Brief summary
This study is aimed to observe the effectiveness and safety of inebilizumab in the acute phase of neuromyelitis optica spectrum disorders.
Detailed description
This is a a multicentric, prospective, real word study of inebilizumab in NMOSD acute attack compared with oral immunosuppressant. A total of 50 patients will be enrolled at approximately 10 centers around China.
Interventions
DRUGInebilizumab
Inebilizumab: 300mg IV on Day1 and Day 15. The first dose of inelizumab is given during IVMP.
DRUGoral immunosuppressant
Oral immunosuppressants (azathioprine or mycolate mofetil) are initiated during IVMP.

Inclusion criteria
* 1\. Age ≥ 18 years with anti-AQP4-IgG seropositive NMOSD as defined by 2015 NMOSD diagnostic criteria by IPND (International Panel for NMO Diagnosis); 2. In the acute phase of NMOSD (definition of acute phase: new neurological symptoms or aggravation of existing symptoms within 30 days before screening, lasting at least 24 hours without with fever); 3. Patients who plan to receive or are receiving intravenous methylprednisolone therapy; 4. Expanded disability status scale (EDSS) score ≤ 8 and ≥ 2.5 during the screening period; 5. Able and willing to give written informed consent; 6. Women of childbearing potential who agree to use adequate contraception during the study.
Exclusion criteria
* 1\. Lactating and pregnant females; 2. Participate in other interventional studies within 30 days before screening or within 5 half-lives of the investigational agent before enrollment; 3. Combined with severe mental disorders and other conditions and unable to cooperate with follow-up; 4. History of malignancies; 5. Received plasma exchange, immunoadsorption or intravenous immunoglobulin therapy within 1 month before screening; 6. Patients with negative hepatitis B surface antibody (HBsAg) and positive hepatitis B core antibody (HBcAb), or HBsAg-positive virus carriers, or patients with active tuberculosis or positive tuberculosis screening without appropriate treatment history; 7. Other situations that researchers think are not suitable to participate in this study.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in Expanded Disability Status Scale (EDSS) score from baseline | 6 months | Change in Expanded Disability Status Scale (EDSS) score from baseline at the last visit(EDSS : Minimum Score 1, Maximum score 10, higher scores mean a worse outcome). |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Percentage of Participants With Disability Improvement | 6 months | Disability improvement is defined as a reduction in EDSS score of: A) \>=1.0 from the baseline EDSS score when the baseline score was \<=5.5 B) \>= 0.5 when the baseline EDSS score \> 5.5(EDSS : Minimum Score 1, Maximum score 10, higher scores mean a worse outcome). |
| Change in modified Rankin score (mRS) from baseline | 1 months, 3 months, 6 months | Change in modified Rankin score (mRS) from baseline at month 1, month 3, month 6(mRS : Minimum Score 0, Maximum score 6, higher scores mean a worse outcome). |
| Time to first relapse | 6 months | — |
| Number of New, and/or Enlarging T2 Hyperintense Lesions Detected by Magnetic Resonance Imaging (MRI) | 6 months | Number of New, and/or Enlarging T2 Hyperintense Lesions Detected by Magnetic Resonance Imaging (MRI) at the last visit |
| Change in Timed 25 Foot Walk Test from baseline | 1 months, 3 months , 6 months | Change in time taken to complete the timed 25 foot walk test from baseline |
| Change in Expanded Disability Status Scale (EDSS) score from baseline | 1 months, 3 months | Change in Expanded Disability Status Scale (EDSS) score from baseline at month 1, month 3(EDSS : Minimum Score 1, Maximum score 10, higher scores mean a worse outcome). |
| Change in serum GFAP levels from baseline | 6 months | Change in serum GFAP levels from baseline at the last visit |
