Acalabrutinib Pregnancy Warnings

In one animal study, drug administration at doses approximately 4 times the AUC in patients at the recommended human dose (RHD) produced maternal toxicity and resulted in decreased fetal body weights and delayed skeletal ossification. In another animal study, drug administration at doses approximately 16 times the AUC in patients at the RHD produced no effects on embryo-fetal development and survival. An animal fertility study demonstrated no fertility effects in both females and males at exposures 16 to 18 times the AUC in patients at the RHD. There are no controlled data in human pregnancy.
