  • 1.  DEREK analysis

    Hi,

    When the report of DEREK says that we have alert for Chromosome damage, should we consider the compound as Genotoxic. 
    or should we consider it to be genotoxic only if we have alerts for mutagenicity.

    For purposes of ICH M7, only mutagenicity is considered - not the broader genotoxicity.
       Remember, however, that two QSAR methods (one expert - such as Derek - and one statixstical are required to qualify an impurity for this endpoint/M7 complance.
