Therapy in the Acute Phase of NMOSD: A Multicenter Prospective Real-World Study
China200 participantsStarted 2026-02-01
Plain-language summary
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.

Inclusion criteria
. Age: 18 - 65 years old, gender not restricted.
. Patients who meet the diagnostic criteria for NMOSD as set by the International Panel for NMO Diagnosis (IPND) in 2015, and have positive serum AQP4-IgG (by CBA method or live cell method).
. Acute phase of NMOSD-ON, defined as new or worsening optic nerve dysfunction (visual acuity decline accompanied or not by eye pain and visual field defect), with an onset duration of ≤ 21 days, and clear evidence of new or recurrent optic nerve damage on imaging (new or expanded T2WI lesions, with enhancement); the best corrected visual acuity (BCVA) of the affected eye during the acute phase of NMOSD-ON (if both eyes are affected simultaneously, the worse eye is considered) drops from above 0.3 to ≤ 0.1.
. Acute phase of NMOSD-TM, defined as new or worsening spinal cord dysfunction (limb weakness or numbness, accompanied or not by urinary and defecation disorders), with an onset duration of ≤ 21 days, and clear evidence of new or recurrent spinal cord damage on imaging (new or expanded T2WI lesions, with enhancement); the EDSS score during the acute phase of NMOSD-TM increases from ≤ 4.0 to ≥ 6.0.
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.
What they're measuring
1
Expanded Disability Status Scale score,EQ-5D-5L,
Timeframe: baseline (before the acute attack and before the initiation of this treatment), and after hormone treatment at weeks 1, 2, 3, 4, 8 and 12
2
Expanded Disability Status Scale
Timeframe: Baseline (before the acute attack treatment), after 1st, 2nd, 3rd, 4th week of hormone treatment, 8th and 12th week
. Clinical onset and recurrence determination requires unanimous judgment by each center and the center committee (an independent group of 3 people).
. Agree to receive meningococcal vaccine or use eculizumab during and 2 weeks after the medication.
. Sign the informed consent.
Exclusion criteria
. Damage to the optic nerve or spinal cord caused by other non-NMOSD-related factors.
. Abnormal laboratory indicators that need to be excluded from the subjects include, but are not limited to the following indicators:
. Pregnant or lactating women, as well as those planning to become pregnant during the study period.
. Those who have received PE/IA/IVIG/FcRn/B-cell deletion/C5/IL-6 treatment within 1 month before enrollment.
. Active infections: active hepatitis B, hepatitis C, syphilis or HIV infection; active systemic infections or immunodeficiency diseases; unrelieved meningococcal infection of the meninges, or patients with severe infections that cannot use immunosuppressive drugs.
. Patients with severe internal or external diseases (not limited to such as heart failure, unstable angina pectoris, respiratory failure, pulmonary insufficiency, cachexia, organ transplantation, etc.).
. Those who have had or currently have an untreated malignant tumor that is not well controlled.
. Patients with serious physical or mental diseases that may affect the smooth implementation of the study.
