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 the study is to test the hypothesis that ultrasound imaging and spectroscopy may be used as a predictive marker of advanced tumour response to neoadjuvant treatment consisting of chemotherapy or concurrent chemotherapy-radiotherapy. The main goal is to select the best ultrasound spectroscopy parameter and vascular-distribution index to use as an early predictor of pathological complete or partial response as a primary endpoint and tumour size decrease as a secondary endpoint.
Oral cavity cancer (OCC) is one of the most common cancers worldwide, with tongue cancer being one of the most common subtypes. Patients with oral cancers can experience painful swallowing, swallowing difficulty (dysphagia), and associated weight loss long after surgery. Not only is dysphagia an independent predictor of quality of life (QoL) in cancer survivorship, it can also have a devastating impact on the health of patients resulting from complications such as pneumonia, malnutrition and feeding tube dependence. Emerging evidence suggests that patients undergoing surgery benefit from engaging with speech-language pathologists (SLPs) before problems arise, to learn swallow strategies that may become useful in their rehabilitation. This in turn has the potential to reduce complications and minimize the length of feeding tube dependency. This study will assess the feasibility of conducting a prospective clinical trial that would evaluate the effects on patient health, function and overall benefit of early and systematic SLP speech and swallowing intervention for head and neck cancer patients planned for curative surgical treatment. We will also assess long-term changes in select clinical and patient-reported outcomes comparing their status before, and one month after, treatment.
This study aims to evaluate the outcomes of a rural-DOC Pilot clinic which will be established in the Huntsville site of Muskoka Algonquin Healthcare. Patients from the Muskoka region who are confirmed to have a low-risk penicillin allergy are eligible for participation in the DOC clinic. Following their experience with the DOC, participation in this study will be voluntary and feedback will be requested from each participant, and local primary care providers. The feedback will be used to assess the impact of the DOC clinic on participants and the medical community over the 2 - year study. Feedback will also be collected to investigate ongoing antimicrobial use for those participants who were successfully delabeled. This will be accomplished by surveying participants at six and twelve months after their DOC.
This project will use a mixed design and will be conducted at the West Parry Sound Health Centre. Based on similar studies there is an expected 10% drop-out rate so 20 participants per group will be invited to aim to have 15 finish. Total participants invited over the two-year study will be 40. The participants will be followed over a Complete 6-month Lifestyle medicine Intervention Program (CLIP) involving a collaboration between physicians, health coach, registered dietitians, and kinesiology. The CLIP will cover the 6 pillars of lifestyle medicine in 12-14 fundamentals of lifestyle medicine group classes.
This is a parallel, Phase 3, 2-arm study to evaluate the efficacy and long-term safety of dupilumab treatment in children 2 to <6 years of age with uncontrolled asthma and/or recurrent severe asthmatic wheeze. The study will be conducted in 2 parts. Part A will be a 52-week, randomized, double-blind, placebo-controlled study to assess the safety and efficacy of dupilumab in children aged 2 to <6 years old with uncontrolled asthma and/or recurrent severe asthmatic wheeze. At the end of Part A, all eligible participants will be offered participation in Part B, an optional open-label extension phase. Study details include: Part A: The study duration of part A will be up to 68 weeks consisting of a 4-week Screening, a 52week treatment period, and a 12-week post-treatment follow-up period. For participants who will chose to participate in Part B, the study duration will be up to 120 weeks (additional 52-week treatment period). Part B: For participants who will choose to participate in Part B, the study duration will be up to 120 weeks (Part A [4-week Screening and a 52-week treatment period] plus additional 52-week treatment period and a 12-week post-treatment follow-up period).
This study will compare the cosmetic scar result from the use of scalpel, electrocautery, and pulsed electron avalanche knife (PEAK) PlasmaBlade (PPB) for the initial skin incision for total mastectomy procedures without immediate breast reconstruction. It is hypothesized that there will be no significant difference in mastectomy scar cosmesis. The purpose and objectives of this study are: 1. To evaluate and compare the cosmetic scar result from the use of scalpel, standard electrocautery, or PEAK PlasmaBlade for initial incision for total mastectomy procedures without immediate breast reconstruction. 2. To inform future equipment choices for breast surgery including potential elimination of scalpels and their attendant risks.
