Filter by:The goal of this clinical research study is to learn if dasatinib can help to control myeloproliferative disorders. The safety and tolerability of dasatinib will also be studied.
RATIONALE: Drugs used in chemotherapy, such as treosulfan and fludarabine, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving treosulfan and fludarabine together with a donor bone marrow transplant or a peripheral stem cell transplant may be an effective treatment for acute myeloid leukemia, acute lymphoblastic leukemia, or myelodysplastic syndrome. PURPOSE: This phase II trial is studying giving treosulfan together with fludarabine to see how well it works in treating patients who are undergoing a donor stem cell transplant for acute myeloid leukemia, acute lymphoblastic leukemia, or myelodysplastic syndrome.
This study primarily determined the safety and tolerability of escalating doses of vosaroxin (SNS-595) in 2 dose schedules, and assessed the PK profile of vosaroxin and defined a recommended dose regimen for Phase 2 studies. Secondarily the study assessed potential biomarkers and antileukemic activity.
RATIONALE: Giving low doses of chemotherapy, such as fludarabine and busulfan, 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 system and help destroy any remaining cancer cells (graft-versus-tumor effect). Giving an infusion of the donor's T cells (donor lymphocyte infusion) after the transplant may help increase this effect. Sometimes the transplanted cells from a donor can also make an immune response against the body's normal cells. Giving cyclosporine and mycophenolate mofetil after the transplant may stop this from happening. PURPOSE: This phase I/II trial is studying the side effects of giving busulfan and fludarabine together with total-body irradiation and to see how well they work in treating patients who are undergoing a donor stem cell transplant for hematologic cancer.
The purpose of this study is to determine if peripheral blood cells collected following AMD3100 mobilization can be used safely for hematopoietic cell transplantation into HLA-matched recipients.
The primary objectives of the trial are to assess erythroid response to darbepoetin alfa, as determined by changes in hemoglobin and/or red blood cell (RBC) transfusion-dependence and to describe the safety profile of darbepoetin alfa in patients with MDS. The secondary objective is to assess bone marrow progenitor BFU-E growth before and after treatment with darbepoetin alfa.
This randomized phase I trial is studying the side effects and best dose of two different schedules of sorafenib in treating patients with refractory or relapsed acute leukemia, myelodysplastic syndromes, or blastic phase chronic myelogenous leukemia. Sorafenib 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.
This study will evaluate the safety and effectiveness of a genetically engineered antibody, alemtuzumab (Campath[R]) on patients with myelodysplastic syndrome. MDS is made up of malignant stem cell disorders that can mean low levels of red blood cells-that is, anemia-and low counts of white blood cells and platelets. Patients with MDS are at risk for infection, spontaneous bleeding, and possible progression to leukemia, a cancer of bone marrow. Although bone marrow can produce some blood cells, patients with MDS experience a decrease in production of blood cells. Alemtuzumab recognizes specific types of white cells called lymphocytes and destroys them. This study will examine not only the usefulness of the medication but also the side effects in patients with MDS. Patients ages 18 to 72 who have MDS that requires transfusions and who do not have HIV or a life expectancy of less than 6 months may be eligible for this study. Screening tests include a complete physical examination and medical history. There will be a collection of about 8 tablespoons of blood for analysis of blood counts as well as liver, kidney, and thyroid function; a pregnancy test; an electrocardiogram (EKG) to measure electrical activity of the heartbeat; an echocardiogram (ECHO), which uses sound waves to evaluate heart function; wearing of a Holter monitor for 24 hours while the electrical activity of the heart is recorded; and a bone marrow biopsy. Patients should not receive any vaccines when taking alemtuzumab or for at least 12 months after the last dose. In addition, patients should not take the herbal supplements Echinacea purpurea or Usnea 2 weeks before beginning the study and during it. For the study, all patients will receive a test dose of 1 mg of alemtuzumab infused into a vein during the course of 1 hour. If the dose is tolerated, the medication will be given at 10 mg doses into the vein for 10 days, as an infusion of 2 hours. Blood samples of 2 tablespoons will be taken daily, and vital signs will be measured daily. The ECHO and 24-hour Holter monitoring will be repeated after patients receive the last dose of the medication. Because suppression of the immune system results from a decrease in white cells that fight infections, patients will take medications to protect them against infections and to treat them if infections occur. If needed, patients will receive blood transfusions for their MDS. Side effects of alemtuzumab involve a temporarily significant lowering of the number of red blood cells, white cells, and platelets. Side effects of the infusion can be rigidity, or stiffness, and fever, as well as risks of infections resulting from the decrease of white blood cells. Blood counts and reactions to all procedures will be carefully monitored throughout the study. After patients receive the last dose of alemtuzumab, they will have follow-up by their referring doctor or at NIH. They must be able to return to NIH after 1 month, 3 months, 6 months, and annually for 5 years after the study. At follow-up visits, there will be blood tests to reevaluate blood counts and test for the presence of viruses. Blood tests will be done weekly for the first 3 months after patients have completed taking alemtuzumab, every other week until 6 months, and then annually for 5 years. There will also be a repeat ECHO at the 3-month visit, and a repeat bone marrow biopsy at the 5-month and 12-month follow-up visits, and as needed after that. This study may or may not have a direct benefit for participants. For some, the antibody may improve blood counts and decrease the need for transfusions. Knowledge gained in the study may help people in the future.
RATIONALE: Biological therapies, such as anti-thymocyte globulin and etanercept, may stimulate the immune system in different ways and stop cancer cells from growing. Giving anti-thymocyte globulin together with etanercept may kill more cancer cells. PURPOSE: This phase II trial is studying how well giving anti-thymocyte globulin together with etanercept works in treating patients with myelodysplastic syndromes.
The aim of this study is to compare the efficacy and tolerance of piperacillin-tazobactam versus piperacillin-tazobactam plus glycopeptide as initial empiric antibiotic treatment for fever in neutropenic patients. Study of consecutive cohorts(2). First the patients will be included in the monotherapy branch until completing the predicted number of cases. When this happens, the Coordinating Center will communicate it to the participant centers and from then the patients will be included in the combined therapy.
