Brief Summary:
The purpose of this study is to determine whether eculizumab long-term use is safe and effective in patients with relapsing NMO.

Condition or disease Intervention/treatment Phase
Neuromyelitis Optica Neuromyelitis Optica Spectrum Disorder Biological: eculizumab Phase 3

Detailed Description:
This study is an open label extension study to confirm the long term safety and efficacy of eculizumab in subjects with relapsing NMO who have completed the initial double-blind, randomized, placebo-controlled trial ECU-NMO-301.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 132 participants
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Phase III, Open-label, Extension Trial of ECU-NMO-301 to Evaluate the Safety and Efficacy of Eculizumab in Patients With Relapsing Neuromyelitis Optica (NMO)
Study Start Date : January 2015
Estimated Primary Completion Date : December 2018
Estimated Study Completion Date : December 2018

Arm Intervention/treatment
Experimental: Eculizumab
Eculizumab intravenous infusion every two weeks.
Biological: eculizumab
Other Name: Soliris

Primary Outcome Measures :
  1. Evaluate the long-term safety of eculizumab in patients with relapsing NMO. [ Time Frame: From first dose to study completion (maximum of 4 years). ]
    Treatment Emergent Adverse Events (TEAEs) and Serious Adverse Events (SAEs), change from baseline in vital signs, clinical laboratory tests, and suicide risk as assessed with Columbia-Suicide Rating Scale (C-SSRS)

Secondary Outcome Measures :
  1. Evaluate the long-term efficacy of eculizumab in patients with relapsing NMO [ Time Frame: From first dose to study completion (maximum of 4 years). ]
    Change from baseline in Annualized Relapsing Rate, disability, quality of life and neurologic function.

Other Outcome Measures:
  1. Describe the pharmacokinetics (PK) and pharmacodynamics (PD) of eculizumab in patients with relapsing NMO [ Time Frame: From first dose to study completion (maximum of 4 years). ]
    Change in plasma PK of eculizumab and in free C5 activity (PD marker) before and after treatment with the study drug.
