Active clinical trials for "Depressive Disorder, Major"

This study aims to determine whether the GeneSight Psychotropic test can result in better treatment outcomes for patients with treatment-naive major depressive disorder

According to the 2005 National Comorbidity Survey-Replication study, approximately 20.9 million American adults, or 9.5 percent of the population over the age of 18 suffer from mood disorders including major depressive disorder, chronic, mild depression and bipolar disorder. Major depressive disorder (MDD) is predicted to be the second leading cause of disability worldwide by the year 2020; sub-clinical mood disturbances impact many additional people and are a major reason people seek psychotherapy services. The economic burden of depression in the United States is significant: $83.1 billion in 2000 and increasing. Much of this burden comes from the high rate of sub-optimal treatment outcomes associated with the disorder. Indeed, only 50% of MDD patients recover in less than 12 weeks with adequate treatment, and up to 20% of patients will fail to adequately respond to all currently available interventions. Moreover, current treatments come at the cost of significant central nervous system (CNS) side effects, further highlighting the need for more effective treatments with fewer side effects. To address these pressing clinical issues, the investigators will conduct a placebo controlled, clinical trial to determine if Whole Body Hyperthermia (WBH) enhances the effects of psychotherapy compared to psychotherapy alone in medically healthy patients with moderate to severe mood disorders. The investigators plan to recruit a sample of 24 medically healthy individuals with mood problems who will be randomized to examine whether WBH enhances the effects of psychotherapy. To determine acute and sustained effects of WBH +psychotherapy on mood disorders, the study will include basic psychiatric questionnaire-based assessments at three therapy sessions prior to a single session conducted while receiving one of two intensities of WBH treatment. Subjects who elect not to conduct a therapy session in the WBH chamber will still be able to complete study questionnaires at all therapy sessions. This study challenges the existing paradigm by determining if peripheral afferent sensory pathways can be accessed to enhance the treatment of mood disorders and thus avoid problems of exposing all of the brain to non-selective drugs.

This is a 6-week, randomised, multicenter, double-blind, placebo controlled, fixed dose parallel group study to assess the efficacy and safety of orvepitant (30 and 60 mg/day) versus placebo in subjects with a diagnosis of a Major Depressive Disorder, whose symptoms are considered moderate or severe. Following an initial screening visit, subjects fulfilling the study inclusion and exclusion criteria will enter a pre-treatment screening phase to permit evaluation of the laboratory and ECG assessments and to confirm eligibility for inclusion into the study. This screening phase will be a minimum of 7 days, but no longer than 21 days. At the completion of the screening period, eligible subjects will be randomised at the baseline visit to receive either orvepitant 30mg/day, orvepitant 60mg/day or placebo (equal chance of receiving any of the three possible treatments, i.e., a 1:1:1 ratio) for a six-week double-blind treatment phase. Those subjects randomised to receive placebo will receive study medication identical in appearance to that received by subjects assigned to receive orvepitant 30 or 60mg/day. Efficacy will be assessed via standard depression symptom and severity rating scales or questionaires. The Hamilton Depression Rating Scale (HAM-D) will be used as the primary measure. Secondary efficacy endpoints include the Quick Inventory of Depressive Symptomatology (QIDS-SR) and the Clinical Global Impression- Global Improvement and Severity of Illness Scale (CGI-I and CGI-S, respectively). Safety will be assessed by monitoring for adverse events (side effects) and through periodic laboratory evaluations (blood tests), vital signs assessments (e.g., blood pressure, heart rate, temperature) and heart function measurements (electrocardiograms, or ECGs).

The purpose of this study is to determine a dose of the investigational drug betahistine dihydrochloride that is both well tolerated and potentially effective in treating the symptoms of atypical depression. Atypical depression is characterized by the ability of the person's mood to improve temporarily in response to positive events, as well as features such as increased appetite, increased sleep and severe fatigue.

The purpose of this study is to determine whether cognitive behavioral therapy (CBT) is effective in the prevention of depression during interferon and ribavirin treatment for hepatitis C infection.

The purpose of this study is to examine whether the speed of the clinical antidepressant action of fluoxetine can be accelerated by administering DU125530 a full 5-HT1A antagonist.

The purpose of this study is to evaluate the effectiveness and safety of JNJ26489112 compared with an active control (Venlafaxine XR) and placebo in patients with Treatment-Resistant Major Depressive Disorder.

A six week, fixed dose, double-blind, double-dummy, placebo, and active controlled, multicentre trial to evaluate the safety and efficacy of CP-316,311 in outpatients with major depressive disorder.

The study will evaluate the efficacy, safety, and tolerability of 450 milligrams (mg) of Rapastinel, compared to placebo in adult patients with major depressive disorder (MDD) who are at imminent risk of suicide.

INTRODUCTION: There is strong evidence indicating the effectiveness of Cognitive-Behavior Therapy (CBT) in the management of Major Depressive Disorder (MDD) and some clinical trials indicating physical exercise (PE) as an effective treatment for the disorder. However, few studies have evaluated the effect of group CBT or PE compared to wait-listing to receive treatment as usual (TAU) in the management of MDD. This study will evaluate and compare the effectiveness of: 1) group CBT plus wait-listing for TAU; versus 2) group PE plus wait-listing for TAU; versus 3) only wait-listing for TAU in management of MDD. The investigators hypothesize that participants with MDD assigned to the group CBT or PE (plus wait-listed for TAU) arms of the study will achieve superior outcomes compared to participants only wait-listed for TAU. METHODS AND ANALYSIS: This is a prospective rater-blinded randomized controlled trial assessing the benefits for participants with MDD. 120 patients with MDD referred to Addiction and Mental Health (AMH) clinics in Edmonton Zone who are informed about the study and consent to participate will be randomly assigned to one of the 3 arms of the study: 1) 40 participants wait-listed for TAU will receive weekly sessions of group CBT for 14 weeks; 2) 40 participants wait-listed for TAU will receive PE 3 times a week for 14 weeks; and 3) 40 participants will only be wait-listed for TAU. Participants will be assessed at enrollment, 3 and 6 months post enrolment, mid-treatment, and at treatment completion . Their assessments will cover primary outcomes including functional variables (relationships, well-being, physical activity) and symptom variables (changes in depressive symptoms scores). Secondary client outcomes will be service variables (e.g. patient compliance, retention in treatment, patient satisfaction). In addition, participants in the intervention groups will be evaluated weekly with one functional measure. The data will be analyzed using repeated measures and effect size analyses, and correlational analyses will be completed between measures at each time point. ETHICS AND DISSEMINATION: The study will be conducted in accordance with the Declaration of Helsinki (Hong Kong Amendment) and Good Clinical Practice (Canadian Guidelines). Written informed consent will be obtained from each subject. The study has received ethical clearance from Health Ethics Research Board of the University of Alberta (Ref. # Pro 00080975) and operational approval from the provincial health authority (AHS # 43638). The results will be disseminated at several levels, including patients, practitioners, academics/researchers, and healthcare organizations.
