Offspring toxicity in rat pre/postnatal study at low exposure multiples
“The findings in the pre- and postnatal development study in rats as described above appear to be clinically relevant, based on the low multiples (0.6 to 4.9) of the human AUC that produced adverse effects in the offspring, which included stillbirths, mortality, and reduced bodyweight.”
