Vatiquinone for Friedreich Ataxia
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests the long-term safety of vatiquinone for individuals with Friedreich ataxia, a rare genetic disorder affecting balance and coordination. Participants who were part of a previous study with vatiquinone will continue using the treatment. It specifically targets those who have Friedreich ataxia and completed an earlier vatiquinone study. As a Phase 3 trial, this study represents the final step before FDA approval, giving participants the opportunity to contribute to the potential availability of a new treatment.
Do I need to stop my current medications to join the trial?
The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.
Is there any evidence suggesting that vatiquinone is likely to be safe for humans?
Research shows that vatiquinone is generally safe and well-tolerated for people of all ages. Previous studies found no significant difference in unwanted effects between those taking vatiquinone and those taking a placebo (a pill with no active medicine). This suggests that any side effects are likely similar to not taking any treatment. The evidence indicates that vatiquinone could be a safe option for both children and adults with Friedreich ataxia. While more research is needed to confirm its effectiveness, its safety appears promising based on current studies.12345
Why do researchers think this study treatment might be promising for Friedreich ataxia?
Vatiquinone is unique because it offers a new approach to treating Friedreich Ataxia by targeting oxidative stress, which is a key factor in the progression of the disease. Unlike traditional treatments that mainly focus on managing symptoms, vatiquinone works at the cellular level to protect nerve cells from damage. Researchers are excited about this treatment because it has the potential to slow down the progression of the disease, which could significantly improve the quality of life for patients.
What evidence suggests that vatiquinone might be an effective treatment for Friedreich ataxia?
Research suggests that vatiquinone, the treatment under study in this trial, might help treat Friedreich ataxia (FA). In one study, participants showed noticeable improvement in their FA symptoms, as measured by a specific assessment tool. Another study found that vatiquinone slowed the progression of FA, with participants showing a 3.7-point improvement in a neurological function score compared to those not receiving the treatment. However, not all results have been positive; one study did not meet its main goal of improving another FA-related score. Overall, some evidence indicates that vatiquinone could help improve neurological function and slow the disease's progression in FA.23467
Are You a Good Fit for This Trial?
This trial is for people with Friedreich ataxia who were previously in a vatiquinone study. Participants must be willing to use effective contraception from consent until 30 days after the last dose or if they leave the study early.Inclusion Criteria

Experimental Treatment
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.
