Outcome

Met primary endpoint

registry analysis (superiority test); Pegcetacoplan to Pegcetacoplan vs Eculizumab to Pegcetacoplan; p <0.0001; LS mean difference 3.84 (95% CI 2.33 to 5.34); NCT03500549 ↗

paper Pegcetacoplan was superior to eculizumab with respect to the change in hemoglobin level from baseline to week 16, with an adjusted (least squares) mean difference of 3.84 g per deciliter (P<0.001). PMID 33730455 ↗
