Ocrelizumab and GLP‑1 agonists in people with multiple sclerosis

People With Multiple Sclerosis Treated With Ocrelizumab and GLP-1 Agonists

Observational Northwestern University · NCT07207148

What this trial studies

This observational cohort will follow adults with MS who are already taking ocrelizumab and a GLP‑1 agonist for approximately 72 weeks, with data collection every four weeks using remote surveys and periodic Zoom checks. Aim 1 uses patient‑reported outcomes including the PDDS and ambulation score as primary endpoints, while Aim 2 compares clinical disability measures (EDSS, 25‑foot walk, 9‑hole peg test, SDMT) before GLP‑1 start and at week 72 to identify progression independent of relapse activity (PIRA). Participants report medication use, weight, exercise, tolerability, and other PROMS; coordinators follow up by phone if surveys are missed. The study enrolls participants with available MRI confirmation of MS and excludes those with recent relapse, recent systemic steroids, prior lymphoablative treatments, or very low BMI.

Who should consider this trial

Good fit: Adults age 18–70 with a neurologist‑confirmed diagnosis of MS, BMI ≥24 kg/m2, EDSS <7.0, MRI confirming MS, and who have received ocrelizumab within the past 6 months and are taking a GLP‑1 medication are ideal candidates.

Not a fit: People not on ocrelizumab, those with EDSS ≥7.0, underweight or malnourished individuals, recent relapse or recent systemic steroid/surgery within exclusion windows, or those with prior lymphoablative therapies are unlikely to qualify or benefit from this protocol.

Why it matters

Potential benefit: If successful, results could show that GLP‑1 drugs used with ocrelizumab help slow disability progression and preserve walking and hand function in people with MS.

How similar studies have performed: GLP‑1 agonists have shown metabolic and neuroprotective signals in animal studies and some small human reports, but combining GLP‑1 therapy with ocrelizumab to affect PIRA in MS is largely novel and human evidence is limited.
