Monoclonal Antibody-Based Therapies for AQP4-Positive NMOSD

China200 participantsStarted 2025-07-01

Plain-language summary

The primary objective of this registry study is to evaluate the therapeutic efficacy and safety profiles of distinct monoclonal antibody-based therapies for aquaporin-4 immunoglobulin G-seropositive neuromyelitis optica spectrum disorders within the Chinese population under real-world clinical conditions. Secondary objectives include quantitative assessment of longitudinal neuroimaging biomarker variations and immunological profile alterations in longitudinal biological specimens pre- and post-therapeutic intervention.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.

Exclusion criteria

. Clinically significant medical history of cardiac, endocrine, hematologic, hepatic, immune, infectious, metabolic, renal, pulmonary, neurological, dermatologic, psychiatric, or other major systemic conditions that, in the investigator's judgment, would preclude safe trial participation.
. Prior cerebrovascular events resulting in a baseline modified Rankin Scale (mRS) score \>3.
. Hypersensitivity to the investigational therapeutic agent(s) or their excipients.
. Documented history or positive screening test for human immunodeficiency virus (HIV).
. Active hepatitis C virus (HCV) infection, defined as detectable HCV RNA with concomitant anti-HCV antibody positivity. Subjects with anti-HCV antibody positivity and undetectable HCV RNA remain eligible.
. Active hepatitis B virus (HBV) infection, defined as hepatitis B surface antigen (HBsAg) positivity and/or total hepatitis B core antibody (anti-HBc) positivity. Subjects with prior natural infection (HBsAg-negative, anti-HBc-positive, and anti-HBs-positive) or vaccination-induced immunity (HBsAg-negative, anti-HBc-negative, and anti-HBs-positive) are eligible.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
