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

This is a 2 part study. The goal of the first part of this clinical research study is to find the highest tolerable dose of azacitidine that can be given with a TKI that you are already taking (such as Gleevec, Sprycel, or Tasigna). The safety of this drug will also be studied. The goal of the second part is to see if this combination may improve your response to the TKI you are already taking. Azacitidine is designed to change genes that are thought to cause leukemia. By changing these genes, the drug may help to stop them from causing the disease to grow.

This phase II trial studies how well giving treosulfan together with fludarabine phosphate and total-body irradiation (TBI) works in treating patients with hematological cancer who are undergoing umbilical cord blood transplant (UCBT). Giving chemotherapy, such as treosulfan and fludarabine phosphate, and TBI before a donor UCBT helps stop the growth of cancer cells and helps stop the patient's immune system from rejecting the donor's stem cells. When the stem cells from a related or unrelated donor, that do not exactly match the patient's blood, 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 also make an immune response against the body's normal cells. Giving cyclosporine (CsA) and mycophenolate mofetil (MMF) after the transplant may stop this from happening.

This study consists of two phases: the first portion of the study is a Phase 1 dose escalation study to determine the maximum tolerated dose and the dose limiting toxicities of SB1518 when given as a single agent orally once daily in subjects with advanced myeloid malignancies; the second portion of the study is a Phase 2 study to define the efficacy and safety profile of single-agent SB1518 at the recommended dose in subjects with chronic idiopathic myelofibrosis (CIMF).

Natural killer (NK) cells are white blood cells that have a limited ability to kill cancer cells. This ability might be enhanced if they are given 24 hours after an injection of the drug bortezomib. This study will determine the following: What dose of NK cells can be given safely to subjects with metastatic solid tumors or leukemia. The effectiveness and side effects of NK cell therapy How the body handles NK cells. People between 18 and 70 years of age who have a solid tumor or leukemia, and for whom standard treatments are not effective, may be eligible for this study. Participants undergo the following procedures: Apheresis to collect NK cells. For this procedure, a catheter (plastic tube) is placed in a vein in the subject s arm. Blood flows from the vein into a cell separator machine, which separates the white cells from the other blood components. The white cells are extracted and the rest of the blood is returned to the body through a second tube placed in a vein in the other arm. Chemotherapy with the drug pentostatin to suppress the immune system and prevent it from attacking the NK cells that will be infused. Chemotherapy with bortezomib to increase NK cell function. Infusion of the NK cells. In this dose-escalating study, successive groups of patients entering the study receive increasingly higher numbers of cells to determine the highest safe dose level. Up to ten dose levels may be studied. Interleukin-2 drug therapy to maintain NK cell activity. Evaluations during therapy including: Clinical assessment, history and review of medications Blood draws for routine and research tests. Pharmacokinetics study after the NK infusion to see how the body handles the cells. For this test, the number of NK cells in the blood are measured over time. This requires drawing about 1 teaspoon of blood at 15 minutes, 30 minutes, 1, 2, 4, 8, 12, and 24 hours after the infusion (day 1); then every 24 hours on days 2 through 7, then once on days 10, 14, and 21. Bone marrow biopsy (subjects with leukemia only). Chest x-ray. CT scan, bone scan and PET scan, if indicated, for disease evaluation. Subjects who respond well after one treatment cycle may be eligible to continue NK cell therapy.

This phase I/II trial is studying the side effects and best way to give nilotinib when given alone or sequentially after imatinib mesylate after donor stem cell transplant in treating patients with acute lymphoblastic leukemia or chronic myelogenous leukemia. Nilotinib and imatinib mesylate may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.

The purpose of this study is to determine the maximum tolerated dose (MTD) of TAK-901 in subjects with advanced hematological malignancies, and to further assess the safety and tolerability of TAK-901 at or below the MTD in an expanded cohort of subjects in order to select a dose for future studies.

There is no available data on the clinical benefit of dose escalation for patients with suboptimal response to imatinib, and patients may still improve their response with continuation of therapy at the standard dose as shown in the IRIS trial after 5 years of follow-up. However, there is no data yet regarding the potential benefit of using nilotinib in the group of patients with suboptimal response. In this study, the efficacy of nilotinib 400mg BID will be compared to imatinib 600mg QD.

Patients not previously exposed to imatinib and with resistant or refractory Ph+ ALL, lymphoid blast crisis chronic myelogenous leukaemia (LBC CML) or with de novo Ph+ ALL and aged over 55y were eligible in the study. The DIV regimen consisted in one IV injection of vincristine 2 mg combined with 2 days of dexamethasone 40 mg PO repeated weekly for 4 weeks as induction and then monthly for 4 months as consolidation. Imatinib was administered at 800 mg per day during the induction period and at 600 mg/d continuously during consolidation. Patients in CR not eligible for HSCT were allocated to maintenance therapy consisting in weekly SC injection of Pegasys 45 µg and continuous administration of imatinib 400 mg per day for 2 years.

This is an open-label, Phase I study to determine the highest amount of the study drug, ON 01910.Na, that can be safety given to patients with high risk myelodysplastic syndromes (MDS) or refractory leukemias. Patients will receive ON 01910.Na (at a starting dose of 650 mg/m2) intravenously by 3-day continuous infusion once every 2 weeks. Successive courses will use longer infusion times and/or higher doses of the drug until toxicity, effectiveness, or ineffectiveness is recognized. In addition, the amount of drug in the blood will be measured, any antitumor activity will be documented, and the biological effect of ON 01910.Na on cell-cycle pathways will be evaluated in peripheral blood mononuclear cells.

The goal of this clinical research study is to find out if IL-11 (NeumegaTM) may increase the platelet count in patients with Chronic myeloid leukemia (CML) who develop low platelet counts while receiving therapy with imatinib mesylate (Gleevec, STI571), or other tyrosine kinase inhibitors such as AMN107, dasatinib, or SK1606. Primary Objective: 1. To determine efficacy of low-dose interleukin-11, (IL-11, oprelvekin, NeumegaTM) in improving the thrombocytopenia associate with imatinib or other tyrosine kinase inhibitor therapy in patients with CML. Secondary Objective: 1. To determine the safety of low-dose IL-11 in patients with CML and thrombocytopenia associated with imatinib or other tyrosine kinase inhibitors
