What this Trial Is About

This research aims to observe the effects of Palynziq (pegvaliase) treatment in pregnant women with phenylketonuria (PKU) and on their babies exposed to pegvaliase during pregnancy and breastfeeding. The study is a Phase 4 observational trial that evaluates maternal, fetal, and infant outcomes related to pegvaliase exposure. It includes women diagnosed with PKU who were treated with pegvaliase from two weeks before their last menstrual period (LMP) or at any time during pregnancy. Participants are pregnant women prescribed pegvaliase by their healthcare provider who enroll through a centralized call center. The study collects data retrospectively from at least three months before the LMP, through pregnancy, and during the infant's first year of life. The timing and duration of pegvaliase exposure during pregnancy and breastfeeding, including each trimester, are recorded. Individual participation lasts up to about 21 months. During the study, information will be gathered from the participant's healthcare providers and the infant's doctors. Researchers will monitor pregnancy outcomes and infant development over ten years, focusing on pegvaliase exposure effects. The study also tracks serious adverse events and pegvaliase use during breastfeeding. This long-term monitoring aims to provide detailed data on maternal and infant health following pegvaliase exposure.
