RATIONALE: Giving chemotherapy and total body irradiation before a donor bone marrow transplant helps stop the growth of cancer and abnormal cells and helps stop the patient's immune system from rejecting the donor's stem cells. When the 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 total-body irradiation and chemotherapy followed by T-cell depleted donor bone marrow transplant works in treating young patients with hematologic cancer.
|Condition or disease||Intervention/treatment||Phase|
|Leukemia Lymphoma Myelodysplastic Syndromes Myelodysplastic/Myeloproliferative Neoplasms||Biological: anti-thymocyte globulin Biological: filgrastim Drug: cyclophosphamide Drug: fludarabine phosphate Drug: thiotepa Procedure: allogeneic bone marrow transplantation Radiation: radiation therapy||Phase 2|
- Determine the efficacy of hyperfractionated total body irradiation, thiotepa, and cyclophosphamide followed by T-cell-depleted allogeneic bone marrow transplantation in children with acute myeloid leukemia, acute lymphoblastic leukemia, chronic myelogenous leukemia, non-Hodgkin's lymphoma, or myelodysplastic syndromes.
- Correlate the progenitor cell dose and dose of clonable T cells with the incidence and quality of engraftment, extent of chimerism, incidence and severity of acute and chronic graft-versus-host disease, characteristics of hematopoietic and immunologic reconstitution, and overall and disease-free survival at 2 years in patients treated with this regimen.
OUTLINE: Patients undergo total body irradiation three times daily on days -9 to -7 and twice on day -6. Patients receive thiotepa IV over 4 hours on days -5 and -4 and cyclophosphamide IV over 30 minutes on days -3 and -2. Patients who cannot receive cyclophosphamide, due to prior hemorrhagic cystitis or exposure to high-dose cyclophosphamide or ifosfamide, receive fludarabine IV over 30 minutes on days -5 to -1. Patients planning to receive family member HLA-mismatched or unrelated bone marrow transplantation receive horse anti-thymocyte globulin IV once daily on days -5 and -4. Patients undergo allogeneic T-cell-depleted bone marrow transplantation on day 0. Patients receive filgrastim (G-CSF) IV every 12 hours beginning on day 7 and continuing until blood counts recover.
Patients are followed every 2-4 weeks for the first 100 days post-transplantation, every 6 weeks for 6 months, every 3 months for 1 year, and then every 3-6 months until 2 years post-transplantation.
PROJECTED ACCRUAL: A total of 50 patients (25 with HLA 6/6 antigen-matched related donors and 25 with HLA 5/6 antigen-matched related donors or HLA 5/6 or 6/6 antigen-matched unrelated donors) will be accrued for this study within 3 years.

|Official Title:||Phase II Trial of T-Cell Depleted Hematopoietic Stem Cell Transplants (SBA-E-BM) From HLA Compatible Related or Unrelated Donors After a Myeloablative Preparative Regimen of Hyperfractionated TBI, Thiotepa and Cyclophosphamide (TBI/Thio/cy) for Treatment of Patients Less Than or Equal to 18 Years With Lymphohematopoietic Disorders|

|Actual Study Completion Date :||June 2008|
Experimental: Pts < than or = 18 years with lymphohematopoietic disorders
This is a phase II, single-center study to evaluate a cytoreductive regimen of hyperfractionated TBI, thiotepa and cyclophosphamide (HFTBI/thio/cy) followed by infusions of SBA-E- T-cell depleted marrow in pediatric leukemia recipients of either HLA-identical or HLA-1Ag non-identical related or unrelated donors.
|Biological: anti-thymocyte globulin Biological: filgrastim Drug: cyclophosphamide Drug: fludarabine phosphate Drug: thiotepa Procedure: allogeneic bone marrow transplantation Radiation: radiation therapy|
- Minimal transplantation related mortality [ Time Frame: 2 years ]
- High disease-free survival at 2 years [ Time Frame: 2 years ]
