Active clinical trials for "Depressive Disorder"

The purpose of this study is to see if creatine, which is a naturally occurring chemical in the body, is effective for treating Major Depressive Disorder (MDD) in female teenagers. Creatine may have effects of interest in the brain. The reason for the MRI component of this study is to learn about new ways to see inside the brain. The investigators will use magnetic fields and radio waves to look at the brain and chemicals in the brain. The investigators hope that this technique will have medial use in the future. The primary hypothesis of the study is that oral creatine supplementation will have a beneficial effect as adjunctive therapy in female adolescents with MDD who are non-responders to an adequate trial of the SSRIs Fluoxetine or Escitalopram.

This study is intended to evaluate the efficacy and safety of lamotrigine as an antidepressant augmentation agent in a sample of individuals with major depression and a history of both prior non-response and prospective failure to respond to at least one adequate trial of an antidepressant (for a total of two failed trials).

This study is designed to assess the use of pramipexole dihydrochloride and quetiapine (Seroquel) XR as combination therapy for bipolar depression. The proposed benefit of the combination therapy investigated in this study is improved treatment of bipolar depression.

The primary purpose is to study the efficacy, safety, and tolerability of LY2216684 as an adjunctive treatment for 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) (as defined by history).

This study will design and test a cognitive behavioral therapy for depressed adolescents that uses family interactions to help with treatment.

The purpose of this study is to determine if an eight-week intervention with omega-3 fatty acids significantly reduces depressive symptoms in symptomatic peri- and postmenopausal women. We hypothesize that an eight-week trial with omega-3 fatty acids promotes significant improvement in depression symptoms in peri- and postmenopausal women.

This study will examine whether measures of brain electrical signals taken after a week of antidepressant medication treatment can predict whether a full treatment regimen will be effective.

The primary aims of this study are to: Assess the efficacy of aripiprazole augmentation for the acute and continuation treatment of TRLLD. Hypothesis 1: Patients with TRLLD (defined as those who do not remit after 12 weeks of acute treatment with venlafaxine XR) will have a higher rate of remission with aripiprazole than with placebo augmentation (primary outcome) and greater improvement in depressive symptoms and stability of remission (secondary outcomes). Assess the tolerability of aripiprazole in TRLLD with a focus on adiposity and akathisia/restlessness. Hypothesis 2: Aripiprazole will be associated with a higher rate of clinically significant akathisia and increased adiposity than placebo. The Secondary/exploratory aims of this study are to: Examine anxiety, medical burden, and executive impairment as moderators of aripiprazole augmentation efficacy in TRLLD. Hypothesis 3: Pre-levels of anxiety symptoms, medical burden, and executive impairment will be treatment-specific factors: they will moderate the efficacy of aripiprazole augmentation. The aripiprazole-placebo difference will be greater in individuals with these variables, compared to those without these variables because these three factors will be associated with a decreased likelihood that "staying the course" with venlafaxine monotherapy will achieve remission. Examine genetic predictors (phase 1) and moderators (phase 2-3) of treatment outcomes, while controlling for drug exposure. Hypothesis 4: Selected polymorphisms will reduce remission rate with venlafaxine and will reduce efficacy and tolerability with aripiprazole.

Depression is one of the most common mental health problems, with at least one in six adults suffering from this at some time in their life. It can become long-lasting and frequently recurs. Depression has a large negative impact on quality of life of patients and their carers and it has also been shown to be one of the leading causes of working age adults receiving disability payments in the UK. The need for improved treatment has been recognised by the Department of Health and others. Improvements in drug treatments are therefore required. There has been recent increased understanding of some of the causes of the frequent lack of complete response seen with antidepressants. The stress hormone, cortisol, is often elevated or poorly controlled in depression and there is laboratory and clinical research to show that this hormonal change reduces the benefits from antidepressants with associated poor outcome and memory problems. Recently it has been shown in small studies that giving treatments that reduce cortisol or block its harmful effects for between 1 and 3 weeks overcome these negative consequences. Our group is particularly interested and experienced in this topic. The investigators plan to study a drug that decreases cortisol levels in people who have not recovered with standard antidepressants so that the investigators can find out the usefulness of this treatment (compared with placebo (dummy tablet)) in day to day life as well as checking closely for side-effects (the initial studies have shown that the particular drug the investigators wish to study (metyrapone) has few side effects). The investigators will also measure cortisol and see if its level can tell us which people do best with this treatment. The investigators will carry out this study in 3 centres across the UK. The investigators will carry out some additional tests of specific sorts of memory and decision making and also do this while scanning the brain (in a painless test). The results of these tests, along with tests of brain wave patterns, should help us understand more fully how this new treatment is working and who responds best to it. The study will help us find out if this drug should be used more widely for people not responding to standard treatments and will also lead on to the development of other new treatments with an anti-cortisol effect to help tackle the major problem of poor outcome from depression.

Study F1J-US-HMFS comprises two identical multicenter, 9-month, randomized, placebo-controlled, double-blind, trials (HMFSa and HMFSb). The purpose of this study is to compare the efficacy and safety of Duloxetine 60 milligrams (mg) once daily to placebo on depression in patients aged 18-65. Data from the two trials will be reported in both individual and pooled analyses. Pooling the two studies will allow for increased power to detect differences between duloxetine and placebo on secondary and exploratory objectives. Only one data lock is planned for this study, when all patients have completed all study procedures.
