Korjuny: which tox species, and why?

catumaxomab · EpCAM x CD3
Species
No relevant species; limited single-dose mouse, rat, one cynomolgus; BiLu mouse surrogate
“None of the animal species analysed is suitable for assessing the safety of catumaxomab.”
✓ VerifiedEMA assessment report, p. 37Source ↗
Why that species
No binding to cells from rodents, rabbit, dog or NHPs; CD3/EpCAM binding human-specific
“None of the studies demonstrated binding of catumaxomab to cells from non-clinical species.”
✓ VerifiedEMA assessment report, p. 37Source ↗
Surrogate molecule
Yes: BiLu (anti-human EpCAM x anti-mouse CD3) in mice; only partially reflects catumaxomab
“Since BiLu recognises only murine CD3 but not murine EpCAM, the surrogate mAb only partially reflects the functionality of catumaxomab.”
