Safety and Efficacy Study of OMS721 in Patients With Thrombotic Microangiopathies

Thrombotic Microangiopathies Clinical Trial

Official title:
A Phase 2, Uncontrolled, Three-Stage, Dose-Escalation Cohort Study to Evaluate the Safety, Pharmacokinetics, Pharmacodynamics, Immunogenicity, and Clinical Activity of OMS721 in Adults With Thrombotic Microangiopathies

Clinical Trial Summary

The purpose of this study is to assess the safety, efficacy, pharmacokinetics (PK), pharmacodynamics (PD), and immunogenicity of OMS721 in patients with thrombotic microangiopathies (TMA).

Clinical Trial Description

This is a Phase 2, uncontrolled, 3-stage, ascending-dose-escalation study in patients with 1 of 3 forms of TMA: atypical hemolytic uremic syndrome (aHUS), thrombotic thrombocytopenia (TTP), and hematopoietic stem cell transplant - associated TMA (HSCT-associated TMA). In Stage 1 of the study, OMS721 was administered to 3 cohorts, with dose escalation by cohort to identify the optimal dosing regimen. In Stage 2, the dose selected in the first stage was administered to expanded cohorts of patients with distinct etiologies (aHUS alone in 1 cohort and TTP or HSCT-TMA in the other cohort). Patients completing Stage 2 were eligible for continued treatment in Stage 3 if they tolerated OMS721 treatment and derived clinical benefit. Enrollment in the study has been completed. ;
