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.
Ventilation heterogeneity is a hallmark feature of most obstructive pulmonary diseases. In particular, chronic obstructive pulmonary disease (COPD) is pathologically and physiologically characterized by small airway destruction and marked airway cellular inflammation, which result in prominent expiratory airflow limitation, air trapping, hyperinflation and abnormal gas exchange. COPD is strongly linked with the exposition to inhaled irritants, most notably tobacco smoke, and is as such a potentially preventable disease. COPD-related morbidity, mortality and social costs are high: in Canada, COPD is the main cause of hospital admission among all chronic diseases and is the fourth leading cause of death. Diagnosis of COPD requires the objective demonstration of expiratory airflow limitation using spirometry. In the right clinical context, a post-bronchodilator forced vital capacity (FVC) / forced expiratory volume in 1 second (FEV1) ratio <0.70 is considered indicative of the presence of COPD, and therefore pulmonary function testing is required to make the diagnosis. However, the natural history of COPD represents a slowly-progressive continuum: active smokers that do not meet the criteria for COPD are still at risk of developing the disease. In fact, when compared to healthy non-smokers, active smokers without overt COPD can already show some pathological and clinical features of the disease. Notably, they report increased levels of resting dyspnea, chronic cough, lower exercise capacity, exercise-induced dynamic hyperinflation and marked airway inflammatory cellular infiltration, while conserving normal pulmonary function test values. These findings highlight the negative, clinically-measurable effects of tobacco smoking on pulmonary function, but also the limitations of standard pulmonary function testing in identifying the presence of early, mild airway disease and quantifying physiological limitations in these subjects. As such, there is a need for a novel, simple and reliable method of quantifying airway disease in this population. Quantitative lung ventilation single-photon emission computed tomography (SPECT) allows an objective quantification of the regional heterogeneity of ventilation in humans. The coefficient of variation (CV) of the distribution of a radioactive tracer, inhaled during the test, allows the generation of heterogeneity maps and density curves of small elements of the lung. These variables are sensitive to the presence of COPD, asthma, air trapping and are correlated to even slight anomalies in pulmonary function testing in otherwise healthy subjects. As such, SPECT could prove useful as an early marker of airway disease in active smokers at risk of developing COPD, but its use in this context has never been formally tested. This pilot study addresses the question of whether lung SPECT could provide clinically relevant information on airway disease in active smokers without overt lung disease on pulmonary lung function testing.
To evaluate the safety and tolerability, as well as the pharmacokinetic and pharmacodynamic profiles of single and multiple doses of Eplontersen administered subcutaneously to healthy volunteers and patients with Hereditary Transthyretin-Mediated Amyloidosis (hATTR ).
Randomized double-blind/placebo study to evaluate the efficacy of ASN002 in subjects with severe chronic hand eczema.
This is a single-arm, open-label, Phase 4 study evaluating the effect of GO on the QTc, pharmacokinetics, safety, and immunogenicity of GO as a single-agent monotherapy in adult and pediatric patients with relapsed or refractory CD33-positive AML.
This study is looking at the safety and effectiveness of stool transplant, also known as Fecal Microbiota Transplantation (FMT) and prebiotic supplementation in the management of metabolic syndrome. Metabolic syndrome is a common progressive medical condition that is linked to obesity, diabetes, and heart disease. Obesity and metabolic syndrome are associated with abnormalities in gut flora which lead to chronic inflammation. This chronic inflammation is thought to worsen the insulin resistance and heart disease seen with metabolic syndrome. Current treatment strategies have shown limited effect, are expensive, and have side effects with long-term use. FMT is a one-time treatment that has been shown to replace the abnormal gut flora and improve metabolic disease by increasing anti-inflammatory short chain fatty acid (SCFA) production. However, the effects from FMT are not permanent. Prebiotic supplementation is one strategy that may help to extend the benefits of FMT by helping sustain high SCFA levels. At this point, it is not known how FMT and prebiotics work together to affect SCFA levels in participants with metabolic syndrome. This study will look at this interaction and answer if prebiotic therapy is effective in prolonging the benefits of FMT in participants with metabolic syndrome.
This study (also known as IMpassion050) will evaluate the efficacy and safety of atezolizumab compared with placebo when given in combination with neoadjuvant dose-dense anthracycline (doxorubicin) + cyclophosphamide followed by paclitaxel + trastuzumab + pertuzumab (ddAC-PacHP) in patients with early HER2-positive breast cancer (T2-4, N1-3, M0).
This is a double-blind, multi-centre, randomised, 5-arm, vehicle-controlled, parallel-group trial. The trial is designed to establish a dose-response signal and investigate the efficacy and safety of delgocitinib cream in the treatment of adult subjects with mild to severe atopic dermatitis (AD).
Iron deficiency anemia is a global health problem and the most common cause of anemia worldwide. Patients with iron deficiency (ID) and IDA can present with a multitude of symptoms including fatigue, restless legs syndrome and pica.Oral iron supplementation is associated with increasing hemoglobin in multiple studies in women, pregnant women and elderly patients.However, the optimal dose and frequency of oral iron supplementation for treatment remains unclear. The current proposed study attempts to address this gap in the literature.
The purpose of this study is to evaluate associations between neuronal damage biomarkers (S100 calcium-binding protein beta [S-100β], neuron-specific enolase [NSE], ubiquitin carboxy-terminal hydrolase L1 [UCHL1], and brain-derived neurotropic factor [BDNF]) and delirium severity and subsyndromal delirium in a homogeneous population of mechanically ventilated patients with sepsis.
The purpose of this study is to evaluate the cardiac resynchronization therapy (CRT) response in a real-world patient population and evaluate options to address non-response and patient management.
