There are about 19310 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 Phase 3 study is intended to assess the efficacy of the Quadrivalent VLP Influenza Vaccine during the 2018-2019 influenza season in elderly adults 65 years of age and older. One dose of Quadrivalent Virus-Like Particles (VLP) Influenza Vaccine (30 μg/strain) or of Comparator (15 ug/strain) placebo will be administered to approximately 12,120 subjects.
This is a multi-center, randomized, controlled, single-blind, two-way crossover efficacy and safety study in subjects with Type 1 diabetes mellitus. The study involves two daytime clinical research center (CRC) visits with random assignment to receive G-Pen glucagon 1 mg during one period and Novo Glucagon 1 mg during the other. Each daytime visit is preceded by an overnight stay in the CRC. In the morning of the inpatient study visit, the subject is brought into a state of severe hypoglycemia through IV administration of regular insulin diluted in normal saline. After a hypoglycemic state with plasma glucose < 54 mg/dL (3 mmol/L) is verified, the subject is administered a dose of G-Pen or Novo Glucagon via subcutaneous injection. Plasma glucose levels are monitored for up to 180 minutes post-dosing, with a value of >70.0 mg/dL (3.89 mmol/L) or an increase of > 20 mg/dL (>1.11 mmol/L) within 30 minutes of glucagon administration indicating a positive response. After 3 hours, the subject is given a meal and discharged when medically stable. After a wash-out period of 7 to 28 days, subjects return to the CRC, and the procedures are repeated with each subject crossed over to the other treatment. A follow-up visit as a safety check is conducted 2-7 days following administration of the final dose of study drug.
This is a pilot study to evaluate the feasibility of conducting a larger trial to determine if the use of intraoperative topical tranexamic acid (TXA) decreases the rate of post-operative hematomas and seromas in breast cancer patients after their mastectomy. In other words, the investigators want to determine if applying TXA inside the surgical wound before it is closed helps reduce blood or serous fluid accumulation at the operative site. Dependent on the results of this study, a further larger trial may or may not take place. Post-operative seromas and hematomas are common complications of mastectomy surgery not only leading to infection, discomfort, wound dehiscence or emergency room visits; they also delay in some instances post-operative adjuvant radiotherapy. Establishing whether or not topical TXA is an effective strategy to decrease those complications can potentially impact positively the breast cancer treatment. To achieve this aim, this randomized pilot study will first determine whether a larger multicenter study if feasible. This study will replicate a formal randomized trial at a smaller scale in a single center in order to assess the recruitment and randomization process, as well as provide preliminary results for our research question.
This is a Phase III randomised, double-blind, multi-centre study to evaluate the efficacy and safety of durvalumab in combination with standard of care platinum based chemotherapy and bevacizumab followed by maintenance durvalumab and bevacizumab or durvalumab, bevacizumab and olaparib in patients with newly diagnosed advanced ovarian cancer.
The objective of this study is to establish the pharmacokinetic curve for two different doses of MaxSimil at steady-state over a 20-week period, namely two (2) or three (3) tablets per day. MaxSimil is a concentrated fish oil monoglyceride (MAG) that facilitates absorption of the omega-3 oils by the body. Each capsule contains 300 mg of monoglyceride eicosapentaenoic acid (MAG-EPA) and 130 mg of monoglyceride docosahexaenoic acid (MAG-DHA). Thirty-two (32) subjects will be enrolled and randomly assigned to one of the two parallel treatment doses. Pharmacokinetics will be assessed by measuring the omega-3 index at eight (8) different times during the study. A first sample will be taken before the start of treatment and then every four (4) weeks during treatment. Then, two last measurements of the omega-3 index will be done at four (4) and seven (7) weeks after the end of treatment. Apart from the study treatment and collection of samples for the measurement of the omega-3 index, the only other interventions will be the measurement of body weight at screening and at the end of the study, pregnancy test for women at screening, questioning for demographic information and for the follow-up of the subject's health and concomitant medication intake.
Programmed intermittent epidural bolus (PIEB) is a technique of epidural analgesia in which boluses of local anesthetic solutions are injected into the epidural space at a fixed time interval. Despite the increasingly popular use of PIEB for labor analgesia, the optimum regimen of drug delivery has yet to be determined. The outcomes of a chosen regimen will depend on the local anesthetic solution used (drug, concentration and mass) and the parameters established for the PIEB, typically associated with patient controlled epidural analgesia (PCEA). Also, the optimum regimen will depend on the anesthetic and obstetric outcomes of interest. The investigators have conducted several studies aiming at establishing the optimum PIEB regimen for the patient population at Mount Sinai Hospital. High sensory block levels obtained in some of the previous studies conducted at Mount Sinai Hospital and in other studies in the literature, in spite of not determining adverse effects, suggest an imperfect use of the technique, with an exaggerated and unnecessary spread of the epidural mixture. It is possible that by limiting the spread of the local anesthetic mixture, better analgesia can be provided with less overall consumption of local anesthetic. The investigators wanted to conduct a study using boluses of 2.5 mL of bupivacaine 0.25% with fentanyl 8 mcg/mL. This would maintain the same dose of local anesthetic used in previous studies, but in a much smaller volume. This concentration and volume of bupivacaine has not been tried before as a PIEB regimen. The hypothesis of this study is that the optimum interval time between PIEB boluses of 2.5 mL of 0.25% bupivacaine plus fentanyl 8 mcg/ml will be between 30 and 60 minutes.
