Rat and rabbit EFD: embryofetal mortality, growth alterations and malformations below human exposure
“In animal embryo-fetal development studies, oral administration of dordaviprone to pregnant rats and rabbits during the period of organogenesis caused embryofetal mortality, alterations to growth, and structural abnormalities at exposures below the human exposure at the highest recommended dose”
“Dordaviprone inhibited hERG potassium channel current with an IC50 of 2.4 µM in an in vitro safety pharmacology assessment. No changes were noted in ECG parameters in dogs”
