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

The goal of this clinical research study is to find the highest safe doses of PTK 787 (vatalanib) and Gleevec (imatinib mesylate) that can be given to treat Chronic Myelogenous Leukemia-Blastic Phase (CML-BP), Refractory Acute Myelogenous Leukemia (AML), or Agnogenic Myeloid Metaplasia (AMM). Another goal is to see how effective this combination treatment is.

Drugs used in chemotherapy such as CCI-779 work in different ways to stop cancer cells from dividing so they stop growing or die. This phase II trial is studying how well CCI-779 works in treating patients with relapsed or refractory acute myeloid leukemia, acute lymphoblastic leukemia, myelodysplastic syndrome, or chronic myelogenous leukemia in blastic phase

RATIONALE: Colony-stimulating factors, such as sargramostim, may increase the number of immune cells found in bone marrow or peripheral blood and may bring about complete remission in patients who have chronic phase chronic myelogenous leukemia. PURPOSE: This phase II trial is studying sargramostim to see how well it works in treating patients with chronic phase chronic myelogenous leukemia that is not in complete cytogenetic remission after initial treatment.

This study will evaluate the safety and effectiveness of imatinib (Gleevec(Registered Trademark)) in patients with chronic myelomonocytic leukemia (CMML) and atypical chronic myelogenous leukemia (CML). These conditions cause uncontrolled growth of malignant (cancerous) cells in the bone marrow that prevents the bone marrow from functioning normally in producing blood cells. The cancer cells also can spill over into the blood and invade other organs of the body. Imatinib has been approved by the Food and Drug Administration for treating chronic myelogenous leukemia, which has characteristics similar to atypical CML and to CMML, and data from other research suggests this drug may be able to produce a remission in forms of leukemia other than CML. Patients over 18 years of age with atypical CML or CMML may be eligible for this study. Candidates are screened with a medical history and physical examination, blood tests, electrocardiogram, chest x-ray, and bone marrow aspiration and biopsy (removal of a small piece of bone marrow tissue through a needle inserted into the hip bone). Participants take imatinib capsules once a day for 2 years. If at any time during the study the patient's blood counts begin to rise, disease symptoms develop, or the disease has progressed, the dose of imatinib is increased each week until the disease progression is stopped. Any patient whose disease does not response to treatment after 6 weeks of increased dosing and 30 days at the maximum daily dose of 800 mg is taken off the study and referred for different treatment. Patients are seen by their referring physician every week for the first 4 weeks of the study, every other week for the next 8 weeks, and then monthly until the study is completed. At each visit, blood is drawn to monitor for drug side effects and response to therapy. In addition, patients come to the NIH Clinical Center every 3 months for a complete history and physical examination and for a bone marrow aspiration and biopsy every 6 months to assess the effect of treatment on bone marrow cells. Patients who leave the study before 2 years are followed with laboratory monitoring for 6 months after stopping imatinib; those who remain on the drug for the full 2 years are monitored for 1 year after stopping the drug.

RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Peripheral stem cell or bone marrow transplantation may be able to replace immune cells that were destroyed by chemotherapy used to kill tumor cells. Sometimes the transplanted cells can make an immune response against the body's normal tissues. Stem cells that have been treated in the laboratory with filgrastim may prevent this from happening. Combining chemotherapy with bone marrow or peripheral stem cell transplantation may allow the doctor to give higher doses of chemotherapy drugs and kill more cancer cells. It is not yet known which treatment is more effective for chronic myeloid leukemia. PURPOSE: Randomized phase III trial to compare the effectiveness of donor peripheral stem cell transplantation with donor bone marrow transplantation in treating patients with chronic myeloid leukemia.

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 peripheral stem cell transplantation plus filgrastim in treating patients who have acute or chronic myelogenous leukemia.

This clinical trial studies fludarabine phosphate, low-dose total-body irradiation, and peripheral blood stem cell transplant followed by donor lymphocyte infusion in treating older patients with chronic myeloid leukemia. Giving chemotherapy and total-body irradiation before a donor bone marrow transplant helps stop the growth of cancer cells. It may also stop the patient's immune system from rejecting the donor's stem cells. When the healthy 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 cyclosporine and mycophenolate mofetil after the transplant may stop this from happening. Once the donated stem cells begin working, the patient's immune system may see the remaining cancer cells as not belonging in the patient's body and destroy them (called graft-versus-tumor effect). Giving an infusion of the donor's white blood cells (donor lymphocyte infusion) may boost this effect.

This phase II trial is studying how well giving imatinib mesylate together with decitabine works in treating patients with accelerated or blast phase chronic myelogenous leukemia. Imatinib mesylate may stop the growth of cancer cells by blocking the enzymes necessary for cancer cell growth. Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Giving imatinib mesylate together with decitabine may kill more cancer cells

Phase I trial to study the effectiveness of PS-341 in treating patients who have refractory or relapsed acute myeloid leukemia, acute lymphoblastic leukemia, chronic myeloid leukemia in blast phase, or myelodysplastic syndrome. PS-341 may stop the growth of cancer cells by blocking the enzymes necessary for cancer cell growth

This phase II trial is studying imatinib mesylate to see how well it works in treating patients with chronic myelogenous leukemia. Imatinib mesylate may stop the growth of cancer cells by blocking the enzymes necessary for cancer cell growth
