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.
The purpose of this study is to assess the effectiveness of the PleuraFlow® Active Tube Clearance (ATC) technology in reducing the rate of postoperative atrial fibrillation (POAF) among post cardiac surgery patients and to evaluate the impact of Active Tube Clearance (ATC) on other complications, such as retained blood syndrome (RBS), a composite endpoint including re-exploration for bleeding or tamponade, and interventions for hemothorax, pericardial or pleural effusion.
The investigators have developed an assay that can sensitively and specifically detect DNA mutations circulating in human plasma that may be indicators of the presence of a solid tumor. This study is a pilot study to measure positive and negative predictive values of this assay as an indicator of the presence of a tumor in normal subjects
The purpose of this study is to to assess the safety and tolerability of pirfenidone 2403 mg/day for the treatment of RA-associated interstitial lung disease.
The purpose of this study is to continue to characterize the safety profile of benralizumab administration and monitor the pharmacodynamic activity of the drug in those asthma patients who remain on treatment for at least 16 weeks and not more than 40 weeks in the predecessor study D3250C00021 (BORA, NCT02258542).
Lipotoxicity-causing fatty acid overexposure and accretion in lean tissues leads to insulin resistance and impaired pancreatic β-cell function - the hallmarks of T2D - contributing to associated complications such as heart failure, kidney failure and microvascular diseases. Proper dietary fatty acid (DFA) storage in white adipose tissue (WAT) is now thought to prevent lean-tissue lipotoxicity. Using novel Positron-Emission Tomography (PET) and stable isotopic tracer methods which were developed in Sherbrooke, the investigator showed that WAT storage of DFA is impaired in people with pre-diabetes or T2D. The investigator also showed that this impairment is associated with greater cardiac DFA uptake, as well as subclinical left-ventricular systolic and diastolic dysfunction. Then, It has been found that modest weight loss in pre-diabetics, after a one-year lifestyle intervention, improved WAT DFA storage, curbed cardiac DFA uptake, and restored associated left-ventricular dysfunction. It has been also found that a 7-day low-saturated fat, low-calorie diet raised insulin sensitivity but did not restore WAT or cardiac DFA metabolism. Whether WAT DFA storage directly impacts cardiac DFA uptake is not known. Importantly, the investigator recently uncovered marked sex-specific differences in WAT DFA metabolism. These may explain, at least in part, sex-related differences in the cardiac DFA uptake, which occurs in pre-diabetes. Higher spillover of WAT DFA into circulating Non-Esterified Fatty Acid (NEFA) appears to be linked in women to greater cardiac DFA uptake, as opposed to direct cardiac chylomicron triglycerides (TG) uptake in men. Here, the investigator will isolate and compare organ-specific fatty acid uptake occurring postprandially from chylomicron-TG vs. NEFA pools, as well as the oxidative vs. non-oxidative intracellular metabolic pathways associated with increased cardiac DFA uptake in pre-diabetic men and women.
A Phase III, randomised study of atezolizumab alone and in combination with chemotherapy versus chemotherapy alone in participants with untreated advanced urothelial cancer.
This Phase 2a, pharmacokinetic/pharmacodynamic study will determine the safety and provide evaluation of the PK/PD metrics of three different oral doses selected upon the results of the study LOPDT-PH1-01 - 4 mg oral tablets administered over 28 days as QD and BID regimens and 10 mg oral tablets administered over 28 days as a BID regimen. The PK/PD profiles of the study drug will be compared to the leuprolide formulation approved for the treatment of endometriosis (a monthly intramuscular injection, Lupron Depot 3.75 mg). Major PK (e.g., a total exposure to leuprolide) and PD parameters (e.g., rates of the estradiol suppression and cessation of the menstrual period) will also be evaluated against the Lupron Depot historical data.
The main objectives of this randomized trial comparing overminus lens treatment to non-overminus (spectacles without overminus or spectacles with plano lenses) are to determine: - The long-term on-treatment effect of overminus treatment on distance intermittent exotropia (IXT) control score. - The off-treatment effect of overminus treatment on distance IXT control score (following weaning and 3 months off treatment).
This study will investigate how the body processes nasal glucagon (NG) and the effect of nasal glucagon on the body. The study is expected to last about 50 days for each participant. The study is open to adults with type 1 or type 2 diabetes and will last about 50 days.
Worry postponement is a commonly recommended treatment component in cognitive behavioral therapy for Generalized Anxiety Disorder in which people are asked to postpone naturally occurring instances of worry to a designated 30 minute "worry period" later in the day. Despite being commonly recommended, there is little known about the efficacy and mechanisms of worry postponement. The purpose of this study is to determine the efficacy and mechanisms of change of a two-week worry postponement intervention in people with Generalized Anxiety Disorder. Ninety subjects with generalized anxiety disorder will be randomly assigned to two weeks of daily worry postponement, two weeks of worry monitoring, or an assessment only control condition. Changes in worry or associated features will be examined at post intervention and at a 2-week follow up.
