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

RATIONALE: Giving high doses of chemotherapy drugs, such as busulfan and cyclophosphamide, 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, methylprednisolone, and methotrexate after transplant may stop this from happening. PURPOSE: This clinical trial studies high-dose busulfan and high-dose cyclophosphamide followed by donor bone marrow transplant in treating patients with leukemia, myelodysplastic syndrome, multiple myeloma, or recurrent Hodgkin or Non-Hodgkin lymphoma.

This is a two-part safety and efficacy study of SKI-606 in subjects who have Philadelphia chromosome positive leukemias (CML). Part 1 will be a dose-escalation study, in which an escalating dose of SKI-606 (Bosutinib), up to 600 mg, will be studied in subjects with imatinib resistant/refractory or imatinib intolerant chronic phase CML. Part 2 will evaluate the safety and efficacy of the maximum tolerated dose (MTD) of SKI-606 (Bosutinib)identified in Part 1 of the study.

This is an extension of our ongoing clinical trial using ex vivo expanded autologous Cytokine-induced killer (CIK) cells as an adoptive cellular immunotherapy for haematological malignancies. The pre-existing clinical trial targets patient with acute myeloid leukemia or MDS, and relapsed disease post allogeneic transplant. Chronic myeloid leukemia (CML) is a disease with good response to kinase inhibitors. There are however patients in transformed phase of the disease who do not respond to these treatment. A small proportion of patients with response to Imatinib may develop mutations resulting in drug resistance. In addition, the vast majority of patients with a good response to the kinase inhibitors still have persistent CML cells detectable at a molecular level. It is known that the CML progenitors are not sensitive to the kinase inhibitors. On the other hand, immune mediated mechanism is known to be able to eradicate CML as shown by efficacy of donor lymphocyte infusion in the allogeneic transplant setting. Early clinical trials have shown clearance of bcr-abl using peptide vaccination. There is also convincing mouse data showing eradication of CML at molecular level by autologous CIK cells, but no clinical trial has been done using CIK cells for CML. We therefore plan to expand our current CIK trial to include CML as a disease, for CML patients with various degree of response to the kinase inhibitors which have already offered its maximal effect. We aim to study whether autologous CIK cells may further improve disease response, either in the eradiation of minimal residual disease, or in conjunction with chemotherapy for control of high tumour load disease.

RATIONALE: Nilotinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. PURPOSE: This phase II trial is studying how well nilotinib works in treating patients with newly diagnosed chronic phase chronic myelogenous leukemia.

RATIONALE: Dasatinib and vorinostat may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Giving dasatinib together with vorinostat may kill more cancer cells. PURPOSE: This phase I trial is studying the side effects and best dose of dasatinib when given together with vorinostat in treating patients with accelerated phase or blastic phase chronic myelogenous leukemia or acute lymphoblastic leukemia.

Current therapeutic results in advanced chronic myeloid leukemia (CML) and Ph+ acute lymphoblastic leukemia (ALL) are rather disappointing. Most of these patients will eventually undergo allogeneic stem cell transplantation. Nilotinib is a novel TKI tyrosine kinase inhibitor with 30 fold more potency than Imatinib. Based on previous preliminary experience the author we rationalize that Nilotinib therapy pre- allogeneic transplantation for patients with advanced CML and Ph+ALL will reduce tumor mass pre- transplant achieving a state of minimal residual disease (MRD) and therefore may improve transplantation outcome without increasing toxicity. In addition it will allow time for improving patient medical condition and for finding an unrelated donor which will enable allogeneic transplantation , and to induce anti tumor effect post PBSC w\o DLI ( donor lymphocyte infusion)

This is a phase II, multi-center, open-label, non-randomized trial. During Part 1 of the trial, patients will receive once daily oral administration of STI571 at a dose of 600 mg for 24 weeks. After completing 24 weeks of therapy, patients may be eligible to receive additional therapy during Part 2 of the trial provided that, in the opinion of the investigator, the patient has benefited from treatment with STI571 and in the absence of safety concerns. During Part 2 (which is of indefinite duration), patients will continue to receive STI571 on a daily basis until either death, the development of intolerable toxicity or the investigator feels it is no longer in the patient's best interest to continue therapy, whichever comes first.

