Pregnancy & Breastfeeding
8.1. Pregnancy Risk Summary Based on findings in animal studies and its mechanism of action, FRUZAQLA can cause fetal harm when administered to a pregnant woman. In an embryo-fetal developmental study in pregnant rats, oral administration of fruquintinib during the period of organogenesis resulted in teratogenicity and embryo lethality at exposures below the clinical exposure (see Data ) . There are no data on the use of FRUZAQLA in pregnant women. Advise pregnant women of the potential risk to a fetus. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively. Data Animal Data In an embryo-fetal developmental study in pregnant rats, daily oral administration of fruquintinib at doses ≥0.1 mg/kg [approximately 0.2 times the recommended clinical dose of 5 mg based on body surface area (BSA)] during the period of organogenesis resulted in fetal external (edema and head and tail abnormalities), visceral, and skeletal malformations. At doses of 0.25 mg/kg (approximately 0.5 times the recommended clinical dose of 5 mg based on BSA), an increase in post-implantation loss and reduction in live fetuses was observed.
