EPI-743 in Friedreich's Ataxia Point Mutations

Phase 2
Completed
Conditions
Friedreich's Ataxia
Interventions
Registration Number
NCT01962363
Lead Sponsor
University of South Florida
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.
