Active clinical trials for "Depressive Disorder"

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.

The purpose of this study is to determine whether estrogen patches are effective for the treatment of postpartum major depression, as compared to sertraline (Zoloft) and placebo.

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 study hypothesis is that the addition of an antidepressant to the standard treatment regimen in patients with both chronic sinusitis and depression or facial pain disorders and depression will decrease the report of chronic sinusitis or facial pain symptom severity. This is a stratified, randomized, double-blind, placebo-controlled study using the drug escitalopram for the treatment of depression in patients experiencing depression and chronic sinusitis or depression and facial pain disorders. It is a 12-week study. Subjects will have a screening visit and then be followed up by phone weekly for four weeks and bi-weekly for 8 weeks.

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 investigate whether the addition of galantamine to a commonly used antidepressant, escitalopram (Lexapro), will be useful in the treatment of memory and other thinking problems that are frequently seen in depression. At present, galantamine is approved for use in the treatment of Alzheimer's disease or dementia, but not for use for the treatment of depression in younger patients. Possible genetic effects of depressed individuals will also be studied. This study is involved in collecting blood from patients with depression. DNA, the genetic material in our cells, will be obtained from these blood samples. The DNA will be studied to determine the contribution of different genes to the development of depression. These blood samples are extremely useful to researchers who are trying to determine the genetic risk factors that may lead to depression.

This study will report on the outcomes of rTMS administered 3 times per week, compared with the standard protocol of 5 times per week. Participants will be randomly assigned to frequency condition and depressive symptomatology will be measured weekly using a range of clinician and self-rated questionnaires. Participants will remain in the study for at least 4 weeks, with the option of continuing for a further 2 weeks as judged by the study psychiatrist. It is hypothesised that rTMS administered three times per week will be equally as effective as rTMS administered five times per week in reducing depressive symptomatology.

The goal of this study is to determine whether indiplon, when administered with sertraline, improves insomnia symptoms and depressive symptoms in subjects with both insomnia and depression.

Individuals with bipolar depression who had a particular kind of brain imaging reported improved mood after the imaging. This effect may be linked to the changing magnetic fields used during these magnetic resonance imaging studies. The current studies are designed to further explore the important parameters of this effect and to clarify the degree and duration of the mood effects.
