Active clinical trials for "Depressive Disorder"

This randomized double-blind placebo-controlled crossover study seeks to evaluate the antidepressant effect of L-leucine, an essential amino acid, in patients with Major Depressive Disorder (MDD).

In this new research study, 80 adults aged > 60 years with a significant depressive disorder and slowed processing and/or gait speed will be randomized to receive levodopa (L-DOPA; which the Candidate has previously shown to increase psychomotor speed and decrease depressive symptoms in older adults), aerobic exercise (itself an effective antidepressant treatment as monotherapy), or their combination in a 2x2 design incorporating placebo and a stretching/toning control. Participants will be evaluated before and after this 12-week duration study across cognitive domains, psychiatric symptoms, gait kinematics and mobility, and task-based magnetic resonance imaging (MRI) focused on effort-based decision making and reward processing. Data from this study will contribute toward the development of improved treatment and prevention strategies to maximize the functioning and active healthspan of older adults with neuropsychiatric disorders.

The main purpose of this study is to assess the efficacy and safety of daily and intermittent dosing of MK-1942 compared to placebo among participants with Treatment-Resistant Depression (TRD) on a stable course of antidepressant therapy. The dual primary hypotheses of the study are that the daily MK-1942 treatment and/or intermittent MK-1942 treatment are superior to placebo in reducing Montgomery-Asberg Depression Rating Scale (MADRS) score.

The purpose of this study is to assess the efficacy of Seltorexant compared with placebo as adjunctive therapy to an antidepressant in improving depressive symptoms in participants with major depressive disorder with insomnia symptoms (MDDIS) who have had an inadequate response to current antidepressant therapy with a selective serotonin reuptake inhibitor (SSRI) or serotonin-norepinephrine reuptake inhibitor (SNRI).

This study aims to evaluate the efficacy of accelerated bilateral repetitive transcranial magnetic stimulation (rTMS) on major depression, anxiety, cognitive function and physiological parameters in elderly depressive patients.

The study evaluates the efficacy and safety of lurasidone compared with placebo in treating Bipolar I Depression.

This study is an optional continuation of previous short-term adult major depressive disorder (MDD) augmentation studies. Patients may only take part in this long-term, open-label research study if they completed a previous double-blind MDD augmentation study using SPD489.

The primary objective of the study is to compare the efficacy of duloxetine 60 mg by mouth daily with placebo in the prevention of depression associated with mild/moderate traumatic brain injury and to enhance cognitive function.

The primary objective will be to pilot the use of escitalopram for the treatment of major depression in patients with epilepsy. The secondary objectives will be to determine effect sizes on scales measuring depressive symptoms, physical symptoms, psychosocial function and quality of life, and to evaluate safety in the population of patients with epilepsy. These results will be used to evaluate the possibility of a future double-blind, placebo controlled RCT of escitalopram for the treatment of major depression in patients with epilepsy.

The purpose of this study is to determine the safety and effectiveness of a nutritional supplement, the probiotic bacteria GanedenBC30. Probiotics are live microorganisms which when taken in large enough amounts are supposed to provide a health benefit. The investigators would like to see whether this supplement can be used as a treatment for Irritable Bowel Syndrome (IBS) and Major Depressive Disorder (MDD). Participants in the study will have both IBS and MDD. In order to find out if GanedenBC30 is effective in treating IBS and MDD, the investigators will compare it to a placebo. About 32 people will take part in this research study. About half of these 32 people will take part at Charles River Medical Associates and half will take part at Burlington Medical Associates. Participants will be recruited from among patients already being seen at Charles River Medical Associates or Burlington Medical Associates for their primary care. The study will last for two months, during which time participants will make eight study visits and will take either Ganeden BC30 or placebo. The investigators hypothesize that subjects treated with the probiotic will have significantly better outcomes with regard to depression and IBS symptoms compared to those who receive placebo.
