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.
Angiotensin converting enzyme-2 (ACE2) is part of the renin-angiotensin system (RAS), which is involved in maintaining blood flow and electrolyte balance. It has been shown in obese and hypertensive individuals that levels of another molecule Angiotensin converting enzyme (ACE) are much higher, leading to inflammation, fibrosis, vasoconstriction and high blood pressure. ACE2 has a protective effect from ACE, leading to anti-inflammatory, anti-fibrotic and vasodilating effects. In animal models, it has been shown that aerobic exercise can increase levels of ACE2, while decreasing levels of ACE and offers protection to the cardiovascular system by keeping these two molecules balanced. Although the effects of exercise on the classical arm of the RAS have been studied significantly, ACE2 is a relatively new discovery and has not been studied as extensively in humans. The purpose of this research is to determine the effects of exercise training status on the RAS, specifically on ACE2 and its products.
This study will evaluate the long-term efficacy and safety of AXS-12 in narcoleptic subjects with cataplexy and excessive daytime sleepiness (EDS).
The Hearts in Rhythm Organization (HiRO) is a national network of Canadian researchers/clinicians, working towards a better understanding of the rare genetic causes of sudden cardiac death (SCD). The HiRO Hypertrophic Cardiomyopathy registry, biobank and imaging data repository (HiRO-HCM) is a multicenter study that will prospectively enroll patients with HCM as well as those carrying sarcomeric gene variants predisposing to HCM. The objectives of HiRO-HCM are: 1. to better understand the natural history of the disease and identify clinical markers and biomarkers for adverse outcomes; 2. to derive and validate risk prediction models for disease expression, complications and response to therapy; 3. to better define the genetic architecture of sarcomeric and non-sarcomeric HCM.
Elderly people who have multiple health problems are at higher risk of illness from viral respiratory infections, such as influenza (the flu) and COVID-19. This is especially true for residents in long-term care because the usual methods of infection control (handwashing, mask-wearing, and distancing) are difficult to enforce due to the memory problems of many residents and the frequently shared common spaces. It can also be difficult to prevent the spread of viral infections within long-term care because many residents are unable to tell their caregivers when they are feeling ill. Also, some elderly people do not show typical symptoms of infection (like fever), instead they may suddenly become confused or weak. This study will test if a safe form of ultraviolet light (far-UVC) can be effective as an extra method of disinfection (in addition to usual manual cleaning) against airborne and surface viruses that can cause respiratory infections.
Early detection through regular diabetic retinopathy screening (DRS) is an effective method of preventing vision loss by enabling earlier intervention and timely treatment. It is recommended that all people with diabetes receive regular DRS, either annually or bi-annually. Current DRS practice in Canada, however, falls remarkably short of recommended DRS rates resulting in preventable vision loss. In this project the investigators use population health-based approach to diabetes care. Linked provincial administrative data will be leveraged to consistently identify all those that have not had DRS in 425 days with the goal to improve outcomes, equity and potentially reduce the cost of care delivery.
The purpose of this study is to collect data needed to satisfy the European Union (EU) Medical Device Regulation (MDR) clinical post-market surveillance (PMS) and reporting requirements, and to support future regulatory submissions and peer-reviewed publications on device performance and safety.
Data from a series of Phase 2 and 3 studies of MDMA-assisted therapy conducted by the sponsor provide preliminary evidence that chronic Posttraumatic Stress Disorder (PTSD), independent of cause, is treatable with up to three sessions of MDMA-assisted therapy. This non-interventional study will serve as the long-term follow-up (LTFU) protocol for MDMA-assisted therapy clinical trials and will measure persistence of effectiveness using the Clinician-Administered PTSD Scale for DSM-5 (CAPS-5) as a measure of PTSD symptom severity. Additionally, this study will gather data to support health economics and cost effectiveness analyses of this treatment. Participants who have received at least one dose of Investigational Medicinal Product (IMP) in the main study will be eligible to participate in this study.
Frail older adults are commonly prescribed blood pressure medication, yet it is unclear if blood pressure medication is actually beneficial for them. Observational studies in this population suggest blood pressure medication has limited benefit and may even be harmful, including an increased risk for falls and cognitive impairment. Randomized controlled trials are needed to confirm this. This study is a randomized controlled trial of blood pressure medication deprescribing, amongst long-term care residents with systolic blood pressure lower than 135 mmHg. In the intervention group, with physician consent, the facility pharmacist or nurse practitioner will continually reduce antihypertensives provided an upper systolic threshold of 145 mmHg is not exceeded. The control group will receive usual care. The primary outcome is all-cause mortality but the study will also be tracking all-cause hospitalization or emergency room visits, hip fractures, falls, skin ulceration, renal insufficiency, cognitive and behavioural outcomes and costs of care. The hypothesis is that avoiding unnecessarily low systolic blood pressure is beneficial in a frail, end-of-life population.
The goal of this clinical study is to learn more about the long-term safety, effectiveness and prolonged action of Kite study drugs, axicabtagene ciloleucel, brexucabtagene autoleucel, KITE-222, KITE-363, KITE-439, KITE-585, and KITE-718, in participants of Kite-sponsored interventional studies.
Patients with postoperative hyperglycemia have higher complication rates and worse outcomes than patients with in-target glucose, including longer length-of-stay, more admissions to intensive care, increased readmission rates, and higher risk of infection. There are 35-40% of surgical patients at risk of postoperative hyperglycemia, including 20-30% of patients with diabetes, 10% with undiagnosed diabetes, and another 5-10% without diabetes who will have hyperglycemia. Data demonstrate significant quality and practice gaps that contribute to postoperative hyperglycemia in Alberta; 43% of patients with diabetes had no postoperative glucose measurements and two-third had postoperative hyperglycemia. The multi-disciplinary Perioperative Glycemic Management Pathway (PGMP) has been demonstrated to reduce postoperative hyperglycemia and improve outcomes for surgical patients in pilot-testing. This project will confirm the effects of the PGMP on (1) postoperative glycemic management; (2) length-of-stay; (3) readmission rates and (4) cost savings; compared to usual care in surgical patients admitted for >24-hours postoperatively. We will implement the PGMP in 12 services in 6 hospitals in Alberta using implementation science and an evidence-informed knowledge translation approach. Impact will be analyzed using a stepped-wedge study design and will include formal evaluation of cost-effectiveness and implementation, clinical, and patient-reported outcomes. The primary efficacy outcome is change in length-of-stay pre/post implementation. Secondary clinical outcomes include the 30-day readmission rate, surgical site infection rate, 30-day mortality, and one-year mortality. We will implement the PGMP for 23,200 patients, and reduce postoperative hyperglycemia and associated complications for 7,665 patients, avoiding the expenditure of >$24.6 million for a return on investment of 1,810%.
