Filter by:The purpose of this study is to determine whether idarubicin dose intensification is safe and effective as a remission induction therapy for acute myeloid leukemia.
RATIONALE: Studying samples of blood, tissue, and bone marrow from patients with cancer in the laboratory may help doctors learn about changes that occur in RNA and identify biomarkers related to cancer. PURPOSE: This research trial studies RNA samples from patients with Down syndrome and acute myeloid leukemia or other transient myeloproliferative disorder.
Patients will be receiving a stem cell transplant as treatment for their disease. As part of the stem cell transplant, patients will be given very strong doses of chemotherapy, which will kill all their existing stem cells. A close relative of the patient will be identified, whose stem cells are not a perfect match for the patient's, but can be used. This type of transplant is called "allogeneic", meaning that the cells are from a donor. With this type of donor who is not a perfect match, there is typically an increased risk of developing GvHD, and a longer delay in the recovery of the immune system. GvHD is a serious and sometimes fatal side-effect of stem cell transplant. GvHD occurs when the new donor cells (graft) recognize that the body tissues of the patient (host) are different from those of the donor. In this study, investigators are trying to see whether they can make special T cells in the laboratory that can be given to the patient to help their immune system recover faster. As a safety measure, we want to "program" the T cells so that if, after they have been given to the patient, they start to cause GvHD, we can destroy them ("suicide gene"). Investigators will obtain T cells from a donor, culture them in the laboratory, and then introduce the "suicide gene" which makes the cells sensitive to a specific drug called AP1903. If the specially modified T cells begin to cause GvHD, the investigators can kill the cells by administering AP1903 to the patient. We have had encouraging results in a previous study regarding the effective elimination of T cells causing GvHD, while sparing a sufficient number of T cells to fight infection and potentially cancer. More specifically, T cells made to carry a gene called iCasp9 can be killed when they encounter the drug AP1903. To get the iCasp9 gene into T cells, we insert it using a virus called a retrovirus that has been made for this study. The AP1903 that will be used to "activate" the iCasp9 is an experimental drug that has been tested in a study in normal donors with no bad side-effects. We hope we can use this drug to kill the T cells. The major purpose of this study is to find a safe and effective dose of "iCasp9" T cells that can be given to patients who receive an allogeneic stem cell transplant. Another important purpose of this study is to find out whether these special T cells can help the patient's immune system recover faster after the transplant than they would have otherwise.
RATIONALE: Low-dose cytarabine works in a minority of elderly patients with an acute myeloid leukemia unfit for intensive induction therapy by killing of leukemia cells. Addition of BIBF1120 to low-dose cytarabine might enhance the killing of leukemia cells. PURPOSE: This phase I / II trial is studying how safe BIBF1120 can be combined with low-dose cytarabine (phase I) and how well the combination of low-dose cytarabine and BIBF1120 works in elderly patients with acute myeloid leukemia unfit for intensive chemotherapy (phase II).
Although transplant results for AML in complete remission (CR) at the time of transplant have improved, transplant results for non-remission AML have been quite poor. Most multi-center studies have focused on standard risk AML patients and not many studies have been done in this population of patients with non-remission AML. There are a large number of older patients with non-remission AML because the complete remission rate with induction chemotherapy decreases with age. Such older patients do not tolerate conventional full intensity conditioning regimens. Thus, an effective and tolerable conditioning regimen for non-remission AML is a great unmet need for current transplant practice. From the investigators earlier study, it is suggested that replacing Fludarabine of standard FluBu4 regimen by Clofarabine (a related drug with much more potent anti-leukemia effect) in the transplant conditioning regimen may potentiate the anti-tumor activity of the conditioning regimen without adding significant toxicity, a goal of new conditioning regimen development. The investigators expect to enroll a total of 75 patients from about fifteen sites. The investigators main objective is to confirm both the safety and efficacy as measured by one-year overall survival, of the CloBu4 combination as full intensity conditioning for non-remission acute myelogenous leukemia.
The study's primary objective is to determine the maximum tolerated dose (MTD) and dose-limiting toxicity (DLT) of Panobinostat when administered within 150 days after hematopoietic stem cell transplantation (HSCT) and given in conjunction with standard immunosuppressive therapy after HSCT for patients with high-risk Myelodysplastic Syndrome (MDS) or Acute Myeloid Leukemia (AML). Secondary objectives are - To determine safety and tolerability of panobinostat - To determine overall and disease-free survival at 12 months after HSCT - To evaluate immunoregulatory properties of panobinostat - To evaluate patient-reported health-related quality of life (HRQL) The hypothesis of this study is that panobinostat can be an effective drug in preventing relapse of MDS and AML patients with high-risk features after hematopoietic stem cell transplantation with reduced-intensity conditioning (RIC-HSCT) while at the same time reducing graft-versus-host disease (GvHD) with preservation of graft-versus-leukemia (GvL) effect.
This is a worldwide, three-part (Part 1: open-label, Part 2: randomized, double-blind, Part 3: extension), multi-center study to evaluate the effect of eltrombopag in subjects with myelodysplastic syndromes (MDS) or acute myeloid leukemia (AML) who have thrombocytopenia due to bone marrow insufficiency from their underlying disease or prior chemotherapy. This objective will be assessed by a composite primary endpoint that consists of the following: the proportion of ≥Grade 3 hemorrhagic adverse events, or platelet counts <10 Gi/L, or platelet transfusions. Patients with MDS or AML and Grade 4 thrombocytopenia due to bone marrow insufficiency from their underlying disease or prior chemotherapy will be enrolled in the study. No low or intermediate-1 risk MDS subjects will be enrolled in the study. Subjects must have had at least one of the following during the 4 weeks prior to enrolment: platelet count <10 Gi/L, platelet transfusion, or symptomatic hemorrhagic event. Supportive standard of care (SOC), including hydroxyurea, will be allowed as indicated by local practice throughout the study. The study will have 3 sequential parts. Subjects who are enrolled in Part 1 (open-label) cannot be enrolled in Part 2 of the study (randomized, double-blind); however, subjects who complete the treatment period for Part 1 or Part 2 (8 and 12 weeks, respectively) will continue in Part 3 (extension) if the investigator determines that the subject is receiving clinical benefit on treatment.
Comparing flavopiridol with ara-C and mitoxantrone (FLAM) to traditional chemotherapy used to treat newly diagnosed AML of ara-C and daunorubicin (7+3).
This randomized phase III trial studies how well bortezomib and sorafenib tosylate work in treating patients with newly diagnosed acute myeloid leukemia. Bortezomib and sorafenib tosylate may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving bortezomib and sorafenib tosylate together with combination chemotherapy may be an effective treatment for acute myeloid leukemia.
Results of actual treatment in ALL are not optimal. New prognostic factors, which may determine clinical & molecular response are required. Hyper-CVAD is an internationally accepted schema for such patients. The objective of this pilot study is to evaluate polymorphisms regarding RFC (reduced folate carrier) and MTHFR enzyme, which may affect the function of these proteins, and therefore the intracellular bioavailability of methotrexate. Also, the expression levels of hENT1 and dCK will be evaluated, since such genes codify for citarabine intracellular transport and activation, respectively. Clinical characteristics will be tabulated and analyzed for responders & non-responders patients. Uni- & multivariate analysis will be done to evaluate factors influencing on response and survival.
