with varying degrees of hepatic function.

Participants were administered a single 10-mg oral dose of baxdrostat in the fasted state the morning of Day 1. Plasma samples were drawn at various timepoints. Safety assessments included adverse events, vital signs, 12-lead electrocardiograms (ECGs), clinical laboratory evaluations, and physical examinations.

Twenty subjects in 2 groups based on the Child-Pugh classification in the protocol at screening: up to 10 subjects in the normal hepatic function group and up to 10 subjects in the moderate hepatic impairment group. Twenty subjects entered and completed the study.

Primary Outcome Measures
NameTimeMethod
Maximum Plasma Concentration [Cmax] of baxdrostat and the CIN-107-M metabolite following administration of a single oral dose of baxdrostat to subjects with varying degrees of hepatic function.up to 72 hours post-dose

Cmax will be determined for baxdrostat and the CIN-107M metabolite

Time to Maximum Plasma Concentration [Tmax] of baxdrostat and the CIN-107-M metabolite following administration of a single oral dose of baxdrostat to subjects with varying degrees of hepatic function.up to 72 hours post-dose

Tmax will be determined for baxdrostat and the CIN-107M metabolite

Area under the curve (AUC) for baxdrostat and the CIN-107-M metabolite following administration of a single oral dose of baxdrostat to subjects with varying degrees of hepatic functionup to 72 hours post-dose

Measurement of plasma concentrations of baxdrostat and its major metabolite CIN-107-M. AUC \[0 to 24 hours, 0 to last quantifiable concentration, and 0 to infinity of baxdrostat\] will be determined for baxdrostat and the CIN-107M metabolite.

Incidence of treatment emergent adverse events following administration of a single oral dose of baxdrostat to subjects with varying degrees of hepatic function.up to 72 hours post-dose

The safety and tolerability of baxdrostat was assessed throughout the study based on incidence of treatment emergent adverse events (AEs), following administration of a single oral dose of baxdrostat to subjects with varying degrees of hepatic function.

Terminal elimination half-life of baxdrostat and the CIN-107-M metabolite following administration of a single oral dose of baxdrostat to subjects with varying degrees of hepatic function.up to 72 hours post-dose

Terminal elimination half-life will be determined for baxdrostat and the CIN-107M metabolite
