Summary

This study tests whether eculizumab can quickly reduce disability during acute attacks of neuromyelitis optica spectrum disorder (NMOSD), a rare autoimmune disease that damages the brain and spinal cord. About 110 adults who test positive for the AQP4 antibody and are having an attack will receive the drug. The goal is to see if it improves symptoms within 28 days by blocking a part of the immune system that causes nerve damage.
