MyoKardia Announces Positive Results from EXPLORER Trial

MyoKardia today announced positive topline results for its experimental drug mavacamten from its recent Stage 3 EXPLORER trial for patients with obstructive hypertrophic cardiomyopathy or HCM.

According to the press release, the drug met all primary and secondary endpoints, while relieving outflow tract obstruction, improving symptoms and enhancing quality of life for the patients enrolled in the trial.  Furthermore, the drug was well tolerated and appeared to be free of significant side effects.

MyoKardia plans to seek FDA approval for mavacamten, the first drug specifically targeting the underlying biological mechanism of HCM, in the first quarter of 2021.

Full results of the EXPLORER study will be presented at a scientific meeting later this year.

More Positive Results for MyoKardia Drug

Findings from MyoKardia’s Phase 2 Maverick clinical trial of its experimental drug mavacamten in non-obstructive HCM were announced on Monday at the online 69th Annual Scientific Sessions of the American College of Cardiology.

Dr. Carolyn Ho of Harvard’s Brigham and Women’s Hospital reported to online viewers that mavacamten was generally well tolerated.  In addition, the drug showed promising results in this Phase 2 trial intended to demonstrate the safety of the drug. In particular, some relevant additional observations were reductions in blood levels of two biomarkers of cardiac stress and injury – namely  NT-proBNP which indicates hemodynamic stress, and cardiac troponin I, which is a biomarker of myocardial injury.

These findings look promising for non-obstructive HCM patients who currently have very limited treatment options.

The Future of HCM Care

Dr. Stephen Heitner, together with his colleagues at Oregon Health & Sciences University, published an article last week in the European Journal of Heart Failure which gives a glimpse into the treatment of hypertrophic cardiomyopathy (HCM) in the future.  Although recent publications have stated that the majority of HCM patients today have a favorable prognosis when receiving appropriate treatment, a heavy disease burden continues to be placed upon patients.  Hence, better and more effective treatments for HCM are still needed in order to lessen this burden.

HCM Clinical Trials – the Latest News

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.

Can a Smartwatch Detect HOCM?

According to a limited study recently published in Nature, researchers were able to detect obstructive HCM (HOCM) using a noninvasive optical sensor contained in many commercial smartwatches.

How the Technology Works

These watches used photoplethysmography, a noninvasive optical method used to detect blood volume changes in the microvascular bed at the skin surface.  The same technology is used in clinical pulse oximeters and is now widely incorporated in commercial smartwatches that have heart rate detection.

Positive Results for MyoKardia Drug Mavacamten

This week in the journal Annals of Internal Medicine, MyoKardia reported positive results from its open label phase 2 clinical trial of its drug mavacamten (formerly known as MYK-461) for obstructive hypertrophic cardiomyopathy. The study was conducted at 5 HCM centers and enrolled 21 subjects with  obstructive HCM. All subjects saw some degree of improvement to their condition after taking mavacamten.

How a Louis L’Amour Book about the Southwest Inspired a HCM Discovery

When Stanford biochemist Jim Spudich settled down in bed with a book recommended by his wife, he had no idea that the book would inspire one of the biggest discoveries of his career. Spudich drifted off to sleep while reading The Haunted Mesa, a science fiction novel by Louis L’Amour. His scientific discovery was based on an image he saw in his dreams when the image of a mesa morphed into a myosin molecule.

MyoKardia Drug Moves to Next Phase

According to this press release, MyoKardia expects to dose the first patient in the EXPLORER-HCM trial of mavacamten (formerly known as MYK-461) for obstructive HCM in the second quarter of 2018.

MyoKardia says that it expects 220 patients to enroll in the 30 week long trial.  These patients will be randomly assigned to receive either mavacamten or a placebo.  Participants will also be able to continue on their normal beta blockers or calcium channel blockers.
