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 study evaluates the safety and efficacy of long-term on-demand treatment with orally administered deucrictibant for acute hereditary angioedema (HAE) attacks, including laryngeal attacks, in patients with HAE due to C1-esterase inhibitor (C1-INH) deficiency (type I/II). The study will enroll patients from Study PHA022121-C201 (NCT04618211) who elect to participate in this extension study and meet the eligibility requirements.
Osteoarthritis (OA) is the most common form of arthritis, affecting millions of people worldwide and it is common in an aging population. Surgical shoulder replacement (arthroplasty) is typically considered when non-surgical measures, such as physiotherapy or medication, have failed. There are two commonly performed surgical replacement procedures in patients who have advanced shoulder OA, and are 65 years of age and older: "Total Shoulder replacement or Arthroplasty (TSA)" and "Reverse Total Shoulder Arthroplasty (RTSA)". Few studies have compared the two procedures. Surgeons face uncertainty regarding which procedure to perform in patients 65 years of age and older. This pilot Randomized Controlled Trial (RCT) will compare the "TSA" and "RTSA" procedures, in patients 65 years of age and older. Participants will be assigned at random, (like flipping a coin), to one of the two groups (TSA or RTSA). The overall goal of this pilot study is to determine which procedure produces better functional and quality of life outcomes with fewer complications within the first 12-months after surgery. Moreover, pilot data will help determining the feasibility of conducting a larger trial comparing TSA versus RTSA surgical management in 65 years of age and older participants with advanced shoulder OA.
Cubital tunnel syndrome is the second most common compression neuropathy. In severe cases, functional recovery, even with surgery, is often poor. Therefore, alternative adjunct treatments capable of increasing the speed of nerve regeneration are much needed.
Background & Rationale: Fibromyalgia is characterized by widespread pain, fatigue, mood and anxiety as well as cognitive complaints. For an unacceptable proportion of patients, depressive symptoms remain impairing despite multiple treatments. For such patients, novel treatments include non-invasive brain stimulation. Transcranial Magnetic Stimulation (TMS) targeting the dorsolateral prefrontal cortex (DLPFC) or the primary motor cortex (M1) is the non-invasive neurostimulation method with the largest evidence base in fibromyalgia. It involves generating magnetic fields outside of the body to change the firing of neurons in the brain, and has a very favorable tolerability profile. Recent meta-analyses indicate that both the DLPFC and M1 targets are associated with improvements in pain, mood and anxiety, however the benefits are more persistent when the DLPFC is targeted (Su et al, 2021 - J Clin Med). The DLPFC is important in fibromyalgia through its implication in several symptoms domains in fibromyalgia, as well as pain catastrophization. The researchers neurophysiological data and clinical data in depression suggests that the researchers can enhance the effects of TMS by using an adjunctive medication called D-Cycloserine (DCS, 100mg) in conjunction with a protocol called intermittent theta-burst stimulation (iTBS). Specifically, this data indicated that several converging features of fibromyalgia improve with augmented iTBS, specifically depressive symptoms, anxiety symptoms, fatigue, and cognitive function. The researchers therefore hypothesize that the combination of D-cycloserine and TMS will lead to greater improvements in fibromyalgia symptoms than TMS alone. Although iTBS has not yet been studied in fibromyalgia, it has a well characterized neurophysiological effect and been shown to be non-inferior to conventional TMS protocols in conditions such as depression. More importantly, its physiological basis can be manipulated with D-Cycloserine whereas this has not been convincingly demonstrated with rTMS (see Brown et al, 2019, 2021 Brain Stim). Research Question and Objectives: To conduct a randomized placebo-controlled trial of DCS in adjunct with rTMS in Fibromyalgia. Participants will be randomized to receive 100mg of DCS or placebo together with TMS.
