NCT ID NCT05579548
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study follows 50 pregnant women with phenylketonuria (PKU) who have taken the drug Palynziq (pegvaliase) around the time of pregnancy or while breastfeeding. Researchers will track pregnancy outcomes and infant health, including birth defects and development. The goal is to gather real-world safety data, not to test a new treatment.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Pegvaliase (Palynziq)
What this could lead to
If successful, this study could provide crucial safety information for pregnant women with PKU who need Palynziq, helping doctors and patients make informed decisions.
What could go wrong
This is an observational study, not a controlled trial, so it cannot prove cause and effect. The small size (50 participants) limits how much we can learn, and results may not apply to all patients.
