Tenaya Therapeutics to Present Data for TN-301 and TN-201 at Upcoming Medical Conferences

TN-301 First-in-Human Phase 1 Clinical Trial Results and Preclinical Combination Data to be Presented at Heart Failure Society of America Annual Scientific Meeting

TN-201 Interim Seroprevalence Study Data and Phase 1b Clinical Trial Design to be Featured at Hypertrophic Cardiomyopathy Medical Society Scientific Sessions

SOUTH SAN FRANCISCO, Calif., Sept. 21, 2023 (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 today that poster presentations related to its TN-201 and TN-301 programs will be presented at the 2023 Hypertrophic Cardiomyopathy Medical Society (HCMS) Scientific Sessions taking place October 6, 2023, and at the Heart Failure Society of America (HFSA) Annual Scientific Meeting occurring October 6-9, 2023. Both meetings are being held this year in Cleveland, Ohio.

TN-301 is Tenaya’s proprietary, highly selective small molecule inhibitor of histone deacetylase 6 (HDAC6) being developed for the potential treatment of heart failure with preserved ejection fraction (HFpEF). Data to be presented at HFSA will include results from the company’s Phase 1 clinical trial of TN-301 in healthy adult participants. Tenaya has previously reported that TN-301 was generally well tolerated and that target engagement was achieved. The company will also present new data from preclinical studies examining the effects of its HDAC6 inhibitor in combination with an approved HFpEF treatment in a model of disease.

TN-201 is Tenaya’s lead gene therapy candidate being developed for the treatment of hypertrophic cardiomyopathy (HCM) caused by mutations in the Myosin Binding Protein C3 (MYBPC3). TN-201 is designed to deliver a fully functional therapeutic MYBPC3 gene to the heart muscle cells. At the HCMS meeting, Tenaya will highlight the clinical trial design for its Phase 1b clinical trial in nonobstructive patients with MYBPC3-associated HCM as well as sharing interim data from an ongoing seroprevalence study.

Details of the presentations are as follows:
