Is Aficamten the Blockbuster Drug Cytokinetics is Hoping For?

Published on by hcmbeatLeave a comment

Cytokinetics today released positive results from Sequoia-HCM, its Phase 3 clinical trial of the experimental drug aficamten in patients with symptomatic obstructive hypertrophic cardiomyopathy (HCM).  Patients treated with aficamten showed significantly increased exercise capacity as demonstrated by a 1.74 point increase in peak oxygen uptake (pVO2) measured during cardiopulmonary exercise testing.  Improvements were also seen in provoked outflow tract gradients, and most importantly, patients felt better.  

The study had enrollment of approximately 300 patients who were followed for 24 weeks. 

Aficamten was well-tolerated, adverse events were comparable to those taking a placebo, and importantly, there were no instances of worsening heart failure or treatment interruptions due to low left ventricular ejection fraction (LVEF).

According to an article in Med City News, the drug may have an advantage over the Bristol Myers Squibb drug mavacamten (sold under the brand name Camzyos) because there were no reports of worsening heart failure. In the Phase 3 EXPLORER trial of mavacamten, seven patients in the treatment group experienced reductions to their LVEF.  

Based on the projected success of aficamten, Cytokinetics stock price jumped by 83% and the company is said to be the subject of takeover interest from AstraZeneca and Novartis.

Cytokinetics plans to apply for FDA approval for the drug in the second half of 2024.

Complete results from SEQUOIA-HCM will be presented at an upcoming medical conference.

Viz.ai Receives FDA Approval for its HCM Detection Algorithm

Published on by hcmbeatLeave a comment

Viz.ai has received FDA approval for an artificial intelligence algorithm that can spot HCM from a standard electrocardiogram or EKG.

The algorithm automatically reviews EKGs as they are performed, and alerts the cardiology care team if it identifies a patient with suspected HCM.  Then, the care team is able to follow up with the patient and conduct further testing, if deemed appropriate.

The technology was developed through a collaboration between Viz.ai and Bristol Myers Squibb that was announced earlier this year.

Longer Term Results for Mavacamten

Published on by hcmbeatLeave a comment

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!

FDA Approves Mavacamten under Brand Name Camzyos

At long last, there is a FDA approved drug specifically intended for the treatment of hypertrophic cardiomyopathy.  After several years of testing, and based on the results of the groundbreaking EXPLORER-HCM trial, Bristol Myers Squibb’s new drug mavacamten, being marketed under the brand name Camzyos, is now available to HCM patients.

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.

VALOR-HCM Trial – Mavacamten vs. Septal Reduction Therapy – RESULTS ARE IN!

Published on by hcmbeat5 Comments

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.

FDA Approval of Mavacamten Delayed

Published on by hcmbeat3 Comments

The U.S. Food and Drug Administration (FDA) has postponed the date by which it must complete its review of mavacamten – the first drug made specifically to treat HCM. The FDA was originally scheduled to announce its decision in late January 2022, but that date has now been postponed until April 28, 2022, which is the new “PDUFA date” or the date by which the FDA must respond to the new drug application.  

The FDA has not asked Bristol Myers Squibb (BMS) to submit any additional data, but it wants to spend more time reviewing the proposed Risk Evaluation Mitigation Strategy or REMS which is the safety profile of the drug.  The FDA can require REMS for certain drugs with safety concerns to ensure that the benefits of the medication will outweigh any risks.

BMS acquired the drug mavacamten, a first in class myosin inhibitor, through its $13.1 billion acquisition of San Francisco biotech company MyoKardia late last year.

BMS Launches New HCM Awareness Campaign Featuring Utah Jazz Player Jared Butler

Published on by hcmbeatLeave a comment

Bristol Myers Squibb has launched a new hypertrophic cardiomyopathy awareness campaign and website entitled “Could it be HCM?” The campaign launch is in connection with the expected early 2022 FDA approval for the first-in-class cardiac myosin inhibitor drug mavacamten, 

A video made for the campaign features professional basketball player Jared Butler of the Utah Jazz.  In the video, Butler shares his surprise and dismay when he learned of his HCM diagnosis. Butler was fortunate that he was cleared to play basketball by his doctors at the Mayo Clinic who continue to follow him closely.  He was even featured in People Magazine talking about his HCM. See also this article in the Salt Lake Tribune.

The website described what happens to the heart in HCM,  the symptoms of HCM, and provides resources for dealing with a diagnosis of HCM.
