Digital biomarkers in people with radiologically isolated syndrome and MS who have normal neurological exams
Official title: Comparison of Digital Biomarkers in Subjects With Radiologically Isolated Syndrome (RIS) and Multiple Sclerosis (MS) Patients With Clinically Normal Neurological Examination
Run by Centre Hospitalier Universitaire de Nice · NCT07135752 · Data updated 2026-11-12
This study will test whether digital biomarkers can tell apart people with radiologically isolated syndrome from multiple sclerosis patients who have a normal neurological exam.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults in France with RIS by the 2023 criteria or people with MS who have a normal neurological exam by McDonald 2017, who are covered by social security and do not have progressive disease or unrelated neurological deficits.
✕Probably not a fit
People with progressive MS or with motor, visual, or cognitive impairments unrelated to MS that interfere with testing are unlikely to gain benefit from this study's comparisons.

What this trial studies
Participants include people with radiologically isolated syndrome (RIS) who meet the 2023 criteria and people with multiple sclerosis who have a clinically normal neurological exam under McDonald 2017 criteria. At CHU de Nice, both groups will undergo precision assessments of digital biomarkers, with the resulting digital measures compared between groups. Clinical and imaging information, including routine MRI findings, will be used alongside digital data to look for patterns that differ between RIS and clinically silent MS and might predict future conversion. The protocol excludes people with unrelated motor, visual, or cognitive deficits and anyone with progressive MS, and participants must be affiliated to social security.
Why it matters
Potential benefit: If successful, this approach could offer noninvasive, more frequent monitoring to help identify people at higher risk of converting from RIS to symptomatic MS earlier.
How similar studies have gone: Epidemiological RIS cohorts have identified imaging and clinical risk factors for conversion, and early work on digital biomarkers in MS is promising but has not yet produced widely adopted clinical tools.
