NCT00162227
This study is being conducted to assess the safety and tolerability of an oral liquid solution of Sustiva for antiretroviral therapy-naive or therapy-experienced HIV-1 infected children between the ages 3-16 who are failing or intolerant of current antiretroviral regimen and who are unable to swallow Sustiva capsules.
NCT00389675
This is a double-blind, active-controlled, long-term study of a new experimental drug called darusentan. Darusentan in not currently approved by the United States Food and Drug Administration (FDA), which means that a doctor cannot prescribe this drug. The purpose of this study is to evaluate the long-term safety of darusentan (optimized dose) as compared to an active control, administered orally.
NCT00862459
The purpose of this study is to look at the safety (what are the side effects) and efficacy (how well does it work) of Gadavist when used for taking images of the brain and spine. The results of the MRI with Gadavist Injection will be compared to the results of MR images taken without contrast and with the results of the MR images taken with OptiMARK.
NCT00301990
RATIONALE: Monoclonal antibodies, such as bevacizumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Bevacizumab may also stop the growth of tumor cells by blocking blood flow to the tumor. Interleukin-2 may stimulate the white blood cells to kill tumor cells. Giving bevacizumab together with interleukin-2 may kill more tumor cells. PURPOSE: This phase II trial is studying how well giving bevacizumab together with interleukin-2 works in treating patients with metastatic kidney cancer.
NCT00069004
The purpose of this study is to assess the prevalence of metabolic and physical abnormalities in HIV infected (via mother-to-child transmission) and uninfected children and youth. Metabolism, body composition, bone density, and other factors will be assessed in relationship to participants' exposure to highly active antiretroviral therapy (HAART).
NCT00004025
RATIONALE: Vaccines made from a person's white blood cells combined with melanoma antigens may make the body build an immune response to tumor cells. Interleukin-2 may stimulate a person's white blood cells to kill melanoma cells. Combining vaccine therapy with interleukin-2 may be an effective treatment for stage III or stage IV melanoma. PURPOSE: Phase I/II trial to study the effectiveness of vaccine therapy with or without interleukin-2 in treating patients who have stage III or stage IV melanoma that cannot be surgically removed.
NCT01065051
The aim of this study is to assess whether oral Riociguat affects the left ventricular contractility and relaxation in patients with pulmonary hypertension associated with left ventricular systolic dysfunction
NCT00074984
People with Fabry disease have an alteration in their genetic material (DNA) which causes a deficiency of the a-galactosidase A enzyme. Fabrazyme (agalsidase beta) is a drug that helps to breakdown and remove certain types of fatty substances called "glycolipids." These glycolipids are normally present within the body in most cells. In Fabry disease, glycolipids build up in various tissues such as the liver, kidney, skin, and blood vessels because a-galactosidase A is not present, or is present in small quantities. The build up of glycolipid ("globotriaosylceramide" or "GL-3") levels in these tissues in particular is thought to cause the clinical symptoms that are common to Fabry disease. This study will test the safety and efficacy of Fabrazyme in the treatment of patients with Fabry disease.
NCT00525512
The objective of this study is to evaluate the effects on exercise duration of 96 weeks treatment with 18 mcg tiotropium (Spiriva HandiHaler) daily as compared to placebo, in patients with COPD.
NCT00023205
People with poor literacy may have worse health and less knowledge about how to manage their disease than patients at high reading levels. Patients with arthritis usually receive information on how to manage their disease that is written at an 11th grade reading level. The purpose of this study is to compare the health outcomes of patients with arthritis given either standard 11th grade level materials or interactive, in-person arthritis education along with materials written at a lower reading level.
NCT00132314
In the proposed study 450 veterans with a primary diagnosis of schizophrenia who had at least one psychiatric hospitalization for schizophrenia in the previous 2 years would be randomly assigned at 16 VA medical centers to long-acting injectable risperidone or doctor's choice of oral antipsychotic medication (i.e., excluding other long-acting injectable medications, but not specifying any particular oral agents or dosages). Recruitment would take 27 months to complete, and the study would continue for a third year to allow 9 months of follow-up for the last patient recruited. All patients would be treated from the time of entry up to the end of the three-year study period. Follow-up assessments would continue quarterly. Treatments would not be blinded since giving placebo injections to the comparison group would interfere with the goal of comparing the acceptability of two different methods of medication administration. However, end points will be blindly rated.
NCT00397969
RATIONALE: Receiving a reminder letter from their doctor may increase the frequency of colonoscopy in patients who have had a colorectal polyp removed. PURPOSE: This randomized clinical trial is studying how well a reminder letter from their doctor improves the frequency of colonoscopy in patients who have had a colorectal polyp removed.
NCT00012389
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 if irinotecan is more effective with or without oxaliplatin in treating metastatic colorectal cancer. PURPOSE: Randomized phase III trial to compare the effectiveness of irinotecan with or without oxaliplatin in treating patients who have metastatic colorectal cancer.
NCT00008281
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 which regimen of chemotherapy is more effective for metastatic colorectal cancer. PURPOSE: Phase III trial to compare the effectiveness of three chemotherapy regimens in treating patients who have metastatic colorectal cancer.
NCT01516151
To evaluate the efficacy of 0.5, 1.0, 2.0 and 4.0 g/ day of CaPre™ in reducing fasting plasma serum triglycerides over a four week period in patients with mild-to-high hypertriglyceridemia as compared to the standard of care alone.
NCT02028351
Purpose of The Study: The purpose of this study is the following: A)To gather age-related normative visual acuity data for the Vimetrics Central Vision Analyzer (CVA, Vimetrics, LLC, Media, Pa) B)To gather visual acuity data for patients with known ocular problems, including cataract and maculopathy. C)To correlate and compare the CVA visual acuity findings with the acuity measured with standard LogMAR acuity charts viewed under similar conditions of contrast and lighting
NCT00909259
The purpose of this feasibility study is to determine the effect of stimulating the phrenic nerve to treat periodic breathing (a pattern of breathing characterized by hyperpneas followed by hypopneas or apneas). Clinically, these physiologic events translate into sleep fragmentation, excessive daytime sleepiness, reduced exercise capacity, and possibly ventricular arrhythmias. Stage 1 of the study is acute in nature, such that subjects will undergo the placement of a stimulation lead, followed by assessment of stimulation of the phrenic nerve using the lead for up to 2 nights of sleep. A sensing lead may also be placed during the initial implant procedure. Observational data will be obtained and stimulation provided using an externalized system connected to the study leads. Following the study, all investigational components will be removed from the patient. Stage 2 of the study is being conducted at one of the participating sites to determine the initial safety of chronic stimulation of the phrenic nerve in a limited number of patients with sleep disordered breathing. It is anticipated that data obtained in this feasibility study will show that the proposed intervention can modify respiration with a low incidence of adverse effects. The results of this trial are intended to be used to develop a subsequent protocol for a multi-center study of chronic phrenic nerve pacing.
NCT01134393
The general aim of this trial to determine the efficacy as measured by the percentage of patients reaching blood pressure goal at the end of the treatment period at 12 weeks. In-clinic blood pressures, home blood pressures and safety will be carefully monitored.