Background : The benefits of good glycemic control are clearly established. However, achieving glycemic targets comes at the expense of the risk of hypoglycemia. Repeated episodes of severe hypoglycemia can affect long-term cognitive function, especially in developing brains. Fear of hypoglycemia, both in children and their parents, has an impact on participation in physical activity, quality of life and optimal diabetes control. During an episode of severe hypoglycemia, i.e., when accompanied by severe cognitive dysfunction requiring assistance from others, it is impossible to administer oral glucose. Glucagon administration is particularly useful in this situation, as it rapidly raises blood glucose levels and restores consciousness. Injectable glucagon was the only form approved in Canada prior to 2019. A new formulation of glucagon for intranasal administration has recently been approved by Health Canada. The arrival of this formulation seems promising because of its ease of use while ensuring similar efficacy to injectable glucagon. Furthermore, the ease of learning how to use each of the devices through a simple multimedia tool is unknown. Indeed, current studies have not focused on a virtual teaching method. The latter is of particular interest in the context of a pandemic and in order to make information more accessible to a broader population that may not be present at family glucagon education (e.g., school-based caregivers). Objective : Compare the performance (time to prepare and administer, success rate) of the intranasal versus injectable glucagon administration procedure after a short video training 3 months earlier among parents/primary caregivers and school workers who may administer glucagon to children with type 1 diabetes. Secondary objectives : 1. To assess stakeholder administration procedure preferences for the two glucagon formulations in the two groups ; 2. To explore the barriers and emotional impact (fears, perceptions, stress, etc.) related to the use of intranasal and injectable glucagon in both groups; 3. Explore the participants' preferences in relation to the teaching method of administering the two forms of glucagon.
Amblyopia is a developmental anomaly resulting from abnormal visual experiences in early life. Amblyopia causes reduced visual acuity in the absence of a pathology. Adult sensory systems are believed to be structurally invariant beyond early, critical periods of development. However, recent evidence suggest that visual functions in adults with amblyopia can be improved with optical correction alone. This study aims to investigate whether improvements in best corrected visual acuity and other visual functions can result following appropriate optical correction in adults with amblyopia. Functional measures relating to vision, binocular vision, and eye movements will be used to assess the efficacy of refractive correction for improving vision. This study will help us better understand the improvements in visual functions following optical correction, as well as the mechanisms underlying neuroplasticity in adults with amblyopia.
Atopic dermatitis (AD) is a skin condition that may cause a rash and itching due to inflammation of the skin. Therapies spread over the skin may not be enough to control the AD in trial participants who require systemic anti-inflammatory treatment. This study will assess the real-world effectiveness of upadacitinib on adult participants with moderate-to-severe AD who are inadequate responders to dupilumab or who are discontinuing from dupilumab due to safety/tolerability reasons. This study also aims to understand upadacitinib utilization patterns in real-world clinical practice. In Canada, upadacitinib is indicated for the treatment of adults and adolescents 12 years of age and older with refractory moderate to severe atopic dermatitis (AD) who are not adequately controlled with a systemic treatment (e.g., steroid or biologic) or when use of those therapies is inadvisable. CAN UpTIMISE will enroll approximately 100 adult participants, 18 years of age and above, with moderate-to-severe AD who are inadequate responders to dupilumab or are discontinuing from dupilumab from up to 25 sites in Canada. Participants will receive oral upadacitinib tablets as prescribed by the physician prior to enrolling in this study in accordance with the terms of the local marketing authorization and professional and reimbursement guidelines with regards to dose, population, and indication. The overall duration of the study is approximately 4 Months. Participants will attend regular visits per routine clinical practice. The effect of the treatment will be checked by medical assessments, using questionnaires, and reporting potential side-effects.
The primary objective of this study is to investigate the uptake/gastrointestinal absorption of fatty acids in healthy adult volunteers by using enteric coated and non-enteric coated soft capsules containing omega 3 fatty acids. Pharmacokinetic parameters such as AUC and Cmax, as well as any adverse events are recorded. As secondary objective, the short-term effects of Omega-3 supplementation on blood lipid parameters in healthy volunteers are evaluated using a Cholestech LDX analyzer to measure cholesterol and related lipids.
This study will look at how well the new medicine CagriSema helps people living with excess body weight and type 2 diabetes losing weight. Participants will either get CagriSema or a dummy medicine. Which treatment they get is decided by chance. The study will last for about 1½ years. Women cannot take part if pregnant, breast-feeding or planning to get pregnant during the study period.
The study will evaluate the safety, tolerability, and pharmacokinetics (PK) of MK-1088 in monotherapy and in combination with pembrolizumab in participants with advanced solid tumors who have not responded to conventional therapy. The effect of MK-1088 on tumor size will also be examined.
