An Open-Label Trial to Address the Safety of the SmartFlow MR-Compatible Ventricular Cannula for Administering Eladocagene Exuparvovec to Pediatric Subjects

PTC Therapeutics·interventional·Posted May 26, 2021·Updated Apr 24, 2026

In Brief

A Phase 2 clinical trial evaluating Eladocagene Exuparvovec for AADC Deficiency. Active but no longer recruiting, targeting 13 participants across 6 sites in 3 countries.

Detailed Summary

This study will have a trial phase, extension phase, and a long-term extension phase. The primary objectives of the trial phase are to assess the pharmacodynamics (PD) of eladocagene exuparvovec treatment by evaluation of homovanillic acid (HVA) levels and to assess the safety of the SmartFlow® magnetic resonance (MR) Compatible Ventricular Cannula for administering eladocagene exuparvovec to pediatric participants with aromatic L-amino acid decarboxylase (AADC) deficiency. The extension phase is designed to capture additional clinical information for eladocagene exuparvovec through study evaluations, changes in motor development, AADC-specific symptoms, and other PD measures. The long-term extension phase is designed to capture long-term safety and efficacy data from participants treated with eladocagene exuparvovec.
