Filter by:The study will evaluate the effect of Clarithromycin on the pharmacokinetics (PK) of LY2216684 in healthy participants. Side effects will be documented. There will be 2 study periods (5 and 9 days) and follow up will occur at least 7 days after the last dose. Screening is required within 45 days prior to the start of the study.
The study will evaluate how genetic profiles respond to LY2216684 and the effect of Quinidine on the pharmacokinetics (PK) of LY2216684 in a specific genetic profile. Side effects will be documented.
Although treatment guidelines manifest that antidepressant response usually appear with a delay of several weeks and suggest that treatment should be changed if a partial response has not occurred after 4~6 week, these beliefs are no longer held by experts, and a new concept is raised that the first 2 weeks of treatment may be a useful strategy for improving the management of depression. New evidence indicates that early treatment response can be predicted with high sensitivity after 2 weeks of treatment in patients with major depressive disorder (MDD). Early improvement not only predicted response or remission, but also that lack of improvement was associated with little chance of response if the treatment strategy remained unchanged. The criterion of a 20% score reduction has been chosen as an early indicator of improvement because it can be reliably measured in clinical trials and translates into a clinically relevant change in the severity of depressive symptoms. Antidepressants that enhance both serotonergic and noradrenergic neurotransmission may be more effective than selective serotonin reuptake inhibitors (SSRIs) for acute-phase therapy of major depressive disorder. As a noradrenergic and specific serotonergic antidepressant, the antidepressive mechanism of mirtazapine is quite superior to SSRI and in particular has been suggested to have a faster onset of action than SSRIs in MDD patients. The aim of this study is to provide physicians with further information regarding early improvement and the effectiveness of mirtazapine combined with a SSRI antidepressant therapy in nonresponders.
This multi-center, randomized, double-blind, placebo-controlled, parallel-group study will investigate the efficacy and safety of RO4995819 as adjunctive therapy in patients with major depressive disorder having inadequate response to ongoing antidepressant treatment. Patients will be randomized to receive once daily doses of 5 mg, 15 or 30 mg of RO4995819 or matching placebo. The anticipated time on study treatment is 6 weeks.
The purpose of this study is to predict and visualize sertraline treatment response in major depressive disorder with clinical symptoms, demographic and stress state, personality, eight genetic polymorphisms at baseline.
The purpose of this study is to assess the long-term safety, tolerability and efficacy of oral OPC-34712 as adjunctive therapy in the treatment of adult patients with Major Depressive Disorder (MDD).
The main objective of this observational study is to characterize new users of quetiapine XR as well as new users of other study drugs (i.e. the comparison group) and to quantify the risk of developing newly diagnosed outcomes of interest in new users of quetiapine XR as well as in other study drugs.
A retrospective study using a data base of anonymized medical records. The purpose of the study is to examine the different therapeutic strategies for the management of patients with major depressive disorder (MDD) and suboptimal response to antidepressant drugs in primary care
It is challenging for depressed adolescents and their families to access specialized mental health services. A viable option is delivering treatment in the primary care clinic (PCC) setting; however, few effective models are currently available. The overall aim of this study is to assess in the pediatric PCC, the preliminary acceptability and feasibility of a novel collaborative stepped care model of treatment for depressed adolescents.
