Comparison of the Efficacy and Safety of Immunoadsorption and Plasma Exchange for Acute Attack of Refractory Neuromyelitis Optica Spectrum Disorders
144 participantsStarted 2019-09-01
Plain-language summary
Neuromyelitis optica spectrum disorder (NMOSD) is one common demyelinating disease of the central nervous system in young adults, with high rate of disability and recurrence, and poor natural course, which can cause a serious burden on families and society. To today, there is still a lack of prospective, multi-center, large sample clinical trial evidence for the treatment and prognosis of acute attack of NMOSD patients. This study will conduct a prospective, multi-center, single-blind, randomized controlled clinical trial of acute attacked NMOSD patients in China. The researchers plan to collect 144 NMOSD patients with acute attack in three research centers of Guangzhou (the Third Affiliated Hospital of Sun Yat-sen University, the Zhongshan Ophthalmic Center of Sun Yat-sen University, and the Guangdong 999 Brain hospital), to study the safety and efficacy of immunoadsorption therapy.
The subjects will be randomized into immunoadsorption group and plasma exchange group, and the following indicators will be evaluated: (1) changes in EDSS scores and visual acuity before and after treatment; (2) changes in AQP4-IgG levels; (3) the safety of immunoadsorption treatment.
This study is aimed to determine the efficacy and safety of immunoadsorption therapy for acute attack of refractory NMOSD patients, and to provide more sufficient clinical evidence for the therapy selection for acute phase of NMOSD patients.

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.
