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.
To evaluate the tumour response rate of squamous cell carcinoma of the head and neck following stereotactic body radiotherapy (SBRT) of 45Gy in 5 fractions delivered once every 3-4 days, such that treatment is completed within 15 days.
This trial studies whether the blood marker micro ribonucleic acid (miRNA) 371 can predict the chance of cancer returning in patients with germ cell cancers. Studying samples of blood from patients with germ cell cancers in the laboratory may help doctors predict how likely the cancer will come back.
The COVID virus is acquired through droplet and micro droplet transmission. Although healthcare workers must adhere to strict up-to-date clinical procedures to minimize exposure to the virus and avoid contamination, the assumption that everyone can precisely remember every step is improbable as many of these procedures are quite complex and involve multiple steps in stressful situations. Further the use of a trained safety officer to ensure adherence is not always feasible due to the ever growing demand of healthcare providers. Investigators propose to utilize the Amazon Alexa device and Alexa Skills application to develop a voice enabled virtual assistant to guide healthcare professionals through the exact steps of clinical procedures including the donning and doffing of PPE, intubation and extubation procedures. Methods A total of 10 staff anesthesiologists will be recruited to participate in phase 1 of the study to evaluate the utility and functionality of this VA device. A total of 40 healthcare professionals will be recruited to participate in phase 2 of the study. Anesthesia providers (staff and fellows), anesthesia assistants, respiratory assistants and operating room nurses will be randomized to receive instructional guidance by the VA on one test occasion and a human coach on another occasion. During this phase of the study, the effectiveness of this VA prototype will be compared with a trained human safety officer / coach in its ability to provide instructional guidance for 4 safety and clinical procedures: 1) proper donning of personal protective equipment (PPE); 2) doffing of PPE; 3) intubation (putting in a breathing tube) and 4) extubation (taking out a breathing tube).
This is a multinational multicenter cross-sectional study in patients with a definite diagnosis of PsA. The population of interest will consist of 400 adult patients diagnosed with PsA and fulfilling the classification criteria for PsA and not receiving biological or targeted synthetic disease modifying antirheumatic drugs (b or tsDMARDs). Participating rheumatologists are encouraged to include consecutive PsA patients not treated with biologic or a targeted synthetic disease-modifying antirheumatic drug because of their potential impact on active inflammatory changes in the axial skeleton, which will be the focus of the current study. Patients will be recruited prospectively in selected study centres and will undergo study-related examinations including imaging of the axial skeleton (X-rays and magnetic resonance imaging). Collected data will serve as a basis for the judgement on the presence or absence of axial involvement by the local investigator and, independently, by the central study committee.
The primary aim of this study is to establish how frequently patients with coronary artery disease present or develop two anxiety disorders (panic disorder and generalized anxiety disorder) in the two years following a medical intervention for their heart. A second objective is to assess the impact of these anxiety disorders on the health of these patients.
Beta-thalassemias and hemoglobinopathies are serious inherited blood diseases caused by abnormal or deficiency of beta A chains of hemoglobin, the protein in red blood cells which delivers oxygen throughout the body.The diseases are characterized by hemolytic anemia, organ damage, and early mortality without treatment. Increases in another type of (normal) hemoglobin, fetal globin (HbF), which is normally silenced in infancy, reduces anemia and morbidity. Even incremental augmentation of fetal globin is established to reduce red blood cell pathology, anemia, certain complications, and to improve survival. This trial will evaluate an oral drug discovered in a high throughput screen, which increases fetal globin protein (HbF and red blood cells expressing HbF)and messenger ribonucleic acid (mRNA) to high levels in anemic nonhuman primates and in transgenic mice. The study drug acts by suppressing 4 repressors of the fetal globin gene promoter in progenitor cells from patients. The drug has been used for 50 years in a combination product for different actions - to enhance half-life and reduce side effects of a different active drug- and is considered safe for long-term use. This trial will first evaluate 3 dose levels in small cohorts of nontransfused patients with beta thalassemia intermedia. The most active dose will then be evaluated in larger subject groups with beta thalassemia and other hemoglobinopathies, such as sickle cell disease.
A study designed to evaluate the safety of crovalimab with eculizumab in participants with PNH currently treated with complement inhibitors. This study will enroll approximately 190 participants.
The objective of this study is to demonstrate the feasibility of novel MRI-guided ultrasound stimulated microbubble treatment to enhance radiation effects in humans receiving external beam radiotherapy delivered using a LINAC (linear accelerator) radiation therapy device.
This trial collects clinical data and blood samples to predict the quality of response to specific treatments in patients with chronic graft-versus-host disease (cGVHD) who are about to start initial or second-line therapy. Collecting and analyzing clinical data and blood samples from patients with cGVHD before and after treatment initiation may help doctors identify changes that may predict treatment response.
Preterm infants often suffer from apnea of prematurity (AOP; a cessation of breathing) due to immaturity of the respiratory system. AOP can lead to oxygen shortage and a low heart rate which might harm the development of the newborn, especially the central nervous system. In order to prevent oxygen shortage, infants are treated with non-invasive respiratory support and caffeine. Despite these treatments, many preterm newborns still suffer from AOP and need invasive mechanical ventilation. Although this will result in complete resolution of AOP, invasive mechanical ventilation has the disadvantage of being a major risk of chronic lung disease and impaired neurodevelopmental outcome. Restrictive invasive ventilation is therefore advocated nowadays in preterm infants. Doxapram is a respiratory stimulant that has been administered off-label to treat AOP. Doxapram, as add-on treatment, seems to be effective in treating AOP and to prevent invasive mechanical ventilation. It is unclear if a preterm infant benefit from doxapram treatment on the longer term. This study compares doxapram to placebo and hypothesizes that doxapram will protect preterm infants from both invasive ventilation (and related lung disease) and AOP related oxygen shortage (and related impaired brain development).
