# SUPPLEMENTARY INFORMATION:

## I.  Background

FDA is announcing the availability of a draft guidance for industry entitled “Recommended Approaches to Integration of Genetic Toxicology Study Results.”  Risk for carcinogenesis is usually determined in rodent assays, in either 2-year studies or shorter-term studies using alternative models (ICH S1B).  Regulatory decisions involving both single- and repeat-dose clinical studies are discussed in this guidance.  Pharmaceuticals administered through oral, intravenous, topical, and other routes, as appropriate, are subject to this guidance.

This draft guidance is being issued consistent with FDA's good guidance practices regulation (21 CFR 10.115).  The draft guidance, when finalized, will represent the agency's current thinking on recommended approaches to integration of genetic toxicology study results.  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.

## II.  Comments

                    Interested persons may submit to the Division of Dockets Management (see                     **ADDRESSES**                    ) written or electronic comments on the draft guidance.  Two paper copies of mailed comments are to be submitted, except that individuals may submit one paper copy.  Comments are to be identified with the docket number found in brackets in the heading of this document.  The draft guidance and received comments are available for public examination in the Division of Dockets Management between 9 a.m. and 4 p.m., Monday through Friday.                

## III.  Electronic Access

                    Persons with access to the Internet may obtain the document at either                     *http://www.fda.gov/​cder/​guidance/​index.htm*                     or                     *http://www.fda.gov/​ohrms/​dockets/​default.htm*.
