Active clinical trials for "Depressive Disorder, Major"

Testing an mHealth mobile interventionist texting program on illness management.

The purpose of the study is to describe the association/correlation between change in patient-reported cognitive symptoms and work productivity in gainfully employed patients receiving vortioxetine for a Major Depressive Episode (MDE).

Mood journaling is a cornerstone of self-management in major depressive disorder (MDD). Research over the last decade has shown that electronic mood journals are superior to paper ones. One potential advantage of mental health telemetry (MHT), which use cell phones to collect mood journal data, is that electronic journal data can easily be converted into graphical records, allowing people living with MDD to readily spot trends, correlations, or patterns in ways that would be quite challenging using paper diaries. This information should make it easier to recognize and evaluate changes in mental health status -- the first two steps in the process of self-management. The investigators will develop and deploy a visualization module for patients with which to explore their own MHT data sets on the same cell phones which they record their journals, and test the investigators hypotheses that their enhanced MHT system will (i) improve patients' ability to self-manage MDD and (ii) enhance their quality-of-life. The study is a non-randomized, un-blinded, A-B-A' (modified single-subject withdrawal design, with user choice of treatment or withdrawal in the A' stage) study, to explore the utility of MHT as a tool for enhancing self-management and QoL for persons living with MDD. The aims of this study are to explore the impact of MHT on subjects' self-management and QoL, and to gauge participants' perceptions of MHT's utility.

To demonstrate that the antidepressant activity of ETS6103 is not inferior to amitriptyline in subjects who have an unsatisfactory response to / are resistant to treatment with SSRIs.

The investigators hypothesized that combined pharmacotherapy using adjunctive aripiprazole of standard antidepressants would be associated with improved depression response in Major depressive disorder, especially in Quality of life. The investigators compare the mean changes in the quality of life between before add-on and 8 weeks treatment of aripiprazole and between before add-on and 6 weeks treatment of aripiprazole.

This is a 6-week comparison of asenapine versus placebo as an add-on to ongoing antidepressant treatment in patients with major depression who have not had a complete therapeutic response to treatment with the antidepressant alone. The investigators hypothesize that added asenapine will produce greater reductions in depression than will added placebo.

Predictive factors and biomarkers of response to antidepressants in major depressive disorder are scarce. Beta-arrestins are proteins which inhibit G Protein Coupled Receptors and desensitize serotonergic and dopaminergic receptors. The study hypothesis is that Beta-arrestins 1 and 2 are predictive factors and biomarkers of response to antidepressants in major depressive disorder. In a controlled prospective open naturalistic monocentric 3-month study, 60 patients with a major depressive disorder requiring a treatment with venlafaxine will be included and assessed before treatment, 1 month and 3 months post-treatment. 20 controlled healthy subjects matched for age and gender will also be assessed. The Beta-arrestin pathway will be assessed using genetic polymorphisms, Peripheral Blood Mononuclear Cell measures and functional pathway. Antidepressant response will be assessed using depression scales, olfaction and memory as surrogate markers of neurogenesis.

Primary: to identify physiologic indicators of venlafaxine treatment response using quantitative EEG (QEEG) cordance, and to determine if cordance changes are specifically associated with response to venlafaxine; Secondary: to determine if cordance changes early in the course (i.e., prior to improvement in clinical symptoms) of venlafaxine (or another antidepressant if venlafaxine is not clinically indicated for a particular patient) are predictive of later clinical response.

This is a prospective open label study of acute and maintenance treatment of MDD. The acute phase consists of daily treatments for 4 weeks. maintenance will be twice a week for eight weeks followed by 10 weeks of once a week treatments.

The purpose of this study is to find out what parts of the brain have increased or decreased activity when people are depressed and how antidepressant medicine changes this activity in depressed patients. The genetic samples collected are to look at variation in a gene (serotonin transporter gene), which affects the functioning of the chemical serotonin in the brain