This is a Phase II, open-label, multi-center trial designed primarily to evaluate the rate of complete or major cytogenetic response of STI571 as demonstrated by a decrease in the percentage of Ph chromosome positive cells in the bone marrow, in patients with CML who are refractory to or intolerant of interferon-alpha. During the core phase of the study, patients will receive once daily oral administration of STI571 at a dose of 400 mg, for up to 12 months. After completing 12 months of therapy patients may be eligible to receive additional therapy provided that, in the opinion of the investigator, the patient has benefited from treatment with STI571 and in the absence of safety concerns. Patients will receive STI571 on an outpatient basis. During the extended phase (which is of indefinite duration), patients may continue STI571 until either progression to accelerated phase, blast phase, death, the development of intolerable toxicity, or the investigator feels it is no longer in the patient's best interest to continue therapy, whichever comes first. The number of visits will be at a reduced frequency. Patients who discontinue study drug will be followed for survival for up to 5 years. STI571 will be considered active if the interferon-refractory patient population satisfies the target of achieving a complete or major response at a rate of at least 30%, within the preset error limits. Cytogenetic responses will be evaluated every three months and categorized as either complete (0% Ph+ chromosome cells), or major (1 to 35% Ph+ chromosome cells) responses. STI571 will be discontinued for any patient whose disease progresses to either the accelerated phase or blast crisis. A minimum of 100 patients who are interferon refractory will receive STI571 administered at a dose of 400 mg once a day. In addition, the protocol is also open for patients who are intolerant to interferon-alpha in order to get a preliminary evaluation of their response to STI571 therapy. Up to 100 intolerant patients will be enrolled. Enrollment of intolerant patients will cease at 100, or whenever the 100 refractory patients are accrued, whichever comes first.

Two-arm, randomized, open-label trial designed to evaluate the efficacy and safety of bosutinib alone compared to imatinib alone in subjects newly diagnosed with chronic phase Chronic Myelogenous Leukemia (CML). The primary endpoint is cytogenetic response rate at one year.

The prognosis of pediatric patients with hematologic malignancies whose disease is primarily refractory or those who experience a chemotherapy resistant bone marrow relapse is extremely poor. When new agents or chemotherapeutic regimens are unable to induce remission in this patient population, hematopoietic stem cell transplant (HSCT) is also a poor alternative. Thus, in this very high risk group, additional attempts at remission induction with various combinations of chemotherapy alone will unlikely improve outcome and will contribute to overall toxicity. Alternative therapies are needed in these patients with chemotherapy resistant disease. Immunotherapy with natural killer (NK) cell infusion has the potential to decrease toxicity and induce hematologic remission. NK cells can kill target cells, including leukemia cells, without prior exposure to those cells. In patients undergoing allogeneic HSCT, several studies have demonstrated the powerful effect of NK cells against leukemia. Furthermore, NK cell infusions in patients with primary refractory or multiple-relapsed leukemia have been shown to be well tolerated and void of graft-versus-host disease effects. In this high risk group, complete leukemic remission has been observed in several of these patients after NK cell infusion. With the current technology available at St. Jude, we have developed a procedure to purify NK cells from adult donors. This protocol will assess the safety of chemotherapy and IL-2 administration to facilitate transient NK-cell engraftment in research participants who have chemotherapy refractory hematologic malignancies including acute lymphoblastic leukemia, chronic myelogenous leukemia, juvenile myelomonocytic leukemia, myelodysplastic syndrome, or non-Hodgkin's lymphoma. In this same cohort, we will also intend to explore the efficacy of NK cells infused in those participants who have chemotherapy refractory disease.
