    Describes the nature of a clinical study. Types include:

    • Observational study — observes people and measures outcomes without affecting results.
    • Interventional study (clinical trial) — studies new tests, treatments, drugs, surgical procedures or devices.

About this study

Neuromyelitis optica (NMO) is an inflammatory disease of the central nervous system that is associated with autoantibodies to aquaporin-4. Treatment options for prevention of clinical relapses of NMO include immunosuppressive medications. Plasma exchange (PLEX) is commonly used as a rescue therapy for NMO relapses but ongoing, regular PLEX procedures (maintenance PLEX) is sometimes used to prevent relapses. This observational registry will record feasibility, tolerability, safety, and preliminary efficacy data regarding maintenance PLEX for NMO.

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. If you need assistance understanding the eligibility criteria, please contact the study team.
