“The toxicology package submitted by the applicant comprised studies in a single species (cynomolgus monkey) using the intended clinical routes of administration (intravenous and subcutaneous).”
Cynomolgus IL-23 binding similar to human (55 pM); rabbit >1000-fold lower; no mouse or rat binding
“Similar binding kinetics were demonstrated for cynomolgus monkey IL-23 with a calculated value of 55 pM, however, the binding affinity for rabbit IL-23 was > 1000 fold lower and no binding to mouse or rat IL-23 was detectable.”
