Brief Summary:
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 in Study PTC743-NEU-003-FA (NCT04577352) or Study PTC743-NEU-005-FA.

Condition or disease Intervention/treatment Phase
Friedreich Ataxia Drug: Vatiquinone Phase 3

Detailed Description:
Treatment will continue until the participant withdraw consent, regulatory authority and/or PTC discontinue the study, participant's condition substantially worsens after initiating vatiquinone treatment in this study, investigator withdraws the participant from vatiquinone treatment, if, in the investigator's clinical judgment, it is not in the participant's best interest to continue, or vatiquinone becomes commercially available in a participant's country.

Arm Intervention/treatment
Experimental: Vatiquinone
Participants with FA who were previously treated with vatiquinone at an investigational site and completed participation in a prior PTC Therapeutics (PTC)-sponsored clinical study (PTC743-NEU-003-FA or PTC743-NEU-005-FA) will continue to receive the same dose/formulation of vatiquinone (unless there has been a change in age and/or weight that meets the criteria for a different dose/formulation as described below; dose/formulation will also be changed if participants meet the criteria for a different dose/formulation during study treatment): If <7 years of age, participants will receive an oral solution (100 milligrams [mg]/milliliter [mL]) 3 times a day (TID) at one of the following doses: 15 mg/kilogram (kg) if body weight <13 kg, or 200 mg if body weight ≥13 kg. If ≥7 years of age, participants will receive a capsule formulation (200 mg) orally TID at one of the following doses: 200 mg if body weight ˂25 kg, or 400 mg if body weight ≥25 kg.
Drug: Vatiquinone
Vatiquinone will be administered per dose and schedule specified in the arm.




Primary Outcome Measures :
  1. Number of Participants With Adverse Events (AEs) [ Time Frame: Baseline up to approximately 5 years ]

Secondary Outcome Measures :
  1. Change From Baseline in the Modified Friedreich Ataxia Rating Scale (mFARS) at Year 5 [ Time Frame: Baseline, Year 5 ]
