Summary

This trial will test the safety and effectiveness of a drug to reduce inflammation in the brains of people with relapsing multiple sclerosis.

Who is the study for?
This trial is for people with relapsing forms of Multiple Sclerosis (RMS) diagnosed per the 2017 McDonald criteria, who've had symptoms for less than 20 years. Participants should have experienced at least one MS flare-up in the past two years but not within the last month before starting the trial. They must also have an EDSS score between 0 and 5.0, indicating a certain level of disability.
What is being tested?
The study tests BIIB091 alone or combined with Diroximel Fumarate (DRF) against DRF alone to see how well they control brain inflammation in RMS, as shown by MRI scans. Part one focuses on BIIB091's safety and tolerability; part two compares its effectiveness when added to DRF versus DRF treatment alone.
What are the potential side effects?
Potential side effects may include allergic reactions to either BIIB091 or DRF, infusion-related responses such as fever or chills, possible liver issues indicated by hepatitis B exclusion, and general risks associated with immune-modulating therapies like increased infection risk.
