Tenaya Therapeutics Showcases Breakthroughs in Gene Therapy Research
Tenaya Therapeutics, Inc. (NASDAQ: TNYA), a pioneering biotechnology firm located in South San Francisco, is on a mission to revolutionize the treatment of heart disease. The company specializes in discovering, developing, and delivering potentially curative therapies aimed at addressing the root causes of cardiovascular issues.
Recently, Tenaya announced its participation in the upcoming American Society of Gene and Cell Therapy (ASGCT) 28th Annual Meeting. During this renowned event, Tenaya will present five compelling abstracts reflecting its groundbreaking research initiatives.
Abstract Presentations at ASGCT
The abstracts to be featured are a result of Tenaya's commitment to advancing its core competencies in areas like capsid engineering, as well as the identification and optimization of genetic medicines targeting cardiomyocytes. Furthermore, the company is enhancing its manufacturing processes for adeno-associated virus (AAV) gene therapies.
Refining Capsid Engineering Capabilities
One of the abstracts focuses on refining capsid engineering capabilities through high-throughput experimental screening. By leveraging both in vivo and in silico screening methods, Tenaya researchers have efficiently identified several novel capsid candidates. These capsids were tested against AAV serotype 9 (AAV9)—which is known for its effective cardiomyocyte targeting—and some candidates even outperformed AAV9 in murine models, significantly advancing cardiac gene therapy.
Innovations in Prime Editing
Another significant highlight will be Tenaya's development of prime editing techniques specifically aimed at cardiomyocytes. Researchers created a prototype that utilizes a dual-cassette system delivered via two AAV capsids, incorporating cardiomyocyte-specific regulatory elements. In preclinical studies, this prime editing prototype successfully corrected mutations in a murine model of RBM20-related dilated cardiomyopathy (DCM), paving the way for promising therapeutic applications.
Development of TN-501 Gene Editing Therapy
Tenaya will also present outcomes related to its TN-501 gene editing candidate. Aimed at treating PLN-R14del-associated DCM, TN-501 is engineered to specifically target and inactivate the mutant phospholamban allele. Preclinical trials demonstrated that low doses of TN-501 markedly improved cardiac function and reduced fibrosis while being well-tolerated in murine models, underscoring its transformative potential in heart disease treatment.
Advancements in Manufacturing Techniques
The company is also proud of its achievements in establishing scalable manufacturing processes. Tenaya successfully implemented Sf9/rBV-based production at a large scale for its AAV gene therapy programs, while also developing a novel HEK293-based manufacturing process that promises enhanced yields and cost-efficiency. This innovation represents a significant step towards creating affordable AAV gene therapies that can reach a wider patient population.
