Exhibit 99.1
Taysha Gene Therapies Reports Fourth Quarter and Full Year 2021 Financial Results and Provides Corporate Update
Strategic pipeline prioritization initiatives focused on giant axonal neuropathy (GAN), with feedback on registration pathway by mid-2022, and Rett syndrome, with preliminary clinical data expected by year-end 2022 under recently approved Clinical Trial Application (CTA)
Rett syndrome affects over 350,000 patients worldwide; GAN has an estimated addressable patient population of 5,000 worldwide
Activities for other ongoing clinical programs will be minimized and all additional research and development will be paused to increase operational focus and efficiency
Pipeline prioritization initiatives, existing cash and financing under current debt facility expected to extend cash runway into Q4 2023
Dallas – March 31, 2022 - Taysha Gene Therapies, Inc. (Nasdaq: TSHA), a patient-centric, pivotal-stage gene therapy company focused on developing and commercializing AAV-based gene therapies for the treatment of monogenic diseases of the central nervous system (CNS) in both rare and large patient populations, today reported financial results for the fourth quarter and full-year ended December 31, 2021 and provided a corporate update.
“2021 was a year of accomplishment that included positive data from three clinical programs, including GAN, GM2 gangliosidosis and CLN7 disease. We are sharpening our strategic focus to prioritize key value-driving registration-directed programs in GAN, which has an estimated addressable patient population of 5,000 worldwide, and Rett syndrome, which affects over 350,000 patients worldwide,” noted RA Session II, President, Founder and CEO of Taysha. “To increase operational efficiency, activities for other ongoing clinical programs will be minimized and all additional research and development will be paused. As a result, we have reduced our workforce by approximately 35 percent. Our strategic pipeline prioritization, along with existing cash and financing under our current debt facility is expected to extend cash runway into the fourth quarter of 2023.”
Recent Corporate Highlights
TSHA-120 for giant axonal neuropathy (GAN): an intrathecally dosed AAV9 gene therapy currently being evaluated in a clinical trial for the treatment of GAN, a rare inherited genetic disorder that affects both the central and peripheral nervous systems and is caused by loss-of-function mutations in the gene coding for gigaxonin. TSHA-120 is designed to deliver a functional copy of the GAN gene to the CNS and PNS. The addressable patient population for GAN is estimated at 5,000 worldwide. TSHA-120 has received Orphan Drug and Rare Pediatric Disease designations from the U.S. Food and Drug Administration (FDA).
| • | Reported positive clinical efficacy and safety data for high dose cohort and long-term durability data across all therapeutic dose cohorts for TSHA-120 in GAN |
| • | Efficacy data for high dose cohort demonstrated clinically meaningful and statistically significant improvement in MFM32 by Year 1 compared to natural history (n=3) |
| • | Long-term durability data across all therapeutic dose cohorts demonstrated a 10-point improvement in mean change in MFM32 by Year 3 compared to estimated natural history decline of 24 points (n=5) |
| • | Biopsy data in five of six patient samples analyzed to date confirmed active regeneration of nerve fibers following treatment with TSHA-120 (n=6) |
| • | TSHA-120 was safe and well-tolerated supported by 53 patient-years of clinical data |
TSHA-102 in Rett syndrome: 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. TSHA-102 is the first-and-only gene therapy in clinical development for Rett syndrome. Rett syndrome affects an estimated 350,000 patients worldwide. TSHA-102 has received Orphan Drug and Rare Pediatric Disease designations from the FDA and has been granted Orphan Drug designation from the European Commission.
