Luxturna: which tox species, and why?
voretigene neparvovec · RPE65
Species
Dog (normal-sighted and RPE65-mutant Briard) and non-human primate
“Single dose and repeat dose toxicology studies were conducted in normal-sighted dogs, RPE65 mutant dogs, and normal-sighted non-human primates (NHPs).”
Why that species
RPE65-/- Briard dog is a natural large-animal disease model; eye size makes dog more relevant than mouse
“The applicant noted that relative transduction efficiency of AAV2 in RPE cells across species is not known but that, given the sizes of eye in dog and mouse, the studies in Briard dogs are more relevant to human effects than those in mice”
Surrogate molecule
Yes: precursor vector AAV2-hRPE65v1 (low RPE65 expression) used in GLP dog studies; clinical vector in NHP and re-dosing studies
“Thus, any potential toxicity due to the RPE65 protein cannot be adequately assessed using this vector construct.”
