Negative in Ames, in vitro TK6 micronucleus and rat bone marrow micronucleus assays
“ZYCUBO was not mutagenic or clastogenic in a standard battery of genotoxicity tests [bacterial mutagenicity (Ames), micronucleus assay in TK6 cells (in vitro) , and rat bone marrow micronucleus assay (in vivo)] .”
Not conducted (limited life expectancy in Menkes disease, ICH S1A waiver)
“Rodent carcinogenicity studies have not been conducted with CuHis. The limited life expectancy associated with classical MD is consistent with the International Council for Harmonisation S1A guidance criteria for waiving the requirement for carcinogenicity studies.”
Not conducted; DART studies waived as Menkes disease affects predominantly male infants
“DART studies, including FEED, EFD, and PPND studies to evaluate the reproductive toxicity potential of CuHis in patients with MD can be waived as MD manifests predominantly in male infants.”
Not genotoxic overall: Ames negative; in vitro chromosome aberration positive without (not with) metabolic activation; rat micronucleus and comet negative
