NRX101 Glx Biomarker Validation Study
Bipolar DepressionSuicidal IdeationSubnormal level of Glutamate+Glutamine (Glx) in the Anterior Cingulate Cortex (ACC) of the brain has been associated with depression and PTSD. Similarly, interventions that increase the level of Glx in the brain, specifically electroconvulsive therapy (ECT) and intravenous ketamine infusion have been associated with a rapid decrease in depression and suicidal ideation. This effect has been demonstrated in a dose-dependent manner in randomized clinical assessments. D-cycloserine, a glycine site modulator of NMDA receptor function has been demonstrated to increase Glx in the ACC of normal volunteers. The purpose of this study is to determine whether NRX-101, an experimental drug containing a fixed dose combination of D-cycloserine and lurasidone (1) raises Glx by a greater amount than either placebo or lurasidone alone in patients with bipolar depression, and (2) whether that elevation in Glx is correlated with a decrease in depression.

Trial of the Rapid Antisuicidal Effects of Intranasal Ketamine in Comorbid Depression and Alcohol...
Suicidal IdeationDepression1 moreThis project aims to evaluate the potential rapid and sustained antisuicidal and antidepressant effects of a single intranasal dose of ketamine in inpatients during a mood episode in Major Depressive Disorder (MDD) or Bipolar Disorder (BD) with or without comorbid recent abuse of alcohol.

Cognitive AppRoaches to coMbatting Suicidality
PsychosisSuicide Prevention1 moreThis is a randomised controlled trial which investigates the effectiveness of CARMS (Cognitive AppRoaches to coMbatting Suicidality) therapy in reducing suicidal thoughts and how well CARMS works in practice within the NHS. The trial will compare two groups of people with psychosis who are using NHS mental health services. One group will carry on with their usual treatment. The other group will be offered 24 weekly sessions of CARMS therapy, plus their usual treatment.

Establishing Efficacy of an Inpatient Intervention and Phone App to Reduce Suicidal Risk
Suicidal IdeationSuicide1 moreIn this 2-site study, University of Texas Southwestern Medical Center (UTSW) and Western Psychiatric Institute and Clinic (WPIC), the investigators will conduct a randomized clinical trial (RCT) in 240 psychiatrically hospitalized suicidal adolescents, examining the single and additive effects of two components of an inpatient unit intervention for suicidal adolescents, As Safe As Possible (ASAP), which focuses on emotion regulation and safety planning, and an emotion regulation/safety plan phone app (BRITE).

A Policy Relevant US Trauma Care System Pragmatic Trial for PTSD and Comorbidity
Posttraumatic Stress DisorderDepression9 moreThe overarching goal of this UH2-UH3 proposal is to work with the NIH Health Care Systems Research Collaboratory to develop and implement a large scale, cluster randomized pragmatic clinical trial demonstration project that directly informs national trauma care system policy targeting injured patients with presentations of Posttraumatic Stress Disorder (PTSD) and related comorbidity. Each year in the United States (US), over 30 million individuals present to trauma centers, emergency departments, and other acute care medical settings for the treatment of physical injuries. Multiple chronic conditions including enduring PTSD, alcohol and drug use problems, depression and associated suicidal ideation, pain and somatic symptom amplification, and chronic medical conditions (e.g., hypertension, coronary artery disease, diabetes, and pulmonary diseases) are endemic among physical trauma survivors with and without traumatic brain injuries (TBI). Evidence-based, collaborative care/care management treatment models for PTSD and related comorbidities exist. These care management models have the potential to be flexibly implemented in order to prevent the development of chronic PTSD and depressive symptoms, alcohol use problems, and enduring physical disability in survivors of both TBI and non-TBI injuries; care management models may also be effective in mitigating the impact of the acute injury event on symptom exacerbations in the large subpopulation of injury survivors who already carry a substantial pre-injury burden of multiple chronic medical conditions.

