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 is a prospective, randomized, multi-center, metal hypersensitivity study comparing OXINIUM and cobalt chrome femoral components in subjects with failed total knee arthroplasty (TKA).
This is a multi-site, double-blind, randomized, controlled food intervention study being conducted at the Canadian Centre for Agri-Food Research in Health and Medicine (CCARM) in Winnipeg and the Mayo Clinic, Rochester, MN, to examine the effects of a portfolio of functional foods on blood glucose and lipids, and blood vessel function in individuals with prediabetes. A total of 116 participants (n=58/site) with prediabetes (hemoglobin A1c ≥6.0 & <7.0 and no glucose-lowering medications) and body-mass index (BMI) 18-40 will be recruited for a 12-week clinical trial to determine the effect of eating 2 items containing functional ingredients daily compared to 2 similar items lacking the functional ingredients. Study foods provided are to be incorporated into participant's usual diet.
Bilevel Positive Airway Pressure (BiPAP) is increasingly being reported as an effective and safe method of respiratory support for children with severe asthma exacerbations unresponsive to standard therapies and with impending respiratory failure. Much of the evidence base supporting its use comes from retrospective observational studies, and there is currently a lack of data from randomized controlled trials to inform this practice. The investigators hypothesize that the use of BiPAP in children with moderate to severe asthma exacerbations could reduce the length of hospital stay, need for invasive ventilation, and use of intravenous bronchodilators. The investigators aim to test this hypothesis by randomizing children attending the Emergency Department with a moderate to severe clinical severity score refractory to inhaled bronchodilators to receive either BiPAP in addition to standard asthma care, or standard care alone.
This study is a multi-center, randomized, triple-blind, placebo-controlled parallel-group trial, in which each participant is offered an N-of-1 trial. The purpose of this study is to assess the efficacy and safety of melatonin (3 mg or 6 mg) compared with placebo for initial insomnia in children with attention-deficit disorder.
The investigators goal is to conduct a pilot randomized controlled trial (RCT) whose purpose is to determine the feasibility of a randomized trial designed to determine if either inhaled beclomethasone or a combination of inhaled beclomethasone/salbutamol (Clenil Compositum) are superior to placebo in treating pre-school aged children with an acute wheezing episode.
This study will evaluate the role of Metformin on liver fibrosis in HCV-HIV co-infected and HCV mono-infected patients with insulin resistance receiving DAA HCV treatment.
Once kidney function goes below 10 to 15 percent of normal, dialysis treatments or a kidney transplant are necessary to sustain life. One type of dialysis is hemodialysis which cleans blood by removing it from the body and passing it through a dialyzer, or artificial kidney. To maximize the amount of blood cleansed during hemodialysis treatments, there should be continuous high volumes of blood flow. A fistula used for hemodialysis is a direct connection of an artery to a vein. Once an arteriovenous fistula (AVF) is created it is a natural part of the body. This is the preferred type of access because once the fistula properly matures and gets bigger and stronger; it provides an access with good blood flow that can last for decades. After the fistula is surgically created, it can take weeks to months before the fistula matures and is ready to be used for hemodialysis. There have been surgical factors identified; one of them being the anesthetic used which may cause a fistula not to survive. This study will look at comparing 3 anesthetic techniques: axillary block (AB) versus stellate ganglion (SGB) block+local anesthetic versus local anesthetic (LA).
Clopidogrel efficacy appears diminished in patients with type 2 diabetes (T2D) who continue to show an increased risk of adverse cardiovascular events and mortality compared to those without T2D.The aim of the first project is to describe the pharmacokinetic (PK) profile of three antiplatelet drugs in 4 groups of patients according to their diabetic or non-diabetic status. To this end, PK profiles will be determined after a single oral dose of 300 mg clopidogrel, 60 mg prasugrel and 180 mg ticagrelor in patients (n=108); 1) with T2D and good glycemic control; 2) with T2D and poor glycemic control; 3) with insulin-treated diabetes; and 4) non-diabetic subjects.
Infantile Spasms, is an rare age-specific epilepsy of early infancy. A 2012 American Academy Neurology/ Child Neurology Society practice parameter update on the medical treatment of infantile spasms concluded: adrenocorticotrophic hormone or vigabatrin may be offered for short-term treatment of infantile spasms. There was insufficient evidence to recommend the use of prednisolone, dexamethasone, and methylprednisolone. The cost of ACTH and the side effects of vigabatrin have led to the consideration of alternative medications to treat infantile spasms. The United Kingdom Infantile Spasms Study (UKISS) in 2004, comparing the efficacy of intramuscular synthetic ACTH to high dose oral prednisolone, showed a response rate of 74% for ACTH and 70% for prednisolone. Since the UKISS paper was published, many institutions in the United States and Australia have used oral prednisolone instead of ACTH, partly due to the exorbitant cost of intramuscular ACTH but also its ease of use and better adverse event profile compared to ACTH. Prednisolone and vigabatrin are both oral medications, which can be initiated promptly upon diagnosis of infantile spasms, expediting treatment and shortening treatment lag time. Because the UKISS trial is the only Class 3 study providing evidence for oral prednisolone in the first-line treatment of infantile spasms, further prospective studies are needed.
The objectives of this 15-day study are: 1. To compare steady-state trough plasma concentrations of clozapine and its metabolite norclozapine when given once daily and twice daily (at the same total daily dose) 2. To determine if frequency of clozapine administration has an effect on: 1. Symptoms of schizophrenia 2. Adverse effects of clozapine 3. Fasting blood glucose, lipids, creatinine, and urea 4. Weight and waist circumference
