The purpose of this study is to find the number of natural killer (NK) cells from non-HLA matched donors that can be safely infused into patients with cancer. NK cells are a form of lymphocytes that defend against cancer cells. NK cells in cancer patients do not work well to fight cancer. In this study, the NK cells are being donated by healthy individuals without cancer who are not "matched" by human leukocyte antigen (HLA) genes to patients. After receiving these NK cells, patients may also be given a drug called ALT803. ALT803 is a protein that keeps NK cells alive, helps them grow in number and supports their cancer-fighting characteristics. HLA-unmatched NK cell infusion is investigational (experimental) because the process has not approved by the Food and Drug Administration (FDA).
This phase I trial studies the side effects and best dose of ipilimumab when given together with decitabine in treating patients with myelodysplastic syndrome or acute myeloid leukemia that has returned after a period of improvement (relapsed) or does not respond to treatment (refractory). Immunotherapy with monoclonal antibodies, such as ipilimumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Drugs used in chemotherapy, such as decitabine, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving ipilimumab and decitabine may work better in treating patients with relapsed or refractory myelodysplastic syndrome or acute myeloid leukemia.
Single-center study, prospective, phase II trial. The study objectives are : - To assess safety and pharmacokinetics of the combination of PIO and TKI in CML subjects who experience a loss of MMR following a first TKI discontinuation. - To assess survival without loss of MMR over a 12 months period following a second TKI discontinuation in subjects who achieve or maintain < MR4.5 with the combination PIO and TKI administered for at least 6 months.
This project is a Phase II clinical trial that aims at evaluating efficacy and tolerance of the combination of pioglitazone (Actos®) and imatinib mesylate (STI571, CGP57148, Gleevec®) in patients with Chronic Myelogenous Leukemia (CML) in stable major molecular response (i.e. a BCRABL/ABL ratio assessed by RTQ-PCR equal to or lower than 0.1% according to the European Leukemia Net recommendations) after at least 2 years of therapy with imatinib. Imatinib mesylate (Gleevec®) is the gold standard for the treatment of CML in chronic phase (O Brian et al. 2003, Druker et al. 2006). Despite a high efficacy of the drug, CML is not eradicated by imatinib alone in almost any of the patients. Treatment discontinuation in patients treated by imatinib and in complete molecular remission for more than 2 years yield molecular relapses within 6 months in half of the patients,indicating the persistence of CML progenitor cells. STAT5 expression is required for CML stem cell engraftment and expansion in mouse models. STAT5 is the target of the dysregulated activity of BCR-ABL in CML. Recently, Stephane Prost et al. demonstrated that PPAR-γ is a negative regulator of STAT5A and STAT5B gene expression. Data obtained suggest that PPAR-γ agonists may have potential therapeutic value in reversing myeloproliferative disorders. On the basis of our preclinical studies, we went ahead and administered pioglitazone to one patient who suffered from both diabetes type II and CML with residual disease after continuous treatment with Gleevec. The amount of BCR-ABL transcript detected by QPCR decreased dramatically during the first 3 months of combined (Gleevec + ACTOS) therapy to become undetectable thereafter until 9 months post-treatment, the latest time point assessed. This striking anecdotal result now forms the rationale for filing this formal Phase II clinical trial application.
A multicenter, open label cohort Phase 1 dose finding study to evaluate tolerability, safety, pharmacokinetics and preliminary efficacy of PF-114 for oral administration in adult patients with Philadelphia chromosome positive (Ph+) chronic myeloid leukemia (CML), which is resistant to the 2-nd generation Bcr-Abl inhibitors or has T315I mutation in the BCR-ABL gene.
Chronic myeloid leukemia (CML) is a myeloproliferative neoplasm companies with the BCR-ABL fusion gene encoded by the Philadelphia (Ph) chromosome. The BCR-ABL fusion protein(the formation of the chimeric gene BCR/ABL on chromosome 22 and a reciprocal ABL/BCR on chromosome 9,it has no expanded name) plays key role on CML leukemogenesis by activating its downstream signaling pathway of survival and proliferation. Imatinib, a targeted competitive inhibitor of a BCR-ABL tyrosine kinase, changed the clinical treatment and prognosis of CML. As its optimized generation, other tyrosine kinase inhibitors (TKIs), dasatinib and nilotinib have more potent anti-leukemic activity and less side-effect. However, acquired resistance to TKIs is one of the main obstacles to effective CML treatment and is involved in gene amplication of ABL tyrosine kinase point mutations. The outcomes of patients with these ABL tyrosine kinase point mutations have linked to worse prognosis and higher mortality generally. Metabolic adaptations are common in cancer cells, and cancer cells become more dependent on mitochondrial biogenesis. Tigecycline, as a broad-spectrum antibiotics, inhibits mitochondrial biogenesis as its an interesting "side-effect".In recent study,researchers indicated that tigecycline can eradicate cancer stem cells by targeting mitochondrial.Here, the investigators test tigecycline's anti-leukemic activity to chronic myeloid leukemia in vitro.
This phase I trial studies the side effects and best dose of oxidative phosphorylation inhibitor IACS-010759 in treating patients with acute myeloid leukemia that has come back or does not respond to treatment. Oxidative phosphorylation inhibitor IACS-010759 may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.
This phase II trial studies how well tacrolimus, bortezomib, and anti-thymocyte globulin (thymoglobulin) work in preventing low toxicity graft versus host disease (GVHD) in patients with blood cancer who are undergoing donor stem cell transplant. Tacrolimus and anti-thymocyte globulin may reduce the risk of the recipient's body rejecting the transplant by suppressing the recipient's immune system. Giving bortezomib after the transplant may help prevent GVHD by stopping the donor's cells from attacking the recipient. Giving tacrolimus, bortezomib, and anti-thymocyte globulin may be a better way to prevent low toxicity GVHD in patients with blood cancer undergoing donor stem cell transplant.
Invasive fungal disease (IFD) is an important cause of mortality and morbidity in patients undergoing intensive chemotherapy or transplantation. This current study aims to assess the impact of prophylactically using the broad-spectrum anti-fungal agent posaconazole on the incidence of IFD in high risk patients with aplastic anaemia and those undergoing intensive chemotherapy, for example for acute myeloid leukaemia, and allogeneic stem cell transplantation.
