New pill could tame MS relapses
NCT ID NCT05147220
First seen Jun 26, 2026 · Last updated Aug 19, 2026 · Updated 3 times
Summary
This Phase 3 trial tests remibrutinib, an oral tablet, against teriflunomide in 1000 adults with relapsing multiple sclerosis. The goal is to see if remibrutinib better reduces yearly relapse rates and delays disability. Participants will then have the option to continue remibrutinib in an open-label extension.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- remibrutinib (tablet)
- What this could lead to
- If successful, remibrutinib could offer a new, effective oral option to control relapses and slow disability in multiple sclerosis.
- What could go wrong
- This is a Phase 3 trial, but results are not yet published. Remibrutinib may not prove superior to teriflunomide, and side effects are still being studied.
