Study Endpoints
Primary Endpoints
Time to Adjudication Committee (AC)-Determined Neuromyelitis Optica Spectrum Disorder (NMOSD) Attack During RCP
Day 1 (Baseline) through Day 197

The NMOSD attack is defined as the presence of new or worsening symptom(s) related to NMOSD that meet at least one of the 18 protocol-defined attack criteria. These criteria were developed in conjunction with a panel of disease experts and with Food and Drug Administration input, and were intended to be clinically meaningful, objective, quantifiable, and able to be used worldwide. Only attacks positively adjudicated by the AC were used for the primary analysis.

Secondary Endpoints
Percentage of Participants With Worsening in Expanded Disability Severity Scale (EDSS) Score From Baseline to the Last Visit of RCP
Day 1 (Baseline) through Day 197
Change From Baseline in Low-Contrast Visual Acuity Binocular Score to the Last Visit of RCP
Day 1 (Baseline) through Day 197
Cumulative Number of Active Magnetic Resonance Imaging (MRI) Lesions During RCP
From Screening (Day -28) to Day 197

Placebo/InebilizumabPLACEBO_COMPARATORAquaporin-4-antibody (AQP4-IgG) sero positive and sero negative participants will receive IV dose of placebo matched to inebilizumab on Day 1 and Day 15 of the RCP. The participants who enter OLP will receive IV inebilizumab 300 mg on both Day 1 and Day 15, followed by a single IV dose of inebilizumab 300 mg every 6 months until maximum of 3 years after the last participant enters the OLP. Participants will have choice to enter in the SFP at any point during RCP or OLP and will be free to pursue other treatment options otherwise prohibited during the RCP and OLP. Participants will continue in the SFP for 12 months from last dose of study drug.
