Active clinical trials for "Depressive Disorder, Major"

The purpose of this study is to assess the dose-response relationship of 2 doses of JNJ-42847922 before interim analysis, and potentially 3 doses based on interim analysis results, compared to placebo as adjunctive therapy to an antidepressant drug in improving depressive symptoms in participants with Major Depressive Disorder (MDD) who have had an inadequate response to current antidepressant therapy with a selective serotonin reuptake inhibitor (SSRI) or serotonin-norepinephrine reuptake inhibitor (SNRI); and to assess the safety and tolerability of JNJ-42847922 compared to placebo as adjunctive therapy to an antidepressant in participants with MDD.

In essence the researchers are hoping to test two separate hypotheses (described below in the form of research questions). Therefore, the proposed analysis has been outlined according to each hypothesis. Hypothesis 1: Is low-dose quetiapine (50 mg/day) more effective for patients with depression who have insomnia at treatment baseline? (Stated differently: is low-dose quetiapine 50 mg/day effective as monotherapy for patients with depression regardless of whether or not they have insomnia at baseline?). Hypothesis 2: Is high-dose quetiapine (150 - 300 mg/day) more effective for patients presenting with melancholic depression at treatment baseline?

The purpose of this study is to evaluate the efficacy and safety of AGN-241751 in participants with Major Depressive Disorder

The primary purpose of this study is to evaluate the effect of a single 84-milligram (mg) dose of intranasal esketamine compared to placebo, on next day driving performance and repeated administration of 84 mg intranasal esketamine on same-day driving performance as assessed by the mean difference of standard deviation of lateral position (SDLP) from an on-road driving test.

The aim of this study protocol is to conduct a confirmatory efficacy trial to test whether the Memory Support Intervention improves illness course and functional outcomes in major depressive disorder (MDD) and cognitive therapy (CT).

The present study explored the effects of the implementation of the Pythagorean Self Awarenes Intervention (PSAI) on patients diagnosed with major depressive disorder. The primary aim was to evaluate the effectiveness of PSAI compared to the usual care provided for adults with major depressive disorder with respect to the reduction of depressive symptoms. Secondary aims of this study included reduction of stress and anxiety, enhancement of healthy lifestyle and improvement of affect, sleep quality and cognitive functions of patients.

This study aims to investigate the effects of the Switch intervention on motivation and associated processes and explore the dynamics between the processes. A single case approach is followed, with a pre-post and follow-up assessment design, and continuous ambulatory assessments (experience sampling method (ESM) and step count).

This study evaluates the effectiveness of vortioxetine on depressive symptoms in patients with depression and early dementia

This is a Phase 2 clinical study evaluating the safety and effectiveness of SP-624 as compared to placebo in the treatment of adults with Major Depressive Disorder.

The non-invasive type ultrasonography system is applied to patients with major depressive disorder to evaluate their effectiveness and safety. Brain Computer Tomography(CT) and Magnetic Resonance Image(MRI) are taken to induce images before transcranial low intensity focused ultrasonic stimulation. Through random extraction, the group is divided into treatment group and placebo group. The treatment is started by targeting left Dorsolateral prefrontal cortex(DLPFC) region according to assigned groups. As for women, considering mood change during menstrual cycle, the treatment is taken place 1 week after the menstruation has initiated. The treatment group and the placebo group will be treated three times a week for two weeks. To evaluate clinical symptoms, Quick Inventory of Depressive Symptomatology-Self Report, Scale for Suicidal Ideation, state-trait anxiety scale, frontal lobe management function test, memory test, and continuous performance test are performed before, during, and after treatment. For the assessment of side effects, Systematic Asseseement for Treatment Emergent Events-General Inquiry(SAFTEE) are conducted for treatment presentation events every week during the treatment implementation period and every two weeks after the treatment is completed.
