EPI-743 in Friedreich's Ataxia Point Mutations

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to evaluate the effects of EPI-743 in patients with Friedreich's Ataxia point mutations

Detailed Description
-----------------
The primary objective of this study is to investigate whether treatment with EPI-743 has a discernible impact on visual function-including visual acuity, visual fields and color vision as well as on any of a number of functional and subject/clinician-rated scales relevant in the treatment of Friedreich's ataxia, and to determine the safety of treatment with EPI-743.

Official Title
-----------------
A Phase 2A Clinical Trial of EPI-743 (Vincerinone™) on Visual Function in Friedreich's Ataxia Patients With Point Mutations

Conditions
-----------------
Friedreich's Ataxia

Intervention / Treatment
-----------------
* Drug: EPI-743

Abstention from use of dietary supplements and non-prescribed medications at least 30 days prior to initiation of treatment and for the duration of the study. This would specifically include idebenone, Coenzyme Q10 and vitamin E. Abstention from foods or beverages or bars fortified with Coenzyme Q10, vitamin E, super fortified functional foods or beverages at least 30 days prior to initiation of treatment and for the duration of the study. Abstention from use of other investigative or non-approved drugs within 30 days of enrollment and for the duration of the study. Subject can swallow multiple size 0 capsules. Subject has voluntarily signed an IRB approved informed consent form to participate in the study after all relevant aspects of the study have been explained and discussed with the subject. Exclusion Criteria: Allergy to EPI-743 or sesame oil or nuts. Clinically significant bleeding condition or abnormal PT/PTT INR (INR > two; PTT > two-times normal). Liver insufficiency with LFTs greater than three-times upper normal limit at screening. Renal insufficiency with creatinine > 1.5 at screening. Fat malabsorption syndromes. Any other respiratory chain diseases of the mitochondria or inborn errors of metabolism. Any other ophthalmologic conditions. Clinically significant cardiomyopathy with ejection fraction < 40 percent at screening. Clinically significant arrhythmia within past two years requiring treatment. Surgery planned through the duration of the study, including follow-up. Pregnancy or breastfeeding. Anticoagulant therapy within 30 days of enrollment.
