Gene secrets could explain why heart drug works for some, not others
NCT ID NCT07408427
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study aims to find out why the heart medication mavacamten works better for some people with hypertrophic cardiomyopathy (a condition where the heart muscle is too thick) than for others. Researchers will look at participants' genes, including the specific gene causing their condition and a gene called CYP2C19 that affects how the body processes drugs. The goal is to predict who will benefit most from the medication, leading to more personalized treatment. About 140 adults with this condition will take part.

Who is studied
The study will enroll adult patients with a diagnosis of symptomatic obstructive hypertrophic cardiomyopathy (oHCM). The target population consists of individuals who are either currently receiving mavacamten as part of their standard clinical care or are candidates for initiating therapy. Participants will be recruited from the specialist Inherited Cardiac Conditions (ICC) clinic at the study site.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Participants above the age of 18 years, with a confirmed diagnosis of oHCM, not solely explained by abnormal loading conditions (e.g. significant hypertension, valvular disease). Exclusion Criteria: * HCM phenocopies (e.g., amyloid, Fabry's disease) * Prior septal reduction therapy (within 6 months) * Contraindications to mavacamten (e.g., baseline LVEF \< 55%, pregnancy, uncontrolled heart failure)
