Active clinical trials for "Depressive Disorder"

Ketamine infusion has been shown to have rapid antidepressant properties, however the possible use of ketamine in treatment-resistant depression as augmentation has not been investigated. The overall aim of this study is to assess the feasibility, safety and tolerability, efficacy and duration of the effect of intravenous N-methyl-D-aspartate antagonist ketamine as augmentation of antidepressants for chronic suicidal ideation in subjects with severe treatment-resistant depression (TRD). This is an open-label study (pilot).

The purpose of this study is to conduct a pilot randomized controlled trial (RCT) that provides the feasibility, safety, and preliminary efficacy data required to design a large scale trial evaluating Tai Chi for Chinese Americans with major depressive disorder (MDD) who are not on antidepressant medications.

The proposed study is a 1-week, randomized, double-blind, placebo-controlled, trial to evaluate the efficacy of an IV infusion of magnesium sulfate on symptoms of treatment resistant mild and moderate depression in 20 males and females (21-70 years of age). Participants will be assessed at screening/baseline, day 1, day 2, day 7, and day 8. Each subject will be randomized in a double-blind fashion to receive either IV infusion of magnesium sulfate or 5% dextrose followed by a washout period of 5 days then crossover to receive either IV infusion of 5% dextrose or magnesium sulfate.

Safety and Efficacy of Vilazodone in Major Depressive Disorder

The purpose of this study is to assess the efficacy of esketamine compared with placebo in improving symptoms of depression in patients with treatment resistant depression.

This research study will examine whether elderly depressed patients whose depressive symptoms do not respond satisfactorily to therapy with a mood stabilizer or antidepressant alone gain any benefit from taking minocycline alone or in addition to their antidepressant or mood stabilizer medication. Minocycline is a commonly used antibiotic medication with anti-inflammatory properties. It is hoped that information gained from this study will help the investigators better understand the role of inflammation in depression, and whether decreasing inflammation will lead to improvement in the symptoms of depression and cognitive function.

Patients presenting with depression (DEP) and cognitive impairment (CI), represent a unique, understudied population that is difficult to diagnose, treat and estimate prognosis. Our pilot data, supported by the literature, suggest that many DEP-CI patients show cognitive decline and often convert to dementia, primarily Alzheimer's disease (AD). In DEP-CI, there is a lack of data on treatment response of mood symptoms to antidepressant treatment and particularly of cognitive deficits to cognitive enhancer treatment. Our initial pilot data in a double-blind study showed that donepezil was superior to placebo in improving memory in antidepressant-treated DEP-CI patients. In a second pilot study, open label es-citalopram plus memantine treatment led to a low rate of conversion to dementia. In this proposed pilot clinical trial, the investigators will evaluate, treat and follow a broad sample of 80 DEP-CI patients at NYSPI/Columbia University Medical Center (N = 40) and Duke University Medical Center (N = 40). Recruitment will be from clinics and/or advertisements. In the treatment protocol, all 80 DEP-CI patients will receive baseline mood and memory assessments and open antidepressant treatment with citalopram for 8 weeks. At 8 weeks, repeat assessment will occur and patients whose depression has responded to citalopram will be randomized to add-on donepezil or placebo. Non-responders to citalopram will receive open treatment with venlafaxine and will be randomized 8 weeks later (16 weeks of open antidepressant treatment) to add-on donepezil or placebo. Patients will be followed for a total period of 18 months with continuous open antidepressant treatment during the trial. Donepezil is being studied in order to increase the likelihood of obtaining a signal. If the results are positive, the investigators can begin clarifying the mechanism(s) in subsequent trials. Baseline apolipoprotein E e4 genotype, odor identification deficits, and MRI hippocampal and entorhinal cortex atrophy will be explored as predictors of donepezil response in the 18-month trial. Improving cognition and delaying conversion to a clinical diagnosis of dementia in this high risk group will enhance quality of life, reduce family burden, and markedly diminish overall health care costs.

The objectives of this study were to examine the cardiovascular sensitivity to oral tyramine after establishment of steady state with CX157 Modified Release (MR) Tablets, 125 mg administered twice per day (BID) in healthy volunteers compared to placebo; and to investigate the general safety, tolerability and pharmacokinetic profile of CX157 tablets at steady state compared to placebo.

This study is looking at the safety and efficacy of low field magnetic stimulation (LFMS) for treating patients with treatment resistant depression who are taking an antidepressant that is not working for them.

The Institute of Medicine identifies Prolonged Grief (PG) as a critical under-addressed public health problem for which are no empirically supported treatments. The purpose of this application is to pilot-test Behavioral Activation (BA) therapy for PG. BA is a well supported, stand alone intervention for depression and recently applied to posttraumatic stress disorder, which reduces rumination and avoidance behaviors that otherwise thwart access to natural rewarding contingencies and resources. The treatment focuses on promoting stable, active routines, self-care behaviors, enhanced self-efficacy, and reengagement with pleasurable activities and significant social resources. Rumination, disengagement, and low self-efficacy are defining features of PG. Further, in response to loss of intimates, the key factors that differentiate resilient people from those that have difficulties adapting is the maintenance or fast resumption of social and occupational functioning. Thus, the main hypothesis of this study is that BA for PG will result in clinically significant reductions in rumination and functional disengagement. This is a preliminary small-scale pilot assessment of potential efficacy and feasibility of completing a large scale study of BA for PG.
