Guidance & Outlook
Regulatory Pathway for TSHA-102: The company has reaffirmed alignment with the FDA on the planned pathway toward a BLA submission for TSHA-102. This includes pivotal trial design, endpoints, and submission scenarios, with the potential for approval based on a 6-month interim analysis from the REVEAL pivotal trial. The BLA-enabling PPQ campaign using the TSHA-102 commercial manufacturing process began in April 2026 and is expected to be completed by Q4 2026. The FDA has agreed that clinical and commercial manufacturing processes are comparable, supporting the use of clinical data across all studies in the BLA submission.
Clinical Trials and Data Reporting: Dosing in the REVEAL pivotal trial and ASPIRE trial is on track for completion in Q2 2026. Longer-term data from Part A of the REVEAL Phase I/II trials, including at least 12 months of follow-up data from 12 patients, will be reported later this quarter. The data will include functional gains and clinical outcome measures, with the potential to strengthen the BLA package and support expedited submission.
Commercial Strategy: The company is building its internal commercial infrastructure, including assembling a commercial leadership team with expertise in strategy, pre-commercial planning, and product launch. Additional details on commercial plans are expected to be shared in the second half of 2026.
Market Opportunity and Product Differentiation: TSHA-102 is positioned as a minimally invasive gene therapy for Rett syndrome, with a lumbar intrathecal delivery method preferred by clinicians and caregivers. Preclinical data supports the efficacy and safety of this approach, and the company aims to provide broad access to treatment across various institutions.
Financial Outlook: The company expects its current cash resources of $276.6 million to fund planned operating expenses into 2028.

Key Q&A
Q:What is the significance of higher MECP2 protein expression with the self-complementary AAV9?
A:The self-complementary AAV9 construct drives a 30x transduction efficiency or protein expression compared to single strand, allowing for less invasive administration routes like intrathecal. This construct also shows rapid onset and persistent clinical improvements across various domains, regardless of genotype or age.
Q:What are the scenarios for the BLA submission pathway for TSHA-102?
A:The company prefers full approval based on 6-month data, though the FDA generally prefers 12-month data for gene therapy. The FDA is open to reviewing the totality of evidence for 6-month data. If 12-month data is required, the company plans to push for a rolling review to expedite the process.
Q:Can the company leverage the FDA's real-time clinical monitoring program for REVEAL?
A:The company is monitoring the program but has not committed to leveraging it due to its evolving nature and lack of formalized timelines and criteria. They are focused on their current scenarios for regulatory approval.
Q:Will the company stop enrollment at 15 patients for REVEAL Part B, or could there be over-enrollment?
A:The company may over-enroll slightly to account for potential screen failures. Over-enrollment would have minimal impact on statistical calculations, as the null hypothesis is very low.
Q:How does the Part B portion of the study compare to Part A?
A:Part B includes more rigorous and standalone assessments of milestones, with videos adjudicated by blinded raters. The methodology is similar to Part A but designed to capture more milestones.
Q:What should be expected from the 12-month follow-up data in the 2Q update?
A:The company expects to show continued improvement in early milestones and the development of new, more complex milestones. They do not anticipate a plateau in clinical improvements.
Q:What feedback has the FDA provided regarding the 6-month interim data for TSHA-102?
A:The FDA has not provided definitive feedback but is open to considering 6-month data for approval, depending on the totality of evidence.
Q:What is the importance of enrolling a broad age range in the study?
A:85% of the Rett syndrome population is over the age of 10. Demonstrating efficacy across all age groups is crucial for broad adoption and meeting the needs of the patient community.
Q:What is the enthusiasm level from the patient community for the trial?
A:There is high enthusiasm and demand across all age groups, with multiple centers of excellence participating and many patients eager to enroll.
Q:How often are patients assessed in Part A, and will there be updates beyond 12 months?
A:Patients are assessed quarterly after 12 months, and updates beyond 12 months will be included in future data disclosures.
Q:What redundancies exist in the TSHA-102 manufacturing chain?
A:The company uses Catalent's FDA-inspected facility in Baltimore, which has extensive gene therapy manufacturing experience. They are evaluating additional redundancies to mitigate potential disruptions.
Q:What is the preference for intrathecal delivery versus other routes?
A:Intrathecal delivery is preferred due to its less invasive nature, scalability, and efficiency compared to ICV, which requires OR time and neurosurgeon involvement.
Q:What is the screen fail rate for the trial, and what are the reasons?
A:Screen failures are minimal. The trial's criteria, such as the requirement for open milestones, may lead to some screen failures, but the impact on enrollment is negligible.
Q:Review of Unclear Management Responses
A:Management avoided providing a direct answer regarding leveraging the FDA's real-time clinical monitoring program, citing its evolving nature and lack of formalized timelines and criteria.
