A Study to Assess the Safety and Efficacy of Vatiquinone in Participants With Friedreich Ataxia

The primary objective of this study is to assess the long-term safety of vatiquinone in participants with Friedreich ataxia (FA) previously exposed to vatiquinone.

This long-term, open-label study will serve as a continued access study for participants with FA who have previously participated in a vatiquinone study. The purpose of this study is to assess continued safety and efficacy of vatiquinone dosing in previously treated participants. This study addresses the medical need for participants to continue vatiquinone with a planned study duration of 3 years.
