Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Ravulizumab
During the Primary Treatment Period, all participants will receive weight-based dosing of ravulizumab IV for a total of 50 weeks of treatment.
During the Extension Period, participants will continue to receive weight-based dosing of ravulizumab IV for up to 104 weeks.
Ravulizumab
Participants will receive a weight-based loading dose of ravulizumab on Day 1, followed by weight-based maintenance treatment with ravulizumab on Day 15 and every 8 weeks (q8w) after or once every 4 weeks (q4w) depending on weight.
During the Extension Period, participants will continue to receive weight-based maintenance doses of ravulizumab IV on Day 351 and q8w or q4w, depending on weight.

* Use of intravenous immunoglobulin (IVIg) or plasma exchange (PE) within 3 weeks prior to Screening.
* Participation in another investigational drug or investigational device study (other than Study ECU-NMO-303) within 5 half lives of that investigational product (if known) or 30 days before initiation of the first dose of study drug, whichever is longer.
* Use of immunomodulatory therapies for multiple sclerosis within 3 months prior to Screening.
