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.

In this study, the efficacy and safety of two radotinib doses, 300 mg twice daily and 400 mg twice daily, will be compared with imatinib 400 mg once daily in newly diagnosed patients with Philadelphia chromosome-positive (Ph+) Chronic Myelogenous Leukemia in the chronic phase (CML-CP).

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 study will assess the pharmacokinetics of nilotinib in Ph+ CML pediatric patients that are newly diagnosed or resistant or intolerant to imatinib or dasatinib or refractory or relapsed Ph+ ALL compared to the adult populations. It will also evaluate safety and activity of nilotinib as secondary objectives.

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.

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.

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.

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 with refractory hematologic malignancies, including those who develop recurrent disease after allogeneic hematopoietic stem cell transplantation (HSCT) have a dismal prognosis. Historically, both regimen-related mortality and disease recurrence have been significant causes of treatment failure in this heavily pre-treated patient population. Novel therapeutic agents that target molecular signaling mechanisms and increase the sensitivity of leukemic cells to apoptosis may clearly play a role in this setting. This study hypothesizes that interrupting the SDF-1/CXCR4 axis using the selective CXCR4 antagonist plerixafor may be useful as a leukemic stem cell mobilizing agent for patients who are refractory to standard dose chemotherapy and in relapse after an allogeneic transplant. This hypothesis is based on the dependence of leukemia cells on MSCs for survival signals as described above and on the preclinical data that suggest increased efficacy by antileukemia agents when leukemia cells are separated from MSCs. In the present trial, the study proposes to add plerixafor to enhance the conditioning regimen cytotoxicity. At this time the goal is to determine the maximum tolerated dose (MTD) of plerixafor through the process of dose limiting toxicity (DLT) evaluation. Pharmacokinetic studies will be conducted. Additional studies will quantify and the content of leukemia cells and key regulatory and effector T cell populations in the bone marrow and blood before and after exposure to this medication. If the observed outcomes of this trial are promising, it could serve as a platform on which to study further use of plerixafor as a complimentary agent with conditioning as well as other chemotherapeutic regimens for patients with relapsed or refractory hematologic malignancies.

The purpose of this study is to determine the safety, pharmacokinetics and maximum tolerated dose of ABT-348 as monotherapy and when given in combination with azacitidine.
