Is this trial a fit for you?

Likely a good fit

Ideal candidates include adults aged 18 and older diagnosed with symptomatic obstructive HCM according to established guidelines.

Probably not a fit

Patients with non-obstructive forms of hypertrophic cardiomyopathy or those who do not meet the eligibility criteria may not benefit from this study.

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

What this trial studies

This registry evaluates the characteristics, treatment patterns, and outcomes of patients with symptomatic obstructive hypertrophic cardiomyopathy (oHCM) in the United States and Europe. It focuses on those receiving mavacamten, other treatments, or no treatment due to intolerance or prior treatment failure. The study aims to gather real-world data on the safety and effectiveness of mavacamten in this patient population.

Why it matters

Potential benefit: If successful, this study could provide valuable insights into the real-world effectiveness and safety of mavacamten for patients with obstructive hypertrophic cardiomyopathy.

How similar studies have gone: Other studies have shown promise in evaluating treatments for obstructive HCM, but this registry approach is relatively novel in its comprehensive real-world assessment.

Inclusion Criteria

* ≥ 18 years of age at the time of informed consent.
* Willing and able to provide written informed consent form (ICF) and any required privacy authorization prior to the initiation of study procedures (or in those situations where consent cannot be given by participants, consent provided by their legally acceptable representatives)

United States Sub-Study

* Diagnosis of obstructive HCM consistent with 2020 American Heart Association/American College of Cardiology (AHA/ACC) guidelines.

  * Obstructive HCM is defined clinically by the presence of increased LV wall thickness ≥ 15 mm (or ≥ 13 mm with positive family history of HCM) in a nondilated ventricular chamber that is not solely explained by abnormal loading conditions (eg, another cardiac or systemic disease) and peak LVOT gradient of ≥ 30 mmHg at rest or with provocation.
* Has documented LVEF of ≥ 55% recorded by echocardiography within the last 6 months.
* Symptoms consistent with NYHA functional class II-IV.
* Receiving beta blocker (BB)s, non-dihydropyridine calcium. channel blockers (nonDHP CCBs), disopyramide, and/or mavacamten (once available) as part of routine clinical care; or currently receiving no treatment due to intolerance or failure of prior treatment (eg, BBs, non-DHP CCBs, or disopyramide) for obstructive HCM.

European Sub-study

* Diagnosis of obstructive HCM consistent with the most recent European Society of Cardiology (ESC) and American Heart Association/American College of Cardiology (AHA/ACC) guidelines
* Documented LVEF of ≥55% recorded by TTE
* Documented symptoms consistent with NYHA functional class II-III at enrollment or within 6 months prior to enrollment (if not available at enrollment).
* As part of routine clinical care for obstructive HCM: receiving BBs, non-DHP CCBs, disopyramide; initiating mavacamten at enrollment; or currently receiving no treatment due to intolerance or failure of prior treatment (e.g., BBs, non-DHP CCBs, or disopyramide).

Exclusion Criteria

* Known phenocopy disease (e.g., Fabry disease, amyloidosis) or LV hypertrophy associated with hypertension.
* Documentation of any fixed obstruction of the outflow tract such as aortic valve stenosis or replacement.
* Prior treatment of obstructive HCM with invasive septal reduction (surgical myectomy or percutaneous alcohol septal ablation \[ASA\]) within 6 months prior to enrollment; participants with an unsuccessful myectomy or percutaneous ASA performed \> 6 months prior to enrollment may be enrolled.
* Naïve to treatment for obstructive HCM (ie, never treated with BBs, nonDHP CCBs, or disopyramide).

United States Sub-Study

* Receiving an investigational therapeutic agent for obstructive HCM (eg, myosin-inhibitors other than mavacamten) in an interventional clinical trial at participant enrollment.
* Previously or currently enrolled in a long-term safety extension study of mavacamten (eg, EXPLORER-HCM \[ClinicalTrials.gov, NCT03470545\], MAVA-LTE \[NCT03723655\], PIONEER-OLE \[NCT03496168\], VALORHCM \[NCT04349072\], or MAVERICK \[NCT03442764\])

European Sub-study

* Receiving an investigational therapeutic agent or any cardiac myosin inhibitor and/or modulators for obstructive HCM at patient enrolment
* Previously or currently enrolled in other HCM registry studies (e.g., TORCH, REMY, EU-PASS)
* Previously or currently enrolled in a study of mavacamten (e.g., EXPLORER-HCM \[ClinicalTrials.gov, NCT03470545\], MAVA-LTE \[NCT03723655\], PIONEER-OLE \[NCT03496168\], VALOR-HCM \[NCT04349072\], MAVERICK \[NCT03442764\], or MEMENTO \[NCT2264899\])
* Previously treated with mavacamten
