Effect of Mavacamten Treatment on Coronary Flow Reserve in oHCM
(MavaPET)
What this study is about
The goal of this observational study is to measure the effect of mavacamten treatment on blood flow in the heart muscle (myocardium) in patients with obstructive hypertrophic cardiomyopathy. The main question it aims to answer is: • Does mavacamten treatment improve blood flow in the heart muscle? Participants will take mavacamten at the direction of their treating physician.
View original scientific description
The goal of this observational study is to measure the effect of mavacamten treatment on blood flow in the heart muscle (myocardium) in patients with obstructive hypertrophic cardiomyopathy. The main question it aims to answer is: • Does mavacamten treatment improve blood flow in the heart muscle? Participants will take mavacamten at the direction of their treating physician. Participants will complete 2 myocardial Positron Emission Tomography and Computed Tomography (PET-CT) scans. The first scan will be completed before participants start taking mavacamten. The scan will be repeated after 12 months of mavacamten treatment.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Willingness and ability to provide written informed consent
- Willingness and ability to comply with scheduled visits and study procedures
- Male or female, aged 18-85 years
- Diagnosed with obstructive hypertrophic cardiomyopathy according to presence of a left ventricular wall thickness of ≥15 mm that is otherwise unexplained by abnormal loading conditions (e.g., hypertension, valvular, congenital disease) or infiltrative cardiomyopathies. Unexplained left ventricular wall thickness of ≥13 mm is sufficient for diagnosis in relatives of individuals with hypertrophic cardiomyopathy or those who are genotype positive.
- Has been prescribed mavacamten consistent with US Prescribing Information
- Ability and intention to adhere to oral mavacamten therapy as prescribed by treating physician for the duration of study participation
- For females of reproductive potential: negative pregnancy test at screening/baseline and 12 month visits.
Exclusion criteria
- Pregnancy or lactation
- Known hypersensitivity to components of mavacamten or regadenoson
- Prior treatment with mavacamten or aficamten 11\. Over weight limit for imaging gantry. 12. To minimize the risk of participants undergoing PET/CT with inadequate image quality, participants with left ventricular systolic dysfunction or lung disease will be excluded.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
