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.
Synthetic MR Technologies has created a quantified imaging solution - SyMRI - to enable radiologists to acquire quantified images and always obtain the best contrast images. This study represents an attempt to assess the clinical utility of this software.
In the BN40031 OLE study, a dose of crenezumab of 60 mg/kg intravenous (IV) every 4 weeks (Q4W) will be offered to all participants who complete Study BN29552 or BN29553 and who meet eligibility criteria in order to evaluate safety in participants on long-term crenezumab treatment and to investigate the effect of crenezumab on the underlying disease process and disease course as an exploratory efficacy objective.
Women who take opioid substitution therapy have higher rates of unintended pregnancy, more pregnancies, and a higher risk of pregnancy complications than the general population. Current practice is to test for pregnancy only at patient request or if the clinician suspects pregnancy. This study will compare monthly pregnancy testing to current practice in a double blind randomized control trial. As many women of childbearing age as possible will be recruited from the Hamilton Clinic for Opioid Substitutional Therapy. Women assigned to the intervention will have monthly testing at the same time as their monthly urine drug testing at the clinic. The primary objective is to assess if there is a significant difference is early pregnancy detection and the secondary objectives are to assess differences in pregnancy disposition and gestational age at entry to prenatal or abortion care.
Prospective, single-centre study to determine the reference range (95th percentile) of human chorionic gonadotropin (hCG) levels in a healthy, non-pregnant, adult female population using the RAMP® Total β-hCG test.
A study of a new approach to determining if, following endotracheal intubation, the endotracheal tube (ETT) is in the trachea or the esophagus. The test for correct placement consists of inflating the cuff to a pressure of 50 (to be determined by the study) and tugging the ETT gently up and out of the mouth. The investigators hypothesize that if it is in the esophagus, it will slide easily all the way out; if in the trachea, the cuff will be impeded by catching on the lower surface of the cricoid ring, and that this will require a greater force to extubate with cuff inflated than that required for the esophagus.
Background: Emergency department (ED) providers are frequently challenged with how best to treat acute pain, specifically when non-opioid analgesics are insufficient or contraindicated. Studies have documented older patients presenting to the ED with painful conditions are less likely to receive pain medications than younger patients, and this inadequate pain control has been associated with increased risk of delirium and longer hospital stays. Given the concerns for drug interactions, adverse side effects, over-sedation and addiction; emergency physicians often report uncertainty regarding the ideal choice of opioid analgesic in older adults. There are no guidelines informing best practice for the management of acute pain in this population. Objective: The primary objective is to compare the efficacy of codeine, oxycodone and hydromorphone for acute fracture pain in patients discharged from the ED. Methods: This will be a blinded, randomized controlled trial of adults (age ≥ 18) discharged home from the ED with acute pain secondary to an upper extremity, lower extremity, rib, pelvic or vertebral compression fracture. Patients will be randomized to receive a 3-day supply of codeine, oxycodone or hydromorphone. Patients will also be given acetaminophen. Patients will be contacted by phone or email 3 days following their ED visit. The primary outcome will be differences in pain scores at 3 days assessed using the validated Brief Pain Inventory (Short Form). Secondary outcomes will include side effects (ie: confusion, constipation), adverse events (i.e, falls, healthcare visits) and pain interference with daily activity. Patients, physicians and all research staff will be blinded to group allocation. Importance: All analgesics (including opioids) prescribed to adults are associated with an increased risk of adverse events. This study seeks to inform ED providers of opioid efficacy, side effects and patient-important, functional outcomes in this growing patient population.
The purpose of this study is to assess the treatment effect of intravenous TAK-954 in improving the average daily protein adequacy received through enteral nutrition in critically-ill participants developing EFI.
The MRI tools developed by the investigators are well positioned for assessing regional changes in lung structure and function in preterm children with bronchopulmonary dysplasia (BPD), in which airway limitation similar to asthma, alveolar simplification similar to emphysema and pulmonary vascular stunting are expected. To the investigator's knowledge, the combination of ultra short echo time (UTE) proton, pulmonary vascular proton and hyperpolarized 129Xe MRI have not yet been explored in BPD, either clinically or preclinically. The investigators propose that a comprehensive MRI examination may be useful from a diagnostic perspective, MRI of preterm children without BPD may reveal changes which are otherwise clinically 'silent' yet still place children at risk for future chronic lung disease in later life.
