Filter by:OBJECTIVES To investigate: - the mechanism of Valproic Acid (VPA)-induced apoptosis in B-CLL - the ability of VPA in combination with standard chemotherapy or new antitumor agents to induce a synergistic antitumor effect in chronic lymphocytic leukemia (CLL) cells - the clinical efficacy of VPA in previously treated CLL patients. This will be an example of a translational research study where the results of our laboratory studies will be applied to a clinical trial in the CLL clinic at CancerCare Manitoba.
The goal of this clinical research study is to find the highest tolerable dose of AT9283 that can be given to patients who have ALL, AML, CML, high-risk myelodysplastic syndromes, or myelofibrosis with myeloid metaplasia. Researchers want to perform pharmacokinetic (PK) testing on blood to find out how quickly the study drug leaves the body and how the body breaks down the drug. The safety and effectiveness of this drug will also be studied.
In this study, the efficacy and safety of nilotinib 400 mg twice daily, will be compared with imatinib 400 mg twice daily in patients with a suboptimal response to imatinib for their Philadelphia chromosome-positive (Ph+) Chronic Myelogenous Leukemia in the chronic phase (CML-CP).
This is a pilot study designed to evaluate the safety and feasibility of performing umbilical cord blood transplants in adults with high-risk hematopoietic malignancies. A novel myeloablative preparative regimen will be used. One, up to a maximum of three cord blood units will be administered to facilitate engraftment.
Primary Objectives: 1. To determine the feasibility of delivering autologous dendritic cells (DCs) loaded with acute myelogenous leukemia (AML) lysate plus messenger RNA (mRNA) to AML patients following consolidation therapy. 2. To determine the toxicity of autologous DCs loaded with AML lysate plus mRNA. 3. To quantitate immune responses in patients who receive autologous DCs loaded with AML lysate plus mRNA. Secondary Objectives: 1. To evaluate minimal residual disease following DC therapy using the polymerase chain reaction assay for the Wilm's Tumor-1 gene. 2. To asses the disease-free and overall survival of AML patients who receive the autologous DCs loaded with AML lysate plus mRNA.
RATIONALE: Drugs used in chemotherapy, such as fludarabine, 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. Giving fludarabine together with rituximab may kill more cancer cells. Sometimes the cancer may not need treatment until it progresses. In this case, observation may be sufficient. It is not yet known whether giving fludarabine together with rituximab early is more effective than giving fludarabine and rituximab after observation in treating chronic lymphocytic leukemia. PURPOSE: This randomized phase III trial is studying fludarabine and rituximab to compare how well they work when given early or after observation in treating patients with previously untreated chronic lymphocytic leukemia.
This is a pilot study designed to evaluate the safety and feasibility of performing umbilical cord blood transplants in older adults or younger infirm patients with high-risk hematopoeitic malignancies. A novel reduced-intensity preparative regimen for umbilical cord blood transplantation will be used. One to a maximum of three cord blood units, depending on cell count, will be administered to facilitate engraftment. Ten patients will be enrolled with an expected accrual rate of 3-4 patients per year and with a goal of completing accrual within 2-3 years.
The primary objective of this study is to determine whether low-dose cytarabine in combination with arsenic trioxide is more effective than low-dose cytarabine alone in achieving complete remission in elderly patients (≥60 years of age) with acute myeloid leukemia.
1. The primary objectives of this study are: 1. To determine the tolerability of RTA 744 Injection in patients with leptomeningeal disease (LMD) secondary to any type of primary tumor. 2. In a selected group of 6-10 patients who will receive RTA 744 at or near the maximum tolerated dose (MTD), to characterize the multiple-dose pharmacokinetics of RTA 744 in plasma and CSF. 2. The secondary objectives of this study are: 1. To document any potential antitumor activity of RTA 744 in this patient population. 2. To correlate pharmacokinetic information with clinical (efficacy and safety) responses, as a possible help in selecting appropriate doses for later studies.
Primary Objectives: 1.1 Estimate rate of response and define acute toxicity to etanercept used in an up-front phase II window in newly diagnosed or relapsed JMML. 1.2 Determine if response to Tumor Necrosis Factor (TNF) blockade correlates with genetic basis of Juvenile Myelomonocytic Leukemia (JMML) [mutations in NF1, Ras, SHP2] or levels of TNFa. 1.3 Determine if TNF blockade by etanercept results in inhibition of free levels of TNFa and other cytokines by ELISA and bioassay and improves blood counts. 1.4 Estimate the two year event free survival and overall survival in JMML patients following etanercept and allogeneic hematopoietic stem cell transplantation.
