NCT00046241

NCT00985023
The Lisfranc ligaments are a group of ligaments that connect the bones of the middle portion of the foot to each other. The Lisfranc ligaments allow for a normal and stable range of motion and shape to the foot. In certain foot fractures where the Lisfranc ligaments are damaged, the constraint and stability it had given to the middle of the foot is lost. Attempted activity at the foot will result in pain and abnormal motion. If injury to the Lisfranc ligaments is left untreated, the eventual end result is foot arthritis and deformity. The current standard orthopaedic treatment of foot fractures with Lisfranc ligament injuries is surgery. The foot fractures are fixed with metal screws. The Lisfranc ligaments are fixed by compressing the space between the middle bones of the foot with steel screws. These screws allow for ligament healing. As the ligaments heal, the patient should not resume activity with the fixed foot too soon as the screw may break. Upon breakage, the ligament repair may fail and the screw is now difficult to surgically remove. Regardless of breakage, a second surgical procedure is often recommended to remove the steel screw 6 months after foot surgery. This allows for a complete return of normal foot range of motion, but at the cost of a second surgical procedure. The investigators hypothesize that absorbable screw fixation of the Lisfranc ligaments does not yield significant differences in postoperative foot stability, ligament function, and symptoms when compared to steel screw fixation. In addition, absorbable screw fixation of the Lisfranc ligaments offers the advantage that a second surgical procedure to remove the screw is not necessary.
NCT00197288
The purpose of this study is to compare two licensed influenza vaccines (Fluzone and Fluarix) in terms of the immune response elicited and the safety/ any symptoms that may occur for up to six months after vaccination.
NCT01808131
This study will assess the serum uric acid lowering effects and safety of lesinurad in combination with allopurinol over a long-term timeframe.
NCT00108914
The purpose of this study is to determine if the investigational drug is effective and safe in children with perennial allergic rhinitis.
NCT02107196
Irritable Bowel Syndrome with diarrhoea (IBS-D) is a functional gastrointestinal disorder characterised by chronic or recurrent abdominal pain or discomfort and diarrhoea. This trial aims at the evaluation of the efficacy and safety of oral ibodutant 10 mg once daily as compared to placebo in women with IBS-D over a 12-week treatment period.
NCT00358358
This study will last for approximately 14 weeks and will involve 5 visits. The study is being carried out to look at different ways of measuring the effect of drug treatment on COPD. COPD is a respiratory disease which can affect your breathing and daily life. Symptoms of COPD can include breathlessness, cough, and wheeze. COPD varies enormously from patient to patient. The effects of drug treatment are usually measured by conducting lung function tests (breathing tests) using a machine called a spirometer but this does not always provide a complete picture of how well your COPD is responding. In this study we therefore want to look at new and more sensitive ways of measuring COPD. The results of this research will help in the assessment of new drugs for COPD in the future.
NCT00108095
This study is looking at a range of doses of this NK-1 receptor antagonist drug, for both safety and effectiveness in prevention PONV
NCT00004867
RATIONALE: Imaging procedures such as positron emission tomography may improve the ability to determine the stage of esophageal cancer. PURPOSE: This clinical trial is studying how well fludeoxyglucose F 18 positron emission tomography determines tumor stage in patients with esophageal cancer.
NCT00003966
RATIONALE: Giving defibrotide may be an effective treatment for liver damage that may result following peripheral stem cell transplantation. PURPOSE: This randomized phase II trial is studying defibrotide to see how well it works in treating patients with severe liver disease after undergoing peripheral stem cell transplantation.
NCT00036478
The purpose of this study is to see if magnetic resonance spectroscopy (MRS) can be used to detect damage to the mitochondria in HIV-infected patients taking nucleoside reverse transcriptase inhibitor (NRTI) drugs. HIV-infected patients taking NRTI drugs may have an increase in a chemical in their blood called lactate. High lactate levels may damage the energy source of the cell (mitochondria). Damage to mitochondria may cause lactic acidosis, liver failure, and other problems. It is important to find effective ways to see if the mitochondria of HIV-infected patients have been damaged. This study will see if MRS can be used to determine mitochondrial damage.
NCT02074007
Children ages 2 months to less than 19 years old, who have been diagnosed with a middle ear infection may receive either medicated ear drops (AR01) or glycerin (placebo) ear drops. The patient or caregiver will measure the amount of ear pain before and after the ear drops to establish if the medicated ear drops decrease the amount of pain more than the placebo ear drops. The subject may leave the clinic 60 minutes after the first dose. The ear drops can be used up to 4 days, as needed for ear pain.
NCT01683695
This is a multicenter, randomized, double-blind, parallel, placebo-controlled, multiple dose study that will enroll approximately 40 systemic lupus erythematosus subjects with active lupus arthritis.
NCT01484002
This retrospective study will investigate the changes that occur in ultrahigh molecular weight polyethylene (UHMWPE) implants that have been retrieved from joint replacement patients. Analysis techniques will include Fourier Transform Infrared Spectroscopy (FTIR), Differential Scanning Calorimeter (DSC) and crosslink density measurements. Crosslink density measurements will be evaluated as a function of distance away from the articular surface and the rim of the implant. Gel and hydroperoxide contents will also be evaluated. The objective is to characterize the in vivo and ex vivo changes that occur with cross-linked and conventional polyethylene bearings sterilized by methods that do not involve radiation. The investigators hypothesize that polyethylene absorbs lipids in vivo but experiences negligible oxidation or reductions in polymer crosslinking until it is explanted and stored at room temperature with access to ambient air.
NCT02100475
This trial is conducted globally. The aim of the trial is to compare sequential addition of insulin aspart versus further dose increase with insulin degludec/liraglutide in subjects with type 2 diabetes mellitus, previously treated with insulin degludec/liraglutide and metformin and in need of further intensification. This is an extension to trial NN9068-3952, NCT01952145 (DUAL™ V).
NCT00787033
Phase 1 safety, pharmacokinetics, and pharmacodynamics trial of the focal adhesion kinase (FAK) inhibitor PF-04554878 in patients with advanced non-hematologic malignancies, including patients with malignancies appropriate for serial biopsy. Screening consists of medical history, physical examination ECOG performance status, blood draws, a pregnancy test for female patients of childbearing potential, a FDG-PET and tumor imaging. Treatment consists of PF-04554878 pills continued until progression of disease, unacceptable toxicity, or patient request. Evaluations for bioactivity are measured by serial FDG-PET and blood tests for biomarkers related to FAK and Pyk2 activities.
NCT01557348
This multicenter, prospective, observational study will assess the efficacy of MabThera/Rituxan (rituximab) and alternative TNF-inhibitors in patients with rheumatoid arthritis who are non-responders or intolerant to a single previous TNF-inhibitor. Data will be collected from each patient from the time of change in biologic therapy for 12 months.
