Filter by:The main research hypothesis for this study is that, among patients with Major Depressive Disorder (MDD) who have responded inadequately to treatment with SSRIs or SNRIs, the degree of improvement, as measured by the change from baseline of the Montgomery-Asberg Depression Rating Scale (MADRS)will be significantly greater among patients treated with EB-1010 (at the dose of 50 mg/day or 100 mg/day) than among those treated with placebo using the sequential parallel comparison design. The secondary research hypothesis for this study is that, among patients with MDD who have responded inadequately to treatment with SSRIs or SNRIs, the degree of improvement in depressive symptoms, as assessed by the MGH Cognitive and Physical Functioning Questionnaire (MGH CPFQ) will be significantly greater among those treated with EB-1010 (50 mg/day or 100 mg/day) than those treated with the SSRI paroxetine.
The overall objective of this trial is to demonstrate clinically relevant superior antidepressant efficacy of the fixed dose combination PNB01 (low dose pipamperone and citalopram) over reference antidepressant treatment with citalopram alone, and a low dose of psychoactive pipamperone alone in patients with moderate to severe Major Depressive Disorder. This study was specifically designed to assess patient related outcome (PRO) parameters using an Interactive Voice Response System (IVRS) via telephone.
The primary object of this study is to confirm the superiority of tianeptine compared to escitalopram on effects that improves subjective and objective cognitive impairments in patients suffering from major depressive disorder.
The study evaluated the long-term safety of Desvenlafaxine Succinate (DVS) Slow Release (SR) during open-label treatment in adult outpatients who had a primary diagnosis of major depressive disorder (MDD). The study also evaluated the long-term response of subjects receiving DVS SR for clinical global evaluation, functionality, general well-being, pain, and absence of depressive symptoms (remission).
The focus of this study is to gather preliminary data regarding the effects of a psychological therapy-Problem Solving Therapy-and an antidepressant medication-sertraline-on 1) cerebral perfusion (CP), 2) brain derived neurotrophic factor (BDNF), and 3) measures of cognitive function in subjects with late life major depression (LLMD). This research goal will be achieved by recruiting 38 individuals over the age of 65 with LLMD. The primary outcomes will be change in CP, change in BDNF, and change in cognitive measures from baseline to the end of 12 weeks of either therapy. We will also examine predictors of treatment outcome including severity of executive dysfunction, baseline BDNF concentrations, and baseline CP measures. The baseline neuropsychological testing, brain imaging, and depression assessment will be obtained in a companion study (PI S. Mackin; CHR #H42689-32681-01) that is IRB approved and is already in progress. In the current study a baseline serum BDNF level will be added to Dr. Mackin's protocol. Patients will then receive either 12 weeks of Problem Solving Therapy or antidepressant treatment with sertraline. Both treatments are evidence based and commonly administered in our clinic. Outcome variables will be measures of depression severity, the BDNF serum concentration, cerebral perfusion using a MRI arterial spin labeling (ASL) technique and cognitive changes in memory and executive dysfunction. This is a preliminary or pilot study. The primary objectives are to determine if the methods appear feasible and to determine if change in BDNF or CP occur after treatment and secondarily to determine if there are changes in cognitive functioning. The study is not powered to show differences between treatments. The hypotheses are 1) PST will result in increased perfusion in frontal regions of the brain but that frontal perfusion will not change with sertraline; 2)sertraline will result in an increase in BDNF but PST will not. Change in cognitive measures of memory, learning, and executive dysfunction will be examined on an exploratory basis.
The objective of the current study is to investigate the safety and efficacy of a single dose of intranasal (IN) ketamine in treatment-resistant depression (TRD).
The primary objective of this study was to assess the maintenance of efficacy of LY2216684 compared with placebo as adjunctive therapy to selective serotonin reuptake inhibitors (SSRIs) as measured by the time-to-symptom reemergence among participants with major depressive disorder (MDD) who met randomization criteria with adjunctive LY2216684 during the stabilization period. This trial consists of two distinct periods: an open-label treatment period, which consists of two parts, 8 weeks acute open-label with movement to 12 weeks open-label stabilization if participants are in remission at end of 8 weeks (open-label for 20 weeks total) followed by a randomized, double-blind, placebo-controlled period for 24 weeks.
The purpose of this study is to determine how much lorazepam gets into the blood and how long it takes the body to get rid of it when given together with LY2216684. Information about any side effects that may occur will also be collected.
The purpose of this study is to determine whether RX-10100 are effective in the treatment of Major Depressive Disorder (MDD).
The purpose of this study is to get a better understanding of the side effect burden and identify predictors of psychotic, mood and aggressive disorders in children and adolescents. The study's primary aim is to identify genetic risk factors for weight gain and metabolic abnormalities.
