(zavegepant)
Risk Summary
There are no adequate data on the developmental risk associated with the use of ZAVZPRET in pregnant women. No adverse developmental effects were observed following subcutaneous administration of zavegepant to pregnant animals at doses associated with plasma exposures higher than those used clinically (see Data).
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. The estimated rate of major birth defects (2.2 to 2.9%) and miscarriage (17%) among deliveries to women with migraine are similar to rates reported in women without migraine.
Clinical Considerations
Disease-Associated Maternal and/or Embryo/Fetal Risk
Published data have suggested that women with migraine may be at increased risk of preeclampsia and gestational hypertension during pregnancy.
Animal Data
Subcutaneous administration of zavegepant to pregnant rats (0, 10, 20, or 40 mg/kg/day) or rabbits (0, 20, 40, or 60 mg/kg/day) during the period of organogenesis resulted in no adverse effects on embryofetal development. Plasma exposures (AUC) at the highest doses tested were approximately 4000 times that in humans at the maximum recommended human dose (MRHD) of 10 mg/day.
Subcutaneous administration of zavegepant (0, 5, 10, or 20 mg/kg/day) to rats throughout pregnancy and lactation resulted in no adverse effects on pre- and postnatal development. Plasma exposure (AUC) at the highest dose tested was approximately 2500 times that in humans at the MRHD.
There are no data on the presence of zavegepant or its metabolites in human milk, the effects of zavegepant on the breastfed infant, or the effects of zavegepant on milk production. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for ZAVZPRET and any potential adverse effects on the breastfed infant from ZAVZPRET or from the underlying maternal condition.
Clinical studies of ZAVZPRET did not include sufficient numbers of patients 65 years of age and older to determine whether they respond differently from younger adult patients.
In a limited number of patients 65 years of age and older, no clinically significant pharmacokinetic differences were observed between elderly and younger subjects.
No dosage adjustment of ZAVZPRET is necessary in patients with mild hepatic impairment (Child-Pugh Class A) or moderate hepatic impairment (Child-Pugh Class B). ZAVZPRET has not been studied in patients with severe hepatic impairment (Child-Pugh Class C). Avoid use of ZAVZPRET in patients with severe hepatic impairment [see Clinical Pharmacology (12.3)].
No dosage adjustment of ZAVZPRET is necessary in patients with estimated creatine clearance (CLcr) 30 mL/min or greater. Avoid use of ZAVZPRET in patients with CLcr less than 30 mL/min [see Clinical Pharmacology (12.3)].
