Trastuzumab does not recognise rodent p185neu; monkeys bind but do not overexpress HER2
“Since trastuzumab is a humanised MAb, significant species differences in pharmacokinetics are to be expected: rodent p185neu (corresponding receptor protein to human p185HER2) is not recognised, whereas in non-human primates trastuzumab recognises a receptor (as yet uncharacterised) in epithelial cells. However, unlike humans these primate species do not overexpress p185HER2 or produce shed antigen.”
EMA: pharmacology and toxicology thoroughly examined in more than 50 studies, the large majority of very good quality
“The toxico-pharmacological properties of trastuzumab were thoroughly examined in Part III of the dossier, which comprises more than 50 studies, of which the large majority was of very good quality.”
