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

Assessment of patients response and expression levels of CITED2 and HIF2a genes on adding pioglitazone to imatinib therapy.

In this phase I pilot study, it is planned to investigate the feasibility and safety of adding an interferon therapy to an preexisting imatinib treatment in patients with chronic phase chronic myeloid leukaemia. The participating patients have already reached a response during their imatinib therapy (CCyR) but have still a detectable disease (no molecular response MR 4.5 or better).

The purpose of this study is to demonstrate the bioequivalence of the clinical tablet formulation (100 mg x 5) to the clinical capsule formulation (100 mg x 5) in healthy subjects under fed condition (Cohort 1) and to investigate the effect of a high-fat meal on the pharmacokinetics of bosutinib after administration of the proposed commercial tablet formulation (100 mg x 4) in healthy subjects (Cohort 2).

Hematopoietic progenitor cell (HPC- primitive cells in the blood, bone marrow and umbilical cord that can restore the bone marrow) transplant can be a curative therapy for the treatment of hematologic malignancies (a disease of the bone marrow and lymph nodes). The source of cells used for the transplant comes from related (sibling) and in cases where there is no sibling match, from unrelated donors through the National Marrow Donor Program. The availability of a suitable donor can be a significant obstacle for patients who need a transplant but do not have a matched donor. Cord blood that has been harvested from an umbilical cord shortly after birth has a rich supply of cells needed for transplant. These stored cord bloods are now being used to transplant adults without a matched donor Advantages to using cord blood includes a readily available source of cells with no risk to the donor during the collection process, immediate source of cells in urgent situations (no lengthy donor work-up)and a reduction in infectious disease transmission to the recipient. One of the main disadvantages is the cord blood has a small number of cells needed for transplant. In an adult, usually two cords are needed and large recipients do not qualify because they need too many cells. This study will use two different preparative regimens (chemotherapy and radiation) followed by one or two umbilical cord units (UBC). The preparative regimen used will be chosen by the physician and is based on patient's age, disease and medical condition at the time of transplant. Multiple objectives for this study include disease-free and overall survival, treatment related mortality, rate of cells taking hold, and the incidence and severity of the transplant complication called graft versus host disease (GVHD).

This randomized phase II trial studies how well donor umbilical cord blood transplant with or without ex-vivo expanded cord blood progenitor cells works in treating patients with acute myeloid leukemia, acute lymphoblastic leukemia, chronic myelogenous leukemia, or myelodysplastic syndromes. Giving chemotherapy and total-body irradiation before a donor umbilical cord blood transplant helps stop the growth of cancer cells. It may also stop the patient's immune system from rejecting the donor's cells. When the healthy stem cells and ex-vivo expanded cord blood progenitor cells are infused into the patient they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets. It is not yet known whether giving donor umbilical cord blood transplant plus ex-vivo expanded cord blood progenitor cells is more effective than giving a donor umbilical cord blood transplant alone.

The purpose of this study is to assess the safety and efficacy of ponatinib in Japanese patients with chronic myeloid leukemia (CML) who have experienced failure of dasatinib or nilotinib or with Ph+ acute lymphoblastic leukemia (ALL) following failure of prior tyrosine kinase inhibitors (TKIs).

This open-label, extension study is designed to provide continuing treatment with RO5045337 to participants who have completed parent studies NO21279 (NCT00623870), NO21280 (NCT00559533), NP25299 (NCT01164033), NP28021 (NCT01605526) or NP28023 (NCT01635296). Participants are eligible to participate in this study if they have completed required Phase 1 study assessments for primary objectives of respective parent protocol and are having evidence of clinical benefit (as defined by the parent protocol). Participants will continue the most similar dose and formulation available (which does not exceed the maximum tolerated dose [MTD] or the maximum safely administered dose for that formulation during Phase 1) and the same schedule of RO5045337 treatment that they were receiving at the time of transitioning from the parent clinical study protocol.

This is a phase I single center dose escalation study with an extension at the best available dose to determine the tolerability of inducible regulatory T cells (iTregs) when given to adult patients undergoing non-myeloablative HLA-identical sibling donor peripheral blood stem cell (PBSC) transplantation for the treatment of a high risk malignancy. Up to 5 dose cohorts will be tested. Once the tolerable dose is determined for iTregs, enrollment will continue with an additional 10 patients using sirolimus/Mycophenolate mofetil (MMF) graft-versus-host disease (GVHD) prophylaxis to gain further safety information and to provide pilot data in this treatment setting.

Patients with newly diagnosed CML have excellent outcomes with tyrosine kinase inhibitors (TKI). However, a few patients will be cured with TKIs alone, and thus need continued life-long treatment. Some patients achieve complete molecular remission (CMR), and this rate is higher with second generation TKIs compared with imatinib. Some experience with drug discontinuation in CMR has been derived from a few small studies, most notably the French STIM study. Approximately 40 % of patients with a minimum of two years in MR4.5 (4.5 log reduction in molecular response) can stop imatinib without relapse, indicating possible cure. To increase the non-relapse rate is of major importance. To achieve a permanent "cure" without stem cell transplantation is presently the most relevant goal of clinical studies in CML. The investigators hypothesize that to significantly increase cure rates in CML, therapy should eradicate leukemic stem cells and/or induce or restore anti-CML immunity. Second generation TKIs may have a more profound effect on the stem cell pool as compared to imatinib. This is assessed in our current randomized study with a reduction in leukemic stem cell burden as the primary endpoint (NordCML006). Interferon-alpha (IFN) has a prominent immunomodulatory and antiproliferative mode of action, and has also activity in stem cells. Pegylated IFN in combination with imatinib results in improved therapy responses as compared to imatinib monotherapy. This advantage may translate into higher cure rates. Dasatinib has a unique dual mechanism of action: it is the most potent of available TKIs and induces immunological effects that are different from those of IFN. Both of these drugs may have immunological adverse-effects when used as a monotherapy. However, immunological adverse-effects may also be markers of anti-leukemia efficacy. A combination of dasatinib and pegylated IFN (PegIFN) may have additive or synergistic effects and should be tested in a clinical study.

The main purpose of this trial is to assess the efficacy and safety of sitagliptin in enhancing engraftment following umbilical cord blood transplantation (recovery of blood counts after transplant).
