With a singular focus on addressing significant unmet medical needs, TSHA is dedicated to the transformation of treatment paradigms for rare and complex neurological disorders through its innovative research and development approach.
Core Business Areas and Pipeline
The company’s primary focus lies in the development of gene therapies that target the genetic root cause of debilitating disorders. Its pipeline includes multiple product candidates designed to address monogenic disorders, including TSHA-101 for GM2 gangliosidosis, TSHA-102 for Rett syndrome, TSHA-103 for SLC6A1 haploinsufficiency disorder, TSHA-104 for Surfeit Locus 1 deficiency, and TSHA-118 for CLN1 disease. Each therapy utilizes advanced AAV vector technology to deliver functional genes directly to vital areas of the CNS, with TSHA-102 at the forefront of their clinical programs, being evaluated through intrathecal administration.
Technology and Innovation
Utilizing a clinically and commercially proven AAV9 capsid, TSHA employs a sophisticated delivery mechanism that incorporates a novel miRNA-Responsive Auto-Regulatory Element (miRARE) technology. This allows for precise, cell-by-cell regulation of gene expression, thereby mitigating risks such as overexpression while ensuring therapeutic benefits. The emphasis on a robust manufacturing process and process validation reflects the company’s commitment to both innovation and quality. Such a technology platform not only enhances safety profiles but also supports the durable, long-term efficacy required for treatments targeting complex CNS disorders.

Taysha Gene Therapies will present biodistribution data from an analysis of 28 non-human primates (NHPs) at the 31st Annual ESGCT Congress in Rome. The analysis, spanning five studies, evaluated AAV9 gene therapy vector delivery using intrathecal (IT) and intra-cisterna magna (ICM) administration.
Key findings include:
- Lumbar IT administration led to widespread and consistent biodistribution across brain and spinal cord regions
- IT and ICM administration achieved comparable biodistribution in NHPs
- Results support IT administration as an effective, safe, and minimally invasive approach for delivering AAV-based gene therapies for CNS diseases in children and adults
The data reinforces Taysha's clinical development strategy, particularly for their TSHA-102 program targeting Rett syndrome. The poster presentation, titled 'Broad CNS Biodistribution of AAV9-based Gene Therapies Delivered by Intrathecal Lumbar Puncture in Non-Human Primates,' will be presented on October 23, 2024.
