Active clinical trials for "Depressive Disorder, Major"

The purpose of this study is to evaluate the efficacy, safety, and tolerability of Levomilnacipran ER versus placebo in the treatment of outpatients with major depressive disorder.

The overall purpose is to determine research based 'next-steps' for outpatients with major depressive disorder who have not had satisfactory outcomes to standard 'first-step' treatments. The primary objective is to compare the acute (up to 12 weeks) treatment effectiveness of augmenting an antidepressant with aripiprazole or with bupropion-slow release (SR) vs. switching treatment to bupropion-SR monotherapy on symptom remission in Veterans with Major Depressive Disorder (MDD) who have not achieved optimal response after an adequate trial on antidepressant (a selective serotonin reuptake inhibitor [SSRI] or serotonin and norepinephrine reuptake inhibitor [SNRI] or mirtazapine) monotherapy. The secondary objectives are to compare the acute (up to 12 weeks) and long term (up to 36 weeks) efficacy, safety, effects on functioning, suicidality, quality of life, anxiety and other associated symptoms, costs and cost-effectiveness of each of the three treatments.

It is challenging for depressed adolescents and their families to access specialized mental health services. A viable option is delivering treatment in the primary care clinic (PCC) setting; however, few effective models are currently available. The overall aim of this study is to assess in the pediatric PCC, the preliminary acceptability and feasibility of a novel collaborative stepped care model of treatment for depressed adolescents.

The purpose of this study is to assess the safety and feasibility of concurrent treatment of nicotine dependence (cigarette smoking) and acute depression. Participants who meet DSM-IV criteria for both nicotine dependence and acute major depression will be given pharmacological treatment for both disorders at the same time, along with a brief behavioral intervention for smoking cessation.

The purpose of this study is to determine the optimal treatment strategy for MDD patients with melancholic features who do not respond to a standard daily dose. This study will allow investigators to mimic standard clinical practice. During the first 2 weeks of treatment, clinical evaluation of individual patient tolerability and efficacy will enable the dose of duloxetine to be adjusted. Patients allocated to the Flex group may have their daily dose of duloxetine adjusted in the attempt to elicit a clinical response.

A multicentre, randomised, open label study of out-patients with major depression who have failed to respond adequately to antidepressant treatment for their current episode of depression. The study compares outcomes associated with two methods of switching from current antidepressant to duloxetine

To evaluate the efficacy of a fixed dose of SR58611A(350 mg q12) compared to placebo in patients with MajorDepressive Disorder (MDD) using escitalopram (10 mgqd) as positive control. The study is a multicenter, US and Canadian, randomized, double-blind, 3-parallel-group, placebo- and escitalopram-controlled, Phase III study consisting of four segments (A, B, C and D). Segment A is a 1-week, placebo, single-blind period. Segment B is an 8-week, double-blind period. Segment C is an optional 18-week double-blind extension period. Segment D is a 1-week safety follow-up period after study drug discontinuation or early termination (during Segment B or C).

The purpose of this study is to evaluate the effects of the addition of CONCERTA® (methylphenidate hydrochloride, a central nervous system (CNS) stimulant) or placebo in adult outpatients with Major Depressive Disorder who are currently being treated with oral antidepressant medication (selective serotonin reuptake inhibitors or selective norepinephine reuptake inhibitors). The general symptoms of depression will be evaluated, as measured by the Montgomery Asberg Depression Rating Score (MADRS) on fatigue, energy, and overall severity of illness. The safety and tolerability of the CONCERTA® and antidepressant combination therapy will also be assessed.

The purpose of this research is to determine if pregnenolone supplement is associated with a reduction in substance use and craving in patients with recurrent major depressive disorder or bipolar disorder and substance abuse/dependence. This research also wants to explore if pregnenolone supplements are associated with improvement in psychiatric symptoms and memory, which are often negatively affected in these patients. It is hypothesized that patients receiving pregnenolone supplements would show greater improvements in mood symptoms and memory, and crave substances less than the patients receiving placebo.

Low heart rate variability is a marker of increased risk of cardiac mortality, and is observed in depressed coronary artery disease patients. Some antidepressants may themselves, however, decrease heart rate variability. We will test the hypothesis that greater reduction in heart rate variability will be associated with duloxetine (which has noradrenergic activity) than escitalopram (a selective serotonin reuptake inhibitor). We will also test the hypothesis that changes in heart rate variability are related to the magnitude of norepinephrine transporter occupancy.
