“In line with the guideline on the pre-clinical safety evaluation of biotechnology-derived pharmaceuticals (ICH S6 R1), no genotoxicity studies were carried out.”
Not conducted; rodent studies not feasible (no binding to rodent TSLP); carcinogenicity risk assessment conducted
“The conduct of carcinogenicity studies in rodents was not feasible as tezepelumab does not bind to rodents’ TSLP. Therefore, a carcinogenicity risk assessment was conducted.”

Monkey ePPND (IV 50 or 300 mg/kg Q7D, early gestation through delivery): no maternal, fetal or infant effects
“In the maternal, embryo-fetal, and neonatal toxicity (ePPND) study, pregnant female cynomolgus monkeys were dosed Q7D at 50 or 300 mg/kg IV from early gestation through delivery. There were no tezepelumab-related effects (maternal, fetal, or infant).”
Single-dose IV monkey study up to 300 mg/kg: no effect on hemodynamics, body temperature, respiration, ECG or neurobehavior
“In an in vivo safety pharmacology study conducted in the cynomolgus monkey, single dose IV injection of tezepelumab up to 300 mg/kg did not affect hemodynamic parameters, body temperature, respiration rate, ECG, or neurological behavior.”
