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

This study is a means of providing transplantation to those patients who would be a stem cell transplant candidate who do not have an appropriate donor. The use of CD34 selected haploidentical donor with an umbilical cord unit may help provide earlier engraftment without the need for long term immunosuppression. This study tests a new method of bone marrow transplantation called combined haploidentical-cord blood transplantation. In this procedure, some of the blood forming cells (the stem cells) from a partially human leukocyte antigen (HLA) matched (haploidentical) related donor are collected from the blood, as well as cells from an umbilical cord are transplanted into the patient (the recipient) after administration of a "conditioning regimen". A conditioning regimen consists of chemotherapy and sometimes radiation to the entire body (total body irradiation, or TBI), which is meant to destroy the cancer cells and suppress the recipient's immune system to allow the transplanted cells to take (grow).

The primary purpose is to determine the ability of CD34+ selection and T cell depletion using the CliniMACS® device to prevent severe acute graft-versus-host disease (GVHD) in patients receiving a stem cell transplant from an alternative (unrelated and mismatched related) donor. The secondary objectives include evaluation of engraftment, immune recovery, and post-transplant infections. Patients requiring stem cell transplants for either malignant (cancerous) or non-malignant disease will be included in the study. The recipients will be grouped into one of two groups based on whether the donor is mismatched related (Cohort A) or unrelated (Cohort B). The patient will receive a conditioning regimen including chemotherapy drugs and/or total body irradiation based on the disease for which the transplant is performed.

Allogeneic hematopoietic transplant is curative for many patients with hematological neoplasms but conditions to provide optimal engraftment and anti-tumor efficacy with minimal toxicity are still under way. Clofarabine is a newly licensed agent with dramatic anti-leukemic activity. Its incorporation into a regimen for pre-transplant conditioning of acute leukemia and lymphoma patients is logical, exploiting both the anti-tumor activities it is recognized to have and the immunosuppressive activity seen with drugs in its class.

This study is designed to determine the safety, maximum tolerated dose,dose limiting toxicity of Terameprocol(EM-1421)and determine the pharmacokinetics (clearance from the blood)of Terameprocol(EM-1421)given as intravenous infusion three times a week in patients with leukemia.

This study is for patients with relapsed of disease after allogeneic bone marrow The donor's T cells are activated by exposure to 2 compounds or antibodies that bind (or stick to) two compounds on T cells called CD3 and CD28. When these antibodies stick to both CD3 and CD28 on the T cells, the T cells becomes stimulated (or "activated") and grows. CD3 and CD28 are the coating of a T cell and a T cell is part of the body's immune system. It is believed that when T cells are exposed to both of antibodies to CD3 and CD28 compounds at the same time, they become activated or "stimulated" and may be more effective in fighting infections or cancer cells. We call this therapy "activated donor lymphocyte infusions, or activated DLI (aDLI)". This current study is being performed to see whether it is safe and effective to administer higher doses of activated DLI or repeated doses of activated DLI. All patients will receive standard donor lymphocyte infusions first, and in addition will receive activated donor lymphocytes approximately 12 days later (DLI followed by aDLI). Depending on the response to this treatment, and depending on possible side effects (such as graft-vs-host disease as described below), patients in remission will then receive additional aDLI every 3 months for 4 more times, and patients not in remission within 6-12 weeks will receive higher dose aDLI. The timing of the higher dose aDLI will be determined by your physician depending on your disease and the rate of progression of your disease. The aDLI can be given as early as 6 weeks, or as late as 12 weeks (3 months).

This is a pilot study designed to evaluate the safety and feasibility of performing umbilical cord blood transplants in adults with high-risk hematopoietic malignancies. A novel myeloablative preparative regimen will be used. One, up to a maximum of three cord blood units will be administered to facilitate engraftment.

This is a phase II efficacy (indicates the capacity for beneficial change or therapeutic effect) and safety study of Dasatinib in patients with relapsed Chronic Myeloid Leukemia (CML) following a Stem Cell Transplant (SCT) and who are not benefiting from other treatment, such as imatinib therapy. A relapse is when an illness that has seemed to be getting better, or to have been cured, comes back or gets worse again. A total of 50 patients ≥18 years of age will be registered on the trial.

The purpose of this study is to determine the safest dose of the BCR-ABL inhibitor XL228, how often it should be taken, and how well people with leukemia tolerate XL228.

The purpose of this study is to compare the efficacy of dasatinib with that of high-dose (800-mg) imatinib in participants with chronic phase chronic myeloid leukemia who achieved only a suboptimal response after at least 3 months of monotherapy with 400-mg imatinib. The safety of these treatments will also be evaluated.

This phase II trial is studying how well sunitinib works in treating patients with idiopathic myelofibrosis. Sunitinib may stop the growth of abnormal cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the abnormal cells.
