Filter by: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.
RATIONALE: Drugs used in chemotherapy, such as azacitidine and arsenic trioxide, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) may kill more cancer cells. PURPOSE: This phase II trial is studying how well giving azacitidine together with arsenic trioxide works in treating patients with myelodysplastic syndromes or chronic myelomonocytic leukemia.
The purpose of this trial is to determine if patients with hematologic diseases who have a HLA 6/6 matched related donor and are not eligible for a standard myeloablative stem cell transplant will have less severe graft versus host disease (GVHD), transplant related mortality, and less graft failure when treated with a non-myeloablative T-cell depleted stem cell transplant.
The purpose of this study is to determine if recipients of non-myeloablative ex-vivo T-cell depleted peripheral blood (PBSC) stem cell transplantation using a mismatched related donor will have less severe graft versus host disease (GVHD), transplant related mortality, and less graft failure compared to alternative haploidentical stem cell transplantation.
To study if decitabine can help to control Myelodysplastic Syndrome (MDS) in patients who have failed on therapy with azacytidine, the current standard of therapy.
The purpose of this study is to assess the benefit of lonafarnib (versus placebo) in patients with myelodysplastic syndrome (MDS) or chronic myelomonocytic leukemia (CMML). Benefit will be measured by achievement of platelet transfusion independence for at least 8-consecutive weeks, and without simultaneous worsening of hemoglobin and/or need for red blood cell (RBC) transfusion. Additional endpoints will be hematologic response (which includes complete remission, partial remission, hematologic improvement), number of RBC transfusions, bleeding events, infections and safety.
RATIONALE: Drugs used in chemotherapy, such as arsenic trioxide, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Cholecalciferol (vitamin D) may help cancer cells become normal cells. Giving arsenic trioxide together with cholecalciferol (vitamin D) may kill more cancer cells. PURPOSE: This phase II trial is studying how well giving arsenic trioxide together with cholecalciferol (vitamin D) works in treating patients with myelodysplastic syndromes.
A Notch signalling pathway inhibitor study in pediatric and adult patients with relapsed (worsening) or refractory (not responding to treatment) T-cell acute lymphoblastic leukemia/lymphoma (T-ALL).
Background: Patients with cancers of the blood and immune system often benefit from transplants of stem cells from a genetically well-matched sibling. However, severe problems may follow these transplants because of the high-dose chemotherapy and radiation that accompany the procedure. Also, donated immune cells sometimes attack healthy tissues in a reaction called graft-versus-host disease (GVHD), damaging organs such as the liver, intestines and skin. To reduce toxicity of high-dose preparative chemotherapy, this study performs allogeneic transplant after low doses of chemotherapy. In an attempt to improve anti-tumor effects without increasing GVHD, this study uses donor immune cells (T helper 2 (Th2) cells) grown in the laboratory; some patients will receive standard donor immune cells (not grown in laboratory). All patients will receive immune modulating drugs sirolimus and cyclosporine to prevent GVHD. Objective: To determine the safety, treatment effects and rate of GVHD in patients receiving transplants that use low-intensity chemotherapy, sirolimus plus cyclosporine, and transplant booster with either Th2 cells or standard immune cells. Eligibility: Patients 16 to 75 years of age with acute or chronic leukemia, non-Hodgkin's lymphoma, Hodgkin's disease, multiple myeloma, or myelodysplastic syndrome. Patients must have a suitable genetically matched sibling donor and adequate kidney, heart and lung function. Design: The protocol has three treatment groups: cohort 1, Th2 booster at two weeks post-transplant; cohort 2, standard T cell booster at two weeks post-transplant; cohort 3, multiple infusion of Th2 cells. Condition: Hematologic Neoplasms, Myeloproliferative Disorders Intervention: Biological; therapeutic allogeneic lymphocytes Drug: Sirolimus Study Type: Interventional Study Design: Primary Purpose: Treatment Phase: Phase II
Patients are being asked to participate in this study because they have a malignant blood disease such as Myelodysplastic Syndrome (MDS), Myeloproliferative Disorder (MPD), Acute Myelogenous Leukemia (AML) or Chronic Myelogenous Leukemia (CML). We feel that patients could benefit from an allogeneic (meaning the cells come from a donor other than themself) stem cell transplant. The donor would be a family member or an unrelated person that is felt to be a good match for the patient. Stem cells are cells that are made in the bone marrow (spongy material that fills the middle of the bones). As the stem cells grow, they change into different types of blood cells that they need. This includes red blood cells that carry oxygen around the body, white blood cells that help to fight infections, and platelets that help to prevent and stop bleeding. Usually, patients are given high doses of chemotherapy before a stem cell transplant. High doses of chemo destroy the bone marrow. Healthy stem cells from a donor are then given to replace the patient's unhealthy cells. However, because of complications with the patient's disease, they have a high risk of having life-threatening side effects. These include serious damage to organs such as the lung, liver, kidney and heart. There is also an increased risk of bacterial, fungal, and viral infections. The other major problem is when a donor's stem cells (also called the graft) find that the patient's cells ( the host cells) are not the same. The donor cells may try to destroy the host's cells. The cells at high risk are those of the skin, liver and intestines. This is called graft versus host disease (GVHD) and it can be fatal. Recently, doctors have been able to use less toxic chemotherapy treatments before patients receive their transplants. This less toxic treatment helps reduce some of the treatment related problems mentioned above. Patient's are being asked to be involved in a research study that uses this approach. One major risk of this low dose treatment is that the patient's body may reject the donor cells. This is called graft rejection. This study is designed to see if this low dose treatment is safe and effective. This treatment plan adds CAMPATH 1H (a special protein called an antibody) to a low dose chemotherapy regimen. After chemo, the patient will receive an allogeneic (cells come from a donor) stem cell transplant. Adding CAMPATH 1H to the transplant medicines may help in treating the disease. CAMPATH 1H may reduce life-threatening and treatment related side effects like GVHD. CAMPATH 1H stays active in the body for a long time which means it may work longer to prevent GVHD. CAMPATH 1H destroys lymphocytes, a type of white cells that help fight infection, and this helps prevent graft rejection. We want to see if the addition of CAMPATH 1H to the patient's pre-transplant low dose chemotherapy will decrease the side effects from an allogeneic stem cell transplant, while providing a curative treatment for patients with blood disorders.
