Use In Pregnancy & Lactation
Pregnancy: Risk Summary: Based on findings from animal studies and its mechanism of action, VIZIMPRO can cause fetal harm when administered to a pregnant woman [see Pharmacology: Pharmacodynamics: Clinical Studies under Actions]. There are no available data on VIZIMPRO use in pregnant women. In animal reproduction studies, oral administration of dacomitinib to pregnant rats during the period of organogenesis resulted in an increased incidence of post-implantation loss and reduced fetal body weight at doses resulting in exposures near the exposure at the 45 mg human dose (see Data as follows). The absence of EGFR signaling has been shown to result in embryolethality as well as post-natal death in animals (see Data). Advise pregnant women of the potential risk to a fetus [see Females and Males of Reproductive Potential as follows].
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: Daily oral administration of dacomitinib to pregnant rats during the period of organogenesis resulted in an increased incidence of post-implantation loss, maternal toxicity, and reduced fetal body weight at 5 mg/kg/day (approximately 1.2 times the exposure based on area under the curve [AUC] at the 45 mg human dose).
Disruption or depletion of EGFR in mouse models has shown EGFR is critically important in reproductive and developmental processes including blastocyst implantation, placental development, and embryo-fetal/post-natal survival and development. Reduction or elimination of embryo-fetal or maternal EGFR signaling in mice can prevent implantation, and can cause embryo-fetal loss during various stages of gestation (through effects on placental development), developmental anomalies, early death in surviving fetuses, and adverse developmental outcomes in multiple organs in embryos/neonates.
Lactation: Risk Summary: There is no information regarding the presence of dacomitinib or its metabolites in human milk or their effects on the breastfed infant or on milk production. Because of the potential for serious adverse reactions in breastfed infants from VIZIMPRO, advise women not to breastfeed during treatment with VIZIMPRO and for at least 17 days after the last dose.
Females and Males of Reproductive Potential: Pregnancy Testing: Verify the pregnancy status of females of reproductive potential prior to initiating VIZIMPRO [see Pregnancy as previously mentioned].
Contraception: VIZIMPRO can cause fetal harm when administered to a pregnant woman [see Pregnancy as previously mentioned].
Females: Advise females of reproductive potential to use effective contraception during treatment with VIZIMPRO and for at least 17 days after the final dose.
