View clinical trials related to Chronic Myeloid Leukemia.
Filter by:Chronic myelogenous leukemia (CML) is a chronic myeloproliferative disorder characterized by a translocation between chromosome 9 and 22, leading to a pathogenic tyrosine kinase signal transduction protein. CML can be treated with tyrosine kinase inhibitors (TKIs), which inhibit BCR/ABL kinase, such as imatinib. In about 20% of CML patients who are treated by imatinib, a complete cytogenetic response cannot be achieved. The other two novel TKIs (dasatinib and nilotinib), achieve higher rates of complete cytogenetic response and they are proposed as second-line therapy for imatinib-resistant patients or for those who do not tolerate imatinib. Dasatinib inhibits BCR/ABL kinase in about >300 times in vitro in more than imatinib and also inhibits several other kinases, including the Src family. Src tyrosine kinase is crucial for potassium channel function in human pulmonary arteries. Imatinib and nilotinib do not inhibit the Src. Incident cases of precapillary PH have been reported in patients who have CML treated with the dasatinib. Improvements were usually observed after withdrawal of dasatinib. This study is designed to identify incident cases of dasatinib-associated PH and describe pulmonary vascular changes induced by dasatinib. As comparison population will be patients who receive another second-line TKI (nilotinib).

This pilot phase II trial studies how well giving vorinostat, tacrolimus, and methotrexate works in preventing graft-versus-host disease (GVHD) after stem cell transplant in patients with hematological malignancies. Vorinostat, tacrolimus, and methotrexate may be an effective treatment for GVHD caused by a bone marrow transplant.
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 phase II trial studies reduced-intensity conditioning before donor stem cell transplant in treating patients with high-risk hematologic malignancies. Giving low-doses of chemotherapy and total-body irradiation before a donor stem cell transplant helps stop the growth of cancer cells. It may also stop the patient's immune system from rejecting the donor's stem cells. The donated stem cells may replace the patient's immune cells and help destroy any remaining cancer cells (graft-versus-tumor effect). Giving an infusion of the donor's T cells (donor lymphocyte infusion) before the transplant may help increase this effect.
Primary objectives: - To establish the maximum tolerated dose (MTD), and the recommended Phase 2 dose (RP2D) of BEZ235 when administered twice daily (BID) as a single agent in patients with relapsed or refractory acute leukemia - To determine the dose-limiting toxicity (DLT) Secondary objectives: - Assess the safety and tolerability of daily oral administration of BEZ235 with a BID schedule - To describe preliminary anti-leukemic activity of BEZ235 in patients with acute leukemia - To correlate changes in pharmacodynamic biomarkers with basic pharmacokinetic data Exploratory objectives: - To assess pre-treatment phosphatidylinositol 3-kinase (PI3K) pathway-related genes in blast cells and all other malignant cells derived from blood or bone marrow. - To assess the pharmacodynamic changes in components of the PI3K-protein kinase B (AKT)-mTOR pathway in bone marrow following treatment as potential predictive biomarkers of pharmacodynamic (PD) activity of BEZ235 in association with clinical responses. - To identify potential resistance mechanisms and biomarkers that may correlate with efficacy and response from blood and bone marrow samples pre-and post-treatment in case of resistance

The purpose of this study was to allow continued use of nilotinib in patients who were on nilotinib treatment in a Novartis-sponsored, Oncology Clinical Development & Medical Affairs (CD&MA) study and were benefiting from the treatment as judged by the investigator
Analyze the results of conditioning with once-daily dose intravenous busulfan and fludarabine in patients undergoing HLA identical sibling Allogeneic HSCT for myeloid malignancies.
Advances in Chronic Myeloid Leukemia (CML) therapy led to an expected survival prolongation of > 20 years after diagnosis. So far, discontinuation of tyrosine kinase inhibitors led to recurrence of disease in the majority of patients. The trial aims to improve treatment strategies in CML by improving induction therapy and deescalating maintenance therapy using low dose IFN as inducer of immunosurveillance. The trial will provide important data on the duration of active therapy in CML patients. Considering the rapidly increasing prevalence of CML this is of individual but also socioeconomic importance.
