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.

Interventions

EPI-743 (alpha-tocotrienol quinone) is a small molecule therapeutic that was rationally designed to replete reduced glutathione through NQO1-catalyzed electron transfer from NADPH.
