Participate in a Clinical Trial
Without the participation of people with MS, it would be impossible to develop new and better therapies and other interventions.
Epstein Barr Virus Infection in Patients With Radiologically Isolated Syndrome
Study Purpose
The clinical course of RRMS patients is variable. Among RIS-Consortium international cohorts, one third of RIS patients progressed to MS at 5 years and 52.2% at 10 years. Biomarkers predictive of MS conversion are key elements to organize personalized medical care, for both follow-up and treatment strategies. EBV seems to be an interesting candidate regarding its involvement MS pathophysiology. It can be easily assess in blood sample in contrast to others prognostic biomarkers validated in RIS : oligoclonal bands and NfL levels in cerebrospinal fluid and serum. In RIS, treatment targeting EBV could significantly modify the course of the disease. The investigators aim to make the fisrt description of the EBV epidemiology (immunoglobulin (Ig)M and IgG anti-viral capsid antigen (VCA), IgG anti Epstein-Barr nuclear antigen (EBNA)) among RIS patients and to investigate a correlation between the different antibodies' titers (IgM VCA, IgG VCA, IgG EBNA) and the course of the disease (clinical conversion or evidence of disease activity (EDA)).

Study Type
An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes. An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes. Searching Both is inclusive of interventional and observational studies. |

Trial ID:
This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries. |
NCT05815108 |
|
Phase
Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans. Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data. Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs. Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use. |
