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.
Growing evidence has supported rapid and robust antidepressant effects with subanesthetic doses of intravenous (IV) ketamine for treatment resistant depression (TRD). However, no completed or ongoing RCTs have evaluated the effects of repeated doses of IV ketamine for a homogenous sample of patients with treatment-resistant bipolar disorder depression (TRBD). The primary research goal is to determine the acute antidepressant efficacy, safety and tolerability of repeated sub-anesthetic maintenance doses of IV ketamine in, over a period of twelve weeks. Open-label ketamine infusions will be provided on a flexible schedule (every 2-4 weeks) with flexible dosing (0.5-1.0mg/kg over 40 minutes) titrated to optimize benefits, while minimizing the dosage and frequency over a 12-week extension period. All patients participating in this open-label study will have completed an acute course of infusions in a parent two-site, phase II, double-blinded midazolam-controlled RCT trial. In addition to this acute course of four infusions, a maximum of six infusions will be provided over the 12-week period. Secondary aims include evaluating effects of IV ketamine on suicidal ideations, quality of life, function and duration of effects. Herein, a two-site (University Health Network and Ontario Shores Centre for Mental Health Sciences), single-arm, open label, 12-week extension trial evaluating the effects of flexibly-dosed adjunctive ketamine infusions for TRBD to maintain antidepressant effects in participants who achieved an antidepressant response (MADRS decrease by >50%) or remission (MADRS < 12) following an acute course of four ketamine infusions is proposed. The primary outcome will be Montgomery-Åsberg Depression Rating Scale (MADRS) scores, determining by a linear mixed model from baseline to week 12. Secondary outcomes include evaluating response and remission rates, safety, tolerability (including treatment-emergent mania), and effects on suicidality, anxiety, quality of life, function and the duration of effects.
The investigators are studying a new rehabilitation treatment for individuals trying to recover walking after spinal cord injury (SCI). The investigators will test conditions in the blood and spinal fluid to determine the best time to start this new training program. This will include checking for certain features called biomarkers by testing participants' spinal fluid and blood and compare these features to individuals without SCI. These features will help investigators determine when to start the new training program, either right away or waiting for 3 months. The new training program uses walking downhill on a slight slope on a treadmill while muscles that are not working normally are stimulated to contract using low levels of electricity. Adding this stimulation will allow people to practice walking and other skills even though full muscle control has not recovered. This new program will be in addition to any other rehabilitation therapy and will not replace standard rehabilitation. The hope is to see if downhill training with muscle stimulation, when delivered at the most ideal time, will improve trunk and leg movement, walking, and overall function. This recovery of movement and function will be compared to people with SCI receiving standard rehabilitation alone. Certain regions of the brain and spinal cord will also be studied using MRI scans to determine if these are affected by the training and compare to individuals without SCI. The total length of the study for SCI participants will be up to 16 weeks if in the standard of care group and up to 33 weeks if in the trained group. Healthy control participants will be involved for 1-2 visits.
The purpose of this study is to evaluate the safety and effectiveness of triplet therapy of nivolumab, relatlimab and bevacizumab versus nivolumab and bevacizumab in participants with untreated advanced/metastatic hepatocellular carcinoma (HCC).
Chronic headaches are a major cause of disability among adolescents. Cannabis products have supported the management of headaches in adults and may play a role in pediatric chronic pain. We propose a multisite, open-label, tolerability study conducted across three centers in Canada of Cannabidiol-enriched Cannabis Herbal Extract in adolescents (ages 14 to 17 years old) with chronic headaches. The study includes a one month baseline assessment, four months of escalating treatment doses and a weaning period. Our primary outcome is tolerability defined as the number and severity of reported adverse events.
One significant challenge to non-invasive ventilation (NIV) use in children is finding masks to fit a wide range of growing shapes and sizes. While the technology has improved with development of masks specifically for children, the range of options remains limited. Given the smaller size relative to adults, craniofacial abnormalities and craniofacial differences are more likely to compromise mask fit for children. A poor mask fit is uncomfortable, alters delivery of airway pressure, and, in some children, leads to failure of NIV and the need for surgical insertion of an airway in the neck to deliver positive airway pressure through a tracheostomy. This makes expanding the technology to deliver NIV vital and custom NIV masks an exciting solution.In this study, this study will enroll children who are established on long-term NIV with at least some use within 3 months of starting this therapy but who have non-optimal adherence. After consenting to participate and completing demographic and health questionnaire, participants will undergo a facial scan using stereophotogrammetry. This scan will be imported into a computer-aided design software to create a NIV mask customized to the individual face. The steps of mask testing will include: i) Bench testing to compare the leak and comfort parameters of the current commercial mask used by the participant to the custom mask: ii) Efficacy of treatment as measured by polysomonography iii) NIV compliance from machine downloads; iv) Questionnaires to assess the subjective comfort, fit, and adverse events Finally, participants and their parents/guardian will be asked which mask they prefer and why.
The primary aim is to test whether abatacept, as compared to placebo, is associated with a reduction in major adverse cardiac events (MACE) among participants hospitalized with myocarditis secondary to an immune checkpoint inhibitor (ICI). The primary outcome, MACE, is a composite of first occurrence of cardiovascular death, non-fatal sudden cardiac arrest, cardiogenic shock, significant ventricular arrythmias, significant bradyarrythmias, or incident heart failure.
This is a global, prospective, multi-center study that is designed to assess the long-term safety and efficacy of OAV101 in patients who participated in an OAV101 clinical trial. The assessments of safety and efficacy in Study COAV101A12308 will continue for 15 years from the date of OAV101 administration in the previous clinical trial.
This is a pilot 3 center prospective study of pediatric renal kidney recipients undergoing protocol biopsies examining the performance of the TruGraf gene expression test in children and adolescents.
There is likely a role for using anti-fibrotic medications in patients with myositis-associated interstitial lung disease (MA-ILD) to slow down disease progression, especially in patients who have fibrotic and progressive disease. These patients however are currently being excluded from clinical trials of anti-fibrotic agents in progressive ILD because of the concomitant use of immunosuppression. The benefit of anti-fibrotic agents is being assessed in other rheumatic diseases and should be assessed in MA-ILD as well. They are a unique group of patients with a heterogeneous disease, and are much more frequently on concomitant immune-modulating therapy. As such, they should be studied on their own in separate clinical trials, and the use of nintedanib should be studied as an addition to standard of care immunosuppression. The objective of this study is to assess safety and tolerability of nintedanib in patients with MA-ILD.
