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.
NCT00030992
This study will examine whether the experimental drug BMS 247550 (Ixabepilone) is an effective treatment for kidney cancer. BMS 247550 belongs to a class of drugs called epothilones that interfere with the ability of cancer cells to divide. In the way they kill cells, they are very similar to a class of compounds known as the taxanes, which include the drug Taxol. Other characteristics of the epothilones, however, enable them to work in cells that are resistant to Taxol. Patients 18 years of age or older with kidney cancer that has not spread to the central nervous system (unless the brain tumor has remained stable for at least six months after surgical or radiation treatment) may be eligible for this study. Pregnant or nursing women may not participate. Candidates are screened with various tests that may include blood and urine tests, electrocardiogram (EKG), and chest x-ray. Computerized tomography (CT) scans or X-rays, and possibly nuclear medicine studies may be done to determine the extent of disease. Participants receive BMS 247550 by a 1-hour infusion into a vein for 5 consecutive days (days 1, 2, 3, 4 and 5) of each 21-day treatment cycle. Patients must stay in the National Institutes of Health (NIH) area near Bethesda, Maryland, for 7 to 8 days during the first treatment cycle and for the 5 days of treatment in subsequent cycles. The total number of cycles will vary among patients, depending on their individual clinical situation. The drug dose may be increased gradually in subsequent cycles in patients who can tolerate such increases. In addition, participants undergo the following tests and procedures: * Periodic physical examinations and frequent blood tests * X-ray and other imaging studies to determine if the tumor is responding to the treatment. * Tumor biopsies to confirm the diagnosis or spread of tumor and to examine the reaction of certain proteins in cancer cells to BMS 247550. Two biopsies will be done. For this procedure, a small piece of tumor tissue is withdrawn through a needle under local anesthetic. Treatment will be stopped in patients whose tumor grows while receiving BMS 247550. Patients whose tumor disappears completely will be followed at NIH periodically for examinations and tests. Patients whose disease does not completely resolve or whose disease recurs may be advised of other appropriate research protocols at NIH or, if none are available, will be returned to the care of their local doctor.
NCT00450970
The SPERA trial is designed to 1. provide satraplatin to physicians with patients who have hormone refractory prostate cancer (HRPC) which has progressed following unlimited cytotoxic chemotherapy regimens for metastatic disease and 2. to evaluate the safety of oral satraplatin in this patient population.

NCT00909727
The purpose of this study was to evaluate the efficacy and safety of ivacaftor in subjects with cystic fibrosis aged 6 to 11 years who have the G551D mutation in the cystic fibrosis transmembrane conductance regulator (CFTR) gene. Ivacaftor is a potent and selective potentiator of wild-type, G551D, F508del, and R117H forms of human CFTR protein. Potentiators are pharmacological agents that increase the chloride ion transport properties of the channel in the presence of cyclic adenosine monophosphate (AMP)-dependent protein kinase A (PKA) activation.

NCT00110513
Patients with hereditary antithrombin deficiency are at increased risk of venous thrombosis and pulmonary embolism, particularly during certain high risk procedures. The trial focused on patients with confirmed hereditary antithrombin deficiency who were undergoing a surgical procedure or induced/spontaneous labor and delivery, and/or caesarean section. The study assessed the incidence of thromboembolic events following prophylactic intravenous administration of recombinant human antithrombin (rhAT) to patients with hereditary antithrombin (AT) deficiency in situations usually associated with a high risk for thromboembolic events.
NCT00104988
RATIONALE: Thalidomide may stop the growth of melanoma by blocking blood flow to the tumor. It may also stimulate the immune system in different ways and stop tumor cells from growing. Drugs used in chemotherapy, such as temozolomide, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving thalidomide together with temozolomide may kill more tumor cells. PURPOSE: This phase II trial is studying how well giving thalidomide together with temozolomide works in treating patients with stage IV melanoma that cannot be removed by surgery.

NCT01584050
Folic acid, a form of the vitamin folate, is added to grain products in Canada to help reduce birth defects. Folic acid is the synthetic form of folate and is very stable (doesn't break down) when added to foods. There are emerging health concerns about chronic folic acid consumption. Recently another more natural form of folate, L-5-methyltetrahydrofolate (L-MTHF) has become available. The investigators plan to conduct a randomized trial in women to determine if supplements containing L-MTHF consumed over three months raises blood folate levels as much as supplements containing folic acid. The investigators hypothesize that L-MTHF will increase red cell folate over 12 weeks to same extent as equimolar folic acid.
