简要总结
This phase II trial studies the side effects and best dose of iodine I 131 monoclonal antibody BC8 when given together with fludarabine phosphate, total-body irradiation, and donor stem cell transplant followed by cyclosporine and mycophenolate mofetil in treating patients with acute myeloid leukemia or myelodysplastic syndrome that has spread to other places in the body and usually cannot be cured or controlled with treatment. Giving chemotherapy drugs, 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 and helps stop the patient's immune system from rejecting the donor's stem cells. Also, radiolabeled monoclonal antibodies, such as iodine I 131 monoclonal antibody BC8, can find cancer cells and carry cancer-killing substances to them without harming normal 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. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells. Giving fludarabine phosphate and total-body irradiation before the transplant together with cyclosporine and mycophenolate mofetil after the transplant may stop this from happening. Giving a radiolabeled monoclonal antibody together with donor stem cell transplant, cyclosporine, and mycophenolate mofetil may be an effective treatment for advanced acute myeloid leukemia or myelodysplastic syndromes.
详细描述
PRIMARY OBJECTIVES:
I. To evaluate the maximum tolerated dose (MTD) and the transplant-related mortality (TRM) and toxicity of delivering 131I-BC8 (iodine I 131 monoclonal antibody BC8) (anti-cluster of differentiation [CD]45 antibody) at a starting dose of 22 Gy to the normal organ receiving the highest dose in combination with the non-myeloablative regimen of fludarabine (fludarabine phosphate) (FLU), 2 Gy total body irradiation (TBI), cyclosporine (CSP), mycophenolate mofetil (MMF), and human leukocyte antigen (HLA)-matched related or unrelated allogeneic hematopoietic stem cell transplant (HSCT) in patients 16 to 50 years old who have advanced acute myeloid leukemia (AML) or high risk myelodysplastic syndrome (MDS).
II. To estimate rates of donor chimerism resulting from this combined preparative regimen and to correlate level of donor chimerism with estimated radiation doses delivered to hematopoietic tissues via antibody.
III. To determine rates of disease relapse, graft vs. host disease, and 2-year disease-free survival in patients receiving 131I-BC8 antibody combined with FLU, 2 Gy TBI, CSP, MMF, and HLA-matched related or unrelated allogeneic HSCT.
OUTLINE: This is a dose-escalation study of iodine I 131 monoclonal antibody BC8.

入选标准

- •Patients not in remission must have CD45-expressing leukemic blasts or myelodysplastic cells; patients in remission do not require phenotyping and may have leukemia previously documented to be CD45 negative (because in remission patients, virtually all antibody binding is to non-malignant cells which make up >= 95% of nucleated cells in the marrow)
- •Patients should have a circulating blast count of less than 10,000/mm^3 (control with hydroxyurea or similar agent is allowed)

- •Patients must have an expected survival of > 60 days and must be free of active infection
- •Patients must have an 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) or other donor center 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 developmentally regulated RNA binding protein 1 (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

结局指标
主要结局
Number of Participants With Dose-limiting Toxicities (DLT) 100 Days After Transplant
时间窗: Up to 100 days post-transplant
The criteria of Grade III/IV regimen-related toxicity (Bearman) or dose-limiting toxicity (DLT) are as follows: Grade 1 Development of transient chemical abnormalities which are not of major clinical consequence and which reverse without requiring major medical interventions. In general, the intent of this toxicity scale is to observe transient target organ toxicity which is reversible. Grade 2 Development of chemical or laboratory abnormalities that are persistent and which may represent target organ damage that may not be readily reversed. It is anticipated that at this dose of the drug, the toxicity obtained would be manageable by clinical methods but may interfere with other therapies. Grade 3 Development of major clinical, chemical or laboratory abnormalities which represent maximum toxicities without being fatal. This grade of toxicity is designed to be the dose-limiting toxicity.
次要结局
- Number of Participants With 100% Donor Chimerism at Day 28 and Day 84(Day 28 and Day 80 after transplant)
- Two-year Disease-free Survival of Study Participants Who Completed the Study Regimen(2 years post transplant)
- Number of Participants With Transplant Related Mortality Within 100 Days After Transplant(Up to 100 days post-transplant)
- Participant Disease Response Within 4 Weeks After Transplant(4 weeks after transplant)
- Severity of Acute GVHD in Patients Who Completed the Study Treatment(100 days after transplant)
