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 objectives of this study are to evaluate the effect of seladelpar treatment compared to placebo on efficacy, safety, and tolerability in patients with primary sclerosing cholangitis (PSC).
This study aims to evaluate the pharmacokinetics (PK) of apixaban in kidney and lung transplant recipients stabilized on either cyclosporine or tacrolimus as part of their immunosuppressive therapy.
The PANACEA trial is an investigator-initiated prospective, single-center, two-arm, non-blinded pilot randomized controlled trial of high-dose IV N-Acetylcysteine therapy used as an adjunct to pharmaco-invasive reperfusion in patients presenting early after a large STEMI.
In this two-arm, double-blind randomized pilot study, the investigators will recruit 60 generally healthy, low-risk pregnant women aged 19-42 years living in Vancouver, Canada. Participants will be randomized to supplement with either 0.6 mg/day folic acid or an equimolar dose (0.625 mg/day) of (6S)-5-methyltetrahydrofolic acid for 16-weeks of their pregnancy. Randomization will occur at 8-21 weeks gestation (after neural tube closure) to reduce the risk of harm should the natural folate prove less effective. All participants will also receive a prenatal multivitamin not containing any form of folate, to ensure adequacy of other nutrients (e.g. iron) required during pregnancy. Three-hour fasting venous blood samples will be collected at baseline and endline to measure serum and red blood cell folate, unmetabolized folic acid and other related biomarkers. Women will be given the option to continue supplementing until 1-week postpartum, and provide a small (3mL) breastmilk sample and blood sample in order to measure differences in folates in breastmilk and postpartum folate. These pilot data will be used to inform a definitive trial regarding the most effective form of folate supplementation for mothers and their babies.
The presence of circulating tumor cells (CTCs) in the blood of prostate cancer patients has been shown to be an important indicator of metastatic disease and poor prognosis. Additionally, changes in CTC number throughout treatment have been demonstrated to reflect therapy response. However, the CellSearch® (Menarini-Silicon Biosystems) is the only FDA- and Health Canada-cleared CTC platform available at the present time, and is thus considered the current "gold standard" for clinical CTC analysis. Notably, CTCs are undetectable in ~35% of metastatic CRPC patients. This suggests that either CTCs are truly not present in >1/3 of patients with advanced metastatic disease; and/or that CTCs are present but not detectable as they do not meet the standard CellSearch® definition of CTCs. Given the accumulating evidence that prostate cancer cells can lose epithelial characteristics as they evolve towards a more metastatic phenotype, the investigators believe the latter scenario is most likely. The epithelial-to-mesenchymal transition (EMT) is a critical process during embryonic development and cancer metastasis. Although the role of androgen receptor (AR) signaling in EMT is poorly understood, studies have also demonstrated that EMT may be facilitated by androgen deprivation, castration-resistance, and/or disruption of androgen signaling. Importantly, several clinical studies have demonstrated that CTCs with a purely mesenchymal phenotype are undetectable by CellSearch®, but that the presence of mesenchymal marker expression on CTCs with a hybrid epithelial-mesenchymal phenotype is indicative of poor prognosis. In addition, previous pre-clinical data from the Allan laboratory has demonstrated that in animal models, prostate cancers with a mesenchymal phenotype shed greater numbers of CTCs more quickly and with greater metastatic capacity than those with an epithelial phenotype. Notably, the clinically-used CellSearch®-based assay captured the majority of CTCs shed during early-stage disease in vivo, and only after the establishment of metastases were a significant number of undetectable CTCs present. This suggests that current clinical assays may be limiting ability to capitalize on the full potential of CTCs, and that a greater understanding of CTC biology is necessary in order to guide future technology development and translation to the clinic.
The aim of this study is to determine if virologically suppressed Human Immunodeficiency Virus (HIV) Type 1 infected adults on a current antiretroviral regimen (CAR) (including 2 nucleoside reverse transcriptase inhibitors [NRTIs] plus a third agent) remain suppressed upon switching to dolutegravir/lamivudine (DTG/3TC) fixed dose combination (FDC). The main objective of the study is to demonstrate the non-inferior antiviral activity of switching to DTG/3TC FDC once daily compared to continuation of CAR over 48 weeks in virologically suppressed adults living with HIV-1. The study will also evaluate information regarding the safety and health related quality of life. The study will include Screening Phase (up to 28 days), a Randomization Phase (up to Week 52) and a Continuation Phase (post Week 52). The Continuation Phase is not applicable for participants in Sweden and Denmark. Approximately 490 participants will be randomized in 1:1 ratio to receive DTG/3TC FDC once daily for up to 52 weeks or continue their CAR for 52 weeks. Participants in the DTG/3TC FDC arm who successfully complete up to 52 weeks of treatment will have the opportunity to continue receiving DTG/3TC FDC once daily in Continuation Phase.
Background: Intestinal resections are commonly performed in the pediatric population. Perfusion of the bowel is one of the most important factors determining the viability of an intestinal anastomosis. Up to date, no ideal method to assess intestinal perfusion has proven its superiority. Objectives: Primary: The aim of this study is to establish the feasibility and impact of the use of indocyanine green technology on intestinal resection margins during elective and emergency pediatric surgeries. Secondary: The secondary outcomes of interest include collection of adverse events and difficulties encountered with the use of the indocyanine green (ICG) technology. Postoperative surgical complications will also be recorded. Study Design: An open observational clinical study will be performed by using a clinical drug (indocyanine green) and medical device (SPY Fluorescence Imaging) to assess intraoperatively intestinal perfusion in a specific pediatric population.
Epilepsy is a debilitating condition characterized by spontaneous, unprovoked seizures. Up to 80% of children with epilepsy (CWE) may face cognitive, psychiatric, and/or behavioral comorbidities with significant unmet mental health needs. Mindfulness-based interventions may provide an ideal vector to target unmet mental healthcare needs in patients with epilepsy and their families. The investigators propose the Making Mindfulness Matter© (M3) program as an intervention to improve health related quality of life and mental-health for CWE and their parents. M3 is live-online parent and child program that incorporates mindful awareness, social-emotional learning skills, neuroscience, and positive psychology. This pilot RCT is needed to refine the implementation of the intervention to families with a child with epilepsy, and collect information pertaining to the feasibility and effectiveness of the intervention in preparation for a subsequent multi-centred trial across Canada. Note: Due to COVID-19, the format has been modified for online delivery (from community-based) and the intervention has been restarted.
The present study aims to investigate the effect of a standardized liquid breakfast containing a food grade propionate colon release form on ad libitum eating and appetite perception in healthy overweight humans using a double-blinded, randomized, cross-over study design
Eleven men with myotonic dystrophy type 1 (DM1) underwent a 12-week lower-limb strength training program. The training program consisted of 3 series of 6 to 8 maximal repetitions of 5 different exercises: Leg extension, leg press, hip abduction, squat and plantar flexion. Training sessions were closely supervised and took place twice a week. It is hypothesised that the training program will induce muscular hypertrophy despite the genetic defect. The training program should also have positive effects on function. The participants were evaluated at baseline, week 6, week 12, month 6 and month 9 to see the effects of the training program and if these effects are maintained over time.
