Summary
The purpose of the study is to evaluate the safety and efficacy of zilucoplan (RA101495) in patients with Paroxysmal Nocturnal Hemoglobinuria (PNH). There will be two groups of patients in the study: the first group will include patients who have never received eculizumab for treatment of PNH. The second group will include patients who have received treatment with eculizumab for at least 6 months prior to the study. Patients will be treated with RA101495 for 12 weeks.
Eligibility Criteria
Inclusion Criteria
- Diagnosis of PNH by flow cytometry

- For patients who previously received eculizumab: subjects must have received treatment with eculizumab for at least 6 months prior to Screening
Exclusion Criteria
- History of meningococcal disease
- Current systemic infection or suspicion of active bacterial infection
