NCT ID: NCT00330434 Withdrawn - Depression Clinical Trials

Effect of Ethanol and Genetic Polymorphisms on Bupropion Metabolism

Start date: December 2005
Phase: N/A
Study type: Interventional

The two purposes of this study are 1. to determine what effect the chronic and moderate/heavy drinking of alcoholic beverages has 1. on the blood level of bupropion and chlorzoxazone and their major breakdown products in the blood and 2. on the stimulant effect of bupropion and 2. to determine what effect a normal and common (25% frequency) genetic variation of a specific liver enzyme (that breaks down bupropion) has 1. on the blood levels of bupropion and its major breakdown products in the blood and 2. on the stimulant effect of bupropion. Two groups of volunteers will be recruited for this study: 1. volunteers who drink moderate to heavy amounts of alcohol frequently and 2. volunteers who usually do not drink alcohol. Volunteers will NOT be asked to change their drinking (or nondrinking) habits during the study.

NCT ID: NCT00327756 Withdrawn - Depression Clinical Trials

Mitochondrial Dysfunction in the Pathophysiology and Treatment of Bipolar Disorder

Start date: May 2006
Phase: Phase 2
Study type: Interventional

This study will examine whether mitochondrial function is impaired in patients with bipolar disorder. Mitrochondria are small organelles inside the cell that are responsible for energy production. Recent studies in animals and humans suggest that abnormalities of mitrochondria may be involved in bipolar depression. The study will also examine whether the food supplement Coenzyme Q10 (CoQ10) improves mitochondrial function and symptoms such as depressed mood, low energy, anxiety or slowness in thinking and movements in bipolar patients. CoQ10 has been used to increase cell energy production and as an antioxidant. It has had some benefit in patients with Parkinson's disease and migraine and in prolonging survival in patients with cancer and heart failure. Patients 18-65 years of age with bipolar disorder who are currently in a depressive episode of at least 4 weeks duration may be eligible for this study. The study has four phases, as follows: Phase I: Medication Withdrawal Patients taper off all psychotropic medications, usually over 1 to 2 weeks. Phase II: Baseline Evaluation After being off all medication for about 2 weeks, patients undergo the following procedures: - Magnetic resonance imaging (MRI) and magnetic resonance spectroscopy (MRS). The two procedures are performed in an MRI scanner. Both tests use a strong magnetic field and radio waves to obtain images that provide information on brain anatomy and chemistry. - Blood tests to assess mitochondrial function isolated from blood cells. - Skin biopsy for tests of mitochondria. A small sample of skin tissue 5 x 5 millimeters is surgically removed. Phase III: Administration of CoQ10 or Placebo Participants are randomly assigned to take either CoQ10 or placebo (an inactive look-alike substance) twice a day by mouth. While taking the study medication, patients have the following procedures periodically: - Rating scales for anxiety and depression and adverse events. - Check of vital signs. - Blood and urine sample collections. Phase IV: Study Completion At the end of the 8 weeks of treatment, patients have a physical examination and electrocardiogram, and the procedures in phase II are repeated. Participants may then receive short-term treatment (up to 12 weeks) with medications for bipolar depression, followed by referred to a community physician for long-term treatment.

NCT ID: NCT00317018 Withdrawn - Depression Clinical Trials

Implementing Telemedicine-Based Collaborative Care for MDD in Contract CBOCs

Start date: May 2008
Phase: N/A
Study type: Interventional

Small contract VA Community Based Outpatient Clinics present unique challenges to implementation of collaborative care because of their distinct organizational characteristics and lack of on-site psychiatrists. A recent effectiveness study, successfully used telemedicine technologies to adapt the collaborative care model for small rural VA Community Based Outpatient Clinics. The purpose of the proposed study is to implement this telemedicine-based collaborative care model in small Contract VA Community Based Outpatient Clinics and determine its sustainability and cost-effectiveness.

NCT ID: NCT00294944 Withdrawn - Clinical trials for Major Depressive Disorder

The Effectiveness of Idazoxan in Treating TRD

Start date: n/a
Phase: Phase 3
Study type: Interventional

Assessing the effectiveness of Idazoxan as a treatment for depressive patients who did not respond to treatment with SSRI

NCT ID: NCT00276978 Withdrawn - Clinical trials for Therapy-resistant Depression

Aripiprazole Augmentation Therapy in Treatment-resistant Depression

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

20 therapy-refractory patients with major depression will be treated for 3 weeks with Aripiprazole 10 mg/d. Effectivity will be assessed using a pre-post comparison of different psychopathological rating scales and patient adherence.

NCT ID: NCT00273624 Withdrawn - Clinical trials for Therapy-resistant Depression

Olanzapine Augmentation Therapy in Treatment-resistant Depression: a Double-blind Placebo-controlled Trial

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

60 patients with major depression will be treated with 10 mg Olanzapine or Placebo for 2 weeks. In case of response (reduction of depressive symptoms)the study will be continued for further 60 days.

NCT ID: NCT00262665 Withdrawn - Clinical trials for Major Depressive Disorder

Randomized, Placebo-controlled Trial of an AMPAkine in Major Depressive Disorder

Start date: March 2005
Phase: Phase 2
Study type: Interventional

The purpose of this study is to test a candidate drug, Org 24448,in a phase II clinical trial in adult patients with moderately treatment-resistant unipolar major depressive disorder.

NCT ID: NCT00227292 Withdrawn - Depression Clinical Trials

Cipralex in Treatment of Depressive Symptoms and Chronic Back Pain

Start date: November 2007
Phase: Phase 4
Study type: Interventional

Chronic low back pain (CLBP) is one of the most frequent forms of chronic pain and can result in significant functional impairment. This is often associated with major depression too. Previous research reported significant beneficial effects of antidepressant medication in alleviating depression and pain intensity. The aim of this study is to evaluate the efficacy of Escitalopram, a new kind of Selective Serotonin Reuptake Inhibitor (SSRI) in patients with CLBP in a prospective, randomized and double-blind clinical trial. The main hypothesis is: -in comparison to placebo, subjects with CLBP and Cipralex report a significant reduction in depressive symptoms (>= 50% of HAMD questionnaire) after 4 weeks of treatment.

NCT ID: NCT00221494 Withdrawn - Depression Clinical Trials

Can Additional Drug Therapy Accelerate Response Time to Antidepressants

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

Antidepressants are commonly prescribed and are effective for treating depression. However, they generally take 4-6 weeks for a therapeutic response. This study is evaluating whether simultaneous treatment with thyroid hormone or pindolol can decrease the response time ("getting better faster") in patients who are starting SSRI treatment.

NCT ID: NCT00204503 Withdrawn - Clinical trials for Bipolar I or II Depression and Alcohol Abuse or Dependence

Open-Label Depakote ER in Patients With Bipolar I or II Depression and Alcohol Abuse or Dependence

Start date: June 2003
Phase: Phase 2
Study type: Interventional

The purpose of this study is to determine if Divalproex Sodium can be used to Treat and Prevent Depression in Patients with Bipolar Disorder who have Comorbid Alcohol Dependence/Abuse.
