Primary outcomePrimary: Percentage of Patients Who Are Able to Receive at Least One DLI Treatment — 36 Participants

Summary

This pilot phase II trial studies how well giving donor T cells after donor stem cell transplant works in treating patients with hematologic malignancies. In a donor stem cell transplant, the donated stem cells may replace the patient's immune cells and help destroy any remaining cancer cells (graft-versus-tumor effect). Giving an infusion of the donor's T cells (donor lymphocyte infusion) after the transplant may help increase this effect.

Eligibility Criteria

Inclusion Criteria

  • INCLUSION CRITERIA PRIOR TO TRANSPLANT:
  • The clinical trial will be offered to all high risk (defined 3 below) patients with hematologic malignancies who require stem cell transplants as part of their standard of care using matched related or unrelated donors
  • Patients with high risk myeloid or lymphoid malignancies at stem cell transplant following American Society for Blood and Marrow Transplantation (ASBMT) criteria, including but not limited to conditions listed; these criteria apply BEFORE cyto-reductive therapy given within 28 days of planned conditioning:
  • Refractory acute myelogenous or lymphoid leukemia
  • Relapsed acute myelogenous or lymphoid leukemia
  • Myelodysplastic syndromes with 5% or more blasts
  • Chronic myelogenous leukemia in chronic phase 3 or more, blast phase presently, or second accelerated phase
  • Recurrent or refractory malignant lymphoma or Hodgkin's disease with less than a partial response at transplant
  • High risk chronic lymphocytic leukemia defined as no response or stable disease to the most recent treatment regimen
  • DONORS: Matched related or unrelated donor stem cell transplant (SCT) matched at human leukocyte antigen (HLA) A- B, C, and DRB1 by molecular methods; 7 of 8 matched donor acceptable for related donors
  • T-cell depletion with anti-thymocyte globulin (ATG) (rabbit or horse) or at least 30 mg of alemtuzumab total in the conditioning regimen
  • Immune suppression; planned post-transplant immune suppression should include tacrolimus or cyclosporin monotherapy (i.e., calcineurin inhibitor or CN) for alemtuzumab regimens and a second immune suppressant for ATG treated patients; other agents may be used if CN intolerance or toxicity occurs post-transplant
  • Zubrod performance status (PS) 0-2 or equivalent Karnofsky PS
  • Eligible for allogeneic transplant in the treating physicians' judgment and by institutional standards
  • ELIGIBILITY TO RECEIVE DLI POST-TRANSPLANT:
  • Donor lymphocytes available or able to be collected
  • No evidence of disease by standard morphology; minimal residual disease or molecular evidence of disease will not exclude
  • Absolute neutrophil count >= 500/μl
  • Platelet count >= 20, 000/μl without transfusion for 7 days
  • Serum glutamic oxaloacetic transaminase (SGOT) and serum glutamate pyruvate transaminase (SGPT) = = 2.0 mg/dL
  • SGOT and SGPT >= 5 x ULN; liver biopsy preferred for such patients
  • Bilirubin >= 3 x ULN (unless Gilbert's syndrome)
  • Diffusing capacity of the lung for carbon monoxide (DLCO) < 50% corrected for hemoglobin
  • Left ventricular ejection fraction or shortening fraction < 40%
  • Unlikely to be able to procure additional donor lymphocytes
