About this trial

The purpose of this study is to test the safety and preliminary efficacy of AAVrh.10hFXN to treat the cardiomyopathy associated with Friedreich's ataxia (FA). AAVrh.10hFXN is a serotype rh.10 adeno-associated virus gene transfer vector coding for Frataxin (FXN). The drug is administered intravenously. This is a phase 1, open label, dose escalation study with a total of 25 participants.

Eligibility criteria

Qualifiers

Males and females, age 12 to 50

Willing and able to provide informed consent

Definitive diagnosis of FA, based on clinical phenotype and genotype (GAA expansion on both alleles)

>600 GAA repeats in intron 1 in at least one allele

Disqualifiers

Individuals receiving corticosteroids or other immunosuppressive medications

Individuals with uncontrolled diabetes (glycated hemoglobin, HbA1c levels >7%)

Genotype FA missense mutation on one or both alleles

Evidence of infection defined by elevated white blood cell count, temperature >38.5̊ C, infiltrate on chest x-ray
