Total-Body Irradiation, Thiotepa, and Fludarabine in Treating Young Patients Who Are Undergoing a Donor Stem Cell Transplant for Hematologic Cancer

17. september 2010 opdateret af: Fred Hutchinson Cancer Center

A Phase I/II Study of Total Body Irradiation, Thiotepa, and Fludarabine as Conditioning for Haploidentical CD34+ Purified Peripheral Blood Stem Cell Transplants

RATIONALE: Chemotherapy, such as fludarabine and thiotepa, and radiation therapy may destroy cancerous blood-forming cells (stem cells) in the blood and bone marrow. Giving healthy stem cells from a donor whose blood closely resembles the patient's blood will help the patient's bone marrow make new stem cells that become red blood cells, white blood cells, and platelets.

PURPOSE: This phase I/II trial is studying the side effects of total-body irradiation, fludarabine, and thiotepa and to see how well they work in treating young patients who are undergoing a donor stem cell transplant for hematologic cancer.

Detaljeret beskrivelse

OBJECTIVES:

Primary

  • Determine the safety of a conditioning regimen without anti-thymocyte globulin comprising total body irradiation, thiotepa, and fludarabine followed by CD34-positive-selected haploidentical allogeneic peripheral blood stem cell transplantation in young patients with life-threatening hematologic malignancies.

Secondary

  • Determine the risk for severe graft-vs-host disease in patients treated with this regimen.
  • Determine the kinetics of immune reconstitution in patients treated with this regimen.
  • Determine the risk for life-threatening infections in patients treated with this regimen.

OUTLINE:

  • Conditioning regimen: Patients 7 years of age and under undergo total body irradiation twice daily on days -9 to -7. Patients over 7 years of age undergo total body irradiation once on day -7. All patients receive fludarabine IV once daily on days -6 to -2 and thiotepa IV over 2 hours twice on day -5.
  • CD34-positive (CD34+)-selected haploidentical allogeneic peripheral blood stem cell transplantation (PBSCT): Patients undergo CD34+-selected allogeneic PBSCT on days 0 and 2.

Patients with acute lymphoblastic leukemia or CNS disease also receive methotrexate intrathecally twice before transplantation and 4 times after day 35 post-transplantation. Male patients with lymphoid malignancies undergo additional radiotherapy to the testes.

After completion of study treatment, patients are followed for at least 100 days, at 1 year, and then periodically thereafter.

PROJECTED ACCRUAL: A total of 20 patients (10 patients ≤ 7 years of age and 10 patients > 7 years of age) will be accrued for this study within 3 years.
