Summary

This phase 3 trial tests whether rituximab, a cheaper drug, works as well as ocrelizumab for active multiple sclerosis. About 600 adults with relapsing or progressive MS will receive one of the two drugs. The main goal is to see if rituximab can prevent new brain lesions as effectively as ocrelizumab.

What this could mean

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

Active substance

rituximab and ocrelizumab (drugs that target immune cells to reduce MS activity)

What this could lead to

If rituximab works as well as ocrelizumab, it could offer a more affordable treatment option for multiple sclerosis.

What could go wrong

This is a non-inferiority trial, so rituximab may turn out to be less effective or have different side effects. Results may not apply to all MS types.
