ALK33BUP-201: Safety and Tolerability Study of ALKS 33-BUP (ALKS 5461) Administration in Subjects...

Major Depressive Disorder

This is a multicenter, randomized, double-blind, placebo-controlled, parallel, multiple dose study designed to evaluate the safety and tolerability of the co-formulation of ALKS 33 with buprenorphine (ALKS 5461) in subjects with Major Depressive Disorder (MDD) who are inadequately/partially responding to current treatment with a stable dose of a serotonin-selective reuptake inhibitor (SSRI) or serotonin-norepinephrine reuptake inhibitor (SNRI).

Life Goals Collaborative Care to Improve Health Outcomes in Mental Disorders

Bipolar DisorderSchizophrenia3 more

Persons with serious mental illness (SMI) are at increased risk of cardiovascular disease (CVD). The goals of this study are to test a treatment, Life Goals Collaborative Care to help promote health behavior change and improve mental health and physical health-related quality of life, as well as to get feedback from patients and providers on what is needed to help better coordinate the physical and mental health care of these patients.

Pharmacokinetics - Pharmacodynamic Study of HT-2157 in Healthy Subjects and in Patients With Major...

Healthy Volunteers (Part 1)Major Depressive Disorder (Part 2)

This is a two part study. The objective of Part 1 is to evaluate the safety, tolerability, and pharmacokinetics of HT-2157 in healthy normal volunteers Part 2 is a randomized, double-blind, placebo-controlled, multiple (21-day) ascending-dose evaluation of the safety, tolerability, pharmacokinetics, and pharmacodynamics of HT-2157 in patients with major depressive disorder

Slow-wave Sleep Deprivation in Depression

Major Depressive Disorder

Sleep deprivation can acutely reverse depressive symptoms in patients with major depression. Although underlying mechanisms of the antidepressant action in sleep deprivation are unclear, many of these observations can be explained by abnormal slow wave homeostasis. This study will test the prediction that selectively reducing slow waves during sleep (slow wave deprivation; SWD), without disrupting total sleep time, will yield an antidepressant effect.

fMRI Study of Treatment Changes in Major Depression

Major DepressionTreatment

The overall purposes of this research are to determine if Cognitive Behavioral Therapy (CBT) has the same healing effect on the brain for people with depression as traditional antidepressants do, and in comparison to healthy controls with no history of depression, to find out more about the causes of depression including differences in the extent of problems caused by depression. We hypothesize that CBT will have the same healing effect on the brain as antidepressants; that differences in brain activations created by the various tasks and genetic differences will help us understand differences in the type and severity of symptoms among the depressed subjects.

Evaluation of the Safety and Pharmacokinetics of MSI-195 to a Commercial S-Adenosylmethionine

Major Depressive Disorder

This study was a pharmacokinetic and safety evaluation of the S-adenosylmethionine formulation MSI-195, and a commercial comparator. The study was broken into two stages. The first stage was an exploratory single ascending dose design of MSI-195 in 8 healthy normal male volunteers. The second stage was a single dose evaluation, targeting 26 male and female volunteers at set doses of MSI-195 and commercial comparator in a cross-over design followed by a food effect study on MSI-195. Plasma samples were collected and assayed for S-adenosylmethionine. Pharmacokinetic parameters were calculated using that data.

Stress and the Sympathetic Nervous System in Adults With Depression

Major Depressive Disorder

To test our hypotheses, we will enroll healthy adults having no history of mood disorders and adults with major depressive disorder (MDD) having a broad range of depressive symptom severity. After screening, subjects will meet with the research coordinator or an investigator for a discussion, with opportunity for questions, before applicable consent forms are obtained. Daily stress processes will be assessed using an ecological momentary assessment approach for 8 consecutive days. On the last day of the daily stress assessment, we will directly measure muscle sympathetic nerve activity, blood pressure, and heart rate during acute laboratory-based cognitive, emotional, and physiological interventions to induce a stress response. A venous blood sample will be taken for measurements of metabolic and renal health and systemic inflammation. Aim 1: To examine the effect of daily psychosocial stressor exposure on acute sympathetic stress reactivity in MDD. Two stressor exposure indicators will be calculated: stressor frequency (i.e., percentage of interview days during which at least one stressor occurred) and total stress (i.e., total number of stressors reported across all interview days) and will be related to the magnitude of responsiveness to the acute stress interventions. We hypothesize that the slope of this relation will be steeper in adults with MDD compared to healthy non-depressed adults. Aim 2: To determine the relation between negative affective reactivity to daily psychosocial stressor exposure and acute sympathetic stress reactivity in MDD. Negative affective reactivity will be calculated as the change in affect on days when stressors occurred compared to one's typical affect on non-stressor days and will be related to the magnitude of responsiveness to the acute stress interventions. We hypothesize that the slope of this relation will be steeper in adults with MDD compared to healthy non-depressed adults.

Gut Feeling: Understanding the Mechanisms Underlying the Antidepressant Properties of Probiotics...

Major Depressive Disorder

Previous research has suggested that probiotics can improve depressive symptoms in patients with Major Depressive Disorder (MDD), particularly when used in addition to antidepressants. The aim of this exploratory pilot study is to improve the investigator's understanding of the mechanisms underlying these effects. This study will assess the effects of an 8-week double-blind placebo-controlled probiotic intervention on the gut microbiome, inflammatory marker levels, brain activity and neurotransmitter levels in patients with MDD and their relationship to changes in mood. This study will also recruit a group of demographically-matched healthy controls for gut microbiome comparison with the MDD group (non-interventional).
