Observing the progression of Spinocerebellar Ataxia Type 27B

Spinocerebellar Ataxia Type 27B Natural History Study (SCA27B-NHS)

Observational University Hospital Tuebingen · NCT06472557

This study is trying to understand how Spinocerebellar Ataxia Type 27B progresses by looking at different tests and samples from people with the condition and those at risk for it.

What this trial studies

This international, multi-center observational study aims to capture and validate the progression of Spinocerebellar Ataxia Type 27B (SCA27B) through a combination of clinical assessments, digital motor evaluations, and molecular biomarkers. Participants, including those at risk for the disease, will be assessed annually, with data collected in a specialized clinical database. The study will also involve the collection of biosamples for further analysis, aiming to identify the most effective outcome measures for future therapeutic trials in SCA27B.

Who should consider this trial

Good fit: Ideal candidates include individuals with a genetic diagnosis of SCA27B, asymptomatic first-degree relatives at risk, and healthy controls without neurological or psychiatric conditions.

Not a fit: Patients who do not have a genetic diagnosis of SCA27B or those with concurrent neurological or orthopedic diseases may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved understanding and measurement of disease progression in SCA27B, paving the way for more effective treatments.

How similar studies have performed: While this approach is comprehensive, similar observational studies have shown promise in understanding other forms of ataxia, suggesting potential for success in this novel context.
