Active clinical trials for "Leukemia"

Primary Objective: 1. To study ex-vivo purging of autologous hematopoietic stem cells that will be used to support high-dose chemotherapy in patients with chronic myelogenous leukemia (CML). Major endpoints are neutrophil engraftment and survival. Secondary Objectives: To evaluate the toxicity of ex-vivo purged autologous cells when used to support high-dose chemotherapy. To evaluate the rate and duration of cytogenetic remissions achieved with this strategy. To determine the time to platelet recovery to 20,000/mm3. To determine the one-year survival rate.

The investigators' objective is to assess the efficacy of the combined treatment with enalapril and carvedilol in the prevention of left ventricular systolic dysfunction in patients with hematological malignancies submitted to intensive chemotherapy with potential cardiotoxicity. The hypothesis is that these drugs administered during chemotherapy may prevent left ventricular systolic dysfunction.

Many chemotherapy combinations may be used to treat patients with chronic lymphocytic leukemia (CLL). Although there are many options, a single, best option is not agreed upon by most cancer specialists. Bendamustine, a medicine recently approved for use in the United States, has been used in combination with rituximab in previous studies to treat patients whose CLL has returned after previous standard treatments. The purpose of this study is to determine whether bendamustine with rituximab is effective for the initial treatment of CLL for patients aged 65 and older.

RATIONALE: Drugs used in chemotherapy, such as fludarabine and pixantrone, 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 rituximab, 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. It is not yet known whether giving fludarabine together with rituximab is more effective with or without pixantrone in treating indolent non-Hodgkin lymphoma. PURPOSE: This randomized phase III trial is studying fludarabine and rituximab to compare how well they work with or without pixantrone in treating patients with relapsed or refractory indolent non-Hodgkin lymphoma.

The purpose of this study is to evaluate the safety of combined chemotherapy treatment (CLAG regimen) with Imatinib Mesylate (Gleevec) in patients with AML.

RATIONALE: Biological therapies, such as lenalidomide, may stimulate the immune system in different ways and stop cancer cells from growing. Monoclonal antibodies, such as rituximab, 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. It is not yet known whether lenalidomide is more effective with or without rituximab in treating chronic lymphocytic leukemia or small lymphocytic lymphoma. PURPOSE: This phase II trial is studying how well lenalidomide works when given with or without rituximab in treating patients with chronic lymphocytic leukemia or small lymphocytic lymphoma who have undergone autologous or syngeneic stem cell transplant.

This pilot study was designed in order to evaluate the safety and efficacy of an AmBisome loading dose regimen, in a weekly administration schedule, during the aplastic phase following induction or consolidation chemotherapy for acute leukaemia, and during the initial phase of allogeneic stem-cell transplant, which are both high risk periods as far as severe fungal infections development is concerned.

The goal of this clinical research study is to learn if treating umbilical cord blood with growth factors before a transplant can help to improve the body's ability to accept the cord blood transplants.

Hematopoietic stem cell transplantation (HSCT) is one of the best, and sometimes the only, option for the treatment of leukemia, particularly for patients with advanced-stage leukemia. However, relapse rate was still very high for advanced-stage leukemia. It was found in our previous study that infusion of granulocyte colony-stimulating factor (G-CSF)-primed peripheral blood progenitor cells (GPBPC) instead of non-primed lymphocytes exhibited a comparative or stronger graft-versus-leukemia (GVL) effect and comparative or less incidence of GVHD, rarely being complicated with pancytopenia. When GPBPC infusion was combined with the use of short-term immunosuppressant for GVHD prophylaxis, the incidence of fatal GVHD complicated with GPBPCI was further reduced. Our primary data showed the GPBPCI combined with the use of short-term immunosuppressant was feasible in patients with advanced leukemia to prevent relapse after HLA-mismatched HSCT. The study hypothesis: Prevention of relapse using granulocyte colony-stimulating factor-primed peripheral blood progenitor cells following hematopoietic stem cell transplantation in patients with advanced-stage acute leukemia can reduce relapse rate improve survival

This is a single-center open-label phase I clinical trial of delivering haploidentical natural killer (NK) cells matured ex vivo with ALT-801 followed by intravenous infusions of ALT-801 in patients with relapsed/refractory Acute Myeloid Leukemia (AML). The study will be conducted at M.D. Anderson Cancer Center (MDACC) and MDACC Children's Cancer Hospital in Houston, Texas.
