Filter by:This phase II trial studies how well tacrolimus and mycophenolate mofetil works in preventing graft-versus-host disease in patients who have undergone total-body irradiation (TBI) with or without fludarabine phosphate followed by donor peripheral blood stem cell transplant for hematologic cancer. Giving low doses of chemotherapy, such as fludarabine phosphate, and TBI 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). Sometimes the transplanted cells from a donor can also make an immune response against the body's normal cells. Giving tacrolimus and mycophenolate mofetil after the transplant may stop this from happening.
This phase I/II trial is studying the side effects of biological therapy and to see how well it works in treating patients with advanced myelodysplastic syndrome, chronic myeloid leukemia, acute myeloid leukemia, or acute lymphoblastic leukemia. Biological therapies, including immunotherapy, can potentially be used to stimulate the immune system and stop cancer cells from growing. Immunotherapy given to patients who have undergone donor stem cell transplantation may be a way to eradicate remaining cancer cells
This study will evaluate the effectiveness of the drug daclizumab for treating patients with chronic immune thrombocytopenia (ITP), a disease in which the immune system destroys platelets (blood cells involved in the clotting process). Patients with ITP have abnormal bruising and bleeding; severe disease can be life-threatening. For many patients, standard drug treatments are not effective, and many of the drugs used may have significant side effects with long-term use. Daclizumab is a genetically engineered antibody that suppresses the immune system and has been used primarily to prevent rejection in patients who have had organ transplants. Daclizumab has fewer side effects than other immune suppressant drugs. Patients with ITP 18 years of age or older who have platelet counts less than 30,000/microliter and have not responded to prednisone treatment may be eligible for this study. Candidates will be screened with a medical history, physical examination, and blood tests. Participants will have a 15-minute infusion of daclizumab every 2 weeks for five doses. They will be seen by a physician at least once every 2 weeks while receiving the drug and then at weeks 12, 20, and 32 of the study. Blood will be drawn at the 4- and 8-week visits during treatment for diagnostic tests, and at each follow-up visit after treatment to assess the response to therapy. Patients who respond well to treatment will have their pre-study immunosuppressive medicines tapered gradually one at a time starting with the 1-month follow-up visit. If their platelet count falls to pre-treatment levels at any time during the tapering, the dose reduction will stop and pre-study medications will be re-started, if necessary.
Phase II trial to study the effectiveness of tipifarnib in treating patients who have myelofibrosis with myeloid metaplasia. Tipifarnib may stop the growth of tumor cells by blocking the enzymes necessary for tumor cell growth.
Primary Objective: To assess the safety of bivalirudin as an alternative anticoagulant therapy for patients with new or previous heparin-induced thrombocytopenia (HIT) / heparin-induced thrombocytopenia and thrombosis syndrome (HITTS) undergoing percutaneous coronary intervention (PCI). This will be measured by the composite incidence of major bleeding events during administration or within 48 hours after stopping bivalirudin (or at hospital discharge, whichever occurs first). The components of the composite endpoint are: a) intracranial bleeding; b) retroperitoneal bleeding; c) bleeding that results in hemodynamic compromise; d) bleeding that requires transfusion of three or more units of whole blood or packed red cells; and e) a decrease in hemoglobin of greater than or equal to g/dL or in hematocrit of greater than or equal to 9%. Secondary Objectives: Each component of the primary composite endpoint. To evaluate the level of anticoagulation achieved with bivalirudin. The goal is to achieve an activated clotting time (ACT) between 300 and 350 sec during PCI and 4-hour bivalirudin infusion. To evaluate bivalirudin's effects on platelet counts.
Intensive chemotherapy is associated with significant thrombocytopenia, often requiring platelet transfusion to maintain platelet counts. This investigational drug has been demonstrated to increase platelet counts. This study will test the safety and efficacy of the investigational drug in the prevention of thrombocytopenia in patients with recurrent or refractory intermediate-grade or high-grade non-Burkitt's, non-Hodgkin's lymphoma (NHL), or Hodgkin's disease receiving DHAP (Dexamethasone, high-dose Cytarabine, and Cisplatin) chemotherapy.
The purpose of this study is to evaluate the safe and effective dose of Argatroban for prophylaxis and/or treatment of thrombosis in pediatric patients with current or previous diagnosis of heparin-induced thrombocytopenia (HIT) and thrombosis syndrome (HITTS), or who in the opinion of the investigator require alternative anticoagulation due to an underlying condition.
Phase II trial to study the effectiveness of imatinib mesylate in treating patients who have myelofibrosis. Imatinib mesylate may stop the growth of myelofibrosis by blocking certain enzymes necessary for cell growth.
Intensive chemotherapy is associated with significant thrombocytopenia, often requiring platelet transfusion to maintain platelet counts. This investigational drug has demonstrated the ability to increase platelet counts. This study will test the safety and efficacy of an investigational drug in the prevention of thrombocytopenia in patients with high-risk sarcoma receiving AI (Adriamycin/Ifosfamide) chemotherapy.
Intensive chemotherapy is associated with significant thrombocytopenia, often requiring platelet transfusion to maintain platelet counts. This investigational drug has demonstrated the ability to increase platelet counts. This study will test the safety and efficacy of this investigational drug in the prevention of thrombocytopenia in patients with solid tumors, lymphomas or multiple myeloma who are receiving myelosuppressive treatment regimens requiring platelet transfusion support.
