Active clinical trials for "Preleukemia"

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

The different mechanisms of action between Antithymocyte globulin and cyclosporine can improve the effectivity when both are used in combination in patients with myelodysplastic syndrome.

The goal of this study is to see if there is a benefit to giving chemotherapy and then natural killer (NK) cells. The NK cells must come from a family member who shares half of the patients HLA proteins. NK cells are a type of white blood cell. They can recognize and kill abnormal cells in the body. Patients whose blood cancer is not cured with a stem cell transplant do not have standard treatment options. Studies have shown that NK cells from a donor can be given safely and can be helpful in treating some blood diseases. These NK cells are collected from the patients donor and purified using a separation system called CliniMACS that has been used safely in previous studies and is used in this study with the approval of the Federal Food and Drug Administration. The researchers want to find out what effects the NK cells will have on blood cancer and bone marrow function and how to maximize its benefits in treating blood cancers. The researchers hope that giving chemotherapy and then NK cells will be a better treatment for the disease than the current available treatment options.

A phase I/II study to explore the feasibility and efficacy of autologous CIK cells in patients with acute myeloid leukemia (AML)/ high grade myelodysplastic syndrome (MDS) Group 1: As adjuvant therapy in minimal residual disease state after autologous PBSCT. Group 2: As an adoptive immunotherapy in untreated disease state when conventional therapy with curative intent is not applicable

RATIONALE: Combinations of biological substances in DT388IL3 fusion protein may be able to carry cancer killing substances directly to the cancer cells. PURPOSE: This phase I/II trial is studying the side effects and best dose of DT388IL3 fusion protein and to see how well it works in treating patients with acute myeloid leukemia or myelodysplastic syndromes.

This phase II trial is studying how well giving MS-275 together with GM-CSF works in treating patients with myelodysplastic syndrome and/or relapsed or refractory acute myeloid leukemia. MS-275 may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the cancer. Colony-stimulating factors, such as GM-CSF, may increase the number of immune cells found in bone marrow or peripheral blood. Giving MS-275 together with GM-CSF may be an effective treatment for myelodysplastic syndrome and acute myeloid leukemia

RATIONALE: Giving chemotherapy, such as clofarabine, melphalan, and thiotepa, before a donor stem cell transplant helps stop the growth of cancer or abnormal cells. It also helps stop the patient's immune system from rejecting the donor's stem cells. When the healthy stem cells from a donor are infused into the patient they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets. Sometimes the transplanted cells from a donor can also make an immune response against the body's normal cells. Giving tacrolimus and mycophenolate mofetil before the transplant may stop this from happening. PURPOSE: This phase I/II trial is studying the side effects and best dose of clofarabine when given together with melphalan and thiotepa, followed by a donor stem cell transplant and to see how well it works in treating patients with high-risk and/or advanced hematologic cancer or other disease.

RATIONALE: Bexarotene may help cancer or abnormal cells become more like normal cells, and to grow and spread more slowly. Colony-stimulating factors, such as GM-CSF, may increase the number of immune cells found in bone marrow or peripheral blood. Giving bexarotene together with GM-CSF may be an effective treatment for myelodysplastic syndrome (MDS) or acute myeloid leukemia. PURPOSE: This phase II trial is studying how well giving bexarotene together with GM-CSF works in treating patients with MDS or acute myeloid leukemia.

The goal of this clinical research study is to find out if decitabine, given with or without valproic acid, can help to control AML or MDS. The safety of both treatments will also be studied.

RATIONALE: Giving chemotherapy, such as fludarabine and busulfan, before a donor peripheral stem cell transplant helps stop the growth of cancer or abnormal cells. It also helps stop the patient's immune system from rejecting the donor's stem cells. When the healthy stem cells from a donor are infused into the patient they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells. Giving a monoclonal antibody, alemtuzumab, before the transplant and tacrolimus after the transplant may stop this from happening. PURPOSE: The phase I portion of this trial identified the maximum tolerated dose of busulfan after treating 40 patients on a dose-escalation scheme. We are now treating an additional 26 patients on the phase II portion of the trial at a Pharmacokinetic (PK)-directed dose of total area under curve (AUC) 6912 micrometer (uM)-min/24 hours. We transitioned to the Phase II portion of the study in October 2009.
