Filter by:RATIONALE: The Epstein-Barr virus can cause cancer and lymphoproliferative disorders. Valganciclovir is an antiviral drug that acts against the Epstein-Barr virus. Phenylbutyrate may make cells infected with Epstein-Barr virus more sensitive to valganciclovir. Giving phenylbutyrate together with valganciclovir may block the growth of Epstein-Barr virus-infected cells and kill more cancer cells. PURPOSE: This phase II trial is studying how well giving phenylbutyrate together with valganciclovir works in treating patients with relapsed or refractory Epstein-Barr virus-positive cancer.
RATIONALE: Listening to relaxing music during a bone marrow biopsy may be effective in reducing anxiety and pain. PURPOSE: This randomized clinical trial is studying how well music works in reducing anxiety and pain in adult patients undergoing bone marrow biopsy for hematologic cancers or other diseases.
Subjects are being asked to participate in this study because treatment of their disease requires them to receive a stem cell transplant. Stem cells or "mother" cells are the source of normal blood cells and lead to recovery of blood counts after bone marrow transplantation (BMT). Unfortunately, there is not a perfectly matched stem cell donor (like a sister or brother) and the subject's disease is considered rapidly progressive and does not permit enough time to identify another donor (like someone from a registry list that is not their relative). We have, however, identified a close relative of the subject's whose stem cells are not a perfect match, but can be used. However, with this type of donor, there is typically an increased risk of developing graft-versus-host disease (GVHD), a high rate of transplant failure, and a longer delay in the recovery of the immune system. GVHD is a serious and sometimes fatal side effect of stem cell transplant. GVHD occurs when the new donor cells (graft) recognizes that the body tissues of the patient (host) are different from those of the donor. When this happens, cells in the graft may attack the host organs, primarily the skin, liver, and intestines. The number of occurrences and harshness of severe GVHD depends on several factors, including the degree of genetic differences between the donor and recipient, the intensity of the pre-treatment conditioning regimen, the quantity of transplanted cells, and the recipient's age. In recipients of mismatched family member or matched unrelated donor stem cell transplants, there is a greater risk of GVHD so that 70-90% of recipients of unchanged marrow will develop severe GVHD which could include symptoms such as marked diarrhea, liver failure, or even death. In an effort to lower the occurrences and severity of graft-versus-host disease in patients and to lower the rate of transplant failure, we would like to specially treat the donor's blood cells to remove cells that are most likely to attack the patient's tissues. This will occur in combination with intense conditioning treatment that the patient will receive before the transplant.
This study will study the effects of the gene on the X chromosome that is associated with X-linked lymphoproliferative disease (XLPD)-an inherited disease affecting the immune system-on the function of the immune system. XLPD has been linked to an abnormality in a specific region of the X chromosome (one of 23 chromosome pairs that contain the genes that determine a person's hereditary makeup). The disease may develop after infection with the Epstein-Barr virus (EBV). EBV affects more than 95 percent of people in the United States. It usually does not cause any symptoms in children. In adolescents and adults, however, EBV can cause infectious mononucleosis and sometimes lymphoproliferative disease, such as XLPD. In these diseases lymph tissues, such as lymph nodes, may become enlarged and immune function (infection-fighting ability) impaired. This study will compare DNA from patients with XLPD with that of their unaffected relatives, of patients with other lymphoproliferative diseases and of normal controls. Patients of any age with XLPD, their unaffected relatives 18 years of age and older, and patients with other lymphoproliferative diseases may participate in this study. Blood samples will be collected from all participants to study the effects of the gene on the X chromosome that appears to be abnormal in XLPD on the function of the immune system. In a 6-week period, no more than 100 milliliters (about 7 tablespoons) of blood will be drawn from adults and no more than 1 ml (1/6 teaspoon) of blood per pound of body weight from children. Blood from patients with XLPD and their relatives will also be tested for HLA type (similar to blood type testing) and the ability of HLA-matched cells from patients and relatives to interact will be examined.
