Active clinical trials for "Depressive Disorder, Major"

Since antidepressants and antipsychotics have common receptorial mechanisms of action (H1 antagonism, 5HT2 antagonism), the impact of antidepressants in terms of metabolic syndromes is a matter of concern. The main objective of this study is to assess the differential impact of antidepressants in terms of weight gain and metabolic syndromes.

In this pilot study, the PI proposes to include 20 African American participants with Fibromyalgia to explore the effect of r TMS on pain and depressive symptoms.

As of May 21st, 2012, the purpose of this study is to test the antidepressant effect of ketamine when given repeatedly over a period of 1 week, as well as the use of Lithium as a relapse-prevention strategy for patients with treatment-resistant depression (TRD) who respond to an initial series of ketamine infusions. Ketamine is a Food and Drug Administration approved anesthetic (a drug used to produce loss of consciousness before and during surgery). Ketamine is not approved for the treatment of major depressive disorder and is considered experimental in this study.

Purpose : This study will determine whether MK-0657, a selective NR2B Antagonist, can quickly improve symptoms of depressed mood, psychomotor retardation, poor motivation and reduced enjoyment of things in patients with major depression. MK-0657 decreases the activity of a brain receptor called NMDA, which the chemical glutamate binds to, possibly inducing a rapid antidepressant response. People between 18 and 55 years of age who have major depression of at least 4 weeks' duration and have not been helped by two antidepressants approved for major depression may be eligible for this study. Women who are able to have children are excluded. Participants are admitted to the NIH Clinical Center for two study phases, as follows. Phase I (1 to 2 weeks): Patients are tapered off their current medications. Phase II (7 weeks): Patients are randomly assigned to take either MK-0657 or placebo (look-alike capsules with no active ingredient) by mouth for 12 days. At some point during the second part this phase, patients who had been taking MK-0657 are switched over to placebo and those who had been taking placebo are switched to MK-0657. Participants undergo the following procedures during the study:Physical examination twice (at the beginning and at the end of the study) Electrocardiogram (ECG) four times Blood tests about six times Rating scales up to 28 times to assess the effects of MK-0657 on mood and thinking Blood pressure measurements three times a day. Study examines the effectiveness of a new medication, targeting a system called glutamate, will improve depression when compared with placebo.

This study will assess the safety, tolerability and efficacy of desvenlafaxine succinate sustained release (DVS SR) in subjects with major depressive disorder.

This open-label study will assess the medication Geodon® (Ziprasidone) in pediatric patients, aged 13-17, diagnosed with psychotic disorder. Eligible adolescents will receive Geodon® for 7 weeks and stay at the NYSPI Children's Day Unit (CDU) during the day. If clinically appropriate, they may also stay at the New York State Psychiatric Institute (NYSPI) Schizophrenia Research Unit (SRU) inpatient facility.

Desvenlafaxine succinate (DVS) is a potent and selective serotonin and norepinephrine reuptake inhibitor (SNRI). This study will investigate the safety, efficacy, and tolerability of DVS SR versus escitalopram in women with major depressive disorder (MDD) who are postmenopausal.

To evaluate the antidepressant effect of adjunctive treatment with Eszopiclone in subjects receiving venlafaxine for the treatment of Major Depressive Disorder (MDD).

To evaluate the long-term safety of desvenlafaxine sustained release (DVS-233SR) during open-label treatment of outpatients with major depressive disorder (MDD).

The purpose of this study is to evaluate the efficacy, safety, and tolerability of vilazodone relative to placebo in adolescent outpatients (12-17) with major depressive disorder.
