Eligibility

You can join if…

Open to people ages 2-17

  1. Male or female participants aged 2 years to < 18 years with body weight ≥ 10 kilograms (kg).
  2. Vaccinated against Neisseria meningitidis within 3 years prior to, or at the time of initiating eculizumab. Participants who initiate study drug treatment less than 2 weeks after receiving a meningococcal vaccine must receive appropriate prophylactic antibiotics until 2 weeks after the vaccination.
  3. Documented vaccination against haemophilus influenzae type b and streptococcus pneumoniae infections at least 2 weeks prior to dosing as per local and country-specific immunization guidelines for the appropriate age group.
  4. Anti-aquaporin-4 antibody-positive and diagnosis of NMOSD as defined by the 2015 International Panel for Neuromyelitis Optica Diagnosis criteria.
  5. Historical Relapse Rate of at least 2 relapses in the last 2 years, and with at least 1 relapse in the year prior to Screening.
  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.
  9. Male participants with a female spouse/partner of childbearing potential or a pregnant or breastfeeding spouse or partner must agree to use double barrier contraception (male condom plus appropriate barrier method for the female partner) while on treatment and for at least 5 months after the last dose of eculizumab.

  6. Use of rituximab or other biologicals such as tocilizumab within 6 months prior to Screening.
  7. Use of mitoxantrone within 3 months prior to Screening.
  8. Use of intravenous immunoglobulin or plasma exchange within 3 weeks prior to Screening.