The goal of this observational study is to define the course of the retinal degeneration in a ZSD patient cohort. The objective of this study is to gather information so the investigators can: 1. define the course of the retinal degeneration in a ZSD patient cohort with retinal degeneration 2. define what tests best monitor the progression of the retinal degeneration 3. generate prognostic information about vision loss in ZSD. At each yearly visit, the participants will answer a functional vision questionnaire, have a physical evaluation, blood test, and participate in a variety of vision tests. The investigators will also collect pertinent medical history. Participants will travel to study site. The study will provide financial support for board and travel.
This is a multi-centre, single cohort trial of patients undergoing cruciate-retaining total knee arthroplasty with the Attune Cementless, Fixed Bearing, Cruciate Retaining TKA System.
The goal of this clinical trial is to learn about how well tezepelumab (pronounced TEZ e PEL ue mab), a Health Canada-approved drug for severe asthma, works in participants with coexisting allergic asthma and allergic rhinitis (hayfever). The main questions it aims to answer are: - How well does the study drug work to reduce nasal symptoms following exposure to an allergen after 6 doses, and after 12 doses? - Does the study drug reduce chemicals found in the nose known to be involved in the allergic rhinitis response? Both allergic and non-allergic participants will be enrolled in the study. Non-allergic participants will: - Not be receiving the study drug. - Be exposed to allergen via the Nasal Allergen Challenge, which involves the administration of allergen extract directly to the nose. - Complete nasal symptom and quality of life questionnaires - Have nasal fluid and blood samples collected at various time points up to 24 hours following allergen exposure. - Visit the clinic 3 separate times: - At a screening visit to determine their eligibility to participate in the study - At the baseline Nasal Allergen Challenge visit - At the 24-hour post-Nasal Allergen Challenge follow-up visit Allergic participants will: - Receive one dose of tezepelumab every 1 month for 12 months. Tezepelumab will be administered as an injection into the fatty layer just beneath the skin on the stomach, arm, or thigh. - Be exposed to allergen via the Nasal Allergen Challenge, which involves the administration of allergen extract directly to the nose. - Complete nasal symptom and quality of life questionnaires - Have nasal fluid and blood samples collected at various time points up to 24 hours following allergen exposure. - Visit the clinic 17 separate times: - At a screening visit to determine their eligibility to participate in the study - At the baseline, 6-month, and 12-month Nasal Allergen Challenge visits - At each 24-hour post-Nasal Allergen Challenge follow-up visit - For each dose of the study drug The investigator will compare changes in nasal symptoms and allergic chemicals measured from nasal fluid and blood samples between non-allergic participants and allergic participants at baseline and at 6- and 12-months following the use of the study drug.
In Canada, depression affects more than 300,000 adults over the age of 60, which costs the healthcare system an estimated $5 billion each year. Late-life depression (LLD) is associated with more deaths, more physical and mental health problems. LLD is hard to treat, as many people will not respond to treatment and many will stop taking antidepressant medication due to negative side-effects. Unfortunately, common non-medication treatments like cognitive behavioral therapy are often inaccessible because of long (6-12 months) wait times and high costs. In a previous study, we found that an 8-week group mindfulness-based cognitive therapy (MBCT) program improved depressive symptoms more than regular LLD treatment (i.e. antidepressants and/or support counseling). Now, a larger scale study is required to compare MBCT to an active control group. Furthermore, research and clinical experience during and post-Covid pandemic has shown that older adults are nowadays far less likely to participate in in-person intervention studies but appreciate and tolerate Zoom delivery of behavioral interventions. This study will compare the effects of MBCT versus an active control group, Health Enhancement Program (HEP), both delivered by Zoom, to see if it improves symptoms of depression in older adults. The study team plans to recruit approximately 100-120 participants in across Canada, who will be randomly assigned to 8-weeks of either MBCT or HEP, delivered by Zoom. The investigators will observe if these treatments improve depression as well as cognition by conducting in-person cognitive assessments. Currently there is a lack of affordable and accessible non-medication treatments for LLD that can be scaled to reach many people. If successful, Mindfulness may be a potential solution, as it is easily given in groups and is well-tolerated by older adults with LLD.
