NCT ID NCT03856203
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study followed 12 adults with PKU to see how their nutrition changed before and during treatment with pegvaliase (Palynziq). Researchers measured protein intake, body composition, bone density, and vitamin levels over 15 months. The goal was to understand if the drug affects nutritional health, not to test its effectiveness.
