T-Cell-Depleted Allogeneic Stem Cell Transplantation After Immunoablative Induction Chemotherapy and Reduced-Intensity Transplantation Conditioning in Treating Patients With Hematologic Malignancies

OBJECTIVES:

Primary

• Determine engraftment in patients with hematologic malignancies treated with T-cell-depleted allogeneic stem cell transplantation after immunoablative induction chemotherapy and reduced-intensity transplantation conditioning.

Secondary

• Determine the incidence of acute graft-versus-host disease (GVHD), and nonrelapse mortality (within 100 days after transplantation) in these patients.
• Correlate levels of host immunosuppression before transplantation conditioning, as evaluated by peripheral blood CD4 counts, with graft rejection/failure within 100 days after transplantation and the level of donor hematopoietic chimerism 28 days after transplantation in these patients.
• Correlate donor-versus-recipient natural killer cell alloreactivity with graft rejection/failure, acute GVHD, and relapse of malignant disease in patients treated with this regimen.
• Determine the development of allospecific cytotoxic T-lymphocytes after transplantation in patients with myeloid or lymphoid leukemia.
• Correlate serum interleukin-7 and interleukin-15 levels with in vivo changes in host lymphocyte subpopulations in these patients during sequential immunoablative chemotherapy, before allogeneic stem cell transplantation, and during immune reconstitution after transplantation.

OUTLINE: This is a pilot study.

• Induction chemotherapy: Patients receive 1 of 2 induction chemotherapy regimens according to diagnosis. Patients with partial response or better after prior therapy (i.e., already adequately immune depleted) proceed directly to the transplantation preparative regimen.

• Regimen A (Hodgkin's lymphoma, non-Hodgkin's lymphoma [except lymphoblastic lymphoma], chronic lymphocytic leukemia, prolymphocytic leukemia, or multiple myeloma): Patients receive rituximab IV (if they have CD20+ B-cell malignancies) on day 1; fludarabine IV over 30 minutes on days 1-4; etoposide, doxorubicin, and vincristine IV continuously on days 1-4; cyclophosphamide IV over 30 minutes on day 5; oral prednisone on days 1-5; and filgrastim (G-CSF) subcutaneously (SC) beginning on day 6 and continuing until blood counts recover.
• Regimen B (lymphoblastic lymphoma, acute myeloid leukemia, acute lymphoblastic leukemia, refractory anemia with excess blasts, myeloproliferative disorders, chronic myelomonocytic leukemia, or chronic myelogenous leukemia): Patients receive G-CSF SC beginning 24 hours before initiating induction chemotherapy and continuing until blood counts recover. Patients also receive fludarabine IV over 30 minutes and cytarabine IV over 4 hours on days 1-5.

For both regimens, treatment repeats every 21 days for 1-2 courses. Patients who achieve remission or who have responsive or stable disease after induction chemotherapy then proceed to transplantation preparative regimen chemotherapy.

• Transplantation preparative regimen chemotherapy: Patients receive fludarabine IV over 30 minutes and cyclophosphamide IV over 2 hours on days -6 to -3.
• Graft-versus-host disease (GVHD) prophylaxis: Patients receive cyclosporine IV over 2 hours twice daily beginning on day -1 and continuing IV or orally until day 100. Patients with no acute GVHD at day 100 taper cyclosporine over 12 weeks.
• Allogeneic stem cell transplantation (SCT): Patients undergo T-cell-depleted allogeneic peripheral blood SCT on day 0. Patients receive G-CSF SC beginning on day 0 and continuing until blood counts recover.
• Donor lymphocyte infusion (DLI): Patients with persistent or progressive malignant disease after transplantation or mixed chimerism that does not improve after tapering or discontinuing immunosuppression therapy may receive DLI. DLI may be administered alone or in combination with chemotherapy. DLI repeats every 4 weeks until adequate donor chimerism is achieved or until GVHD develops.

Patients are followed at 28 and 100 days and then at 6, 9, 12, 18, and 24 months.

PROJECTED ACCRUAL: A total of 6-20 patients will be accrued for this study within 2 years.
