M7(R1) Addendum to ICH M7; International Conference on Harmonisation; Draft Guidance for Industry; Availability

The Food and Drug Administration (FDA or Agency) is announcing the availability of a draft guidance entitled ``M7(R1) Addendum to ICH M7: Assessment and Control of DNA Reactive (Mutagenic) Impurities in Pharmaceuticals to Limit Potential Carcinogenic Risk; Application of the Principles of the ICH M7 Guidance to Calculation of Compound- Specific Acceptable Intakes.'' The draft guidance was prepared under the auspices of the International Conference on Harmonisation of Technical Requirements for Registration of Pharmaceuticals for Human Use (ICH). This draft guidance, an addendum to the ICH M7 guidance of May 28, 2015, provides guidance on acceptable intake limits derived for some chemicals that are considered to be mutagens and carcinogens, and that were selected because they are commonly used in pharmaceutical manufacturing or are useful in illustrating the principles for deriving compound-specific intakes as described in ICH M7. The draft guidance is intended to provide guidance for new drug substances and new drug products during their clinical development and subsequent applications for marketing.
