Study Arms:
- Placebo/Inebilizumab (Type: PLACEBO_COMPARATOR): Aquaporin-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.
- Inebilizumab/Inebilizumab (Type: EXPERIMENTAL): AQP4-IgG sero positive and sero negative participants will IV dose of inebilizumab 300 mg on Day 1 and Day 15 of RCP. The participants who enter OLP will receive IV inebilizumab 300 mg on Day 1 and matching placebo on 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.
