What this trial studies

This observational study aims to evaluate the real-world effectiveness of mavacamten in patients diagnosed with obstructive hypertrophic cardiomyopathy (oHCM) in Canada. It involves a retrospective survey of physicians to gather data on patients who have started treatment with mavacamten through the Bristol Myers Squibb CAMZYOS Patient Support Program. The study focuses on adult patients with symptomatic oHCM classified as NYHA class II to III. By analyzing this data, the study seeks to provide insights into the treatment's effectiveness in a real-world setting.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 and older who have been diagnosed with symptomatic oHCM and have initiated treatment with mavacamten.

Not a fit: Patients who have received any cardiac myosin inhibitor in the six weeks prior to starting mavacamten will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide valuable information on the effectiveness of mavacamten, potentially improving treatment strategies for patients with oHCM.

How similar studies have performed: While this study focuses on real-world effectiveness, similar studies evaluating the effectiveness of mavacamten have shown promising results, indicating a potential for success.
