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

Blood and marrow stem cell transplant has improved the outcome for patients with high-risk hematologic malignancies. However, most patients do not have an appropriate HLA (immune type) matched sibling donor available and/or are unable to identify an acceptable unrelated HLA matched donor through the registries in a timely manner. Another option is haploidentical transplant using a partially matched family member donor. Although haploidentical transplant has proven curative in many patients, this procedure has been hindered by significant complications, primarily regimen-related toxicity including GVHD and infection due to delayed immune reconstitution. These can, in part, be due to certain white blood cells in the graft called T cells. GVHD happens when the donor T cells recognize the body tissues of the patient (the host) are different and attack these cells. Although too many T cells increase the possibility of GVHD, too few may cause the recipient's immune system to reconstitute slowly or the graft to fail to grow, leaving the patient at high-risk for significant infection. For these reasons, a primary focus for researchers is to engineer the graft to provide a T cell dose that will reduce the risk for GVHD, yet provide a sufficient number of cells to facilitate immune reconstitution and graft integrity. Building on prior institutional trials, this study will provide patients with a haploidentical graft engineered to specific T cell target values using the CliniMACS system. A reduced intensity, preparative regimen will be used in an effort to reduce regimen-related toxicity and mortality. Two groups of patients were enrolled on this study. One group included those with high-risk hematologic malignancies and the second group included participants with refractory hematologic malignancies or undergoing a second transplant. The primary aim of the study was to estimate the relapse rate in the one group of research participants with refractory hematologic malignancies or those undergoing second allogeneic transplant. Both groups will be followed and analyzed separately in regards to the secondary objectives. This study was closed to accrual on April 2006 as it met the specific safety stopping rules regarding occurrence of severe graft vs. host disease. Although this study is no longer open to accrual, the treated participants continue to be followed as directed by the protocol.

The goal of this clinical research study is to learn if giving PEG-Alpha Interferon (PEG-Intron) and Sargramostim (GM-CSF) to patients receiving treatment with high dose Gleevec (imatinib mesylate) is more effective in treating CML in chronic phase than therapy with imatinib mesylate alone.

The purpose of this study if to investigate the effect of lonafarnib (SCH66336) in combination with Gleevec in the treatment of CML.

The goal of this clinical research study is to find the highest safe dose of the drugs ZarnestraTM (R115777) and Gleevec (imatinib mesylate) that can be given in combination for the treatment of chronic myelogenous leukemia (CML) in chronic phase. The effect of this combination on the leukemia will also be studied.

To determine the safety and efficacy of decitabine in patients with Philadelphia chromosome-positive chronic myelogenous leukemia blastic phase that were previously treated with imatinib mesylate (STI 571) and became resistant/refractory or were found to be intolerant to the drug.

This phase I trial is studying the side effects and best dose of tanespimycin when given with cytarabine in treating patients with relapsed or refractory acute myeloid leukemia, acute lymphoblastic leukemia, chronic myelogenous leukemia, chronic myelomonocytic leukemia, or myelodysplastic syndromes. Drugs used in chemotherapy, such as tanespimycin and cytarabine, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Tanespimycin may also help cytarabine kill more cancer cells by making cancer cells more sensitive to the drug. Giving tanespimycin together with cytarabine may kill more cancer cells.

This clinical trial studies the side effects and best dose of giving fludarabine and total-body irradiation (TBI) together followed by a donor stem cell transplant and cyclosporine and mycophenolate mofetil in treating human immunodeficiency virus (HIV)-positive patients with or without cancer. Giving low doses of chemotherapy, such as fludarabine, and TBI before a donor bone marrow or peripheral blood stem cell transplant helps stop the growth of cancer or abnormal cells and 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). Sometimes the transplanted cells from a donor can also make an immune response against the body's normal cells. Giving cyclosporine (CSP) and mycophenolate mofetil (MMF) after the transplant may stop this from happening.

Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Colony-stimulating factors such as sargramostim 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.
