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.
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.
The purpose of this study is to evaluate the efficacy and safety (including evaluating side effects) of combination of olaparib and abiraterone versus placebo and abiraterone in patients with metastatic castration-resistant prostate cancer (mCRPC) who have received no prior cytotoxic chemotherapy or new hormonal agents (NHAs) at metastatic castration-resistant prostate cancer (mCRPC) stage.
A Global Study to Determine the Efficacy and Safety of Durvalumab in Combination with Gemcitabine+Cisplatin for Neoadjuvant Treatment and Durvalumab Alone for Adjuvant Treatment in Patients with Muscle-Invasive Bladder Cancer
This is a Phase 2, randomized, double-blind, placebo-controlled study comparing the efficacy and safety of avapritinib + best supportive care (BSC) with placebo + BSC in patients with indolent systemic mastocytosis (ISM) whose symptoms are not adequately controlled by BSC. The study will be conducted in 3 parts. All patients will receive treatment with avapritinib during Part 3 including those rolling over from the placebo group.
This study consists of two periods. The objective of Period 1 is to evaluate the efficacy of upadacitinib in combination with a 26-week corticosteroid (CS) taper regimen compared to placebo in combination with a 52-week CS taper regimen, as measured by the proportion of participants in sustained remission at Week 52, and to assess the safety and tolerability of upadacitinib in participants with giant cell arteritis (GCA). The objective of period 2 is to evaluate the safety and efficacy of continuing versus withdrawing upadacitinib in maintaining remission in participants who achieved sustained remission in Period 1.
The purpose of this study is to assess the efficacy and safety of pembrolizumab (MK-3475) versus placebo in combination with neoadjuvant (pre-surgery) chemotherapy and adjuvant (post-surgery) endocrine therapy in the treatment of adults who have high-risk early-stage estrogen receptor-positive, human epidermal growth factor receptor 2-negative (ER+/HER2-) breast cancer. The primary study hypotheses are: 1) pembrolizumab is superior to placebo, both in combination with the protocol-specified neoadjuvant anticancer therapy, as assessed by pathological Complete Response (pCR) rate defined by the local pathologist, and 2) pembrolizumab is superior to placebo (both in combination with the protocol-specified neoadjuvant and adjuvant anticancer therapies) as assessed by Event-Free Survival (EFS) as determined by the investigator. The study is considered to have met its primary objective if pembrolizumab is superior to placebo with respect to either pCR (ypT0/Tis ypN0) or EFS.
This is a study to evaluate pharmacokinetics, safety and tolerability of upadacitinib in pediatric participants with polyarticular course juvenile idiopathic arthritis. This study consists of three parts: Part 1 is multiple-cohort study that consists of two sequential multiple dose groups. Participants benefiting from the study drug with no ongoing adverse events of special interest or serious adverse events will have option to enroll in Part 2. Part 2 is open-label, long term extension study to evaluate safety and tolerability. Part 3 is an additional safety cohort to evaluate long-term safety and tolerability.
This study is a prospective cohort study, following 80 morbidly obese patients undergoing bariatric surgery, specifically Roux-en-Y gastric bypass (RYGB). The investigators are measuring intestinal microbiota (IM) and oral microbiota (OM) at the beginning before any treatment, at the time of surgery, which is after a very low calorie standard diet, and 1 and 6 months after surgery. The investigators assess whether changes in IM are related to changes in insulin resistance (IR), other features of the metabolic syndrome (MetS) and OM.
In patients with a limited oligometastatic burden (cancer has spread but is not yet considered metastatic), emerging evidence suggests that treatment of all sites of disease with ablative therapies can improve patient outcomes, including overall- and progression-free survival. The application of Stereotactic Ablative Radiotherapy (SABR) for patients with 4-10 metastatic deposits appears promising, yet it is unclear if all patients with greater than 3 oligometastatic lesions benefit from ablative therapies in terms of improved Overall Survival (OS), Progression Free Survival (PFS), or quality of life. The purpose of this study is to assess the impact of SABR, compared to standard of care treatment, on overall survival, oncologic outcomes, and quality of life in patients with a controlled primary tumor and 4-10 metastatic lesions.
The objective of the VIRTUUS Children's Study is to adapt identified and validated adult noninvasive diagnostic and prognostic biomarkers for the characterization of allograft status in pediatric recipients of kidney allografts.
