Investigating the effects of Ocrevus on cognitive fatigue in multiple sclerosis

A Biomarker for Cognitive Fatigue Using Functional Imaging in MS

Observational Kessler Foundation · NCT04448977

This study is testing how the medication Ocrevus affects cognitive fatigue in people with relapsing-remitting multiple sclerosis to see if it helps them think better during challenging tasks.

What this trial studies

This research examines how the disease-modifying medication Ocrevus affects cognitive fatigue in individuals with relapsing-remitting multiple sclerosis (RRMS). The study utilizes functional MRI (fMRI) to assess changes in brain activity related to cognitive fatigue during demanding tasks. Participants will include those newly prescribed Ocrevus or Copaxone, as well as healthy volunteers. The research aims to understand how cognitive fatigue evolves with treatment duration and its impact on specific brain regions.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18-64 with relapsing-remitting multiple sclerosis who have been newly prescribed a disease-modifying medication.

Not a fit: Patients with significant neurological events, psychiatric illnesses, or those unable to undergo MRI may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved management strategies for cognitive fatigue in patients with multiple sclerosis.

How similar studies have performed: Other studies have explored cognitive fatigue in multiple sclerosis, but this specific investigation into Ocrevus's effects is relatively novel.
