Filter by: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 demonstrate the efficacy of agomelatine (AGO178) 25 mg and 50 mg in the prevention of relapse in patients with Major Depressive Disorder (MDD). Eligible patients will undergo open-label treatment for 20 to 26 weeks, depending on response to treatment. Patients demonstrating stable response at the end of the open-label treatment phase will be assigned to receive agomelatine or placebo for 52 weeks.
The purpose of this study is to learn how to help veterans play a stronger role in shaping their mental health care. Specifically we want to see if we can help veterans improve their mental health treatment by helping them decide if they want to involve family in their mental health treatment, and if so, how. The study will compare a "family member provider" program to an "enhanced treatment as usual approach" in achieving these goals.
Major depression is increasingly recognized to be a chronic and highly recurrent condition, which results in significantly increased health problems. One possible mechanism that may contribute to treatment resistance is increased production and release of chemicals called proinflammatory cytokines in patients with major depression. These chemicals mediate the body's response to infectious agents like bacteria and have been shown to be increased by psychological stress. They produce the symptoms that we associate with being sick, including fever, malaise and changes in sleep and appetite. Several lines of evidence indicate that proinflammatory cytokines may contribute to the development of major depression and may thus represent a novel target for the pharmacological treatment of the disorder. The TNF-alpha antagonist, Infliximab (Remicade®), is an infusion style drug approved by the FDA for the treatment of inflammatory conditions like Crohns disease and rheumatoid arthritis. The researchers are conducting a study to see if the infliximab (Remicade®) is more effective than placebo in acutely reducing symptoms of depression in patients who have elevated proinflammatory markers and have not responded to, or been unable to tolerate, at least two previous treatments in the current depressive episode. Proinflammatory markers are measured by a simple blood test for C-Reactive Protein (CRP) levels in the body. After appropriate screening to determine eligibility, 64 subjects with treatment resistant depression will be randomized to receive three infusions of either infliximab (Remicade®) or placebo (salt water) in the Emory Infliximab Infusion Center in the Division of Digestive Diseases, Emory University School of Medicine. Subjects will be followed for 12 weeks with evaluations at weeks 0 (baseline), 1, 2, 3, 4, 6, 8, 10 and 12. The first infliximab (Remicade®) infusion will occur at the first (Baseline) visit. The second infusion will occur at Study Week 2 (the third visit). The third infusion will occur at Study Week 6 (Visit 6). The choice of three infusions, and the infusion schedule, is based on current recommendations for the use of infliximab (Remicade®) in conditions for which it has received FDA approval. Subjects will be evaluated for twelve weeks by trained clinicians for changes in depression symptoms and improvements in quality of life. In addition, a physician will evaluate subjects each visit to make sure they are remaining healthy. Blood will be drawn at baseline prior to infusion and all subsequent visits to check labs for safety but also to evaluate potential relationships between changes in inflammatory activity and therapeutic response. After Study Week 12, participants will be monitored by phone, every 4 weeks during the 22-Week Post Study Follow-up Phase to assess physical and psychiatric symptoms in the period following the final infusion. At the baseline and Week 8 visits, subjects will be admitted to the Atlanta Clinical Translational Science Institute (ACTSI), a research unit in the Emory Hospital, for an extended evaluation. The purpose of coming to the ACTSI will be for researchers to evaluate whether treatment with infliximab improves endocrine function, inflammation, sleep and thinking abilities in people who are depressed. For all other visits (Week 1, 2, 4, 6, 10 and 12), participants will come for an office visit in the Winship Cancer Institute.
This study will evaluate the efficacy, safety and tolerability of agomelatine 25 mg or 50 mg per day and will compare agomelatine and paroxetine tolerability. Eligible patients will receive double-blind study medication for 8 weeks. One week after completion of the double-blind treatment phase there will be a single follow-up visit.
In this study, the focus is on an individual's attachment security and its relation to treatment outcome in Major Depression.Adult attachment reflects how one seeks psychological and physical proximity to others for security and protection in times of stress. Researchers typically define four types of attachment security: one secure and three insecure (preoccupied, dismissing, and fearful). Adults with Major Depressive Disorder (MDD) will be randomly assigned to either Interpersonal Psychotherapy (IPT) or to Cognitive Behavior Therapy (CBT). The expectation is that adults with avoidant attachment styles will respond better to CBT, and adults with preoccupied attachment styles will respond better to IPT. Also, in comparison to CBT, outcome in IPT is hypothesized to be more closely related to change in attachment.
Evaluation of the novel deep TMS H-Coil design as an augmentation measure in the treatment of medication resistant major depression. Stimulation is administered with and without cognitive-emotional provocation.
This study compares the efficacy of risperidone to that of paroxetine in the treatment of panic attacks in patients with Panic Disorder and with Major Depressive Disorder with Panic attacks and compares the side effect profile of risperidone vs. paroxetine in treatment of panic attacks and compares response rates of risperidone vs. paroxetine in treatment of panic attacks.

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