Cytokinetics announced this week the progression of REDWOOD-HCM, its ongoing Phase 2 clinical trial of CK-274, a cardiac myosin inhibitor for the treatment of HCM.
According to the press release, preliminary results show substantial reductions in left ventricular outflow tract gradients (LVOT), with only modest decreases in left ventricular ejection fraction. (LVEF).
Based on this early positive data, the study will continue and will enroll a second group of approximately 18 patients.
Cytokinetics hopes to have results from REDWOOD-HCM in the middle of 2021, and hopes to begin a Phase 3 trial for CK-274 by the end of 2021.
For detailed information about this trial see ClinicalTrials.gov.
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.
NEWS FROM MYOKARDIA
MyoKardia recently announced a new clinical trial of its drug, mavacamten (formerly known as MYK-461) which will compare the clinical results of mavacamten with septal reduction therapies currently used in clinical practice, i.e. the open heart surgical procedure known as septal myectomy and the catheter based procedure known as alcohol septal ablation.
The study will be run by the Cleveland Clinic with Dr. Milind Desai serving as principal investigator. MyoKardia expect to begin enrolling patients in early 2020.

NEWS FROM CYTOKINETICS:
Cytokinetics released positive data from its Phase 1 study of the drug currently known as CK-274 in a poster session at the HFSA 23rd Annual Scientific Meeting in Philadelphia. The study found that CK-274 was safe and well tolerated, while no serious adverse events or negative changes to vital signs, ECGs or laboratory tests were observed.
The company will now be moving into a Phase 2 clinical trial of CK-274 in patients with obstructive hypertrophic cardiomyopathy, expected to begin in late 2019.

MyoKardia’s experimental drug MYK-461, currently in Stage 2 trials for humans, has now been shown to eliminate left ventricular obstruction in five cats with HCM. It has already been shown to inhibit traits of HCM in mice.
Addressing these findings, Associate Professor Joshua Stern, chief of the Cardiology Service at the University of California, Davis, veterinary hospital, stated:
“There has been little to no progress in advancing the treatment of HCM in humans or animals for many years,” Stern said. “This study brings new hope for cats and people.”
Based on these positive results, U.C.Davis is hoping to conduct a clinical trial of MYK-461 to determine whether it could become the standard of care for cats with HCM.

Eleclazine: The Liberty HCM Trial
It appears to be the end of the road for the Gilead drug eleclazine, a late sodium channel inhibitor previously known as GS-6615. Eleclazine, with properties similar to the anti-angina drug ranolazine (which was approved by the FDA in 2006), was the subject of a recently terminated HCM clinical trial known as Liberty-HCM. The HCM eleclazine study focused on whether the drug would improve symptoms and exercise capacity in patients with HCM by increasing their peak oxygen uptake, resulting in improved VO2 max readings on exercise testing. The HCM study began enrolling patients in February 2015. Data collection had been scheduled to continue through June 2017. Continue reading “End of the Road for Eleclazine and Liberty HCM Study”
