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.
Every 3 minutes a new case of diabetes is diagnosed in Canada, mostly type 2 diabetes (T2D) increasing the risk for heart disease. T2D and heart disease share many common risk factors such as aging, obesity and unhealthy lifestyle. Paradoxically however, while lowering blood LDL, commonly known as "bad cholesterol", is protective against heart disease, research over the past 10 years have shown that the lower is blood LDL, the higher is the chance of developing T2D. This phenomena is happening whether blood LDL is lowered by a common drug against heart disease called Statins, or by being born with certain variations in genes, some of which are very common (~80% of people have them). To date, it is unclear why lowering blood LDL is associated with higher risk for diabetes, and whether this can be treated naturally with certain nutrients. Investigators believe that lowering blood LDL by forcing LDL entry into the body tissue through their receptors promotes T2D. This is because investigators have shown that LDL entry into human fat tissue induces fat tissue dysfunction, which would promote T2D especially in subjects with excess weight. On the other hand, investigators have shown that omega-3 fatty acids (omega-3) can directly treat the same defects induced by LDL entry into fat tissue. Omega-3 is a unique type of fat that is found mostly in fish oil. Thus the objectives of this clinical trial to be conducted in 48 subjects with normal blood LDL are to explore if: 1. Subjects with higher LDL receptors and LDL entry into fat tissue have higher risk factors for T2D compared to subjects with lower LDL receptors and LDL entry into fat tissue 2. 6-month supplementation of omega-3 from fish oil can treat subjects with higher LDL receptors and LDL entry into fat tissue reducing their risk for T2D. This study will thus explore and attempt to treat a new risk factor for T2D using an inexpensive and widely accessible nutraceutical, which would aid in preventing T2D in humans.
Prospective, open label, single arm, First in Human (FIH) clinical study to assess safety and efficacy of the CorNeat Keratoprosthesis, a synthetic cornea, for the treatment of corneal blindness
The objective is to compare IV vernakalant to IV procainamide for the ED management of acute AF patients. If vernakalant proves to be more effective, faster, and safer than IV procainamide, this will give clinicians an important alternative for pharmacological cardioversion of acute AF. The investigators propose a pragmatic comparative effectiveness trial entailing an open label, randomized controlled trial at 12 large Canadian EDs. Study subjects will be randomized to 1 of 2 treatment arms: 1) Patients will receive an initial infusion of 3mg/kg of IV vernakalant over 10 minutes, followed by a second dose of 2mg/kg over 10 minutes, if necessary, or 2) Patients will receive a continuous infusion of 15mg/kg of IV procainamide over 60 minutes. The primary aim will be to compare conversion to normal sinus rhythm between the two drugs. The investigators will include stable patients presenting with an episode of acute AF of at least 3 hours duration, where symptoms require urgent management and where immediate cardioversion is a reasonable option. Using the integrated consent model, research assistants will obtain verbal consent from eligible patients.
Postpartum depression (PPD) already affects up to 1 in 5 women and left untreated costs $150,000 per case over the lifespan. Under normal conditions, just 10% of women with PPD get evidence-based treatment, a situation that has worsened substantially during COVID-19. The purpose of this study is to a assess if self-referred, online adaptation of a 1-Day Cognitive Behavioural Therapy (CBT)-Based Workshop for PPD delivered up to 30 women at a time can lead to reductions in PPD, if the workshops are cost-effective, and to assess workshop impact on common complications of PPD (anxiety, partner relationship discord, problems with mother-infant attachment). 388 women will be randomized to receive either immediate treatment or treatment 12 weeks later (waitlist control). Study measures will be collected at baseline (immediately before treatment workshop) and 12 weeks later (immediately before wait list control workshop).
