Taysha is engaged in the development of intrathecally-delivered AAV gene therapies for monogenic CNS diseases. As a part of this platform approach, Taysha has a promising pipeline, including TSHA-102, which is the first-and-only gene therapy in clinical development for Rett syndrome, and TSHA-120, which is in Phase 1/2 development for the treatment of GAN and awaiting regulatory feedback.
Astellas is continuing to build its capability to bring novel gene therapies to patients, following the acquisition of Audentes (now Astellas Gene Therapies,
“Gene therapy is the corner stone of Astellas’ Primary Focus, Genetic Regulation*1; our goal is to bring new transformative treatment options to patients living with serious genetic diseases and limited treatment options,” said
“We are excited to enter this strategic investment with Astellas, a premier biopharmaceutical company with global R&D, manufacturing and commercial capabilities,” said RA Session II, Taysha’s Chief Executive Officer. “We believe this investment not only further validates the potential of our technology platform, but also reinforces the therapeutic and market opportunity of our two lead clinical assets.”
To further strategically align Astellas and Taysha, in connection with its equity investment, Astellas will receive one Board observer seat on Taysha’s Board of Directors, enabling Taysha to leverage Astellas’ gene therapy clinical and commercial expertise as Taysha advances TSHA-120 and TSHA-102.
*1: Astellas has established a Focus Area Approach for its research and development strategy. For more information, please visit our website at https://www.astellas.com/en/science/focus-area-approach.
TSHA-102 is a self-complementary intrathecally delivered AAV9 gene replacement therapy under development for the treatment of Rett syndrome. TSHA-102 utilizes the novel miRNA-Responsive Auto-Regulatory Element (miRARE) platform to regulate transgene expression genotypically on a cell-by-cell basis. The miRARE technology is designed to prevent toxicity associated with transgene overexpression and can be potentially utilized across other indications. TSHA-102 has received Orphan Drug and Rare Pediatric Disease designations from the
About Rett Syndrome
Rett syndrome is a severe genetic neurodevelopmental disorder caused by a mutation in the X-linked MECP2 gene essential for neuronal and synaptic function in the brain. Primarily occurring in females, Rett syndrome is one of the most common genetic causes of severe intellectual disability worldwide. Patients have normal early development, with symptom onset typically beginning between 6 to 18 months of age. Rett syndrome is characterized by rapid developmental regression that leads to intellectual disabilities, loss of speech, loss of purposeful use of hands, loss of mobility, seizures, cardiac impairments and breathing issues. Currently, there are no approved therapies that treat the underlying cause of this progressive disease.
TSHA-120, an intrathecally dosed AAV9 gene replacement therapy delivering the gene gigaxonin for the treatment of GAN, is currently being evaluated in an ongoing Phase 1/2 clinical trial. TSHA-120 has received Orphan Drug and Rare Pediatric Disease designations from FDA and Orphan Drug Designation from the
About Giant Axonal Neuropathy (GAN)
GAN is rare inherited genetic disorder that is a progressive neurodegenerative disease that affects both the central and peripheral nervous systems. The disease is caused by loss-of-function mutations in the gene coding for gigaxonin, which results in dysregulation of intermediate filament turnover, an important structural component of the cell. Children with GAN present before the age of five with symptoms including unsteady gait, frequent falls, and motor weakness. Currently, there are no approved treatments for GAN, which results in death for patients in their late teens or early twenties.
Taysha Gene Therapies (Nasdaq: TSHA) is on a mission to eradicate monogenic CNS disease. With a singular focus on developing curative medicines, we aim to rapidly translate our treatments from bench to bedside. We have combined our team’s proven experience in gene therapy drug development and commercialization with the world-class UT Southwestern Gene Therapy Program to build an extensive, AAV gene therapy pipeline focused on both rare and large-market indications. Together, we leverage our fully integrated platform—an engine for potential new cures—with a goal of dramatically improving patients’ lives. More information is available at www.tayshagtx.com.
