Active clinical trials for "Leukemia"

The purpose of this study is to compare the effect of azacitidine (Vidaza) to conventional care regimens on overall survival in elderly AML patients.

RATIONALE: Bortezomib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as mitoxantrone, etoposide, and cytarabine, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving bortezomib together with combination chemotherapy may kill more cancer cells. PURPOSE: This phase I trial is studying the side effects and best dose of bortezomib when given together with mitoxantrone, etoposide, and cytarabine in treating patients with relapsed or refractory acute myeloid leukemia.

Ofatumumab is an IgG1κ fully human monoclonal antibody (mAb) that specifically recognizes an epitope on the human differentiation antigen CD20 molecule. In vitro and in vivo studies demonstrated that ofatumumab depletes CD20 positive (CD20+) B cells through complement-dependent cytotoxicity (CDC) and antibody-dependent cell-mediated cytotoxicity (ADCC), which results in the antitumour effect. This is an open-label study to evaluate safety, tolerability, efficacy and PK profile of ofatumumab monotherapy in chronic lymphocytic leukemia (CLL) patients. Ofatumumab will be administered intravenously at the first dose of 300mg followed by 7 weekly infusions of 2000mg, followed by 4 infusions of 2000mg at every 4 weeks. Primary objective of the study (Part A) is to evaluate tolerability, and the study (Part B) is to assess overall response rate in CLL population. 10 subjects will be enrolled into this study. Subjects will be followed for 48 weeks.

This phase II trial is studying how well giving clofarabine and cytarabine together with filgrastim works in treating patients with newly diagnosed acute myeloid leukemia (AML), advanced myelodysplastic syndrome (MDS), and/or advanced myeloproliferative neoplasm. Drugs used in chemotherapy, such as clofarabine and cytarabine, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving the drugs in different doses may kill more cancer cells. Colony stimulating factors, such as filgrastim, may increase the number of immune cells found in bone marrow or peripheral blood and may help the immune system recover from the side effects of chemotherapy.

The purpose of this research is to evaluate the safety and effectiveness of the drugs lenalidomide and ofatumumab in the treatment of chronic lymphocytic leukemia (CLL).

Objectives: Primary endpoints: To achieve low levels of Polymerase Chain Reaction (PCR) ratios of B-cell antigen receptor (Bcr-Abl)/Bcr (molecular CR) in a significant proportion of patients after 12 months of higher doses (800 mg daily) of Gleevec therapy To increase the proportion of patients achieving a complete cytogenetic response in patients with Ph-positive chronic phase CML using initial higher dose Gleevec therapy. Secondary endpoints: To evaluate the durations of PCR negativity, cytogenetic response, hematologic control, and survival. To analyze differences in response rates and in prognosis within different risk groups and patient characteristics

RATIONALE: Giving chemotherapy before a donor umbilical cord blood transplant (UCBT) helps stop the growth of cancer and abnormal cells and helps stop the patient's immune system from rejecting the donor's stem cells. When the stem cells from an unrelated donor, that do not exactly match the patient's blood, 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 antithymocyte globulin before transplant and cyclosporine and mycophenolate mofetil after transplant may stop this from happening. PURPOSE: This phase II trial is studying how well donor umbilical cord blood stem cell transplant works in treating patients with hematologic malignancies.

The purpose of this study is to determine the efficacy and safety of a fixed-dose, daily regimen of orally administered PCI-32765 combined with ofatumumab in subjects with relapsed/refractory CLL/SLL and related diseases

The risk of immunosuppression deters many patients from receiving fludarabine, while combination chemotherapy regimens are poorly tolerated by elderly or infirm chronic lymphocytic leukemia (CLL) patients. Previous studies by our group and others have shown that rituximab is safe and well tolerated when used as a single agent in patients with CLL. In addition, maintenance therapy with rituximab was well tolerated by CLL patients, with probable prolongation of progression-free survival (Hainsworth et al. 2003). Based on pre clinical and clinical studies indicating possible increased efficacy of ofatumumab in patients with CLL, we wish to develop an antibody-only regimen for older patients and patients who refuse fludarabine-based regimens.

The purpose of the study is to first determine if temozolomide plus vorinostat in combination can control relapsed or refractory acute myeloid leukemia (AML) and determine if this combination can be safely taken. The study will look at the side effects of the Temozolomide plus Vorinostat in combination and whether the treatment schedule is tolerated.
