Active clinical trials for "Preleukemia"

The purpose of this study is to find a new way to treat Acute Myeloid Leukemia (AML), Myelodysplastic Syndrome (MDS) and Chronic Myelomonocytic Leukemia (CMML). All the drugs are used to treat AML and MDS but are not usually combined together. The investigators are looking at both the safety and Efficacy of each combination.

The goal of this clinical research study is to learn if 5-azacitidine and sorafenib can control the disease in patients with AML or MDS. The safety of this drug combination will also be studied.

RATIONALE: Sorafenib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth or by blocking blood flow to the cancer. Drugs used in chemotherapy, such as cytarabine, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving sorafenib together with cytarabine may kill more cancer cells. PURPOSE: This phase I/II trial is studying the side effects and best dose of giving sorafenib together with cytarabine and to see how well it works in treating older patients with acute myeloid leukemia or high-risk myelodysplastic syndrome.

The goal of this clinical research study is to determine the safety and effects of giving a special kind of immune cells called "alloreactive natural killer (NK) cells" with high dose chemotherapy and allogeneic hematopoeitic stem cell transplantation with the goal of defining the maximum tolerated dose of NK cells. The NK cells will be donated from a relative of yours who has certain genetic type in their blood called HLA, that almost matches yours. The stem cells you will receive will come from a separate HLA matched (HLA A, B, C, DR) relative or unrelated donor. The safety of this treatment will also be studied.

This phase I/II trial studies the side effects and best dose of decitabine when given together with filgrastim, cladribine, cytarabine, and mitoxantrone hydrochloride in treating patients with acute myeloid leukemia or myelodysplastic syndrome that is newly diagnosed, has come back or has not responded to treatment. Drugs used in chemotherapy, such as decitabine, cladribine, cytarabine, and mitoxantrone hydrochloride 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. Colony-stimulating factors, such as filgrastim, may increase the production of blood cells and may help the immune system recover from the side effects of chemotherapy. Decitabine, filgrastim, cladribine, cytarabine, and mitoxantrone hydrochloride may work better in treating patients with acute myeloid leukemia and myelodysplastic syndrome.

The main objectives of this study are to evaluate the side effects of MKC-1 and to determine a safe dose of MKC-1 for future studies in patients with hematological malignancies

This trial is studying the side effects and how well giving cyclophosphamide and busulfan followed by donor stem cell transplant works in treating patients with myelofibrosis, acute myeloid leukemia, or myelodysplastic syndrome. Giving chemotherapy, such as cyclophosphamide and busulfan, before a donor stem cell transplant helps stops the growth of cancer cells. It also helps stop the patient's immune system from rejecting the donor's stem cells. The donated stem cells may replace the patient's immune cells and help destroy any remaining cancer cells (graft-versus-tumor effect). Sometimes the transplanted cells from a donor can also make an immune response against the body's normal cells. Giving tacrolimus and methotrexate after the transplant may stop this from happening

This randomized phase III trial is studying donor bone marrow transplant with or without G-CSF to compare how well they work in treating young patients with hematologic cancer or other diseases. Giving chemotherapy and total-body irradiation before a donor bone marrow 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 methotrexate and tacrolimus or cyclosporine before and after transplant may stop this from happening. It is not yet known whether donor bone marrow transplant is more effective with or without G-CSF in treating hematologic cancer or other diseases.

The goal of this clinical research study is to compare the effectiveness of 2 different doses of the drug clofarabine that can be given on a weekly schedule for the treatment of Myelodysplastic Syndrome (MDS). The safety of these two doses will also be compared. Primary Objective: Compare the response rates of two dose schedules of clofarabine in MDS. Secondary Objective: Compare response durations, survivals and side effects of the two schedules.

RATIONALE: 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. Monoclonal antibodies, such as gemtuzumab ozogamicin, can block cancer growth in different ways. Some block the ability of cancer cells to grow and spread. Others find cancer cells and help kill them or carry cancer-killing substances to them. Tipifarnib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Giving combination chemotherapy together with gemtuzumab ozogamicin or tipifarnib may kill more cancer cells. PURPOSE: This randomized phase II/III trial is studying different combination chemotherapy regimens to compare how well they work when given with or without gemtuzumab ozogamicin or tipifarnib in treating patients with acute myeloid leukemia or high-risk myelodysplastic syndromes.
