Active clinical trials for "Depressive Disorder, Major"

The primary objective is to compare the antidepressant efficacy, safety, and tolerability of DVS SR versus placebo in subjects with Major Depressive Disorder. Additional objectives include testing both general and functional quality-of-life outcomes and satisfaction with therapy reported by the subject.

The objective is to evaluate the efficacy and safety of two doses of SSR149415 (250 mg and 100 mg twice daily) compared to placebo and escitalopram 10 mg once daily in outpatients with major depressive disorder.

This study is to verify the efficacy of fluvoxamine maleate given for 8 weeks in the treatment of children and adolescents with depression or depressive state

This study examines the difference in the effectiveness of two natural compounds, eicosapentanoic (EPA) and docosahexanoic (DHA)omega-3 fatty acids, in treating major depressive disorder. Both types of omega-3 fatty acids are commonly found in fish oils. It is believed that a deficiency in these omega-3 fatty acids may lead to the development of major depression.

To evaluate the efficacy of two fixed doses of SR58611A (175 mg q12 and 350 mg q12) compared to placebo in patients with Major Depressive Disorder (MDD) using paroxetine (20 mg qd) as positive control. In addition, the tolerability and safety of SR58611A in patients with MDD will be evaluated.

This is an 8 week study for patients who are currently taking antidepressant medication but not fully responding. Ropinirole CR would be taken in conjunction with current antidepressant medication. Patients come into the clinic once a week when starting on the medication and then once every other week for the remainder of the 8 weeks.

The primary purpose of this protocol is to compare PDE4 levels before and after starting a selective serotonin reuptake inhibitor (SSRI) sertraline, citalopram or escitalopram in unmedicated depressed patients. The secondary purpose is to compare PDE4 levels between unmedicated depressed patients and healthy subjects.

The purpose of this study is to study the effect of duloxetine treatment on (1) cognitive functions, the brain mechanisms involved with thinking, reasoning, learning, and remembering; (2) psychosocial functions, how someone interacts with his/her social environment; and (3) the relationship between these two functions, in people who have major depressive disorder, a severe form of depression.

The purpose of this study is to examine the effects of neurocognitive enhancement on cognitive abilities and related social and adaptive behaviours in individuals diagnosed with major depressive disorder. Subjects in this study will be randomized to receive Neurocognitive Enhancement Therapy (NET) or to a wait list and then NET . Secondary aims include examining whether the cognitive benefits are potentiated by repeated exposure during in-home practice with complementary exercises. Additionally, the investigators will examine the durability of the effects and their generalization to functional capacity and everyday functional performance after completion of the groups.

The purpose of this study is to test if GSK163090 can reduce the symptoms of depression. The safety and how well the body can handle the drug will also be investigated. The study will be conducted in Russia in hospitalised patients with severe depression. GSK163090 will be compared with placebo, which looks like the study drug but does not contain any active substance. Subjects will be given either the study drug or the matching placebo.
