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 amount and speed of emergency department (ED) discharge instructions often make it difficult for patients/caregivers to know the final diagnosis and to remember instructions. We hypothesize that a video on ear infections and antibiotics' role in their management will facilitate caregiver understanding and will increase the likelihood of caregivers properly following discharge instructions. To verify this hypothesis, a large multi-centre clinical trial is needed. Prior to this, it is only ethical to conduct a smaller 'pilot' trial. Previously healthy children (6 months-5 years) diagnosed with mild ear infections at the McMaster Children's Hospital ED will be eligible to participate. If the child and caregiver decide to participate, before discharge, the caregiver will either: 1)watch the aforementioned video, 2)be given a pamphlet with the same information, or 3)standard of care (no additional information). Participants will fill a knowledge survey before discharge. The research assistant will contact all participants by phone to determine if the caregiver followed the discharge instructions.
Two-year double-masked trial of over-the-counter dosage of naproxen sodium vs placebo in 200 cognitively normal participants with a parental or multiplex first-degree family history Alzheimer's disease (AD) dementia. Primary outcomes are decline in cognitive function and slope of change in a summary Alzheimer Progression Score derived from serial assessment of neuroimaging, biochemical, and sensori-neural biomarker indicators of pre-clinical disease -- all believed likely to reflect progress of preclinical AD in this high risk cohort. Approximately 2/3 of participants have volunteered also for serial lumbar punctures for analysis of cerebrospinal fluid. A two-year off-treatment delayed-washout phase is planned to examine sustained treatment effects and evidence of disease modification.
This is a multicenter, randomized, double-blind study being conducted as a postmarketing requirement to the US Food and Drug Administration (FDA) to evaluate whether there is a lower starting dosage of lenvatinib 24 mg once daily (QD) that provides comparable efficacy but has a better safety profile in participants with radioiodine-refractory differentiated thyroid cancer RR-DTC with radiographic evidence of disease progression within the prior 12 months.
This trial will utilize a Molecular MicroscopeTM diagnostic system (MMDxTM) that combines the molecular and histopathological features of biopsies, plus clinical and laboratory parameters, to create the first Integrated Diagnostic System. This MMDxTM will be utilized to phenotype cutaneous melanoma biopsy samples to detect an immune responsive mRNA signature.
Clinical trial to determine the efficacy (sensitivity and specificity) of the Bladder EpiCheck test compared to the gold standard cystoscopy and pathology in patients under monitoring for recurrence of bladder cancer.
The aim of the study is to study whether training by residents or anesthesia assistants, on a recently introduced virtual-reality bronchoscopic simulator (ORSIM) improves performance of fiberoptic intubation in patients.
In addition to its role as the major regulator of glucose uptake into peripheral tissues, the hormone insulin is also a primary regulator of fat storage and fat burning of the body. Mechanistic animal studies have shown that high insulin may be the initial trigger for weight gain and be the proximal cause of obesity. There is currently no quick or non-invasive way of measuring insulin as research and clinical techniques require collection of a blood sample followed by a complicated and costly biochemical assay. The investigators will test the hypothesis that insulin levels can be accurately measured in saliva in humans following meals that elicit high and low blood insulin responses. Findings will help determine if insulin can be use as a valid fluid to track insulin changes in humans.
The purpose of this study is to evaluate the efficacy and safety of ustekinumab in pediatric participants aged greater than or equal to (>=) 6 through less than (<) 12 years with moderate to severe chronic plaque psoriasis
In North America, almost ½ million people undergo coronary artery bypass graft surgery annually and over 1/3rd develop chronic chest pain. The current study will randomize cardiac surgery patients to undergo slow sternal retraction for heart exposure (over 15 min.) versus standard-of-care (sternal opening over 30 seconds) and examine the incidence and severity of chronic post-sternotomy pain (CPSP) and quality-of life 3, 6 and 12 months post-operatively. The severity of acute post-operative pain will also be measured. Increased retraction time reduces forces required, which should translate to reduced nerve/tissue damage. If effective, this simple change in practice could be readily implemented with a major impact for patients and the health care system overall.
The primary purpose of this study is to evaluate the efficacy of a titration arm of tanezumab in which treatment is started at a lower dose (2.5 mg) and increased to a higher dose (5 mg) at Week 8, compared to giving 2 doses of tanezumab 2.5 mg or 2 doses of placebo. The study also evaluates the safety of the treatment regimens.
