Filter by:RATIONALE: Giving chemotherapy and total-body irradiation before a donor peripheral blood stem cell transplant helps stop the growth of cancer and abnormal cells and helps stop the patient's immune system from rejecting the donor's stem cells. When 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. Removing the T cells from the donor cells before transplant may stop this from happening. Giving an infusion of the donor's T cells (donor lymphocyte infusion) after the transplant may help destroy any remaining cancer cells (graft-versus-tumor effect). PURPOSE: This phase II trial is studying T-cell depletion in donor stem cell transplant followed by delayed T cell infusions in treating patients with hematologic cancer or other disease.
RATIONALE: Giving chemotherapy and total-body irradiation before a donor peripheral blood stem cell transplant helps stop the growth of cancer cells. It also stops the patient's immune system from rejecting the donor's stem cells. The donated stem cells may replace the patient's immune cells and help destroy any remaining cancer cells (graft-versus-tumor effect). Sometimes the transplanted cells from a donor can also make an immune response against the body's normal cells. Giving tacrolimus, sirolimus, antithymocyte globulin, and methotrexate before and after transplant may stop this from happening. PURPOSE: This phase II trial is studying how well sirolimus, tacrolimus, and antithymocyte globulin work in preventing graft-versus-host disease in patients undergoing a donor stem cell transplant for hematological cancer .
This phase I trial is studying the side effects and best dose of veliparib when given together with topotecan hydrochloride with or without carboplatin in treating patients with relapsed or refractory acute leukemia, high-risk myelodysplasia, or aggressive myeloproliferative disorders. Veliparib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as topotecan hydrochloride and carboplatin, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving veliparib together with topotecan hydrochloride and carboplatin may kill more cancer cells.
This phase II clinical trial is studying how well selumetinib works in treating patients with recurrent or refractory acute myeloid leukemia. Selumetinib may stop the growth of cancer by blocking some of the enzymes needed for cell growth
Gemcitabine and carboplatin are two standard chemotherapy drugs used to treat tumors of the urothelial tract. These drugs do not shrink tumors in all patients and when they do, it is generally for a limited amount of time. This has led scientists to look for different ways to treat cancer. New drugs have been developed to treat cancer that work differently than standard chemotherapy drugs. One new class of drugs are called 'angiogenesis-inhibitors'. These drugs attempt to decrease the blood supply to tumors. By doing so, this may limit the tumor's source of oxygen and nutrients and prevent the tumor from growing. Bevacizumab is an anti-angiogenic drug. In some other cancers such as colon cancer and lung cancer, combining bevacizumab with standard chemotherapy shrinks tumors in a greater proportion of patients and makes patients live longer than using standard chemotherapy alone. This has never been tested in urothelial cancer and we do not know if bevacizumab will have the same effects in this disease. The purpose of this study is to find out what effects, good and/or bad, the combination of gemcitabine, carboplatin, and bevacizumab has on you and your cancer.
Blood disorders such as leukemia or lymphoma or hemoglobinopathies can benefit from receiving an allogeneic (meaning that the cells are from a donor) stem cell transplant. Stem cells are created in the bone marrow. They grow into different types of blood cells that the body needs, including red blood cells, white blood cells, and platelets. In a transplant, the body's stem cells would be killed and then replaced by stem cells from the donor. Usually, patients are given very high doses of chemotherapy (drugs which kill cancer cells) prior to receiving a stem cell transplant. However, patients that are older, have received several prior treatments, or have other organ diseases are at a high risk of getting life-threatening treatment-related side effects from high doses of chemotherapy. Over the past several years, some doctors have begun to use lower doses of chemotherapy for preparing patients for a stem cell transplant. A condition that can occur after a stem cell transplant from a donor is Graft Versus Host Disease (GVHD). It is a rare but serious disorder that can strike persons whose immune system is suppressed and have received either a blood transfusion or a bone marrow transplant. Symptoms may include skin rash, intestinal problems similar to inflammation of the bowel and liver dysfunction. This research study uses a combination of lower-dose chemotherapy agents that is slightly different from those that have been used before. The medicines that will be used in this study are Fludarabine, Busulfan, both chemotherapy medicines, and Campath. Campath is a monoclonal antibody (a type of substance produced in the laboratory that binds to cancer cells). It helps the immune system see the cancer cell as something that needs to be destroyed. This research study will help us learn if using Fludarabine, Busulfan and Campath prior to an allogeneic stem cell transplant can provide treatment for blood disorders while decreasing the incidence of side effects.
Patients have a type of blood cell disorder that is very hard to cure. We are now suggesting a treatment that might help patients live longer without disease than other treatment plans would. This treatment is known as a stem cell transplant. We believe this may help patients as it allows us to give much stronger doses of drugs and radiation to kill the diseased cells than we could give without the transplant. We also think that the healthy cells may help fight any diseased cells left after the transplant. Stem Cells are special "mother" cells that are found in the bone marrow (the spongy tissue inside bones), although some are also found in the bloodstream (peripheral blood). As they grow, they become either white blood cells which fight infection, red blood cells which carry oxygen and remove waste products from the organs and tissues or platelets, which enable the blood to clot. For the transplant to take place, we will collect these stem cells from a "donor" (a person who agrees to donate these cells) and give them to recipient. Patients do not have a sibling that is a perfect match, so the stem cells will come from a donor who is the best match available. This person may be a close relative or an unrelated person whose stem cells best "matches" the patients, and who agrees to donate stem cells. Before the transplant, two very strong drugs plus total body irradiation will be given to the patient (pre-conditioning). This treatment will kill most of the blood-forming cells in the bone marrow. We will then give the patient the healthy stem cells. Once these healthy stem cells are in the bloodstream they will move to the bone marrow (graft) and begin producing blood cells that will eventually mature into healthy red blood cells, white blood cells and platelets. This research study will also use CAMPATH-1H as a pre-treatment. CAMPATH-1H is an antibody against certain types of blood cells. CAMPATH-1H is important because it stays active in the body for a long time after infusion, which means it may work longer at preventing GvHD symptoms. The stem cell transplant described above is considered to be "standard" treatment. We would like to collect additional blood as described below in order to evaluate how the immune system is recovering. We are asking permission to draw blood from the patient so that we can measure the number of certain blood cells called T regulatory cells. T regulatory cells are special immune cells that can control or regulate the body's immune response. We want to determine whether T regulatory cells are important participants in graft versus host disease (GVHD), infection and relapse. In GVHD, certain cells from the donated marrow or blood (the graft) attack the body of the transplant patient (the host). GVHD can affect many different parts of the body. The skin, eyes, stomach and intestines are affected most often. GVHD can range from mild to life-threatening. We do not know whether T regulatory cells can modify these conditions. We want to measure these T regulatory cells and learn if these cells do influence these conditions. If we learn that T regulatory cells do affect these conditions, then it may be possible to modify these cells for the benefit of transplant patients.
Currently, there is no accurate way of predicting the occurrence of Graft vs Host Disease (GvHD) or infection. The purpose of this study is to analyze blood with the ImmuKnow® Assay to see if doctors can detect which patients are at risk for GvHD and for getting an infection before they occur.
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.
RATIONALE: Giving chemotherapy and total-body irradiation before a donor peripheral stem cell transplant helps stop the growth of cancer or abnormal cells. It also helps 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. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells. Giving tacrolimus, methotrexate, cyclosporine, mycophenolate mofetil, and sirolimus before and after transplant may stop this from happening. PURPOSE: This phase II trial is studying how well donor peripheral stem cell transplant works in treating patients with advanced hematologic cancer or other disorders.
