Neurofilament Assay for the Diagnosis of ALS

Conditions
Progressive Motor Neuron Disease Without Definite Diagnosis
Registration Number
NCT05077696
Lead Sponsor
Assistance Publique - Hôpitaux de Paris
Brief Summary

The aim of the study is to evaluate the interest of the determination of pNFH and NFL neurofilaments in serum for the diagnosis of ALS in patients with a diagnostic standoff after evaluation in an expert ALS center. The hypothesis is that one of these biomarkers, or their combined analysis, will make it possible to confirm or invalidate the diagnosis of ALS.

Detailed Description

For this study, which aims to evaluate a test to help in the diagnosis of ALS that could be integrated into routine practice, it was preferred to use blood tests. Blood sampling is significantly less invasive than CSF sampling, and more easily generalized, including in ambulatory conditions.
