ALXN1210 (Ravulizumab) Versus Eculizumab in Complement Inhibitor Treatment-Naïve Adult Participants With Paroxysmal Nocturnal Hemoglobinuria (PNH)

Summary

The primary purpose of this study was to assess the noninferiority of ravulizumab compared to eculizumab in adult participants with PNH who had never been treated with a complement inhibitor (treatment-naïve).

Met primary endpoint

paper Ravulizumab demonstrated noninferior efficacy and comparable safety to eculizumab in two open-label, phase 3 studies in patients with paroxysmal nocturnal hemoglobinuria (PNH) who complement inhibitor-naive (Study 301) or were previously treated with eculizumab (Study 302). PMID 32869125 ↗
