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.
Axial spondyloarthritis (axSpA) is an immune-mediated inflammatory disease primarily affecting the axial skeleton. The most frequent axSpA symptom is chronic, often inflammatory back pain (IBP) that might be difficult to distinguish from other causes of chronic back pain (CBP). Many participants report persistent pain, including back pain, which impacts disease activity and quality of life including creating burdens such as sleep disturbance, social isolation, loss of productivity, as well as anxiety and depression. This study will assess the real-world effectiveness of upadacitinib on early and sustained pain control, and the association between pain and clinical/patient-reported outcomes in axSpA participants. Upadacitinib is being developed for the treatment of axSpA. Approximately 650 adult participants with active-axSpA will be enrolled across approximately 19 countries in Europe, North America, South America, and Asia-Pacific. 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. Participants will be followed for 12 months. There may be a higher burden for participants in this study compared to usual standard of care. Participants will attend regular visits per routine clinical practice. The effect of the treatment will be checked by medical assessments, checking for side effects, and questionnaires.
This study will assess the safety and efficacy of ARQ-151 cream vs vehicle applied once a day for 4 weeks by subjects with atopic dermatitis (eczema).
This Phase 2 trial will evaluate the efficacy and safety of ABP-450 for migraine prevention in adults who suffer from six or more migraine days per month. The study will enroll 765 patients across approximately 64 sites in the United States, Canada and Australia. Study subjects will be divided evenly across a low dose group, a high dose group and a placebo group. All patients will receive two treatment cycles of ABP-450 or placebo utilizing the Company's novel injection paradigm.
The pregnancy and postpartum periods can be joyous times in life; however, they can also be filled with challenging physical, emotional, and lifestyle changes. These changes may lead to feelings of stress, anxiety, and depression amongst new and expecting mothers, which can have negative effects on fetal and infant development (Beijers et al., 2010; Goodman et al., 2016). The impacts of increased worry about health and safety due to COVID-19 as well as future-related uncertainties, paired with social (physical) distancing, may be felt especially strongly in this population. Of concern, pregnant and postpartum women have low rates of mental health service use even prior to the pandemic (Fonseca et al., 2015). E-health (Internet) and m-health (mobile application) psychological interventions are accessible, available at reduced cost, and can be accessed within users' homes, a factor that is particularly important during the pandemic (Andrews & Titov, 2010). In this study, the investigators will disseminate a free, online, self-directed Cognitive Behavioural Therapy program to women experiencing symptoms of anxiety during pregnancy and postpartum. This program has shown to be effective at improving symptoms of anxiety and depression when delivered in an in-person group format, and has high acceptability (Furer & Reynolds, 2015). The investigators will transfer this program into an online format so that pregnant and postpartum users can navigate the sessions on their own, without the support of a clinician. This program contains six modules which include topics such as coping with negative thoughts, unpacking the myth of the supermom, and managing expectations during pregnancy and postpartum. Additionally, material related to COVID-19 has been added to the program to target any pandemic-related stress participants may be experiencing. The investigators will collect information about the program's feasibility, acceptability, and effectiveness, which will inform future improvements to the program. This program is expected to reduce participants' feelings of stress, anxiety, and depression, in addition to improving maternal attachment. It is anticipated that these gains will be maintained when the investigators follow-up with participants one month after program completion. This program has the potential to provide accessible and affordable mental health services to pregnant and postpartum women struggling during the pandemic.
Interventions to disrupt memory reconsolidation have held promise for the treatment of stress- and anxiety-related disorders. In the present study, the investigators will examine whether an intervention based on these principles, called memory updating, could be adapted for reward-seeking behaviors. To test this, non-treatment seeking tobacco smokers will be exposed to smoking cues and/or stress, two stimuli known to trigger smoking. It is predicted that exposure to a stress task will enhance the cues' motivational salience and yield greater susceptibility to the memory updating procedure. As an add-on, the investigators will examine COVID-associated changes in substance use and whether participants in the memory updating groups might be more resilient to these effects. It is predicted that the changes in substance use will depend on whether the substances are used primarily in social settings.
