Tenaya Therapeutics to Highlight Growing Capabilities in Capsid Engineering, Gene Editing and Manufacturing at the American Society of Gene and Cell Therapy 27th Annual Meeting

Abstracts Demonstrate Tenaya’s Continued Innovation Across Core Competencies Facilitating Current Pipeline and Enabling Next Wave of Precision Heart Medicines

SOUTH SAN FRANCISCO, Calif., May 02, 2024 (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, today announced that it will present seven abstracts focused on the company’s growing capabilities for discovering and advancing genetic medicines for heart disease at the upcoming American Society of Gene and Cell Therapy (ASGCT) 27^th Annual Meeting, being held May 7-11, 2024, in Baltimore, MD.

Tenaya has established integrated internal capabilities to broadly enable modality agnostic target validation and the design and manufacture of adeno associated virus (AAV)-based genetic medicines focused on the treatment of heart diseases. The company’s pipeline includes two clinical-stage gene therapies for cardiomyopathies, as well as earlier-stage research related to gene therapy, gene editing and cardiac cell regeneration, all using adeno-associated virus (AAV) as a delivery vehicle. Tenaya’s seven presentations at this year’s ASGCT will highlight new capsid engineering insights, the company’s emerging gene editing efforts, and manufacturing process optimizations intended to enhance the safety and efficacy profiles of AAV-based gene therapies.

Details of the presentations are as follows:

Capsid Engineering and Promoters
Tenaya has established an active capsid engineering effort encompassing the identification and comparison of known and novel capsids, which are then tested across multiple species to characterize transduction and expression in specific heart cells and/or liver detargeting. At ASGCT, new data from murine and non-human primate studies will be presented comparing previously identified AAV-based capsids, AAV9, AAVrh10 and AAVrh74, for cardiac cell tropism and transgene expression.

In two other posters, Tenaya scientists will present new data describing a novel approach to creating a library of promoters for cardiac-specific gene expression, as well as detailing efforts to design more compact cardiac-specific promoters to accommodate larger gene therapy or gene editing therapeutics.
