Risk Summary
The limited available data on ELELYSO use in pregnant women are not sufficient to inform a drug-associated risk. However, there are clinical considerations [see Clinical Considerations]. In animal reproduction studies when pregnant rats and rabbits were administered taliglucerase alfa at intravenous doses up to 5 times the recommended human dose (RHD), there was no evidence of embryo-fetal toxicity [see Data]. The estimated background risk of major birth defects and miscarriage for the indicated population(s) are unknown. 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.
Clinical Considerations
Disease-Associated Maternal and/or Embryo/Fetal Risk
Women with Type 1 Gaucher disease have an increased risk of spontaneous abortion if disease symptoms are not treated and controlled pre-conception and during a pregnancy. Pregnancy may exacerbate existing Type 1 Gaucher disease symptoms or result in new disease manifestations. Type 1 Gaucher disease manifestations may lead to adverse pregnancy outcomes, including hepatosplenomegaly which can interfere with the normal growth of a fetus and thrombocytopenia which can lead to increased bleeding and possible postpartum hemorrhage requiring transfusion.
Data
Animal Data
Reproduction studies have been performed with taliglucerase alfa administered during the period of organogenesis in rats and rabbits. In rats, intravenous doses up to 55 mg/kg/day (about 5 times the RHD of 60 units/kg based on the body surface area) did not cause any adverse effects on embryo-fetal development. In rabbits, intravenous doses up to 27.8 mg/kg/day (about 5 times the RHD of 60 units/kg based on the body surface area) did not show any embryo-fetal toxicity.
Risk Summary
There are no data on the presence of taliglucerase alfa in human milk, the effects on the breast fed infant or the effects on milk production. The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for ELELYSO and any potential adverse effects on the breastfed child from ELELYSO or from the underlying maternal condition.
The safety and effectiveness of ELELYSO for the treatment of pediatric patients 4 years of age and older with a confirmed diagnosis of Type 1 Gaucher disease has been established. The use of ELELYSO for this indication is supported by evidence of effectiveness from adequate and well-controlled trials of ELELYSO in adults, with additional pharmacodynamic data from 5 pediatric patients and pharmacokinetic data from 9 pediatric patients who participated in clinical trials [see Clinical Studies (14.1, 14.2), Clinical Pharmacology (12.3)]. Data from 14 pediatric patients were included in the safety evaluation [see Adverse Reactions (6.1)]. The safety and effectiveness of ELELYSO has not been established in patients less than 4 years of age.
Pediatric patients experienced a higher frequency of vomiting during ELELYSO treatment (4 of 9 treatment-naïve patients) than adult patients, and this may be a symptom of hypersensitivity reaction. The frequencies of other adverse reactions were similar between pediatric and adult patients treated with ELELYSO [see Adverse Reactions (6.1)].
