Second Late-Breaking Presentation on Sunday to Showcase Results of Cellular Reprogramming Gene Therapy Treatment in Pig Model of Ischemic Heart Failure
Tenaya Management to Host Webcast Conference Call on Monday,November 10, 2025, to Review MyPEAK-1 Data
SOUTH SAN FRANCISCO, Calif., Nov. 04, 2025 (GLOBE NEWSWIRE) -- Tenaya Therapeutics, Inc. (NASDAQ: TNYA), a clinical-stage biotechnology company with a mission to discover, develop and deliver potentially curative therapies that address the underlying causes of heart disease, announced two late-breaking oral presentations at the American Heart Association (AHA) 2025 Scientific Sessions taking place November 7-10, 2025, in New Orleans, Louisiana.
The AHA presentation of new TN-201 clinical data will include interim safety and efficacy results from dose cohorts 1 and 2 in the MyPEAK-1 Phase 1b/2a clinical trial of TN-201. TN-201 is being developed for the potential treatment of myosin-binding protein C3 (MYBPC3)-associated hypertrophic cardiomyopathy (HCM), a condition caused by insufficient levels of myosin-binding protein C (MyBP-C).
Details of the TN-201 clinical data presentation are as follows:
Abstract Title:TN-201, an InvestigationalMYBPC3Gene Replacement Therapy: Interim Clinical Data from MyPEAK-1, a Phase Ib/2a Study Evaluating Safety and Early Efficacy of TN-201 in Adult Patients withMYBPC3-Associated Hypertrophic CardiomyopathySession Type:Late-Breaking Science: Main Event (Oral Presentation)Session Title:Forgotten No More: The Current Belle of the Ball? Breakthrough Evolutions in Hypertrophic CardiomyopathyPresenting Author:Milind Y Desai, M.D., MBA, director of the Hypertrophic Cardiomyopathy Center at Cleveland Clinic and vice chair of Cleveland Clinic’s Heart, Vascular & Thoracic InstitutePresentation Date & Time:Saturday, November 8, 2025, from 10:25 am – 10:35 am CT
Tenaya will also present results from a preclinical study of its cellular reprogramming treatment in a pig model of ischemic heart failure. The goal of reprogramming gene therapy is to improve heart function following ischemic injury through cardiac cell regeneration. Details for this late-breaking presentation are below:
Abstract Title:First Demonstration of Significant and Durable Improvement of Cardiac Function in Pig Model of Ischemic Heart Failure with Direct Reprogramming Delivered Precisely to Infarct Border via Guided Intramyocardial Injection CatheterSession Type:Late-Breaking Basic Science (Oral Presentation)Session Title:Next-Generation Therapies for Ischemic Heart Repair: From Cells to ImagingPresenting Author:Kathy Ivey, Senior Vice President of Research, Tenaya TherapeuticsPresentation Date & Time:Sunday, November 9, 2025, from 8:00 am – 8:10 am CT
Copies of the presentations at AHA Scientific Sessions 2025 will be available in the “Our Science” and “Investors” sections of the company’s website following each late-breaking session.
Conference Call and WebcastTenaya management will host a conference call on Monday, November 10, 2025, at 8:00 a.m. ET/5:00 a.m. PT to discuss the TN-201 data being presented at the upcoming American Heart Association Scientific Sessions 2025.
