Abstract: Methods for treating obstructive hypertrophic cardiomyopathy are described herein. The treatment methods include the administration of a cardiac myosin inhibitor (CK-3773274, also referred to as CK-274 or aficamten) and may include titrating an administrated daily dose based on one or more components of an echocardiogram. The daily dose may be increased, maintained, decreased, or terminated, based on the echocardiogram.

Abstract: Provided herein are methods of treating patients by administering aficamten, or a pharmaceutically acceptable salt thereof, including in combination with beta blockers. The treatment methods include improving heart rate reserve, peak metabolic equivalents (METs), exercise duration, peak oxygen uptake (pVO2) as well as other parameters related to exercise capacity.

Abstract: Methods for treating symptomatic obstructive hypertrophic cardiomyopathy (oHCM) are described herein. The treatment methods include the administration of a cardiac myosin inhibitor (CK-3773274, also referred to as CK-274 or aficamten) and may include titrating an administrated daily dose based on one or more components of an echocardiogram. The daily dose may be increased, maintained, decreased, or terminated, based on the echocardiogram. The methods may be useful for treating patients who have been recently diagnosed with oHCM, patients who are treatment naïve for oHCM, or patients who have previously received SOC medical therapy for oHCM and have discontinued said therapy prior to administration of aficamten, such as patients with chronic oHCM.

Abstract: Methods for treating non-obstructive hypertrophic cardiomyopathy or hypertrophic cardiomyopathy with mid-ventricular obstruction (MVO) are described herein. The treatment methods include the administration of a cardiac myosin inhibitor (CK-3773274, also referred to as CK-274 or aficamten) and may include titrating an administrated daily dose based on a component of an echocardiogram. The daily dose may be increased, maintained, or decreased, or terminated, based on the echocardiogram.
