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.
Capsule endoscopy is a non-invasive way to examine the small bowel, but its yield is limited by the battery life. In 20% of cases, the recording stops before the entire length of small bowel is examined. Capsule transit speed is dependent on bowel motility. When we eat, the brain sends signal to the bowel to speed up motility. In this study the investigators wish to determine if chewing bacon (sham feeding) can trick the brain to speed up bowel motility and improve the rate of complete small bowel examination.
Dexmedetomidine is a sedative drug that is commonly used to improve calmness and reduce pain in children waking up after surgery. Some of the side effects of dexmedetomidine, such as a potential change in how the heart muscles contract and changes in blood sugar and potassium levels, are poorly understood. The current study aims to examine these changes directly in healthy children undergoing elective surgery by measuring the heart beats (with an electrocardiogram) and blood sugar and potassium at specific times before and after dexmedetomidine is given. The investigators aim to establish a better understanding of this drug's safety profile.
This study is a Phase III, randomised, open label, multi-centre study assessing the efficacy and safety of MEDI4736 (durvalumab) versus Standard of Care in NSCLC patients with PD-L1 positive tumours and the combination of MEDI4736 (durvalumab) plus tremelimumab (MEDI4736+treme) versus Standard of Care in NSCLC patients with PD-L1-negative tumours in the treatment of male and female patients with locally advanced or metastatic NSCLC (Stage IIIB-IV), who have received at least 2 prior systemic treatment regimens including 1 platinum-based chemotherapy regimen for NSCLC. Patients with known EGFR (Epidermal growth factor receptor) tyrosine kinase (TK) activating mutations and anaplastic lymphoma kinase (ALK) rearrangements are not eligible for the study (prospective testing is not planned within this study). The Standard of Care options are: an EGFR tyrosine kinase inhibitor (erlotinib [TARCEVA®]), gemcitabine or vinorelbine (NAVELBINE®)
From a rehabilitation point of view, while several approaches exist to retrain runners with PFPS, it is not clear which one is most effective, or why. The goals of this randomised-controlled trial are: 1) to compare the effectiveness of three rehabilitation programs on pain and functional limitations of runners with PFPS and 2) to explain why the programs are effective or not based on laboratory analyses. After baseline evaluation, runners will be randomly assigned to one of three treatment groups, each with a specific 8-week rehabilitation program aimed at addressing the efficiency of a specific type of retraining. These groups are: 1) Control; 2) muscle recruitment; 3) reducing knee loading during running. The investigators hypothesis is that the intervention targeting a reduction in knee loading will be significantly more effective in reducing symptoms and improving function of runners with patellofemoral pain syndrome.
A Prospective Randomized Trial Comparing Standard Ligament Reconstruction Tendon Interposition (LRTI) VS Ligament Reconstruction Tendon Interposition (LRTI) with an interference screw for thumb carpometacarpal arthritis
This study will investigate how repetitive transcranial magnetic stimulation delivered as a protocol called 'continuous theta-burst stimulation (cTBS)' alters motor output and force control to a muscle in the forearm and touch perception in individuals with chronic, incomplete spinal cord injury. CTBS is a non-invasive technique that involved repetitive delivery of transcranial magnetic stimulation at a frequency of 30 Hz over the arm representation in the primary motor or sensory cortex. The purpose of this study is to determine whether cTBS is an effective intervention to increase motor output to a muscle and increase force control of that muscle and also improve the sense of touch.
Alzheimer's disease (AD) is commonly associated with behavioural changes such as agitation. Severe agitation is important to treat because it not only increases progression of AD and physical health problems (increased falls and weight loss), but it also decreases quality of life and increases caregiver stress. Currently prescribed treatments (i.e., antipsychotics) for agitation in AD do not work in everybody and when they do work the effect is small and they increase the risk of harmful side effects, including death. As a result, there is an urgent need for safer medication options. The cannabinoid nabilone can now be prescribed in capsule form for appetite and pain killing effects. Nabilone's calming effects may benefit those with agitation, and help the weight loss and untreated pain frequently associated with agitation. Through a clinical trial, the investigators hope identify the benefits of nabilone in the treatment of agitation in AD. The investigators objective is to determine whether nabilone is an efficacious and safe treatment for agitation, as well as having benefits for pain, weight and behavioural symptoms. This will be a 14 week clinical trial (participants take nabilone for 6 weeks, placebo for 6 weeks (order randomized) with 1 week between treatments). The investigators will assess and compare agitation, weight, pain, memory, behaviour and safety. Nabilone is a new class of medication that may be a safe and effective treatment for agitation in AD, with added benefits on appetite and pain. Reducing these symptoms would increase quality-of-life and reduce caregiver stress.
The EEU has proven effective in multiple studies evaluating various aspects of seasonal allergic rhinitis. All previous EEU clinical trials have utilized ragweed or grass pollen as the allergen of choice for dispersal, due to the local population, but many emerging treatments for allergic rhinitis are allergen specific, thus it is desirable to expand the repertoire of pollen selection for use in the EEU. Ragweed, grass and birch pollen have differing appearances and sizes but essentially, both have characteristics which promote the ability to keep the pollen grains suspended and hence, the ability to maintain proper concentrations within the EEU. Preliminary validation studies conducted in the EEU, absent of human volunteers, have confirmed our ability to release, disperse and maintain birch pollen concentrations in the EEU using the existing technology. This study aims to validate the use of birch pollen on a clinical scale. By adding non- allergic participants into the EEU, the investigators hope to determine if non-allergic persons exhibit differences at baseline in their "epigenetic biomarkers" from those who have pre-existing and established allergic airways inflammation.
Chronic kidney disease is a common diagnosis in the elderly population and it is associated with significant morbidity and health care costs. The prevalence rates increase with age to about 40% for adults aged > 65 years. In the elderly population (age 65 and over), CKD is associated with a higher burden of comorbid conditions and frailty. The prevalence of frailty is higher in CKD patients with rated being double in early stages and nearly 6 times higher beyond stage 3b. Previously reported frailty mortality rates of 18% at 3 years and 47% at 7 years comparing with mortality rates in non frail individuals of 3% and 12% respectively. In this study, the investigators investigate the effect of multidisciplinary interventions upon frail elderly patients with CKD not yet on dialysis. This interventions include best medical care, nutrition, physiotherapy, and social, psychological and spiritual support.
Osteoarthritis (OA) is one of the most common forms of arthritis. It is a lasting condition in which the material that cushions the joints, called cartilage, breaks down. This causes the bones to rub against each other, causing inflammation, stiffness, pain and loss of joint movement. Currently, there are few effective treatments available for patients suffering from OA. Mesenchymal stem cells (MSCs) are cells that have the ability to self-regenerate, which means they have the ability to make copies of themselves and to turn into other kinds of cells (e.g. cartilage cells). Stem cell science shows much promise for the future treatment of osteoarthritis, but much of the research is still in the early stages. In this study, researchers want to determine the safety of MSCs that a patient can tolerate without causing side effects. This will be done by starting at a low dose of MSCs and moving on to the next higher dose level provided there are no safety concerns. Researchers will also be looking at the function of the knee over time, which may give them some insight on the usefulness of MSCs as a treatment option.
