Active clinical trials for "Leukemia, Myeloid, Acute"

Long term disease-free survival (DFS) of patients with acute myeloid leukemia (AML) is still poor. Recently, so-called "targeted therapy" for cancer has been introduced to the treatment of patients with AML. This phase II clinical trial will explore the efficacy, safety, and pharmacodynamics of the tyrosine kinase inhibitor pazopanib in patients with relapsed or refractory AML or patients with AML who are not eligible for intensive treatment. Biomarker studies will be included to study whether the targets are indeed inhibited and whether this leads to decreased BM angiogenesis. Toxicity assessments will be included, and the antileukemic effectiveness will be studied.

This randomized phase II trial studies how well giving decitabine with or without bortezomib works in treating older patients with 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,by stopping them from dividing, or by stopping them from spreading. Bortezomib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. It is not yet known whether decitabine works better when given with or without bortezomib in treating acute myeloid leukemia.

The purpose of this study is to determine the pharmacokinetics (PK) of decitabine administered to patients with myelodysplastic syndrome (MDS) or acute myeloid leukemia (AML).

This is a single institution study of combining decitabine with fludarabine and busulfan in the setting of allogeneic stem cell transplantation. A study population of 20 subjects will be enrolled from The John Theurer Cancer Center at Hackensack University Medical Center. Subjects who are eligible to receive allogeneic hematopoietic stem cell transplantation according to the eligibility criteria will be consented and enrolled. Subjects will receive treatment with decitabine followed by reduced intensity fludarabine and busulfan prior to allogeneic stem cell transplantation. Subjects will be followed until 1 year post transplantation to assess stability of engraftment, toxicity, progression free survival, and disease response

For patients with leukemia who have not responded to or have progressed after an initial response to standard therapy, therapeutic options are limited. Although responses to standard regimens do occur, durable remissions are achieved infrequently and current regimens are not curative in the majority of patients. Identification of active agents in patients with relapsed Acute Myeloid Leukemia (AML) ultimately affords the potential for use upfront as a component of induction regimens that may translate to improved outcome. Therefore, development of new agents is of critical importance. This study will look at a new, investigational agent, ON 01910.Na, to determine if it has the potential to help Patients with AML and Acute Lymphocytic Leukemia (ALL) and transformed Myeloproliferative Neoplasms.

The purpose of this study is to compare the effects, good and/or bad, of posaconazole and micafungin in preventing fungal infections after chemotherapy for acute leukemia or myelodysplastic syndrome. When people take chemotherapy, they are more likely to get infections. Posaconazole has been approved for the prevention of fungal infections in patients who receive induction chemotherapy for acute leukemia and myelodysplastic syndrome. Posaconazole is available only as an oral suspension and has to be given with food. After chemotherapy, many patients are not able to tolerate food or oral medication because of severe mucositis. Patients unable to tolerate food and oral medications cannot take posaconazole. Micafungin is an antifungal medication that is given only intravenously. Micafungin is approved for the treatment of certain fungal infections and for preventing fungal infections in patients who receive bone marrow transplant. The investigators know that micafungin is safe. Micafungin has not been tested for the prevention of fungal infections in patients receiving chemotherapy for acute leukemia and myelodysplastic syndrome. Because micafungin is given by vein, it can be given even in patients who cannot take food or medications by mouth after chemotherapy. In this study the investigators want to compare micafungin to posaconazole when given for the prevention of fungal infections in leukemia and myelodysplastic syndrome patients.

The purpose of the study is to determine if participants who receive the GVHD prophylaxis medication pentostatin will have less severe hepatic toxicities than those receiving MTX. The study is estimated to have sufficient statistical power to ascertain at least a 20% improvement in day 42 NCI CTC grade 2 or above hepatic toxicity-free survival in pentostatin recipients.

Background: One way to treat certain cancers of the blood and immune system is to give a patient stem cells from the bone marrow of a donor whose genes are very similar but not identical to the patients. One problem with these transplants is that the new immune cells may not work as well in the recipient as they did in the donor. The result may be that the immune system will not work as well. This can increase the risk of severe infections and other complications. Researchers are studying the use of drugs that lower hormone levels and may allow the immune system to recover in a way that improves white blood cell function. In this study they will be looking at the drug leuprolide, a drug that lowers estrogen or testosterone levels, to see if it might improve the function of the newly transplanted cells. Objectives: To determine whether leuprolide improves immune system function after bone marrow transplant from a donor with similarities in their immune cells (matched to each other). To evaluate the effectiveness of a nuclear medicine test with a radiotracer drug 3-deoxy-3 18F-fluorothymidine (FLT) in imaging studies. FLT will be used to image the immune system function in patients who have received bone marrow from the donor. Eligibility: People between 15 (or as young as 9 in those who have gone through puberty) and 55 years of age. These patients must have acute myelogenous leukemia, acute lymphocytic leukemia, high-risk myelodysplastic syndrome, chronic myelomonocytic leukemia, or chronic myeloid leukemia. They must also be eligible for a bone marrow transplant. Genetically similar donors for the patients who are eligible for a transplant. Design: People taking part in the study will be screened with a physical examination, medical history, blood and urine tests, and imaging studies. Patients who are not in remission or who require a bone marrow donor search may receive chemotherapy first. Donors will provide bone marrow for transplant according to standard bone marrow transplant (BMT) procedures. All women and half of the men will receive regular leuprolide doses 2 weeks before BMT to suppress hormone function. All recipients will receive 4 days of radiation followed by 2-4 days of chemotherapy before the bone marrow transplant (depending on age). Recipients will also receive other drugs to prevent transplant rejection and other complications of transplantation. Recipients will be monitored in the hospital for 4 weeks after transplant with blood tests and other studies. Some recipients will have an imaging study with FLT during the protocol. These imaging studies will take place before the transplant, on days 5 and 28 after transplant, and at a later time to be determined by the study researchers. Following discharge, participants will be monitored closely for up to 6 months, with regular but less frequent followup visits for at least 5 years. Study-related medications, including vaccinations for the new immune system, will be provided by the National Institutes of Health during the hospital stay and after discharge.
