About

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.
