Trial Outcomes & Findings for Phase 2 Trial of Prophylactic Rituximab Therapy for Prevention of CGVHD (NCT NCT00186628)

NCT ID: NCT00186628

Last Updated: 2017-11-28

Results Overview

The cumulative percentage of participants who develop chronic graft-vs-host disease (cGvHD). Chronic cGvHD was defined as at least one instance of a clinically-accepted marker for cGvHD (see Filipovich, et al. Biology of Blood and Marrow Transplantation. 2005;11:945-955)
