Mental Activity During (TMS) Therapy for Depression
Cognitive ImpairmentThe purpose of the study is to assess the effects of different types of mental activity performed while receiving transcranial magnetic stimulation (TMS) for the treatment of major depressive disorder. Our primary aim for this study is to assess the feasibility of combining TMS and computer based cognitive exercise in patients with major depressive disorder who may also have some degree of cognitive dysfunction, and to formally measure changes in mood and cognition over the course of the study.

Comparative Effectiveness of Pharmacogenomics for Treatment of Depression
Major Depressive DisorderThe overall goal of this study is to assess the effectiveness of a widely available and widely used combinatorial pharmacogenomic (PGx) test for the treatment of major depressive disorder. Pharmacogenomic tests use genetic information to guide medication treatment decisions. The tests inform clinicians and patients of potential gene-drug interactions by analyzing pharmacokinetic (PK) genes (how drugs are metabolized) as well as pharmacodynamic (PD) genes (how drugs work). While combinatorial PGx testing is attractive to clinicians, patients, healthcare systems, and insurers, limited data demonstrate that PGx testing will result in better outcomes compared to evidence-based guideline treatment. Therefore, the investigators will conduct a prospective randomized comparative effectiveness study of best practice guidelines plus combinatorial PGx-guided treatment versus best-practice guideline concordant treatment alone.

A Long-Term Study of Brexpiprazole in Patients With Major Depressive Disorder
Major Depressive DisorderThis trial is a 52-week study to assess the safety of long-term use of brexpiprazole as adjunctive therapy in combination with an antidepressant.

Cognitive Behavioural Therapy for the Treatment of Late Life Depression
Late-life DepressionMajor Depressive Disorder3 moreThis study addresses the unmet medical problem of insufficient treatment of late life depression (LLD). Compared with depression in early adulthood, treatment options of LLD are limited. This trial is the first confirmatory multicentre study to test the efficacy of an LLD-adapted cognitive behavioural therapy (CBT) program. It will test the hypothesis, that LLD-specific cognitive behavioural therapy (CBT) is superior to unspecific supportive intervention (SUI) with regard to reducing symptoms of depression over the course of 6 months. Secondary goals are to test the efficacy of LLD-CBT in comparison with SUI on patient reported outcome in major depressive disorders (PRO-MDD), anxiety, cognition, quality of life, overall health status, sleep and global clinical impression.

CONNECT for Depressed Cannabis Users Trial
Substance AbuseDepressionThe purpose of this study is to test the usefulness of a computer-assisted intervention for depressed cannabis users by combining peer and therapist social network support via Facebook that uses the techniques of cognitive behavioral therapy and motivational enhancement therapy (CBT/MET) to help with relapse prevention skills, reduce cannabis use and depressive symptoms, and improve treatment adherence. All participants will receive 10 weeks of the computer assisted intervention which includes weekly 60 minute (1 hour) sessions. All participants will also be part of a secret Facebook group (CONNECT). The goal of this secret Facebook group is to reinforce the knowledge and skills taught in the computer assisted intervention and to provide social support.

Pramipexole to Target "Anhedonic Depression"
DepressionBipolar4 moreThe heterogeneity of depression suggests that different neurocircuits and pathophysiological mechanisms are involved. Anhedonia - the inability to experience pleasure from, or the lack of motivation to carry out, usually enjoyable activities - is an endophenotype within the depression spectrum, with a distinct pathophysiology of dopaminergic mesolimbic projections. Anhedonia is common in depression and associated with treatment resistance. Pramipexole, an agonist to the dopamine -receptor 3, is an established treatment of Parkinson's disease. Based on its mechanism of action, pramipexole might be efficacious in a subtype of depression characterized by anhedonia and lack of motivation - symptoms linked to dopaminergic hypofunction. In this proof-of-concept pilot study the investigators test the anti-anhedonic and antidepressant effects of add-on pramipexole using an "enriched population study design" including only depressed patients with significant anhedonia. To understand the neurobiology of anhedonia in depression and to identify treatment predictors, the investigators also do assessments of anhedonia-related neurocircuitry using (f)MRI and blood biomarkers.

Optimizing Duration of Therapist-guided Internet-delivered Cognitive Behaviour Therapy
AnxietyDepressionDepression and anxiety are common and prevalent conditions that are frequently under treated. In an attempt to increase timely and accessible psychological treatment, Internet-delivered Cognitive Behaviour Therapy (ICBT) has emerged. ICBT involves delivering therapeutic content to manage depression and or anxiety via structured online lessons. This is often combined with brief therapist guidance, for example once per week for 8 weeks via secure messaging or phone calls. Although outcomes of ICBT are very impressive, there is room for improvement in terms of completion rates and outcomes. Feedback from patients suggest that some patients would prefer longer term support or follow-up care. In this two-factorial randomized controlled trial, the investigators aim to contribute to the literature by examining whether the efficacy of ICBT is improved by offering an extended period of support to clients (from 8 weeks to 12 weeks) and being offered a booster session at 16 weeks after treatment enrollment (yes vs no). Follow-up assessments will be conducted at 8, 16 and 26 weeks after treatment enrollment. Primary outcomes are reduced anxiety and depression. Secondary outcomes include reduced panic, social anxiety, trauma, quality of life, disability, work productivity, and healthcare use.

Evaluation of a Crowd-Powered Web Platform for Depression and Anxiety
DepressionAnxiety100 participants will be enrolled in a two-armed randomized controlled trial of the Accumulated Depression and Anxiety Plans and Treatments (ADAPT) platform which integrates internet Cognitive Behavioral Therapy (iCBT) to determine impact on symptoms of depression and anxiety. This trial will pilot the effectiveness of the ADAPT platform, and evaluate the extent to which the ADAPT platform engages putative targets of personal relevance, skills use, and skills mastery.

Brief Peer Supported webSTAIR Compared to Enhanced Wait List
Post Traumatic Stress DisorderDepression1 moreThis study will enroll 180 Veterans at a 2:1 ratio where 120 Veterans will be enrolled into a brief transdiagnostic peer supported webSTAIR (BPS webSTAIR) and 60 will be supported into Waitlist. The purpose of the study is to assess the efficacy BPS webSTAIR in regard to four outcomes: reduction in PTSD and depression symptoms (measured by the PCL-5 and PHQ-8, respectively) and improvement in emotion regulation and work and social adjustment (measured by the DERS-16 and WSAS, respectively). The active treatment is a 6-session modular treatment that focuses on learning emotion management skills where Particpants will have 10 weeks to complete the treatment. Assessments will occur three times for those in webSTAIR: baseline, post-treatment (10 weeks after randomization) and 8-week follow-up and twice for those on waitlist (baseline and 10 weeks after randomization). It is hypothesized that BPS WebSTAIR will be superior to the Waitlist condition on all four outcomes. Mixed Effects Models will be used to evaluate the outcomes.
