Filter by:The objective of the study is to compare the efficacy of intranasal oxytocin versus intranasal placebo to improve depression symptoms in patients with Major Depressive Disorder (MDD) or Dysthymia Disorder.
This protocol, "Repetitive Transcranial Magnetic Stimulation (rTMS) for the Treatment of Major Depressive Disorder (MDD): A Functional Connectivity Magnetic Resonance Imaging (fcMRI) Study," is an open-label pilot treatment study. The purpose of the present protocol is to treat participants with a diagnosis of Major Depressive Disorder with 4 weeks of rTMS, performing fcMRI and EEG studies prior to and following treatment to determine if treatment response is related to changes in fcMRI and/or EEG results. The investigators hypothesize that patients who respond to treatment will display changes in functional connectivity patterns thought to be related to the occurrence of depressive symptoms.
The study will assess safety and tolerability of 0.5 mg/day and 1 mg/day of sublingual (under the tongue) formulation of agomelatine (AGO178) in patients with Major Depressive Disorder over a 52-week open-label phase. Cohort I is restricted to include patients who have completed a previous Novartis agomelatine (178C) Double-blind study. Cohort II will include de-novo patients (those who did not participate in a previous agomelatine 178C study) and will only be open for a limited time span ranging from approximately June to Sept 2010, at which point this cohort II will be closed to enrollment.
This is a 6-week study treatment to evaluate the safety and effectiveness of AZD2066 in patients with major depressive disorder.
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.
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.
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.
The primary objective is to test the hypothesis that quetiapine XR (Extended Release) monotherapy or adjunctive therapy to antidepressant is superior to placebo monotherapy or placebo adjunctive therapy to antidepressant(s) in the acute treatment of depression symptoms in patients with MDD and comorbid GAD. The secondary objectives are to test the hypotheses that quetiapine XR is superior to placebo in the reduction of anxiety symptoms in patients with major depressive disorder and comorbid generalized anxiety disorder, the improvement of the quality of sleep in patients with major depressive disorder and comorbid generalized anxiety disorder and the improvement of the quality of life in patients with major depressive disorder and comorbid generalized anxiety disorder.
The purpose of the study is to evaluate the efficacy, safety and tolerability of three fixed dosages of Lu AA34893 compared to placebo in the treatment of patients with Major Depressive Disorder.
The study investigates the relative efficacy of Interpersonal Psychotherapy and Brief Relational Therapy for Major Depressive Disorder. The primary hypothesis is that there will be no mean difference in efficacy between treatments, but that Brief Relational Therapy will be more efficacious for more self-critical patients and Interpersonal Psychotherapy will be more efficacious for less self-critical patients.
