Drug-Drug Interaction Assessment for Therapeutic Proteins; 
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 for industry entitled ``Drug-Drug 
Interaction Assessment for Therapeutic Proteins.'' With the continued 
market growth and increased clinical use of therapeutic proteins, it is 
important to understand the nature of and the potential for drug-drug 
interactions (DDIs) with these products. The purpose of this guidance 
is to help sponsors of investigational new drug applications (INDs) and 
applicants of biologics license applications (BLAs) determine the need 
for DDI studies for a therapeutic protein by providing a systematic, 
risk-based approach. This guidance finalizes the draft guidance of the 
same title issued on August 10, 2020.

DATES: The announcement of the guidance is published in the Federal 
Register on June 5, 2023.

ADDRESSES: You may submit either electronic or written comments on 
Agency guidances at any time as follows:

SUPPLEMENTARY INFORMATION:

I. Background

    FDA is announcing the availability of a guidance for industry 
entitled ``Drug-Drug Interaction Assessment for Therapeutic Proteins.'' 
With the continued market growth and increased clinical use of 
therapeutic proteins, it is important to understand the nature of and 
the potential for DDIs with these products. This guidance supplements 
the final FDA guidances for industry entitled ``In Vitro Drug 
Interaction Studies--Cytochrome P450 Enzyme- and Transporter-Mediated 
Drug Interactions'' and ``Clinical Drug Interaction Studies--Cytochrome 
P450 Enzyme- and Transporter-Mediated Drug Interactions'' (January 
2020) by providing recommendations for a systematic, risk-based 
approach to determining the need for DDI studies for therapeutic 
proteins. This guidance discusses considerations for assessing DDIs for 
therapeutic proteins, including situations where determining the DDI 
potential of a therapeutic protein is warranted. The guidance also 
discusses various types of DDI assessments,

[[Page 36589]]

considerations for study design, and recommendations for labeling.
    This guidance finalizes the draft guidance entitled ``Drug-Drug 
Interaction Assessment for Therapeutic Proteins'' issued on August 10, 
2020 (85 FR 48259). FDA considered comments received on the draft 
guidance as the guidance was finalized. Changes from the draft to the 
final guidance include: (1) clarifying that FDA review divisions should 
be consulted related to novel modalities, and that limitations exist in 
knowledge related to effect of therapeutic proteins on transporters; 
(2) including more literature references; (3) limiting the text related 
to antibody-drug conjugates (ADCs) because a draft guidance on clinical 
pharmacology considerations for ADCs has been published; and (4) 
including language about potential use of various modeling approaches 
on a case by case basis. In addition, editorial changes were made to 
improve clarity.
    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 ``Drug-Drug Interaction Assessment for 
Therapeutic Proteins.'' 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 for the submission of investigational new drug 
applications in 21 CFR part 312 have been approved under OMB control 
number 0910-0014. The collections of information for the submission of 
new drug applications in 21 CFR part 314 have been approved under OMB 
control number 0910-0001. The collections of information for the 
submission of biologics license applications in 21 CFR part 601 have 
been approved under OMB control 0910-0338. The collections of 
information pertaining to the submission of prescription drug labeling 
under 21 CFR 201.56 and 201.57 have been approved under OMB control 
number 0910-0572.
