Brief Summary

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

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.

Patients with Friedreich ataxia treated with Omaveloxolone

SKYCLARYS (omaveloxolone)

Intervention Type DRUG

Skyclarys is indicated for the treatment of Friedreich's ataxia in adults and adolescents aged 16 and over. Opaque capsule with "RTA 408" printed in white ink on the light green body and "50" printed in white ink on the blue cap. Capsules (size 0) measure 21.7 ± 0.3 mm in length and the outer diameter of the cap is 7.64 ± 0.06 mm. Omaveloxolone should be initiated and monitored by physicians experienced in treating patients with patients with Friedreich's ataxia. The recommended dose is 150 mg omaveloxolone (3 x 50 mg capsules) once daily.
