Active clinical trials for "Depressive Disorder, Major"

To assess the long-term safety and tolerability of oral OPC-34712 (brexpiprazole), given in addition to an FDA approved antidepressant (ADT) for the treatment of adults with Major Depressive Disorder (MDD)

This study will evaluate the safety and effectiveness of fluoxetine flexible dosing in the treatment of MDD in adult Japanese participants. Participants who complete the short-term treatment phase of Study B1Y-JE-HCLV (NCT#: NCT01808612) will be allowed to enroll in this study, and receive fluoxetine treatment for an additional 52 weeks.

The goal of the study is to examine how cognitive behavioral therapy (CBT), a common treatment for adolescent depression, affects brain functioning. Depressed adolescents will complete an initial assessment consisting of an interview, questionnaires, computer tasks, and an EEG recording. EEG (electroencephalography) measures brain activity by recording the electrical activity along the scalp caused by the firing of neurons within the brain. They will then complete 12 sessions of cognitive behavioral therapy, which will be 50 minutes long and held once a week for 12 weeks. Before their third therapy session, participants will complete a computer task while EEG data are recorded. After completing the treatment, the participants will complete a final assessment, which will include questionnaires, computer tasks, and an EEG recording. They will also complete follow-up assessments over the phone 1, 3, and 6 months after completing the treatment. This study will also include healthy control participants. They will complete an initial assessment consisting of an interview, questionnaires, computer tasks, and an EEG recording. Three weeks later, they will return to complete a behavioral task while EEG data are recorded. Twelve weeks after the initial assessment, they will complete a final assessment, which will include questionnaires, computer tasks, and an EEG recording.

In this study, quetiapine XR or placebo will be administered orally for 6 weeks to major depressive disorder patients with lack of response to existing antidepressants, with the aim of evaluating the efficacy of quetiapine XR and dose-response in three quetiapine XR dose groups based on changes in Montgomery-Asberg Depression Rating Scale (MADRS) scores.

This study will determine the efficacy, safety, and tolerability of a 40 milligrams (mg) once-daily (QD) dose of LY2940094 for 8 weeks in participants with MDD.

Anxiety, Depression and Somatoform disorders are highly prevalent in primary care. Very often these conditions remain undiscovered and/or untreated. In order to ease this urgent health care problem in the future, the investigators conduct a cluster-randomized controlled trial, implementing a tandem working cooperation between a nurse practitioner (Counseling Assistant - CA) and a general practitioner (GP) on-site its own practise. The CA's task is to enhance the patients abilities to engage in a better self-management of their psychological symptoms and complaints, to enhance self-efficacy and empower the patients to tackle problems of daily living.

To compare the efficacy of brexpiprazole (flexible dose) with placebo as adjunctive therapy to an assigned open label antidepressant therapy (ADT) in the proposed subject population with MDD.

Primary Objective: - To evaluate the effects of two fixed doses of SSR149415 (250 mg bid and 100 mg bid) on hypothalamic-pituitary-adrenal axis function in patients with major depressive disorder. Secondary Objectives: To evaluate the tolerability and safety of SSR149415 in patients with major depressive disorder. To evaluate the efficacy of two fixed doses of SSR149415 compared to placebo in patients with major depressive disorder. To evaluate plasma concentrations of SSR149415.

The purpose of this study is to examine the effects of vilazodone for the treatment of depression in older adults.

Study to assess efficacy of Duloxetine 120 mg and Duloxetine 60 mg in patients hospitalized for severe depression after 4 weeks of treatment. To evaluate the rescue option in non-responding patients. Safety of Duloxetine will also be assessed.
