Filter by:This phase I trial is studying the side effects and best dose of flavopiridol in treating patients with relapsed or refractory acute myeloid leukemia, acute lymphoblastic leukemia, or chronic myelogenous leukemia. Drugs used in chemotherapy, such as flavopiridol, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing.
This phase I trial is studying the side effects and best dose of tanespimycin when given with cytarabine in treating patients with relapsed or refractory acute myeloid leukemia, acute lymphoblastic leukemia, chronic myelogenous leukemia, chronic myelomonocytic leukemia, or myelodysplastic syndromes. Drugs used in chemotherapy, such as tanespimycin and cytarabine, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Tanespimycin may also help cytarabine kill more cancer cells by making cancer cells more sensitive to the drug. Giving tanespimycin together with cytarabine may kill more cancer cells.
This is an open label study of mepolizumab 750 mg intravenous in those subjects who participated in study 100185 to evaluate the long term safety and efficacy of mepolizumab in subjects with hypereosinophilic syndrome. The study will also evaluate the optimal dosing frequency for clinical use, the effects on corticosteroid reduction, and decrease of signs and symptoms of Hypereosinophilic Syndrome.
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. Bevacizumab may stop the growth of cancer by stopping blood flow to the leukemic cells in the bone marrow. Giving idarubicin and cytarabine with bevacizumab may kill more cancer cells. It is not yet know whether giving idarubicin together with cytarabine is more effective with or without bevacizumab in treating acute myeloid leukemia. This randomized phase II trial is studying how well giving idarubicin and cytarabine together with bevacizumab works compared to idarubicin and cytarabine alone in treating patients with newly diagnosed acute myeloid leukemia
This 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.
Phase I trial to study the effectiveness of XK469R in treating patients who have refractory hematologic cancer. Drugs used in chemotherapy, such XK469R, work in different ways to stop cancer cells from dividing so they stop growing or die
Eosinophils are a type of white blood cell. Elevated eosinophil levels can damage the heart, nerves, and other organs, in the syndrome known as hypereosinophilic syndrome (HES). Some individuals have a hereditary form of HES known as familial eosinophilia (FE). More research on the causation and mechanisms of HES is needed in order to design more effective and less toxic therapies. This study will investigate FE and its genetic causes, damage mechanisms, and disease markers (such as blood test abnormalities). It will enroll approximately 50 individuals (both adults and children) from a previously studied family with FE. This is a long-term study of indefinite duration. Participants will undergo yearly clinical examinations including medical history, physical examination, bloodwork, EKG, echocardiogram, and pulmonary function tests, with additional or more frequent examinations and tests as required. In addition, participants will donate blood and tissue for research purposes. Both adult and child participants will donate blood. At the initial evaluation, adult participants will donate bone marrow. During the study, some adult participants will also undergo a limited number of leukaopheresis sessions, in which blood is donated from one arm, the blood is separated into red blood cells and other components, and the red blood cells are returned into the donor's other arm.
This randomized phase II trial is studying how well cilengitide works in treating patients with acute myeloid leukemia. Cilengitide may stop the growth of cancer cells by blocking the enzymes necessary for their growth
Hypereosinophilic syndrome (HES) is a rare disease with broad clinical signs and symptoms which is diagnosed based on a persistent blood eosinophil count of greater than 1500 cells, various end-organ damages (including skin, heart, lung, nervous system and digestive system etc.), and with exclusion of known secondary causes of hypereosinophilia. HES has a high morbidity/mortality rate. The major treatment of HES has been systemic corticosteroid and other chemotherapeutic drugs (for example, hydroxyurea and interferon) with the intention to lower eosinophil counts and therefore to slow down the progression of disease. Even though corticosteroid and other therapies can effectively reduce eosinophilia in some patients, some may eventually become nonresponsive and intolerable to the amount of side effects of the long-term therapy with these medications. Mepolizumab is a humanized monoclonal antibody that binds specifically to human interleukin 5 (hIL-5) and inhibits its activity. Previous human experience has shown it has been effective in reducing blood eosinophilia in atopic and HES patients and has alleviated some HES clinical signs and symptoms. This study intends to further evaluate the corticosteroid-sparing and clinical benefit of mepolizumab in HES.
The purpose of this study is to evaluate the safety and efficacy of the tyrosine kinase inhibitor, imatinib mesylate (Gleevec ) in reducing peripheral blood eosinophilia in patients with the myeloid form of hypereosinophilic syndrome (HES). Patients with the hypereosinophilic syndrome who meet a set of criteria designed to select patients with the myeloid form of the disease, as well as patients without myeloid disease who are refractory to standard therapy for HES, will be admitted on this protocol. A thorough clinical evaluation will be performed with emphasis on potential sequelae of eosinophil-mediated tissue damage. A baseline bone marrow will be obtained to exclude leukemia or lymphoma and to assess the degree and nature of eosinophilopoiesis. Bone marrow, blood cells and/or serum will also be collected to test for the presence of a recently described mutation that is associated with imatinib-responsiveness in HES, and to provide reagents (such as DNA, RNA, and specific antibodies) and for use in the laboratory to address issues related to the mechanism of action of imatinib mesylate in HES. Imatinib mesylate will be initiated at a dose of 400 mg daily, the FDA-approved dose for the treatment of chronic myelogenous leukemia. In patients who demonstrate a complete clinical and hematologic response to imatinib therapy and who do not have life-threatening disease, the dose will be decreased gradually to 100mg daily and then discontinued. In order to minimize bone marrow suppression, other myelosuppressive agents will be tapered and discontinued during the first week of therapy with imatinib mesylate. Complete blood counts will be performed weekly for the first month and biweekly thereafter. Clinical assessments will be performed every three months to assess progression of end organ damage. In patients who demonstrate a complete clinical and hematologic response to imatinib therapy and who do not have life-threatening disease, the dose will be decreased gradually to 100 mg daily and then discontinued. In the event of clinical, hematologic or molecular relapse during the taper, the imatinib dose will be increased to a maximum of 600 mg daily to achieve a second remission. Laboratory monitoring will be performed as above except for molecular monitoring which will be monitored monthly if drug is discontinued or molecular relapse occurs. Once a stable dosing regimen is achieved for greater than or equal to 6 months in subjects who have undergone dose descalation or greater than or equal to 2 years in subjects receiving 300-400 mg of imatinib daily who did not qualify for dose de-escalation, the frequency of NIH visits and end organ assessments will be decreased to 6 months, with molecular monitoring every 3 months and monthly routine laboratory assessments. ...
