Active clinical trials for "Leukemia, Myelogenous, Chronic, BCR-ABL Positive"

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 bortezomib in treating patients who have chronic myelogenous leukemia in chronic or accelerated phase.

RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Combining chemotherapy with peripheral stem cell transplantation may allow the doctor to give higher doses of chemotherapy drugs and 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 a person's immune system recover from the side effects of chemotherapy. PURPOSE: Phase II trial to study the effectiveness of chemotherapy and filgrastim followed by peripheral stem cell transplantation in treating patients who have chronic myelogenous leukemia.

This is a phase I/II clinical trial on the use of total marrow irradiation (TMI) given concurrently with fludarabine, a chemotherapy drug commonly used to treat leukemia, as a myeloablative therapy for patients undergoing Allo-HSCT. TMI is a targeted technique to deliver radiation to the bone marrow while minimizing dose to other normal organs in the body. In phase I of the clinical study, the dose of radiation to the bone marrow will be incrementally increased to determine the highest tolerated TMI dose. In phase II, the effectiveness of the TMI-fludarabine conditioning regimen utilizing that dose of radiation will be studied. Acute and long-term toxicity data as well as quality of life data will also be studied. *Stopping criteria was met during the first dose level cohort in Phase l. The trial will not continue into Phase II as originally planned.

This phase II trial studies how well bosutinib works in treating patients with chronic myeloid leukemia in chronic phase after frontline tyrosine kinase inhibitor (TKI) failure. Bosutinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.

This pilot phase II trial studies how well a new reduced intensity conditioning regimen that includes haploidentical donor NK cells followed by the infusion of selectively T-cell depleted progenitor cell grafts work in treating younger patients with hematologic malignancies that have returned after or did not respond to treatment with a prior transplant. Giving chemotherapy and natural killer cells before a donor progenitor cell transplant may help stop the growth of cells in the bone marrow, including normal blood-forming cells (progenitor cells) and cancer cells. It may also stop the patient's immune system from rejecting the donor's cells. When the healthy progenitor cells from a related donor are infused into the patient they make 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 (called graft-versus-host disease). Removing specific T cells from the donor cells before the transplant may prevent this.

The purpose of this trial is to assess the effect of switching CML patients, who have been treated with imatinib ≥ 2 years and who have stable detectable molecular residual disease between 0.01-1.0% (IS), to the combination of Nilotinib and PegIFN, in terms of the proportion of patients who achieve confirmed MR4.0.

The GIMEMA CML Working Party promotes a multicentre, observational, prospective study of CML patients treated frontline with NIL. Patients will be followed for 5 years. This study will help the definition of guidelines for the treatment of CML patients in early CP.

This phase I trial studies the side effects and the best way to give dasatinib and cyclosporine in treating patients with chronic myelogenous leukemia (CML) refractory or intolerant to imatinib mesylate. Dasatinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Cyclosporine may help dasatinib work better by making cancer cells more sensitive to the drug. Giving dasatinib together with cyclosporine may be an effective treatment for CML.

This is a Phase I study designed to determine the MTD and assess the toxicity associated with clofarabine followed by fractionated cyclophosphamide in patients > 1 year of age or < 21 years of age with relapsed or refractory acute leukemias. There will be 25 to 35 patients enrolled. Cohorts of 3 to 6 patients each will receive escalated doses of clofarabine followed by fractionated cyclophosphamide until the MTD is reached. There will be no intra-patient dose escalation. Single-agent cyclophosphamide will be administered by 2-hour IVI on Day 0 of cycle 1. On Days 1, 2, and 3 and Days 8, 9, and 10 clofarabine will be administered by IVI 2 hours before each dose of cyclophosphamide (see the treatment schema below). A cycle is defined as 28 days.

This exploratory study will evaluate the change in molecular response in chronic myelogenous leukemia - chronic phase patients with a complete cytogenetic response and have a suboptimal molecular response to imatinib
