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.
Patients aged 18-65 with acute demyelinating optic neuritis where treatment with high dose corticosteroids are already been chosen by the patient and the diagnosing physician will be contacted for screening and enrollment. Patients will then be randomized to receive equivalent doses of either intravenous (IV) or oral corticosteroid treatment. Optic nerve function assessments will be compared at baseline, prior to treatment, one and six months post corticosteroid treatment. This will allow for a comparison on whether the route of medication plays a role in the effectiveness of treatment with high dose corticosteroids.
Cigarette smoking rates are extremely high in persons with schizophrenia and this increases the risk of disease and death due to tobacco-related disorders. One of the features of schizophrenia is reduced cognitive abilities, such as poor attention and memory. It is thought that people with schizophrenia smoke cigarettes to reduce these cognitive problems, as nicotine can improve cognitive function in these people. When people with schizophrenia stop smoking it causes further cognitive difficulties, which makes quitting harder for them compared to people without schizophrenia. A method called repetitive transcranial magnetic stimulation (rTMS) allows clinicians to give repeated magnetic pulses through the scalp to cause changes in brain activity and behaviour. rTMS can improve cognitive function in people with schizophrenia. Studies have also shown that rTMS can reduce tobacco craving and consumption of cigarettes. Therefore, we believe that rTMS will improve the cognitive deficits observed during cigarette smoking abstinence and help reduce cravings for cigarettes. Ultimately, rTMS may help smokers with schizophrenia who can't quit smoking with available treatments. This study will examine the effect of rTMS on tobacco cravings and cognitive problems produced by overnight abstinence from cigarette smoking in persons with schizophrenia in comparison to people without mental illness who smoke. Important information about the potential of rTMS for the treatment of cognitive deficits and tobacco addiction in schizophrenia will be obtained. Providing more effective smoking cessation treatments in people with schizophrenia may lead to improved physical and mental health for these patients, who are extremely susceptible to tobacco addiction and tobacco-related illness.
This randomised, open-label phase III trial will be performed in patients with advanced squamous cell carcinoma of the lung requiring second-line treatment after receiving first-line platinum-based chemotherapy. The primary objective of this trial is to compare the efficacy of BIBW 2992 to erlotinib as second-line treatment in this group of patients.
The purpose of this study is to compare accuracy of a new three-dimensional ultrasound (3D US) technique with the traditional palpation method for identification of the needle insertion site on patients' skin before epidural needle placement in pregnant women. The investigators hypothesize that the needle puncture site identified by 3D US is located within a 5 mm radius from the puncture site identified by palpation.
Primary Objective: - To evaluate the efficacy of once daily dose of SAR302503 in subjects previously treated with ruxolitinib and with a current diagnosis of intermediate-1 with symptoms, Intermediate-2 or high-risk primary myelofibrosis (PMF), post-polycythemia vera myelofibrosis (Post-PV MF), or post-essential thrombocythemia myelofibrosis (Post-ET MF) based on the reduction of spleen volume at the end of 6 treatment cycles; Secondary Objectives: - To evaluate the effect of SAR302503 on Myelofibrosis (MF) associated symptoms as measured by the modified Myelofibrosis Symptom Assessment Form (MFSAF) diary - To evaluate the durability of splenic response - To evaluate the splenic response to SAR302503 by palpation at the end of Cycle 6 - To evaluate the splenic response to SAR302503 at the end of Cycle 3 - To evaluate the effect of SAR302503 on the Janus kinase 2 (JAK2) V617F allele burden - To evaluate the safety and tolerability of SAR302503 in this population - To evaluate plasma concentrations of SAR302503 for population PK analysis, if warranted
Recently, direct evidences point to the contributing role of peripheral muscle fatigue in exercise tolerance among patients with COPD. However, the physiological mechanisms by which peripheral muscle fatigue impairs exercise tolerance are still unknown, as factors regulating peripheral muscle fatigue in COPD may be complex. One possible link between limb muscle fatigue and exercise intolerance could be enhanced afferent signals from the active limb muscles to the central command, thereby limiting central motor output and eventually leading to exercise termination. A direct method to investigate the regulation of peripheral muscle fatigue during exercise in patients with COPD is the blockade of peripheral neural afferents via lumbar anesthesia. Consequently, investigating the interplay between the peripheral muscular component and the central motor command during self-paced exercise could shed light on the regulation of peripheral muscle fatigue in COPD and its implication in exercise intolerance.
Primary total hip arthroplasty (THA) has been a very successful surgical intervention in the geriatric population. Numerous studies have reported good mid and long term results of THA in patients over the age of 60 years. With the reported high success rate of this surgical intervention, the THA surgery is being performed in younger patients who have significant joint disease. A clinical trial, using a randomized blinded design, was undertaken to compare the functional outcome of 1) alumina heads/alumina liners, and 2) alumina head/Crossfire polyethylene liners in patients 60 years of age or younger with non-inflammatory arthritis of the hip. Subjects were assessed preoperatively and at one and five years postoperatively. Ten-year follow-up is currently underway. The primary outcome measure is the WOMAC Osteoarthritis Index. Secondary measures were the RAND-12, as well as measurement of complication and revision rates. The patient's demand on the implant as calculated by the patient's age, weight, health status and activity level was also measured.
This study is intended to evaluate the efficacy and safety of Certolizumab Pegol (CZP) in combination with Methotrexate (MTX) for sustaining clinical response achieved in study RA0055 Period 1 [NCT01519791]. Subjects entering this study RA0055 Period 2 achieved sustained Low Disease Activity at Week 52 in study RA0055 Period 1.
The purpose of this study is: - To evaluate the safety of up to 3 additional courses of oral QLT091001 administered once daily for 7 days in subjects treated previously with a single 7-day course of QLT091001 in Study RET IRD 01 - To evaluate whether up to 3 additional courses of oral QLT091001 administered once daily for 7 days can maintain or improve visual function.
The purpose of this observational registry is to evaluate the long-term effectiveness, safety and performance of market-released Medtronic Neuromodulation products for Deep Brain Stimulation (DBS) for the treatment of refractory epilepsy. In addition, healthcare resource use and patient reported outcomes, such as health related quality of life will be assessed.
