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.
Purpose: Depression affects 12.6% of Canadians at some point in their life. Depression is associated with staggering personal and economic costs. There are several treatments that have been shown to treat episodes of depression when they occur. Unfortunately, more than half who respond to these treatments go on to re-experience an episode of depression. Even with psychological and pharmacological interventions designed to prevent future episodes, relapse and recurrence of the disorder remain alarmingly high. A patient-focused and self-directed intervention that harnesses the effects of an Eastern-influenced concept, called self-compassion, has shown tremendous promise in treating acute depression. Self-compassion is being moved by one's own suffering, and a desire to alleviate such suffering. Objectives: In the proposed project, the investigators will examine whether a self-compassion intervention is effective in preventing relapse/recurrence of depression over a 12-month period among people who are at high risk for relapse. The investigators will also examine whether the intervention works to prevent depression by increasing the innate ability to bounce back from stress, a concept known as resilience. Methodology: 120 participants with a history of depression will be randomly assigned to the self-compassion intervention or a self-assessment reflection condition, and their respective relapse rates will be examined over a period of 12 months. Importance to Research: This will be the first study to examine the effects of self-compassion as a preventive intervention for depression. Impact on health: If successful, this new intervention can be used by thousands of people in Saskatchewan and Canada who are at risk for depression relapse.
The aim of the COVI-PRONE Trial is to determine if early awake prone positioning in COVID-19 patients with hypoxemic respiratory failure; irrespective of the mode of oxygen delivery; reduces the need for invasive mechanical ventilation.
This is an international, multicenter, parallel-group, randomized, double-blind, placebo controlled, study in hospitalized adult patients with coronavirus disease 2019 (COVID-19) in the United States, Brazil, Mexico, Argentina, India, Canada, and United Kingdom. The study is evaluating the effect of dapagliflozin 10 milligrams versus placebo, given once daily for 30 days in addition to background local standard of care therapy, on reducing complications and all-cause mortality, or improving clinical recovery.
The purpose of this study is to assess the vision improvement achieved by patients with late stage dry age-related macular degeneration who received corneal treatments by a low vision aid device.
An individual's ability to adequately cope with short- or long-term increases in ambient temperature is critical for maintaining health and wellbeing. Prolonged increases in temperature (heatwaves) pose a serious health risk for older adults, who have a reduced capacity to regulate body temperature. Currently, however, there is a lack of information regarding how different environmental conditions experienced during heatwaves impact body temperature regulation and physiological function. This is particularly important in the context of ambient conditions in the home, where older adults spend the majority of their time. This project will address this important issue by exposing healthy older adults to prolonged (8-hour) simulated heatwaves comprising a range of environmental conditions representative of an actively cooled domicile through to a worst-case scenario (i.e., no capacity for home cooling). The investigators will directly measure their ability to regulate their body temperature and the associated impact on the autonomic control of the heart. The investigators anticipate that physiological strain will be mild during prolonged exposure to conditions below the currently recommended thresholds set by Toronto Public Health (26°C). However, at higher indoor temperatures, impairments in body temperature and cardiovascular regulation will be seen.
This study aims to evaluate the experience of Alberta patients with inflammatory arthritis who participate in the the RAPPORT-ONTRAAC registry during the COVID-19 pandemic, specifically comparing the experience of those taking anti-malarial medications compared to those who do not. This registry includes approximately 2500 northern Alberta patients with inflammatory arthritis who receive highly complex therapies which may be associated with side effects. This program of data collection and research has been evaluating the effectiveness and safety as well as associated health care costs of rheumatoid and psoriatic arthritis patients since 2004. The principle investigators are based at the University of Alberta while the co-investigators are academic rheumatologists at the University of Alberta. The registry has approximately 900 patients taking anti-malarials combined with their complex therapies and ~ 1500 not on anti-malarials in combination with their complex therapies. We aim to perform a case control study evaluating the impact of anti-malarial drugs (eg. hydroxychloroquine and chloroquine) on the development of COVID-19 compared to those patients who are not on anti-malarial drugs over the next 6-12 months. In addition to frequent e-mail surveys screening for the clinical symptoms of COVID-19 and understanding their concomitant arthritis medication use, we will compare the healthcare outcomes of both groups of arthritis patients with and without COVID-19 for the duration of the pandemic. This information will provide critical information beyond an anecdotal level on whether or not anti-malarials truly provide a protective benefit against COVID-19 or reduce the severity of infection. A blood sample from all participants (Covid-19 positive and negative) will be drawn approximately six months into the study for measurement of antibodies to Covid-19 and possible blood types and HLA alleles. Additionally, this study will be linked to another study "Persistence of SARS-Cov2 in immunocompromised patients" which will specifically evaluate COVID-19 serology and nasopharyngeal swab findings in the subset of patients who develop COVID-19.
