Rövid összefoglaló (regiszter, angolul)
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 standard therapy? Researchers will compare the Modified Zipper Therapy group to the Standard Therapy group to see if the novel combination is more effective in improving visual and functional outcomes in acute AQP4-IgG+ NMOSD. Participants will: Be randomly assigned (like a coin toss) to receive either the Modified Zipper Therapy or the Standard Therapy. Undergo a treatment period involving intravenous corticosteroids and a series of plasma exchange sessions. The Modified Zipper Therapy group will also receive intravenous eculizumab infusions timed around the plasma exchange procedures. Be followed for 24 weeks after treatment completion. Attend scheduled clinic visits for comprehensive assessments including: Visual acuity testing (using ETDRS, Snellen, and low-contrast charts). Neurological function evaluations (EDSS and OSIS scores). Optical coherence tomography (OCT) and visual evoked potential (VEP) tests. Magnetic resonance imaging (MRI) scans of the optic nerves. Safety monitoring (physical exams, lab tests, ECGs).
