SUPPLEMENTARY INFORMATION:

I. Background

FDA is announcing the availability of a document entitled “Long Term Follow-Up After Administration of Human Gene Therapy Products; Guidance for Industry.” This guidance provides a brief introduction of the product characteristics, patient-related factors, and the preclinical and clinical data that should be considered when assessing the need for LTFU observations for your GT product. This guidance also describes the Agency's current recommendations for the conduct of LTFU studies, specifically the information/data to support a sponsor's rationale for the duration and design of a LTFU protocol when clinical trials are initiated. Also included this guidance are GT product-specific clinical considerations for monitoring subjects under a LTFU protocol and recommendations on patient monitoring for licensed GT products. This guidance is intended to supersede the guidance entitled “Guidance for Industry: Gene Therapy Clinical Trials—Observing Participants for Delayed Adverse Events” dated November 2006. This guidance supplements the guidance entitled “Testing of Retroviral Vector-Based Human Gene Therapy Products for Replication Competent Retrovirus during Product Manufacture and Patient Follow-up; Draft Guidance for Industry”.

In the Federal Register of July 12, 2018 (83 FR 32311), FDA announced the availability of the draft guidance of the same title dated July 2018. FDA received several comments on the draft guidance and those comments were considered as the guidance was finalized. The guidance announced in this notice finalizes the draft guidance dated July 2018.

This guidance is being issued consistent with FDA's good guidance practices regulation (21 CFR 10.115). The guidance represents the current thinking of FDA on “Long Term Follow-Up After Administration of Human Gene Therapy Products.” It does not establish any rights for any person and is not binding on FDA or the public. You can use an alternative approach if it satisfies the requirements of the applicable statutes and regulations.
