Jazz enrolls First Patient in Phase 2 Clinical Trial evaluating Defibrotide

Jazz Pharmaceuticals asserted the enrollment of patients in a Phase 2 Clinical Trial evaluating the efficacy and safety of defibrotide for the prevention of acute Graft-versus-Host-Disease (aGvHD) in adult and pediatric patients after allogeneic hematopoietic stem cell transplant (HSCT).

Karen Smith, M.D., Ph.D., executive vice president, research and development and chief medical officer at Jazz Pharmaceuticals said “Despite the use of current immunoprophylaxis strategies, Graft-versus-Host Disease remains a leading cause of non-relapse mortality after allogeneic stem cell transplant. Jazz is committed to advancing our understanding of how defibrotide may address this unmet need.”

The Phase 2 clinical trial is a prospective, randomized, open-label study of the efficacy and safety of defibrotide added to standard of care immunoprophylaxis for the prevention of aGvHD, compared to the standard of care alone. Jazz expects to enroll approximately 150 adult and pediatric patients who have undergone allogeneic HSCT from an unrelated donor. The primary endpoint is cumulative incidence of Grade B-D aGvHD by day +100 post-allogeneic HSCT.
