Tenaya's focus on capsid engineering, gene editing, and manufacturing process optimizations highlights its commitment to developing potentially curative therapies for heart disease.
Despite the positive presentations at the ASGCT 27th Annual Meeting, Tenaya Therapeutics may face challenges in scaling up manufacturing processes and increasing yields for gene therapies.
The company may encounter hurdles in optimizing the safety and efficacy profiles of AAV-based gene therapies, which could impact the development and commercialization of precision heart medicines.
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) 27th 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.
Wednesday Poster Session, May 8, 2024, at 12 pm ET
- AAV9, AAVrh.10, and AAVrh.74 Exhibit Different Cell Type Tropisms in the Heart Following Systemic Delivery and AAV9 Mediates Superior Cardiomyocyte Transgene Expression in Murine and NHP (abstract #2662)
Lead author: Ze Cheng, Ph.D., Senior Scientist
- Chimeric and Rationally Designed Compact Promoters for Cardiac-Specific Gene Expression (abstract #464)
- AAV DNA shuffle library of GH Loop Variable Regions for Directed Evolution of Cardiotropic Capsids (abstract #482)
Lead author: Prasad Konkalmatt, Associate Director, AAV Capsid Engineering
Gene Editing
Tenaya scientists will present preclinical results suggesting that gene editing of the R14del variant of the phospholamban (PLN) gene may hold promise as a treatment for PLN-R14del-associated dilated cardiomyopathy. Tenaya has developed a gene editing therapy utilizing a single AAV vector designed to deliver a proprietary self-inactivating CRISPR-Cas9 and PLN- R14del-mutation-specific single guide RNA. Previously, Tenaya shared data from a mouse model showing that the company’s gene editing vector corrected the PLN-R14del mutation while leaving the wild-type PLN gene intact resulting in preserved heart function, reduced fibrosis and extended survival. This year’s presentation will replicate that set of data in the same model of disease using self-inactivating vectors designed to decrease the risk of off-target edits without any diminishment of efficacy.
Friday Poster Session, May 10, 2024, at 12 pm ET
- Precision Editing of PLNR14del Mutation Using a Self-Inactivating, All-in-One AAV Vector to Rescue PLN-R14del-Associated Cardiomyopathy (abstract #1701)
Lead author: Huanyu Zhou, Ph.D., Senior Scientist
Product Development and Manufacturing
Clinical supply of TN-201 and TN-401 gene therapies was manufactured under current Good Manufacturing Practice regulations at Tenaya’s Genetic Medicines Manufacturing Center using the company’s proprietary Sf9 recombinant baculovirus (Sf9/rBV) production process at the 1000L scale. At ASGCT, Tenaya researchers will present abstracts related to increasing yield and scalability associated with Sf9/rBV manufacturing processes.
Tenaya has also internalized the HEK293 manufacturing platform up to the 200L scale. Tenaya researchers will present data on a novel small molecule additive that increases the productivity of HEK293-based AAV manufacturing processes, which may have implications for improved scalability, productivity and costs.
Friday Poster Session, May 10, 2024, at 12 pm ET
- Development of a Scalable High Yield HEK293 Expression Platform for AAV Manufacturing (abstract #1531)
