Filter by:The primary purpose of this study is to compare the long-term efficacy and safety of desvenlafaxine succinate sustained release versus placebo in adults with Major Depressive Disorder, using a randomized withdrawal design. Randomized withdrawal means that after receiving desvenlafaxine succinate sustained release for a predetermined period of time, subjects will be selected by chance to either continue receiving the study drug or to be withdrawn from the study drug and receive placebo for the remainder of their participation in the trial. Subjects will not know to which group they have been assigned. The study consists of an up to 14-day screening period followed by an 8-week open-label period in which subjects will knowingly receive 50 mg/day of desvenlafaxine succinate sustained release. Subjects who do not respond to treatment, demonstrating no significant change in their depressive symptoms, will be withdrawn from participation at the end of this period. Responding subjects will receive an additional 3 months of open-label desvenlafaxine succinate sustained release at the same dose. Subjects with stable response to treatment at the conclusion of this 3 month period will be randomized to either desvenlafaxine succinate sustained release at 50 mg/day or placebo in a blinded manner for an additional 6 months or until symptoms of depression return. Following discontinuation at any point after enrollment in the study, subjects will receive two weeks of follow-up monitoring, including one week of blinded taper with 25 mg/day of desvenlafaxine succinate sustained release treatment for any subjects who have been taking desvenlafaxine succinate sustained release prior to discontinuation. Subjects assigned to placebo will receive a blinded placebo taper. Following taper, subjects will be evaluated for one additional week to monitor safety.
The purpose of this study is: 1. To determine, in the context of a prospective clinical trial, whether stimulation parameters in PD patients treated with DBS, are associated with antidepressant effects. 2. To determine whether these antidepressant effects are related to or independent of changes in the motor features of PD. 3. To establish a computerized database that includes stimulation parameters and clinical parameters in PD patients treated with DBS. 4. To develop a computer-assisted decision making protocol for programming of DBS parameters in both depressed and non-depressed PD patients.
The primary aim of this study is to examine whether adolescent depression and the family context in which it develops is best treated using an individual adolescent intervention or an intervention that includes both the adolescent and the parents. This will be accomplished by conducting a randomized controlled pilot study of Interpersonal Psychotherapy for Depressed Adolescents (IPT-A) in comparison to Interpersonal Psychotherapy for Depressed Adolescents and Parents (IPT-AP).
To examine the safety and efficacy of long term administration of aripiprazole as an adjunctive therapy, co-administered with either a selective serotonin reuptake inhibitor (SSRI) or a selective-norepinephrine reuptake inhibitor (SNRI), in subjects with major depressive disorder.
To examine the efficacy and safety of aripiprazole versus placebo as an adjunctive therapy co-administered with either an selective serotonin reuptake inhibitor (SSRI) or a serotonin-norepinephrine reuptake inhibitor (SNRI) in patients with major depressive disorder.
FDA has accepted atypical antipsychotics of olanzapine and aripiprazole as the adjuvant medications for refractory major depression. But there is still no trial about atypical antipsychotics combined with antidepressant of SSRI used in fresh major depressive patients. This project aims to compare the efficacy and tolerability of sertraline with or without low-dosed aripiprazole added in fresh major depression.
This study is a randomized, controlled trial of Mindfulness-Based Cognitive Therapy (MBCT) versus Health-Enhancement Program (HEP) for patients with treatment-resistant major depressive disorder (MDD). Both arms of the study will continue to receive the standard medication management treatment as usual (TAU) throughout the study. MBCT is a new technique that has been found to be effective for prevention of relapse in individuals in complete recovery from depression. MBCT is a group-based, 8-week intervention that uses mindfulness meditation as its core therapeutic ingredient. It teaches people to have a different relationship to depressive thoughts and feelings. This study will use an active condition called the Health Enhancement Program (HEP) which was specifically developed to serve as a comparison condition for mindfulness interventions. HEP has been shown to decrease global stress levels and to increase perceived health. Stress has been considered a contributor to depression. One hundred and seventy four patients with MDD who have failed two or more adequate antidepressant trials will be identified and randomly assigned to one of two groups: MBCT+TAU or HEP+TAU. All patients who enroll in the study will undergo follow-up assessments at 3, 6, 9 and 12 months following the intervention. A supplemental portion of the study will enroll 88 patients to undergo functional magnetic resonance imagining (fMRI) scans immediately before and after treatment to better understand the neural pathways implicated in depression and those that may be affected through treatment.
Electroconvulsive Therapy (ECT) remains essential to contemporary psychiatric practice and is one of the safest and most effective treatments available for depression. Despite modern advances in pharmacotherapy, about 15-20 per cent of all hospitalised patients receive treatment with ECT. Its use, however, is limited by concerns over associated cognitive side effects. Recent research has suggested that using an ultrabrief pulsewidth with ECT may greatly reduce cognitive side effects, while maintaining efficacy (Sackeim et al 2008). Preliminary results were positive for unilateral ECT, however, suggest that for bilateral ECT, dosing may need to be adjusted to preserve efficacy while reducing side effects. This study will examine the relative cognitive side effects and efficacy of right unilateral and bilateral ECT given with a standard pulsewidth or an ultrabrief pulsewidth. Some participants will also receive an MRI scan before and after ECT.
Among antidepressant treatments, Electroconvulsive therapy (ECT) stands as the most effective in treating acute depression. However, patient concerns with the cognitive side effects of ECT have encouraged the development of new and more focal forms of brain stimulation such as transcranial Direct Current Stimulation (tDCS). The investigators' current study of tDCS as a treatment for depression suggests that this technique has antidepressant effects and is safe, painless and well tolerated. However, not all patients may respond to this treatment and the concern of possible relapse in some patients who respond to tDCS has raised interest in finding treatments that may enhance and prolong the antidepressant effects of tDCS. This study will investigate whether D-Cycloserine, a medication shown to lengthen the effects of tDCS on brain activity, can also enhance/prolong the antidepressant effects of tDCS in people suffering from depression.
This is a randomized, double-blind, placebo-controlled, parallel group study to evaluate the efficacy of controlled-release (CR) formulation of paroxetine orally administered to patients with major depressive disorder (MDD) at a dose level in the range of 25 - 50 mg/day (initial dose level, 12.5 or 25 mg/day) once daily after evening meal for 8 weeks based on the decrease in HAM-D (Hamilton Depression Rating Scale) total score, to evaluate the safety based on adverse events, laboratory data and vital signs, and to describe the efficacy and safety of immediate release (IR) formulation of paroxetine.
