This clinical trial is focused on studying a heart condition known as Hypertrophic Cardiomyopathy, which is characterized by the thickening of the heart muscle. Specifically, the study looks at cases where this thickening leads to a blockage in the heart’s blood flow, known as Left Ventricular Outflow Tract Obstruction. The treatment being tested is a medication called MYK-224, which is taken in tablet form. The purpose of the study is to evaluate the safety and how well patients tolerate this medication.
Participants in the study will receive multiple doses of MYK-224 over a period of time. The study will monitor how the body processes the medication and its effects on the heart condition. Participants will be observed for any side effects and changes in their heart function. The study is designed to gather information on how effective the medication is in treating the symptoms of Hypertrophic Cardiomyopathy and improving the heart’s ability to pump blood.
The study is divided into two parts. In the first part, participants will receive the medication and be closely monitored. Those who complete the first part may have the option to continue into the second part, which is an extended study lasting up to two years. Throughout the study, participants will undergo regular check-ups, including heart function tests, to ensure their safety and to collect data on the medication’s effects.
