This retrospective cohort study looks at people with genetically confirmed Friedreich Ataxia who received omaveloxolone under early access and completed six months of treatment. Swallowing difficulty (dysphagia) is measured by the Sydney Swallow Questionnaire (SSQ) at treatment start and after six months. The study also compares SSQ results with ataxia severity (SARA), ambulatory status, and GAA repeat size.
What it is studying. The study examines changes in dysphagia severity (measured by the Sydney Swallow Questionnaire) from treatment start to six months in people with Friedreich Ataxia who received omaveloxolone during early access.
What the researchers hope to learn. Measure change in dysphagia after six months of omaveloxolone treatment; compare swallowing scores (SSQ) with ataxia severity (SARA); assess correlations with ambulatory status and GAA expansion size.
What this study is about
The study's own summary, as published on ClinicalTrials.gov. Underlined terms have a short explanation.
Friedreich's ataxia (FA) is a rare, inherited neurodegenerative disease that typically begins in children and young people. It primarily affects the spinal cord, peripheral nerves and cerebellum of the brain. Clinical manifestations include progressive gait and limb ataxia, auditory and optic neuropathy, cardiomyopathy, scoliosis, dysarthria, and dysphagia. In advanced stages, individuals may become wheelchair-dependent, leading to a severe loss of autonomy and reduced life expectancy. To date, there are no effective treatments known to reverse or halt disease progression. Heart disease remains the leading cause of death in individuals with FA. In January 2024, Omaveloxolone was approved for early access in France to treat FA in patients aged 16 years and older. Dysphagia is a central manifestation in FA, and may lead to severe complications such as malnutrition, dehydration, and aspiration-related pneumonia, as well as reduced self-esteem and social isolation. Despite its clinical relevance, dysphagia remains underexplored in clinical trials, including in major Omaveloxolone studies where no specific tool for measuring dysphagia has been incorporated. This study aimed to comprehensively evaluate the effect of Omaveloxolone on dysphagia after six months of treatment, in a cohort of French patients with Friedreich's ataxia who benefited from early access to treatment between February 2024 and May 2025. The severity of dysphagia will be assessed using the Sydney Swallow Questionnaire (SSQ), completed by patients at baseline and after six months of Omaveloxolone treatment.

This is a retrospective review of existing clinical data: researchers will use SSQ scores taken at treatment start (baseline) and after six months of omaveloxolone and other information already in medical records. The study also uses existing SARA (ataxia) scores and GAA expansion size from patient files when available. No new testing procedures, samples, or drug administration are described in the registry record for this study.
How the study is structured. A retrospective observational cohort review: researchers use medical records and patient-completed SSQs from the start of omaveloxolone treatment and again after six months. All participants already received the drug as part of early access; the study does not assign treatments or randomize participants. Analyses compare SSQ scores over time and against other clinical measures (SARA score, ambulatory status, GAA repeat size).
Questions you could ask
These questions are suggestions for a conversation with the study team or your own clinician, not advice.
- This is an observational study, so the study itself gives no treatment. What would taking part involve for me, and would it change my usual care?
- The listed sites are in France. Is any of them reachable for me, and does the study help with travel?
- Which of the eligibility criteria would need to be checked with tests before I could join?

Terms used on this page · explanations by MedicalUpdates.ai
- life expectancy
- Some studies require that, in the investigator's judgement, a participant is likely to live long enough to complete the study period. It is a study requirement, not a prediction about any individual.
- cohort
- A group of people who share a characteristic, such as a diagnosis, and are studied together. 'Prospective' means they are followed forward from enrolment; 'retrospective' means existing records are reviewed.
- baseline
- Measurements taken at the start of the study, before any study treatment, so that later results can be compared with them.
- Inclusion Criteria
- The conditions a person must meet to be considered for the study, for example a confirmed diagnosis, an age range or a test result.
- Exclusion Criteria
- The conditions that rule a person out even if they meet the inclusion criteria, for example other illnesses, certain medicines or pregnancy.
