NCT00001941
The purpose of the study was to determine: (1) the toxicity and maximum tolerated dose (MTD) of humanized anti-Tac (daclizumab), (Zenapax(Registered Trademark)) in patients with adult T-cell leukemia/lymphoma (ATL); (2) to define the dose of Zenapax(Registered Trademark) required to saturate interleukin 2 receptor alpha (IL-2R) alpha in patients with ATL; (3) determine the clinical response to humanized (Hu) anti-Tac (Zenapax(Registered Trademark) of patients with Tac-expressing adult T-cell leukemia; and (4) determine the serum dieaway curve (pharmacokinetics) of infused humanized (Hu)-anti-Tac in patients who have ATL. This study represented an extension of Metabolism Branch National Cancer Institute (NCI) protocols utilizing modifications of the original murine anti-Tac monoclonal antibody (mAb) developed by our group for the treatment of ATL. The scientific basis for these therapeutic studies is that the leukemic cells of patients with ATL express abnormally high levels of the Tac antigen (IL-2R alpha) on their surface whereas resting normal cells including normal T-cells of the patients do not. One presumed mode of action of Hu-anti-Tac in the treatment of ATL involves the interruption of the interaction of interleukin 2 (IL-2) with its growth factor receptor. To be effective in this goal we must maintain saturation of the IL-2 receptors (IL-2R) with humanized anti-Tac thereby preventing IL-2 mediated proliferation and yielding cytokine deprivation and apoptotic cell death of the leukemic cells. Eligible patients with ATL were treated with escalating doses of Zenapax(Registered Trademark) between groups in the Clinical Center of the National Institutes of Health (NIH). Groups of patients received sufficient Zenapax(Registered Trademark) to yield saturation of the IL-2 receptor for a period of 17 weeks. Clinical response was evaluated using routine immunological and clinical evaluation and by monitoring the saturation of the IL-2R and the absolute number of residual circulating malignant cells by fluorescence activated cell sorting (FACS) analysis using two fluorochrome-labeled non-crossreacting antibodies to the IL-2 receptor, anti-Tac and 7G7/B6, as well as antibodies to cluster of differentiation 3 (CD3), cluster of differentiation 4 (CD4), cluster of differentiation 7 (CD7), and cluster of differentiation 8 (CD8). Furthermore, responses were evaluated in patients with leukemia by Southern blot analysis of the arrangement of the T-cell receptor genes and human T-lymphotropic virus type 1 (HTLV-I) integration. Finally, in select patients, to define the pharmacokinetics of the therapeutic antibody, had planned to monitor the serum levels of the infused Hu-anti-Tac (Zenapax(Registered Trademark)) as a function of time. This study is an essential element of our program involving IL-2R-directed therapeutic studies. If as anticipated the therapy with humanized anti-Tac yields some partial and complete remissions in patients with ATL, we will propose that it be used as a single agent for patients with smoldering and chronic ATL and in association with chemotherapeutic agents to provide a novel approach for the treatment of acute and lymphoma forms of ATL. We also plan a future clinical trial where tentative plans also had been made to evaluate the efficacy and toxicity in ATL patients of saturating doses of Zenapax(Registered Trademark) as compared to identical doses of Zenapax(Registered Trademark) given in association with (90)Y-armed 7G7/B6, a non-competing antibody to IL-2R alpha or in combination with chemotherapy.
