Momentum: Treatment Response Among Chinese Neuromyelitis Optica Spectrum Disorders
Study Details
Study Description
Brief Summary
Neuromyelitis Optica (NMO)/ Neuromyelitis Optica Spectrum Disorders (NMOSD) is an immune-mediated inflammatory demyelinating disease of the central nervous system mainly involving optic nerve and spinal cord. It is clinically characterized by simultaneous or sequential involvement of the optic nerve and spinal cord, presenting a progressive or remission and relapse course, which can lead to paralysis and blindness.
The objective of this study is to provide evidence regarding treat effects and factors related to prognosis which will help physicians better evaluable risk-benefit in NMOSD management and improve patients' outcome.

Detailed Description
Neuromyelitis Optica (NMO)/ Neuromyelitis Optica Spectrum Disorders (NMOSD) is an immune-mediated inflammatory demyelinating disease of the central nervous system mainly involving optic nerve and spinal cord. It is clinically characterized by simultaneous or sequential involvement of the optic nerve and spinal cord, presenting a progressive or remission and relapse course, which can lead to paralysis and blindness.
Globally, there is no solid data available for the diagnosis, treatment and prognosis of patients with acute Neuromyelitis Optica Spectrum Disorders (NMOSD) attack, particularly very rare data from prospective studies. This is a multicenter, prospective, real-world cohort study in patients with acute NMOSD attack in China.
Baseline data for approximately 200 patients with acute NMOSD attack from approximately 4 centers will be collected. Patients with acute NMOSD attack (including first episodes and relapses) whose expansile disability status score (EDSS ) ≥ 2 points at baseline will be eligible to be further included in prospective study cohort for analysis of treatment effects and prognosis.
The objective of this study is to provide evidence regarding treat effects and factors related to prognosis which will help physicians better evaluable risk-benefit in NMOSD management and improve patients' outcome.
Study Design
Outcome Measures
Primary Outcome Measures
- Expansile Disability Status Score [at the end of the first high-dose intravenous Methylprednisone (IVMP) therapy (up to 3 weeks )among subjects who received high-dose IVMP]
Compared with baseline, changes in EDSS(Expansile Disability Status Score )at the end of the first high-dose intravenous Methylprednisone (IVMP) therapy among subjects who received high-dose IVMP. EDSS score is based on the evaluation of eight functional systems of the central nervous system.The total score of the assessment is between 0 and 10 points, and each 0.5 is divided into one grade, which is divided into 20 grades.
Secondary Outcome Measures
- Expansile Disability Status Score [at discharge (7 days after last treatment)]
Compared with baseline, proportion of subjects with EDSS improved ≥1 point at discharge (7 days after last treatment)
- Changes In AQP4-IgG [at the end of the first IVMP therapy(up to 3 weeks) among subjects who received high-dose IVMP]
Compared with baseline , changes in AQP4-IgG at the end of the first IVMP therapy among subjects who received high-dose IVMP
- As Assessed By Snellen Chart [at the end of the first high-dose IVMP theraty (up to 3 weeks) among subjects who received high-dose IVMP]
Compared with baseline , changes in visual acuity (as assessed by Snellen chart) at the end of the first high-dose IVMP therapy among subjects who received high-dose IVMP
- PGI-I Score [at the end of the first high-dose IVMP therapy(up to 3 weeks) among subjects who received high-dose IVMP]
Score of Patient Global Improvement-Impression (PGI-I) at the end of the first high-dose IVMP therapy among subjects who received high-dose IVMP Patient Global Impressions (PGI)-Improvement Mark the box that best describes how you (the patient) have felt in general since you started taking this medicine. (Choose one) 1 = Very assessed, 2 = Much better, 3 = A little better, 4 = The same, 5 = A little worse, 6 = Much worse, 7 = Very much worse

- As Assessed By Snellen Chart [at discharge (7 days after the last treatment)]
Compared with baseline, changes in visual acuity (as assessed by Snellen chart) at discharge (7 days after the last treatment)* among subjects who received high-dose IVMP
- PGI-I Score [at discharge (7 days after the last treatment)]

- Expansile Disability Status Score [at discharge (7 days after the last treatment)]
Compared with baseline, changes in EDSS at discharge (7 days after the last treatment) * among subjects who received high-dose IVMP
- The proportion of patients who did not respond to the first high-dose IVMP therapy(up to 3 weeks) [at discharge (7 days after the last treatment)]
The proportion of patients who did not respond to the first high-dose IVMP therapy(up to 3 weeks)
