The investigational gene therapy involves a single, intravenous administration of a modified adeno-associated virus that delivers the normal FXN gene to the heart (and other organs). The goal of this initial clinical study is to assess safety and initial estimates of efficacy in treating heart disease.

Participation in this study requires an overnight stay at The New York Presbyterian Hospital/Weill Cornell Medicine for observation after administration of the study drug, followed by a one week stay at the Hemsley Hotel on the Weill Cornell Medical campus. Participants will then be assessed periodically over 5 years including 4 visits to the study site at Weill Cornell Medical campus at 1, 3, 6, and 12 months following administration of the study drug.

This clinical trial is funded by the National Heart, Lung, and Blood Institute at no cost to participants including travel and accommodation expenses.

  • Left ventricle ejection fraction (EF) measured by cardiac MRI of >45% to 70%
  • In the absence of other factors known to cause left ventricular hypertrophy (LVH), left ventricular mass index on cardiac MRI >2 standard deviations above the normal range
  • Stroke volume index (<45 mL/m2) and/or global longitudinal left ventricular strain (<20%) on cardiac MRI
  • <5% fibrosis in the left ventricular wall on late gadolinium enhancement cardiac MRI
  • Serum neutralizing anti-AAVrh.10 titer <1:40
  • Capable of undergoing cardiac MRI

Exclusion Criteria:
 
  • 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
  • Contraindication to cardiac MRI (e.g., non-MRI compatible pacemaker/defibrillator) or gadolinium
  • Any malignancy during the last five years, except basal cell skin cancer
  • Prior participation in any gene and/or cell therapy
