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

Summary

This study tests a one-time gene therapy called ECUR-506 in baby boys under 9 months old with a severe form of OTC deficiency, a genetic disorder that prevents the body from breaking down ammonia. The goal is to see if the treatment is safe and can reduce dangerous ammonia levels, potentially allowing babies to stop taking daily medications. The trial involves up to 20 participants and will monitor for side effects and effectiveness over time.
