[Docket No. FDA-2021-D-0776]

Studying Multiple Versions of a Cellular or Gene Therapy Product 
in an Early-Phase Clinical Trial; Guidance for Industry; Availability

AGENCY: Food and Drug Administration, HHS.

ACTION: Notice of availability.

-----------------------------------------------------------------------

SUMMARY: The Food and Drug Administration (FDA or Agency) is announcing 
the availability of a final guidance entitled ``Studying Multiple 
Versions of a Cellular or Gene Therapy Product in an Early-Phase 
Clinical Trial; Guidance for Industry.'' The guidance document provides 
recommendations to sponsors interested in studying multiple versions of 
a cellular or gene therapy product in an early phase clinical trial for 
a single disease. Sponsors have expressed interest in gathering 
preliminary evidence of safety and activity using multiple versions of 
a cellular or gene therapy product in a single clinical trial, where 
each version of the product is distinct and is generally submitted to 
FDA in a separate investigational new drug application (IND). The 
guidance provides recommendations for conducting such studies, 
including how to organize and structure the INDs, submit new 
information, and report adverse events. The guidance announced in this 
notice finalizes the draft guidance of the same title dated September 
2021.

DATES: The announcement of the guidance is published in the Federal 
Register on November 7, 2022.

SUPPLEMENTARY INFORMATION:

I. Background

    FDA is announcing the availability of a document entitled 
``Studying Multiple Versions of a Cellular or Gene Therapy Product in 
an Early-Phase Clinical Trial; Guidance for Industry.'' The guidance 
document provides recommendations to sponsors interested in studying 
multiple versions of a cellular or gene therapy product in an early 
phase clinical trial for a single disease. Sponsors have expressed 
interest in gathering preliminary evidence of safety and activity using 
multiple versions of a cellular or gene therapy product in a single 
clinical trial, where each version of the product is distinct and is 
generally submitted to FDA in a separate IND. The objective of these 
early phase clinical studies is to guide which version(s) of the 
product to pursue for further development in later phase studies. Thus, 
these studies are not intended to provide primary evidence of 
effectiveness to support a marketing application and generally are not 
adequately powered to demonstrate a statistically significant 
difference in efficacy between the study arms. The guidance provides 
recommendations for conducting such studies, including how to organize 
and structure the INDs, submit new information, and report adverse 
events.
    In the Federal Register of September 30, 2021 (86 FR 54207), FDA 
announced the availability of the draft guidance entitled ``Studying 
Multiple Versions of a Cellular or Gene Therapy Product in an Early 
Phase Clinical Trial.'' FDA received several comments on the draft 
guidance and those comments were considered as the guidance was 
finalized. Changes to the guidance include clarifying how to continue 
the umbrella trial after a study arm has been closed and adding 
examples of changes that result in multiple versions of a cellular or 
gene therapy product. In addition, editorial changes were made to 
improve clarity. The guidance announced in this notice finalizes the 
draft guidance of the same title dated September 2021.
    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 ``Studying Multiple Versions of a Cellular 
or Gene Therapy Product in an Early-Phase Clinical Trial.'' 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.

II. Paperwork Reduction Act of 1995

    While this guidance contains no collection of information, it does 
refer to previously approved FDA collections of information. Therefore, 
clearance by the Office of Management and Budget (OMB) under the 
Paperwork Reduction Act of 1995 (PRA) (44 U.S.C. 3501-3521) is not 
required for this guidance. The previously approved collections of 
information are subject to review by OMB under the PRA. The collections 
of information in 21 CFR part 312 and Form FDA 1572 have been approved 
under OMB control number 0910-0014.
