Clinical Trial Summary

The purpose of this study is to evaluate the platelet count change from baseline and safety of OMS721 in adults and adolescents with atypical hemolytic uremic syndrome (aHUS). The study will also evaluate pharmacokinetics (PK), pharmacodynamics (PD), and anti-drug antibody response (ADA).


Clinical Trial Description

This is a Phase 3, multicenter study of OMS721 in adults and adolescents with atypical hemolytic uremic syndrome (aHUS). The uncontrolled, open-label study will evaluate the effect of OMS721 in subjects with plasma therapy-resistant aHUS and plasma therapy-responsive aHUS. This study has four periods: Screening, Treatment Induction, Treatment Maintenance, and Follow-up. Approximate enrollment is 80 subjects. An interim analysis will be performed after 40 subjects have completed 26 weeks of treatment for potential registration. ;
