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: NCT01123707 Terminated - Clinical trials for Major Depressive Disorder (MDD)

To Assess the Safety and Tolerability of an Oral Aripiprazole/Escitalopram Combination Therapy in Participants With Major Depressive Disorder (MDD)

Start date: November 18, 2010
Phase: Phase 3
Study type: Interventional

This is a multicenter, 52-week, open-label study designed to assess the safety and tolerability of an oral aripiprazole/escitalopram combination therapy in outpatients with major depressive disorder (MDD). Enrollment into the study will be from eligible participants who have completed participation in Protocol 31-08-255 [NCT01111539], 31-08-256 [NCT01111552], or 31-08-263 [NCT01111565] ("rollover" participants).

NCT ID: NCT01111565 Terminated - Clinical trials for Major Depressive Disorder (MDD)

Study to Evaluate the Efficacy, Safety and Tolerability of an Oral Aripiprazole/Escitalopram Combination Therapy in Participants With Major Depressive Disorder (MDD)

Start date: October 4, 2010
Phase: Phase 3
Study type: Interventional

This will be a multicenter, randomized, double-blind study designed to assess the efficacy, safety and tolerability of an oral Aripiprazole/Escitalopram combination therapy in participants with MDD who have demonstrated an incomplete response to a prospective trial of Escitalopram, and report a treatment history for the current MDD episode of an inadequate response to at least one and no more than three adequate trials of an approved antidepressant other than Escitalopram. An inadequate response is defined as less than a 50% reduction in depressive symptom severity as assessed by the participant's self-report on the Massachusetts General Hospital Antidepressant Treatment Response Questionnaire (ATRQ) and evaluated by the investigator as part of the participant's medical and psychiatric history. An adequate trial is defined as an antidepressant treatment for at least 6 weeks duration (or at least 3 weeks for combination treatments) at an approved dose as specified in the ATRQ.

NCT ID: NCT01111552 Terminated - Clinical trials for Major Depressive Disorder (MDD)

Study to Evaluate the Efficacy, Safety and Tolerability of an Oral Aripiprazole/Escitalopram Combination Therapy in Participants With Major Depressive Disorder (MDD)

Start date: July 29, 2010
Phase: Phase 3
Study type: Interventional

This will be a multicenter, randomized, double-blind study designed to assess the efficacy, safety and tolerability of an oral Aripiprazole/Escitalopram combination therapy in participants with MDD who have demonstrated an incomplete response to a prospective trial of Escitalopram, and report a treatment history for the current MDD episode of an inadequate response to at least one and no more than three adequate trials of an approved antidepressant other than Escitalopram. An inadequate response is defined as less than a 50% reduction in depressive symptom severity as assessed by the participant's self-report on the Massachusetts General Hospital Antidepressant Treatment Response Questionnaire (ATRQ) and evaluated by the investigator as part of the participant's medical and psychiatric history. An adequate trial is defined as an antidepressant treatment for at least 6 weeks duration (or at least 3 weeks for combination treatments) at an approved dose as specified in the ATRQ.

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).

NCT ID: NCT00958204 Completed - Clinical trials for Major Depressive Disorder (MDD)

Light, Ion, and Fluoxetine Efficacy (LIFE) in Depression

Start date: October 2009
Phase: Phase 3
Study type: Interventional

This study will investigate the additional benefits of light and ion therapy as added treatments to an antidepressant (fluoxetine) in subjects with major depressive disorder (MDD), versus treatment with fluoxetine alone. Outcomes will include depressive symptom rating scales and measures of quality of life, work absence and productivity, and use of health care services. The primary hypotheses are that, in patients with nonseasonal major depressive disorder (MDD) of at least moderate severity: 1) bright light therapy or negative ion therapy will be superior to a placebo condition in reducing symptoms of depression, and 2) the combination of fluoxetine and either bright light or negative ion therapy is more effective than either monotherapy condition.

NCT ID: NCT00839176 Completed - Clinical trials for Major Depressive Disorder (MDD)

Efficacy Study of RX-10100 to Treat Major Depressive Disorder (MDD)

Start date: January 2009
Phase: Phase 2
Study type: Interventional

The primary objective of this Phase IIa trial is to determine the effective dose and treatment period for an upcoming RX-10100 Phase IIb trial in subjects with major depression disorder (MDD). The secondary objectives of this trial are to evaluate the safety and quality of life in subjects with MDD receiving RX-10100 treatment.
