Protein A immuNoaDsorption for the Treatment of Acute Episodes of Neuromyelitis Optica Spectrum Disorder

Summary

To clarify the efficacy and safety of protein A immunoadsorption therapy for acute exacerbations of neuromyelitis optica spectrum disorders(NMOSD), we designed a multicenter, open-label, superiority randomized controlled clinical trial, planning to enroll 144 patients with NMOSD. We plan to treat patients with acute NMOSD using protein A immunoadsorption combined with high-dose intravenous methylprednisolone, and compare this with treatment using high-dose intravenous methylprednisolone alone. The aim is to observe the impact and safety of protein A immunoadsorption on the treatment efficacy for these patients experiencing acute exacerbations of NMOSD, ultimately providing more comprehensive clinical evidence to support treatment protocols for the acute phase of NMOSD.
