Radiolabeled Monoclonal Antibody, Cyclophosphamide, and Total Body Irradiation Followed By Donor Stem Cell Transplantation in Treating Patients With Advanced Acute Myeloid Leukemia
Radiolabeled BC8 (Anti-CD45) Antibody Combined With Cyclophosphamide and Total Body Irradiation Followed by HLA-matched Related or Unrelated Stem Cell Transplantation as Treatment for Advanced Acute Myeloid Leukemia and Myelodysplastic Syndrome
RATIONALE: Radiolabeled monoclonal antibodies can locate cancer cells and either kill them or deliver radioactive cancer-killing substances to them without harming normal cells. Drugs used in chemotherapy work in different ways to stop cancer cells from dividing so they stop growing or die. Radiation therapy uses high-energy x-rays to damage cancer cells. Donor stem cell transplantation may be able to replace immune cells that were destroyed by radiolabeled monoclonal antibody therapy, chemotherapy and radiation therapy.
PURPOSE: Phase II trial to study the effectiveness of combining radiolabeled monoclonal antibody with cyclophosphamide and total-body irradiation followed by donor stem cell transplantation in treating patients who have advanced acute myeloid leukemia.

Detailed Description
OBJECTIVES:
- Determine the efficacy, in terms of overall survival and disease-free survival, and toxicity of cyclophosphamide and total body irradiation in patients with acute myeloid leukemia beyond first remission receiving HLA-matched related or unrelated hematopoietic stem cell transplantation.
- Determine the maximum tolerated dose (MTD) of iodine I 131 monoclonal antibody BC8 (I131 MOAB BC8) in these patients.
- Estimate the MTD of radiation delivered by I 131 MOAB BC8 to marrow of these patients and assess the effects on growth of marrow stroma in vitro.
OUTLINE: This is radiation dose-escalation study. Patients are stratified according to available donor (related vs unrelated).
Patients receive a biodistribution dose of iodine I 131 monoclonal antibody BC8 (I131 MOAB BC8) IV, then a therapeutic dose of I131 MOAB BC8 IV 6-14 days later (day -12). Patients undergo total body irradiation twice daily on days -6 to -4. Patients receive cyclophosphamide IV on days -3 and -2. Bone marrow cells (or peripheral blood stem cells) are infused on day 0.
Patients with CNS leukemic involvement receive intrathecal methotrexate twice before the transplantation then every other week for 8 weeks beginning on day 32. These patients also receive cranial irradiation beginning on day 32.
Cohorts of 4 patients each receive escalating doses of iodine I 131 attached to a standard dose of monoclonal antibody BC8 until the maximum tolerated dose (MTD) is determined. The MTD is defined as the radiation dose preceding that at which 2 of up to 6 patients experience graft failure.
Patients are followed at 6, 9, and 12 months, every 6 months for 1 year, and then annually thereafter.
PROJECTED ACCRUAL: A total of 40 patients (20 per stratum) will be accrued for this study within 4 years.
