Active clinical trials for "Leukemia"

RATIONALE: Drugs used in chemotherapy, such as everolimus, work in different ways to stop cancer cells from dividing so they stop growing or die. Imatinib mesylate may stop the growth of cancer cells by blocking the enzymes necessary for their growth. Combining everolimus with imatinib mesylate may be effective in killing cancer cells that have become resistant to imatinib mesylate. PURPOSE: This phase I/II trial is studying the side effects and best dose of everolimus when given together with imatinib mesylate and to see how well they work in treating patients with chronic phase chronic myelogenous leukemia who are not in complete cytogenetic remission after previous imatinib mesylate.

This phase I trial is studying the side effects and best dose of rebeccamycin analog in treating patients with relapsed or refractory acute myeloid leukemia, myelodysplastic syndrome, acute lymphoblastic leukemia, or chronic myelogenous leukemia in blast phase. Drugs used in chemotherapy, such as rebeccamycin analog, work in different ways to stop cancer cells from dividing so they stop growing or die

The goals and objectives of this project are to evaluate the antileukemic activity of the investigational agent clofarabine in patients with acute myelogenous leukemia (AML), acute lymphocytic leukemia (ALL), and chronic myelogenous leukemia (CML) in accelerated and blastic phases.

This randomized phase II trial studies how well fludarabine (fludarabine phosphate) and rituximab with or without lenalidomide or cyclophosphamide work in treating patients with symptomatic chronic lymphocytic leukemia. Drugs used in chemotherapy, such as fludarabine phosphate and cyclophosphamide, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Monoclonal antibodies, such as rituximab, may block cancer growth in different ways by targeting certain cells. Lenalidomide may stimulate the immune system in different ways and stop cancer cells from growing. Giving fludarabine phosphate and rituximab together with lenalidomide or cyclophosphamide may be an effective treatment for chronic lymphocytic leukemia.

RATIONALE: Giving chemotherapy, such as fludarabine and cyclophosphamide, and total-body irradiation before a donor umbilical cord blood transplant helps stop the patient's immune system from rejecting the donor's stem cells. The donated stem cells may replace the patient's immune cells and help destroy any remaining cancer cells (graft-versus-tumor effect). Giving an infusion of the donor's T-regulatory cells after the transplant may decrease this effect. Sometimes the transplanted cells from a donor can also make an immune response against the body's normal cells. However, the donor immune system may also react against the recipient's tissues (graft-versus-host disease). PURPOSE: This phase I trial is studying the side effects and best dose of donor T-regulatory cells after an umbilical cord blood transplant in treating patients with advanced hematologic cancer or other disorder.

This phase II trial is studying how well sunitinib works in treating patients with myelodysplastic syndromes or chronic myelomonocytic leukemia. Sunitinib may stop the growth of abnormal cells by blocking some of the enzymes needed for cell growth.

The purpose of this study is to reduce the side-effects from anti-leukemia therapy. The therapy in this study is based upon treatment information learned from prior clinical research programs as well as from laboratory research.

This extension II study allowed for further follow-up of the disease under treatment with imatinib mesylate and allow the participants to continue to receive imatinib mesylate.

The goal of this clinical research study is to see if imatinib mesylate (Gleevec, STI571) can improve CML in chronic phase. Objectives: Primary Objective: To increase the proportion of patients achieving a complete cytogenetic response in patients with Ph-positive early chronic phase CML using initial Gleevec therapy. Secondary Objective: To evaluate the duration of cytogenetic response, duration of hematologic response and survival.

RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. PURPOSE: Phase II trial to study the effectiveness of fludarabine in treating patients who have chronic lymphocytic leukemia that has not been previously treated.
