  6. EDSS score ≤ 7.
  7. Participants who enter the study receiving supportive immunosuppressive therapies (ISTs) for the prevention of relapse, either in combination or monotherapy, must be on a stable dosing regimen of adequate duration.
  8. Female participants of childbearing potential must have a negative pregnancy test (serum human chorionic gonadotropin) at Screening and follow protocol-specified contraception guidance for avoiding pregnancy while on treatment and for 5 months after the last dose of eculizumab.
