One-Time gene fix could ease PKU's strict diet burden

NCT ID NCT06332807

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This early-stage trial tests a gene therapy called NGGT002 for adults with classic PKU, a genetic disorder that makes it hard to break down an amino acid called phenylalanine. The treatment delivers a working copy of the missing gene via a single IV infusion. Researchers will monitor 12 participants for 5 years to check safety and whether blood phenylalanine levels drop enough to relax the strict diet.
