In addition to the presentation of the results of the VALOR-HCM study which compared mavacamten to septal reduction techniques, covered here in its own HCMBeat blog entry, ACC 2022 featured two other presentations about the new class of drugs known as myosin inhibitors, such as Bristol Myers Squibb’s mavacamten and Cytokinetics’ aficamten.
The Phase 3 VALOR-HCM trial results were presented this morning at the American College of Cardiology annual meeting in Washington, DC by the principal investigator, Dr. Milind Desai of the Cleveland Clinic, and the results are good!
What was the VALOR-HCM study?
15 – 20 million people worldwide are estimated to have HCM, with 2/3 of this group having the obstructive form which can cause severe symptoms. Historically, these patients have been treated with medications approved for other conditions, and if those don’t relieve symptoms, they are referred on for septal reduction therapies (SRT) like alcohol septal ablation (a catheter based procedure) or septal myectomy (open heart surgery), which are invasive therapies requiring specialized care and which are not widely available.
The VALOR study was designed to compare mavacamten head to head with SRT to see if mavacamten could be a non-invasive treatment alternative for obstructive HCM.
The July edition of the the American College of Cardiology’s magazine features a cover story about HCM.
The article surveys the history of HCM and then moves through the evolution into contemporary treatments. The article also contains a summary of important topics from the new 2020 AHA/ACC Guidelines and highlights EXPLORER-HCM, the recent groundbreaking clinical trial of mavacamten.
