Idarubicin, Cytarabine, and Tipifarnib in Treating Patients With Newly Diagnosed Myelodysplastic...
Adult Acute Basophilic LeukemiaAdult Acute Eosinophilic Leukemia21 moreThis phase I/II trial is studying the side effects and best dose of tipifarnib when given with idarubicin and cytarabine and to see how well it works in treating patients with newly diagnosed myelodysplastic syndromes or acute myeloid leukemia. Drugs used in chemotherapy, such as idarubicin and cytarabine, work in different ways to stop cancer cells from dividing so they stop growing or die. Tipifarnib (Zarnestra) may stop the growth of cancer cells by blocking the enzymes necessary for their growth. Giving idarubicin and cytarabine with tipifarnib may kill more cancer cells.
Anti-Interleukin-5 Antibody to Treat Hypereosinophilic Syndrome
Hypereosinophilic SyndromeThis study will examine the safety and effectiveness of a single dose of anti-interleukin-5 antibody (SCH 55700) in reducing the number of eosinophils (a type of white blood cell) in patients with hypereosinophilic syndrome. Patients with this disease have too many eosinophils in the blood and in body tissues, which cause damage to the affected organs-most commonly the heart, nerves and skin. SCH 55700 is an antibody to interleukin 5-a hormone-like substance produced by white blood cells that plays a significant role in eosinophilia. SCH 55700 has lowered eosinophilia blood counts in patients with asthma and reduced the number of these cells in tissues of animals with asthma. Patients with hypereosinophilic syndrome 18 years of age and older who have not responded to standard therapy with steroids, interferon and hydroxyurea or cannot take these drugs may be eligible for this study. Candidates will be screened with a medical history, physical examination, eye examination, and blood tests. Depending on the patient's symptoms, other diagnostic tests may be done, including studies of the eyes, lungs, skin, nerves or heart. Skin biopsy and bronchoalveolar lavage may be included in the diagnostic evaluation. For the skin biopsy, a small area about 1/3 inch in diameter is numbed and a small core of skin is surgically removed for study under the microscope. Bronchoalveolar lavage involves inserting a catheter (flexible tube) into the lungs to instill saline (salt water) and obtain a tissue sample. This test will be done only if clinically necessary. Those enrolled in the study will be admitted to the NIH Clinical Center for a single dose of SCH 55700, injected into an arm vein. They will be monitored in the hospital for at least 72 hours for changes in eosinophil count and side effects of the injection. After discharge, laboratory tests will be done weekly for the first month, either at the Clinical Center or by the patient's local physician. Follow-up visits will then be scheduled monthly for 1 year or until the patient's eosinophil count returns to pre-treatment levels for 2 consecutive months. Follow-up visits will include a history, physical examination and blood tests, including studies on how immune cells and other substances in the blood activate or stimulate eosinophilia. A chest X-ray, electrocardiogram and pulmonary function tests will be done at 1, 3, 6 and 12 months to evaluate organ damage. Other tests may be done if medically indicated. Bone marrow biopsy and aspiration will be done before receiving SCH 55700 and one month after the injection to evaluate the effects of SCH 55700 on eosinophil production in the bone marrow. For this test, an area of skin and bone is numbed and a very sharp needle is used to withdraw a sample of the bone marrow. Leukapheresis will also be done before and 1 month after SCH 55700 treatment to obtain cells for studying the effect of SCH 55700 on eosinophil activation, function and survival. For this procedure, whole blood is collected through a needle in an arm vein. The blood circulates through a machine that separates it into its components. The white cells are then removed, and the rest of the blood is returned to the body, either through the same needle used to draw the blood or through a second needle placed in the other arm.
Efficacy of Imatinib Mesylate in Hypereosinophilic Syndromes
Hypereosinophilic SyndromeChronic Eosinophilic Leukemia1 moreThe study was performed to assess: 1) clinical activity of Imatinib in patients with HES, CEL and CIH; 2) correlation between Imatinib activity and specific disease subtype; 3) long-term outcome of HES, CEL and CIH patients treated with Imatinib; 4) safety and tolerability of Imatinib administration.
Bortezomib and Combination Chemotherapy in Treating Younger Patients With Recurrent, Refractory,...
Adult Acute Monoblastic Leukemia (M5a)Adult Acute Monocytic Leukemia (M5b)20 moreThis phase II trial is studying the side effects and best dose of bortezomib and to see how well it works when given together with combination chemotherapy in treating younger patients with recurrent, refractory, or secondary acute myeloid leukemia (AML). Bortezomib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as idarubicin, cytarabine, and etoposide, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) together with bortezomib may kill more cancer cells
Fludarabine Phosphate, Melphalan, Total-Body Irradiation, Donor Stem Cell Transplant in Treating...
Accelerated Phase Chronic Myelogenous LeukemiaAcute Myeloid Leukemia With Multilineage Dysplasia Following Myelodysplastic Syndrome100 moreThis clinical trial is studying how well giving fludarabine phosphate and melphalan together with total-body irradiation followed by donor stem cell transplant works in treating patients with hematologic cancer or bone marrow failure disorders. Giving low doses of chemotherapy and total-body irradiation before a donor peripheral blood stem cell transplant helps stop the growth of cancer cells or abnormal cells. It may also 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 or abnormal cells (graft-versus-tumor effect)
Dasatinib as Therapy for Myeloproliferative Disorders (MPDs)

Lenalidomide in Treating Older Patients With Acute Myeloid Leukemia
Adult Acute Basophilic LeukemiaAdult Acute Eosinophilic Leukemia15 moreThis phase II trial is studying how well lenalidomide works in treating older patients with acute myeloid leukemia with abnormal chromosome 5q. Biological therapies, such as lenalidomide, may stimulate the immune system in different ways and stop cancer cells from growing.
3-AP and Fludarabine in Treating Patients With Myeloproliferative Disorders, Chronic Myelomonocytic...
Accelerated Phase Chronic Myelogenous LeukemiaAtypical Chronic Myeloid Leukemia9 moreThis phase II trial is studying how well giving 3-AP together with fludarabine works in treating patients with myeloproliferative disorders (MPD), chronic myelomonocytic leukemia (CMML), or accelerated phase or blastic phase chronic myelogenous leukemia. Drugs used in chemotherapy, such as 3-AP and fludarabine, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. 3-AP may help fludarabine work better by making cancer cells more sensitive to the drug. 3-AP and fludarabine may also stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Giving 3-AP together with fludarabine may kill more cancer cells.