Patent ductus arteriosus (PDA) is the most common cardiovascular problem that develops in preterm infants. Persistent PDA may result in higher rates of death, chronic lung disease (CLD), pulmonary hemorrhage, necrotizing enterocolitis (NEC), acute kidney injury (AKI), intraventricular hemorrhage (IVH) and cerebral palsy. Currently available options to treat a PDA include indomethacin, ibuprofen or acetaminophen followed by surgical or interventional closure of the PDA if medical therapy fails. Wide variation exists in PDA treatment practices across Canada. A survey conducted through the Canadian Neonatal Network (CNN) in 2019 showed that the most common choice of initial pharmacotherapy is standard dose ibuprofen. In view of the high pharmacotherapy failure rate with standard dose ibuprofen, there is a growing use of higher doses of ibuprofen with increasing postnatal age (with 32% of respondents currently adopting this practice) in spite of the fact that effectiveness and safety of higher ibuprofen doses have not been established in extremely preterm infants [<29 weeks gestational age (GA)]. In view of this large practice variation across Canadian neonatal intensive care units (NICUs), we are planning a comparative effectiveness study of the different primary pharmacotherapeutic agents used to treat the PDA in preterm infants. Aims Primary: To compare the primary pharmacotherapeutic practices for PDA closure and evaluate their impact on clinical outcomes in extremely preterm infants (<29 weeks GA) Secondary: To understand the relevance of pharmacotherapeutic PDA treatment with respect to clinical outcomes in the real world. Methods: Participants: Extremely preterm infants (<29 weeks gestational age) with an echocardiography confirmed PDA who will be treated according to attending team Interventions: 1. Standard dose ibuprofen [10-5-5 regimen, i.e., 10mg/kg followed by 2 doses of 5mg/kg at 24h intervals] 2. Adjustable dose ibuprofen [10-5-5 regimen if treated within the first week. Higher doses of ibuprofen up to a 20-10-10 regimen if treated after the postnatal age cut-off for lower dose as per the local center policy] 3. Intravenous indomethacin [0.1-0.3mg/kg every 12-24h for a total of 3 doses]. 4. Acetaminophen [Oral/intravenous] (15mg/kg every 6h) for 3-7 days Outcomes: Primary: Failure of primary pharmacotherapy (Need for further medical and/or surgical/interventional treatment following an initial course of pharmacotherapy). Secondary: (a) Receipt of 2nd course of pharmacotherapy; (b) Surgical/interventional PDA closure; (c) CLD (d) NEC (stage 2 or greater) (e) Severe IVH (Grade III-IV) (f) Definite sepsis (g) Stage 1 or greater AKI; (h) Post-treatment serum bilirubin; (i) Phototherapy duration; (j) All-cause mortality during hospital stay.
The objective of this study is to quantify motor performance, this study will use an eye movement Fitts' task to examine the effects of cervical spine manipulation on participants with chronic neck pain and the subsequent changes to saccade movement time. This study will also include a head movement Fitts' task which has previously reported a reduction in head movement time in chronic neck pain participants after cervical spine manipulation. This is an observational within-subjects design that involves a pre/post cervical spine manipulation intervention on participants (n=20) with chronic neck pain and asymptomatic controls (n=20). All participants will complete an eye movement and head movement Fitts' task before and after cervical spine manipulation to identify any changes in saccade and head movement time, saccade and head peak velocity, and time to peak saccade and head velocity.
This is a randomized, double-blind, double-dummy, active-controlled, multi-center study to assess the efficacy and safety of abrocitinib 200 mg (2 x 100 mg tablets) administered orally QD compared with dupilumab 300 mg administered by subcutaneous injection every other week (as per label guidelines) in adult participants on background topical therapy, with moderate to severe AD. The treatment duration is 26 weeks. A total of approximately 600 participants will be enrolled from approximately 220 sites globally. Approximately 600 participants will be randomly assigned to study intervention. There are primary efficacy assessments at Week 2 and Week 4, and a key secondary efficacy assessment at Week 16. Efficacy and safety endpoints will be assessed throughout the entire study. Exploratory endpoints related to hand eczema efficacy will be assessed throughout the study.
The Post discharge after surgery Virtual Care with Remote Automated Monitoring technology (PVC-RAM) Trial is a multicentre, parallel group, superiority, randomized controlled trial to determine the effect of virtual care with remote automated monitoring (RAM) technology compared to standard care on days alive at home during the 30-day follow-up after randomization, in adults who have undergone semi-urgent (e.g., oncology), urgent (e.g., hip fracture), or emergency (e.g., ruptured abdominal aortic aneurysm) surgery. It will also determine, during the first 30 days, the effect of virtual care with RAM technology on several secondary outcomes, including: 1. hospital re-admission; 2. emergency department visit; 3. urgent-care centre visit; 4. acute-hospital care (i.e., a composite of hospital re-admission and emergency department or urgent-care centre visit) 5. brief acute-hospital care (i.e., acute-hospital care that lasts <24 hours); 6. all-cause hospital days; 7. medication error detection; 8. medication error correction; and 9. death. An additional secondary objective is to determine the effect of virtual care with RAM technology on pain at 7, 15, and 30 days and 6 months after randomization.
