AGENCY:

Food and Drug Administration, HHS.

ACTION:

Notice of availability.

SUMMARY:

The Food and Drug Administration (FDA or the Agency) is announcing the availability of a draft guidance for industry entitled “Immunogenicity Information in Human Prescription Therapeutic Protein and Select Drug Product Labeling—Content and Format.” This draft guidance provides recommendations for incorporating clinically relevant immunogenicity information into the labeling of products having immunogenicity assessments. Appropriate inclusion and consistent placement of immunogenicity information in the Prescribing Information helps to make clinically relevant information accessible to the health care practitioner and promotes the safe and effective use of prescription drug and biological products. When finalized, the recommendations in this guidance will supersede the immunogenicity labeling-specific recommendations in the guidances for industry entitled “Labeling for Biosimilar Products” and “Clinical Pharmacology Section of Labeling for Human Prescription Drug and Biological Products—Content and Format.”

DATES:

Submit either electronic or written comments on the draft guidance by April 5, 2022 to ensure that the Agency considers your comment on this draft guidance before it begins work on the final version of the guidance.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FDA is announcing the availability of a draft guidance for industry entitled “Immunogenicity Information in Human Prescription Therapeutic Protein and Select Drug Product Labeling—Content and Format.”

Evaluation of a therapeutic protein product's and certain select drug products' immunogenicity ( e.g., risk of developing anti-drug antibodies, including neutralizing antibodies) and its potential clinical impact generally plays an important role in the assessment of the product's safety and effectiveness for each proposed indication. Because some, but not all, anti-drug antibodies have been associated with safety concerns or loss of effectiveness, FDA believes that presenting immunogenicity information in a consistent manner would enable health care practitioners to more easily differentiate products associated with anti-drug antibodies having clinical effect(s) from products with anti-drug antibodies that do not have a clinically meaningful effect on pharmacokinetics, pharmacodynamics, safety, or effectiveness.

This draft guidance recommends the use of a dedicated Immunogenicity subsection (subsection 12.6) under the CLINICAL PHARMACOLOGY section. Information and statements to include in this subsection ( e.g., data on anti-drug antibody incidence, clinical pharmacologic effects of anti-drug antibodies) are described in the draft guidance, along with recommended content to include in other sections of the labeling ( e.g., summary of anti-drug antibody-associated effects on safety and/or effectiveness in the WARNINGS AND PRECAUTIONS, ADVERSE REACTIONS, and/or CLINICAL STUDIES sections, as applicable). The labeling recommendations are based on: (1) Adequacy of the methodology for detection of anti-drug antibodies, (2) sufficiency of available data to draw clinical conclusions, and (3) whether the anti-drug antibodies have clinically significant effect(s). In addition to recommendations on presentation of known immunogenicity information, this draft guidance also provides recommendations for consistently stating when such information is unknown, if appropriate. The draft guidance also provides procedural information, including recommendations for updating immunogenicity information in the Prescribing Information of applicable approved products.

When finalized, this guidance will supersede the immunogenicity labeling-specific recommendations from the guidance for industry entitled “Clinical Pharmacology Section of Labeling for Human Prescription Drug and Biological Products—Content and Format” (available at https://www.fda.gov/media/74346/download). When finalized, this guidance will also supersede the recommendations in section IV.C.3., ADVERSE REACTIONS, Immunogenicity, of the guidance for industry entitled “Labeling for Biosimilar Products” (available at https://www.fda.gov/media/96894/download), including the statement “Immunogenicity information for therapeutic protein products is usually placed in a subsection in the ADVERSE REACTIONS section entitled Immunogenicity” and statements recommended for inclusion as the first paragraph in the ADVERSE REACTIONS subsection that precedes the immunogenicity data. FDA has verified the website addresses as of the date this document publishes in the Federal Register , but websites are subject to change over time.

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 “Immunogenicity Information in Human Prescription Therapeutic Protein and Select Drug Product Labeling—Content and Format.” 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 new 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 314 have been approved under OMB control number 0910-0001. The collections of information in 21 CFR part 600 have been approved under OMB control number 0910-0308. The collections of information in 21 CFR part 601 have been approved under OMB control number 0910-0338. The collections of information in 21 CFR 201.56 and 201.57 have been approved under OMB control number 0910-0572. The collections of information related to pharmacology data have been approved under OMB control number 0910-0014. The collections of information submitting biologics license applications under section 351(k) of the Public Health Service Act have been approved under OMB control number 0910-0719.
