Species: DART
Rat and rabbit (EFD); fertility and pre/postnatal studies not conducted (not required for indication)
“Dedicated studies to assess vorasidenib-related effects on fertility and pre- and postnatal development were not conducted, as these evaluations are not required for the current indication. Effects were observed on reproductive organs in male and female rats during 28-day and 13-week repeat-dose toxicity studies. Embryo-fetal development (EFD) studies were conducted in gravid rats and rabbits.”
