Clinical Trial: Pentostatin and Donor White Blood Cells in Preventing Graft Rejection in Cancer Patients Who Have Undergone Donor Stem Cell Transplantation

This study is currently recruiting patients.

Sponsors and Collaborators: Fred Hutchinson Cancer Research Center
National Cancer Institute (NCI)
Information provided by: National Cancer Institute (NCI)


RATIONALE: Peripheral stem cell transplantation may be able to replace immune cells that were destroyed by radiation therapy or chemotherapy used to kill cancer cells. Infusions of donor white blood cells may decrease the body's rejection of the transplanted peripheral stem cells. Pentostatin, mycophenolate mofetil, and cyclosporine may also prevent this from happening.

PURPOSE: This phase I/II trial is studying the side effects of pentostatin and donor white blood cells and to see how well they work in preventing graft rejection in cancer patients who have undergone a donor stem cell transplantation.

Official Title: Phase I/II Study of Pentostatin and Donor Lymphocyte Infusion in Preventing Graft Rejection in Cancer Patients With Low or Falling Donor T-Cell Chimerism After Nonmyeloablative Allogeneic Stem Cell Transplantation

Further Study Details: 



  • Determine the incidence of graft-vs-host disease in patients treated with this regimen.
  • Determine the incidence of infections in patients treated with this regimen.
  • Determine disease response in patients with persistent disease treated with this regimen.

OUTLINE: This is a multicenter study.

Patients receive pentostatin IV over a few seconds or 20-30 minutes on day -2 and donor lymphocytes IV over 15-30 minutes on day 0. Treatment may repeat once beginning at least 28 days later. Patients are evaluated once 20 patients have been treated. If this regimen is found to be ineffective, subsequent patients receive pentostatin and donor lymphocytes as before, as well as oral cyclosporine twice daily beginning on day -3 and continuing until day 56. Patients also receive oral mycophenolate mofetil once daily beginning on day 0 and continuing until day 27.

Patients are followed monthly for 3 months, every 3 months for 6 months, every 6 months for 2 years, and then annually thereafter.

PROJECTED ACCRUAL: A total of 20-80 patients will be accrued for this study.
