zenocutuzumab · HER2 x HER3Not conducted (ICH S6(R1))
Kimmtrak: genotox, carcinogenicity and repro: done or skipped?
tebentafusp · CD3 x gp100 (TCR fusion)
Genotoxicity
Not conducted (fusion protein; ICH S6/S9)
“Based on the biologic properties of tebentafusp, a fusion protein, genetic toxicology studies are not warranted.”
Carcinogenicity
Not conducted (advanced cancer indication)
“Carcinogenicity studies were not warranted for the proposed indication.”
Reproductive & developmental
Not conducted (no relevant species); weight-of-evidence; FDA concluded possible fetal harm to skin, inner ear, eye
“Due to the specificity for human targets, embryo-fetal development (EFD) studies cannot be conducted in nonclinical species. Therefore, a weight of evidence assessment was conducted to evaluate the risk of tebentafusp administration on pregnancy and embryo-fetal development.”
Safety pharmacology
Not conducted (no relevant species; in vitro only)
“Therefore, no specific safety pharmacology studies were conducted.”
