“The repeated-dose toxicity evaluation of trastuzumab is based on a four-week study in rhesus monkeys and 12- and 26-week studies in cynomolgus monkeys.”
Monkey HER2 recognized (high homology, similar tissue binding); rodent p185neu not recognized
“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.”
Yes: surrogate antibody specific for rat c-erbB2, used for rat doxorubicin cardiotoxicity model
“Enhanced cardiotoxicity was not observed in a rat model of doxorubicin cardiotoxicity following addition of a surrogate antibody specific for rat c-erbB2.”
