Depression is a leading cause of disability worldwide, affecting nearly 16% of the general population. Its physiopathology remains unclear. Based on gene-environment studies and epigenetic studies, a main hypothesis proposed that the major depressive episode (MDE) results from the convergence of multiple factors including biological factors such as multi-genic vulnerability, hormonal and immunological variations as well as environmental factors. As a consequence, mRNA could define a biological signature of the MDE.
The purpose of this study is to assess the tolerability, safety, and efficacy of brexpiprazole (2.0 mg/day) as adjunctive therapy in adult subjects with a diagnosis of MDD with and without anxious distress
Examine the safety of long term repeat exposure to GLYX-13 in subjects who participated in GLYX13-C-202.
This multi-centre study will follow a randomised, double-blind, parallel-group, active-controlled design and will evaluate the efficacy, safety and tolerability of bupropion extended-release (XL) (300 mg/day) compared with escitalopram (10-20 mg/day) in outpatients and inpatients with major depressive disorder (MDD). The total duration of the study will be 11 weeks consisting of three phases. The screening phase (phase I) will be lasting for 0-14 days, subjects will be randomised to bupropion XL or escitalopram in a 1:1 ratio for acute phase treatment phase (phase II) for 8 weeks. There are 3 dose levels during this acute treatment phase. The 3-dose level plan is designed to ensure each drug is titrated according to the prescribing information and to reach an optimal clinical dose. Finally patients will enter the taper phase (phase III) for up to 1 week to assess and reduce the possible withdrawal symptoms. In China almost all existing antidepressants are available on the market, but bupropion XL has not yet been approved. This Phase III clinical trial will be used for the purpose of registering bupropion XL in China.
The purpose of this study is to determine whether Orcinoside Capsule in different doses are effective in the treatment of Depression. And to explore the preliminary information of safety and efficacy of Orcinoside Capsule in the Chinese Patients with Depression.
In recent years, measurement-based care (MBC) has been gaining more attention in the treatment of depression because it allows psychiatrists to individualize treatment decisions for each patient based on the change of psychopathology and tolerance toward antidepressants. Several studies, such as the Sequenced Treatment Alternatives to Relieve Depression (STAR*D) trial using MBC, found that MBC-informed sequential algorithms can be successfully integrated into clinical practice and improve patients' outcomes However, despite a strong theoretical rationale for MBC and data supporting the ability to implement MBC in clinical practice settings, there is currently no randomized controlled trial in MDD patients comparing MBC with usual/standard care. The investigators compare MBC with clinician's treatment decisions, standardizing care to two commonly prescribed antidepressants. Therefore, the aim of this study is to determine the effects of MBC in patients with MDD compared to standard treatment (ST). The research hypothesis is that compared to ST, the estimated time to response and to remission would be significantly shorter in the MBC group without increased dropout rates and side effect burden.
Many patients report residual depressive symptoms despite seemingly successful treatment. With the investigators' previous funding, we developed - Mindful Mood Balance - an online treatment that targets RDS by teaching specific emotion regulation and depression self-management skills that are entirely compatible with antidepressant treatment. The investigators now propose a controlled study to determine whether MMB is more effective than usual care at reducing RDS and other key outcomes. If successful, MMB's online delivery format would provide high fidelity and low-cost empirically supported management of residual symptoms, leading to more robust remission, improved functioning and sustained recovery from MDD over time.
Patients with severe mental illness (SMI) die younger than persons in the general population. Much of the excess mortality for SMI patients is attributable to cardiovascular disease, and is exacerbated by treatment with second-generation antipsychotics (2GAs). Although the cardiovascular risks are well-known, and safe, efficacious therapy exists, few SMI patients receive cardiovascular prevention drugs. Care delivery fragmentation and poor patient adherence are central problems to reducing cardiovascular risks for patients with SMI. To address these problems, we propose to conduct a multi-site, open-label, randomized controlled trial comparing an initial treatment strategy of free, fixed-doses of two generic, cardiovascular prevention drugs (statins and angiotensin drugs) delivered within mental health clinics versus usual treatment. The study will include adult patients (18+ years old) with schizophrenia, schizoaffective disorder, bipolar disorder, major depressive disorder, or psychosis not otherwise specified (NOS) who have received 2GAs treatment within the past six months from within four mental health clinics in the Boston area. We have three aims: 1) to compare the proportions of subjects in each arm who are receiving cardiovascular drug treatment and are adherent to therapy during 12-months of follow-up; 2) to compare changes in composite (e.g., Framingham scores) and individual (e.g., lipid levels) cardiovascular risk factor levels using an intent-to-treat (ITT) approach; and 3) to compare risk factor levels, accounting for variation in adherence over time, using causal inference techniques to estimate the per-protocol effect of the intervention. Our three aims examine whether this low cost, streamlined treatment strategy increases the numbers of subjects receiving cardiovascular prevention therapy and improves cardiovascular risk levels. We will follow subjects for 12 months, and collect interview and biometric data at baseline and over the following 12 months. Subjects will have the option to continue for another 12 months, during which we will continue to collect interview and biometric data, but will not prescribe cardiovascular medications. This population-based initial treatment strategy could be an effective and efficient approach for overcoming traditional barriers to cardiovascular disease prevention within the SMI population. Findings from this study will inform efforts to improve care and outcomes, and to enhance survival for patients with severe mental illness.
Mirtazapine is a non-SSRI (selective serotonin reuptake inhibitor) medication with a unique structure and mechanism of action. Recent study results suggest that mirtazapine may be more effective and faster acting than other antidepressants. Levels of alcohol use have been shown to be associated with levels of depressive symptoms among comorbid populations. Our own recent open label pilot study suggested robust within-group efficacy for mirtazapine for decreasing both the drinking and the depressive symptoms of persons with co-occurring alcohol dependence/major depressive disorder (AD/MDD). However, no placebo control group was employed in that study, so between-group efficacy versus placebo could not be assessed. The current grant submission proposes to conduct a first double-blind, placebo-controlled study to evaluate the efficacy of mirtazapine versus placebo for decreasing the alcohol use and depressive symptoms of persons with comorbid AD/MDD. If the results of this proposed double-blind pilot trial are promising, then the effect sizes found in this proposed study will be used to help design an adequately-powered R01 treatment trial to definitively test the efficacy of mirtazapine in this comorbid population.
