Taysha Gene Therapies is a gene therapy developer that manufactures gene-based treatments for medical conditions such as neurodegenerative diseases, neurodevelopmental diseases, and genetic epilepsies. The company uses edited genes via its AAV9 Capsid platform (a adeno-associated virus vector), which is used to make engineered genes replace mutated genes. Taysha’s solution is administered intrathecally to directly deliver gene therapeutics into the cerebrospinal fluid for more optimal distribution. The company is listed on the Nasdaq and trades under the symbol TSHA.
In February 2024, the company transferred the IP rights for several gene therapy programs to other organizations under a loan and security agreement. This move was in order to extend the company’s cash runway into 2026.
As of May 2024, the company had two gene therapy candidates in development, both for the treatment of Rett syndrome. Both candidates were in Phase I/II of clinical testing.
Key customers and partnerships
Taysha and pharmaceutical company Catalent partnered in November 2020 to support the development and manufacturing capabilities of Tysha’d gene therapeutics. Through the partnership Tysha would be able to use Catalent’s manufacturing facilities to produce its gene therapies.
