Intervention arm for Graft-versus-Host Disease
Study Summary
Graft-vs-host disease (GVHD) causes substantial mortality, morbidity and poor quality of life after blood or marrow transplantation (BMT). In Alberta, we use antithymocyte globulin (ATG, given on days -2, -1 and 0) in addition to methotrexate and cyclosporine for GVHD prophylaxis. In spite of that, ~40% patients develop significant GVHD (grade 2-4 acute GVHD or chronic GVHD needing systemic immunosuppressive therapy). ATG at the dose we typically use (4.5 mg/kg) is relatively non-toxic. At higher doses, ATG could increase the likelihood of posttransplant infections or relapse. Thus an extra dose of ATG (on top of the routine 4.5 mg/kg) might be justified only for patients at high risk of developing significant GVHD. In our experience, low serum level of interleukin-15 (IL15) and high serum level of interleukin-2 receptor alpha (IL2Ra) on day 7 predict development of significant GVHD. Here we will test whether, compared to historical/concurrent controls, an extra dose of ATG (3 mg/kg on day 8) given to patients with low IL15 or high IL2Ra on day 7 reduces the incidence of significant GVHD, and improves survival free of relapse and GVHD, and quality of life.
