Gene Therapy for Cardiomyopathy Associated With Friedreich's Ataxia

About

Brief Summary

This is a Phase 1/2, open-label, dose-ascending, multicenter study of the safety and efficacy of LX2006 for participants who have Friedreich's Ataxia with evidence of cardiomyopathy. The study will evaluate up to three doses of single administration of LX2006 (AAVrh.10hFXN), an adeno-associated virus (AAV) gene therapy designed to intravenously deliver the human frataxin (hFXN) gene to cardiac cells over a 52-week period. Long-term safety and efficacy will be evaluated for an additional 4-years for a total of 5-years post LX2006 treatment.
