Active clinical trials for "Depressive Disorder"

The purpose of the study is to assess the efficacy of DEPREXIL administration in combination with relaxation psychotherapy in the treatment of patients with signs and symptoms of depression. The duration of this double-blind placebo controlled phase 3 clinical trial will be 24 weeks. The estimated number of persons to be recruited and randomized for the study is 200.

Major depressive disorder (MDD) continues to have a profound impact on individuals, families, and the health care system. Despite marked success in treating active individual episodes of unipolar depression, our understanding of the neural and cognitive mechanisms involved in the return of symptoms remains extremely limited, and few interventions exist that specifically target factors involved in prophylaxis. The research being proposed is among the first that is designed to examine neurocognitive markers for depressive relapse vulnerability and link them directly to clinical prognosis. Hypothesis 1: Cortical midline structures (CMS) network recruitment will be associated with behavioural and neural indices of a reflexive attentional bias towards dysphoric stimuli in a divided attention task. Hypothesis 2: Behavioural and neural indices of dysphoric attentional bias following mood challenge will predict depression relapse in prospective 18-month follow up. Hypothesis 3: Relative to CBT, Mindfulness Based Cognitive Therapy (MBCT) will normalize CMS and right insular/fronto-opercular cortices (INS-FO) network imbalance. Hypothesis 4: Relative to CBT, MBCT will normalize to healthy control levels, behavioural and neural indices of dysphoric attentional bias, which will be predictive of reduced relapse risk across a 24 month follow up.

Treatment resistant depression (TRD) is a major public health problem. Current therapeutic options for this patient population remain limited. With all available treatments, only a sub-set of those patients who achieve an antidepressant response are likely to achieve treatment-induced remission. The need for antidepressant medication that can provide both rapid and long lasting relief of TRD symptoms is widely recognized. There is new evidence that drugs that block NMDA glutamate receptors (NMDA antagonists) are promising candidates for meeting this need. Existing studies in TRD have used only a low-dose, brief infusion of ketamine that would not be expected to re-sensitize the NMDA receptor; in agreement with this theory, these prior studies have found only temporary improvements of depression. Our key hypothesis is that a higher-dose, longer-term ketamine infusion, such as that used in chronic pain studies, would provide a more robust and lasting improvement from depression. Accordingly, we will test whether a 100-hour ketamine infusion would be more effective than the standard 40-minute ketamine infusion currently used in other TRD studies. We will randomize subjects to one of 2 arms: (1) 100-hour (+/- 4 hours) ketamine infusion plus clonidine for the entire infusion (2) 40-minute ketamine infusion (plus clonidine) following a 100+/- hour saline infusion. All subjects will receive clonidine, an alpha-2 agonist, to minimize side effects of ketamine (namely, brief/mild psychotic and cognitive symptoms).

The purpose of this study is to evaluate the effect of liver function on how much of the study drug (LY2216684) gets into the blood stream and how long it takes the body to get rid of it. Information about any side effects that may occur will also be collected. The duration of participation in this study is approximately 12 days, not including the screening visit. This study requires 1 clinic confinement of 5 days/4 nights followed by 1 out-patient follow-up visit. A screening visit is required within 30 days prior to the start of the study. This research study will be an open-label study. The study involves a single oral dose of 18 milligrams (mg) LY2216684 given as 2 tablets.

In summary, the investigators propose to integrate fMRI assessments within a clinical trial of quetiapine XR in patients with melancholic depression in order to test the predictions that: quetiapine XR treatment will be effective and safe for patients with major depression with melancholic features successful treatment with quetiapine XR will be associated with normalization of limbic areas associated with increased salivary cortisol response to a stressful task as well as normalization on the emotional faces task differences in the melancholic group compared with healthy volunteers. successful treatment with quetiapine XR will be associated with normalization of the salivary cortisol response to the stressful math task (i.e. there will be a diminished post-treatment mean AUC for cortisol secretion after the stress task compared to the pre-treatment AUC values in the patient group)

This study will aim to examine the use of external trigeminal nerve stimulation (TNS) as an adjunctive treatment for adults with major depressive disorder (MDD) when added onto antidepressant medications. Our primary objective is the examination of two different "doses" of TNS, in terms of pulse frequency. To accomplish our specific aims, the investigators will test the following specific hypotheses: Subjects will show greater improvement in ratings of mood and other symptoms of depression during the six-week of high frequency stimulation than during low frequency stimulation periods. Subjects will show greater improvement after 12 weeks of high frequency stimulation than after six weeks of high frequency stimulation. Subjects will show improvement in ratings of life functional capacity and quality of life with TNS. Subjects will report the TNS treatments to be acceptable in terms of side effects and burden of using the device. Subjects will show significant differences in regional brain function at the end of the high frequency stimulation period compared with baseline, and significant differences between high and low frequency stimulation conditions.

The purpose of this study is to determine whether minocycline and aspirin are effective in the treatment of depression in individuals with bipolar disorder.

The purpose of the study is to investigate the effect of tDCS applied at the anodic left DLPFC of patients with resistant depression compared to patients treated with conventional therapy. The tDCS is used in add-on drug treatment with antidepressants of reference in resistant depression.

Major Depressive Disorder (MDD) is a severe and common psychiatric disorder. Although MDD primarily involves mood disturbances, patients also usually present alterations in cognitive function (attention, memory, executive functioning and psychomotor speed). Even though antidepressants are suggested in the literature to potentially improve cognitive dysfunction in patients with MDD to some degree, there is a lack of adequate and well-controlled studies to investigate this effect. This study will evaluate the efficacy, safety and tolerability of a new antidepressant Vortioxetine versus placebo on cognitive dysfunction in adult patients with MDD.

This project will integrate a depression treatment and brief medication adherence counseling intervention into clinical care at three HIV clinics and will use a randomized controlled trial to assess whether, relative to usual care, the intervention leads to improved HIV medication adherence. The depression treatment intervention uses a model known as Measurement-Based Care which equips Depression Care Managers with systematic measurement tools, a decision algorithm, and psychiatric backup and trains them to provide decision support to HIV clinicians to implement, monitor, and adjust antidepressant therapy.
