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.
C3731003 is a pivotal Phase 3 study to evaluate the clinical efficacy and safety of a single IV infusion of PF-07055480 / giroctocogene fitelparvovec (Recombinant AAV2/6 Human Factor VIII Gene Therapy) in adult male participants with moderately severe or severe hemophilia A (FVIII:C≤1%) for the study duration of 5 years. The study will enroll eligible participants who have been followed on routine prophylaxis with FVIII products in the Lead-In study C0371004.
Surgery is the first choice of treatment for early-stage primary pulmonary malignancies, but up to 15% of all patients, and 33% of patients greater than 75 years of age, are not surgical candidate's due to locally advanced disease, poor cardiopulmonary reserve and significant medical co-morbidities. Some patients are also unwilling to undergo surgery. This has prompted the development of alternatives to surgery so that local control of unresectable tumors can be achieved. Stereotactic body radiation therapy (SBRT) is currently an alternative therapy for these patients with 3-year survival rates of between 42 and 60%. SBRT has excellent local control rates and a favorable toxicity profile relative to other surgical and non-surgical therapies. Radiation pneumonitis (RP), amongst others, is one of the major toxicities which can limit the maximal radiation dose that can be safely delivered to thoracic tumors. Reported rates of SBRT induced RP requiring clinical intervention range from 0% to 29% and life-threatening toxicities have been reported in up to 12% of cases in various studies. The potential for toxicities from SBRT could limit the number of times a patient could be treated with SBRT for residual, recurrent or new pulmonary lesions over time. Following the first report of thermal ablation for lung malignancies in 2000, this modality has been used to treat primary and secondary malignancies and has emerged as an effective, low-cost, safe and repeatable alternative to SBRT for local tumour control. The most widely practised technique is radiofrequency ablation (RFA). Microwave ablation (MWA) is a relatively new therapy and offers all the advantages of RFA, but with significant additional advantages 3. These include reduced procedure times, lower complication rates, increased ablative temperatures, improved propagation of thermal energy particularly in the lung, improved efficacy in lesions that are in close proximity to blood vessels due to reduced heat-sink effect, and less procedure associated pain 2,3. Using high energy MWA to treat 87 pulmonary tumors, Egashira et al achieved a primary technical success rate of 94% and technique effectiveness of 98% at a median of 15 months. MWA is performed by Interventional Radiologists using CT guidance. The treatment is performed under general anaesthesia and is repeatable. Multiple lesions can be ablated in one treatment session. Patients can potentially be discharged the same day of treatment, if there are no adverse events. MWA is a relatively new treatment option that could be considered in situations where the patient is not a candidate for further treatment with surgery, SBRT or chemotherapy, or the patient declines the recommended standard available treatments. Objectives for Phase I: The primary objective for Phase I of this study will be to demonstrate the Safety of MWA performed for treatment of lung malignancy in patients not suitable for surgery, chemotherapy or SBRT. Primary objective (Safety): to determine the proportion of patients experiencing local adverse events at one week definitively related to the mwa procedure. Secondary objective (Feasibility): To determine the proportion of patients in whom technical success of MWA was achieved by assessing completion of ablation on CT at the time of the procedure, indicated by replacement of tumor by ground glass change (including a 5mm ablation zone in normal surrounding lung parenchyma). Objectives for Phase II Primary objective (Efficacy): To demonstrate efficacy by measuring the proportion of patients demonstrating absence of residual tumor on follow up CT at 1 month after MWA. Secondary objective: To determine the proportion of patients needing re-treatment for recurrent tumor at 1 month post MWA.
A dynamic analytical tool is being implemented to monitor the health, psychosocial and economic impacts of the COVID-19 pandemic as the crisis unfolds. A longitudinal survey is distributed via a network of hospitals, provincial/national organizations and web platforms. The survey information can be linked to provincial health administrative data and metrics derived from social media activity based on artificial intelligence methods. Targeted questions are included for critical populations such as healthcare workers and people with chronic illnesses.
Repetitive transcranial magnetic stimulation (rTMS) uses a magnetic field to non-invasively induce electrical function within the brain. Stimulation allows brain cells to change the way that they adapt and communicate with each other, known as 'synaptic plasticity'. It is thought that alterations in these adaptive brain changes underlie the ability of rTMS to treat mental illnesses like depression. rTMS is a Health Canada approved treatment for depression, however, 2/3rds of people fail to show meaningful improvement. This highlights the need for more effective therapeutic means. The purpose of the present study is to augment the therapeutic abilities of rTMS through the conjunctive use of a medication that also increases synaptic plasticity. We will pair TMS with an electroencephalograph (EEG) to measure activity dependent changes in the frontal cortex following rTMS.
Preclinical mobility limitations (PCML) manifest early in the process of declining mobility, and are not typically identified or acted upon by clinicians. These mobility limitations manifest as changes in how daily tasks such as walking are performed (slower speed, lower endurance). Persons in the PCML stage are at increased risk for the onset of disability and chronic disease. Persistent deterioration in mobility is a predictor of mortality and has been reported even in the absence of changes in activities of daily living over a two-year period. Further, older persons with mobility limitations, including reduced gait speed, are at risk for falls. These cumulative transitions of a person's life-long mobility form their mobility trajectory and preventing mobility decline at an early stage along this trajectory is the focus of this research initiative. This study will evaluate a novel intervention, STEPPING-UP, for improving walking ability in persons with PCML.
This study will examine the feasibility of conducting an online Randomized Controlled Trial (RCT) in frontline hospital and long term care healthcare staff in managing COVID-19 patients in London, ON. The study will randomize participants to Sudarshan Kriya Yoga (SKY) or a Health Enhancement Program (HEP).
The purpose of this pivotal study is to determine if intravenous Rezafungin is efficacious and safe in the prevention of invasive fungal diseases when compared to the standard antimicrobial regimen.
This study aims at investigating handwashing behavior during COVID-19 pandemic. It was hypothesized that social-cognitive and emotional predictors as well as COVID-19 morbidity and mortality rates within the country would be associated with handwashing behavior in the general population of adults in 14 countries.
A multi-site, multi-modality prospective observational clinical outcomes study focussed on the development of phenotype-dirven risk prediction modelling in patients with known or suspected cardiovascular disease.
The major purpose of this study is to establish the use of daily step counts as inexpensive, easy to measure marker for frailty and sarcopenia in an inpatient population of older adults.
