First seen Apr 05, 2026 · Last updated May 14, 2026 · Updated 5 times

Summary

This study looks at whether the MS drug ocrelizumab effectively removes B cells from lymph nodes, not just from the blood. Researchers will analyze lymph node samples from 5 people with relapsing-remitting MS who are starting ocrelizumab. The goal is to understand why some immune cells may survive treatment and how that affects long-term disease control.
