NCT ID: NCT01111539 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 13, 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: NCT01099592 Terminated - Clinical trials for Acute Coronary Syndrome

Antidepressants to Promote Recovery of Cardiac Patients Suffering From Depression

ARCADE
Start date: November 2010
Phase: Phase 4
Study type: Interventional

Depression is frequently seen in cardiac patients. It has been shown that depression often has a negative impact on the course of coronary disease. More recently, research has demonstrated that some antidepressants can be used safely to treat depressed coronary patients. Although the majority of patients improve substantially with antidepressant treatment, a significant proportion do not respond to antidepressants. This project seeks to better understand why depression does not improve equally well in all patients. Ultimately, the hope is to improve the treatments available to people affected by both cardiac disease and depression, and to help select the best type of treatment in advance for each individual based on his or her personal history, and biological characteristics.

NCT ID: NCT01098240 Terminated - Clinical trials for Major Depressive Disorder

A Study Of The Efficacy And Safety Of CP-601,927 Augmentation Of Antidepressant Therapy In Major Depression

Start date: June 14, 2010
Phase: Phase 2
Study type: Interventional

The primary objectives of this study are to: 1) Evaluate the efficacy of CP 601,927 compared to placebo in the augmentation of antidepressant therapy (ADT) in patients with Major Depressive Disorder (MDD) using the Montgomery Asberg Depression Rating Scale (MADRS). 2) Evaluate the safety and tolerability of CP 601,927 in patients with MDD on ADT.

Phase: Phase 4
Study type: Interventional

The primary objectives of the study are to test whether brain Mono Amine Oxidase-A (MAO-A) levels are elevated in patients with treatment-resistant major depression, and to explore whether MAO-A brain levels predict treatment outcome with Mono Amine Oxidase Inhibitor (MAOI) medication in this population.

NCT ID: NCT00955474 Terminated - Clinical trials for Major Depressive Disorder With Psychotic Features

Seroquel Alone Versus Seroquel With an SSRI for Depression With Psychotic Symptoms

Start date: September 2008
Phase: Phase 4
Study type: Interventional

The purpose of this study is to compare the efficacy and tolerability of Seroquel monotherapy for the treatment of Major Depression with Psychotic features with Seroquel plus Selective Serotonin Reuptake Inhibitor.

NCT ID: NCT00926835 Terminated - Clinical trials for Major Depressive Disorder

Effect of Antidepressants on the Treatment for Korean Major Depressive Disorder Patients

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

The primary purpose of this study is to investigate the effectiveness of antidepressants on the treatments for non-psychotic major depressive disorder (MDD) in Korea. The study divides MDD patients into 3 level groups according to their past histories to treatments and compares the effectiveness of various treatment regimens at each level. The treatment level groups are: 1) patients who have never been treated with appropriate medications for their current depressive symptoms before, 2) who received an appropriate SSRI (Selective Serotonin Reuptake Inhibitor) once but did not respond to it, 3) who received two types of SSRI antidepressant treatments without much effects in reducing their depressive symptoms. The first level group will be treated with a single SSRI antidepressant treatment. The second and third level groups, who received SSRI treatment before, will be treated with alternative SSRI antidepressants (switching), combined multiple SSRI treatments (antidepressant combination), or SSRI treatments combined with mood stabilizer or anti-psychotics (augmentation). This study does not use placebos. Patients will visit 5 times for 6 weeks at each level for treatments. Patients will be evaluated for the severity of depressive symptoms, functional level, and side effects at each visit. Afterwards, the investigations will combine to monitor the patients depressive symptoms in every 3 months for the next 24 months. 18 nationwide university hospitals will participate in this study. This multi-site, prospective, and naturalistic study for patients with depression in Korea is a main project of 'Clinical Research Center for Depression' funded by the Ministry for Health, Welfare, and Family Affairs (MIHWAF) in Korea for a highly-qualified research achievement.

NCT ID: NCT00880399 Terminated - Clinical trials for Depressive Disorder, Major

A Randomized, Double-Blind, Parallel-Group, Placebo-Controlled, Fixed Dose Study Evaluating the Efficacy and Safety of Orvepitant in Subjects With Major Depressive Disorder

orvepitant MDD
Start date: March 2009
Phase: Phase 2
Study type: Interventional

This is a 6-week, randomised, multicenter, double-blind, placebo controlled, fixed dose parallel group study to assess the efficacy and safety of orvepitant (30 and 60 mg/day) versus placebo in subjects with a diagnosis of a Major Depressive Disorder, whose symptoms are considered moderate or severe. Following an initial screening visit, subjects fulfilling the study inclusion and exclusion criteria will enter a pre-treatment screening phase to permit evaluation of the laboratory and ECG assessments and to confirm eligibility for inclusion into the study. This screening phase will be a minimum of 7 days, but no longer than 21 days. At the completion of the screening period, eligible subjects will be randomised at the baseline visit to receive either orvepitant 30mg/day, orvepitant 60mg/day or placebo (equal chance of receiving any of the three possible treatments, i.e., a 1:1:1 ratio) for a six-week double-blind treatment phase. Those subjects randomised to receive placebo will receive study medication identical in appearance to that received by subjects assigned to receive orvepitant 30 or 60mg/day. Efficacy will be assessed via standard depression symptom and severity rating scales or questionaires. The Hamilton Depression Rating Scale (HAM-D) will be used as the primary measure. Secondary efficacy endpoints include the Quick Inventory of Depressive Symptomatology (QIDS-SR) and the Clinical Global Impression- Global Improvement and Severity of Illness Scale (CGI-I and CGI-S, respectively). Safety will be assessed by monitoring for adverse events (side effects) and through periodic laboratory evaluations (blood tests), vital signs assessments (e.g., blood pressure, heart rate, temperature) and heart function measurements (electrocardiograms, or ECGs).

NCT ID: NCT00868374 Terminated - Clinical trials for Major Depressive Disorder

Quetiapine Extended Release (XR) Treatment of Major Depressive Disorder With Comorbid Generalized Anxiety Disorder

MDD/GAD
Start date: June 2008
Phase: Phase 3
Study type: Interventional
