Filter by:The purpose of this study is to determine if we can prevent Epstein Barr Virus lymphomas by the monthly administration of an (antibody) protein against B lymphocytes called Rituximab. Although this medicine has been approved by the Food and Drug Administration to treat patients with other types of lymphomas, and has been used to treat a small number of patients with EBV lymphomas and other types of B-cell leukemias, it has not been approved to try and prevent EBV-lymphomas. Use of Rituximab to try to prevent EBV-lymphomas is therefore experimental.
Hsp90 is a chemical in the body that is involved in promotion of cancer. SNX-5422 is an experimental drug that blocks Hsp90. It is being evaluated for safety and efficacy in patients with cancer.
RATIONALE: Classical chemotherapy does not cure advanced chronic lymphocytic leukemia (CLL) despite new drugs. Rituximab is a monoclonal antibody directed against CD20 surface antigen on B lymphocytes and leads to apoptosis of CD20 positive B lymphocytes. The highest response rate yet published in the treatment of first-line CLL has been obtained by the association of fludarabine, cyclophosphamide and rituximab (FCR). Now, the question is whether this response can be improved, as some trials showed that eradication of minimal residual disease (MRD) in CLL is associated with a longer treatment-free and overall survival. Maintenance therapy using rituximab has been recently approved as a means of prolonging remission in patients with indolent non Hodgkin's lymphoma. Maintenance therapy with rituximab could be of interest in treatment of MRD in CLL and prolonging remission and survival times. PURPOSE: The overall purpose of the study is to determine the value of immunotherapy maintenance with single agent rituximab in comparison with no further treatment (observation ) for previously untreated chronic lymphocytic leukaemia in elderly (>65 years) patients who respond to induction immunochemotherapy with FCR.
Primary objective: To determine the dose limiting toxicity (DLT) and maximum tolerated dose (MTD) of TCN-PM (Triciribine) when administered as an approximately one-hour intravenous infusion on a weekly schedule on days 1, 8 and 15 in a 28 day cycle in patients with advanced hematologic malignancies; To determine the pharmacokinetics (PK) of Triciribine following study drug administration. Secondary objective: To observe the anti-tumor effects of Triciribine, if any occur
RATIONALE: Giving chemotherapy, such as clofarabine and melphalan, before a donor 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 cyclosporine and mycophenolate mofetil after the transplant may stop this from happening. PURPOSE: This phase I trial is studying the side effects and best dose of clofarabine when given together with high-dose melphalan followed by a donor stem cell transplant in treating patients with acute myeloid leukemia, acute lymphocytic leukemia, or myelodysplastic syndromes.
Modern frontline therapy for patients with hematologic malignancies is based on intensive administration of multiple drugs. In patients with relapsed disease, response to the same drugs is generally poor, and dosages cannot be further increased without unacceptable toxicities. For most patients, particularly those who relapse while still receiving frontline therapy, the only therapeutic option is hematopoietic stem cell transplantation (SCT). For those who relapse after transplant, or who are not eligible for transplant because of persistent disease, there is no proven curative therapy. There is mounting evidence that NK cells have powerful anti-leukemia activity. In patients undergoing allogeneic SCT, several studies have demonstrated NK-mediated anti-leukemic activity. NK cell infusions in patients with primary refractory or multiple-relapsed leukemia have been shown to be well tolerated and void of graft-versus-host disease (GVHD) effects. Myeloid leukemias are particularly sensitive to NK cells cytotoxicity, while B-lineage acute lymphoblastic leukemia (ALL) cells are often NK-resistant. We have developed a novel method to expand NK cells and enhance their cytotoxicity. Expanded and activated donor NK cells have shown powerful anti-leukemic activity against acute myeloid leukemia (AML) cells and T-lineage ALL cells in vitro and in animal models of leukemia. The present study represents the translation of these laboratory findings into clinical application.We propose to determine the safety of infusing expanded NK cells in pediatric patients who have chemotherapy refractory or relapse hematologic malignancies including AML, T-lineage ALL, T-cell lymphoblastic lymphoma (T-LL), chronic myelogenous leukemia (CML), juvenile myelomonocytic leukemia (JMML),myelodysplastic syndrome (MDS), Ewing sarcoma family of tumors (ESFT) and rhabdomyosarcoma (RMS). The NK cells used for this study will be obtained from the patient's family member who will be a partial match to the patient's immune type (HLA type).
To evaluate the effectiveness and safety of forodesine in CLL patients
This is a 2-phase study during which patients with select myeloid leukemias or advanced myelodysplastic syndrome (MDS), who have failed, refused or are not eligible for standard treatment, will receive investigational study drug ARRY-520. The study has 3 parts. The first phase of the study, Phase 1, has 2 parts. In the first part of Phase 1, patients with select myeloid leukemias or advanced MDS will receive increasing doses of study drug on different schedules in order to achieve the highest dose possible that will not cause unacceptable side effects. Approximately 30 patients (per schedule) from the US will be enrolled in Part 1 (Completed). In the second part of Phase 1, patients with advanced MDS will receive the best dose of study drug and schedule determined from the first part of the study. Approximately 10 patients from the US will be enrolled in Part 2 (Completed). In the third part of the study, Phase 2, patients with acute myeloid leukemia (AML) or advanced MDS will receive the best dose of study drug and schedule determined from the first part of the study and will be followed to see what side effects the study drug causes and to see what effectiveness it has, if any, in treating the cancer. Approximately 40 patients from the US will be enrolled in Part 3 (Withdrawn).
RATIONALE: Monoclonal antibodies, such as alemtuzumab, can block cancer growth in different ways. Some block the ability of cancer cells to grow and spread. Others find cancer cells and help kill them or carry cancer-killing substances to them. PURPOSE: This phase I/II trial is studying the side effects and best dose of alemtuzumab in treating patients with B-cell chronic lymphocytic leukemia.
The purpose of this study is to investigate whether the administration of Voraxaze reduces exposure to leucovorin and its active metabolite to below the level achieved in patients who have not received Voraxaze.
