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 first portion will evaluate two 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.
