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.
Pulmonary embolism, or clots blocking the blood vessels of the lungs, is a common clinical condition requiring treatment with blood thinners. In most patients, recovery is complete. A small proportion of patients, however, develop complications (high blood pressure in the lung circulation, i.e. pulmonary hypertension). Persisting breathlessness during activity is a common symptom in many of these patients and leads to a reduced ability to engage in daily physical activity. The reason for this activity-related breathlessness remains uncertain and is the main question of the proposed study. Using new sophisticated technology, the investigators will determine the root causes of perceived breathing difficulty. The investigators will test the idea that breathlessness is fundamentally the result of increased drive to breathe from control centers in the brain. The investigators will measure drive to breathe by measuring the electrical activity descending from the brain to the main muscle of breathing - the diaphragm. The investigators will discover if the increased drive to breathe is due to accumulation of carbon dioxide in the blood as a result of poor blood perfusion of areas of the lung due to the effects of blockage by clots. The investigators also will investigate whether weakness and fatigue of the muscles of breathing, as a result of the high breathing demands that are present in patients with blood clots in the lungs, contribute to breathlessness. With this information it is hopeful that better treatment options will be developed to relieve this distressing symptom.
The main purpose of this study is to evaluate the anti-tumor activity of bempegaldesleukin (NKTR-214) in combination with nivolumab by assessing the objective response rate (ORR) in cisplatin ineligible, locally advanced or metastatic urothelial cancer patients.
This study will evaluate the efficacy and safety of tenecteplase compared with placebo in participants with acute ischemic stroke (AIS). All participants will receive standard-of-care therapy according to AmericanHeart Association/American Stroke Association clinical guidelines (2018). To determine eligibility for randomization, all participants will undergo multimodal CT or MRI at baseline. Only participants with a vessel occlusion (ICA or MCA M1/M2) and penumbral tissue will be randomized. The primary analysis is to compare the efficacy of tenecteplase versus placebo in all participants at Day 90.
The purpose of this study is to evaluate long-term safety and tolerability data in eligible CLCZ696B2319 (PANORAMA-HF) patients receiving open-label sacubitril/valsartan.
Other psychiatric disorders, including anxiety, often co-occur with adult ADHD; with 85% of ADHD patients having at least one other psychiatric condition. The presence of a co-occurring anxiety disorder has been associated with additive clinical effects, leading to more global impairment, poorer outcome, greater resistance to treatment and increased costs of illness. Stimulants are effective first-line treatments for adult ADHD patients, however the literature has mostly examined these treatments in pure ADHD populations (i.e. without other psychiatric disorders). Thus, there is little information to guide physicians in making treatment decisions for patients with ADHD and a co-occurring condition. This trial aims to evaluate the efficacy and safety of methylphenidate hydrochloride controlled release capsules (Foquest) in treating adults aged 18-65 years with DSM-5 ADHD with and without a co-occurring anxiety disorder.The study uses a 14-week, randomized, placebo-controlled, cross-over design.
The main objective of the study is to evaluate the use of Virtual Reality (VR) in managing pain and anxiety levels during common pediatric orthopaedic outpatient procedures which include: cast application, cast removal, hardware removal (ie. pins and screws), and botox injections.
The purpose of the proposed research is to develop, implement, and test the efficacy of a theory-driven evidence-based peer leadership program for elementary school students (Grade 6/7; age 11/12 years) in relation to (a) their own leadership skills and their leadership self-efficacy (i.e., confidence to lead), as well as (b) the physical literacy of younger (Grade 3/4; age 8/9) students with whom they are partnered.
Given the ongoing national opioid epidemic, an increased interest has developed in optimizing opioid prescribing practices of physicians, including otolaryngologists. Endoscopic sinus surgery (ESS) is one of the most commonly performed surgeries by otolaryngologists with over 250,000 ESS's performed annually in the U.S. Multiple studies have shown that, compared to the amount patients actually consume, otolaryngologists prescribe a high quantity of opioids to patients recovering from ESS). It has been shown that these excess opioid medications contribute to prolonged use or abuse by the patient, family members, or friends. The purpose of this study is to better understand the pain management requirements of patients who undergo ESS for recurrent acute rhinosinusitis (RARS) or chronic rhinosinusitis (CRS). This prospective, randomized, multi-institutional controlled trial will aim to determine the degree to which pain following ESS can be adequately controlled by non-opioid medications. It will also determine whether post-ESS narcotic use can be avoided entirely, or at least significantly limited. Patients will be randomized into two groups, each of which will receive a stepwise analgesic regimen consisting of acetaminophen and oxycodone or acetaminophen and ibuprofen. Pain will be assessed daily using visual analog scales (VAS) and the Brief Pain Inventory (BPI). The results of this study will help to develop a standardized approach to pain management in the post-ESS setting and help to elucidate the role of non-opioid pain medications. The ultimate goal would be to positively affect opioid prescribing patterns among surgeons who perform ESS in order to significantly reduce the quantity of opioids prescribed to patients while continuing to adequately manage patients' pain.
The purpose of this study is to evaluate the safety, tolerability, pharmacokinetics and pharmacodynamics of single- and multiple doses of ARO-APOC3 in healthy adult volunteers and in patients with severe hypertriglyceridemia and familial chylomicronemia syndrome (FCS).
This project proposes to characterise the microbiome-derived metabolites produced upon ingestion of bioactive precursor-rich meals by healthy volunteers in order to investigate the relationship between gut microbiome composition and the nature of dietary metabolites production.
