The existing guideline on toxicology studies applicable to RP “ICH guideline M3(R2) on non-clinical safety studies for the conduct of human clinical trials and marketing authorisation for pharmaceuticals” (CPMP/ICH/286/95) leaves some room for interpretation and is not always clear in describing the type of toxicology study required for various RP applications. Other preclinical toxicity and/or safety studies that are part of an IND are genotoxicity, reproductive toxicity, and carcinogenicity. This guidance represents the Food and Drug Administration’s (FDA’s) current thinking on this topic. • Preclinical studies are designed to support use of a specific product for a specific clinical indication • Identification of biologically relevant dose levels to guide clinical dose levels. New regulatory guidance documents from the United States Food and Drug Administration (FDA) and the European Medicines Agency (EMA) have recently been finalized or are in draft format outlining new pathways for preclinical safety testing. sufficient guidance from the FDA on new small molecules and biological products as to which preclinical studies are to be conducted.