This phase I trial is studying the side effects and best dose of giving PDX101 together with 17-AAG in treating patients with metastatic or unresectable solid tumors or lymphoma. PDX101 may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the cancer. Drugs used in chemotherapy, such as 17-N-allylamino-17-demethoxygeldanamycin (17-AAG), work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving PXD101 together with 17-AAG may kill more cancer cells.
The purpose of this study is to compare Reduced Intensity Conditioning protocols containing either Thymoglobuline or Alemtuzumab in patients undergoing allogeneic transplant from voluntary unrelated donors.
This phase I trial is studying the side effects and best dose of PXD101 and bortezomib in treating patients with advanced solid tumors or lymphomas. PXD101 and bortezomib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. PXD101 may also cause cancer cells to look more like normal cells, and to grow and spread more slowly. Giving PXD101 together with bortezomib may kill more cancer cells.
This study will examine the use of alemtuzumab (Campath) in patients with T cell large granular lymphocytic leukemia (T-LGL). Patients with T-LGL often have reduced white blood cells, red blood cells and platelets, and increased numbers of abnormal cells called large granular lymphocytes (LGLs). Patients may have recurrent infections, anemia, or abnormal bleeding. Campath destroys specific parts of the abnormal LGLs, which interfere with the production of normal blood cells. This study will determine whether Campath can increase blood counts and reduce the number of abnormal LGLs in patients and will examine the side effects of the drug. Patients 18 to 85 years of age with T-LGL leukemia may be eligible for this study. Participants undergo the following procedures: Before starting Campath treatment - Medical history and physical examination, blood tests, electrocardiogram (ECG). - Echocardiogram (heart ultrasound) and 24-hour Holter monitoring (continuous ECG recording). - Bone marrow biopsy: About a tablespoon of bone marrow is withdrawn through a needle inserted into the hipbone. The procedure is done using local anesthetic. - Placement of central line, if needed: An intravenous line (tube) is placed into a major vein in the chest. It can stay in the body and be used for the entire treatment period. The line is used to give chemotherapy or other medications, including antibiotics and blood transfusions, and to collect blood samples. The line is usually placed under local anesthesia in the radiology department or the operating room. - Apheresis: A catheter (plastic tube) is placed in a vein in each arm. Blood is drawn from one vein and run through a cell-separating machine, where the white blood cells are collected and saved. The remaining blood is transfused back to the patients through the vein in the other arm. During Campath treatment - Campath therapy: After a small test dose, patients receive10 daily infusions of Campath, each of which lasts about 2 hours. The first few infusions are given at the NIH Clinical Center so that the patient can be monitored closely. - Induction therapy: Aerosolized pentamadine, valacyclovir and other medicines are given to protect against or treat various infections that commonly affect patients with suppressed immune systems. - Whole blood or platelet transfusions, if needed, and injections of growth factors, if needed. - Blood tests and check of vital signs (temperature, pulse, blood pressure) every day during treatment. Echocardiogram and 24-hour Holter monitor after the last dose of Campath. Follow-up evaluations after Campath treatment ends - Blood tests at home or at NIH (weekly for the first 3 months, then every other week until 6 months, then annually for 5 years - Echocardiogram at NIH (at 3 months only) - Bone marrow biopsy at NIH (at 6 and 12 months, then as clinically indicated) - One repeat apheresis collection for laboratory studies.
RATIONALE: AMG 706 may stop the growth of cancer cells by blocking blood flow to the cancer or by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as gemcitabine, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving AMG 706 together with gemcitabine may kill more cancer cells. PURPOSE: This phase I trial is studying the side effects and best dose of AMG 706 when given together with gemcitabine in treating patients with advanced solid tumors or lymphoma.
RATIONALE: Drugs used in chemotherapy, such as VNP40101M, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. PURPOSE: This phase I/II trial is studying the side effects and best dose of VNP40101M and to see how well it works in treating patients with Richter syndrome or refractory or relapsed chronic lymphocytic leukemia or other lymphoproliferative disorders.
