Active clinical trials for "Depressive Disorder, Major"

The purpose of this research study is to determine the effectiveness of 2 target doses of R228060 in comparison with placebo during 6 weeks of treatment in moderately to severely depressed adult subjects with major depressive disorder. Approximately 488 subjects will be involved in the study.

Primary Objective: To compare the efficacy and safety of DVS-233 SR versus placebo treatment in reducing the relapse rate of depressive symptoms in subjects with major depressive disorder (MDD), and to compare the percentages of relapse in terms of time to relapse between DVS-233 SR and placebo treatment groups by using survival analysis. Secondary Objective: To assess the response of subjects on DVS-233 SR versus placebo for the clinical global evaluation, functionality, general well-being, pain, and absence of symptoms (Hamilton Psychiatric Rating Scale for Depression, 17-item [HAM-D17] < 7).

Our goal is to study pharmacogenetics in Mexican-Americans, using depression treatments as a proof of the concept that pharmacogenetic approaches can be used to optimize treatment strategies for common and complex disorders in this population.

Primary: To compare the antidepressant efficacy and safety of subjects receiving DVS-233 SR versus subjects receiving placebo. Secondary: To assess the response of subjects receiving DVS-233 SR for the clinical global evaluation, functionality, general well-being, pain, and remission (Hamilton Psychiatric Rating Scale for Depression, 17-item [HAM-D₁₇] < 7) versus those subjects receiving placebo.

A study of the safety and efficacy of duloxetine in elderly patients (greater than 65 years old) with major depressive disorder

The purpose of this study is to evaluate the antidepressant effectiveness of Geodon for the treatment of patients diagnosed with Bipolar II disorder who are currently experiencing a major depressive episode.

The purpose of the study is to try to see if antidepressant medications cause changes in QEEG measurements in the brain. QEEG is a mathematical analysis of electrical currents in the brain using electrodes placed on the scalp. Previous studies have shown that mood improvement (clinical response) caused by antidepressant medications was preceded by changes in QEEG measurements in the brain.

Corlux (mifepristone) is a new medication that modulates the body's use of a hormone called cortisol. Under normal conditions, cortisol and other hormones are created by the body in response to physical and emotional stress, triggering a healthy stress response. People who suffer from psychotic major depression may have unusually high levels of cortisol circulating within them or abnormal patterns of cortisol levels, overloading the stress response mechanism and causing symptoms of psychosis such as delusional thoughts or hallucinations. If Corlux can keep the body's cortisol receptors from being overloaded, the stress response system may return to normal function, which may result in improvement of symptoms. The purpose of this 56 day study is to learn the safety and effectiveness of Corlux in patients who have been diagnosed with psychotic major depression (PMD).
