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.

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!
Several years ago, researchers from the University of Virginia (UVA) and the University of Oxford announced a joint project involving a large international registry of hypertrophic cardiomyopathy (HCM) patients to facilitate research into HCM. Backed with funding from the National Heart Lung and Blood Institute, this project, known as the HCM Registry, includes data from 2,750 patients with HCM at 44 sites in six countries.
This week, researchers from UVA announced their first findings from this registry which suggest that HCM patients can be separated into two basic groups:
- Patients with a known genetic mutation who are not obstructed but have scarring of the heart muscle;
- Patients who do not have a known genetic mutation and do not exhibit scarring, but who do have a significant amount of obstruction to blood flow.
According to Dr. Christopher Kramer of UVA, this information should provide doctors with information that allows them to better assess the degree of risk to any particular patient, and to help inform a treatment strategy for each patient based on his or her unique profile.
