Acute graft-versus-host disease (aGVHD) is a major cause of morbidity and mortality in patients undergoing unrelated hematopoietic stem cell transplantation. We prospectively evaluated the efficacy of intermediate-dose rabbit anti-thymocyte globulin (Thymoglobulin (R) a total of 4.5 mg/kg given over days -3, -2, and -1) in combination with tacrolimus and sirolimus for the prevention of aGVHD. We enrolled 47 recipients who underwent unrelated hematopoietic stem cell transplantation. Patients received daily granulocyte colony-stimulating factor starting on day +6 until neutrophil engraftment (median duration, II days; range, 9-15 days). Twenty-two patients received HLA 8/8 and 25 received 7/8 matched grafts, respectively. The median follow-up duration was 23.6 months (range, 18.8-27.9 months). The cumulative incidence of grade II to IV aGVHD was 23.4% (95% confidence interval, 12.4-36.3). At 2-year follow-up, the cumulative incidence of nonrelapse mortality was 31.9%, cumulative incidence of relapse was 24.6%, and cumulative incidence of chronic GVHD was 33%. Progression-free survival at I year was 54%, with a median of 17.7 months. Overall survival at 1 year was 65%, with no median reached. These results suggest that the combination of Thymoglobulin, tacrolimus, and sirolimus in patients undergoing unrelated hematopoietic stem cell transplantation is well tolerated and associated with a low incidence and severity of aGVHD and chronic graft-versus-host disease.
