SUMMARY: The Food and Drug Administration (FDA or Agency) is announcing

Antibody Development Programs.'' This guidance provides recommendations 
to assist industry and other parties involved in the development of 
bispecific antibodies. The guidance focuses on general regulatory and 
scientific considerations for bispecific antibodies, but not on 
development of a particular bispecific antibody. This guidance 
finalizes the draft guidance of the same title issued on April 19, 
2019.

DATES: The announcement of the guidance is published in the Federal 
Register on May 25, 2021.

SUPPLEMENTARY INFORMATION:

I. Background

    FDA is announcing the availability of a guidance for industry 
entitled ``Bispecific Antibody Development Programs.'' The regulatory 
pathway for evaluation of monoclonal antibodies is well established, 
but additional guidance is warranted regarding antibody-based products 
that target more than one antigen. This guidance addresses challenges 
that may arise during development of bispecific antibodies and provides 
recommendations regarding the type of data necessary to support 
approval.
    This guidance finalizes the draft guidance of the same title issued 
on April 19, 2019 (84 FR 16512). FDA considered comments received on 
the draft guidance as the guidance was finalized. In addition to minor 
editorial changes to improve clarity, changes from the draft to the 
final guidance include:
     Emphasis on discussing unique aspects of the quality, 
nonclinical, and clinical development programs for bispecific 
antibodies
     Clarification regarding potential immunogenicity 
associated with bispecific antibodies
     Clarification of clinical assessments comparing a 
bispecific antibody and an approved monospecific product(s)
    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 ``Bispecific Antibody Development 
Programs.'' 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 have been approved under OMB control 
number 0910-0014.

III. Electronic Access

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