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 is a Phase 3, randomized, parallel-group, comparator-controlled, observer-blind, multicenter study of immunogenicity and safety in approximately 7700 male and female adults aged 50 years and older (approximately equally split between two age groups: 50-64 years; 65 years and older), who are healthy or have stable comorbidities that increase their risk of complications from influenza infection. Three lots of aQIVc will be evaluated for consistency and pooled for the comparison with the 2 control vaccines. Subjects will be randomly assigned to receive 1 of 3 lots of aQIVc, QIV1, or QIV2 in a 1:1:1:2:2 ratio (for a 3:2:2 ratio for aQIVc, QIV1, and QIV2). The study will have a treatment period (Day 1 to Day 29) and a follow-up period (Day 30 up to Day 181); a subset of 770 subjects will be followed up up to Day 365.
This two-arm, double-blind randomized clinical trial will recruit 208 generally healthy, low-risk pregnant individuals aged 19-42 years living in Vancouver, Canada. Participants will be randomized to receive one of two forms of iron (ferrous fumarate or ferrous bisglycinate) in addition to a prenatal multivitamin (without iron) daily during their pregnancy until delivery, with optional continuation until ~4 weeks postpartum for breastmilk sample collection. Blood samples will be taken at baseline and again at ~37 weeks gestation to assess how different forms of iron impact body iron stores. Rectal swabs will also be taken at baseline and ~37 weeks gestation to detect presence of harmful bacteria in the gut and quantify their abundance. This research will inform more specific guidelines for optimal iron supplementation practices for the prevention and treatment of iron deficiency for both mother and baby.
Our research group has found that Canadians with undiagnosed asthma or chronic obstructive pulmonary disease (COPD) have increased respiratory symptoms and worse health-related quality of life. The investigators recently developed and validated an on-line questionnaire to accurately identify these symptomatic, undiagnosed individuals. The investigators will advertise in the community asking individuals to complete the on-line questionnaire at home, at their leisure, to determine if they are at risk of asthma or COPD. Those at risk will be invited to participate in our randomized, controlled clinical trial to determine if guidelines-based treatment of newly discovered undiagnosed asthma or COPD will improve their quality of life and clinical outcomes.
CALM-IT is a Randomized, double-blind, placebo-controlled cross-over clinical trial. Safety and efficacy of cannabidiol (CBD) capsules assessed for managing agitation in patients with AD and to identify novel biomarkers of agitation severity and treatment response.
The primary purpose of the study is to evaluate the efficacy of brensocatib at 10 and 40 milligrams (mg) once daily (QD) compared with placebo in improving clinical symptoms of CRSsNP.
This clinical trial is studying nonsquamous non-small cell lung cancer (NSCLC). Participants in this study must have cancer that has spread through their body or can't be removed with surgery. Participants in this study must have been treated with no more than a platinum-based chemotherapy and an anti-PD-(L)1 drug. Participants with tumors that have certain treatable genomic alterations must have had at least 1 drug for that genomic alteration, in addition to platinum-based chemotherapy. This clinical trial uses an experimental drug called sigvotatug vedotin (SGN-B6A), which is a type of antibody drug conjugate or ADC. ADCs are designed to stick to cancer cells and kill them. This clinical trial also uses a drug called docetaxel. Docetaxel is an anticancer drug that has been approved to treat non-small cell lung cancer. It is usually given to patients who previously received another anticancer treatment. In this study, one group of participants will get sigvotatug vedotin on Days 1 and 15 during each 28-day-cycle. A second group of participants will get docetaxel on Day 1 during each 21-day cycle. This study is being done to see if sigvotatug vedotin works better than docetaxel to treat participants with NSCLC. This study will also test what side effects happen when participants take these drugs. A side effect is anything a drug does to the body besides treating the disease.
Alopecia areata (AA) is a disease that happens when the immune system attacks hair follicles and causes hair loss. AA usually affects the head and face, but hair loss can happen on any part of the body. The purpose of this study is to assess how safe, effective, and tolerable upadacitinib is in adolescent and adult participants with severe AA. Upadacitinib is an approved drug being investigated for the treatment of AA. In Study 1 and Study 2 Period A, participants are placed in 1 of 3 groups, called treatment arms. Each group receives a different treatment. There is a 1 in 5 chance that participants will be assigned to placebo. In Study 1 and Study 2 Period B, participants originally randomized to upadacitinib dose group in Period A will continue their same treatment in Period B. Participants originally randomized to Placebo in Period A will either remain on placebo in Period B, or be randomized in 1 of 2 groups, based off of their Severity of Alopecia Tool (SALT) score. Participants who complete Study 1 or Study 2, can join Study 3 and may be re-randomized to receive 1 of 2 doses of upadacitinib for up to 108 weeks. Around 1500 participants with severe AA will be enrolled in the study at approximately 240 sites worldwide. Participants will receive oral tablets of either upadacitinib or placebo once daily for up to 160 weeks with the potential of being re-randomized into a different treatment group at Weeks 24 and 52. Participants will be followed up for up to 30 days after last study drug dose. There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, blood tests, checking for side effects and completing questionnaires.
The goal of the clinical trial is to test whether a mental health program that is delivered through the Internet works well for healthy children and adolescents with siblings with cystic fibrosis (CF). The main questions it aims to answer are: - Does the program improve the mental health and quality of life of healthy siblings? - Does the program improve the relationship between healthy children and adolescents and their sibling with CF? - Does the program help healthy siblings learn about CF? Participants will: - Fill out an online survey asking questions about their family and mental health before the program - Complete the online mental health program over five weeks - Fill out a weekly question asking about their mood for 10 weeks - Fill out an online survey asking questions about their family and mental health after the program Healthy children and adolescents with siblings with CF will be compared against themselves. Researchers will compare participants scores before starting the program with their scores during and after completing the program. Researchers hope to develop a program that improves mental health, quality of life, sibling relationships, and knowledge about CF.
Goal directed fluid therapy (GDFT) or "Personalized fluid therapy" may benefit high-risk surgical patients but these strategies are infrequently implemented. It has also been shown that without any goal or protocol for fluid resuscitation, large inter- and intra-provider variability exist that have been correlated with poor patient outcomes. Recently, an "Assisted Fluid Management" (AFM) system has been developed to help ease some of the work associated with GDFT protocol implementation. The AFM system may help increase GDFT protocol adherence while leaving direction and guidance in the hands of the care providers. This artificial intelligence-based system can suggest administration of fluid boluses, analyse the hemodynamic effects of the bolus, and continually re-assess the patient for further fluid requirements. To date, there are no large outcome study using this AFM system. The primary objective of this trial is thus to evaluate the impact of this AFM system to guide fluid bolus administration on a composite of major postoperative complications in high-risk patients undergoing high-risk abdominal surgery.
The investigators wish to perform a pilot study at the Manitoba Men's Health Clinic to assess if pre-vasectomy counseling with ChatGPT can safely streamline the consultation process by reducing visit times, while increasing patient satisfaction with the consultation process.
