ACTION:

Notice.

SUMMARY:

The Food and Drug Administration (FDA) is announcing the availability of a guidance entitled “S2(R1) Genotoxicity Testing and Data Interpretation for Pharmaceuticals Intended for Human Use” (ICH S2(R1)). This guidance was prepared under the auspices of the International Conference on Harmonisation of Technical Requirements for Registration of Pharmaceuticals for Human Use (ICH). The ICH S2(R1) combines and replaces two ICH guidances, “S2A Specific Aspects for Regulatory Genotoxicity Tests for Pharmaceuticals” and “S2B Genotoxicity: A Standard Battery for Genotoxicity Testing of Pharmaceuticals.” ICH S2(R1) provides guidance to drug sponsors on which tests should be performed to assess potential genotoxicity of pharmaceuticals. It also provides guidance on testing conditions, data interpretation, and followup strategies if a positive response is seen in in vitro assays. This guidance is intended to provide drug sponsors with recommendations to ensure that drugs are appropriately tested for potential to cause genetic damage and to ensure efficient development of new drugs.

DATES:

Submit either electronic or written comments on Agency guidances at any time.

ADDRESSES:

Submit written requests for single copies of the guidance to the Division of Drug Information, Center for Drug Evaluation and Research, Food and Drug Administration, 10903 New Hampshire Ave., Bldg. 51, Rm. 2201, Silver Spring, MD 20993-0002, or the Office of Communication, Outreach and Development (HFM-40), Center for Biologics Evaluation and Research (CBER), Food and Drug Administration, 1401 Rockville Pike, suite 200N, Rockville, MD 20852-1448.

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 tripartite 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 among three regions: The European Union, Japan, and the United States. The six ICH sponsors are the European Commission; the European Federation of Pharmaceutical Industries Associations; the Japanese Ministry of Health, Labour, and Welfare; the Japanese Pharmaceutical Manufacturers Association; the Centers for Drug Evaluation and Research and Biologics Evaluation and Research, FDA; and the Pharmaceutical Research and Manufacturers of America. The ICH Secretariat, which coordinates the preparation of documentation, is provided by the International Federation of Pharmaceutical Manufacturers Associations (IFPMA).

The ICH Steering Committee includes representatives from each of the ICH sponsors and the IFPMA, as well as observers from the World Health Organization, Health Canada, and the European Free Trade Area.

In the Federal Register of March 26, 2008 (73 FR 16024), FDA published a notice announcing the availability of a draft guidance entitled “S2(R1) Genotoxicity Testing and Data Interpretation for Pharmaceuticals Intended for Human Use.” The notice gave interested persons an opportunity to submit comments by May 12, 2008.

After consideration of the comments received and revisions to the guidance, a final draft of the guidance was submitted to the ICH Steering Committee and endorsed by the three participating regulatory Agencies in November 2011.

The purpose of the ICH S2(R1) revision is to provide guidance on optimizing the standard genetic toxicology battery for prediction of potential human risks, and on interpreting results, with the goal of improving risk characterization for carcinogenic effects that have their basis in changes in the genetic material. The revised guidance describes internationally agreed-upon standards for followup testing and interpretation of positive results in vitro and in vivo in the standard genetic toxicology battery, including assessment of nonrelevant findings.

This guidance is being issued consistent with FDA's good guidance practices regulation (21 CFR 10.115). The guidance represents the Agency's current thinking on this topic. It does not create or confer any rights for or on any person and does not operate to bind FDA or the public. An alternative approach may be used if such approach satisfies the requirements of the applicable statutes and regulations.
