Fasenra: which tox species, and why?
benralizumab · IL-5Rα
Species
Cynomolgus monkey only
“Pivotal nonclinical studies were conducted in Cynomolgus monkeys.”
Why that species
Binds human and cynomolgus IL-5Rα with similar affinity (KD 11 and 42 pM); no cross-reactivity with murine IL-5Rα
“Benralizumab binds to human and cynomolgus monkey IL-5Rα with KD values of 11 and 42 pM, respectively (as measured by BIAcore). Benralizumab did not cross-react with murine IL-5Rα.”
Surrogate molecule
No surrogate (mouse surrogate judged not required); the clinical antibody was tested in cynomolgus monkeys
“Further, the ECAC agreed that development of a mouse surrogate was not required.”
