NCT ID: NCT00205933 Completed - Clinical trials for Major Depressive Disorder

Behavioral Processes Underlying Reward Processing in Depression

Start date: April 2004
Phase: N/A
Study type: Observational

The purpose of this project is to use behavioral techniques to investigate emotional processing in subjects with major depression and healthy comparison subjects.

NCT ID: NCT00204152 Terminated - Clinical trials for Major Depressive Disorder

Treatment for Chronic Depression

Start date: June 2004
Phase: Phase 3
Study type: Interventional

The purpose of this study is to test the clinical efficacy of two psychotherapies for early onset chronic major depression, including Behavioral Activation (Jacobson et al., 2001), and an integrated version of Behavioral Activation and Stress Innoculation Coping (BASIC) for short-term (16 weeks) of individual psychotherapy for adults with chronic major depression. The control condition is an individual workbook condition of Behavioral Activation. These psychotherapies focus on behavior activation, stress reduction and coping strategies to counter depressive symptoms.

NCT ID: NCT00191932 Completed - Clinical trials for Major Depressive Disorder

Switching to Duloxetine From Other Antidepressants

Start date: August 2004
Phase: Phase 4
Study type: Interventional

A multicentre, randomised, open label study of out-patients with major depression who have failed to respond adequately to antidepressant treatment for their current episode of depression. The study compares outcomes associated with two methods of switching from current antidepressant to duloxetine

NCT ID: NCT00191594 Completed - Clinical trials for Major Depressive Disorder

Open-Label Duloxetine Extension Phase in Patients Who Have Completed Previous Duloxetine Trials

Start date: March 2005
Phase: Phase 3
Study type: Interventional

A study in patients with depression

NCT ID: NCT00188942 Completed - Clinical trials for Major Depressive Disorder

A Neuroimaging Investigation of Brain Activity in Major Depressive Disorder and Bipolar Disorder

Start date: February 2005
Phase: Phase 4
Study type: Interventional

This study employs functional magnetic resonance imaging to compare brain activation patterns during a depressive episode in patients diagnosed with bipolar disorder, major depressive disorder, and a group of healthy control subjects. Depressed patients will be treated with a combination of fluoxetine and olanzapine and undergo MRI scans before, during, and after pharmacotherapy.

NCT ID: NCT00188396 Completed - Depression Clinical Trials

Effect of the Menstrual Cycle on the Symptoms of Depression and Treatment Response

Start date: April 2004
Phase: N/A
Study type: Interventional

Objectives: This prospective investigation will compare premenopausal, perimenopausal and postmenopausal women's response to antidepressant medication. The effects of the menstrual cycle on the symptoms of depression and antidepressant response will also be examined. Hypotheses: Premenopausal women will show a significantly better response to a selective serotonin reuptake inhibitor (SSRI) than peri- or postmenopausal women. Premenopausal women during lower estrogen phases of the menstrual cycle will complain of increased depressive symptoms despite treatment. Perimenopausal and postmenopausal women with irregular periods and generally low estrogen levels will show less symptom variability over time. Method Subjects: Eighty-four women (28 premenopausal, 28 perimenopausal, 28 postmenopausal) meeting Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) criteria for major depressive disorder will be enrolled in the study. Procedure: All the subjects will be followed prospectively for 12 weeks and through 2 menstrual cycles while receiving treatment with a standard SSRI antidepressant agent. All eligible women will have a structured clinical interview and will complete questionnaires assessing their depressive symptoms. Blood samples will be collected to evaluate for reproductive hormone levels during the late follicular, midluteal and late luteal phases of the menstrual cycle for two consecutive cycles. Serum SSRI levels will also be collected at these times. As the women in the perimenopausal and postmenopausal groups either have irregular menstrual cycles or no longer cycle, they will have blood samples drawn at baseline and on 6 other occasions. Research Implications: As the majority of psychiatric medication is prescribed to women, understanding the interplay between the menstrual cycle and antidepressant medication will ultimately translate into more diverse and improved patient care. The proposed study is one within a developing research program, which will in part be further guided by this study.

NCT ID: NCT00186446 Active, not recruiting - Clinical trials for Major Depressive Disorder

Treatment of Nicotine Dependence and Acute Depression

Start date: June 2004
Phase: Phase 4
Study type: Interventional

The purpose of this study is to assess the safety and feasibility of concurrent treatment of nicotine dependence (cigarette smoking) and acute depression. Participants who meet DSM-IV criteria for both nicotine dependence and acute major depression will be given pharmacological treatment for both disorders at the same time, along with a brief behavioral intervention for smoking cessation.

NCT ID: NCT00186056 Active, not recruiting - Depression Clinical Trials

Mifepristone in Refractory Depression

Start date: January 2003
Phase: Phase 3
Study type: Interventional

The purpose of the study is to examine the effectiveness of mifepristone treatment in patients with refractory depression. Refractory depression is defined as clinical depression that is unimproved after treatment with at least 2 different antidepressants of adequate dose and time trial. Mifepristone will augment current medications.

NCT ID: NCT00182533 Terminated - Clinical trials for Major Depressive Disorder

Sertraline in Generalized Social Phobia With Co-Occurring Anxiety and Mood Disorders

Start date: July 2002
Phase: Phase 4
Study type: Interventional

Selective serotonin reuptake inhibitors (SSRIs) including sertraline have been found to be effective in the treatment of generalized social phobia (GSP). However, virtually all of the current treatment studies with medicines, including the SSRIs, have excluded patients with social phobia who have other co-occurring conditions. In fact, 80% of individuals suffering with primary social phobia have at least one other anxiety. This study will evaluate the safety and efficacy of sertraline in the treatment of generalized social phobia with co-occurring anxiety and mood disorders.

NCT ID: NCT00179283 Completed - Clinical trials for Major Depressive Disorder

Sertraline vs. Venlafaxine XR

Start date: April 2002
Phase: Phase 3
Study type: Interventional

This is a randomized, double-blind, active control, 8-week, flexible dose study of sertraline vs. venlafaxine Extended Release in the acute treatment of Major Depression in male and female outpatient sites that will recruit 15-20 patients each. Subjects will be randomized in a 1:1 ratio to receive either sertraline or venlafaxine XR based on a computer-generated randomized list.
