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.
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.
NCT01285570
Post-operative administration of ulimorelin is expected to reduce time to recovery of Gastrointestinal (GI) function in patients who have undergone partial large bowel resection.
NCT01318876
Influenza vaccines are continuously modified to adjust to the virus antigenic shifts or drifts, and its safety profile may vary. While generally considered safe, influenza vaccines have been associated in the past with increases in cases of Guillain-Barré syndrome (1976) and with oculorespiratory syndrome in 2001. Last year, with the vaccination against the pH1N1, an increase of allergic-like reactions was observed. Passive surveillance is collecting notifications of adverse events (AE) on the whole population but the sensitivity of this system is not high and its timeliness is not necessarily optimal. Last year, with the new pandemic Influenza vaccine the investigators piloted a web-based active surveillance of a large number of health care workers (HCW) vaccinated with the new adjuvanted monovalent pH1N1 influenza vaccine (Arepanrix® GSK, Canada). Because healthcare workers (HCW) constituted a well-defined group with general good health and received the Influenza vaccine in priority, this group of people was well suited for monitoring the safety of the influenza vaccine. For this study, 6242 HCW were recruited in three different sites (5183 were from Quebec). A total of 468 events (local reactions, fever, systemic reactions, gastrointestinal and respiratory problems) were reported by 430 HCW. 80% of the HCW recruited completed at least one of the three surveys and 52% responded to all questionnaires. During this surveillance, the investigators didn't have unexpected findings but this active surveillance of adverse events among healthcare workers would have been effective enough to rapidly detect adverse events occurring at a rate ≥ 1 per 200 vaccinees. For this year the investigators want to expand the surveillance to more sites and more participants to be able to detect AE occurring at rates ≥ 1 per 500 vaccinees, and to increase the response rate to all three surveys in participants. The main objective of this project is to estimate in HCW vaccinated against influenza the frequency of adverse events of sufficient severity to cause work absenteeism or medical consultation. This year the network will include 5 Canadian hospitals (Quebec City, Vancouver, Toronto, Halifax, + another one ) with a total enrollment of \>10 000 HCW. This should allow us to detect AE occurring at a rate of ≥ 1 per 500 vaccinees.
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.
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.
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.
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.
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.
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.
