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.
Musculoskeletal deformities of the foot and abnormal biomechanics can create areas of high pressure over bony prominences on the plantar aspect of the foot and often lead to the formation of calluses and corns. Calluses and corns are reported to be the most prevalent foot conditions affecting peoples' lifestyles due to pain and disability. Redistribution of plantar pressure away from areas of high pressure offloading using felt pads to treat corns and calluses is a common practice in chiropody. A more comprehensive understanding of how rapidly the felt pads compress and become less effective in offloading pressure is needed to design better treatment plans to manage calluses and corns and improve patients' quality of life. The objectives of this study are: 1) develop a guideline which informs, at what duration (number of weeks) the semi compressed felt (SCF) Plantar Metatarsal Pad (PMP) should be replaced to manage plantar forefoot callus; 2) Test the guideline by replacing the SCF padding at the determined time interval. The study will be conducted at the Michener Chiropody Clinic at the Michener Institute of Education at UHN. In order to address patient selection bias, the investigators will be recruiting the first 25-40 participants presenting with forefoot callus who meet the inclusion criteria and consent to participate in the study. An exploratory, descriptive and analytic repeated measures study design will be used to address our research questions. The descriptive approach will provide insight into the nature of change over time in the dependent variables, pain and pressure, and an analytic approach will enable further insight into the relationship between those variables. The quantitative metrics used are average plantar pressure at the callus site, as well as self-reported pain using a Visual-Analog Scale (VAS). Results from the first phase will inform the development of the guideline for pad replacement, which in turn will be tested in the next phase of the study.
Within our institution, the principal investigator have acquired expertise in endorectal brachytherapy, a localized treatment for colorectal cancer. Until now a modality which uses an endorectal applicator has been used, which has certain limitations. In the context of this study, a new applicator will be used which is already approved by Health Canada for endorectal brachytherapy, thereby improving the participant's quality of life and optimizing treatment time.
A Phase 1, first-in-human, monotherapy and combination dose escalation and expansion study of SRF617.
Obstructive sleep apnea (OSA), which causes abnormal pauses in breathing during sleep, is common in patients with vascular cognitive impairment (VCI) and Alzheimer's disease (AD), and exacerbates the cognitive deficits seen in these conditions. OSA is typically treated with continuous positive airway pressure (CPAP), which has been shown to improve cognition in VCI and slow cognitive decline in AD. Despite the need to identify OSA in patients with VCI/AD, these patients often do not undergo testing for OSA. One major barrier is that in-laboratory polysomnography (iPSG), the current standard for diagnosing OSA, is inconvenient for patients with VCI/AD who may be reliant on others for care or require familiar sleep environments. A convenient and cheaper alternative to iPSG is home sleep apnea testing (HSAT), which has been validated against iPSG to diagnose OSA and has proven feasible for use in VCI/AD. Our primary objective is to determine whether the use of HSAT is superior to iPSG in terms of the proportion of patients who complete sleep testing by 6 months post-randomization. We will also investigate cost-effectiveness, patient satisfaction, proportion of patients treated with CPAP, changes in cognition, mood, sleep-related and functional outcomes between HSAT and iPSG at 6 months.
This study aims to investigate the feasibility and effectiveness of a remotely delivered psychological intervention for youth with cSLE. This intervention aims to teach participants skills in order to cope with fatigue, pain, and depressive symptoms--symptoms that commonly affect adolescents and young adults with lupus.
This study evaluates two Internet-delivered cognitive behavioural therapy (ICBT) interventions: one for symptoms of posttraumatic stress disorder (PTSD) and one for symptoms of anxiety, depression, and PTSD. Both interventions have been tailored for Canadian public safety personnel (PSP). Outcomes of interest include preference for disorder-specific or transdiagnostic care, engagement with the interventions, changes in symptoms and functioning, and strengths and limitations of implementing ICBT with Canadian PSP.
This phase II single-armed study will examine the clinical utility of retreating patients with osimertinib, in the third-line, following first-line treatment with osimertinib and second-line treatment with platinum and pemetrexed chemotherapy. The current standard of care for first-line Epidermal Growth Factor Receptor (EGFR) mutated Advanced Non-Small Cell Lung Cancer (aNSCLC) is osimertinib, followed by cytotoxic chemotherapy. The repeat of osimertinib following previous treatment failure is investigational, although supported by scientific rationale. The dosing and scheduling of osimertinib follows its use in approved settings. The investigators examine its tolerability and efficacy in this setting to ensure osimertinib is a safe third-line option for patients with Epidermal Growth Factor Receptor mutated (EGFR+) Advanced Non-Small Cell Lung Cancer(aNSCLC).
Contagious disease outbreaks, such as the coronavirus disease 2019 (COVID-19) outbreak, and associated restrictions to prevent spread can lead to negative psychological outcomes, including loneliness, depression, and anxiety, particularly in vulnerable populations at risk due to existing medical conditions. To date, no randomized controlled trials have tested interventions to reduce mental health consequences of contagious disease outbreaks. Systemic sclerosis (SSc; scleroderma) is a rare, chronic, autoimmune disease characterized by vasculopathy and excessive collagen production. Systemic Sclerosis can affect multiple organ systems, including the skin, lungs, gastrointestinal tract, and heart. Many people with scleroderma are at risk of serious complications from COVID-19 if infected due to lung involvement (> 40% have interstitial lung disease) and common use of immunosuppressant drugs. The objective of The Scleroderma Patient-centered Intervention Network COVID-19 Home-isolation Activities Together (SPIN-CHAT) Trial is to evaluate a videoconference-based intervention designed to improve symptoms of anxiety and other mental health outcomes among individuals with systemic sclerosis at risk of poor mental health during the COVID-19 pandemic. The trial is a pragmatic randomized controlled trial that will be conducted using an existing cohort of systemic sclerosis patients. We will use a partially nested design to reflect dependence between individuals in training groups but not in the waitlist control. The SPIN-CHAT Program includes activity engagement, education on strategies to support mental health, and mutual participant support.
The purpose of this study is to determine whether the use of hydrochlorothiazide is associated with an increased risk of skin cancer compared with the use of angiotensin-converting enzyme (ACE) inhibitors. More specifically, the investigators will assess the risk of non-melanoma and melanoma skin cancer. The investigators hypothesize that the use of hydrochlorothiazide is associated with an increased risk of skin cancer compared with ACE inhibitors. The investigators will carry out separate population-based cohort studies using administrative health databases from seven Canadian provinces and the United States. The study cohort will be defined by the initiation of hydrochlorothiazide or an ACE inhibitor, with follow-up until an incident diagnosis of non-melanoma or melanoma skin cancer. The results from the separate sites will be combined to provide an overall assessment of the risk of non-melanoma and melanoma skin cancer in users of hydrochlorothiazide.
This is a pilot, open, prospective, non-randomized study to evaluate the safety and efficacy of switches from etravirine to doravirine, in experienced patients with multiple class resistance including NNRTI resistance. The other ARV medication (protease inhibitor, entry inhibitor and integrase inhibitor) that some patients receive, in addition to the NRTI and NNRTI, will not be changed. The study will be performed only on two sites
