Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

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 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.
