Filter by:This study is designed to assess the use of pramipexole dihydrochloride and quetiapine (Seroquel) XR as combination therapy for bipolar depression. The proposed benefit of the combination therapy investigated in this study is improved treatment of bipolar depression.
The proposed study is for a 6 week open-label clinical trial in which Seroquel XR is added to a selective serotonin reuptake inhibitor (SSRI) medication for the treatment of depressive and/or anxiety symptoms. Each subject will self-report changes in symptoms, functional impairment, etc. on a twice daily basis using a handheld computer (HHC) that transmits real-time symptoms reports to a central database. Each subject will be assessed in-person on a weekly or biweekly basis during the course of the study.
The primary aims of this study are to: 1. Assess the efficacy of aripiprazole augmentation for the acute and continuation treatment of TRLLD. Hypothesis 1: Patients with TRLLD (defined as those who do not remit after 12 weeks of acute treatment with venlafaxine XR) will have a higher rate of remission with aripiprazole than with placebo augmentation (primary outcome) and greater improvement in depressive symptoms and stability of remission (secondary outcomes). 2. Assess the tolerability of aripiprazole in TRLLD with a focus on adiposity and akathisia/restlessness. Hypothesis 2: Aripiprazole will be associated with a higher rate of clinically significant akathisia and increased adiposity than placebo. The Secondary/exploratory aims of this study are to: 1. Examine anxiety, medical burden, and executive impairment as moderators of aripiprazole augmentation efficacy in TRLLD. Hypothesis 3: Pre-levels of anxiety symptoms, medical burden, and executive impairment will be treatment-specific factors: they will moderate the efficacy of aripiprazole augmentation. The aripiprazole-placebo difference will be greater in individuals with these variables, compared to those without these variables because these three factors will be associated with a decreased likelihood that "staying the course" with venlafaxine monotherapy will achieve remission. 2. Examine genetic predictors (phase 1) and moderators (phase 2-3) of treatment outcomes, while controlling for drug exposure. Hypothesis 4: Selected polymorphisms will reduce remission rate with venlafaxine and will reduce efficacy and tolerability with aripiprazole.
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 to develop and pilot test two interventions that lead to at least 30% of individuals with depression presenting to primary care engaging with an Internet-based depression support group. The investigators will identify primary care patients with depression who state they have access to the Internet and are willing to consider treatment for depression. In the primary care office they will be given one of three interventions introducing them to the Internet depression support group site. The major outcome will be accessing the depression Internet support group at least once in the following four weeks. The results of this study will provide important information on whether it is possible to recruit a substantial proportion of primary care patients to engage in a potentially useful and inexpensive addition to standard depression care. If this is not possible, the likelihood of successfully completing a RCT of the effectiveness of depression Internet support groups utilizing primary care patients would be low. Researchers trying to assess the effectiveness of depression Internet support groups would have to go to alternative designs such as recruiting patients with depression as they try to join the depression Internet support groups and randomizing some to a delay in joining the group.
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 purpose of the study is to examine the effectiveness of telephone cognitive-behavioral therapy for subthreshold depression and presenteeism in workplace, in comparison with treatment-as-usual (TAU) (which is minimal contact through Employers Assistance Program (EAP)).
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).
The purpose of this study is to compare the efficacy of quetiapine fumarate monotherapy with quetiapine fumarate in combination with lithium in the treatment of a major depressive episode in patients with bipolar disorder.
The main aim of the project is to develop couple therapy for depression with special interest in dialogical and narrative processes in therapy. Parenthood, and different psychosocial phenomena, such as domestic violence, suicidal behaviour and alcohol abuse in relation to the client's specific depressive state will be analysed. The second main aim of the study is to analyse the effectiveness couple therapy for depression as a real world study. The good and poor outcome of different therapy processes will be compared and thus information about precise change processes will be reached. Owing to the real world setting, the inclusion criterion is a broad one: a primary diagnosis of depression (F32 and F33 in ICD-10). The project will be conducted as a multicentre study so that in each centre the included patients will be randomized into experiment and control groups. The study centres are (1) Pohjois-Savon sairaanhoitopiiri in Kuopio, (2) Länsi-Pohjan sairaanhoitopiiri in Tornio and Kemi and (3) HUS/ Jorvin sairaala regional psychiatric polyclinics in Espoo. In each province the entire adult population has free access to the psychiatric outpatient clinics in their specific catchment area and thus no selection for the patients is done.
