Summary

This study is a long-term follow-up for people with relapsing multiple sclerosis who previously completed a ublituximab trial. It aims to see if the drug remains safe and effective over time. About 1100 participants will receive ublituximab infusions, and researchers will track relapse rates and side effects.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: ublituximab (a monoclonal antibody targeting CD20)
What this could lead to: If successful, this study could confirm ublituximab as a safe and effective long-term treatment to reduce relapses in people with relapsing multiple sclerosis.
What could go wrong: This is an extension study, so participants already know they tolerate ublituximab. However, long-term risks or reduced effectiveness over time are still possible. The study is not designed to prove a cure.
