Streamlining ICH M7 analyses with an implemented protocol

A major focus of our work over the last few years has been on the development and publication of in silico toxicology protocols, discussed in previous blog posts1. This has resulted in a paper outlining a framework for such protocols2  as well as two published protocols in the areas of genetic toxicology3 and skin sensitization4. …

Establishing potency categories for Nitrosamine impurities

Nitrosamine impurities currently belong to a “cohort of concern” because of their potential to be potent mutagenic carcinogens, as described in the ICH M7 guideline1. They are also coming under increasing regulatory scrutiny with the US Food and Drug Administration and European Medicines Agency recently issuing new guidelines2,3 for examination of this class. These guidelines …

Can the burden on industry and regulators be reduced?

About 6 years ago, the International Conference on Harmonization (ICH) published the M7 guideline “Assessment and Control of DNA reactive (mutagenic) Impurities in Pharmaceuticals to limit Potential Carcinogenic Risk”.[1] This was a landmark moment for computational toxicology, as it was the first time such methods were recognized by the ICH as a regulatory test. An …
