Tysabri: which tox species, and why?

natalizumab · α4-integrin
Species
Cynomolgus monkey (repeat-dose); guinea pig and monkey for reproductive toxicity
“Two cross-reactive species, the cynomolgus monkey and guinea pigs were used to”
✓ VerifiedEMA assessment report, p. 10Source ↗
Why that species
Antibody binds cynomolgus/rhesus, guinea pig, dog, pig and ferret lymphocytes; no binding to rat, hamster, rabbit or marmoset
“The following species are reacting with the antibody: Rhesus and cynomolgus monkey, pig, ferret, guinea pig, and dog. Lymphocytes from rat, gerbil, hamster, rabbit, or marmoset monkey are not reactive.”
✓ VerifiedEMA assessment report, p. 7Source ↗
Surrogate molecule
No surrogate; the clinical antibody was tested in cynomolgus monkeys and guinea pigs; rodents not used
“Standard but pharmacologically irrelevant, rodent species were not evaluated.”
