Official title
Evaluation of MRI Biomarkers Predictive of Disability Progression in Patients With Multiple Sclerosis
Overview
The transition from relapsing-remitting multiple sclerosis to secondarily progressive multiple sclerosis (SPMS) is difficult to identify. Typically, SPMS is diagnosed retrospectively, with a significant delay, on the basis of a clinical history of progressive worsening, independent of relapses. Thus, SPMS is often associated with a considerable period of diagnostic uncertainty. The use of ultra-high field imaging can shed light on the mechanisms of disability progression thanks to its better spatial resolution and advanced imaging techniques. The new morphological imaging techniques make it possible to visualize chronic inflammatory lesions and to evaluate their evolution. It also allows for the precise measurement of brain atrophy, a reference in the evaluation of neurodegeneration. Metabolic imaging via proton spectroscopy allows the analysis of several promising cerebral metabolites that can provide information on cellular energy metabolism, mitochondrial function, or oxidative stress, and can help identify tissues at risk of neurodegeneration. Sodium imaging can provide information on axonal energy metabolism before the occurrence of stable and irreversible axonal damage. This technique is promising as an early marker of neurodegeneration.
Interventions
- Other magnetic resonance spectroscopy
Investigation of the association, in patients with multiple sclerosis, between MRI biomarker data at inclusion and progression of physical disability during follow-up (6, 12, 18 and 24 months) assessed by a composite endpoint EDSS plus (EDSS, 9HPT, T25FW)
Primary outcome measures
- Identify imaging biomarkers at inclusion predictive of disability progression. [Time frame: up to 24 months]
Secondary outcome measures (3)
- Determine the correlation between brain MRI and the concentration of imaging biomarkers (mmols) at 6, 12, 18 and 24 months. [Time frame: up to 24 months]
- Develop realistic mathematical models of disease progression associated with clinical assessment of disability through dynamics, by the EDSS-plus score (EDSS scale from 0 to 10, T25FW in seconds, 9HPT in seconds). [Time frame: up to 24 months]
- Develop an artificial intelligence algorithm to identify predictive markers for disability. The artificial intelligence algorithm utilizes patients' clinical (EDSSS-Plus Scale) and radiological (brain MRI) characteristics. [Time frame: up to 24 months]
Eligibility criteria
