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.
This is a feasibility study requiring only three patients to serve as a proof of concept that gadoxetate disodium (a liver specific contrast agent) can be used to improve images taken just before liver SBRT treatments. The hypothesis of this research is that if gadoxetate disodium improves image quality at the time of treatment, then it can be used for image guided radiotherapy (IGRT). Image guidance is the procedure where the 3D CT image that is used to plan a radiotherapy treatment, is aligned to a 3D image taken just before treatment. The better the alignment, the more accurate the treatment, which is crucial for high dose treatments such as SBRT. This research is important for two main reasons. First, it is much less invasive than the standard of care which involves surgically implanting markers in the liver that can move over time. The benefit to harm ratio for surgery, compared to an injection, is much more dramatic. Furthermore, not all patients are surgical candidates, and therefore in those cases radiation oncologists must prescribed a larger area to treat to ensure that none of the cancerous region is missed. The drawback to this method is the irradiation of more normal tissue than necessary, which although deemed to have a greater benefit than harm, is not ideal. Secondly, this research has strong implications in the field of radiation oncology to move towards patient oriented radiotherapy treatments. If successful, radiation treatment to the liver could be performed in less treatments because of the confidence given to radiation oncologists of the cancer location; knowing exactly the healthy liver regions to avoid.
To investigate the safety and efficacy of abatacept with steroid treatment in comparison to steroid treatment alone in up to a 28 week taper of steroid treatment to sustain remission of Giant Cell Arteritis in adults.
The purpose of this study is to assess the effectiveness of combining binocular treatment with repetitive transcranial magnetic stimulation (rTMS) in improving the vision of adults with amblyopia. This study also seeks to assess the effect of this combined treatment on cortical neural function and functional connectivity.
Compare and assess the accuracy and reliability of the InstaTemp MD® device to techniques presently in use for measuring temperature in infants and children in a Canadian clinical setting.
Breast cancer is the second most common form of cancer in women and the most frequent cause of death. Despite breast screening programs, a substantial number of women are diagnosed with cancers greater than 2 cm in size or locally advanced disease, which is best treated with neoadjuvant chemotherapy (NAC) prior to surgery. Approximately 10% of women diagnosed with breast cancer annually will have locally advanced breast cancer, defined as stage III disease, where the cancer has either spread to regional lymph nodes and/or other tissue in the area of the breast, but not to distant sites. NAC offers the advantages of downstaging the disease, potentially reducing the extent of surgery. Presently, gadolinium enhanced MRI is the standard test used to monitor disease response to chemotherapy, and demonstrates changes in tumour size and extent between pre-NAC and post-NAC. Unfortunately, changes in tumour size may occur late in treatment regimen, thus producing false-negative results on early magnetic resonance imaging (MRI). Therefore, newer imaging techniques beyond anatomical imaging are needed to identify tumours that are unresponsive to chemotherapy and potentially change treatment plan early on to avoid significant morbidity associated with prolonged chemotherapy. A novel MRI technique utilizing hyperpolarized pyruvate has the potential to detect pathophysiological response early in the treatment regimen and would therefore allow for earlier identification of nonresponders and subsequent early modification of treatment regimens, if necessary.
The purpose of our study is to determine if anatomic/kinematic total knee arthroplasties (TKAs) are superior to mechanical axis-referenced TKAs with respect to determinants of gait functionality, patient satisfaction and other objective tests of knee function as a potential indicator of long-term prosthesis outcomes. To our knowledge there has not been any literature comparing TKAs using the kinematic and mechanical axes with respect to gait analysis. A single study has compared gender-specific TKAs and found that there is no difference with respect to determinants of gait when using these prostheses (Thomsen et al, 2012), but again this study was not based on referencing off of the anatomical/kinematic axis of the knee. Our group is hoping that the small variability that may be detectable with the precision of gait analysis may be used as a predictor of future prosthesis outcome measures.
This is a quality assurance project to evaluate a therapy program offered to patients in Sleep Disorders Clinic. Group Cognitive Behavioral Therapy for Insomnia (CBT-I) is being offered to older adults. The study will consist of analyzing outcomes of a clinical program. As part of standard clinical process, patients complete measurements of sleep, daytime functioning, fatigue, quality of life, depression and anxiety symptoms before and after the treatment. The proposed study will pool and quantitatively analyze the existing clinical data. Only those program participants who consent to have their data pooled in the data analysis will be considered research subjects. Those patients who decline to have their individual data included in the analysis will continue in the therapeutic group as per usual clinical care standards. CBT-I is a gold standard treatment for people suffering from insomnia but it is difficult to access due to a shortage of trained therapists. Insomnia prevalence increases with age and is a common sleep disturbance in the elderly. Offering the group treatment can increase access and reduce healthcare costs associated with sleep problems in the elderly.
Pilot Study of Clinical Safety and Feasibility of the Neuro-Spinal ScaffoldTM for the Treatment of Complete (AIS A) Traumatic Acute Spinal Cord Injury at the C5-T1 Neurological Levels The purpose of this study is to support an expansion to support marketing applications as well as future studies.
The aim of this phase III study is to establish the efficacy and safety of P-3058 (terbinafine 10% nail solution) topically administered once weekly in patients with onychomycosis in comparison to the Vehicle in a double-blind fashion. The overall treatment period will be of 48 weeks.
This study aims to measure the cardio-respiratory physiological consequences of initiating resuscitation during placental transfusion (PT) with an intact umbilical cord in infants with congenital diaphragmatic hernia (CDH). PT, mainly via delayed cord clamping, has been shown to offer a higher circulating blood volume, less need for blood transfusion, less need for inotropes in infants. Currently infants with CDH receive immediate cord clamping (ICC) to facilitate immediate resuscitation including immediate intubation and mechanical ventilation. With the development of a resuscitation platform (iNSPiRE), resuscitative care can now be commenced from birth in infants with CDH to benefit from PT.