| • | Clinical Trial Application (CTA) approved by Health Canada in March 2022 |
| • | Positive preclinical data for TSHA-102 in mouse models of Rett syndrome |
| • | One-time IT injection of TSHA-102 significantly increased survival at all dose levels, with the mid to high doses improving survival across all age groups compared to vehicle-treated controls |
| • | Treatment with TSHA-102 significantly improved body weight, motor function and respiratory assessments in MECP2 knockout mice |
| • | Additional study in neonatal mice ongoing, with preliminary data suggesting normalization of survival |
| • | Positive IND/CTA-enabling 6-month GLP toxicology data |
| • | Biodistribution, as reflected by DNA copy number, was observed in multiple areas of the brain, sections of spinal cord and the dorsal root ganglion (DRG) |
| • | mRNA levels across multiple tissues were low, indicating miRARE regulation is minimizing transgene expression from the construct in the presence of endogenous MECP2 as expected, despite the high levels of DNA that were delivered |
| • | No toxicity from transgene overexpression was observed, confirmed by functional and histopathologic evaluations demonstrating no detrimental change in neurobehavioral assessments and no adverse tissue findings on necropsy |
TSHA-101 for GM2 gangliosidosis: the first bicistronic gene therapy in clinical development designed to deliver two genes – HEXA and HEXB, comprising the alpha and beta sub-units of ß-Hexosaminidase A, intrathecally for the treatment of GM2 gangliosidosis, also called Tay-Sachs or Sandhoff disease. TSHA-101 has been granted Orphan Drug and Rare Pediatric Disease designations by the FDA and Orphan Drug designation from the European Commission.
| • | Positive initial biomarker data for TSHA-101 demonstrating normalization of ß-hexosaminidase A enzyme activity in patients with GM2 gangliosidosis |
| • | Patient 1 with Sandhoff disease achieved Hex A enzyme activity of 190% of normal at Month 1 and 288% of normal at Month 3, representing 38-fold and 58-fold above the presumed asymptomatic level of 5% of normal identified by natural history at Month 1 and Month 3 respectively |
| • | Patient 2 with Tay-Sachs disease achieved Hex A enzyme activity of 25% of normal at Month 1, representing 5-fold above the presumed asymptomatic level of 5% of normal identified by natural history. This patient was only eligible for the Month 1 analysis at the time of data release |
| • | TSHA-101 was well-tolerated with no significant drug-related events |
| • | Patient 1 succumbed to pneumonia and pleural effusion with a concomitant hospital-acquired MRSA infection. |
| • | The independent data safety monitoring board (DSMB) concluded the patient death was unrelated to study drug |
| • | We do not intend to pursue further enrollment in the Phase 1/2 trial but will continue to follow patients who were previously dosed |
AAV9 Gene Replacement for CLN7 Batten disease: an investigational AAV9 intrathecally dosed gene replacement therapy designed to deliver a full-length copy of the CLN7 gene to potentially treat CLN7 disease, a rapidly progressing rare lysosomal storage disease with no approved treatments. The clinical development of the CLN7 program is in collaboration with UT Southwestern (UTSW) and Children’s Health and funded by Children’s Medical Center Foundation.
| • | Reported positive preliminary clinical safety data for first-generation construct in CLN7 Batten disease from UTSW-sponsored clinical trial |
| • | Data on the initial three patients dosed were presented at the 18th Annual WORLDSymposium in February 2022 by Dr. Saima Kayani, MD of UTSW |
| • | Fourth patient with CLN7 disease recently dosed at 1.0 x 1015 total vg |
| • | Future CLN7 development will focus solely on the first-generation construct |
2022 Prioritization Initiatives
| • | Prioritize key value-driving registration-directed programs, GAN and Rett syndrome |
| • | Initial clinical studies in CLN1 and SLC13A5 will limit patient enrollment to focus on proof-of-concept |
| • | Continued CLN7 clinical development in collaboration with existing partners |
| • | All additional research and development activities will be paused to increase operational efficiency |
| • | Reduction in workforce by approximately 35 percent with a focus on strategic prioritization |
Anticipated 2022 Milestones
| • | Regulatory update for TSHA-120 in GAN by mid-2022 |
| • | First-in-human preliminary Phase 1/2 data for TSHA-102 in Rett syndrome by year-end 2022 |
| • | Initiation of clinical development for TSHA-105 in SLC13A5 deficiency in 2022 |
| • | Continued clinical development for TSHA-118 in CLN1 disease in 2022 |
| • | Continued clinical development of the first-generation construct for CLN7 disease in 2022 |
