Active clinical trials for "Leukemia, Myeloid, Acute"

The goal of this clinical research study is to find out if Revlimid can help to control the disease in patients with relapsed/refractory acute myelogenous leukemia (AML) or high-risk myelodysplastic syndrome (MDS) with abnormalities in chromosome number 5. The safety of this treatment will also be studied.

Subjects are being asked to participate in this study because treatment of their disease requires them to receive a stem cell transplant. Stem cells or "mother" cells are the source of normal blood cells and lead to recovery of blood counts after bone marrow transplantation (BMT). Unfortunately, there is not a perfectly matched stem cell donor (like a sister or brother) and the subject's disease is considered rapidly progressive and does not permit enough time to identify another donor (like someone from a registry list that is not their relative). We have, however, identified a close relative of the subject's whose stem cells are not a perfect match, but can be used. However, with this type of donor, there is typically an increased risk of developing graft-versus-host disease (GVHD), a high rate of transplant failure, 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) recognizes that the body tissues of the patient (host) are different from those of the donor. When this happens, cells in the graft may attack the host organs, primarily the skin, liver, and intestines. The number of occurrences and harshness of severe GVHD depends on several factors, including the degree of genetic differences between the donor and recipient, the intensity of the pre-treatment conditioning regimen, the quantity of transplanted cells, and the recipient's age. In recipients of mismatched family member or matched unrelated donor stem cell transplants, there is a greater risk of GVHD so that 70-90% of recipients of unchanged marrow will develop severe GVHD which could include symptoms such as marked diarrhea, liver failure, or even death. In an effort to lower the occurrences and severity of graft-versus-host disease in patients and to lower the rate of transplant failure, we would like to specially treat the donor's blood cells to remove cells that are most likely to attack the patient's tissues. This will occur in combination with intense conditioning treatment that the patient will receive before the transplant.

This study compares overall survival between patients with acute myeloid leukemia, who are in complete remission following initial treatment with chemotherapy and whose remission is maintained either with a transplantation of stem cells obtained from a sibling or unrelated donor or with standard treatment, which is additional chemotherapy. The study hypothesis is that the group transplanted with stem cells from a donor will have a superior survival compared with patients treated with standard of care.

The purpose of this study is to find out how safe and effective the combination of Mylotarg in combination with cytarabine is in treating patients with Acute Myeloid Leukemia and advanced Myelodysplastic Syndrome over the age of 60 years.

This is a phase 1, open-label, multicenter study investigating the use of MLN518 in combination with standard chemotherapy to patients with newly diagnosed AML. Two dose levels of MLN518-200 mg and 400 mg given orally twice a day are planned for sequential evaluation in separate groups of patients. Patients assigned to the 400 mg dose level given orally twice a day of MLN518, will potentially have their dose of MLN518 adjusted on the basis of MLN518 plasma concentrations measured during the first 3 days of induction therapy. All patients will receive initial induction chemotherapy with cytarabine, 200 mg/m2/day by CIVI on Days 1 through 7, and with daunorubicin, 60 mg/m2/day by intravenous (IV) push (IV infusion if borderline cardiac function is detected) on Days 1 through 3 ("7+3"). An abbreviated cytarabine and daunorubicin regimen ("5+2") will also be used when the initial remission induction therapy fails to clear the bone marrow of blast cells (as typically detected on the Day 15 bone marrow) and a second attempt at remission induction is indicated. Patients who achieve a complete remission (CR) will receive consolidation therapy with HiDAC (standard or modified) in combination with continued MLN518 treatment. Patients remaining in continuous CR after completion of their last cycle of consolidation therapy will be permitted to continue treatment with single-agent MLN518 for 6 months thereafter.

The goal of this clinical research study is to learn if giving 5-aza-2 deoxycytidine (decitabine) in combination with Mylotarg (gemtuzumab ozogamicin) can help to control AML or high-risk MDS. The safety of this drug combination will also be studied.

Patients receiving allogeneic stem cell transplantation for hematological malignancies who suffer a relapse of their disease post-transplant have limited treatment options and a poor prognosis. With the exception of patients with chronic leukemias who may achieve prolonged remissions after donor lymphocyte infusions (DLIs), treatments using either chemotherapy or a DLI achieve less than a 10% median survival beyond 6 months. Most of these patients die of progressive leukemia, underlying the need for new therapeutic approaches. Human leukocyte antigen (HLA)-mismatched DLIs appear to possess a more potent graft-versus-leukemia (GvL) effect. However, when given after an HLA-mismatched transplant DLIs have a high risk of causing graft-versus-host disease (GvHD), which can be severe. To reduce the risk of GvHD, infusions of mismatched lymphocytes from an alternative donor may be used to avoid permanent engraftment and associated risk of GvHD. In this study, we propose to use a novel strategy to treat leukemias relapsing after HLA matched allogeneic stem cell transplantation by using haplo-identical DLIs to promote the associated antileukemic effect while minimizing the possibility of permanent engraftment and associated GvHD. To achieve only temporary engraftment and to promote disease control we will give fludarabine immunosuppression prior to the DLI. We anticipate the infusion of HLA-mismatched donor lymphocytes in this setting will produce no detectible engraftment or only temporary engraftment, but may result in a strong GvL effect regardless of engraftment outcome. We will select patients for this protocol who fall into the worst category for post-transplant relapse. Specifically, we will enroll patients with acute leukemia or MDS relapsing within 6 months of transplant, of which less than 5% survive beyond a year from relapse.

The main objective of the study is to improve outcome of younger patients (between 18-60 years) with acute myeloid leukemia and intermediate risk defined by the cytogenetics. In this population, in the absence of bone marrow transplantation, event free survival (EFS) is estimated at 35% after three years of follow-up. Adjunction of gemtuzumab ozogamycin (MYLOTARG®) to standard chemotherapy is supposed to increase EFS up to 50% at 3 years. To test this hypothesis, the Groupe Ouest Est d'Etude des Leucémies et Autres Maladies du Sang (GOELAMS ) sponsored by Nantes University Hospital leads this randomized open phase III trial in 29 French centers.

Vorinostat may stop the growth of cancer cells by blocking some of the enzymes needed for their growth. Giving the drug in different ways may kill more cancer cells. This randomized phase II trial is studying two different schedules of vorinostat to see how well they work in treating patients with acute myeloid leukemia.

This randomized phase II trial is studying 4 different tipifarnib regimens to compare how well they work in treating older patients with acute myeloid leukemia. Tipifarnib may stop the growth of cancer cells by blocking the enzymes necessary for their growth
