Ibrexafungerp Pregnancy Warnings

Animal studies have revealed evidence of fetal malformations; after administration via oral gavage to pregnant rabbits during organogenesis (at dose exposures greater or equal to about 5 times the human exposure at the recommended human dose [RHD] based on AUC comparison), rare malformations (including absent forelimb[s], absent hindpaw, absent ear pinna, and thoracogastroschisis) were observed. In rabbits, fetal malformations (including absent ear pinna, craniorachischisis, thoracogastroschisis, trunk kyphosis, absent forelimbs, absent forepaws, and absent hindpaw) occurred at about 5 times the RHD (based on AUC comparison) in a single fetus, while malformations (including absent hindpaw and anencephaly) occurred with an increased litter incidence at about 13 times the RHD (based on AUC comparison) and other malformations occurred in single fetuses and litters (absent ear pinna, thoracogastroschisis, absent forelimb, absent thyroid gland); no changes in embryofetal survival or fetal body weights were seen at any dose and no fetal malformations were observed at about 2 times the RHD (based on AUC comparison). After administration via oral gavage to pregnant rats during organogenesis (at dose exposures up to about 5 times the human exposure at the RHD based on AUC comparison), no fetal malformations, changes in embryofetal survival, or changes in fetal body weights occurred. There are no controlled data in human pregnancy.
