Assessing swallowing difficulties in spinal muscular atrophy patients

Implementation of Flexible Endoscopic Evaluation of Swallowing (FEES) and Standardized FEES Scores in the Diagnostic Work-up of Dysphagia in Spinal Muscular Atrophy - DYS-SMA Trial

Not applicable Interventional University of Giessen · NCT04773470

This study is testing how swallowing difficulties affect people with spinal muscular atrophy and whether new treatments like Risdiplam can help improve their swallowing over time.

What this trial studies

This project aims to evaluate the frequency and severity of dysphagia and bulbar dysfunction in patients with spinal muscular atrophy (SMA) types 1, 2, and 3 using Flexible Endoscopic Evaluation of Swallowing (FEES) and validated dysphagia scores. The study will track changes in swallowing function over time in newly diagnosed patients and those starting treatment with new SMA therapies, particularly Risdiplam. Data will be compared between groups receiving different treatments to understand the impact on swallowing difficulties.

Who should consider this trial

Good fit: Ideal candidates include patients with genetically confirmed 5q-linked spinal muscular atrophy who are being followed at the neuromuscular center in Giessen.

Not a fit: Patients with physical illnesses that could interfere with assessments or those in poor general condition may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved management and treatment strategies for dysphagia in SMA patients.

How similar studies have performed: While there have been studies on dysphagia in SMA, this specific approach using FEES in conjunction with new SMA therapies is relatively novel.
