Onpattro: which tox species, and why?
patisiran · TTR (siRNA)
Species
Rat and cynomolgus monkey (monkey pharmacologically active; rat off-target/LNP)
“As a consequence, general toxicology studies have been performed in cynomolgus monkeys (pharmacologically active) and rats (off-target).”
Why that species
siRNA sequence cross-reacts with cynomolgus TTR but not rat, mouse or rabbit
“Patisiran is a siRNA directed against human TTR mRNA and has cross-reactivity in the cynomolgus monkeys, but not in rat mouse or rabbit.”
Surrogate molecule
Yes: rodent-specific surrogate siRNA-LNP (AF-011-18534) in rat DART; luciferase-siRNA LNP control in general tox
“To evaluate on-target reproductive and developmental toxicities related to siRNA- mediated reduction in serum TTR concentrations (TTR reduction and associated reductions in vitamin A and thyroxine) the rodent reproductive and developmental toxicity studies included a rodent surrogate siRNA (AD-18534).”
