Filter by: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.
RATIONALE: Radiolabeled monoclonal antibodies can find cancer cells and carry cancer-killing substances to them without harming normal cells. This may be effective treatment for leukemia. PURPOSE: This phase I trial is studying the best dose of yttrium Y 90-labeled monoclonal antibody BU-12 in treating patients with advanced relapsed or refractory acute lymphoblastic leukemia or chronic lymphocytic leukemia.
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
The purpose of this research study is to see if the investigational drug EL625, when combined with traditional chemotherapy (rituximab, fludarabine, and cyclophosphamide), is effective in Persistent Chronic Lymphocytic Leukemia (CLL) and Small Lymphocytic Lymphoma (SLL)
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 goal of this clinical research study is to learn if Revlimid (lenalidomide) can help to reduce the level of leukemia in your body. The safety of this drug will also be studied.
The study is a two-arm, multi-center trial of Revlimid® and Rituximab, for the frontline treatment of patients with Chronic Lymphocytic Leukemia (CLL) designed and conducted by the CLL Research Consortium (CRC). The purpose of this study is to determine the response rate of the combination of Revlimid® and Rituximab in previously untreated CLL patients in two arms- those aged 65 years and above and those younger than 65. Secondary objectives will evaluate the safety of the combination of Revlimid® and Rituximab, response duration, improvement in hematologic parameters, and the significance of the tumor flare reaction. All patients will have assessment of known prognostic factors for CLL as well as novel prognostic factors will be evaluated for predicting response to treatment. Biologic corollary studies are designed to evaluate the mechanism of Revlimid® in CLL and the combination of Revlimid® and Rituximab.
Blood and lymph node cancers can begin in either the lymphatic tissues (as in the case of lymphoma) or in the bone marrow (as with leukemia and myeloma), and they all are involved with the uncontrolled growth of white blood cells. There are many subtypes of these cancers, e.g., chronic lymphocytic leukemia and non-Hodgkin lymphoma. Since there is evidence that these cancers cluster in families, this study aims to understand how genetics and environmental exposures contribute to the development of these cancers.
RATIONALE: Aldesleukin may stimulate natural killer cells to kill cancer cells. Treating natural killer cells with aldesleukin in the laboratory may help the natural killer cells kill more cancer cells when they are put back in the body. Giving monoclonal antibodies, such as rituximab, and chemotherapy drugs, such as fludarabine and cyclophosphamide, before a donor natural killer cell infusion helps stop the growth of cancer cells. It also helps stop the patient's immune system from rejecting the donor's stem cells. PURPOSE: This phase I/II trial is studying how well giving rituximab and chemotherapy followed by a donor natural killer cell infusion that has been treated in the laboratory with aldesleukin followed by aldesleukin works in treating patients with non-Hodgkin lymphoma or chronic lymphocytic leukemia.
