Reproductive & developmental
Not conducted: no fertility studies (advanced cancer); EFD not requested as patients are mainly ≤5 years old
“Y-mAbs did not conduct dedicated studies to assess fertility or carcinogenicity and these studies are not warranted to support the development of a drug intended to treat patients with advanced cancer. In addition, because the age of the proposed patient population is primarily ≤5 years old, FDA did not request an embryo-fetal development study to support the use of naxitamab.”

Safety pharmacology
No stand-alone studies (advanced cancer); CV, CNS and respiratory endpoints included in general toxicity studies
“FDA agrees that stand-alone safety pharmacology studies are not expected for an antibody intended for the treatment of patients with advanced cancer. In general cardiovascular, CNS, and respiratory safety endpoints are included in general toxicity studies.”