It is estimated that 23% of Quebecers suffer from chronic low back pain, and that 12% are disabled by this condition. Despite medical advances, the origin of so-called 'nonspecific low back pain' remains enigmatic. Conventional imaging methods by computed tomography and magnetic resonance may provide information on vertebral structures. However, very often, they do not diagnose lesions that genuinely correlate with the patient's symptoms. The lack of accurate diagnosis limits the therapeutic management in these patients. Therefore, patients are increasingly turning to alternative and complementary medicine therapies (e.g., acupuncture, chiropractic , osteopathy, shiatsu) to relieve their pain. These therapies target painful areas of abnormal hardening in muscles of the lower back and aim to release the tension in these tissues to control pain. However, these painful areas and their resolution after manual therapy have yet to be demonstrated by means other than manual palpation. We will conduct a randomized controlled trial in chronic low back pain patients to examine the effects of acupuncture, chiropractic therapy and therapeutic massage on lower back muscular and connective tissues' physical properties using innovative ultrasound techniques.
This is a prospective, single-center, phase II trial that will be monitoring the safety and efficacy of using stereotactic ablative radiotherapy (SBRT) to treat patients with a medical condition affecting heart rate and rhythm (refractory arrhythmias) within the University Health Network (Princess Margaret Cancer Centre and Toronto General Hospital). The primary objective will be to prospectively monitor patient cardiac outcomes following SBRT.
According to the Canadian ADHD Practice Guidelines, psychostimulants are the preferred treatment of attention-deficit/hyperactivity disorder (ADHD), especially for those that require urgent care. Specifically, long-acting psychostimulants are considered the gold-standard pharmacological treatment for ADHD. Using extended-release formulations, long-acting psychostimulants provide an extended duration of daily symptom relief in addition to overall reductions in ADHD symptoms that are maintained over time. In accordance with these guidelines, clinicians may combine psychostimulants with other medications when it is considered necessary. For complex cases, psychostimulants alone are often inadequate for improving the effects of ADHD and are therefore prescribed in conjunction with other medications. At low doses, antipsychotics have been considered appropriate adjunctive medications. Studies show that most adult cases with ADHD that were undiagnosed or untreated in childhood result in the need for adjunctive medication in adulthood to enhance the effects of the psychostimulant. As a result, it is hypothesized that adjunct treatment with a low dose of cariprazine, an atypical antipsychotic, will enhance the effectiveness of standard ADHD treatment with a long-acting psychostimulant in a subset of the ADHD population that achieved little to no response on psychostimulants alone.
Transcatheter aortic valve implantation (TAVI) serves a growing spectrum of patients with symptomatic severe aortic stenosis (AS). Approximately 80% of surgical aortic valve replacements is performed using a bioprosthesis1. Durability of surgical bioprostheses varies based on the patient's age at the moment of implantation, type and size etc2. TAVI has become the preferred treatment for degenerated aortic bioprostheses in elderly patients3. The median time since index surgical aortic valve replacement (SAVR) and for bioprosthetic valve degeneration is typically 8 - 10 years4-6. TAVI in this setting has proven to have equally favorable results as in native aortic valves7. Balloon expandable8 and self-expanding9 transcatheter heart valves (THV) can be used in a degenerated bioprosthesis and each have specific assets and limitations. TAVI in a failed bioprosthesis can cause coronary obstruction, THV migration, paravalvular leakage and prosthesis patient mismatch. The SAPIEN-3 / Ultra and EVOLUT R/Pro are the 2 most commonly used THV platforms in contemporary clinical practice including treatment of failing surgical aortic bioprostheses. Objective: To compare TAVI with EVOLUT R/Pro vs. SAPIEN-3 / Ultra in terms of device success. Study design: International multi-center randomized study with 1:1 randomization to TAVI with SAPIEN-3 / Ultra or Evolut R/Pro. Study population: 440 patients with a failing surgical aortic bioprosthesis (aortic stenosis with or without aortic regurgitation) and selected for transfemoral TAVI by heart-team consensus. Investigational intervention: Transfemoral TAVI with SAPIEN-3 / Ultra or Evolut R/PRO Main study parameters/endpoints: 1. Primary endpoint is device success at 30 days Defined by - Absence of procedural mortality AND - Correct positioning of a single prosthetic heart valve into the proper anatomical location AND - Intended performance of the prosthetic heart valve (no severe prosthesis- patient mismatch and mean aortic valve gradient < 20 mmHg or peak velocity < 3 m/s, AND no moderate or severe prosthetic valve regurgitation). Severe prosthesis patient mismatch is defined by effective orifice area (EOAi) ≤0.65 cm2/m2 2. Safety endpoint at 1 year defined by the composite of all-cause death, disabling stroke, rehospitalization for heart failure or valve related problems.
