Flu/TBI in Treating Patients Not Responding to Previous Hormone Therapy

May 31, 2012 updated by: OHSU Knight Cancer Institute

Pilot Trial of Non-Myeloablative Allogeneic Hematopoietic Stem Cell Transplantation for the Treatment of Patients With Hormone-Refractory Prostate Cancer

RATIONALE: Giving low doses of chemotherapy, such as fludarabine, and radiation therapy before a donor 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). 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 transplant may stop this from happening.

PURPOSE: This phase II trial is studying how well giving fludarabine together with total-body irradiation works in treating patients who are undergoing a donor stem cell transplant for progressive metastatic prostate cancer that has not responded to previous hormone therapy.

Detailed Description

OBJECTIVES:

  • Determine the treatment-related mortality in patients with hormone-refractory, progressive metastatic prostate cancer treated with nonmyeloablative conditioning comprising fludarabine and total-body irradiation followed by allogeneic hematopoietic stem cell transplantation.

OUTLINE:

  • Nonmyeloablative conditioning regimen: Patients receive fludarabine IV on days -4 to -2 and total-body irradiation (TBI) on day 0.
  • Allogeneic hematopoietic stem cell transplantation (AHSCT): After TBI, patients undergo AHSCT on day 0.
  • Immunosuppression: Patients receive oral cyclosporine twice daily on days -3 to 56 followed by a taper until day 81. Patients also receive oral mycophenolate mofetil twice daily on days 0-27 (if patient has a related donor) OR three times daily on days 0-29 and then twice daily on days 30-149 followed by additional tapering until day 180 (if patient has an unrelated donor).

PROJECTED ACCRUAL: A total of 10 patients will be accrued for this study.
