PURPOSE: This phase II trial is studying the side effects and how well deferasirox works in treating patients with iron overload after donor stem cell transplant.
The purpose of this study is to compare the effects (good and bad) of the medication basiliximab in combination with cyclosporine with cyclosporine alone for the prevention of graft-versus-host disease. This research is being done because there is no completely safe and effective prevention for graft-versus-host disease. It is known that cyclosporine helps with GVHD but we would like to know if the addition of basiliximab will decrease the incidence and/or severity of GVHD after a transplant known as nonmyeloablative ("mini" transplant).
This will be a single arm Phase II study.
This study will test the combination of clofarabine, cytarabine, and thymoglobulin as a non-myeloablative conditioning regimen for patients with myelodysplastic syndromes or acute myeloid leukemia undergoing allogeneic stem cell transplant.
The purpose of this study is to determine if haplotype-mismatched HSCT is associated with an improvement in treatment-related mortality (TRM) rate at 6 months.
This phase I trial studies the side effects and best dose of iodine I 131monoclonal antibody BC8 when given together with fludarabine phosphate, cyclophosphamide, total-body irradiation, and donor bone marrow transplant, and to see how well they work in treating patients with acute myeloid leukemia or acute lymphoblastic leukemia that has spread to nearby or other places in the body (advanced), or high-risk myelodysplastic syndrome. Giving chemotherapy drugs, such as fludarabine phosphate and cyclophosphamide, and total-body irradiation before a donor bone marrow 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 cyclophosphamide together with mycophenolate mofetil and tacrolimus after the transplant may stop this from happening. Giving a radiolabeled monoclonal antibody together with donor stem cell transplant, fludarabine phosphate, cyclophosphamide, mycophenolate mofetil, and tacrolimus may be an effective treatment for advanced acute myeloid leukemia, acute lymphoblastic leukemia, or myelodysplastic syndromes.
The purpose of this study is to determine the maximum tolerated dose of alloreactive NK cells that can be transfused following stem cell transplant.
The objectives of this phase II trial are to test the efficacy and tolerance of Bevacizumab in MDS patients with excess of marrow blasts and to evaluate the impact of Bevacizumab on angiogenesis and erythropoiesis. To limit the myelotoxicity observed in the preliminary phase II study, Bevacizumab will be administrated at the initial dose of 5 mg/kg. The primary endpoint will be response: Complete Remission (CR), Partial Remission (PR) and hematological improvement (HI) according to IWG criteria (see appendix 3). The secondary endpoints will be survival, response duration, side effects, evaluation of angiogenesis (bone marrow microvessel density, VEGF plasma level, VEGF mRNA expression, HIF-1alpha expression). The design of this study consists of three study periods: pre-treatment (screening), treatment (loading and maintenance), and follow-up. All patients will participate in the study for at least 12 weeks of therapy, a 4-week follow-up visit, and long-term follow-up unless the criteria for planned or unplanned early discontinuation are met.
RATIONALE: Monoclonal antibodies, such as alemtuzumab, can find cancer cells and either kill them or deliver cancer-killing substances to them without harming normal cells. Giving chemotherapy drugs, such as busulfan and cyclophosphamide, before a donor stem cell transplant helps stop the growth of cancer 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 tacrolimus and methotrexate after the transplant may stop this from happening. PURPOSE: This phase I/II trial is studying the best dose of alemtuzumab when given together with busulfan and cyclophosphamide followed by a donor stem cell transplant and to see how well it works in treating patients with hematologic cancer.
This is a Phase II, single-arm, open-label, multinational, multicenter study of rATG in patients with low or intermediate-1 risk MDS who have either failed 1 prior treatment with growth factor(s), hypomethylating agents (5-azacitidine or decitabine), or the antiangiogenic agents lenalidomide or thalidomide, or who have never been treated for MDS (i.e., treatment-naïve patients).
