Active clinical trials for "Leukemia, Myeloid, Acute"

AML of the older patient constitutes a major unmet clinical need since the large majority will not be found eligible for induction chemotherapy. Reasons for this decision include host factors (comorbidities, reduced performance status, functional limitations due to age), leading to often poor tolerance of repeated chemotherapy courses and the unfavorable biology underlying this disease in older patients. Low dose Decitabine has shown very promising efficacy in high-risk MDS and is therefore a very promising approach also in older AML patients. Preliminary results from several centres have demonstrated excellent feasibility and good efficacy of this treatment. Therefore the investigators intend to investigate the effects of two drugs added onto low-dose Decitabine which have shown very promising synergistic effects in vitro and for which preliminary results indicate that the combination with low-dose Decitabine is very feasible.

Background: Most patients with acute lymphoblastic leukemia (ALL) and many patients with acute myelogenous leukemia (AML), chronic myelogenous leukemia (CML) and non-Hodgkin's lymphoma (NHL) have a protein called Wilm's Tumor 1 (WT1) in their cancer cells. This protein is thought to be able to influence the growth of these cancers. A vaccine made with the WT1 protein may boost the immune system to help fight these cancers in patients whose cancer cells contain the protein. Objectives: To determine the safety, effectiveness and side effects of giving the WT1 vaccine and donor white blood cells to patients with AML, ALL, CML or NHL who have previously received standard treatment and undergone stem cell transplantation. To determine the immune response to the WT1 vaccine and donor white blood cells in these patients and to determine if the response is related to the amount of WT1 protein in the patient's cancer cells. Eligibility: Patients between 1 and 75 years of age with the blood antigen human leukocyte antigen (HLA-A2) and the WT1 cancer protein who have persistent or recurrent blood cancers after stem cell transplantation. The prior stem cell transplant donor must be willing to provide additional cells, which will be used to prepare the cellular vaccines and for donor lymphocyte (white blood cell) infusions. Design: Patients are given the WT1 vaccine every 2 weeks for 6 weeks (weeks 0, 2, 4, 6, 8, 10). Each vaccination consists of two injections in the upper arm or thigh. On weeks 0, 4 and 8, patients also receive white blood cells from a donor to enhance the immune response. The cells are also given as a 15- to 30-minute infusion through a vein about 1 hour after the vaccine injection. Donor infusions are given only to patients with mild or no graft-vs-host disease resulting from their prior stem cell transplantation. Periodic physical examinations, blood and urine tests, scans to evaluate disease and other tests as needed are done for 12 months after enrollment in the study.

This is an open label, prospective, single institution dose-escalation study. The patient population includes non-induction candidate elderly patients with AML or MDS and/or patients with high-risk or relapsed/refractory AML or MDS. Five dose cohorts will be evaluated using a fixed dose of ATRA in combination with an escalating dose of dasatinib. The investigators will treat with an escalating dose of dasatinib from 70mg to 140mg daily. Dose escalation will proceed in a standard 3+3 fashion. A de-escalation to a 50 mg total daily dose of dasatinib is planned if DLT is greater than or equal to 33% is observed at the first dose level. Once the MTD for the combination of the drugs has been established, up to 6 additional patients will be enrolled at the MTD level to obtain additional safety information about the combination and to allow for preliminary laboratory correlate analysis.

This phase I trial studies the side effects and the best dose of sunitinib malate in treating human immunodeficiency virus (HIV)-positive patients with cancer receiving antiretroviral therapy. Sunitinib malate may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the tumor.

The main objective of this study is to compare conventional chemotherapy: daunorubicin and the Aracytine and this chemotherapy in combination with the monoclonal antibody used Mylotarg in divided doses.

This phase II trial is studying how well decitabine works in treating patients with previously untreated acute myeloid leukemia. Drugs used in chemotherapy, such as decitabine, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing

There was no well accepted standard of care for participants who failed or were intolerant to any of the currently approved therapies for myelodysplastic syndromes (MDS). In this study, participants were initially assigned to receive 55 or 35 milligrams (mg) of oral clofarabine daily for 5 days. After safety review of the first participants enrolled, the dose was reduced to 25 milligrams per day (mg/day) for up to 8 cycles as long as the participants continued to benefit and in the absence of progressive disease.

The overall objective is to improve the cure rate of children with newly diagnosed acute myeloid leukemia (AML) who undergo risk-adapted therapy. Stem cell transplantation (SCT) is reserved to high-risk patients defined by cytogenetics and response to chemotherapy. The efficacy and toxicity of Gemtuzumab ozogamicin (GO, Mylotarg) will be evaluated.

Association group of therapeutic specialities authorized in a remission induction treatment(FLAG-IDA: fludarabine, cytarabine, G-CSF (lenograstim) and idarubicin) and an intensive postremission treatment with authorized therapeutic association specialities and with/without Autologous Hemopoietic Stem Cell Transplantation or Bone Marrow Transplantation in Patients With High Risk Myelodysplastic Syndromes or Secondary Acute Myeloblastic Leukemia.

The study is designed with drugs used frequently in the treatment of AML, but with a new combination less toxic,and effective in AML multidrug resistant. Justification: The AML patients with primary resistance or relapsed in the first 12 months after CR, have second line chemotherapy low response rate . These patients with AML with primary resistance or relapse, that reach remission after a rescue treatment, have an interval free survival and a global survival very short Probably the resistance to the treatments is in relation to different forms expression of the MDR. Complete remission is considered valid evaluation, because every patient who should obtain a CR can be considered to be eligible for a possible curative treatment: Ara-C administration to high doses or the TPH treatment
