The VALOR-HCM trial was a Phase 3 clinical trial which compared the Bristol Myers Squibb drug mavacamten (brand name Camzyos) to septal reduction therapy (myectomy and septal alcohol ablation) over a 16 week period. At the end of the 16 week period, the patients originally randomized to the placebo were prescribed mavacamten, while those originally prescribed mavacamten continued taking the drug for an additional 16 weeks for a total of 32 weeks
At last weekend’s American Heart Association meeting in Chicago and simultaneously published in Circulation, lead investigator Dr. Milind Desai of the Cleveland Clinic announced that after 32 weeks of mavacamten treatment, patients continued to see positive cardiac remodeling, as well as improvement to left ventricular outflow tract gradient, diastolic function and quality of life. This ultimately allowed a whopping 88% of patients enrolled in the trial to avoid a septal reduction procedure.
Similar results were noted in those patients who began mavacamten after an initial 16 weeks on a placebo.
This is good news for HCM patients!
The VALOR-HCM trial results have just been published in the Journal of the American College of Cardiology.
This study enrolled 112 obstructive HCM patients for a 16 week double blind trial of the drug mavacamten (brand name Camzyos). All patients in the trial had been referred for septal reduction therapy – either septal myectomy or septal alcohol ablation – to treat their highly symptomatic obstructive hypertrophic cardiomyopathy. The researchers looked at whether the addition of mavacamten to their other drugs would improve their symptoms enough so that they no longer met the criteria for septal reduction therapy (SRT) under the 2011 ACC/AHA Guidelines.

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.
