Conference call and live webcast today at 4:30 PM Eastern Time
Dallas – November 13, 2024 – Taysha Gene Therapies, Inc. (Nasdaq: TSHA) (Taysha or the Company), a clinical-stage biotechnology company focused on advancing adeno-associated virus (AAV)-based gene therapies for severe monogenic diseases of the central nervous system (CNS), today reported financial results for the third quarter ended September 30, 2024, and provided a corporate update.
“We are pleased with the progress made with the FDA on further elucidating the potential regulatory pathway for TSHA-102 as we advanced discussions on the trial design, endpoints and potential use of an established natural history dataset for Part B of our REVEAL trials. Additionally, we aligned on a meeting cadence to expedite the development plan for TSHA-102,” said Sean P. Nolan, Chairman and Chief Executive Officer of Taysha. “We are in a strong position with CMC, having obtained FDA approval to use the pivotal product in our REVEAL trials based on the successful demonstration of analytical comparability. Subsequently, we released the pivotal product manufactured with the final commercial manufacturing process that we intend to use in Part B.”
Mr. Nolan continued, “Clinical data presented from the adult patients with the most advanced stage of the disease treated with the low dose of TSHA-102 indicate a pattern of early clinical improvements and functional gains across multiple domains within four weeks post-treatment that persisted and strengthened over time. As the pediatric data mature, we anticipate that the early clinical improvements and functional gains observed should also persist and strengthen over time in the pediatric patients treated with TSHA-102. We look forward to reporting longer-term data from the low dose cohort and data from the high dose cohort of both REVEAL trials in the first half of 2025. We plan to continue working closely with the FDA through the RMAT mechanism to solidify the regulatory pathway for TSHA-102 based on the totality of data and remain focused on execution as we prepare for what we expect to be an impactful year ahead.”

Third Quarter 2024 Financial Highlights
Research and Development Expenses: Research and development expenses were $14.9 million for the three months ended September 30, 2024, compared to $11.8 million for the three months ending September 30, 2023. The $3.1 million increase was driven by an $0.8 million increase in GMP batch activities during the three months ended September 30, 2024, which is representative of the intended commercial manufacturing process for TSHA-102 in Rett syndrome. Additionally, compensation for R&D employees increased as a result of higher headcount, and this was partially offset by lower consultant and contractor expenses.
General and Administrative Expenses: General and administrative expenses were $7.9 million for the three months ended September 30, 2024, compared to $8.6 million for the three months ended September 30, 2023. The decrease of $0.7 million was primarily due to the decrease in issuance costs allocated to the liability-classified 2023 pre-funded warrants associated with the August 2023 financing.
Net loss: Net loss for the three months ended September 30, 2024, was $25.5 million, or $0.1 per share, compared to a net loss of $117.1 million, or $0.93 per share, for the three months ended September 30, 2023. The reduction in net loss in 2024 was primarily due to a non-cash loss of $100.5 million recorded in 2023 from a change in fair value of warrant liability from the 2023 pre-funded warrants associated with the August 2023 financing.
Cash and cash equivalents: As of September 30, 2024, Taysha had $157.7 million in cash and cash equivalents. Taysha expects that its current cash resources will support planned operating expenses and capital requirements into the fourth quarter of 2026.

About TSHA-102
TSHA-102 is a self-complementary intrathecally delivered AAV9 investigational gene transfer therapy in clinical evaluation for Rett syndrome. Designed as a one-time treatment, TSHA-102 aims to address the genetic root cause of the disease by delivering a functional form of MECP2 to cells in the CNS. TSHA-102 utilizes a novel miRNA-Responsive Auto-Regulatory Element (miRARE) technology designed to mediate levels of MECP2 in the CNS on a cell-by-cell basis without risk of overexpression. TSHA-102 has received Regenerative Medicine Advanced Therapy, Fast Track and Orphan Drug and Rare Pediatric Disease designations from the FDA, Orphan Drug designation from the European Commission and Innovative Licensing and Access Pathway designation from the Medicines and Healthcare products Regulatory Agency.
About Rett Syndrome
Rett syndrome is a rare neurodevelopmental disorder caused by mutations in the X-linked MECP2 gene encoding methyl CpG-binding protein 2 (MeCP2), which is essential for regulating neuronal and synaptic function in the brain. The disorder is characterized by loss of communication and hand function, slowing and/or regression of development, motor and respiratory impairment, seizures, intellectual disabilities and shortened life expectancy. Rett syndrome progression is divided into four key stages, beginning with early onset stagnation at 6 to 18 months of age followed by rapid regression, plateau and late motor deterioration. Rett syndrome primarily occurs in females and is one of the most common genetic causes of severe intellectual disability. Currently, there are no approved disease-modifying therapies that treat the genetic root cause of the disease. Rett syndrome caused by a pathogenic/likely pathogenic MECP2 mutation is estimated to affect between 15,000 and 20,000 patients in the U.S., EU, and U.K.
