[Docket No. FDA-2021-D-0669]


S1B(R1) Addendum to S1B Testing for Carcinogenicity of 
Pharmaceuticals; International Council for Harmonisation; Draft 
Guidance for Industry; Availability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the availability of a draft guidance for industry entitled ``S1B(R1) 
Addendum to S1B Testing for Carcinogenicity of Pharmaceuticals''. The 
draft guidance was prepared under the auspices of the International 
Council for Harmonisation (ICH), formerly the International Conference 
on Harmonisation. The draft guidance expands the testing scheme for 
assessing human carcinogenic risk of small molecule pharmaceuticals by 
introducing an additional approach that is not described in the 
original S1B Guideline. The draft guidance is intended to offer an 
integrative approach that provides specific weight of evidence (WoE) 
criteria that inform whether or not a 2-year rat study adds value in 
completing a human carcinogenicity risk assessment. The Addendum also 
adds a plasma exposure ratio-based approach for setting the high dose 
in the rasH2-Tg mouse model, while all other aspects of the 
recommendations for high dose selection in S1C(R2) Guideline would 
still apply.

DATES: Submit either electronic or written comments on the draft 
guidance by December 6, 2021 to ensure that the Agency considers your 
comment on this draft guidance before it begins work on the final 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

SUPPLEMENTARY INFORMATION:

I. Background

    FDA is announcing the availability of a draft guidance for industry 
entitled ``S1B(R1) Addendum to S1B Testing for Carcinogenicity of 
Pharmaceuticals''. The guidance was prepared under the auspices of ICH. 
ICH has the mission of achieving greater regulatory harmonization 
worldwide to ensure that safe, effective, high-quality medicines are 
developed, registered, and maintained in the most resource-efficient 
manner.
    By harmonizing the regulatory requirements in regions around the 
world, ICH guidelines have substantially reduced duplicative clinical 
studies, prevented unnecessary animal studies, standardized the 
reporting of important safety information, standardized marketing 
application submissions, and made many other improvements in the 
quality of global drug development and manufacturing and the products 
available to patients.
    The six Founding Members of the ICH are FDA; the Pharmaceutical 
Research and Manufacturers of America; the European Commission; the 
European Federation of Pharmaceutical Industries Associations; the 
Japanese Ministry of Health, Labour, and Welfare; and the Japanese 
Pharmaceutical Manufacturers Association. The Standing Members of the 
ICH Association include Health Canada and Swissmedic. Additionally, the 
Membership of ICH has expanded to include other regulatory authorities 
and industry associations from around the world (refer to https://www.ich.org/).
    ICH works by involving technical experts from both regulators and 
industry parties in detailed technical harmonization work and the 
application of a science-based approach to harmonization through a 
consensus-driven process that results in the development of ICH 
guidelines. The regulators around the world are committed to 
consistently adopting these consensus-based guidelines, realizing the 
benefits for patients and for industry.
    As a Founding Regulatory Member of ICH, FDA plays a major role in 
the development of each of the ICH guidelines, which FDA then adopts 
and issues as guidance for industry. FDA's guidance documents do not 
establish legally enforceable responsibilities. Instead, they describe 
the Agency's current thinking on a topic and should be viewed only as 
recommendations, unless specific regulatory or statutory requirements 
are cited.
    In May 2021, the ICH Assembly endorsed the draft guideline entitled 
``S1B(R1) Addendum to S1B Testing for Carcinogenicity of 
Pharmaceuticals'' and agreed that the guideline should be made 
available for public comment. The draft guideline is the product of the 
Safety Expert Working Group of the ICH. Comments about this draft will 
be considered by FDA and the Safety Expert Working Group.
    The draft guidance provides guidance on expanding the testing 
scheme for assessing human carcinogenic risk of small molecule 
pharmaceuticals by introducing an additional approach that is not 
described in the original S1B Guideline and also adds a plasma exposure 
ratio-based approach for setting the high dose in the rasH2-Tg mouse 
model.
    This draft guidance has been left in the original ICH format. The 
final guidance will be reformatted and edited to conform with FDA's 
good guidance practices regulation (21 CFR 10.115) and style before 
publication. The draft guidance, when finalized, will represent the 
current thinking of FDA on ``S1B(R1) Addendum to S1B Testing for 
Carcinogenicity of Pharmaceuticals''. 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; the collections of information in 21 CFR part 314 
have been approved under OMB control number 0910-0001.
