Clinical Trial Summary

This is a Phase I/II, first-in-human study consisting of four sequential parts and an open-label extension (OLE). The safety, tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) of single doses of crovalimab will be evaluated in healthy volunteers (HV) during part 1. The safety, tolerability, PK and PD of multiple doses of crovalimab will be evaluated in participants with paroxysmal nocturnal hemoglobinuria (PNH) in parts 2, 3, 4, and OLE of the study. Efficacy of crovalimab will be evaluated in Parts 2, 3, and 4.
