About this study

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

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.

Read the detailed 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)

Secondary outcomes (5)
  1. Number of Participants With Adverse Events

    Safety assessments will be performed by incidence of adverse events during the whole study at specified time points

    Measured: Up to 75 days

  2. Body Weight at Screening and EOS

    Safety assessments will be performed by vital signs during the whole study at screening, Day-1, Day 3 and at the EOS Visit. A complete physical examination includes assessments of general appearance, skin, head and neck, chest, abdomen, back, spine, extremity neurological, and mental systems. Brief physical examination means chest examinations.

    Height (cm) and body weight (kg) will be measured at screening, and BMI (kg/m2) will be calculated. Body weight (kg) will be measured at EOS. The mean weight and the standard deviation are analysis for different cohort.

    Measured: Body weight (kg) will be measured at screening (baseline) and EOS(75 days).

  3. Physical Examination Findings

    Safety assessments will be performed by physical examination findings during the whole study at specified time points

    Measured: Up to 75 days

  4. Heart Rate at Baseline and Day 75

    Safety assessments will be performed by electrocardiogram (ECG) parameters findings during the whole study at specified time points

    Measured: Up to 75 days

  5. Clinical Laboratory Tests Data

    Safety assessments will be performed by clinical laboratory tests data(including hematology and blood chemistry, coagulation and urinalysis parameters) during the whole study at specified time points

    Measured: Up to 75 days

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Mavacamten in people with Hypertrophic Cardiomyopathy, run by LianBio LLC at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 13 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 25 Jul 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 25 Jul 2024). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Area Under the Curve (AUC) (0-last), AUC(0-inf) (time frame: Predose, Day 1, Day 7, Day 10, Day 14, Day 21, Day 28, Day 35, Day 45, Day 67 and Day 75 post-dose). The study lists 6 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05135871, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 25 Jul 2024.
