Modified Zipper Therapy for AQP4-IgG Positive Neuromyelitis Optica Spectrum Disorder

Study Title: A National, Multicenter, Randomized Controlled Trial of the Modified Zipper Therapy in AQP4 Antibody-Positive Neuromyelitis Optica Spectrum Disorder (ELITE Study) Brief Summary: The goal of this clinical trial is to evaluate the efficacy and safety of a novel sequential immunomodulation strategy, termed "Modified Zipper Therapy," in patients with acute attacks of Aquaporin-4 antibody-positive Neuromyelitis Optica Spectrum Disorder (AQP4-IgG+ NMOSD). The therapy aims to enhance neurological recovery by combining plasma exchange (PE) with immediate complement inhibition using eculizumab, following high-dose corticosteroid pulse therapy. The main questions this trial aims to answer are: Efficacy: Does the Modified Zipper Therapy (high-dose corticosteroids + plasma exchange + eculizumab) lead to a higher rate of neurological improvement at Week 12 compared to standard therapy (high-dose corticosteroids + plasma exchange alone)? For patients with NMOSD-related optic neuritis (NMOSD-ON), improvement is defined as a gain of ≥10 letters on the ETDRS chart or a decrease of ≥0.2 LogMAR in best-corrected visual acuity (BCVA). For patients with NMOSD-related longitudinally extensive transverse myelitis (NMOSD-LETM), improvement is defined as a reduction of ≥2 points on the Expanded Disability Status Scale (EDSS). Safety: What is the nature and frequency of adverse events experienced by participants receiving the Modified Zipper Therapy compared to those receiving stan…
