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 goal of this trial is to examine the effects of a single high-fat meal with or without the co-ingestion of dietary nitrate on exercise-mediated sympatholysis. The main questions it aims to answer are: 1. What are the mechanisms responsible for reduced exercise-mediated sympatholysis following a high-fat meal 2. Can dietary nitrate prevent the declines in exercise-mediated sympatholysis Participants will be asked to complete three study visits in a randomized order: 1. Low-fat meal 2. High-fat meal 3. High-fat meal plus dietary nitrate Exercise-mediated sympatholysis will be measured using Doppler ultrasound via a protocol involving rhythmic handgrip exercise and a lower body negative pressure stimulus. Sympatholysis will be assessed before each meal, and at 1, 2, and 3 hours post-prandial.
The purpose of the study is to evaluate the safety, tolerability, pharmacokinetics, and pharmacodynamics of VX-670 at different single and multiple doses in participants with DM1.
The aim of this project is to conduct a pilot randomized controlled trial (RCT) to evaluate the feasibility and preliminary effectiveness of a virtual group based self-management program (SMP) in adolescents with JIA across different provinces compared to a wait-list control group receiving only standard of care. Participants in the SMP group will partake in four 60-90 minute group sessions conducted over 8 weeks. The intervention is a multifaceted program that includes JIA disease education, self-management strategies, and peer support. Both the interventional and control group will be asked to complete baseline and post-test measures. Participants in the control group will be offered the SMP after completion of the post-control outcome measures.
The primary objective of this study is to assess the efficacy of ALXN2220 in the treatment of adult participants with ATTR-CM by evaluating the difference between the ALXN2220 and placebo groups as assessed by the composite endpoint of all-cause mortality (ACM) and total cardiovascular (CV) clinical events.
Cancer therapy-related cardiac dysfunction (CTRCD) is when the heart's ability to pump oxygenated blood to the body is compromised. It is a side effect of cancer therapy which can occur as commonly as in 1 in 5 patients. When this occurs, heart failure medications are started to protect the heart from progressing to heart failure. With early detection and treatment, heart function recovers to normal in >80% of patients. Unfortunately, heart failure medications are associated with an undesirable long-term pill burden, financial costs, and side-effects (e.g., dizziness and fatigue). As a result, cancer survivors frequently ask if they can safely stop their heart failure medications once their heart function has returned to normal. Currently there is no scientific evidence in this area of Cardio-Oncology. To address this knowledge gap, the investigators have designed a randomized control trial to assess the safety of stopping heart failure medication in patients with CTRCD and recovered heart function. The investigators will enrol patients who have completed their cancer therapy and are on heart medications for their CTRCD, which has now normalized. The investigators will randomize patients with no other reasons to continue heart failure medications (e.g., kidney disease) to continuing or stopping their heart medications safely. All patients will undergo a cardiac MRI at baseline, 1 and 5 years with safety assessments at 6-8 weeks, 6 and 9 months and 3 and 5 years. The investigators will determine if stopping medications is non-inferior to continuing medications by counting the numbers of patients who develop heart dysfunction by 1 year in each group.
This is a phase II, proof of concept, placebo-controlled, randomized clinical trial, assessing the effect of canagliflozin on cardiac structure and function in patients with advanced renal disease, including those on maintenance dialysis. Our primary aim is to determine the effect of canagliflozin on cardiac structure and function in patients with advanced chronic kidney disease (CKD), compared with placebo. We hypothesize that canagliflozin will improve left ventricular (LV) hypertrophy in patients with advanced CKD. Our secondary aims are to describe the effect of canagliflozin on other cardiac magnetic resonance imaging parameters and surrogate markers of efficacy in this population.
Currently, daratumumab, lenalidomide, and dexamethasone are given continuously (non-stop). Some recent observations suggest that stopping daratumumab after about a year and a half of treatment may work just as well as giving it continuously with lenalidomide and dexamethasone. This study is being done to answer the question: is less daratumumab treatment as good as more?
The aim of this randomized clinical trial is to verify the efficacy of VR immersion over a muted cartoon on a wall-mounted TV to decrease dental fear and anxiety of children undergoing dental procedures. The study also aims to gain insight on the satisfaction of parents and healthcare providers on the use of VR during dental appointments. Main research question: Does VR immersion compare to a cartoon on a wall-mounted TV is more efficacious to decrease dental fear and anxiety of children requiring dental procedures? Participants will be playing through a VR immersive game wearing a eye-tracking VR headset that requires no movement of the head to play, facilitating the dental procedure. The investigators will take measures of the stress levels of participants and their parents using a validated stress scale and also by taking salivary samples to verify the levels of a stress biomarker (alpha-amylase).
This study is conducted to determine the safety and tolerability of INCB161734 as a single agent or in combination with other anticancer therapies.
Anhedonia is a core feature of major depressive disorder (MDD) (DSM-5). Functional magnetic resonance imaging (fMRI) studies have associated anhedonia in MDD with altered frontostriatal activity and functional connectivity relative to controls. Conversely, antidepressant treatment is associated with increased ability for patients with MDD to sustain frontostriatal activity in a manner predictive of decrease in anhedonia and gains in daily positive affect. Novel interventions are needed to address anhedonia. Repetitive transcranial magnetic stimulation (rTMS) of the dorsolateral prefrontal cortex (DLPFC) has been shown to activate striatal reward circuits. Positive Affect Treatment (PAT) was developed to treat deficits in reward processing; a critical skill patients are trained on in PAT involves recounting and savouring of positive experiences. However, amotivation impedes some patients from engaging in positive activities, prompting the development of virtual reality reward training (VR RT) for this skill. Evidence is building that brain state at the time of rTMS impacts its therapeutic effect. For example, imaginal exposure and individualized symptom provocation just prior to rTMS enhances its therapeutic effect on post-traumatic stress disorder and obsessive-compulsive disorder, respectively. It is unknown whether VR RT can augment rTMS for MDD and if so whether it is mediated by enhancing changes in frontostriatal activity or functional connectivity. The current study is significant for multiple reasons. As mentioned, there is a paucity of effective treatments for anhedonia and this study may inform development of a novel treatment strategy that harnesses findings from affective neuroscience. Recent economic analysis suggests that rTMS can be more cost-effective than pharmacotherapy or ECT for treatment-resistant depression (Ontario Health, 2021). Our findings will provide insight on ways to synergize specific psychotherapeutic techniques with targeted stimulation of brain circuits to more effectively treat subtypes of depression.
