Taysha reports progress in Rett syndrome gene therapy trials

DALLAS - Taysha Gene Therapies, Inc. (NASDAQ: TSHA), a biotechnology firm specializing in gene therapies for central nervous system diseases, has disclosed recent updates on its clinical program TSHA-102, under evaluation for Rett syndrome. The company, currently valued at approximately $604 million, has seen its stock surge over 60% year-to-date, according to InvestingPro data. The company is set to present these findings at the upcoming 2025 International Rett Syndrome Foundation Scientific Meeting in Boston from June 9-11.

TSHA-102, an adeno-associated virus (AAV)-based gene therapy, is designed to deliver a functional form of the MECP2 gene to the central nervous system, addressing the genetic cause of Rett syndrome. The therapy has garnered multiple designations from the FDA, including Regenerative Medicine Advanced Therapy and Fast Track status, indicating its potential to address unmet medical needs.

The company will showcase three oral presentations at the conference. One highlights the safety and efficacy data from the REVEAL adolescent/adult and pediatric Phase 1/2 trials, scheduled for presentation on Wednesday, June 11. Another presentation on Tuesday, June 10, will share caregiver insights on the therapy’s impact on developmental milestones. The third will discuss preclinical data on the biodistribution of rAAV9 vectors in non-human primates, also slated for Tuesday. InvestingPro analysis reveals the company maintains a strong financial position with a current ratio of 5.35, indicating robust liquidity to support its clinical programs.

Additionally, Taysha will host a symposium on Tuesday, June 10, focusing on how natural history insights are redefining therapeutic development for Rett syndrome.

Rett syndrome, primarily affecting females, is a rare neurodevelopmental disorder with no approved disease-modifying treatments targeting the genetic root cause. It affects an estimated 15,000 to 20,000 patients in the U.S., EU, and U.K.

Taysha’s management team, with a track record in gene therapy development and commercialization, aims to rapidly advance treatments to patients. However, the company cautions that forward-looking statements are not guarantees of future performance and that actual results may differ due to various risks and uncertainties.
