Detailed Description
This is a Phase 3b, single-arm, open-label, multicenter study to evaluate the efficacy, safety, pharmacokinetics (PK), pharmacodynamics (PD), and immunogenicity of eculizumab in adult participants with PNH in China who previously have not been treated with complement inhibitors. Approximately 25 eligible participants in China will be enrolled.
