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.
Biopsies are routinely taken during endoscopy and colonoscopy in order to facilitate histological analysis of various disease processes. The current practice of obtaining biopsies involves taking a maximum of two biopsies at a single time (ie. with a single pass). When investigating certain diseases, such as celiac disease, there is a need to obtain several biopsies (sometimes greater than 6) and the current practice of taking one to two biopsies at a time can lengthen endoscopy time. This study investigates a new approved multiple bite forceps that has the ability to retrieve six biopsies during a single pass which could reduce endoscopy time and improve diagnostic yield. This study will assess the histological quality of multiple biopsies when taken with the multiple bite forceps compared to the standard double bite forceps. This multiple bite forcep is approved for clinical use in Canada.
Diet can alter blood ketone levels and this in turn may affect exercise capacity. This study will determine if the acute ingestion of a ketone supplement alters cycling time trial performance. Participants will perform two trials in a randomized order. Each trial will involve a 20-minute bout of cycling on a stationary ergometer. Participants will ingest either a ketone supplement or a taste-matched placebo drink prior to exercise. Blood samples will be obtained to assess selected metabolic responses. This study will provide information regarding the effect of ketone supplementation on exercise responses.
VIDO has developed a vaccine called COVAC-2. The COVAC-2 study vaccine contains a portion of the SARS-CoV-2 spike protein, called S1. The spike protein is the part of the virus that is responsible for attaching to the surface of host cells. COVAC-2 contains a SWE adjuvant. An adjuvant is a compound that is added to a vaccine to help the vaccine produce a better immune response. The SWE adjuvant is similar to another adjuvant, MF59, that is found in influenza vaccines and MF59 containing vaccines have been given to millions of people around the world. The vaccine is expected to stimulate the body to make antibodies against the S1 protein. The antibodies will recognize the viral spike protein if the body is exposed to the virus and prevent severe COVID-19 illness. In animal studies, the immune response generated by the COVAC-2 vaccine was able to protect the vaccinated animals against a severe SARS-CoV-2 infection. This is a Phase 1/2, placebo-controlled, observer-blind, age-stratified randomized, multicenter study to access the safety and immunogenicity of two dosing levels (10 and 25 µg S1 protein tested in parallel) administered once in healthy adults ≥18 of age who have received 2 doses of an authorized COVID-19 vaccine at least 6 months earlier. The study will also include an open-label exploratory study arm to evaluate safety and immunogenicity of a single COVAC-2 dose in previously SARS-CoV-2-infected individuals (Phase 2 only).
This is a multi-centre single cohort trial of patients undergoing cruciate-retaining total knee arthroplasty with the Advance Porous fixed bearing tibial baseplate and compatible femoral, patellar, and bearing components.
Background Effective management of spasticity, a debilitating and challenging condition afflicting many recovering from and living with neurological conditions, may reduce long term consequences such as limb contracture, skin breakdown, compromised mobility, caregiver burden and discomfort. In rehabilitation, spasticity represents a significant barrier to successful rehabilitation outcomes. Effective spasticity management can increases the length of individual functional status, reduces equipment/care needs, hospital admissions and extends the time people can stay safely at home, which would represent an economic benefit to the health system. Extra-corporeal Shock Wave Therapy (ESWT), an intense short energy wave delivered directly at the region of affected muscles has, in past randomized controlled studies, demonstrated positive outcomes for this population (spastic stroke population, TBI), on its own and as an adjunct to current modalities. In fact, one retrospective observational study demonstrated an increased efficacy of Toxin botulinum at 1 month when combined with ESWT. Where existing treatment options may be limited by coverage, access to delivery, complications and side effects, ESWT represents a potential to be a safe, low cost, efficacious alternative that can be administered by any trained clinician. Aims The aims of this pilot study will be to explore the hypothesis that adding ESWT to Botulinum Neurotoxin A (BoNTA) in spasticity post-stroke (TBI)will demonstrate greater clinical and patient reported outcomes compared to standard treatment with BoNTA alone, a comparison only once previously studied. Methods Incorporating randomization and placebo control (n= 20 in each arm), this patient-centric study will examine treatment goals and holistic perception of benefit after the treatment experience. We will use patient reported outcomes at baseline and at defined intervals after intervention. We will test our hypothesis using clinical and patient reported scales, such as the patient reported numeric rating scale (NRS) and goniometric range for spasticity as our primary outcome in conjunction with measures of muscle stiffness, quality of life, feasibility and acceptability of the protocol to help inform future study direction.
