Description

Inclusion Criteria:

  • Confirmed diagnosis of Friedreich's Ataxia (FA) by Frataxin genetic testing and/or Frataxin enzyme analysis
  • Between age 10 and 50 years of age, inclusive
  • Body weight of 25 kilograms or higher
  • Minimum of one affected organ (cardiac or neurological) system, as evidenced by clinical signs/symptoms
  • Disease duration ≤7 years, based on onset date of FA symptoms
  • Has no known contraindication to gadolinium contrast such as severe allergy or Glomerular Filtration Rate <30 ml/min/m^2.
  • Has no known contraindication to non-contrast Magnetic Resonance Imaging (MRI) evaluation such as pacemaker or magnetically active metal fragments.
  • Women of childbearing age must:

    • Have a negative pregnancy human chorionic gonadotropin test prior to receiving study drug.
    • Agree to use contraception for the duration of the study drug dosing, plus 1 month after completion of the study.

Exclusion Criteria:

  • Advanced cardiac failure, New York Heart Association (NYHA) Classification Scale-Class IV (advanced stage heart failure)
  • Clinically significant comorbidities that may also lead to cardiomyopathy, for example long standing hypertension, familial cardiomyopathy.
  • Clinically significant comorbidities that would, in the opinion of the investigators, compromise the interpretation of test results.
  • Pregnant, breast-feeding or planning to become pregnant during study timeframe.
  • Patients with contraindications to regadenoson, i. e. second- or third-degree atrioventricular (AV) block or sinus node dysfunction. Has received an investigational drug within thirty (30) days of baseline visit.
  • Thrombocytopenia (<125 x 10^9/Liter) or prolonged Prothrombin Time/Partial Thromboplastin Time (PT/PTT) at baseline.
  • Clinically significant hypotension (systolic blood pressure <90) due to heart failure or other conditions.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change From Baseline in Friedreich Ataxia Rating Scale (FARS) Composite Score
Time Frame: Baseline, 24 weeks

The Friedreich Ataxia Rating Scale (FARS) is made up of a measure of ataxia, an activities of daily living subscale and a neurological subscale. This scale also includes the 8m walk at maximum speed (8MW), the 9-hole peg test (9HPT), PATA rate (assesses speech speed by repetitions of pronouncing "PaTa" ) and low-contrast letter acuity.

FARS is made up of a measure of ataxia, an activities of daily living subscale and a neurological subscale. This scale also includes the 8m walk at maximum speed (8MW), the 9-hole peg test (9HPT), PATA rate and low-contrast letter acuity. The scores from the three subscales are added to generate a total score ranging from 0 to 159, with a higher score indicating a greater level of disability.

Baseline, 24 weeks
Change in Ventricular Hypertrophy as Shown on Cardiac MRI
Time Frame: Baseline, 24 weeks
Left ventricular mass and left ventricular (LV) mass indexed to body surface area estimated by Left Ventricle (LV)cavity dimension and wall thickness at end-diastole. Normal values of LV mass indexed to body surface area are found to be 49-115 gL/m2 in men and 43-95 g/m2 in women.
Baseline, 24 weeks
