Ublituximab (Briumvi) for early relapsing MS

Ublituximab (Briumvi) for Early Forms of Relapsing Multiple Sclerosis

Phase 4 Interventional Northwestern University · NCT07225361

This study will test whether giving Ublituximab (Briumvi) about twice a year is safe and changes a blood marker (neurofilament light) in adults with early relapsing MS.

What this trial studies

This open-label, single-arm Phase 4 study will enroll up to 40 adults with early relapsing MS who plan to start Ublituximab and follow them for approximately 96 weeks. Participants will receive Ublituximab on an every-24-week schedule (with flexibility to every 24–26 weeks for insurance reasons) and complete baseline and follow-up visits at 24, 48, 72, and 96 weeks. Safety and tolerability data will be collected through scheduled questionnaires and coordinator contacts, while plasma neurofilament light chain will be measured at baseline and every 24 weeks to track biomarker changes. All study visits are conducted at Northwestern Memorial Hospital and study activities are distinct from routine clinical care.

Who should consider this trial

Good fit: Ideal candidates are adults 18–70 with relapsing MS diagnosed within the past five years, EDSS under 2.5, fewer than 10 brain lesions on MRI, and planning to start Ublituximab without prior B‑cell–depleting therapy.

Not a fit: Patients who have received prior B‑cell–depleting agents, have more advanced or non-relapsing MS, or cannot attend in-person visits are unlikely to benefit from enrolling.

Why it matters

Potential benefit: If successful, the study could show that twice-yearly Ublituximab is well tolerated in early relapsing MS and that it lowers blood neurofilament light, supporting earlier targeted treatment.

How similar studies have performed: Randomized trials of Ublituximab and other anti‑CD20 therapies have shown clinical benefit in relapsing MS and prior work has demonstrated reductions in neurofilament light with B‑cell depletion, so this protocol builds on existing evidence.
