United States, Belgium, China160 participantsStarted 2026-01-14
Plain-language summary
This is a randomized, open-label, parallel, Phase 3 study with 2-arms for treatment.
The purpose of this study is to evaluate SC administration of frexalimab every 4 weeks (q4w) compared to IV administration of frexalimab q4w in male and female participants with RMS and nrSPMS (aged 18 to 60 years at the time of enrollment). People diagnosed with MS are eligible for enrollment as long as they meet all the inclusion criteria and none of the exclusion criteria.
Study details include:
The study intervention duration will be 48 weeks (12 months) for Parts A and B combined. Optional Part C will last until the initiation of a long term safety study for Frexalimab.The follow up duration after the end of study intervention (in case of discontinuation) will be 6 months.
The number of scheduled visits (Parts A and B) will be 17 or 11 for participants receiving frexalimab SC or IV, respectively, with an on-site visit frequency of every month between Week 4 and Week 24 in Part A, then every 1 to 3 months in Part B, then every 6 months in Part C. Participants discontinuing treatment before the End of Study will have an additional 3 follow-up visits.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
