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.
Cardiac failure is the major cause of death in patients with thalassemia and chronic blood transfusion-related iron overload. The treatment of thalassemia has been revolutionized over the past decade with the implementation of cardiac MRI based assessment of iron overload. This has enabled detection of cardiac iron overload prior to symptomatic heart failure and now allows for timely therapy which has resulted in a substantial decrease in mortality. However, currently implemented MR imaging techniques assess for iron content only and not for iron related diffuse fibrosis which play a role in iron related heart failure. Histopathologic studies indicate that patients with iron overload have diffuse interstitial fibrosis. Quantitative MR techniques have shown that patients with various cardiomyopathies demonstrate diffuse myocardial fibrosis and that these changes correlate with changes in cardiac function. The investigators propose that quantitative cardiac MRI for assessment of diffuse myocardial fibrosis can further improve our ability to detect early damage to the myocardium and prevent morbidity and mortality from cardiac iron overload. Detection of fibrosis in patients with thalassemia may allow for earlier identification of cardiomyopathy when compared to other techniques in clinical use including T2* analysis. Identification of fibrosis could affect patient management as it would allow for tailoring of iron chelation therapy and may lead to better understanding of the disease processes contributing to heart failure and arrhythmia in these patients.
This study will determine the feasibility of the novel Indocyanine Green (ICG) fluorescence localization technique with a Laser fluorescence thoracoscope system. The primary objective of this study is to prove the validity and safety of our novel fluorescent localization method with utilized ICG and novel near infra-red fluorescence videoscope system.
Narrowing of the aortic valve in the heart, known as severe aortic stenosis, can impede blood delivery and is associated with poor quality of life and death. In the elderly with considerable medical burden, a relatively new non-invasive valve replacement technique called Transcatheter Aortic Valve Implantation (TAVI) can be used instead of open-heart surgery. However, long term changes in cognition after TAVI remain unclear and previous studies have suggested an increased risk of cognitive decline in patients following the surgical procedure. In this pilot study, the investigators will characterize changes in cognition, physical capacity, overall quality of life and neuropsychiatric symptoms (depression and apathy) over 6 months after TAVI.
The rates of sedentary activity are increasing. Studies have shown that time spent on doing sedentary activities is an independent risk factor for cardiovascular disease. Prior studies have shown that interrupting inactivity improved the body's handling of blood glucose and gene expression. The investigators plan to explore this further by examining the effects of interrupting 4 hours of inactivity with 2 minutes of moderate intensity exercise every 20 minutes on the following metabolic parameters: blood pressure, cortisol, C-Reactive Protein, glucose and insulin levels.
The objective of this clinical study is to investigate whether the NeuroSENSE is an adequate monitor of hypnotic depth-of-anesthesia (DOA). Therefore, this study will investigate whether the information provided by the NeuroSENSE Monitor can help in assessing the hypnotic effect of anesthetics in adult patients undergoing general anesthesia.
This is a randomized, multicenter, open-label, phase 2 study of the SINE compound, selinexor given orally versus specified investigator choices (one of three potential salvage therapies). Participants age ≥ 60 years with relapsed or refractory AML of any type except for AML M3, after one prior therapy only, who have never undergone and who are not currently eligible for stem cell transplantation and are currently deemed unfit for intensive chemotherapy.
A study to evaluate the efficacy and safety of apremilast (CC-10004) in subjects with moderate to severe atopic dermatitis
The purpose of this cross over pilot study is to investigate the urinary catabolites of Proanthocyanidines (PACs) as biomarkers of cranberry extracts in healthy young women.
Study Purpose: The purpose of this clinical trial is to determine if extended-release quetiapine in a dose of 300 mg daily is tolerable to people with relapsing remitting and progressive MS. The investigators will also determine if the investigators can increase the dose up to 300 mg daily within 3 days in people with relapsing remitting MS and within 2 weeks in people with progressive MS. The investigators will determine if at least two thirds of study participants tolerate the drug well enough to continue it for 4 weeks. Tolerance will be determined separately for people with relapsing remitting and progressive MS. People with progressive MS may be less tolerant of side effects because of greater underlying brain injury from MS. Alternatively, people with progressive MS may gain more benefit from the improved sleep that usually occurs with use of quetiapine or they may be more willing to tolerate some side effects. This clinical trial will determine the maximally tolerated dose for future trials of this drug. The number of participants in this study will depend on the tolerability at each dose tested. A maximum of 18 people with relapsing remitting MS and 18 people with primary or secondary progressive MS will be included. Study Design: The cohort expansion design (3+3) is used to determine toxicity-based dosing. This design is used in oncology phase I trials as it is guided by patient safety and minimizes the number of participants exposed to toxicity (Ivy et al. 2010). Maximum toxicity is defined as 33% or less. In this model, three patients will comprise the initial cohort. In the absence of DLT treatment may be escalated to the next higher dose in the next group of three patients. However, if one of three patients reaches DLT the cohort is expanded to six patients to verify that the toxicity rate has not exceeded or reached 33%. When the toxicity rate exceeds or reaches 33% in a cohort, this dose is deemed the maximum administered dose and a lower dose will be used in the next group of three patients. Patients with RRMS and progressive MS will be evaluated in separate groups using different dose schedules.
Normal aging is associated with decline in some aspects of memory, and this can be a risk factor for reductions in everyday functioning. The Baycrest Memory and Aging Program teaches positive adaptation to age-related memory changes, including strategies for minimizing the everyday impact of normal memory change and positive lifestyle change to maximize brain health. Prior research has shown that the Memory and Aging program is effective in increasing participants' knowledge about memory, use of memory strategies, and confidence in memory function, as well as adoption of healthier lifestyle practices and reduction in intention to use unneeded health care resources. Although not one of the stated goals of the program, informal feedback from participants suggests that the educational content and skills training in the Memory and Aging Program has led some participants to change behaviours in ways that lead to significant improvements in their everyday functioning. For example, graduating participants often volunteer examples of how they have applied what they have learned to succeed in everyday memory tasks such as learning a new name or keeping track of future plans. Based on this participant feedback, it is hypothesized that the knowledge, skills, and confidence gained by Memory and Aging Program participants may lead to positive behaviour changes that, in turn, lead to improved everyday functioning. The present study will test this hypothesis using a randomized controlled pretest-posttest design.
