Considerations for the Development of Chimeric Antigen Receptor T 
Cell Products; 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 ``Considerations for the 
Development of Chimeric Antigen Receptor (CAR) T Cell Products; 
Guidance for Industry.'' The guidance is intended to assist sponsors, 
including industry and academic sponsors, developing ex vivo-
manufactured CAR T cell products. The guidance provides CAR T cell 
specific recommendations regarding chemistry, manufacturing, and 
control (CMC), pharmacology and toxicology, and design of clinical 
studies for oncology indications (including hematologic malignancies 
and solid tumors). The guidance announced in this notice finalizes the 
draft guidance of the same title dated March 2022.

DATES: The announcement of the guidance is published in the Federal 
Register on January 30, 2024.

SUPPLEMENTARY INFORMATION:

I. Background

    FDA is announcing the availability of a document entitled 
``Considerations for the Development of Chimeric Antigen Receptor (CAR) 
T Cell Products; Guidance for Industry.'' The guidance is intended to 
assist sponsors, including industry and academic sponsors, developing 
ex vivo-manufactured CAR T cell products. The guidance provides CAR T 
cell specific recommendations regarding CMC, pharmacology and 
toxicology, and design of clinical studies for oncology indications 
(including hematologic malignancies and solid tumors). Recommendations

[[Page 5911]]

specific to autologous or allogeneic CAR T cell products are noted in 
the guidance. The guidance also provides recommendations for analytical 
comparability studies for CAR T cell products. While the guidance 
specifically focuses on CAR T cell products, some of the information 
and recommendations provided may also be applicable to other 
genetically modified lymphocyte products, such as CAR Natural Killer 
cells or T cell receptor modified T cells.
    In the Federal Register of March 16, 2022 (87 FR 14893), FDA 
announced the availability of the draft guidance of the same title 
dated March 2022. FDA received numerous comments on the draft guidance 
and those comments were considered as the guidance was finalized. 
Changes to the guidance include clarifying the scope, focusing on 
treatment for oncology indications, and the recommendations for CAR T 
cells manufactured using cellular starting material from patients who 
have received CAR T cells previously, potency for CAR T cells that 
express multiple transgene elements, stability studies, and clinical 
monitoring. In addition, editorial changes were made to improve 
clarity. The guidance announced in this notice finalizes the draft 
guidance dated March 2022.
    Elsewhere in this issue of the Federal Register, FDA is announcing 
the availability of another human gene therapy final guidance entitled 
``Human Gene Therapy Products Incorporating Human Genome Editing; 
Guidance for Industry.''
    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 ``Considerations for the Development of 
Chimeric Antigen Receptor (CAR) T Cell 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.

II. Paperwork Reduction Act of 1995

    While this guidance contains no collection of information, it does 
refer to previously approved FDA collections of information. The 
previously approved collections of information are subject to review by 
the Office of Management and Budget (OMB) under the Paperwork Reduction 
Act of 1995 (44 U.S.C. 3501-3521). The collections of information in 21 
CFR part 50 have been approved under OMB control number 0910-0130; the 
collections of information in 21 CFR part 211 have been approved under 
OMB control number 0910-0139; the collections of information in 21 CFR 
part 312 have been approved under OMB control number 0910-0014; the 
collections of information in 21 CFR part 601 have been approved under 
OMB control number 0910-0338; and the collections of information in 21 
CFR part 1271 have been approved under OMB control number 0910-0543.
