NCT ID NCT05147220

What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing This study
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

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.
