FDA Issues Draft Guidance to Facilitate Development of Human Gene Therapy, CAR T Cell, and Regenerative Medicine Products – Wilson Sonsini Goodrich…

August 19th, 2022 2:10 am

The Center for Biologics Evaluation and Research (CBER) of the U.S. Food and Drug Administration (FDA) updated its Guidance Agenda in June 2022,1which provides that the agency plans to issue 18 guidance documents in 2022, including eight guidance documents on tissues and advanced therapies. In this alert, we highlight some key considerations from three draft guidance documents on human gene therapy products that incorporate gene editing (GE) components, chimeric antigen receptor (CAR) T cell products, and regenerative medicine therapies that can benefit biopharmaceutical developers and sponsors. Recognizing the challenges of developing such complex, multi-component biologic drug products, including unanticipated risks associated with on-target and off-target activities, these draft guidance documents describe the FDA's recommendations for preclinical and clinical testing, chemistry, manufacturing, and controls (CMC), as well as information that should be included in investigational new drug (IND) applications to ensure proper identity, potency/strength, quality, and purity of the investigational drug products. FDA recommends sponsors of such complex products to communicate with the Office of Tissues and Advanced Therapies (OTAT) in CBER early in product development before submission of an IND, to discuss the product-specific considerations in preparation for transitioning to the clinical phase.

FDA expects detailed information and data IND applications before sponsors can transition to clinical testing. We recommend biopharmaceutical developers and sponsors review the applicable FDA draft guidance documents early in their product development process to identify these needs. Work closely with both FDA regulatory counsel and intellectual property/patent counsel to ensure there is sufficient data to support an IND application, including adequate testing and quality control measures, and that CMC, preclinical, and clinical development plans are coordinated with intellectual property and patent strategies to ensure robust protection of their intellectual property and to maximize the benefits of their patents and FDA regulatory exclusivities. We also encourage interested persons to submit comments to shape the policies proposed in FDA's draft guidance documents prior to finalization.

Draft Guidance for Industry: Human Gene Therapy Products Incorporating Genome Editing2

Draft Guidance for Industry: Considerations for the Development of Chimeric Antigen Receptor (CAR) T Cell Products3

Draft Guidance for Industry: Voluntary Consensus Standards Recognition Program for Regenerative Medicine Therapies4

Stakeholders have until September 14, 2022, to submit comments to this draft guidance to ensure they are considered by FDA before finalization of the guidance.
