Gene Therapy for Cardiomyopathy Associated With Friedreich's Ataxia
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.
detailed description
Friedreich's ataxia (FA) is a rare, autosomal recessive disease caused by a mutation in the autosomal frataxin (FXN) gene. Progressive cardiomyopathy with cardiac hypertrophy and fibrosis is observed in most individuals with FA. The disease is more severe in those with earlier onset. Presently, there is no therapy that alters the progression of cardiomyopathy in FA, which is responsible for 59% of FA-related deaths.
The primary objective of this dose escalation study is to assess the safety and tolerability of three ascending doses of LX2006 in patients with FA-associated cardiomyopathy. LX2006 is designed to restore hFXN levels in order to improve mitochondrial function. Assessments of cardiac function, biomarkers and other preliminary efficacy endpoints are also included in this study.
