Pasatru: which tox species, and why?
garetosmab · Activin A
Species
Rat and cynomolgus monkey
“repeat dose toxicology studies in rats up to 5 weeks and cynomolgus monkeys up to 27 weeks, reproductive and developmental toxicity studies in cynomolgus monkeys”
Why that species
Not stated in public reviews
The reviews list the species but not why. For biologics, ICH S6(R1) asks for species in which the product is pharmacologically active (target binding and activity), usually a cynomolgus monkey.
“A relevant species is one in which the test material is pharmacologically active due to the expression of the receptor or an epitope (in the case of monoclonal antibodies).”

Surrogate molecule
No surrogate; the clinical antibody was tested in rats and cynomolgus monkeys
“repeat dose toxicology studies in rats up to 5 weeks and cynomolgus monkeys up to 27 weeks, reproductive and developmental toxicity studies in cynomolgus monkeys”
