Is this trial a fit for you?

Likely a good fit

Patients in Japan with obstructive hypertrophic cardiomyopathy who initiate mavacamten for an approved indication at participating medical institutions during the enrollment period.

Probably not a fit

Patients receiving mavacamten for off-label indications, those with non-obstructive HCM, or patients not starting mavacamten will not be included and therefore will not directly benefit from this surveillance data.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is a post-marketing, observational surveillance program enrolling patients in Japan who start mavacamten for the approved indication. Data on real-world effectiveness and safety will be collected from participating medical institutions during the enrollment and follow-up periods. Patients receiving mavacamten for off-label indications will be excluded. The program is sponsored by Bristol-Myers Squibb with data coordination through CMIC Co., Ltd in Tokyo.

Why it matters

Potential benefit: If successful, this could provide practical information on how well mavacamten works and how safe it is for Japanese patients with obstructive HCM in routine clinical practice.

How similar studies have gone: Randomized trials such as EXPLORER-HCM and VALOR-HCM demonstrated clinical benefit of mavacamten for obstructive HCM, and this program seeks to confirm effectiveness and safety in real-world Japanese practice.
