Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The primary (most important) objectives of this study are to determine:
Whether Eculizumab reduces relapse frequency in patients with relapsing NMO. The number of attacks during the one year treatment period will be compared to the number of attacks that occurred prior to initiation of eculizumab treatment. For patients with more than 2 year disease duration, the average number of attacks in the preceding 2 years will be calculated. For patients with less than 2 years disease duration the number of attacks in the preceding year will be used.
The safety profile of eculizumab in patients with NMO.
The secondary objectives are to determine:
Whether eculizumab maintains or improves walking, visual function and quality of life as measured by a variety of established disability scales. We will also assess the severity of an individual attack and the degree of recovery.
How the drug behaves in the patient's blood (called pharmacodynamics and pharmacokinetics).
Depending on our preliminary investigations we may evaluate patient cerebrospinal fluid in the laboratory to see how effective eculizumab is at getting into the cerebrospinal fluid from the blood stream, and to see if the drug reverses the biological effects of the NMO-IgG antibody.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Eculizumab
The patient will receive eculizumab at a dose of 600mg intravenously (an infusion given into the vein) each week for 4 weeks, then 900mg intravenously at the fifth week, then 900mg every 2 weeks for 48 weeks. Subjects will receive therapy for a total of 12 months.
Eculizumab
The patient will receive eculizumab at a dose of 600mg intravenously (an infusion given into the vein) each week for 4 weeks, then 900mg intravenously at the fifth week, then 900mg every 2 weeks for 48 weeks.
The first infusion will be given at Mayo Clinic site; subsequent infusions will be administered in the subject's home by a company which will send a nurse to administer the infusion. Subjects will receive therapy for a total of 12 months.

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
2. Clinical evidence of at least 2 relapses in last 6 months or 3 relapses in the last 12 months (with at least 1 relapse occurring in the preceding 6 months).
3. Age ≥18 years
4. Corrected visual acuity 20/100 or better in at least one eye. If fails item # 4 then entry allowed but only if last attack was myelitis and only attacks of myelitis are considered as outcome measurement.
5. Ambulatory (with or without walker). If fails item # 5 then entry allowed but only if last attack was ON and only attacks of ON are considered as outcome measurement.
6. Provision of written informed consent (see attached) to participate in the study.
7. N. meningitidis vaccination at least 14 days prior to receiving the first eculizumab infusion. If patient in midst of an acute relapse, then relapse will be treated with standard therapy and vaccination given only after a minimum of 4 weeks post attack onset.
Exclusion Criteria
1. Progressive neurological deterioration unrelated to relapses of ON or myelitis.
2. Pregnant, breastfeeding, or intending to conceive during the course of the study
3. Patients will not participate in any other clinical therapeutic study or will not have participated in any other experimental treatment study within 30 days of screening
4. Patients with a history of splenectomy, because of a potential increased risk of developing meningococcal infection.
