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 who present with chest pain are investigated with tests designed to confirm or exclude the presence of Coronary Artery Disease (CAD), as well as determine risk of poor outcome. It is not known which imaging test would be best when used first for investigating a patient presenting with exertional chest pain. This trial is designed to compare outcomes of the use of coronary CT, stress echocardiography and nuclear perfusion (SPECT) in a pilot study. Patients with no history of coronary disease presenting with chest pain will be randomly assigned to one of the three test modalities as the initial imaging test. The three imaging strategies will be compared regarding the subsequent use of healthcare resources over a year.
Perifollicular Doppler could reflect the quality of the follicle's vascularization and, consequently, the one of the oocyte that ensues from it. Perifollicuar Doppler is the analysis, in ultrasound, of the blood flow in vessels surrounding the follicle. The goal of this study is to evaluate if there is a link, in natural cycle In Vitro Fertilization, between the quality of the vascularization and the one of the oocyte, the embryo and the pregnancy.
This is randomized, double-blind, placebo controlled, single centre; 21 days phase II clinical trial on healthy volunteers. Following baseline visit at the day of randomization, treatment with Augmentin 875mg for 7 days will be given. Concurrently and after antibiotic treatment subjects will also receive the study treatment, either probiotic or placebo. Daily Bowel Habit Diary will be completed by the subjects. The subjects will be asked to collect fecal samples for microbiological examination. The primary objective of the study is to evaluate the maintenance of intestinal microbiota composition during antibiotic treatment with Augmentin 875mg. Secondary objectives will be to evaluate the reduction in side effects associated with antibiotic use.
Sleep disorders (SD) are common in adults with Chronic Kidney Disease (CKD) on dialysis with a reported prevalence of 60-80%. To date three studies have reported on SDs in children with CKD but these have all been based on questionnaire data alone. The findings were not confirmed with polysomnograms (PSG), the gold standard to diagnose SD, or actigraphy, a validated tool to assess the sleep/ wake cycle over a prolonged period in the home. This is highly relevant given the poor sensitivity and specificity of even validated questionnaires alone. The effect of untreated pediatric SD is pervasive. This study will provide the first objective assessment of SDs using PSGs in children with severe CKD, both on and off dialysis. Therefore, we will recognize and when possible treat SD in this severe CKD cohort potentially contributing to their immediate management (eg improved control of hypertension, improved school performance), while improving their Quality of Life (QOL) and helping ensure they achieve their full potential.
Multiple Sclerosis (MS) patients often complain of cognitive fatigue. There is currently no treatment for this symptom. Fampridine SR is a recently approved medication that improves walking ability and walking speed in MS patients. It is thought that it might have the same positive effect on cognitive fatigue. This study will compare fampridine 10mg twice a day to placebo in order to determine if there is any benefit of this medication for cognitive fatigue in MS.
Cognitive impairment, or problems with thinking and memory, is common in multiple sclerosis (MS) and can occur independently of physical disability. It is the most common reason, along with physical fatigue, for MS patients to stop working. The most frequent complaint is problems with multi-tasking or thinking quickly, which corresponds to impairment in the cognitive domain of processing speed. Currently there is treatment available to prevent relapses and physical disability but there are no medications that have been shown to treat cognitive impairment. Amphetamines have been beneficial for selective attention and processing speed in attention deficit hyperactivity disorder (ADHD) and traumatic brain injury. This is study will determine whether Adderall XR improves objective measures of processing speed and attention in MS patients impaired in this cognitive domain, by comparing two doses of Adderall XR (5 and 10mg) to placebo before and after the medication is administered. The results of this study will help provide data to design a larger study to determine if Adderall XR, and potentially other amphetamine drugs, will help treat cognitive impairment in MS patients.
The purpose of this study is to determine the contribution of spinal epimorph to patient's perioperative pain management in Total Knee Arthroplasty (TKA). This study is designed to determine whether spinal epimorph and its associated complications is a necessary addition to provide adequate analgesia given the multimodal approach to pain management. It is hypothesized that perioperative local infiltration with a cocktail of local and systemic analgesics will provide equal analgesia to patients who are given both local infiltration and spinal epimorph perioperatively.
This multicenter, randomized, double-blind, placebo-controlled study will evaluate the efficacy and safety of vemurafenib in participants with completely resected, cutaneous BRAF mutation-positive melanoma at high risk for recurrence. Participants will be enrolled in two separate cohorts: Cohort 1 will include participants with completely resected Stage IIC, IIIA (participants with one or more nodal metastasis greater than [>] 1 millimeter [mm] in diameter), or IIIB cutaneous melanoma, as defined by the American Joint Committee on Cancer (AJCC) Classification, Version 7; Cohort 2 will include participants with Stage IIIC cutaneous melanoma, as defined by this classification scheme. Within each cohort, participants will be randomized (1:1 ratio) to receive vemurafenib or matching placebo over a 52-week period.
The general objectives of this study are to verify the feasibility of a short home-based rehabilitation program for cancer patients prior to lung resection surgery, and to quantify its effects on aerobic capacity, exercise tolerance and skeletal muscle strength. Therefore, the hypotheses of this study are that: 1. Implementation of a short home-based rehabilitation program (4 weeks) based on exercise training is feasible and safe in patients with lung cancer resection candidates. 2. Compared to control patients, patients included in the home-based rehabilitation program will improve significantly their aerobic capacity, exercise tolerance and arms and legs muscle force.
The purpose of phase 2 of this this study is to estimate the treatment effect of study drug measuring progression free survival.
