Studying Multiple Versions of a Cellular or Gene Therapy Product 
in an Early Phase Clinical Trial; Draft Guidance for Industry; 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 draft document entitled ``Studying Multiple 
Versions of a Cellular or Gene Therapy Product in an Early-Phase 
Clinical Trial; Draft Guidance for Industry.'' The draft guidance 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 is a distinct product that should be 
submitted to FDA in a separate investigational new drug application 
(IND). The draft guidance describes the regulatory framework for 
conducting such studies, including recommendations on how to organize 
and structure the INDs, submit new information, and report adverse 
events.

DATES: Submit either electronic or written comments on the draft 
guidance by December 29, 2021 to ensure that the Agency considers your 
comment on this draft guidance before it begins work on the final 
version of the guidance.

ADDRESSES: You may submit comments on any guidance at any time as 
follows:

SUPPLEMENTARY INFORMATION:

I. Background

    FDA is announcing the availability of a draft document entitled 
``Studying Multiple Versions of a Cellular or Gene Therapy Product in 
an Early-Phase Clinical Trial; Draft Guidance for Industry.'' The draft 
guidance document provides recommendations to sponsors interested in 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 is a distinct product 
that should be 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 draft guidance 
describes the regulatory framework for conducting such studies, 
including recommendations on how to organize and structure the INDs, 
submit new information, and report adverse events.
    This draft guidance is being issued consistent with FDA's good 
guidance practices regulation (21 CFR 10.115). The draft guidance, when 
finalized, will represent 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.

III. Electronic Access

    Persons with access to the internet may obtain the draft guidance 
at either https://www.fda.gov/vaccines-blood-biologics/guidance-compliance-regulatory-information-biologics/biologics-guidances,
