NCT00976027
The aim of this study is to determine the efficacy of Fluzone High Dose vaccine and that of Fluzone® vaccine in the elderly. Primary objective: To measure the efficacy of the vaccine, defined as the prevention of laboratory-confirmed influenza caused by viral types/subtypes that are antigenically similar to those contained in the respective annual vaccine formulations. Secondary objectives: * To compare the clinical efficacy of Fluzone High Dose vaccine with that of Fluzone® vaccine in elderly adults, with respect to laboratory-confirmed influenza illness caused by any type or subtype of influenza virus. * To compare the clinical efficacy of Fluzone High Dose vaccine with that of Fluzone® vaccine in elderly adults, in preventing culture-confirmed influenza illness caused by viral types/subtypes antigenically similar to those contained in the respective annual vaccine formulations.
NCT00421642
This is an open-label study of 20 patients designed to demonstrate the safety, tolerability and preliminary evidence of benefit of adalimumab in the treatment of subjects with Ulcerative Colitis, both in patients who have never received anit-TNF agents and in those who have lost response or developed intolerance to previous infliximab therapy.
NCT01475760
The purpose of this study is to determine the efficacy of chitosan chewing gum (K2CG) in reducing serum phosphorus in subjects with chronic kidney disease.
NCT01045187
Multicenter, non-randomized, feasibility study to evaluate the treatment and assess acute safety of the FDA Cleared Axxent Electronic Brachytherapy System and vaginal applicator for intracavitary vaginal cuff treatment according to the physician's current standard of care.
NCT01094340
This is a 24-week, randomized, double-blind, placebo-controlled study of the effect of thalidomide and placebo on CSF (cerebral spinal fluid) and plasma biomarkers in patients with mild to moderate Alzheimer's disease. This study will evaluate the effects of 24 weeks of treatment with Thalidomide on plasma biomarkers.
NCT00087490
To determine if linezolid is superior to vancomycin in the treatment of complicated skin and soft tissue infections due to MRSA in adult subjects
NCT00282711
The purpose of this study is to compare two types of exercise stress testing to find the best method for detecting heart disease in women.
NCT01519492
The purpose of the study is to determine the safety, tolerability and effectiveness of AFN-12520000 for in the treatment of Staphylococcal infections of the skin.
NCT00534313
The purpose of this study is to determine an optimal abatacept dosing regimen for the treatment of active arthritis due to psoriatic arthritis in patients who have had a prior inadequate response to disease-modifying antirheumatic drugs, including methotrexate and tumor necrosis factor alpha-blockade compounds.
NCT00354159
The purpose of this clinical research study is to evaluate the safety and effectiveness of the investigational implantable hemodynamic monitor (IHM), and of the IHM in combination with an implantable cardioverter defibrillator (ICD). The investigational IHM has the ability to record and report the force with which the heart pumps blood (heart pressures). When combined with the ICD, the device has the additional ability to send a strong electrical impulse, or shock, to the heart when it detects dangerously fast heartbeats to return it to a normal rhythm. The IHM and IHM/ICD are implanted surgically just under the skin in the upper chest area. This study will also determine how doctors use the information related to heart pressures in the management of heart failure.
NCT00085839
The purpose of this noncomparative study is to obtain preliminary estimates of the efficacy of erlotinib and standard chemotherapy in patients with advanced, previously untreated nonsmall cell lung cancer (NSCLC) and an Eastern Cooperative Oncology Group (ECOG) performance status (PS) of 2. The study will also evaluate the safety of single-agent erlotinib in this patient population.
NCT00752791
The purpose of this study is to determine the efficacy and safety of peginesatide injection for maintenance treatment of anemia in participants on peritoneal dialysis.
NCT00949975
The primary objective is to evaluate the dose-response relationship and efficacy of AZD9668 at 3 dose levels compared with placebo in symptomatic COPD patients by assessing effects on lung function and symptoms of COPD.
NCT00300274
This trial was to examine the impact of everolimus and reduced dose of cyclosporine on efficacy and safety compared to mycophenolate mofetil and a standard dose of cyclosporine in heart transplant recipients.
NCT00004861
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug or giving drugs in different ways may kill more tumor cells. PURPOSE: Randomized phase II trial to compare the effectiveness of gemcitabine with or without CI-994 in treating patients who have advanced pancreatic cancer.
NCT01188837
Common medical therapies for knee osteoarthritis are patient education, drug and physical therapy, exercise and surgery. These modalities may offer improvement but drugs and surgery carry significant risk. Manipulative therapy for KOA gives pain relief and increased function. However, research suggests addition of manipulative and soft tissue therapy (to the entire kinetic chain: lumbosacral, sacroiliac, hip, knee, ankle and foot joints), may give a better outcome. Exercise therapy is considered an effective and standard care for KOA.
NCT00690716
The purpose of this study is to evaluate the safety and effect of nasal carbon dioxide in the treatment of mild headaches in people who have migraines.
NCT00084903
RATIONALE: New diagnostic procedures such as fluorescence and reflectance spectroscopy (shining light on tissue and measuring patterns of light reflected) may improve the ability to noninvasively detect cervical intraepithelial neoplasia and dysplasia. PURPOSE: This diagnostic trial is studying how well fluorescence and reflectance spectroscopy during colposcopy work in detecting cervical intraepithelial neoplasia and dysplasia in healthy participants with a history of normal Pap smears.
NCT00511615
The hypothesis of this research project is that topical application of the anti-EGFR or anti-E6/E7 contrast agents followed by optical imaging will yield images that reflect spatial variations in expression that correlate with the presence of cervical precancer. To gather feasibility data the investigators will: 1. Obtain cervical specimens from women with high grade squamous intraepithelial lesions (HGSILs) being treated with the loop electrosurgical excision procedure (LEEP). 2. After Loop Electrosurgical Excision Procedure (LEEP) is performed, obtain low and high resolution optical images before and after applying contrast agents topically to the epithelial surface of the tissue for 30 minutes before rinsing. 3. Submit the specimen for histology, and have it sectioned and stained using both H\&E and immunohistochemical staining for EGFR or E6/E7. The images will be reconstructed into a two dimensional map delineating areas of Cervical Intraepithelial Neoplasia (CIN) and of EGFR or E6/E7 overexpression. Maps of the pathology will be compared to those obtained from the intact cervix exposed to the contrast agent.
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.
