Donor Stem Cell Transplant in Treating Patients With Myeloid Cancer or Other Disease

Phase 2

Terminated

• Conditions: Leukemia; Myelodysplastic Syndromes
• Interventions: Biological: anti-thymocyte globulin; Drug: fludarabine phosphate; Drug: thiotepa; Procedure: peripheral blood stem cell transplantation; Radiation: total-body irradiation

• Registration Number: NCT00392782
• Lead Sponsor: Masonic Cancer Center, University of Minnesota

Brief Summary

RATIONALE: Giving total-body irradiation and chemotherapy, such as fludarabine and thiotepa, before a donor stem cell transplant helps stop the growth of cancer or abnormal cells. It also helps stop the patient's immune system from rejecting the donor's stem cells. When healthy stem cells from a donor are infused into the patient, they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells. Giving antithymocyte globulin and removing the T cells from the donor cells before transplant may stop this from happening.

PURPOSE: This phase II trial is studying how well a donor stem cell transplant works in treating patients with myeloid cancer or other disease.

Detailed Description

OBJECTIVES:

Primary

* Determine the incidence of disease-free survival at 1 year in patients with acute or chronic myeloid leukemias undergoing T-cell-depleted hematopoietic stem cell transplantation from HLA-C mismatched, unrelated donors.

Secondary

* Determine the incidence of disease relapse at 1 year in patients treated with this regimen.

* Determine the incidence and severity of acute graft-vs-host disease (GVHD) at 100 days and chronic GVHD at 1 year in these patients.

* Determine the incidence of graft failure at day 100.

* Determine the transplant-related mortality of these patients at 1 year.

* Determine the overall survival of these patients at 1 year.

OUTLINE: This is a prospective, multicenter study. Patients are stratified according to killer-cell immunoglobulin-like receptors (KIR) epitope mismatch (yes \[experimental\] vs no \[control\]).

* Myeloablative preparative regimen: Patients undergo total body irradiation twice daily on days -10 and -9 and receive thiotepa intravenously (IV) over 4 hours on days -8 and -7, fludarabine phosphate IV over 30-60 minutes on days -7 to -3, and antithymocyte globulin IV over 4-6 hours on days -5 to -2.

* Allogeneic peripheral blood stem cell (PBSC) transplantation: Patients undergo filgrastim (G-CSF)-mobilized, T-cell-depleted, CD34+-selected allogeneic PBSC transplantation on day 0.

After completion of study treatment, patients are followed periodically for at least 1 year.

Inclusion Criteria

• Primary acute myeloid leukemia (AML)

  • First complete remission (CR) with high risk features as defined by: failure to achieve remission by day 21 after induction chemotherapy, or the presence of chromosomal abnormalities involving any of the following: -5/de (5q), -7/del(7q), inversion 3q, abnormalities of 11q23, 20q, 21q, del(9q), translocation 6;9, translocation 9;22, abnormalities of 17p, or complex karyotype with > or = 3 abnormalities. Complete remission is defined as < 5% blasts in the marrow.
  • Second CR or subsequent in remission
  • Refractory or relapsed disease with absolute peripheral blood blasts < 2000/mcL

• Secondary AML in remission or relapse

• Chronic myelogenous leukemia (CML) in accelerated or blast phase

  • Accelerated phase is defined by any one of the following:

    • Blasts 10% to 19% of peripheral blood white cells or bone marrow cells
    • Peripheral blood basophils at least 20%
    • Persistent thrombocytopenia (<100 x 10^9/L) unrelated to therapy, or persistent thrombocytosis (>1000 x 10^9/L) unresponsive to therapy
    • Increasing spleen size and increasing white blood cell (WBC) count unresponsive to therapy
    • Cytogenetic evidence of clonal evolution (i.e., the appearance of an additional genetic abnormality that was not present in the initial specimen at the time of diagnosis of chronic phase CML)
    • Resistance to tyrosine kinase inhibitors (imatinib or other) defined as no complete cytogenetic response even if the above criteria are not met.

  • Blast phase is defined by either of the following:

    • Blasts 20% or more of peripheral blood white cells or bone marrow cells
    • Extramedullary blast proliferation
    • Large foci or clusters of blasts in bone marrow biopsy

• Secondary MDS with any international prostate symptom score (IPSS)

• Age ≤60 years

• Co-Morbidity score 0-2

• At least 35 days following start of preceding leukemia induction therapy
