However, ICH M7 focuses only on one genotoxicity endpoint (gene mutation) and one test (Ames test). But different contexts and regulations exist.
WebGene mutation test in bacteria. In vivo genotoxicity assessment with two different tissues, usually an assay for micronuclei using rodent hematopoietic cells and a second in vivo assay. Typically, this would be a DNA strand breakage assay in liver, unless otherwise justified. (Can be integrated into repeat tox studies if a suitable dose is used.) WebFor linkers, it is important to determine if exposure to reactive forms are likely to occur and from which origin. When the linkers are anticipated to be potential mutagenic …
