Tenaya Therapeutics Gets Go-Ahead for HCM Gene Therapy Trial

Tenaya Therapeutics announced on Monday that they have received FDA clearance to begin a Phase 1 clinical trial of targeted gene therapy for HCM.

Tenaya is developing TN-201, a first in class adeno-associated virus based therapy being developed to treat HCM caused by mutation(s) in the MYBPC3 gene. They anticipate that the trial will begin in the third quarter of 2023. The therapy delivers one fully functional MYBPC3 gene to the patient via injection with a deactivated virus. Tenaya hopes that this therapy will restore normal levels of the MYBPC3 protein, thereby halting disease progression, and even potentially reversing the course of the disease, after just a single treatment.

The TN-201 Phase 1b clinical trial will be a multi-center, open-label study designed to assess the safety of an intravenous infusion of TN-201. They hope to enroll at least 6 symptomatic, non-obstructive HCM patients who carry the MYBPC3 gene and who already have received an automatic implantable cardioverter defibrillator (ICD) as part of their treatment plan to date.

The Future of HCM Treatment

Doctors from the University of Pennsylvania this week published an overview of current therapies available for the treatment of HCM.  While this article mentions all of the old standards – beta blockers, calcium channel blockers, myectomy and alcohol ablation, the real focus is on the future of HCM treatment. In particular, the article describes several new and/or experimental therapies which look promising for the future.

Gene Therapy – Is HCM Cure Possible?

A team of international genetic researchers has just won “The Big Beat Challenge” – a grant from the British Heart Foundation of £30 million ($36 million) payable over a 5 years period to study potentially curative gene therapies to treat genetic cardiomyopathies.

Gene Therapy for HCM

A recent article on Biospace.com describes a method of targeted gene therapy for HCM patients currently being developed by Tenaya Therapeutics. This therapy is intended for patients whose HCM is caused by a mutation in the MYBPC3 gene.

According to Tenaya CEO Faraz Ali, animal models show that this therapy can reverse declining heart function.

Scientists Seeking Patient Input: Gene Therapy to Treat Inherited Cardiomyopathies

A group of scientists working on gene therapy for inherited cardiomyopathies are seeking input from patients about their interest and willingness to participate in gene therapy trials. These researchers hope that treatment with gene therapy will ultimately prove to be a cure for hypertrophic cardiomyopathy as well as other genetic cardiomyopathies.

If you are interested in learning more about gene therapy and are willing to answer a few questions about your willingness to participate in this type of research, watch this video.  Then, fill out this short questionnaire.  It just takes a few minutes and you may help to find a cure for HCM.

Targeted Gene Therapy for HCM

The expanding field of personalized medicine has not left hypertrophic cardiomyopathy behind. In fact, two companies are currently developing targeted gene therapies for HCM patients. Each therapy targets a separate and distinct HCM gene mutation.

Tenaya Therapeutics, located in the San Francisco area, is developing a therapy called TN-201 which is directed at mutations in the Myosin Binding Protein C3 (MYBPC3) gene. The therapy has shown favorable results in mice.  In May of this year, Tenaya received Orphan Drug Designation from the U.S Food and Drug Administration. An Orphan Drug Designation confers certain tax and economic incentives on companies developing a treatment for rare conditions.

Meanwhile, this week, Lexeo Therapeutics acquired Stelios Therapeutics, a San Diego based company developing a therapy for HCM patients with a mutation in the TNNI3 gene. These TNNI3 patients comprise somewhere between 5% and 7% of all patients with HCM, or approximately 30,000 people.  The underpinnings of this research come from the University of California, San Diego.

HCMBeat will continue following these developments. It is a busy and exciting time in the treatment of HCM!