Neonatal Abstinence Syndrome (NAS), is a common and costly problem in Alberta that affects approximately 250 babies per year exposed to drugs during pregnancy. Unfortunately, this has become more common in the last 10 years. Babies with NAS can be very difficult to care for with poor feeding, diarrhea, and extreme irritability. These babies often receive specialized care and medications in the Neonatal Intensive Care Unit (NICU), which leads to separation of mothers and babies at a time when it is most important that they be together. This separation is traumatic for families and expensive for the health and foster care systems, as babies often end up being cared for by governmental agencies. Recent research has shown that keeping mothers and babies together in a quiet, supportive environment in hospital, called 'rooming in', leads to a decreased need for NICU admission, decreased amount of time spent in the NICU, increased rates of breastfeeding, and an increase in babies going home with their mothers. This project will systematically introduce a program of 'rooming-in' to hospitals in Alberta to determine if the investigators can improve NAS care provided to babies and mothers. The goal is to decrease NICU admission and length of stay, increase the number of babies going home with mothers, increase breastfeeding rates, and increase the number of women enrolled in supportive programs for substance use. The investigators will also determine if this rooming-in model of care decreases health and societal costs associated with caring for babies with NAS.
This is a phase 2, randomized, double-blinded, placebo-controlled, parallel-group, multicenter trial to evaluate the safety and efficacy of 2 dose regimens of ARGX-117 versus placebo, in participants with MMN previously stabilized with IVIg (intravenous immunoglobulin).
Psoriatic Arthritis (PsA) is a type of auto-immune condition that affects roughly 90,000 Canadians. Patients with PsA often experience joint pain, skin problems, and issues with mobility that negatively impact their quality of life. Compared to the general population, patients with PsA are at a higher risk of having obesity (excess body weight). Although there is no cure for PsA, medications can be helpful for symptoms, and weight loss can provide an added benefit to the effectiveness of medications. Behavioral weight loss treatment (BWLT) is a proven way to lose weight and keep it off. BWLT usually includes individual or group sessions with a health professional to learn strategies and tools to change behaviours and thoughts in order to support weight loss. However, few studies have designed a BWLT with the unique needs of patients with PsA in mind. Before testing new treatments for chronic disease in large, expensive studies, it is important to do smaller-scale research to make sure that a future large study will be successful. In line with this, the objective of our study is to test the feasibility of a future, large study of a BWLT for patients with PsA and obesity. In other words, our small feasibility study will investigate how convenient, reasonable, and acceptable the future study's procedures are, using a small group of people with PsA and obesity. People who have PsA and obesity will take either a special BWLT program, or receive usual care for PsA from a community-based rheumatologist. Those in the BWLT group will complete 16 online group sessions to help them learn cognitive and behavioral changes to help improve their health and manage weight. After 24 weeks, we will determine study completion rates, examine patient satisfaction, and assess whether the BWLT was provided to people as-designed. We believe this research will help with efforts to provide more effective treatments to patients with PsA to help them lose weight and improve their quality of life through reduced pain and symptoms.
Ebstein anomaly and tricuspid valve dysplasia (EA/TVD) are rare congenital tricuspid valve malformations that carry among the highest mortality of all congenital heart disease diagnosed in utero. Despite the high mortality associated with severe EA/TVD in the fetus, it has only been studied retrospectively. By prospectively enrolling a cohort across multiple centers, many questions may be answered in the perinatal period and beyond. The registry will allow us to understand perinatal and postnatal decision-making in this complex group of patients across centers.
In 2019, the Enhanced Recovery After Surgery (ERAS) Society published recommendations for perioperative care in cardiac surgery. ERAS recommendations included 22 perioperative interventions that may be part of any cardiac Enhanced Recovery Program (ERP). Since that publication, additional perioperative interventions were reported and may be added to a cardiac ERP. Studies on cardiac ERPs report variable benefits on postoperative recovery including lower pain scores, lower opioid consumption and related side effects, shorter intensive care unit and hospital discharge times. At the "Centre Hospitalier de l'Université de Montréal" (CHUM), although most care takers are aware of ERAS recommendations for cardiac surgery patients, adherence to these recommendations is heterogeneous and a cardiac ERP was never implemented.
