Active clinical trials for "Depression"

The purpose of this study is to evaluate the anti-depressive efficacy of mirtazapine in depression induced by peginterferon alpha-2a and ribavirin treatment in Korean patients with chronic hepatitis C.

This is a prospective, multi-center, open-label study in Relapsing-remitting Multiple Sclerosis (RRMS) patients with mild to moderate depression treated with selected serotonin reuptake inhibitors (SSRI) or serotonin and norepinephrine reuptake inhibitors (SNRI) antidepressants over 16 weeks as add-on to fingolimod treatment. It is designed to evaluate the safety and tolerability of this combination in this patient population based on an immunomodulatory treatment with fingolimod.

We are doing this research study to find out if people who get better while taking a specific kind of antidepressant medication (a selective serotonin reuptake inhibitor, or SSRI) and people who get better while taking placebo (an inactive substance) have similar chemicals in their brains. Some participants may complete a procedure called Acute Tryptophan Depletion (ATD), which is a way to study the role of serotonin in depression. Some participants may also undergo a magnetic resonance-positron emission tomography (MR-PET) scan.

The proposed study will evaluate the response and remission rates for major depressive disorder (MDD) in end-stage renal disease (ESRD) patients undergoing maintenance hemodialysis (HD) treated with bupropion or fluoxetine for 12 weeks. In addition, the study will document the relative tolerability and safety, and longitudinally contrast the effects of bupropion and fluoxetine on measures of cognitive function, fatigue, inflammation, and tryptophan (TRP) and TRP catabolites in blood. It is hypothesized that both drugs will significantly reduce MDD symptoms from baseline, and be tolerable and safe, but bupropion will be associated with greater reduction in pro-inflammatory cytokines, cognitive impairment, and fatigue compared with fluoxetine. The Specific Aims of this study are: Aim 1: Determine the efficacy of bupropion and fluoxetine in treatment of MDD in ESRD/HD patients. Aim 2: Determine whether longitudinal change in MDD symptoms, cognitive dysfunction, and fatigue differ between bupropion and fluoxetine. Aim 3: Determine whether longitudinal change in MDD symptoms, cognitive dysfunction, and fatigue correlate with change in inflammation, measures of TRP availability to brain, or neurotoxic TRP metabolites. Hypotheses: Bupropion and fluoxetine will both show efficacy in treating MDD; Bupropion will lead to greater improvement in cognitive dysfunction and fatigue than fluoxetine; and Change in cognition and fatigue over time will correlate with change in c-reactive protein (CRP) and quinolinic acid and change in overall depression score will correlate with measures of TRP availability.

This study is a 4-week, randomized, double-blind, parallel-group, placebo-controlled monotherapy study in patients with treatment-resistant major depression. After confirmation of treatment-resistance in a prospective treatment period with citalopram, each patient will be treated with either EVT 101 once daily or placebo for 28 consecutive days.

Targeting the glutamatergic system to treat depression is a new and promising strategy based on studies at the molecular, synaptic, and neuronal level but also on results of studies conducted in animal models and first clinical studies involving depressed patients.Ketamine has been proposed as a novel approach to induce rapid antidepressant response. In this pilot project the investigators aim to introduce this novel and promising approach into clinical practice. Besides the assessment of clinical efficacy, the investigators will put a special emphasis on the assessment of ketamine-associated effects on brain function using fMRI and cognitive testing.

The primary objectives of the study are to test whether brain Mono Amine Oxidase-A (MAO-A) levels are elevated in patients with treatment-resistant major depression, and to explore whether MAO-A brain levels predict treatment outcome with Mono Amine Oxidase Inhibitor (MAOI) medication in this population.

This is an 8-week open label study of bupropion SR in the treatment of youth with bipolar depression with adequate mood stabilization. All youth will be closely monitored for treatment emergent manic activation and drug-drug interactions with ongoing antimanic agents. The main objective of this study is to assess the safety and effectiveness of bupropion SR in the treatment of bipolar depression in children and adolescents.

This study will evaluate the efficacy and safety of different doses of Lu AA34893 in the treatment of depression in patients with bipolar disorder.

GW856553 is a novel compound, currently in development for the treatment of Major Depressive Disorder (MDD), and other indications. GW856553 inhibits a protein which is responsible for the production of some pro-inflammatory molecules, called cytokines. Increased blood levels of these molecules were seen in populations of MDD patients and this was more apparent in subjects with severe symptoms, psychomotor retardation and loss of energy. Aim of the present study is to assess whether GW856553, by inactivating this protein, is able to suppress the production of the cytokines, and ultimately relieving depression symptoms. In this study GW856553 or placebo is given to MDD patients 7.5md twice daily for 6 weeks.
