Depression Clinical Trials in Canada

This study evaluates the effectiveness of additional content on loneliness offered alongside the Wellbeing Course - an internet-delivered cognitive behavioral therapy (ICBT) intervention for symptoms of depression and anxiety- in improving treatment outcomes for individuals with elevated scores on loneliness seeking treatment for depression and anxiety at a routine care online therapy clinic (the Online Therapy Unit). In this partially randomized control trial, the investigators aim to contribute to the literature by examining whether providing additional content on loneliness alongside the Wellbeing Course enhances engagement, satisfaction, and treatment outcomes among clients experiencing frequent loneliness compared to those completing only the Wellbeing Course. Over 8 weeks, participants will review course materials (with the addition of the loneliness content for those assigned to the loneliness content condition) online and complete questionnaires assessing changes in various outcomes over time.

Dialectical behavior therapy (DBT) is a comprehensive, third-wave psychological intervention designed for patients with complex and severe behavioral, emotional, and interpersonal dysfunction. DBT has since been adapted to shorter, briefer, "skills training" formats, which have been effective for a number of mild-to-moderate mental health conditions, including depression and anxiety. Moreover, internet-delivered formats of DBT (iDBT) have similarly started to build support for their effectiveness, although there are fewer studies on digital formats. One study found that over 12 weeks, iDBT was deemed acceptable (e.g., 50% of participants were still active after 4 weeks) and there were improvements in multiple symptom domains, such as depression, anxiety, suicidality, functional disability, as well as alcohol and substance dependence. In the current study, the investigators will examine the feasibility, acceptability, and potential efficacy of a new iDBT intervention, packaged as an online e-learning skills course, with adult participants. The study is a pilot trial as iDBT has never been tested in this format through formal research. Thus, this pilot study aims to examine whether this course is usable, practical, and potentially useful to others in the future. The investigators will recruit up to 40 individuals with mild-to-moderate depression and anxiety for an 8-week study. Following a phone screen to determine eligibility, participants will complete a baseline session where they will provide consent, complete a brief interview and questionnaires, and register for the e-learning skills course. Over the course of 8 weeks, participants will be exposed to material adapted from a DBT manual in a self-guided manner. Participants will complete follow-up assessments at 4 and 8 weeks. Read Less

While effective interventions for depression exist, their success rates are unsatisfactory and their provision is haphazard. The Canadian Depression Research and Intervention Network (CDRIN) Maritimes Depression Hub will improve the delivery of care and the quality of outcomes for youths, adults and seniors with depression across the Maritimes. The investigators will establish an integrated system of assessment, treatment, research and education related to depression with the active involvement of those with lived experience. The establishment of a patient registry is a key step that will facilitate evaluation and reform of current services, integration of patient choice and community resources into treatment programs, monitoring long-term outcomes, and development of more effective treatment approaches through research. The registry will facilitate research that will include validation of new diagnostic and outcome measurement tools, low-cost clinical trials and collaborative projects with national and international partners. Educational programs will involve training the next generation of researchers, those with lived experience, clinicians, and health system managers in critical appraisal and will facilitate their involvement in research. The registry, the proposed systematic measurement of outcomes and the broad dissemination of information and skills will improve the quality of research and of care as well as the experience of patients and their families. The need for a registry: It is increasingly recognized that major advances in the treatment of mental disorders will require large scale clinical research. Recently demonstrated ways of completing large-scale research with finite resources include the routine use of electronic health records (EHR), data linkage and randomized registry trial. Use of EHR is the most efficient way of rapidly obtaining large amounts of information. However, EHR cannot completely exclude confounding by indication and other unmeasured variables. Therefore, tests of treatment effects require experimental designs that cannot be replaced by routine health records data. The gold standard for testing the effects of treatment in an unbiased way is the randomized controlled trial (RCT), where measured and unmeasured confounders are balanced through the randomization process and any remaining confounding is due to chance alone. RCTs are valued as the highest level of evidence, but are costly and take significant time to be completed, partly because of the need to screen a large group of individuals to identify eligible participants. The most efficient unbiased test of interventions, new treatment modalities and novel ways of treatment delivery is a method that combines EHR use with the randomized controlled trial (RCT) methodology: the randomized registry trial (RRT). The RRT takes advantage of a registry of individuals with available information to identify a large number of individuals suitable for an RCT. The RRT approach is efficient especially if the same information (e.g. diagnosis and treatment history) is used repeatedly for different purposes. The same information can be used for clinical purposes, service improvement and multiple research projects. RRT will allow obtaining answers about the efficacy of new treatments and management strategies significantly faster and at a much lower cost than traditional RCTs. Therefore, the investigators propose to establish a registry that has the capacity to conduct RRTs. The proposed registry will be integrated with similar efforts across Canada. Jointly, this collaborative network of registries will facilitate fast and economical testing of new treatments, which is urgently needed to advance the therapeutic options for people with depression and related conditions.

