Taysha Gene Therapies announced that it has joined with Catalent, a pharmaceutical services provider, to support production of its potential gene therapies for disorders that include CLN1 Batten disease and Rett syndrome.

“Through this partnership, we will be able to enhance our existing manufacturing capabilities to support Taysha’s broad gene therapy pipeline,” R.A. Session, the president, founder, and CEO of Taysha, said in a press release.

Taysha currently has over a dozen experimental therapies in various stages of development. The company focuses on disorders of the central nervous system (CNS) — the brain and spinal cord — that are caused by changes to single genes, so-called monogenic CNS disorders.

“We are focused on ensuring that we can provide access to potentially curative gene therapies for thousands of patients by establishing this robust infrastructure early,” Session added.

Under the November agreement, Catalent will manufacture Taysha’s products at its gene therapy manufacturing facilities in Maryland.

“With our experience in process and analytical development and deep expertise in adeno-associated viral vectors, combined with our growing footprint, we are able to help companies manufacture patient material and reach the clinic faster,” said Manja Boerman, PhD, president of Catalent.

Adeno-associated viruses (AAV) are harmless viruses often used to carry therapeutic genes to patient cells. AAV vectors form the backbone of Taysha’s gene therapy pipeline.

In addition to its agreement with Catalent, Taysha has partnered with UT Southwestern Medical Center, where Session also holds a position as entrepreneur-in-residence. This partnership grants Taysha access to the university’s 500-liter capacity CGMP-compliant manufacturing facility.

CGMP, meaning current good manufacturing practices, are a set of regulations governing quality care in drug manufacturing. CGMP regulations cover minimum requirements for the methods, facilities, and controls used to manufacture, process, and package drug products.

Taysha also plans to establish its own commercial-scale CGMP manufacturing facility to further support large-scale production of future gene therapies, including those for CLN1 and Rett.

“Given Taysha’s large and growing pipeline of gene therapies, we wanted to plan for potential increased manufacturing needs above the GMP facility at UT Southwestern and our own planned manufacturing facility,” said Fred Porter, PhD, Taysha’s chief technical officer. “We believe that this partnership is critical to our strategy for future clinical and commercial supply of our gene therapy product candidates.”

Over the past year, Taysha has partnered with various pharmaceutical companies to support programs enabling rapid diagnoses for patients with lysosomal storage disorders and epileptic conditions, such as Batten disease, and to collaboratively advance potential gene therapies.

Managing Quality and Regulatory Risks in Pharmaceutical Technology Transfer

Technology transfer moves more than manufacturing instructions. It moves process knowledge, supplier dependencies, labeling requirements, packaging specifications, and the evidence needed to demonstrate control. For medical device manufacturers, including those supporting drug-device combination products, these interfaces can become recurring sources of compliance gaps during site transitions, acquisitions, and remediation. The central problem is often not a missing procedure. It is a quality system that allows connected activities to change independently. A label revision may be approved while packaging artwork, supplier instructions, or production-system data still reflect an obsolete version. Staying inspection-ready requires manufacturers to manage these dependencies as one controlled system. Why Compliance Gaps Keep Recurring Findings are treated as documentation defects Revising a procedure can resolve an immediate discrepancy without changing the behavior that caused it. If unclear decision rights, weak escalation, or ineffective training remain, the same failure may surface elsewhere. Corrective and preventive action should distinguish the observed finding from its underlying cause and establish how effectiveness will be demonstrated. Ownership is divided across connected functions Quality, Regulatory Affairs, labeling, packaging engineering, operations, suppliers, and digital-system owners often maintain separate workflows. Each team may complete its assigned task while an interface remains uncontrolled. For example, changing an instruction for use can affect packaging configuration, translations, technical documentation, inventory disposition, and release controls. Transitions expose unresolved weaknesses Acquisitions and site transfers can introduce conflicting procedures, incomplete knowledge transfer, or different assumptions about validated processes. Regulatory changes add further demands. When these events coincide with CAPA or change-control backlogs, teams may prioritize administrative closure over risk reduction. Without a coordinated impact assessment, local fixes can create new gaps downstream. Establish the Regulatory Baseline Inspection readiness starts with knowing which requirements apply to the product, activity, and market. Pharmaceutical, device, and combination-product obligations are not interchangeable; transfer planning should identify the applicable requirements rather than assume one quality framework covers every operation. According to FDA’s Quality Management System Regulation overview and FAQs, the QMSR became effective on February 2, 2026, incorporates ISO 13485:2016 by reference, and introduced the updated device inspection process under Compliance Program 7382.850. ISO 13485 certification does not exempt a manufacturer from FDA inspection or guarantee compliance with FDA requirements. For devices marketed in the European Union, Regulation (EU) 2017/745, Annex I, Section 23, provides the primary requirements for information supplied with devices, including labels and instructions for use. Teams should assess the applicable provisions alongside relevant language, product-specific, and market requirements. A labeling review should therefore evaluate required content and consistency with the device’s intended purpose and supporting documentation—not merely artwork accuracy. How to Identify the Real Gaps Begin with a cross-functional assessment that follows actual product and information flows. Select representative transfers, label changes, supplier changes, and CAPAs, then trace each from initiation through implementation and effectiveness review. Map dependencies: Identify affected specifications, suppliers, packaging components, systems, validation activities, and training. Compare records with practice: Check whether approved procedures match what operators and reviewers actually do. Test traceability: Follow a requirement through technical documentation, labeling, production instructions, and release evidence. Examine recurrence: Look for repeated deviations, reopened actions, overdue changes, and findings shared across sites. Assess capacity: Determine whether qualified owners have enough time and authority to complete corrective work. Prioritize gaps by potential patient or user harm, regulatory impact, likelihood of recurrence, and detectability. Document the rationale; an old overdue item is not automatically more important than a newly identified high-risk weakness. Align Quality, Labeling, Packaging, and Change Control Create a coordinated remediation plan with one accountable owner for each action, named contributors, acceptance criteria, and required evidence. Separate immediate containment from systemic correction. Containment might prevent obsolete labels from being issued; correction might redesign approval and implementation controls so obsolete versions cannot return. Use change control as the integration point. Before approval, evaluate effects on regulatory submissions or notifications, technical documentation, supplier controls, packaging performance, validation, electronic master data, inventory, and training. Record both identified impacts and justified decisions that particular activities are unaffected. During technology transfer, define readiness gates before production or release responsibilities move. These should address the transfer of process knowledge, acceptance criteria, receiving-site capability, required qualification or validation, approved documents, and personnel competence. The appropriate evidence depends on the product and process; a generic checklist cannot replace a documented assessment. Finally, verify implementation where the work happens. Confirm that current instructions are available, suppliers received approved requirements, systems contain correct versions, and affected personnel can perform their tasks. A signed approval is not evidence that every downstream change took effect. Mistakes That Undermine Inspection Readiness Closing CAPAs on task completion alone: Effectiveness checks should test whether the underlying failure has been controlled. Updating labels in isolation: Assess packaging, supplier, system, documentation, and inventory consequences. Counting closures instead of evidence: Dashboards need defensible records behind their status indicators. ...
