Residual impurities resulting from the synthetic route, the formulation, or from degradation of the active drug and/or the excipients, may be present in the pharmaceutical products that will be administered to patients. Some of these impurities may present a potential for genotoxicity and therefore pose an additional safety concern to clinical subjects and patients. When genotoxic impurities are detected, these should be controlled and limited, if not avoided, in the final product to ensure the safety of the patients. During drug development, the strategies to control all impurities at safe concentrations are mandatory and regulated by ICH guidelines that are adopted worldwide. However, the effort made to limit impurities must be commensurate with the risk assessed at each phase of clinical development and thereafter for marketing. The webinar provides a general overview of the topic of genotoxic impurities and the approaches to safety evaluations.

Why Should You Attend

An effective evaluation of potential genotoxic impurities is essential for the overall success of any drug development program for small molecules. In this webinar expert speaker Stefano Persiani will focus on the basics for an effective genotoxic impurities assessment. A case study will be described to further provide focus on the concepts discussed.
