[0138] Example 1. Efficacy and safety of eculizumab in adult patients with neuromyelitis optica spectrum disorder (NMOSD)

[0139] 1. Research Design

[0140] 1.1. Overall Design

[0141] This is a Phase 3, external placebo-controlled, open-label, multicenter study to evaluate the efficacy and safety of eculizumab in adult patients with NMOSD. Approximately 55 eligible adult patients with NMOSD from North America, Europe, Asia Pacific and Japan participated in the study.

[0142] The study had 4 periods: the screening period, the main treatment period, the long-term extension period, and the safety follow-up period ( figure 1 ). During the screening period, patients are screened for eligibility for up to 6 weeks. When all patients completed the Week 26 visit or terminated early and then completed their end of primary treatment period (EOPT) visit, the primary treatment period ended and the long-term extension period began. All patients continued to receive eculizumab for ...
