NCT ID: NCT02012218 Completed - Clinical trials for Major Depressive Disorder (MDD)

Brexpiprazole as Adjunctive Therapy With Major Depressive Disorder and an Inadequate Response to Previous Adjunctive Therapy

Start date: November 2013
Phase: Phase 3
Study type: Interventional

The objectives of this exploratory trial are to evaluate the efficacy, safety, and subjects' subjective satisfaction when switching to adjunctive brexpiprazole in subjects with MDD who have responded inadequately to preceding adjunctive drug therapy.

NCT ID: NCT01912196 Completed - Clinical trials for Major Depressive Disorder (MDD)

Add-On Study of MSI-195 (S-Adenosyl-L-Methionine, SAMe) for Patients With Major Depressive Disorder (MDD)

Start date: October 2013
Phase: Phase 2
Study type: Interventional

The purpose of this study is to determine the efficacy and safety of 800 mg MSI-195 in reducing symptoms of depression in Major Depressive Disorder (MDD)patients with inadequate response to current antidepressant therapy.

NCT ID: NCT01790919 Completed - Clinical trials for Major Depressive Disorder (MDD)

Improving Depression Outcome by Enhancing Memory for Cognitive Therapy

Start date: February 2013
Phase: Phase 2
Study type: Interventional

Existing drug and talking therapies for major depressive disorder (MDD) fail to produce complete recovery. This study will determine if substantial improvements to one of the most promising therapies, cognitive therapy (CT), can be achieved by administering a carefully designed procedure to improve memory for the content of CT sessions. This is important because (a) memory deficits are common in MDD patients and (b) each CT therapy session typically covers a complex array of topics and various skills are taught.

NCT ID: NCT01701258 Completed - Clinical trials for Major Depressive Disorder (MDD)

An Investigation of Early Life Stress and Depression

Start date: August 2013
Phase: Phase 1
Study type: Interventional

The purpose of this study is to investigate brain pathways within adult females (with a history of CSA that occurred between the ages of 5-14) with and without a current diagnosis of major depressive disorder (MDD). Hypotheses: The CSA/MDD participants will be characterized by (1) reduced reward responsiveness and prefrontal cortex activity, but increased cortisol levels, (2) reduced dopamine activity, and (3) reduced dopamine transporter binding. The over-arching purpose of the study is to (1) identify individuals at risk for psychopathology and maladaptive behavior, (2) prevent re-victimization, and (3) develop more targeted therapeutic interventions.

NCT ID: NCT01683019 Completed - Clinical trials for Major Depressive Disorder (MDD)

Feasibility Study to Test Clinical Efficacy of Low Energy AC Magnetic Field to Treat Major Depression

Start date: June 2008
Phase: N/A
Study type: Interventional

This feasibility study investigates effects of EEG-based low frequency, low emission magnetic cortical stimulation in comparison to a sham treatment in subjects with moderate to severe depressive disorder.

NCT ID: NCT01594996 Completed - Clinical trials for Major Depressive Disorder (MDD)

European Drug Utilization Study

EUDUS
Start date: April 24, 2012
Phase: N/A
Study type: Observational

The purpose of this retrospective observational study is to evaluate the characteristics of patients receiving Seroquel XR as treatment for their Major Depressive Disorder. The study will also investigate how the medication is used for these patients and if there are any differences in drug utilisation between the included countries. The study is observing patients initiating Seroquel XR during a 9 month period corresponding to 3 to 12 months following the launch of the product in each country for the MDD indication. A drug utilisation questionnaire will be used to collect study data from patients' medical records.

NCT ID: NCT01477203 Completed - Anxiety Disorder Clinical Trials

Multimodal Assessment of Neurobiological Markers for Psychiatric Disorders

MAN-BIOPSY
Start date: November 2011
Phase: Phase 4
Study type: Interventional

MAN-BIOPSY pursues the concrete research question whether novel biological and psycho-physiological clusters or categories can be defined to improve treatment and minimize side effects in psychiatry, based on a synopsis of physiological, behavioural, genetic and endocrinological parameters. One major aspect of our research approach is its focuses on the identification of dysfunctions in fundamental information processing mechanisms and neurocomputational mechanisms, and is not restricted to symptom-oriented tasks. The main objectives of MAN-BIOPSY are therefore - to identify biological and psycho-physiological parameters for major depressive disorders and anxiety disorders, and - to identify predictive markers for treatment response and type/severity of side effects for these disorders.

NCT ID: NCT01253421 Completed - Clinical trials for Major Depressive Disorder (MDD)

The Effects of Dopamine on Reward Processing

Start date: February 2012
Phase: Phase 1
Study type: Interventional

The purpose of this study is to evaluate the effects of a single low dose of the D2/D3 antagonist amisulpride on reward processing. More generally, this study will test the role of dopamine (a naturally occurring brain chemical) in depression. Hypotheses: Administration of a single low dose of the D2/D3 antagonist amisulpride will (1) improve performance in a behavioral task assessing learning from feedback and (2) boost activation in reward-related brain regions.

NCT ID: NCT01187407 Completed - Clinical trials for Major Depressive Disorder (MDD)

A Study of Flexible or Fixed Dose LY2216684 as Adjunctive Treatment for Participants With Major Depressive Disorder Who Have Had a Partial Response to Selective Serotonin Reuptake Inhibitor (SSRI) Treatment

Start date: March 2011
Phase: Phase 3
Study type: Interventional

The purpose of this study is to assess if LY2216684 (flexible dose of 12 to 18 milligrams [mg] or fixed dose of 6 mg once daily) is superior to placebo once daily in the adjunctive treatment of participants with Major Depressive Disorder (MDD) who were identified as partial responders to an adequate course of treatment with a selective serotonin reuptake inhibitor (SSRI) during an 8-week, double-blind, acute adjunctive treatment phase.

NCT ID: NCT00960986 Completed - Clinical trials for Major Depressive Disorder (MDD)

A Duloxetine Dosing Strategy Study in Korean Patients With Major Depressive Disorder

Start date: August 2009
Phase: Phase 4
Study type: Interventional

The purpose of this study is to assess nausea severity in response to four different drug dosing strategies of Duloxetine (30 mg with food, 60 mg with food, 30 mg without food, and 60 mg without food) in Korean patients with major depressive disorder (MDD).
