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 study is to demonstrate the pharmacodynamic (PD) effects of E2027 on cerebrospinal fluid (CSF) cyclic guanosine monophosphate (cGMP) in participants with DLB and PDD with and without amyloid copathology after 9 weeks of treatment.
This is a multiple dose, randomized, placebo-controlled, double-blind study of belcesiran to evaluate the safety, tolerability, PK, and PD in adult patients with PiZZ AATD-associated liver disease (AATLD). The study will be conducted in 3 separate cohorts. A total of up to 16 participants may be enrolled in Cohort 1 and 2. A total number of 30 subjects will be enrolled in cohort 3. The 3 cohorts are differentiated by the duration of the treatment period, the number of doses administered, and the timing of the second liver biopsy.
Posttraumatic Stress Disorder (PTSD) will be a severe problem in Canada in the wake of COVID-19, especially for Military Members, Veterans, First Responders, and Healthcare Workers (MVFH). However, gold standard face-to-face PTSD treatments do not meet current MVFH needs, which requires virtual interventions and minimal healthcare resources. Recognizing the need for a virtual, low-resource PTSD intervention for MVFH with PTSD and their loved ones, the investigators developed Couple HOPES (Helping Overcome PTSD and Enhance Satisfaction). Couple HOPES is a secure, online self-help intervention for those with PTSD and their partners (www.couplehopes.com). However, MVFH are now particularly likely to be exposed to traumas related to COVID-19. It is essential to identify if Couple HOPES is safe and helpful for couples involving MVFH with COVID-19-related PTSD specifically. This project will therefore test the efficacy of Couple HOPES compared to a delayed waitlist control in 70 couples wherein one member is a MVFH with COVID-19-related PTSD. The investigators will examine if Couple HOPES is helpful in improving PTSD symptoms and relationship satisfaction for such couples, and if it is more or less helpful to this end for these couples compared to those with other forms of trauma exposure. 70 couples including a MVFH with COVID-19-related PTSD, will be randomly assigned to receive Couple HOPES or to a waitlist. PTSD symptoms and relationship satisfaction will be measured ~weekly during the intervention and one month after it. Related problems (e.g., depression, anxiety, healthcare use) will be measured before, in the middle of, after, and one month after, the intervention.
The purpose of the study is to provide preliminary comparative data on BoNT/A-DP versus Botox Cosmetic. Subsequently the sample size is primarily based on clinical judgement and practical considerations.
Chronic pain affects at least 10% of the global population but is often poorly managed, given the variable efficacy of available pharmacological treatments and the limited accessibility of multidisciplinary interventions. The legalization of cannabis in at least 14 countries and the increasing regulatory approval of cannabis preparations and synthetic cannabinoids and analogues have led to a growing interest in the use of medical cannabis products to manage chronic pain. This use is supported by research demonstrating important interactions between cannabinoids and the human endocannabinoid system and pain modulation pathways. While medical cannabis products are increasingly available to practitioners who treat pain, there is little evidence-based guidance for prescribing or titrating these treatments to manage chronic non-cancer pain. This prospective registry aims to assemble real-world data regarding the use of Spectrum Therapeutics (ST) medical cannabis products in subjects with chronic non-cancer pain in Canada. The registry will also assess treatment outcomes, including pain and related symptoms, global impressions of improvement, and change in concomitant pain medications (opioid use in particular), to better inform the utility of ST products for chronic non-cancer pain management. Primary Objective: • To describe patterns of physician selection of Spectrum Therapeutics (ST) medical cannabis treatment regimen, expressed as average daily dose of THC and CBD (in mg), and mode of administration (ingested or inhaled), in the management of chronic non-cancer pain in countries where these products are commercially available. Secondary Objectives: - To describe subject product and dose adjustment (under medical follow-up) over time. - To assess outcomes of treatment, including pain relief and effects on sleep, daily functioning, and quality of life. - To assess global impressions of treatment effectiveness as reported by subjects and physicians. - To assess changes in daily dose of opioids, other medications over time. Safety Objective: • To assess the safety and tolerability of ST products in subjects with chronic pain.
The purpose of this study is to assess if using the Impella® CP (or Impella® 2.5) device during high-risk PCI in patients with reduced left-sided heart function will result in an improvement in symptoms, heart function and health after a heart procedure compared to the current standard of care.
The study will consist of 2 periods: Double-blind Treatment and Open-Label Extension(OLE) Period. -Double-blind Treatment Period - This will be randomized, double-blind, placebo-controlled part of the study which will be conducted in parallel groups, ie,1 group receiving the active treatment (PXT3003) and the other group receiving placebo. Primary endpoint of the study will be assessed at Month 15. -Open-label Extension (OLE) Period - All subjects completing Double-blind Treatment Period will be given an opportunity to enter the OLE Period of the study and receive the active treatment (PXT3003). The duration of the OLE Period will be based on Sponsor discretion, ie, Sponsor intends to keep the study open until the study drug PXT3003 is commercially available. During this period, the long-term safety and efficacy of PXT3003 will be assessed as an exploratory objective. Double-blind Treatment Period Objectives: Primary: To evaluate the efficacy of treatment with PXT3003 (a fixed-dose combination of [RS]-baclofen, naltrexone hydrochloride [HCl], and D-sorbitol) compared to placebo in subjects with Charcot-Marie-Tooth disease type 1A (CMT1A). Secondary: To evaluate the safety and tolerability of PXT3003 treatment in subjects with CMT1A. Exploratory: To characterize the relationship between plasma biomarkers and response to PXT3003 treatment. OLE Period Objective: Exploratory: To evaluate the long-term safety and efficacy of PXT3003.
Coagulopathy, bleeding, and transfusion are common in cardiac surgical patients. Our collaborator has developed a novel point of care device that can be used to assess thrombin generation in real-time in cardiac surgical patients. The investigators will measure thrombin generation using our novel device and compare it to standard methods, while examining the association of thrombin parameters with bleeding and other clinical outcomes.
This is a prospective observational study of 100 patients undergoing liver transplantation at a single centre. Thrombin generation and kinetics will be assessed using a novel point-of-care device, and compared to conventional measures of hemostasis as well as viscoelastic tests to pinpoint specific coagulation deficits and identify potential therapeutic targets. The clinical course of patients will be followed for major bleeding and transfusion outcomes.
The purpose of this study is to test whether a kind of brain stimulation called anodal transcranial direct current stimulation (a-tDCS) can be combined with perceptual learning to improve the ability of people with age-related macular degeneration (AMD) or juvenile macular degeneration (JMD) to read words presented to them on a computer screen better than if perceptual learning alone were used. In addition, secondary measures of visual acuity will also be examined to determine whether brain stimulation can allow patients to resolve finer details of an image. The proposed treatment is the application of a-tDCS onto the participant's head, with brain stimulation aimed at Primary Visual Cortex toward the occipital pole, while patients undergo six separate sessions of training. The investigators will test the ability of participants to read words before the start of the training sessions (pre test) and after the completion of all training sessions (post test). This is a between-subjects design, and half of the participants will receive true stimulation, and the other half will receive sham stimulation. The difference between the pre and post tests when receiving active stimulation will be compared to the difference when receiving sham stimulation, because the sham stimulation is not expected to influence reading beyond a placebo. The aim of the study is to examine the potential of concurrent brain stimulation and perceptual learning as an effective treatment for macular degeneration that may be used in conjunction with more traditional eye-based interventions. The investigators hypothesize that the brain stimulation will enable higher performance in the reading task after and secondary measures after perceptual training due to an increase in the cortical excitability of the stimulated brain cells.
