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.
NCT00794586
The purpose of this study is to evaluate the safety and efficacy of 2 dose combinations of fosfomycin/tobramycin for inhalation (FTI), following a 28-day course of Aztreonam for Inhalation (AZLI) in patients with cystic fibrosis and Pseudomonas aeruginosa lung infection.
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.
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.
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.
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.
NCT00003917
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 topotecan is more effective given by infusion or by mouth. PURPOSE: Randomized phase III trial to compare the effectiveness of topotecan given by infusion with that of topotecan given by mouth in treating patients who have small cell lung cancer that has relapsed following previous therapy.
NCT00845091
The current research study proposes to examine participants with implantable cardioverter defibrillators (ICD) who are randomly assigned to either an exercise training program intervention or a heart healthy education program intervention. We will look at changes in the functioning of the autonomic nervous system over time and between intervention groups. We are also going to be looking at changes in frequencies of the ICD participants' heart arrhythmias and ICD therapies (e.g., pacing, shock).; as well as, changes in exercise tolerance, psychological well-being, and quality of life.
NCT00961051
The purpose of this study is to evaluate the safety and effectiveness of an investigational multi-purpose contact lens solution.
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.

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
NCT00530842
The primary objective of this study is to demonstrate that treatment with a free combination of tiotropium and salmeterol provides superior improvement in static lung volumes and exercise tolerance compared to a fixed combination of fluticasone and salmeterol in patients with COPD. The secondary objective includes assessment of safety.
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.
