Therapy in the Acute Phase of NMOSD: A Multicenter Prospective Real-World Study

This project is a multi-center, prospective, real-world cohort study that collects clinical data of Chinese patients with AQP4-positive NMOSD in the acute stage. It comprehensively assesses the clinical outcomes of the patients and aims to compare the clinical efficacy and safety of icoxib as a combined add-on treatment versus simple hormone shock therapy during the acute phase of NMOSD.Using simple hormone shock therapy (IVMP) as the control group, the efficacy and safety of etanercept treatment in the acute attack phase of Chinese patients with AQP4-positive neuromyelitis optica spectrum disorder (NMOSD) were evaluated.

Eculizumab For the Acute Attack of Neuromyelitis Optica Spectrum Disorder

Neuromyelitis optica spectrum disorder (NMOSD) is a relapsing, inflammatory autoimmune disorder of the central nervous system characterized by the pathogenic anti-aquaporin 4 antibody (AQP4-IgG). The objectives of this study are to assess the efficacy and safety of eculizumab for treatment of patients with neuromyelitis optica spectrum disorders during acute phase who are anti-aquaporin-4 (AQP4) antibody-positive. Eculizumab, a humanized monoclonal antibody, inhibits the terminal complement protein C5 and prevents its cleavage into C5a and the formation of C5b-9 (MAC), has approved for preventive treatment of NMOSD. Given the high efficacy of C5 inhibition, eculizumab is proposed to potentially provide rapid relief from astrocyte destruction by reducing MAC formation, which could contribute to the fast alleviation of neurological deficit during NMO acute attack. The potential of eculizumab warrants further investigation as a treatment for acute neuromyelitis optica spectrum disorders attacks.