NCT00445549
Background: * Vandetanib is a drug that attacks a group of proteins on the surface of many cells, especially blood vessel cells and tumor cells. * Tumors require the development of new blood vessels in order to grow and spread. * In laboratory experiments, vandetanib slowed the growth of certain tumors and regulated their blood vessel growth. * In early clinical trials, some patients' tumors did not grow for a period of time while they were receiving vandetanib. Objectives: * To determine whether vandetanib can cause tumors to shrink or stabilize in some patients with ovarian cancer, fallopian tube cancer or primary peritoneal cancer. * To determine, by tumor biopsy, if features of the tumor change with vandetanib treatment may predict if the tumor will likely respond to vandetanib. Eligibility: * Women 18 years of age and older with ovarian, fallopian tube or primary peritoneal cancer that does not respond to standard treatment. Design: * Patients take vandetanib daily, by mouth in 28-day cycles until their disease worsens or they develop unacceptable side effects. * Tumor biopsies (surgical removal of a sample of tumor tissue) are done before starting vandetanib treatment and after 6 weeks of treatment. * Patients are followed in the clinic every 4 weeks during treatment for a physical examination, blood tests, and review of laboratory studies and side effects. * Patients have a computed tomography (CT) scan every 8 weeks to monitor tumor growth and magnetic resonance imaging (MRI) before starting vandetanib treatment, on the third day after taking vandetanib and 6 weeks into treatment. * Patients quality of life is assessed with regularly scheduled questionnaires.

NCT00098891
Phase I trial to study the effectiveness of combining MS-275 with isotretinoin in treating patients who have metastatic or advanced solid tumors or lymphomas. MS-275 may stop the growth of cancer cells by blocking the enzymes necessary for their growth. Isotretinoin may help cancer cells develop into normal cells. MS-275 may increase the effectiveness of isotretinoin by making cancer cells more sensitive to the drug. MS-275 and isotretinoin may also stop the growth of solid tumors or lymphomas by stopping blood flow to the cancer. Combining MS-275 with isotretinoin may kill more cancer cells
NCT00012376
Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Colony-stimulating factors such as sargramostim may increase the number of immune cells found in bone marrow or peripheral blood and may help a person's immune system recover from the side effects of chemotherapy. Phase I trial to study the effectiveness of bryostatin 1 combined with sargramostim in treating patients who have refractory myeloid cancer
NCT00112853
This phase I trial is studying the side effects and best dose of tipifarnib and etoposide in treating older patients with newly diagnosed acute myeloid leukemia. Tipifarnib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as etoposide, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving tipifarnib together with etoposide may kill more cancer cells
NCT00003805
RATIONALE: Antibiotic therapy may prevent the development of infection in patients with hematologic cancer and the persistent fever caused by a low white blood cell count. It is not yet known which regimen of antibiotics is most effective in preventing infection in these patients. PURPOSE: Randomized phase III trial to study the effectiveness of piperacillin-tazobactam with or without vancomycin in reducing fever in patients who have leukemia, lymphoma, or Hodgkin's disease.
NCT00022555

The main purpose of this study are to determine the maximum dose of AT-406 that can be safely given in combination with cytarabine and daunorubicin to humans. Other purposes are to determine how the drug is broken down in the body, and to see if there are any molecular interactions that can help determine how AT-406 works. Side effects will also be studied in an effort to make sure that this drug is safe to take.
NCT00288275
Chemoresponse assays (lab test) measure the effect that chemotherapy treatment has on a patient's cancer cells in the lab. This test has shown success in a retrospective study in predicting how an individual patient's tumor will respond to a given chemotherapy and how treatment utilizing an agent that the test said that a patient's cells would be sensitive too corresponds to a longer progression free interval. This study will determine the ability of two tests used to predict the success of chemotherapy in recurrent, persistent, or refractory cancer of the ovaries, fallopian tube(s) or peritoneum by measuring how long patients live without progression.
NCT00777309
This is a randomized, placebo-controlled, double blind phase 2 study designed to compare treatment with ARQ 197 plus erlotinib to erlotinib plus placebo in patients with non-small cell lung cancer. The study will enroll patients who have had one prior chemotherapy regimen (other than erlotinib) for NSCLC.
NCT00004934
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. It is not yet known whether receiving paclitaxel and carboplatin with epirubicin is more effective than paclitaxel and carboplatin alone for ovarian epithelial, fallopian tube, or peritoneal cancer. PURPOSE: Randomized phase III trial to compare the effectiveness of paclitaxel and carboplatin with or without epirubicin in treating patients who have stage IIB, stage III, or stage IV invasive ovarian epithelial, fallopian tube, or peritoneal cancer.
NCT00060372
