Predicting disease activity and rebound risk in MS patients treated with S1PR modulators

Predicting Disease Activity and Rebound Risk in MS Patients Treated With Sphingosine-1-phosphate Receptor Modulators (S1PRM)

Observational Insel Gruppe AG, University Hospital Bern · NCT05828901

This study looks at how stopping treatment with certain MS medications affects disease activity in people with relapsing-remitting multiple sclerosis to help manage their condition better.

What this trial studies

This observational study focuses on patients with relapsing-remitting multiple sclerosis (RRMS) who are either currently treated with or have recently stopped treatment with sphingosine-1-phosphate receptor modulators (S1PRMs) like ozanimod. The study aims to analyze immune cell responses to understand the risk of rebound disease activity after discontinuation of treatment. By evaluating the effects of S1PRMs on disease progression and relapse rates, the research seeks to provide insights into the management of MS. Participants will provide written informed consent and will be monitored for changes in disease activity.

Who should consider this trial

Good fit: Ideal candidates include adult patients with relapsing-remitting multiple sclerosis who are either on ozanimod treatment or have recently discontinued it.

Not a fit: Patients who are not diagnosed with relapsing-remitting multiple sclerosis or those with hypersensitivity to ozanimod will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could help identify patients at risk for severe relapses after stopping S1PRMs, leading to better management strategies for MS.

How similar studies have performed: While there have been retrospective analyses on the risks associated with fingolimod, the specific risks of rebound disease activity with newer S1PRMs like ozanimod are not well established, making this study a novel approach.
