Active clinical trials for "Depressive Disorder"

Recently published work has examined the effects of "atypical antipsychotics" in SSRI-treatment resistant patients. In these studies, patients with unipolar depression who were treated with SSRI's, but not responsive to treatment after 4 or more weeks, were supplemented with an atypical. The atypical antipsychotics were found to diminish depression symptoms, as well as benefit sleep quality. We propose a similar study with Quetiapine XR, focusing on thinking processes, mood and anxiety. Patients with depression who are SSRI treatment resistant will be treated with Quetiapine. Cognition will be evaluated in the UBC Mood Disorders Clinic two times: first before Quetiapine addition, then after 8 weeks. Depression symptoms and other measurements will be done at the 9 time points: before Quetiapine, and each week after treatment has begun. The primary purpose of this study is to evaluate the superiority of Quetiapine XR compared to placebo as augmentation therapy in treatment of anxiety and depressive symptoms in SSRI-nonresponsive unipolar patients. Secondarily, we would like to evaluate the safety and tolerability of quetiapine as augmentation therapy in SSRI-nonresponsive unipolar patients.

This study is being conducted to obtain information on the safety and tolerability of repeated doses of GW823296 for 28 days in healthy male and female subjects. In addition, the pharmacokinetics of GW823296 will be evaluated to confirm the doses to be used in Phase II efficacy studies. The effect of repeat dose (RD) of GW823296 on CYP3A4 enzyme activity will be investigated evaluating the pharmacokinetics of midazolam and urine 6-?-hydroxycortisol/cortisol ratio.

The current use of telepsychiatry, or psychiatric care using videoconferencing, is very limited. The present study investigates the use of this method with a depressed Chinese American population in a nursing home. It is believed that this population can benefit from telepsychiatric treatment when used in collaboration with the primary care they receive in the nursing home.

The purpose of this study is to determine whether a home-based intervention matched to stage of change (readiness) for using effective methods to prevent or reduce depression can improve depression outcomes in primary care.

The primary objective of the study is to evaluate whether armodafinil at a target dosage of 200 mg/day is more effective than placebo treatment in improving excessive sleepiness in patients with obstructive sleep apnea/hypopnea syndrome (OSAHS) who have comorbid major depressive disorder or dysthymic disorder.

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.

This study will evaluate the effectiveness of cognitive behavioral therapy (CBT) in treating people with depression and type 2 diabetes.

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.
