Brief Summary:
This 24-week study will test the safety and effectiveness of synthetically produced (+) Epicatechin in treating patients who have Friedreich's Ataxia, a neurological disorder.

Condition or disease Intervention/treatment Phase
Friedreich's Ataxia Drug: (+)-Epicatechin Phase 2

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 10 participants
Allocation: N/A
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Phase II, Open Label Prospective Single Center Drug Study Evaluating the Safety and Efficacy of (+)-Epicatechin in Subjects With Friedreich's Ataxia
Study Start Date : September 2016
Actual Primary Completion Date : December 30, 2018
Actual Study Completion Date : December 30, 2018

Arm Intervention/treatment
Experimental: (+)-Epicatechin
Total daily dose 75mg (+)-Epicatechin; 25mg cap three times per day by mouth for 24 weeks
Drug: (+)-Epicatechin
25mg (+)-Epicatechin capsules. Starting dose 75mg total daily dose (one 25mg cap taken three times per day). Dose escalation at 12 weeks for non-responders to 150mg total daily dose (two 25mg caps taken three times per day)

Primary Outcome Measures :
  1. 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.

  2. 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.
