Study Evaluating the Pharmacokinetics of Mavacamten in Healthy Adult Chinese Subjects

Hypertrophic Cardiomyopathy Clinical Trial

Official title: An Open-Label, Parallel-Group, Single-Center Phase 1 Clinical Study to Evaluate the Pharmacokinetics of a Single Oral Dose of Mavacamten in Healthy Adult Chinese Subjects

Status Completed

Clinical Trial Summary

Mavacamten is a small-molecule allosteric inhibitor of cardiac myosin that reversibly inhibits its binding to cardiac actin, thereby relieving systolic hypercontractility and improving ventricular compliance. This is an open-label, parallel-group, single-center Phase 1 clinical study. Healthy adult Chinese subjects with different genotypes will be included and administered with a single fasted oral dose of mavacamten to evaluate its PK profile. Up to 44 subjects will be enrolled in this study.

Clinical Trial Description

Approximately 44 healthy adult Chinese subjects are expected to be enrolled in this study according to their genotypes into 4 cohorts. The doses administered include: 15 mg for cohort 1; 25 mg for Cohort 2; 15 mg for Cohort 3; 15 mg for Cohort 4. Blood samples will be collected from subjects at scheduled time points for PK testing. Series of safety assessments (including but not limited to AEs, laboratory tests, vital signs, and ECGs) will be performed during the whole study at specified time points. This study will consist of the following 5 periods: - Pre-screening period and Screening period (Day -43 to Day -2, up to 42 days) - In-house period (Day -1 to Day 3, total 4 days) - Outpatient period (Day 4 to Day 75, total 72 days): - End of study visit (Day 75) ;
