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

Status Withdrawn

Clinical Trial Summary

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.

Clinical Trial 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. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
