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.
A study to collect survival data on patients previously enrolled in Abraxane pancreatic cancer study CA046.
The purpose of this randomized, double-blind study is to investigate the efficacy and safety of mepolizumab (300 milligram [mg] administered subcutaneously [SC] every 4 weeks) compared with placebo over a 52-week study treatment period in subjects with relapsing or refractory Eosinophilic Granulomatosis with Polyangiitis (EGPA) receiving standard of care therapy including background corticosteroid therapy with or without immunosuppressive therapy. During the treatment period, in accordance with standard of care, corticosteroid dose will be tapered. The key outcomes in the study focus on evaluation of clinical remission, defined as Birmingham Vasculitis Activity Score (BVAS)=0 with a corticosteroid dose of <=4 mg/day prednisolone/prednisone, reduction in disease relapse and reduction in corticosteroid requirement.
The purpose of this study is to assess whether food ingredient(s) affect glycemic responses.
The current standard of care for rehabilitation of patients with aphasia after stroke is conventional speech and language therapy (SLT). Due to economic realities on most stroke units, SLT can often not be given with optimal intensity in the first weeks after the stroke. Developing new adjuvant therapies which may render SLT sessions more effective is thus one approach to improve rehabilitation outcome. Recent functional imaging studies in post-stroke aphasia have shown that the recruitment of brain regions in the unaffected hemisphere seems to be an inferior strategy for recovery of language function as compared to re-activation of brain regions in the vicinity of the infarct. Non-invasive brain stimulation techniques, such as repetitive transcranial magnetic stimulation (rTMS) or transcranial direct current stimulation (tDCS) are new methods to modulate brain activity. Evidence from our own feasibility study in sub-acute stroke suggests that these new techniques, when applied in conjunction with conventional SLT, may help to normalize brain activation patterns and might yield better rehabilitation outcome than SLT alone. With NORTHSTAR, we propose a multicenter proof-of-concept study to investigate the safety, feasibility and efficacy of these new non-invasive brain stimulation methods as adjuvant therapies for subacute post-stroke aphasia. Our goal is to determine the most effective brain stimulation modality to decrease inhibition onto the left side of the brain. We will assess if a combination of brain stimulation and speech and language therapy will improve language recovery. We will quantify language recovery (expressive and comprehensive skills) using specific tests, commonly used by speech and language therapists. We will invite patients recently admitted to the stroke unit of the study centers to participate in our research project. Once patients consent to our study we will randomly assign them to one of three experimental groups. For 12 days, all groups of patients will be setup with brain stimulation during their usual rehabilitation sessions. Two of those groups (treatment groups) will each receive a different type of brain stimulation (rTMS and tDCS), in the third group, patients will not receive real stimulation (placebo group). By comparing the extent of aphasia recovery between groups, we will determine the benefits attributable to brain stimulation relative to SLT alone.
Stereotactic radiotherapy (SRT) is a newer type of focused radiation therapy that precisely and accurately delivers high dose radiation to a tumour, while sparing much of the nearby normal organs. The use of stereotactic radiotherapy results in high rates of tumour destruction with minimal side effects which are very well tolerated. Often stereotactic radiotherapy has been used to try to cure patients who have an early stage cancer which has not spread, but there is less experience with using it in patients with cancer which has spread. The purpose of this study is to measure how well stereotactic radiotherapy can destroy kidney cancer tumours which are no longer being controlled by Sunitinib and to measure how much longer such an approach will allow patients to stay on Sunitinib before needing to switch to another medication. Stereotactic radiotherapy will be used to treat only the growing tumours and then patients will continue with Sunitinib.
To compare radiographic and clinical outcomes and survival of mineral trioxide aggregate/ferric sulfate (MTA/FS) pulpotomy and root canal therapy (RCT) in carious vital primary maxillary incisors.
This is a multicenter, randomized, double-blind, placebo-controlled, parallel-group study in overweight and obese subjects with cardiovascular (CV) disease and/or multiple CV risk factors.
The purpose of this study is to evaluate the quality and prognostic ability of low dose 99mTc-tetrofosmin Myocardial Perfusion SPECT Imaging.
The purpose of this study is to determine 1. if it is practical to treat moderately to severely brain injured patients who have problems with their balance and mobility in a group "boot camp" (3 days a week, 6 hours/day for 4 weeks) exercise class. 2. If they show improvements compared to 4 weeks of not receiving this treatment 3. If electronic daily monitoring of their center of foot pressure during a standardized balance task will allow us to see small changes in ability. A baseline assessment of all outcome measures will be performed. This will be repeated 4 weeks later. The intervention will be delivered (4 weeks) and a follow up assessment of all outcome measures will be performed one week later. A follow up of the Primary outcome measure, the PART-O participation questionnaire will be done 12 weeks later. Participants will attend group therapy consisting of a variety of exercises designed specifically to target balance and mobility deficits and based on the concept that through Repetitive Functional Task Practice (RFTP), recovery of function can occur as the result of neural adaptation. Exercises will be both individualized (delivered in a circuit) and group activities. Supervision and guidance will be provided by a registered Physical Therapist and a Rehabilitation Assistant. During the intervention, the amount and type of RFTP, any adverse events, and any need for extra staff will be recorded on a daily basis. As well, a standardized individualized task will be performed with center of foot pressure recording on a daily basis. Analysis: changes in outcome measures immediately after the non-intervention compared to the after the intervention period will be statistically determined to estimate efficacy of this treatment model. Descriptive measures of RFTP time/day, staffing levels/day and adverse events will be used to support feasibility and safety of this model.
Knee osteoarthritis (OA) is a costly health condition affecting more than 10% of Canadian adults. Excessive and unbalanced loads passing through the knee joint have been implicated in the progression of OA. Typical conservative treatment of OA has focused on increasing daily activity, without consideration for the underlying joint loading. This study aims to compare a 4-month walking program that aims to increase the angle of the foot (toe-out angle) during walking - a measure shown to reduce joint loading and OA disease progression - while increasing walking time/distance, with a standard walking program that aims to increase walking time/distance. It is predicted that the walking program focusing on increasing toe-out will provide greater reductions in self-reported knee pain and a greater reduction in unfavorable knee joint loading.