Reconnecting: Improving Interoception to Reduce Suicidal Ideation in the Military
Suicidal IdeationInteroceptionBackground: Interoception is defined as the "sense of the physiological condition of the entire body" and is crucial for recognizing emotions and sensations (e.g., hunger, temperature, pain) and responding accordingly. The investigator's lab has conducted several independent studies and two pilot studies that support the hypothesis that disrupted interoception leads one to be disconnected from the body, and thus more able to harm the body should one desire to do so. Research suggests that interoceptive deficits may not only differentiate those who are thinking about suicide from those who engage in suicidal behavior, but it may also provide information about who is at imminent risk for suicidal behavior. The identification of novel, short-term risk factors, like interoceptive deficits, allows for the development of new treatment applications for suicide, which is important for several reasons: 1) suicide rates have increased in recent years, especially among military populations, and 2) existing treatment approaches are often ineffective, lengthy, expensive, or impractical for large-scale dissemination. This project evaluates a novel, brief intervention for interoceptive deficits and suicidal behavior with the potential to be acceptable and feasible for a military population.

A Mindfulness-Based Cognitive Therapy for Suicidal Patients
Suicidal IdeationSuicide AttemptThe main goal of this study is to evaluate the effectiveness ofMindfulness-Based Cognitive Therapy aimed at reducing suicidality in adults. This will test the effectiveness by studying the effect on suicidal ideation and related outcomes, compared to Treatment As Usual. The study is a multicentre randomized controlled trial conducted in out-patient Flemish mental healthcare facilities.

Digital Dialectical Behavioral Therapy (d-DBT) Skills for Acute Suicidality in Psychiatric Inpatients...
Suicidal IdeationSuicidality (ideation about taking one's life, suicide plans, and attempts) is a major public health concern in Ontario and worldwide. Psychiatric inpatients with suicidality represent a group that is high-risk for subsequent suicide. Current standard-care for suicidal psychiatric inpatients focuses on containment of risk and indirect treatment of suicidality by treating any underlying mental disorder. Though there is evidence that addressing suicidality directly is more effective than an indirect approach, there are limited evidence based treatments that target suicidality. Furthermore, there are few high-quality studies that have included inpatients. Psychotherapeutic interventions are under-utilized for inpatients and COVID-19 has further widened this gap given attempts by hospitals to reduce face-to-face contact with patients. Digital psychotherapy interventions have the ability to bridge this gap given their lower cost, ease of dissemination, acceptability by patients, and effectiveness. To our knowledge, there are no studies that have assessed the feasibility, acceptability and effectiveness of digital interventions for suicidal inpatients. Our study is a feasibility trial of a previously studied digital Dialectical Behavioural Therapy (d-DBT) skills intervention in suicidal psychiatric inpatients. The study is a two arm randomized parallel group-controlled trial, 6-10 day, flexible timeline, randomized feasibility trial of a d-DBT skills intervention added to standard care for patients admitted to psychiatric inpatient units with suicidality. There will be 20 patients who will receive the intervention in addition to standard care and 20 patients who will receive standard care alone. There will also be a 4 week follow-up after discharge from hospital. Participants will be admitted for psychiatric care at the Complex and Critical Care Units, Centre for Addiction and Mental Health (CAMH), Toronto.

Men and Providers Preventing Suicide (MAPS)
Suicidal IntentionSuicidal Ideation2 moreThis study will determine if suicidal middle-aged men who use a personalized computer program addressing suicide risk before a primary care visit are more likely to discuss suicide and accept treatment, reducing their suicide preparatory behaviors and thoughts.This is important because half of all men who die by suicide visit primary care within a month of death, yet few broach the topic, missing chances for prevention.

Magnetic Seizure Therapy for the Treatment of Borderline Personality Disorder
Borderline Personality DisorderSuicide is a major public health crisis for which effective new interventions are needed. An innovative new brain stimulation technique called magnetic seizure therapy (MST) shows promise for treating suicidal thinking in chronically depressed individuals. Using a high-risk cohort of suicidal patients with borderline personality disorder (BPD) and treatment resistant major depressive disorder (MDD), this study will evaluate the effectiveness of MST for reducing suicidality and depressive symptoms in an open-label clinical trial of up to 15 treatment sessions. Based on research showing that functioning of the dorsolateral prefrontal cortex (DLPFC) may be disrupted in BPD and place individuals at risk for suicide, the DLPFC will be targeted for stimulation. Moderate-to-highly suicidal patients with BPD beginning dialectical behavioural therapy (DBT) will be recruited using a case-control design, comparing individuals receiving MST and DBT with matched patient control group receiving DBT alone.
