Rat (repeat-dose) and cynomolgus monkey (single-dose safety pharmacology)
“Animal studies exploring the safety of dinutuximab were conducted in Sprague Dawley rats and cynomolgus monkeys.”

Why that species
Antibody binds GD2 in rats and lowers mechanical pain thresholds; TCR staining consistent with GD2 expression in rat and rabbit
“Though there were no histopathological indications of an effect of dinutuximab on peripheral nerves in this study, ch14.18 has been shown to bind to GD2 in rats.”

Surrogate molecule
No surrogate; the clinical antibody was tested in rats and cynomolgus monkeys

Species: DART
Not conducted: not required for paediatric population (90% under 5 years)
“Based on the median age of the proposed patient population (90% of patients less than 5 years of age), the Agency agreed that reproductive and developmental toxicology studies would not be required to support the BLA for Unituxin for the treatment of high risk neuroblastoma.”

Pharmacology literature also used surrogate antibodies with murine constant regions; toxicology used dinutuximab
“The pharmacologic characterization of dinutuximab is based on published literature detailing experiments using ch14.18 and surrogate antibodies with the same variable domain but with alternative murine constant regions.”
