Monkey EFD: embryolethality and abortions at 1.25-5x human dose, no teratogenicity
“There were no fetal malformations or other evidence of teratogenesis noted in the offspring; however, significant increases in embryolethality and abortions occurred at doses of approximately 1.25 to 5 times the recommended human dose (based on body weight).”
Single-dose monkey telemetry study (CV, respiratory, CNS): no clinical signs, no CNS or respiratory effects, no ECG effects
“In this study, no clinical signs related to panitumumab were observed. Neuro-behavioural tests did not reveal any effect on the central nervous system.”