Eczema is a chronic disease that requires long term and extensive treatment. However patient adherence to the treatment plans provided to them by their healthcare providers is poor. Frequent follow-up appointments have been demonstrated to improve treatment adherence, this may be due to patients feeling a sense of accountability which motivates them to adhere to their treatment. However, although frequent follow-up appointments are effective, they are not feasible. The goal of the Eczema Reminder and Accountability Program (ERAP) is to assess the effectiveness of a patient reminder system on patient adherence to treatment and the outcome of eczema. Participants will receive weekly/biweekly text messages that encourage them to adhere to their treatment plan, and asks them to assess the severity of their eczema and adherence to treatment for that week using questionnaires. Participants are then asked to send the completed questionnaires to Hamilton Allergy. Should the ERAP improve eczema outcome and treatment adherence, the goal is to use the ERAP as a virtual follow-up to reduce the need for frequent in-office follow-ups.
The aim of this study is to answer the question: can the IGAR-Breast safely and effectively perform teleoperative breast biopsies? This is a prospective, pilot trial. 5-10 participants will be selected by the radiologist and the success of biopsy analyzed. In addition the number of adverse events, device events and procedural deviations will be assessed to determine safety and efficacy.
The purpose of this study is to evaluate the effect of a drug called benralizumab in individuals with severe, poorly controlled asthma with eosinophilic airway inflammation. Eosinophils are a type of white blood cell that help fight off infections. Some people with asthma have too many eosinophils in their airways and blood, which can cause airway inflammation. Benralizumab is a new drug that is Health Canada approved and has been shown to rapidly eliminate eosinophils. It has been used in patients with severe asthma to improve lung function and reduce flair-ups, also known as exacerbations. Magnetic Resonance Imaging (MRI) is an imaging tool that can look at the structure of the lungs when a subject inhales a xenon gas mixture. In healthy individuals, the gas fills the lungs evenly, but in individuals with lung disease, some of the areas of the lungs are not filled by the gas and the image looks patchy. These patchy areas are called ventilation defects and they contribute to reduced lung function. The goal of the study is to see if treatment with benralizumab will improve these ventilation defects, overall lung function and blood and sputum eosinophil levels. Subjects will receive treatment with benralizumab a total of 3 times, 4 weeks apart. Before and after treatment, subjects will undergo a series of MRI tests, breathing tests, blood and sputum analysis and a series of questionnaires to evaluate daily quality of life. The hypothesis is that ventilation defects will significantly improve after benralizumab treatment, and that this improvement will be different based on how long the patient has had asthma.
Hemodialysis (HD) patients take more pills per day on average than any other chronically ill patient population. On average, an HD patient takes 19 medications per day, of which 70% may not be appropriate. The reason the medications may not be appropriate is that HD patients are rarely included in clinical trials for new medications and therefore the efficacy and safety data that exists for the general population may not actually apply to them. Tools to guide the re-assessment and discontinuation (deprescribing) of these specific medications that lack evidence for efficacy and safety in HD patients are needed. These tools will help reduce the amount of medications being taken and the potential negative consequences of taking so many medications (e.g. adverse drug reactions, drug interactions, non-adherence, increased risk of cognitive impairment, impaired balance and falls, and increased risk of morbidity, hospitalization, and mortality). Nine medications that are often inappropriately prescribed to HD patients have been identified by the investigators. These medications are: Alpha-1 Blockers, Anticonvulsants, Benzodiazepines & Z-Drugs, Loop Diuretics, Prokinetic Agents, Proton Pump Inhibitors, Quinine, Urate Lowering Agents, and Statins. The investigators developed and validated tools to help medical teams in outpatient HD units with identifying and stopping these medications in their patients. The next step will be to perform a study where test these tools are tested in practice at multiple HD centers across Canada. This initiative should decrease the average number of medications per patient and inappropriate medication use in the HD units where these tools are used. The overall objective of this study is to improve current clinical practice by optimizing medication use and prescribing patterns in the HD units across Canada.
