Official Title: Multicenter Trials to Evaluate the Efficacy and Toxicity of Sirolimus/Tacrolimus Combination as a GVHD Prophylaxis After HLA Matched Related PBSCT

Brief Summary:

Study Design: To evaluate the efficacy of the combination of sirolimus and tacrolimus as a graft-versus-host disease prophylaxis, the investigators are going to perform a phase II, multicenter clinical trial after human leukocyte antigen (HLA)-matched, related peripheral blood stem cell transplants (PBSCT) in patients with hematologic malignancies. Total 116 patients will be accrued.

Objective: The primary objective is to evaluate the rates of 100 day Grade II-IV acute GVHD. Secondary objectives include the time to neutrophil and platelet engraftment, the incidence of grade III-IV acute GVHD, non-relapse mortality during 100 days after transplant, mucositis severity, all infectious complications including cytomegalovirus (CMV) reactivation, vascular complications (venoocclusive disease of liver; VOD, thrombotic microangiopathy; TMA), disease-free survival, and overall survival at 1 year after transplant.

Eligibility Criteria: Eligible patients are between 20 and 60 years of age, have acute leukemia, myelodysplastic syndrome (MDS), chronic myelogenous leukemia (CML), and adequate organ function. For available sibling donor, a serologic (or higher resolution) 6/6 Class I HLA-A and B and molecular Class II DRB1 must be matched.

Treatment Description: Conditioning regimens will vary by center and donor will donate peripheral blood stem cells according to local institutional practices. Peripheral blood stem cells will not be manipulated or T-depleted prior to infusion. Tacrolimus will be administered at 0.05 mg/kg/day intravenously by continuous infusion beginning on day -1 with a target serum concentration of 5 to 10 ng/mL. Sirolimus will be administered as a 6 mg oral loading dose on day -1, followed by a 3 mg/day single dose, with a target serum concentration of 3 to 12 ng/mL
