Brigatinib (Alunbrig) (MW 584) is given orally for the treatment of metastatic non–small-cell lung cancer. In rats, doses less than or slightly above the human exposure caused multiple anomalies in the fetuses of pregnant rats. Copanlisib (Aliqopa) (MW 553) is a kinase inhibitor that is given intravenously for relapsed follicular lymphoma. In rats during organogenesis, doses based on body surface area that were a fraction of the human dose caused embryo-fetal death and fetal defects. Durvalumab (Imfinzi) (MW 146,000), given intravenously, is indicated for the treatment of metastatic urothelial carcinoma and non–small-cell lung cancer. Monkeys given the drug from organogenesis through delivery experienced increased premature birth, fetal loss, and premature neonatal death. Women of reproductive potential should use effective contraception during treatment and for at least 3 months after the last dose.
Enasidenib (Idhifa) (MW 569), given orally, is indicated for the treatment of myeloid leukemia. The drug caused maternal toxicity and adverse embryo-fetal effects (postimplantation loss, resorptions, decrease viable fetuses, lower fetal birth weights, and skeletal variations) in rats and spontaneous abortions in rabbits. Inotuzumab ozogamicin (Besponsa) (MW 160,000), given intravenously, is indicated for relapsed or refractory B-cell precursor acute lymphoblastic leukemia. The drug caused fetal harm in rats but not in rabbits. Midostaurin (Rydapt) (MW 571) is an oral kinase inhibitor indicated for myeloid leukemia. In rats, a dose given during the first week of pregnancy that was a small fraction of the human exposure caused pre- and postimplantation loss. When very small doses were given during organogenesis to rats and rabbits there was significant maternal and fetal toxicity.
Neratinib (Nerlynx) (MW 673) is an oral kinase inhibitor for breast cancer. Although the drug did not cause embryo-fetal toxicity in rats, it did cause this toxicity in rabbits. Doses that resulted in exposures that were less than the human exposure caused maternal toxicity, abortions, and embryo-fetal death. Lower doses caused multiple fetal anomalies. Niraparib (Zejula) (MW 511) is indicated for treatment of epithelial ovarian, fallopian, or peritoneal cancer. Because of the potential human embryo-fetal risk based on its mechanism of action, pregnant animal studies were not conducted. Women with reproductive potential should use effective contraception during treatment and for 6 months after the last dose. Ribociclib (Kisqali) (MW 553) is an oral kinase inhibitor indicated for postmenopausal women with breast cancer. In rats, the drug cause reduced fetal weights and skeletal changes. Increased incidences of fetal abnormalities and lower fetal weights were observed in rabbits.
Angiotensin II (Giapreza) (MW 1,046) is a naturally occurring peptide hormone given as an intravenous infusion. It is indicated as a vasoconstrictor to increase blood pressure in adults with septic or other distributive shock. Animal reproduction studies have not been conducted. Because septic or other distributive shock is a medical emergency that can be fatal, the use of this agent in pregnancy should not be withheld.