The TIDE project aims to establish personal indicators for initial treatment choice for youth with first episode depression. Specifically, 100 adolescents and young adults (age 12 to 25) with untreated major depressive disorder of recent onset will be randomly allocated in 1:1 ratio to one of two evidence-based regimens for youth depression: (A) Individual cognitive-behavioural therapy; and (B) Optimized pharmacological treatment with an antidepressant. All participants will be offered active treatment for up to 1 year and follow-up for 2 years to establish short- and long-term outcomes, including change in depressive symptoms, maintenance of remission, core role functioning, achievement of educational, occupational and social milestones, and quality of life. Baseline characteristics including duration of untreated depression, pre-existing anxiety, attention-deficit/hyperactivity disorder, substance use, symptoms of reduced interest and activity, sleep, rhythm and melody of speech, brain function, history of childhood adversity, coping style, repetitive thinking, and family history of depression and bipolar disorder will be tested as potential moderators of outcome. Characteristics that differentially predict outcomes in those allocated to initial cognitive-behavioural therapy and those allocated to initial treatment with antidepressants will be combined into a personalized allocation algorithm.

This study evaluates two Internet-delivered cognitive behavioural therapy (ICBT) interventions: one for symptoms of posttraumatic stress disorder (PTSD) and one for symptoms of anxiety, depression, and PTSD. Both interventions have been tailored for Canadian public safety personnel (PSP). Outcomes of interest include preference for disorder-specific or transdiagnostic care, engagement with the interventions, changes in symptoms and functioning, and strengths and limitations of implementing ICBT with Canadian PSP.

There is growing evidence for the effectiveness of internet-delivered cognitive behaviour therapy (ICBT) for post-secondary students with symptoms of depression and anxiety. In ICBT, clients review structured online content over several weeks to learn strategies and skills to manage their symptoms. Low treatment completion rates remain a concern for post-secondary students, so it is possible that existing treatment protocols do not offer enough flexibility for students' needs and preferences. This trial will examine students' preferences for different course options (fast-track, 5-week, and 8-week) and compare enrollment, adherence, and outcomes of students who pick each of the three options. In all three options, students will receive optional therapist support, in which the assigned therapist only contacts the student on weeks where the student sends the therapist a message. This trial will help inform the delivery of flexible treatment options for post-secondary students in a routine care setting. Read Less

This study evaluates an internet-delivered cognitive behavioural therapy for insomnia (ICBTi) intervention, known as the Sleep Course, within a routine online therapy clinic (the Online Therapy Unit). The Sleep Course will specifically be offered to clients with self-reported sleep difficulties (i.e., falling or staying asleep or waking early) and daytime distress and or impairment. This study aims to replicate the effectiveness and acceptability of the previously evaluated Sleep Course when delivered in Australia. The investigators will also assess uptake and completion rates within the clinic as well as demographic and clinical characteristics of individuals enrolled in the Sleep Course. Read Less

Indigenous youth in Northwestern Ontario who need mental health supports experience longer waits than non-Indigenous youth within the region and when compared to youth in other more urban areas. Limited access and extended waits can exacerbate symptoms, prolong distress, and increase risk for more serious outcomes. Novel, innovative approaches are urgently needed to provide support for Indigenous youth in Northwestern Ontario. In partnership with Dilico Anishinabek Family Care, the investigators are evaluating the impact of a mental health app (JoyPop) as a tool for Indigenous youth who are waiting for mental health services. The JoyPop app was developed to support improved emotion regulation - a key difficulty for youth presenting with mental health challenges. A two-arm randomized controlled trial (RCT) will be used to evaluate the effectiveness of the app compared to usual practice while Indigenous youth are waiting for mental health services. Read Less

Spinal cord injury (SCI) has been shown to be associated with impairment to the autonomic nervous system in the form of reduced activity of a key nerve known as the vagus nerve. As the vagus nerve has an important role in regulating inflammation and is associated with depression, it may represent a key mechanism which contributes to chronic inflammation and depression following SCI. A technique known as transcutaneous auricular vagus nerve stimulation (taVNS) can stimulate the vagus nerve non-invasively through an electrode applied on the skin of the ear. This technique has been shown to effectively reduce inflammation and improve symptoms of depression in other populations without any serious adverse events. However, it has not been assessed in individuals with SCI. The primary objective of this study is to assess the efficacy of taVNS therapy for the treatment of inflammation and depression. Autonomic function as assessed by measures of heart rate variability (HRV) will also be assessed to quantify changes in vagal tone. The study will be conducted over a 2-year period, with 44 individuals with SCI and depression participating. Participants will be randomly assigned to receive either active taVNS or a placebo (sham) treatment over a 30-day period. The researchers will assess changes in depression symptoms, autonomic function (heart rate variability), and biomarkers related to inflammation at baseline and 30-days. Safety and adherence will also be evaluated to confirm the feasibility for long-term use. This study aims to explore a novel and non-invasive treatment strategy for depression in individuals with spinal cord injury. If taVNS is found to be safe, effective, and feasible for SCI patients, it could offer a simple, cost-effective way to address chronic inflammation and depression in this population. Read Less
