Cytokinetic’s Drug Aficamten & Upcoming HCM Summit – Interview with Dr. Martin Maron

Editor’s note:  You have probably noticed a distinct uptick in clinical trials of potential treatments for hypertrophic cardiomyopathy.  HCMBeat has been following this trend and has previously published a host of stories about such trials, including this story about the positive results from the REDWOOD-HCM Phase 2 clinical trial, as well as past stories discussing the biopharmaceutical company Cytokinetics, its  drug aficamten (previously known as CK-274), and the REDWOOD-HCM trial.

Some of these earlier stories are as follows:

Positive Signs from REDWOOD-HCM

Cytokinetics Moves Forward with HCM Drug Trial

Recently, Cynthia Waldman of HCMBeat had the opportunity to speak over Zoom with Dr. Martin Maron, who recently served as the principal investigator of Cytokinetics’ REDWOOD trial.  The conversation focused both on Cytokinetic’s drug aficamten (previously known as CK-274), and the new class of drugs known as “myosin inhibitors.”  What follows is a transcript of their conversation (which has been edited for readability).

Cytokinetics Announces Positive Results from REDWOOD-HCM Phase 2 Clinical Trial

Cytokinetics today announced positive topline results for its experimental drug CK-274 from its recent Phase 2 REDWOOD-HCM trial for patients who have obstructive hypertrophic cardiomyopathy (HOCM).

According to the press release, this drug, a next-in-class cardiac myosin inhibitor, showed consistent and meaningful reduction in left ventricular outflow tract gradients in HOCM with its effects evident within 2 weeks of starting the drug. The benefits continued until the end of treatment 10 weeks later. No patients had to  discontinue the drug or take a break from treatment due to reduced left ventricular ejection fraction. And, the drug was well tolerated and appeared to be free from significant side effects.

Cytokinetics plans to commence a Stage 3 for CK-274 trial by the end of 2021. Full results of the Stage 2 REDWOOD study will be presented at an upcoming scientific meeting.

Cytokinetics Moves Forward with HCM Drug Trial

This week Cytokinetics announced that the first patient in Cohort 2 of their REDWOOD-HCM trial has been dosed.

Cytokinetics is testing the safety and tolerability of the cardiac myosin inhibitor CK-274 for the potential treatment of hypertrophic cardiomyopathy.  The trial already enrolled completed enrollment of 18 patients in the first cohort.  Sites are located across North America and Europe and results are expected in the middle of this year.

Separately, Cytokinetics announced that CK-274 has been granted an orphan drug designation by the FDA. This designation confers certain benefits and financial incentives for drugs intended to treat conditions affecting fewer than 200,000 people in the U.S.

Cytokinetics Announces its Phase 2 Clinical Trial – “Redwood-HCM”

Cytokinetics today announced that its Phase 2 double-blind study of its experimental drug CK-274 entitled “REDWOOD-HCM” (Randomized Evaluation of Dosing With CK-274 in Obstructive Outflow Disease in HCM (hypertrophic cardiomyopathy) has begun enrollment.  The trial will enroll patients with symptomatic, obstructive HCM.

CK-274 is a next-generation cardiac myosin inhibitor which the company hopes will prove to be beneficial for the treatment of hypertrophic cardiomyopathy (HCM).

There are currently two companies in clinical trials for HCM:  Cytokinetics and MyoKardia. You can read more about their efforts here and here.
