Summary

This phase I trial studies the side effects and best dose of iodine I 131 monoclonal antibody BC8 when given together with fludarabine phosphate and low-dose total-body irradiation followed by donor stem cell transplant and immunosuppression therapy in treating older patients with acute myeloid leukemia or high-risk myelodysplastic syndromes that cannot be controlled with treatment. Radiolabeled monoclonal antibodies, such as iodine I 131 monoclonal antibody BC8, can find cancer cells and carry cancer-killing substances to them. Giving chemotherapy, such as fludarabine phosphate, and total-body irradiation before a donor peripheral blood stem cell transplant helps stop the growth of cancer or abnormal cells. It may also stop the patient's immune system from rejecting the donor's stem cells. When the healthy stem cells from a donor are infused into the patient they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets. The donated stem cells may also replace the patient's immune cells and help destroy any remaining cancer cells. Sometimes the transplanted cells from a donor can also make an immune response against the body's normal cells. Giving radiolabeled monoclonal antibody therapy together with fludarabine phosphate and total-body irradiation before the transplant together with cyclosporine and mycophenolate mofetil after the transplant may stop this from happening.

Criteria

Inclusion Criteria:

• Patients with advanced AML defined as beyond first remission, primary refractory disease, or evolved from myelodysplastic or myeloproliferative syndromes; or patients with MDS expressed as refractory anemia with excess blasts (RAEB), refractory anemia with excess blasts in transformation (RAEBT [Note: classification removed under current World Health Organization [WHO] classification system]), refractory cytopenia with multilineage dysplasia (RCMD), RCMD with ringed sideroblasts (RCMD-RS), or chronic myelomonocytic leukemia (CMML)

• Patients in relapse must have documented cluster of differentiation (CD)45 expression by their myelodysplastic or leukemic cells to be studied and treated with 131I-labeled BC8 antibody; patients in remission do not require phenotyping and may have leukemia previously documented to be CD45 negative

• Patients should have a circulating blast count of less than 10,000/mm^3 (control with hydroxyurea or similar agent is allowed)

• Patients must undergo a 24-hour urine collection with documented creatinine clearance > 50 ml/min

• Bilirubin < 2 times the upper limit of normal

• Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) < 2 times the upper limit of normal

• Karnofsky score >= 70 or Eastern Cooperative Oncology Group (ECOG) =< 2

• Patients must have an expected survival of > 60 days and must be free of active infection

• Patients must have a human leukocyte antigen (HLA)-identical sibling donor or an HLA-matched unrelated donor who meets standard Seattle Cancer Care Alliance (SCCA) and/or National Marrow Donor Program (NMDP) criteria for peripheral blood stem cell (PBSC) donation; related donors should be matched by molecular methods at the intermediate resolution level at HLA-A, B, C, and DRB1 according to Fred Hutchinson Cancer Research Center (FHCRC) Standard Practice Guidelines and to the allele level at DQB1; unrelated donors should be identified using matching criteria that follows the FHCRC Standard Practice Guidelines limiting the study to eligible donors that are allele matched for HLA-A, B, C, DRB1, and DQB1 (grade 1), and accepting up to one allele mismatch as per standard practice grade 2.1 for HLA-A, B, or C; PBSC is the only permitted hematopoietic stem cell (HSC) source

• DONOR: Donors must meet HLA matching criteria as outlined above as well as standard Seattle Cancer Care Alliance (SCCA) and/or NMDP criteria for PBSC donation

Exclusion Criteria:

• Circulating antibody against mouse immunoglobulin (human anti-mouse antibody [HAMA])

• Prior radiation to maximally tolerated levels to any normal organ

• Patients may not have symptomatic coronary artery disease and may not be on cardiac medications for anti-arrhythmic or inotropic effects

• Inability to understand or give an informed consent

• Patients who are seropositive for human immunodeficiency virus (HIV)

• Perceived inability to tolerate diagnostic or therapeutic procedures, particularly treatment in radiation isolation

• Patients who have previously undergone marrow or PBSC transplantation