The primary objective of this pilot study is to determine the safety and feasibility a 12-week virtually supported home-based aerobic and resistance exercise program progressing cancer survivors with Multiple Myeloma to meet standards identified in the 2019 Exercise Guidelines for Cancer Survivors. The protocol will be measuring recruitment, adherence, completion, cost tracking, as well as fitness and quality of life outcomes. The study will be a single-group prospective before and after study that will help inform a future larger-scale project. We will aim to recruit 25 participants. The Health Research Ethics Board of Alberta Cancer Committee will approve this study. Participants will participate in a combined resistance and aerobic exercise program biweekly for 12 weeks. Exercise sessions will be supported and progressive in nature, between 40 and 75 minutes each. Analyses: fitness testing and quality of life scales will be administered before and after the intervention. Scores will be compared to evaluate changes over the course of the intervention. Safety and feasibility information will be collected throughout the study and evaluated to determine program feasibility. Program satisfaction will be evaluated using a satisfaction survey.
Prostate cancer is the third most common cause of cancer death in men. Most patients with localized prostate cancer will be cured with surgery or radiation therapy, but up to 35% of patients will have their prostate cancer return. Whether it has returned locally or distantly determines which type of treatment they will receive. Current conventional imaging modalities have limitations particularly at low prostate specific antigen levels. This study proposes to use Gallium-68-PSMA-11 (68Ga-PSMA-11) Positron Emission Tomography / Computer Tomography (PET/CT) scans which targets prostate-specific membrane antigens (PSMA) to detect where in the body the prostate cancer has recurred.
Prescription opioids contribute to opioid related deaths, overdose and addiction. Unused prescribed opioids are not routinely being stored or disposed of appropriately and their availability is associated with harms. Maximum daily doses prescribed are higher than that recommended in a significant number of patients. This study is designed to help have appropriate doses and quantities of opioids dispensed for the treatment of short-term pain. Rather than targeting prescribing, this study targets the dispensing process by training community pharmacists to assess the appropriateness and safety of opioid prescriptions for short-term pain and to work with patients to partially fill prescriptions if the quantities prescribed are deemed excessive. Patient education tools were developed to help promote understanding of opioid safety, including the use of appropriate quantities, safe storage and safe disposal. Pharmacists in five randomly selected regions in Ontario, Canada are targeted for the eLearning intervention. The primary study outcome is the quantities dispensed for initial opioid prescriptions for short-term pain in the intervention regions compared to ten control regions.
The aim of DETECT is to prove the feasibility of a multicenter phase III trial testing the hypothesis that intensive blood pressure control immediately after successful endovascular stroke thrombectomy can improve patient outcomes. Patients with stroke who have ongoing high blood pressure after successful clot retrieval will be included. Participants will be randomly placed (like flipping a coin) in one of two groups. There will be a 50% chance of each patient being placed to either group. The first group will be allowed to have a higher blood pressure range that is consistent with current recommendations. The second group will be given medications to bring their blood pressure down into a normal range. These blood pressure targets will be maintained for 48 hours. We will collect patient brain images and levels of stroke disability up to 90 days after their clot retrieval.
In this 16-week randomized control study, health care workers will receive a bolus dose followed by a weekly dose of vitamin D or a placebo bolus and weekly dose. This study will test whether high-dose of vitamin D supplementation decreases the incidence of laboratory-confirmed COVID19 infection (primary outcome), reduces illness severity, duration, as well as work absenteeism among health care workers (HCW) in setting at high-risk of contact with COVID-19 cases in high COVID-19 incidence areas.
This study will leverage a current longitudinal study of brain development in preterm children. In the Miller/Grunau Trajectories study, preterm children are returning for follow-up at 8-9 years. At this appointment, children undergo MRI and neurodevelopmental testing. Children who are identified with DCD at this appointment will be invited to participate in this intervention study. Participants will have a 2nd MRI 12 weeks after the first scan. They will then receive 12 weekly sessions with an occupational therapist, followed by a third MRI. Children with DCD who were born very preterm (<32 weeks gestational age) who are not part of the Miller/Grunau study are also eligible to participate.
