Characterizing new patient types with spinal muscular atrophy treated with SMN therapies

Official title: Characterization of New Phenotypes of Patients With Spinal Muscular Atrophy Treated With SMN Restoring Therapy

Run by Hospices Civils de Lyon · NCT06321965 · Data updated 2026-11-12

This study is trying to understand how different types of spinal muscular atrophy in children under 16 respond to new treatments that boost SMN protein levels, while also looking at their muscle strength, thinking skills, and heart health over two years.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are children aged 0 to 15 years with genetically confirmed SMA who are receiving SMN restoring therapies.

Probably not a fit

Patients with other significant neurological diseases or conditions that interfere with SMA assessment may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study aims to characterize new phenotypes of patients with spinal muscular atrophy (SMA) who are being treated with therapies that restore SMN protein expression, such as nusinersen, risdiplam, and onasemnogene abeparvovec. It will involve prospectively following children under 16 years old with genetically confirmed SMA for two years, evaluating their muscle function, cognitive abilities, and cardiac health. Additionally, the study will assess the relevance of various assessment tools for monitoring this population and collect data on the economic impact of SMA treatment in France.

Why it matters

Potential benefit: If successful, this study could enhance understanding of SMA and improve treatment strategies for affected children.

How similar studies have gone: Other studies have shown success in characterizing SMA phenotypes and evaluating treatment impacts, making this approach both relevant and timely.
