Summary

Neuromyelitis optica spectrum disorder (NMOSD) is a central nervous system autoimmune condition mainly involving the spinal cord, optic nerves, and area postrema. The anti-aquaporin-4 (AQP4)-Immunoglobulin G (IgG) is a specific biomarker for NMOSD. Glucocorticoids(GCs) are used as first-line treatment for NMOSD. Oral glucocorticoids tapering is always suggested following the pused therapy in the maintenance phase. Inebilizumab, a humanized monoclonal antibody targeting CD19, has been proven effective in preventing NMOSD relapses. This study aims to evaluate and compare the efficacy and differences between glucocorticoids slow-tapering and rapid-tapering strategies combined with inebilizumab in preventing relapses in AQP4-IgG-seropositive NMOSD patients following an acute attack, with the goal of determining the optimal approach to steroid tapering and discontinuation after initiation of inebilizumab.

Conditions

  • Neuromyelitis Optica (NMO)
  • Neuromyelitis Optica Spectrum Disorders (NMOSD)

Interventions

DRUG

Slow-tapering glucocorticoids + Inebilizumab

Slow-tapering glucocorticoids+Inebilizumab arm: A 300 mg intravenous infusion of inebilizumab will be administered on Day 1 and Day 15, followed by 300 mg infusions every 26 weeks thereafter. Prednisone will be initiated at a daily dose of 60 mg as concomitant therapy with inebilizumab. The prednisone dose will be tapered as follows: a reduction of 5 mg every 2 weeks until reaching 20 mg/day(Week 16); thereafter, a reduction of 5 mg every 4 weeks until discontinuation (a total duration of 32 weeks for combined inebilizumab and glucocorticoids therapy).

DRUG

Rapid-tapering glucocorticoids + Inebilizumab

Rapid-tapering glucocorticoids+Inebilizumab arm: A 300 mg intravenous infusion of inebilizumab will be administered on Day 1 and Day 15, followed by 300 mg infusions every 26 weeks thereafter. Prednisone will be initiated at a daily dose of 60 mg as concomitant therapy with inebilizumab, with a tapering schedule of 5 mg reduction per week until discontinuation (a total duration of 12 weeks for combined inebilizumab and glucocorticoids therapy).
