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.
