Summary

RATIONALE: Giving low doses of chemotherapy, such as fludarabine and busulfan, before a donor peripheral blood stem cell transplant helps stop the growth of cancer cells. It also stops the patient's immune system from rejecting the donor's stem cells. The donated stem cells may replace the patient's immune system 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. Sometimes the transplanted cells from a donor can also make an immune response against the body's normal cells. Giving cyclosporine and mycophenolate mofetil after the transplant may stop this from happening. PURPOSE: This phase I/II trial is studying the side effects of giving busulfan and fludarabine together with total-body irradiation and to see how well they work in treating patients who are undergoing a donor stem cell transplant for hematologic cancer.

Clinical Details

Official title: A Phase I/II Non-Myeloablative Allogeneic Hematopoietic Stem Cell Transplant for the Treatment of Patients With Hematologic Malignancies Using Busulfan, Fludarabine and Total Body Irradiation

Study design: Intervention Model: Single Group Assignment, Masking: Open Label, Primary Purpose: Treatment

Primary outcome:

Safety

Non-relapse mortality

Detailed description: OBJECTIVES: Primary

- To assess safety and toxicity of the addition of busulfan added to an established

fludarabine and low-dose total-body irradiation (TBI) conditioning regimen for non-myeloablative allogeneic transplantation in patients with hematologic malignancies. (Phase I)

- To assess the non-relapse mortality 1-year after conditioning with busulfan and

fludarabine/TBI in patients with hematologic malignancies at moderate to high risk for graft rejection and/or relapse of underlying disease. (Phase II) Secondary

- To assess overall survival 1-year survival. (Phase II)

- To assess the incidence of graft rejection. (Phase II)

- To assess the incidence of grade II-IV acute graft-vs-host disease (GVHD) and chronic

extensive GVHD. (Phase II)

- To assess rates of disease progression and/or relapse-related mortality. (Phase II)

- To determine non-hematologic grade III-IV organ specific toxicity. (Phase II)

OUTLINE:

- Nonmyeloablative-conditioning regimen: Patients receive busulfan IV on day -5 and

fludarabine IV over 30 minutes on days - 4 to -2. Patients undergo total body

irradiation on day 0.

- Allogeneic peripheral blood stem cell transplantation (PBSC): Patients undergo donor

PBSC infusion on day 0.

- Graft-versus-host disease prophylaxis: Patients receive oral cyclosporine twice daily

on days - 3 to 56 followed by a taper to day 180. Patients with a related stem cell

donor receive oral mycophenolate mofetil twice daily on days 0-28. Patients with an unrelated stem cell donor receive oral mycophenolate mofetil 3 times daily on days 0-28 followed by a taper twice daily to day 56. Patients with evidence of relapse or persistent disease may also receive up to 3 donor lymphocyte infusions. PROJECTED ACCRUAL: A total of 225 patients will be accrued for this study; 25 patients accrued into the Phase I and 200 patients into Phase II.
