There are about 28871 clinical studies being (or have been) conducted in Canada. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
This study will evaluate the antiviral efficacy, safety, and tolerability of ledipasvir/sofosbuvir (LDV/SOF) fixed-dose combination (FDC) administered for 12 weeks in hepatitis C virus (HCV) treatment-naive and treatment-experienced (including treatment intolerant) participants with chronic genotype 1 or 4 HCV infection who are co-infected with HIV-1. Participants who experience confirmed post-treatment virologic failure (relapse) at or before Posttreatment Week 24 may be eligible to be enrolled in the Retreatment Substudy to receive LDV/SOF plus ribavirin (RBV) for 24 weeks.
The objectives of this study are to evaluate the efficacy, safety, pharmacodynamic, pharmacokinetic and immunogenic profiles of satralizumab in participants with NMO and NMOSD.
The primary purpose of the study was to compare the macular hole closure and visual acuity gain following vitrectomy using SF6 gas tamponade with 7 days of face-down positioning versus C3F8 gas tamponade with 14 days of face-down positioning. The secondary purpose was to report, in each group, the cumulative incidence of cataract development 1 year following macular hole surgery and the proportion of complications (*). ((*) hypertony, hypotony, retinal tear, retinal detachment and endophthalmitis) This prospective randomized study examined a 3 year period. The first patient was included in January 2010 and the last in November 2011. The 12-month follow-up spread out from March 2011 to December 2012. The first group included 31 patients who had undergone macular hole surgery using SF6 gas and who were advised to stay in face-down position for 7 days postoperatively (SF6 group). These patients were compared to 28 patients who had undergone macular hole surgery with C3F8 gas and who were advised to maintain a face-down position for 14 days. Patients in both groups underwent vitrectomy, internal limiting membrane peeling, and fluid-gas exchange using either SF6 or C3F8. Preoperative data included the characterization of the hole with Optical Coherence Tomography (OCT), the best correct visual acuity (VA) recorded in number of letters using the Early Treatment Diabetic Retinopathy Study (ETDRS) chart, classification of the cataract according to the LOCS III and the intraocular pressure IOP. Postoperative data included OCT confirmation of the closure at 6 weeks and 1 year, 1 year's best corrected VA recorded in number of letters (EDTRS chart) and determination of cataract development and extraction as needed.
The purpose of this study is to determine whether a dietary supplement (DS) is effective in protecting against sad mood in postpartum.
The purpose of this study is to collect serum samples for use as quality control samples in GSK assays. The serum samples need to include samples with low, medium and high antibody titers/concentrations, which cover the assay range.
The objectives of this study were to characterize the effects of food on the pharmacokinetics (PK) and tolerability of BIA 9-1067 in healthy male subjects.
Patients with symptomatic atrial fibrillation (AF), a rapid beating of the upper heart chambers, can undergo catheter ablation to control or eliminate their rhythm disorder. The radiopharmceutical 123I-mIBG (Adreview™ GE Healthcare) has been introduced to visually identify cardiac innervation. This study will use non-invasive evaluation using MIBG imaging to study if we can predict baseline autonomic characteristics in patients with AF, as well as clinical outcome based on post ablation imaging
The purpose of the study is to evaluate whether remote ischemic conditioning is a safe and effective intervention to prevent the development of inflammation and coagulopathy in trauma patients with hemorrhagic shock.
Mechanical ventilation (MV) is a cornerstone of management of acute respiratory failure, but MV per se can provoke ventilator-induced lung injury (VILI), especially in acute respiratory distress syndrome (ARDS). Lung protective ventilation strategy has been proved to prevent VILI by using low tidal volume of 6-8 ml/kg of ideal body weight and limiting plateau pressure to less than 30 cmH2O. However, heavy sedation or even paralysis are frequently used to ensure the protective ventilation strategy, both of which are associated with respiratory muscles weakness. Maintaining of spontaneous breathing may decrease the need of sedative drug and improve gas exchange by promoting lung recruitment. Pressure-targeted mode is the most frequent way of delivering after 48 hours of initiating MV. Three types of pressure-controlled mode are available in intubated patients: Biphasic Intermittent Positive Airway Pressure (BIPAP), Airway Pressure Release Ventilation (APRV), and Pressure-Assist Controlled Ventilation (also called BIPAPassist). They are based on pressure regulation but have the difference in terms of synchronization between the patient and the ventilator. The different working principle of these modes may result in different breathing pattern and consequently different in tidal volume and transpulmonary pressure, which may be potentially harmful. The investigators bench study with a lung model demonstrated higher tidal volume and transpulmonary pressure with the BIPAPassist over APRV despite similar pressure settings and patient's simulated effort. However, the impact of each mode on the delivered tidal volume and the transpulmonary pressure in spontaneously breathing mechanically ventilated patients is currently unknown. Their hypothesis is that when the investigators compare the three pressure-controlled modes, the asynchronous mode (APRV) will result in more protective ventilation strategy over the two other modes (BIPAP and BIPAPassist).
Understanding of an operation and its risks has been shown to give patients more realistic expectations, increase cooperation and result in higher satisfaction. Traditionally, informed consent for surgical procedures involve a discussion between the surgeon and the patient, but many patients easily forget the details of these talks. The investigators wish to investigate if providing a written pamphlet along with the standard oral discussion improves patients' ability to remember the details of the operation, improving the quality of the informed consent process. In addition, we will test whether a group consultation format provides a model for large-volume, low-variation, low-urgency surgery without reducing ability to recall risks of surgery or overall satisfaction.
