Filter by:RATIONALE: Drugs used in chemotherapy, such as fludarabine and cyclophosphamide, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. 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. A peripheral stem cell transplant using stem cells from the patient or a donor may replace the patient's immune cells that were destroyed by chemotherapy. PURPOSE: This phase II trial is studying how well giving fludarabine together with alemtuzumab or cyclophosphamide followed by peripheral blood stem cell transplant or alemtuzumab works in treating patients with advanced or progressive chronic lymphocytic leukemia.
Cytokine-induced killer ( CIK ) cells have been shown by our lab to be cytolytic against both autologous and allogeneic acute myeloid leukemia ( AML ) cells. Large scale expansion of CIK cells has also been shown to be feasible in healthy allogeneic stem cell donors as well as in patients undergoing mobilization for autologous transplant. Donor lymphocyte infusion (DLI) has been shown to be active against some haematological malignancies including CML, AML, MDS,NHL and Hodgkin's disease. These donor lymphocytes can be further activated in vitro to become CIK cells. At least 2 other centers in the world have given allogeneic CIK cells for patients relapsing post allogeneic transplant for a variety of haematological malignancies. These early reports have demonstrated feasibility, absence of increased GVHD and possible efficacy in some cases. We are proposing a Phase I /II study on the feasibility / efficacy of immunotherapy with allogeneic CIK cells for patients who relapse after allogeneic marrow transplant for their haematological malignancies. These patients have to be either refractory to conventional donor lymphocyte infusion, or need a larger number of donor lymphocyte than could be provided by unmanipulated donor lymphocytes. Donor lymphocytes will be collected and cultured in GMP facilities to maturity, then infused into patients. This will be given in graded doses at 4 weekly intervals and continued on in the absence of GVHD till remission is achieved or disease progression occurs. Patients may receive various forms of chemotherapy appropriate to the clinical condition in each case before the allogeneic CIK infusion. Efficacy will be assessed by comparing the response to allogeneic CIK infusion vs that to due to conventional DLI, ie response to the two different treatment using DLI response as the comparator. We expect about 10 such cases to be done over the next 3 years. Significant statistics is unlikely to be generated but observation and description of the response can generate useful information for presence or not of the efficacy of such a treatment. If clinical efficacy and superiority over conventional DLI is demonstrated, then future allogeneic CIK may take the place of DLI in this group of poor prognosis patients who relapse after allogeneic transplant .
This phase I trial is studying the side effects and best dose of GTI-2040 in treating patients with relapsed, refractory, or high-risk acute leukemia, high-grade myelodysplastic syndromes, or refractory or blastic phase chronic myelogenous leukemia. Drugs used in chemotherapy, such as GTI-2040, work in different ways to stop the growth of cancer or abnormal cells, either by killing the cells or by stopping them from dividing.
RATIONALE: Drugs used in chemotherapy work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Imatinib mesylate may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. A peripheral stem cell transplant may be able to replace blood-forming cells that were destroyed by chemotherapy. When the healthy stem cells are infused into the patient they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets. Giving combination chemotherapy together with imatinib mesylate and peripheral stem cell transplant may be an effective treatment for acute lymphoblastic leukemia. Nevertheless, in the last few years GIMEMA has pubblished a paper in which 100% of Ph+ ALL patients reach HCR only with Imatinib, without any chemiotherapy. Thus, this treatment will be implemented in patients pertaining to this category.
We would like patients to be in a research study to determine the safety and effectiveness of special cells that may make their own immune system fight their cancer. To do this, we will put a special gene into cancer cells that have been taken from the patients body. This will be done in the laboratory. This gene will make the cells produce interleukin 2 (IL-2), which is a natural substance that may help their immune system kill cancer cells. Additionally, we will stimulate the cancer cells with normal embryonic fibroblasts (cells that develop into normal connective tissues in the body) so that they will make another natural protein called CD40 ligand (CD40L). Studies of cancers in animals suggest IL-2 performs better when mixed with CD40L. Some of these cells will then be put back into the patients body with the goal that they will act like a vaccine and stimulate their immune system to attack the CLL cells. Studies of cancers in animals and in cancer cells that are grown in laboratories suggest that combining substances like IL-2 and CD40L with cancer cells help the body recognize and kill cancer cells. We have already conducted a study similar to this in patients with CLL. In that study, the subjects received about three months of injections (shots). In those subjects we saw some changes in the subject's immune system that might indicate that the modified cells were helping their immune system fight the cancer. However, in most of the subjects this change in the immune system went away after the injections were stopped. In this study we want to see if we can make the change in the immune system last longer by giving more injections over a longer period of time. We hope that this might produce a better response directed at the CLL cells. We will also be looking at the effect on cells called cancer stem cells which grow into the CLL cells we see in the blood. Specifically, this study will allow subjects to receive the injections for up to one year.
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 II trial is studying the side effects and how well alemtuzumab works in treating patients with B-cell chronic lymphocytic leukemia in partial remission or complete remission.
The aim of this study is to determine the safety, tolerability and dose-limiting toxicities of KW-2478 and to determine the Maximum Tolerated Dose and recommended Phase II dose for patients with relapsed/refractory MM, CLL or B-cell NHL.
Primary Objectives: 1. Determine the maximum tolerated dose (MTD) and dose-limiting toxicity (DLT) of oxaliplatin in combination with fludarabine, Ara-C and rituximab in patients with Richter's transformation, prolymphocytic leukemia (PLL), or refractory/relapsed B-cell chronic lymphocytic leukemia (CLL). 2. Assess the complete response (CR) and partial response (PR) rate to combination therapy of oxaliplatin, fludarabine, Ara-C and rituximab in patients with Richter's transformation, PLL or refractory/relapsed B-cell CLL. 3. Determine the safety and toxicity profile of combination therapy of oxaliplatin, fludarabine, Ara-C and rituximab in patients with Richter's transformation, PLL or refractory/relapsed B-cell CLL. Secondary Objectives: 1. Determine the duration of response, failure-free survival, and overall survival. 2. Determine the incidence of infections (bacterial, fungal, and viral) in patients with Richter's transformation, prolymphocytic leukemia or refractory/relapsed B-cell CLL treated with rituximab, oxaliplatin, fludarabine and Ara-C; monitor immune parameters such as T cell counts and immunoglobulin levels; and monitor Epstein-Barr virus (EBV) status. 3. Characterize the pharmacodynamics of oxaliplatin in leukemia cells with respect to total adduct formation, cross-link formation and excision deoxyribonucleic acid (DNA) responses. Compare these parameters in cells from the same patient after treatment with oxaliplatin in combination with fludarabine and Ara-C.
The primary objective of this study is to see if enzastaurin affects the pGSK3 beta level in B-cell chronic lymphocytic leukemia (B-CLL) cells.
RATIONALE: Immunotoxins, such as anti-CD19 and anti-CD22, can find cancer cells that express CD19 and CD22 and kill them without harming normal cells. This may be an effective treatment for B-cell acute lymphoblastic leukemia. PURPOSE: This phase I trial is studying the side effects and best dose of anti-CD19 and anti-CD22 immunotoxins in treating patients with refractory or relapsed B-cell acute lymphoblastic leukemia.
