NCT ID: NCT00108979 Completed - Clinical trials for Major Depressive Disorder

Study of Escitalopram in Adult Patients With Major Depressive Disorder

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

Escitalopram is the S-enantiomer of citalopram. Both escitalopram and citalopram are selective serotonin reuptake inhibitors (SSRIs) and are used to treat depression in adults. This study is designed to evaluate the efficacy, safety, and pharmacoeconomics of escitalopram and an active comparator in patients with major depressive disorder.

NCT ID: NCT00108407 Completed - Clinical trials for Major Depressive Disorder

Study Comparing Two Types of Psychotherapy for Treating Depression and Substance Abuse

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

The purpose of this study is to determine whether Integrated Cognitive Behavioral Therapy or Twelve Step Facilitation Therapy is most effective for treatment of dually diagnosed veterans with depressive and substance use disorders.

NCT ID: NCT00107120 Completed - Clinical trials for Major Depressive Disorder

The Safety and Efficacy of Escitalopram in Pediatric Patients With Major Depressive Disorder

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

Depression affects approximately 2.5% of children and 8% of adolescents. Escitalopram is the S-enantiomer of citalopram. Both escitalopram and citalopram are selective serotonin reuptake inhibitors (SSRIs) and are used to treat depression in adults. This study is designed to provide a systematic evaluation of the safety and efficacy of escitalopram in the treatment of depressed pediatric patients, 12 to 17 years of age. Patients completing the study will be eligible to enter an open-label extension study.

NCT ID: NCT00105989 Completed - Clinical trials for Depressive Disorder, Major

Duloxetine Versus Placebo in the Prevention of Recurrence of Major Depressive Disorder

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

The purpose of this study is to assess the efficacy and safety of duloxetine compared with placebo in the prevention of depressive recurrences among patients with recurrent major depressive disorder.

NCT ID: NCT00105885 Completed - Anxiety Disorders Clinical Trials

Telephone Care as a Substitute for Routine Psychiatric Medication

Telepsych
Start date: November 2003
Phase: N/A
Study type: Interventional

The purpose of this study is to answer the following questions: (1) Does substituting brief, scheduled, clinician-initiated telephone calls (telephone care) for routine psychiatric medication management visits reduce overall healthcare utilization? (2) Is substituting brief, scheduled, clinician-initiated telephone calls (telephone care) for routine psychiatric medication management visits as effective as routine care?

NCT ID: NCT00105820 Completed - PTSD Clinical Trials

Evaluation Study of TIDES Depression Care Quality Improvement Intervention

Start date: June 2003
Phase: N/A
Study type: Interventional

In spite of the impact on veteran�s health status and treatment cost, depression is under-diagnosed and under-treated. The goal of this study is to learn how to implement a previously tested, effective collaborative care model for improving the quality of depression care across multiple Veterans Integrated Service Networks (VISNs). To achieve this goal, we are conducting a randomized controlled trial of evidence-based quality improvement (EBQI), a dissemination method that relies on expert design and local implementation of evidence-based practice interventions. We hypothesize that EBQI will result in increased rates of assessment and appropriate management of depression. Results will be useful in designing realistic chronic care programs and performance measures for continuing care improvement.

NCT ID: NCT00105196 Completed - Clinical trials for Major Depressive Disorder

A Study of Aripiprazole in Patients With Major Depressive Disorder

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

The purpose of this 14 week, randomized, double-blind, placebo controlled study is to assess the safety and efficacy of aripiprazole to placebo as adjunctive treatment to an assigned open-label marketed antidepressant therapy (ADT) in patients with Major Depressive Disorder who demonstrate an incomplete response to a prospective eight week trial of the same assigned open-label marketed antidepressant therapy.

NCT ID: NCT00104611 Completed - Clinical trials for Major Depressive Disorder

Study of a Repetitive Transcranial Magnetic Stimulation (rTMS) Device for the Treatment of Major Depressive Disorder

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

This trial will test the safety and efficacy of a rTMS device for the treatment of major depressive disorder (MDD). It is hypothesized that rTMS will have an antidepressant effect. It is a 10-week, randomized, sham-controlled, multicenter trial in outpatients recruited in both academic and private research centers. It is comprised of three major phases: pre-study screening, acute treatment, and post-treatment taper. Eligible patients will be randomized to one of two rTMS treatment groups. One group will receive active rTMS treatment and one will receive an inactive, or sham, treatment. Each treatment takes about 45 minutes and is done on an outpatient basis. All trial related medical care is provided at no cost to the participant.

NCT ID: NCT00102492 Completed - Clinical trials for Depressive Disorder, Major

Study Of GW679769 In Major Depressive Disorder

Start date: October 2004
Phase: Phase 2
Study type: Interventional

This is a placebo-controlled, fixed dose study that will evaluate the efficacy and safety of GW679769 in subjects with major depressive disorder.

NCT ID: NCT00097175 Completed - Clinical trials for Depressive Disorder, Major

Effects of Tryptophan Depletion on Brain Processing of Emotions in Patients With Mood Disorders

Start date: November 10, 2004
Phase:
Study type: Observational

This study will investigate how the brain process emotions in healthy people and in patients who have major depression in order to better understand the causes of depression. It will examine what happens in the brain when a person responds to words related to different emotions while the brain's ability to manufacture a chemical called serotonin is reduced. Serotonin regulates functions such as emotion, anxiety and sleep, and stress hormones such as cortisol. In this study, participants' serotonin levels are reduced by depleting tryptophan, an amino acid that is the main building block for serotonin. Healthy volunteers and patients with major depression that has been in remission for at least 3 months may be eligible for this study. Candidates must be between 18 and 50 years of age and right-handed. They are interviewed about their medical and psychiatric history, current emotional state and sleep pattern, and family history of psychiatric disorders. Screening also includes psychiatric interviews and rating scales, neuropsychological tests, physical examination, electrocardiogram (EKG), and blood, urine, and saliva tests. Women have their menstrual phase determined by a blood test and home urine ovulation test kit. The study involves two clinic visits in which participants undergo tryptophan depletion and magnetic resonance imaging (MRI). Subjects arrive at the NIH Clinical Center in the morning after fasting overnight. They fill out questionnaires have a blood sample drawn, and then take 74 capsules that contain a mixture of amino acids found in the diet. At one visit they are given capsules that contain a balanced mixture of amino acids one would normally eat in a day; at the other visit, some of the capsules contain lactose instead of tryptophan, causing tryptophan depletion. At 2 p.m. participants fill out the same questionnaires they completed at the beginning of the day and have another blood sample drawn. Then they do a computerized test in the MRI scanner. MRI uses a magnet and radio waves to obtain pictures of the brain. For the test, subjects lie on a narrow bed that slides into the cylindrical MRI scanner. They are asked to press a button in response to words associated with different emotions that appear on a screen. Arterial spin labeling - a test that uses magnetism to measure blood flow in different areas of the brain-is also done during the procedure. After the scan, subjects eat a meal and then return home. DNA from the participants' blood samples is also examined to try to better understand the genetic causes of depression. Some of the white cells from the samples may also be grown in the laboratory so that additional studies can be done later. ...
