About this study

Official title: Protein A Immunoadsorption for the Treatment of Acute Episodes of Neuromyelitis Optica Spectrum Disorder:A Multicenter, Open-label, Superiority, Randomised Trial

To clarify the efficacy and safety of protein A immunoadsorption therapy for acute exacerbations of neuromyelitis optica spectrum disorders(NMOSD), we designed a multicenter, open-label, superiority randomized controlled clinical trial, planning to enroll 144 patients with NMOSD. We plan to treat patients with acute NMOSD using protein A immunoadsorption combined with high-dose intravenous methylprednisolone, and compare this with treatment using high-dose intravenous methylprednisolone alone. The aim is to observe the impact and safety of protein A immunoadsorption on the treatment efficacy for these patients experiencing acute exacerbations of NMOSD, ultimately providing more comprehensive clinical evidence to support treatment protocols for the acute phase of NMOSD.

Being tested

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Protein A immunoadsorptionDevice

    The experimental group was treated with a combination of protein A immunoadsorption and intravenous methylprednisolone. The methylprednisolone was administered following a regimen of 1g for 5 days, 0.5g for 3 days, 0.25g for 2 days, and 0.12g for 1 day. Protein A immunoadsorption was conducted every other day, unless a physician determined that the patient's condition was unsuitable for treatment, in which case treatment was administered according to medical advice. A total of 5 treatments were given, with each session involving the regeneration of plasma at 1 to 3 times the plasma volume.

  • intravenous methylprednisoloneDrug

    The control group was treated with intravenous methylprednisolone, following a regimen of 1g for 5 days, 0.5g for 3 days, 0.25g for 2 days, and 0.12g for 1 day.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. To assess the effectiveness of the treatment, the change in the Kurtzke Expanded Disability Status Scale (EDSS) score is evaluated one month after the start of treatment compared to the baseline. The baseline is defined as the patient's condition before

    To assess the effectiveness of the treatment, the change in the Kurtzke Expanded Disability Status Scale (EDSS) score is evaluated one month after the start of treatment compared to the baseline. The baseline is defined as the patient's condition before treatment began, or if the patient had not yet reached a plateau during the initial treatment phase and continued to worsen during hospitalization, the most severe stage during the current hospitalization is used as the baseline.The EDSS is a scale used for the objective and repeatable quantification of disability in patients, with scores ranging from 0 to 10. A score of 0 indicates normal function, while a score of 10 indicates death. An increase in the EDSS score reflects worsening symptoms.The method of evaluation involves calculating the EDSS score difference as follows:

    EDSS Score Difference = EDSS Score (Baseline) - EDSS Score (1 Month After Treatment Start).

    Measured: Evaluation timing includes from the screening period to the baseline and the EDSS score assessment one month after starting treatment.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 30 Apr 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Wei Qiu, Ph.D (+8615899968330, qiuwei120@vip.163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

To assess the effectiveness of the treatment, the change in the Kurtzke Expanded Disability Status Scale (EDSS) score is evaluated one month after the start of treatment compared to the baseline. The baseline is defined as the patient's condition before (time frame: Evaluation timing includes from the screening period to the baseline and the EDSS score assessment one month after starting treatment.). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT06763848, which also lists 6 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 30 Apr 2025.
