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.
This is a Phase 3 multicenter, double-blind, randomized, placebo-controlled study assessing the efficacy and safety of lenabasum for the treatment of dermatomyositis. Approximately 150 subjects will be enrolled in this study at about 60 sites in North America, Europe, and Asia. The planned duration of double-blind treatment with study drug is up to 52 weeks.
Sleep apnea (OSA) is a condition in which the air passage in the throat closes or partly closes during sleep and repeatedly interrupts breathing. The standard treatment for sleep apnea is continuous positive airway pressure (CPAP), but it is not suitable for all patients. Another treatment is to use an oral appliance in your mouth when you sleep. The appliance covers the upper and lower teeth and acts to pull the lower jaw forward, opening the throat passage and allowing normal breathing. Oral appliance therapy does not treat sleep apnea effectively in everyone. In order to identify the people in whom oral appliance therapy will work, Zephyr Sleep Technologies has invented a feedback-controlled device that tests various positions of the lower jaw. This commercially available device, known as MATRx plus, is a Health Canada approved and FDA cleared motorized dental positioner that can be used in an overnight sleep study performed in the home. Temporary dental impression trays cover your upper and lower teeth. These are attached to a small motor that slowly and gently pulls your lower jaw forward under the control of a computer in response to real-time breathing events. The commercial MATRx plus device uses measures of airflow from a nasal cannula and blood oxygen saturation from a pulse oximeter to guide the movement of the lower jaw during the test. Though the test is accurate, the equipment can be somewhat cumbersome to apply. The purpose of the study is to validate a simplified version of the test that requires fewer sensors and sleep time.
The aim of this study is to compare the use of FDG PET/CT to Ga-68 HA-DOTATATE (abbreviated DOTATATE) PET/CT in patients with active giant cell arteritis (GCA) started on prednisone to understand if DOTATATE can identify more areas of active blood vessel inflammation than FDG.
The purpose of this trial is to examine the effects of a novel, orally consumed dietary supplement (composed of naturally occurring components) on weight management and metabolic rate in individuals who are overweight or obese following a 12-week supplementation period. The investigator's primary outcome will be changes in body composition measured via dual energy x-ray absorptiometry (DXA), which will measure changes in fat and lean mass during the supplementation period. Another primary objective will be to determine whether or not the body mass index (BMI) changes during the supplementation period. A secondary objective of the study is to determine whether anthropometric measurements (waist-to-hip ratio) is altered following the supplementation period. Another secondary objective of this study is to determine whether metabolic rate (as measured in VO2 consumption at rest and during exercise) is changed following the supplementation period. Another secondary objective is to determine whether blood pressure (systolic and diastolic pressure, measured in mm Hg) and physical function (measured via VO2peak in mL/min/kg-1 and leg strength in kilograms) change when the supplement is administered over a 12-week period. Another secondary objective will determine how glycemic control, blood markers of inflammation and cholesterol are affected by this intervention.
The purpose of this study is to determine whether high grade epithelial ovarian cancers (=HG EOC) are 18F-DCFPyL (=2-(3-(1-carboxy-5-[(6-[18F]fluoro-pyridine-3-carbonyl)-amino]-pentyl)-ureido)-pentanedioic acid)-avid and to compare the performance of this PET to CT and findings at time of surgery Background: There is a need for better noninvasive tools that will map disease extent in HG EOC. A recent study has shown that at immunohistochemistry GCP=II is overexpressed in ovarian cancer tumors, both primary and metastatic. Glucose carboxypeptidase-II (=GCP-II), also known as prostate specific membrane antigen (= PSMA) has been used clinically to assess patients with prostate cancer and many other tumors have been shown to be PSMA-avid on PET (including renal cell carcinomas). 18F-DCFPyL has the potential to improve patient selection for primary therapy. If successful, this may decrease the rate of futile surgeries and associated morbidity and better direct patients to the most appropriate therapy primary debulking surgery (PDS) vs neoadjuvant chemotherapy (NACT). Furthermore, if high-level GCP-II expression is shown at preoperative imaging in patients with HG EOC, this may be used in considering feasibility of future theranostic applications. Study Design: This is a single arm pilot study to assess whether HG EOC are 18F-DCFPyL-avid. In this prospective trial, the investigators will recruit 20 women whom will undergo conventional staging with contrast-enhanced CT of the abdomen and pelvis as per standard of care. All disease sites, primary and metastatic will be recorded using a standardized reporting template. Subsequently, 18F-DCFPyL-PET/CT will be performed (within 6 weeks of CT). All disease sites on PET will be recorded using same reporting template in addition to qualitative and semiquantitative evaluation (SUV measurement) of all known tumor sites.
Lithium is a mainstay in the treatment of bipolar disorder, and a frequently used adjunctive therapy for major depressive disorder. It is accepted practice to monitor lithium serum levels to monitor for efficacy and toxicity. However, studies on the difference in lithium levels between once and twice daily dosing, which also assess the impact of kidney function are scarce. The aim of this study is to quantify this pharmacokinetic difference, identify the impact of kidney function, in the context of estimating effects to inform feasibility and sample size needed for a larger well-powered study.
This study examines the impact of increasing energetic stress during an 8-hour fast on metabolic pathways in human skeletal muscle. Specifically, participants will undergo two 8-hour fasting sessions in a randomized crossover fashion, with the addition of low-intensity arm exercise in one of the sessions. Changes in metabolic pathways will be examined in resting (leg) muscle before, during, and after the fast.
The execution of this study is pertinent to evaluating SBRT's short- and long-term efficacy and safety in the treatment of SRMs. This study will be the first to compare RFA and SBRT in the treatment of SRMs.
To assess safety and tolerability, describe the dose-limiting toxicities, assess the preliminary antitumor activity, determine the maximum tolerated dose (MTD) or the highest protocol-defined dose (maximum administered dose) in the absence of establishing the MTD, and a recommended dose for further evaluation of MEDI7247 in patients with selected advanced or metastatic solid tumor malignancies that have received at least 1 prior line of treatment.
This study will look at the long-term effects of semaglutide (active medicine) on diabetic eye disease when compared to placebo (dummy medicine). The study will be performed in people with type 2 diabetes. Participants will either get semaglutide or placebo in addition to their diabetes medicines - which treatment the participant gets is decided by chance. Participants will inject the study medicine using a pen-injector. The medicine must be injected in a skin fold in the stomach, thigh or upper arm once a week. The study will last for 5 years.
