ICH S3A Guidance: Note for Guidance on Toxicokinetics: The 
Assessment of Systemic Exposure in Toxicity Studies--Questions and 
Answers; International Council for Harmonisation; Draft Guidance for 
Industry; Availability

AGENCY: Food and Drug Administration, HHS.

ACTION: Notice.

-----------------------------------------------------------------------

SUMMARY: The Food and Drug Administration (FDA or Agency) is announcing 
the availability of a draft guidance entitled ``ICH S3A Guidance: Note 
for Guidance on Toxicokinetics: The Assessment of Systemic Exposure in 
Toxicity Studies--Questions and Answers.'' The draft guidance was 
prepared under the auspices of the International Council for 
Harmonisation (ICH), formerly the International Conference on 
Harmonisation. This question and answer (Q&A) guidance provides 
additional information to facilitate interpretation of the ``S3A 
Guidance: The Assessment of Systemic Exposure in Toxicity Studies'' 
(S3A guidance), especially to address the benefit and use of 
microsampling techniques in main study animals. The Q&A guidance is 
intended to provide points to consider before incorporating the 
microsampling method in toxicokinetic studies, and acknowledges the 
benefits (and some limitations) of the use of microsampling.

DATES: Although you can comment on any guidance at any time (see 21 CFR 
10.115(g)(5)), to ensure that the Agency considers your comment on this 
draft guidance before it begins work on the final version of the 
guidance, submit either electronic or written comments on the draft 
guidance by December 7, 2016.

SUPPLEMENTARY INFORMATION: 

I. Background

    In recent years, many important initiatives have been undertaken by 
regulatory authorities and industry associations to promote 
international harmonization of regulatory requirements. FDA has 
participated in many meetings designed to enhance harmonization and is 
committed to seeking scientifically based harmonized technical 
procedures for pharmaceutical development. One of the goals of 
harmonization is to identify and then reduce differences in technical 
requirements for drug development among regulatory Agencies.
    ICH was organized to provide an opportunity for harmonization 
initiatives to be developed with input from both regulatory and 
industry representatives. FDA also seeks input from consumer 
representatives and others. ICH is concerned with harmonization of 
technical requirements for the registration of pharmaceutical products 
for human use among regulators around the world. The six founding 
members of the ICH are the European Commission; the European Federation 
of Pharmaceutical Industries Associations; the Japanese Ministry of 
Health, Labour, and Welfare; the Japanese Pharmaceutical Manufacturers 
Association; CDER and CBER, FDA; and the Pharmaceutical Research and 
Manufacturers of America. The Standing Members of the ICH Association 
include Health Canada and Swissmedic. Any party eligible as a Member in 
accordance with the ICH Articles of Association can apply for 
membership in writing to the ICH Secretariat. The ICH Secretariat, 
which coordinates the preparation of documentation, operates as an 
international nonprofit organization and is funded by the Members of 
the ICH Association.
    The ICH Assembly is the overarching body of the Association and 
includes representatives from each of the ICH members and observers. In 
May 2016, the ICH Assembly endorsed the draft guidance entitled ``ICH 
S3A Guidance: Note for Guidance on Toxicokinetics: The Assessment of 
Systemic Exposure in Toxicity Studies--Questions and Answers'' and 
agreed that the guidance should be made available for public comment. 
The draft guidance 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 Q&A guidance provides additional information to 
facilitate interpretation of the S3A guidance. The S3A guidance has 
been successfully implemented since 1994, and in recent years, 
analytical method sensitivity has improved, allowing microsampling 
techniques to be used in toxicokinetic assessment. This Q&A guidance 
focuses on points to consider before incorporating the microsampling 
method in toxicokinetic studies, acknowledges the benefits (and some 
limitations) of the use of microsampling for assessing toxicokinetics 
in main study animals, and acknowledges the overall important 
contribution of microsampling to the 3Rs benefits (Replacement, 
Reduction, and Refinement), by reducing or eliminating the need for 
toxicokinetic satellite animals.
    The draft Q&A guidance is intended to apply to the majority of 
pharmaceuticals and biopharmaceuticals; however, for all types of 
molecules, consideration should be given on a case-by-case basis as to 
whether the sensitivity of the measurement method is appropriate with 
the small sample volumes available.
    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 ICH ``S3A 
Guidance: Note for Guidance on Toxicokinetics: The Assessment of 
Systemic Exposure in Toxicity Studies--Questions and Answers.'' 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.
