Cyclophosphamide and/or Mycophenolate Mofetil With or Without Tacrolimus in Treating Patients Who Are Undergoing a Donor Bone Marrow or Peripheral Stem Cell Transplant for Hematologic Cancer
Summary
RATIONALE: Giving low doses of chemotherapy, such as fludarabine, and radiation therapy before a donor bone marrow or 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 cyclophosphamide, mycophenolate mofetil, and tacrolimus after transplant may stop this from happening.
PURPOSE: This phase I trial is studying cyclophosphamide and/or mycophenolate mofetil with or without tacrolimus to see which is the best regimen in treating patients who are undergoing a donor bone marrow or stem cell transplant for hematologic cancer.
Description
OBJECTIVES:
- Determine a minimal (short-duration) post-transplant immunosuppression regimen comprising cyclophosphamide and/or mycophenolate mofetil with or without tacrolimus that results in ≤ 20% incidence of grade II or higher acute graft-versus-host disease (GVHD) in patients with hematologic malignancies undergoing nonmyeloablative allogeneic bone marrow or peripheral blood stem cell transplantation from an HLA-identical related donor.
- Determine the post-transplant immunosuppression regimen that results in < 10% incidence of nonengraftment, defined as < 5% donor chimerism in peripheral blood at day 60, in these patients.
- Determine the incidence and severity of acute GVHD in patients treated with these regimens.
- Determine the frequency of mixed chimerism in patients treated with these regimens.
OUTLINE:
- Nonmyeloablative allogeneic bone marrow transplantation (BMT) or peripheral blood stem cell transplantation (PBSCT): Patients receive fludarabine IV on days -4 to -2 and undergo total-body irradiation on day -1. Patients undergo allogeneic BMT on day 0 or PBSCT on day 0 (and days 1 and 2, if needed). Patients receive filgrastim (G-CSF) beginning on day 5 and continuing until at least day 15 or until blood counts recover.
- Sequentially increasing levels of post-transplant immunosuppression: Cohorts of patients are enrolled into 1 of the following regimens:
- Regimen 1 (post-BMT immunosuppression): Patients receive cyclophosphamide IV on day 3 only.
- Regimen 2 (post-BMT immunosuppression): Patients receive mycophenolate mofetil (MMF) once on day 3 and then twice daily on days 4-32.
- Regimen 3 (post-BMT immunosuppression): Patients receive cyclophosphamide IV on days 3 and 4 and MMF twice daily on days 4-33.
- Regimen 4 (post-PBSCT immunosuppression): Patients receive cyclophosphamide and MMF as in regimen 3.
- Regimen 5 (post-PBSCT immunosuppression): Patients receive cyclophosphamide and MMF as in regimen 3 and tacrolimus twice daily on days 4-33.
Cohorts of approximately 10-20 patients receive sequentially increasing levels of post-transplant immunosuppression until a minimal (short-duration) post-transplant immunosuppression regimen is identified. The minimal post-transplant immunosuppression regimen is defined as the regimen in which ≤ 3 of 10 or ≤ 6 of 20 patients develop grade II or higher acute graft-versus-host disease AND ≤ 2 of 10 or ≤ 4 of 20 patients fail to engraft 60 days post-transplantation. Once the minimal post-transplant immunosuppression regimen is identified, an additional 10 patients are treated with that regimen.
Patients are followed for 60 days after transplantation.
PROJECTED ACCRUAL: A total of 60 patients will be accrued for this study.

Medical and Biotech [MESH] Definitions
Tacrolimus Binding Protein 1a
A 12-KDa tacrolimus binding protein that is found associated with and may modulate the function of calcium release channels. It is a peptidyl-prolyl cis/trans isomerase which is inhibited by both tacrolimus (commonly called FK506) and SIROLIMUS.
Tacrolimus Binding Proteins
A family of immunophilin proteins that bind to the immunosuppressive drugs TACROLIMUS (also known as FK506) and SIROLIMUS. EC 5.2.1.-
Cyclophosphamide
Precursor of an alkylating nitrogen mustard antineoplastic and immunosuppressive agent that must be activated in the LIVER to form the active aldophosphamide. It has been used in the treatment of LYMPHOMA and LEUKEMIA. Its side effect, ALOPECIA, has been used for defleecing sheep. Cyclophosphamide may also cause sterility, birth defects, mutations, and cancer.
Tor Serine-threonine Kinases
A serine threonine kinase that controls a wide range of growth-related cellular processes. The protein is referred to as the target of RAPAMYCIN due to the discovery that TACROLIMUS (commonly known as rapamycin) forms an inhibitory complex with TACROLIMUS BINDING PROTEIN 1A that blocks the action of its enzymatic activity.
Transketolase
An enzyme of the transferase class that catalyzes the conversion of sedoheptulose 7-phosphate and D-glyceraldehyde 3-phosphate to D-ribose 5-phosphate and D-xylulose 5-phosphate in the PENTOSE PHOSPHATE PATHWAY. (Dorland, 27th ed) EC 2.2.1.1.
