Less Chronic Graft-Versus-Host Disease, Immunosuppressive Therapy and Better Survival after Anti-Thymocyte Globulin in Unrelated Donor Stem Cell Transplant Recipients: Longer Follow-up of a Multicentre Cell Therapy Transplant Canada Randomized Trial

Background: We previously reported that pretreatment with rabbit anti-thymocyte globulin (ATG) decreases the use of immunosuppressive therapy (IST) and occurrence of chronic graft-versus-host disease (GVHD) 12 months after allogeneic stem cell transplantation from unrelated donors. We hypothesized these benefits would persist beyond 12 months with a positive clinical impact on patients. Methods: Phase 3, multicentre, …