Systemic amyloidoses are rare diseases affecting approximately 1 in 100,000 persons each year. In systemic amyloidoses abnormal proteins deposit in bodily organs and severely impair their function, causing death if not treated effectively. Light chain (AL) amyloidosis is caused by a usually small population of plasma cells (the cells that produce antibodies). These cells produce part of antibodies, the light chains (LC) that form amyloid deposits. Almost every organ, with the exception of the brain, can be affected by AL amyloidosis. The heart is involved in three fourths of patients and is responsible for almost all the deaths occurring in the first 6 months after diagnosis. Current therapy of AL amyloidosis is based on drugs targeting the plasma cells producing the amyloid-forming LC. At present, most patients receive a powerful anti-plasma cell drug, bortezomib, as part of their initial treatment. However, bortezomib-based therapy, can improve heart involvement only in less than one third of patients with AL amyloidosis, and many patients (approximately one third) still die within 12 months from diagnosis. Early cardiac deaths remain an acute unmet need and the major determinant of overall outcome in this disease. Thus, there is the need of alternative means to treat heart involvement in AL amyloidosis. Doxycycline is a widely used, well tolerated, antibiotic that has been marketed for decades and used to treat a number of different infectious diseases caused by bacteria. This molecule has been extensively studied in the laboratory, in animal models and, more recently, in small studies involving patients, for its potential of improving cardiac damage in amyloidosis. These studies showed that doxycycline disrupts amyloid deposits, reduces the amyloid load in a mouse model, and counteracts the toxicity exerted by amyloid-forming LCs on C. elegans, a worm whose pharynx is used as a model resembling human heart. In a small clinical study, doxycycline was given to patients with cardiac AL amyloidosis during treatment for their underlying plasma cell disease. This resulted in a remarkable improvement of survival compared to "matched historical controls" (i.e. similar patients who had received only anti-plasma cell therapy without doxycycline in the past). Based on these promising preliminary results, we designed the present clinical trial to assess whether the addition of doxycycline to anti-plasma cell therapy can improve survival in patients with cardiac AL amyloidosis who were not previously treated. The rate of survival at 12 months will be compared in patients receiving doxycycline and in controls receiving standard antibiotic therapy, together with anti-plasma cell therapy. Patients will be assessed for parameters of plasma cell disease, heart involvement and possible involvement of other organs, as well as for quality of life. To make sure that patients who will receive doxycycline and those who will not have comparable severity of cardiac disease, patients will be stratified according to the stage of cardiac involvement. Patients with very advanced heart dysfunction will not be enrolled in the trial, because preliminary data indicate that doxycycline is of little or no benefit in these subjects. Patients will be randomized to receive doxycycline or standard antibiotics in combination with anti-plasma cell therapy. Bortezomib-based treatment directed against plasma cells will be delivered according to each participating institutions' guidelines. Doxycycline will be administered at a dosage of 100 mg two times a day, which is usual in the treatment of bacterial diseases. Standard antibiotics will be delivered according to each participating institutions' guidelines (provided that drugs of the same class as doxycycline are not administered) in the control arm. Patients will be provided a diary to record possible adverse events and will be instructed accordingly. Patients will be evaluated at trial centers every 2 months for treatment efficacy and toxicity. In case of unsatisfactory response second-line therapy will be initiated. In the absence of unacceptable toxicity, doxycycline administration will be continued for the entire duration of follow-up (12 months).
The QBECO-CD-02 trial in subjects with moderate to severe Crohn's disease (CD) is intended to build on past experience with QBECO SSI and further establish the safety and efficacy of QBECO SSI for the induction of clinical and/or endoscopic response and remission. The study will be conducted in three stages; a Lead-in, Main Induction and Main Maintenance .The first 20 patients will be enrolled in the Lead-in study, at approximately 5 study centers in Canada. Subsequent patients will be enrolled in the Main study, which aims to enroll 150 patients. The Lead-in component will be an open-label study to evaluate endoscopic healing endpoints. The Main Induction study will be randomized and placebo-controlled. Participants meeting response criteria following the Main Induction study will be eligible to continue into the Main Maintenance study, remaining on their initially randomized treatment. Participants not meeting response criteria will complete their follow-up and study involvement at the end of the Main Induction.
