Active clinical trials for "Leukemia"

To evaluate the effectiveness and safety of forodesine in CLL patients

RATIONALE: Giving chemotherapy before a donor bone marrow transplant or peripheral stem cell transplant helps stop the growth of cancer cells and helps stop the patient's immune system from rejecting the donor's stem cells. When certain stem cells from a donor 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 tacrolimus and mycophenolate mofetil after the transplant may stop this from happening. PURPOSE: This phase II trial is studying how well giving busulfan together with cyclophosphamide and antithymocyte globulin followed by donor stem cell transplant works in treating patients with hematologic cancer.

Phase I Study of Bevacizumab and Sorafenib Combined with Low Dose Cyclophosphamide in Patients with Refractory Solid Tumors and Leukemia. Patients with solid tumors (including central nervous tumors) that are recurrent or refractory to standard therapy, or for whom standard therapy is not available. Once a maximum tolerated dose (MTD) has been established in patients with recurrent or refractory solid tumors, the tolerability of this dose will be tested in patients with refractory or recurrent leukemia and an expanded cohort of patients with refractory or recurrent solid tumors.

The primary aim of this study is: • To analyze the efficacy (in order to evaluate the response) of a sequential treatment scheme of Bortezomib in combination with Fludarabine,Cytarabine and Idarubicin continued with Bortezomib monotherapy for patients with relapsed or refractory AML ≥18 years old. The safety aim of this study is: • To evaluate the safety and tolerance of the sequential treatment scheme proposed with Bortezomib combined with Fludarabine, Cytarabine and Idarubicin and in monotherapy, measured on clinical toxicities and laboratory incidences. The biological aim of this study is: • To evaluate the Minimal Residual Disease (MRD)impact that will be monitored by multiparametric flow cytometry carried out at different moments during the treatment.

The goal of this clinical research study is to find the highest safe dose of vorinostat that can be given in combination with idarubicin and ara-C for the treatment of AML and high-risk MDS. Once the highest safe dose is found, researchers will then try to learn if this combination treatment can help to control AML and high-risk MDS in newly diagnosed patients. The safety of this treatment combination will also be studied.

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.

The goal of this clinical research study is to learn if Vidaza (azacitidine) will help to control the disease in patients with AML, CMML, or MDS after an allogeneic (donor) stem cell transplant. The safety of this drug will also be studied.

The purpose of this research study is to determine if the GM-K562/leukemia cell vaccine can be safely given soon after allogeneic marrow or blood stem cell transplant. The GM-K562/leukemia cell vaccine is composed of a cultured cell line that has been genetically modified to secrete GM-CSF, a naturally occuring substance in the body that stimulates the immune system. The vaccine is a mixture of the GM-K562 cells (radiated to prevent them from growing in the participants body) with the participant's previously frozen and killed leukemia cells. By mixing the GM-K562 with the leukemia cells, we would like to study whether this vaccine combination will stimulate the participant's new immune system to recognize and fight against their MDS/AML cancer cells.

RATIONALE: Drugs used in chemotherapy, such as clofarabine, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Temsirolimus may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Giving clofarabine together with temsirolimus may kill more cancer cells. PURPOSE: This phase II trial is studying how well giving clofarabine together with temsirolimus works in treating older patients with relapsed or refractory acute myeloid leukemia.

This phase I trial studies the side effects and best dose of lenalidomide when given together with alvocidib in treating patients with relapsed or refractory B-cell chronic lymphocytic leukemia or small lymphocytic lymphoma. Lenalidomide may stop the growth of leukemia or lymphoma by blocking blood flow to the cancer. Alvocidib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Giving lenalidomide together with alvocidib may kill more cancer cells.
