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.
Background: - Prader-Willi syndrome (PWS) and MC4R genetic mutations are two conditions that can cause problems with appetite regulation. People with PWS often have behavior and thinking problems. People with MC4R mutations may have problems with attention. These problems may be related to Brain-Derived Neurotrophic Factor (BDNF), a protein that is important for brain development. Researchers want to study people with PWS and MC4R mutations to see how BDNF is involved in these conditions. Specifically, body weight and brain function will be studied, and compared with healthy volunteers. Objectives: - To study how BDNF affects body weight and brain function in people with PWS and MC4R mutations. Eligibility: - Individuals of any age who have Prader-Willi syndrome or MC4R genetic mutations. - Healthy volunteers of any age to act as control participants. Design: - Participants will be screened with a medical history and physical exam. Height, weight, and waist/hip circumferences will be measured. Blood samples will be taken for genetic and other tests. - Participants will fill out questionnaires about eating habits, pain perception, and sleep behavior. - Participants will keep a 3-day food diary to record all food and drinks eaten. - Tests and questionnaires will be given to study thinking, speech, movement, behavior, and mood. Some tests will be done on a computer; other tests will be on paper. Tests may also involve performing tasks with blocks and other objects. - Participants may have other tests as directed. These will include hot and cold sensitivity tests, imaging studies like x-rays, and measurements of body fat and water content. - Treatment will not be provided as part of this study.
The purpose of this study is to evaluate the safety and efficacy of a quadruple regimen (VX-222, telaprevir, pegylated interferon, and ribavirin)in subjects with hepatitis C with cirrhosis.
To evaluate the efficacy, safety, and tolerability of 52 weeks of subcutaneous (SC) evolocumab (AMG 145) compared with placebo when added to assigned background lipid-lowering therapy.
This multicenter, randomized, double-blind, placebo-controlled, parallel-group study will evaluate the potential of dalcetrapib to reduce cardiovascular morbidity and mortality in patients with stable coronary heart disease (CHD), with CHD risk equivalents or at elevated risk for cardiovascular disease. Eligible patients will be randomized to receive either dalcetrapib 600 mg orally daily or placebo orally daily, on a background of contemporary, guidelines-based medical care. Anticipated time on study treatment is 4 years.
To evaluate the efficacy of 0.5, 1.0, 2.0 and 4.0 g/ day of CaPre™ in reducing fasting plasma serum triglycerides over a four week period in patients with mild-to-high hypertriglyceridemia as compared to the standard of care alone.
The purpose of this study is to demonstrate that a paliperidone palmitate 3 month formulation (PP3M) is as effective as the paliperidone palmitate 1 month formulation (PP1M) in the treatment of patients with schizophrenia who have been stabilized on PP1M.
Despite the availability of several classes of very effective drugs available to treat heterozygous Familial Hypercholesterolemia (HeFH), there remains a large unmet medical need for new, effective and well tolerated therapies. There are a number of therapies given on a chronic basis to reduce long term risk, such as statins, fibrates, niacin, omega 3 fatty acids, resins, cholesterol absorption inhibitors and antiplatelet or anticoagulant drugs, but subjects with heterozygous Familial Hypercholesterolemia remain at high risk for cardiovascular events. There is still a need for acute therapies that can lead to rapid pacification of unstable plaque in order to reduce the risk of these events. This study will assess the effects of CER-001 , a recombinant human Apo-A-1 based HDL mimetic, on indices of atherosclerotic plaque progression and regression as assessed by 3Tesla MRI (3TMRI)and intravascular ultrasound (IVUS) evaluations in patients with HeFH.
Major Depressive Disorder (MDD) is one of the most prevalent mental illnesses in North America, in which 30% - 40% fail to respond to conventional treatment. Repetitive Transcranial Magnetic Stimulation (rTMS) has been shown to be an effective therapeutic tool for the treatment of MDD. This form of treatment involves a series of magnetic pulses directed to the brain for about 30 minutes. Importantly, such treatment is very safe and well tolerated. However, to date, most treatment studies show modest efficacy due to limitations, including: 1) treatments that are delivered to only one side of the brain; 2) treatment that does not directly target a specific brain region associated with depression; 3) treatments that are of short duration; 4) treatments that are of insufficient intensity; and 5) insufficient understanding of the brain mechanisms responsible for therapeutic effect. This study is designed to directly address all of these limitations, as well as explore brain mechanisms (e.g. cortical excitability) through which treatment is optimized.
The purpose of this study is to determine whether giving Ipilimumab at a dose of 10mg/kg will extend the lives of subjects with unresectable or metastatic melanoma more than giving Ipilimumab at a dose of 3 mg/kg
This study (ARD-3150-1201, ORBIT-3) will evaluate the safety and efficacy of inhaled Pulmaquin (ciprofloxacin dispersion for inhalation) compared to inhaled placebo in subjects who have a confirmed diagnosis of non-cystic fibrosis (non-CF) bronchiectasis with a history of pulmonary exacerbations and chronic P. aeruginosa infections.
