Carcinogenicity
Not conducted (ICH S6; advanced cancer, ICH S9)
“According to ICH S6 (R1) guideline standard carcinogenicity bioassays are generally not appropriate for biotechnology derived pharmaceuticals and according to ICH S9 carcinogenicity studies are not warranted to support marketing for therapeutics intended to treat patients with late stage or advanced cancer.”
Monkey EFD: fetal lethality at loading doses ≥30 mg/kg then ≥10 mg/kg bi-weekly (0.2-2x human exposure)
“Pertuzumab caused fetal lethality in pregnant monkeys treated with loading doses of ≥ 30 mg/kg followed by bi-weekly doses ≥ 10 mg/kg (approximately 0.2 to 2-fold greater than the exposure at the recommended human dose, by AUC).”
