Abstract

Myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD) can follow a relapsing course, yet evidence for effective maintenance therapy remains limited. Interleukin-6 receptor (IL-6R) inhibition has emerged as a potential relapse-prevention strategy.
To evaluate the efficacy and safety of tocilizumab and satralizumab in patients with MOGAD.
Systematic review and random-effects proportional meta-analysis conducted in accordance with PRISMA 2020.
PubMed/MEDLINE, Scopus, Web of Science, and Google Scholar were searched from inception through 14 July 2026. Eligible studies reported outcomes in patients with MOGAD treated with an IL-6R inhibitor. The primary outcome was the proportion remaining relapse-free during treatment. Secondary outcomes included annualized relapse rate (ARR), disability, MRI activity, and infectious adverse events. Proportions were pooled using DerSimonian-Laird random-effects models, and study quality was assessed using the Newcastle-Ottawa Scale.
Six observational studies comprising 182 treated patients were included. The pooled relapse-free proportion was 85.0% (95% CI, 78.7%-89.6%; I ² =0%). ARR decreased consistently across studies, while disability generally stabilized or improved and MRI inflammatory activity decreased or remained stable where reported. Three studies involving 142 patients contributed safety data, with a pooled infectious adverse-event proportion of 28.0% (95% CI, 21.1%-36.0%; I ² =0%). Four studies were rated high quality and two moderate quality.
IL-6R inhibition was associated with substantial relapse control in selected patients with MOGAD, supporting its potential role as a maintenance therapy. However, the evidence remains limited by observational designs, heterogeneous treatment regimens and follow-up, concomitant therapies, and the influence of one large cohort.
