Active clinical trials for "Depressive Disorder, Major"

This is a one-armed observational study and feasibility trial of a remote electronically-delivered integrated care pathway for the treatment of adolescents. Eligible participants are between the ages of 13 and 18, inclusive, who have a primary diagnosis of major depressive disorder. Outcomes of interest are recruitment rates and participation in pathway components, including: appointments, measure-completion and use of electronically-delivered cognitive behavioural therapy.

The purpose of this study is to evaluate the efficacy and safety of Ammoxetine hydrochloride enteric-coated tablets in subjects with depression.

The goal of this observational study is to demonstrate effectiveness in the treatment of Major Depressive Disorder The primary objective is to assess the effectiveness in the treatment of Major Depressive Disorder using the CGI-I at the end of the treatment Participants will receive 10 treatments per day for 5 days (M-F) of SAINT®

Despite its successful use for more than 80 years, the mechanisms of action of electroconvulsive therapy (ECT) are still not fully understood. ECT has been shown to be accompanied by changes in regional brain volumes and connectivity measures, as well as biochemical alterations. However, how these changes relate to ECT response remains to be further elucidated; up to now, there are no objective markers for the targeted use of ECT in clinical practice. Methods: Study design: longitudinal mono-centre study with duration of 36 months. Subjects: 30 depressed patients (aged 18-65 years) eligible for ECT. Measurements: subjects will undergo 2 3-Tesla MRI scans (one before and one after a course of ECT), including structural MRI, resting-state functional MRI, task-based functional MRI and MR spectroscopy. Blood, CSF sampling and clinical assessments will be performed once before and once after the ECT course. ECT: Each patient will be treated in a min. of 8 bitemporal ECT sessions (~4 weeks). Data analysis: Longitudinal changes in brain imaging parameters and laboratory measures (before/after ECT) will be assessed using repeated-measures analysis of covariance. Machine learning with random forests will be employed to identify a pattern of pretreatment imaging, biochemical (serum and CSF) and clinical parameters that are best qualified to predict response to ECT as defined by a reduction of ≥50% of baseline HAMD17. Hypotheses: 1. ECT will be accompanied by changes in brain morphology, functional connectivity, neuronal activation in response to cognitive and reward-related stimuli and neurochemical signals in the brain. 2. ECT leads to changes in blood- and CSF-based markers of neuronal plasticity, neurodegeneration and inflammation, as well as genetic/epigenetic markers. 3. Predictive markers of ECT response can be established based on the relationships between imaging, neurochemical and clinical markers and treatment response. Innovation: This study would be the first to combine multimodal MRI measures with the assessment of biomarkers in the CSF in the context of ECT. The implementation of the proposed trial represents an important step towards a better understanding of the powerful antidepressant properties of ECT. By relating treatment effects and potentially underlying biological mechanisms on numerous complementary levels, the study might help to identify biomarkers that distinguish patients who are likely to benefit from ECT from non-responders. Ultimately, results of the study might be useful in order to establish an individualized medical indication for ECT.

The aim of this project is to investigate the multimodal magnetic resonance brain imaging changes in adolescents with major depressive disorder (MDD) before and after electroconvulsive therapy. Development of a predictive model for the efficacy of electroconvulsive therapy in adolescent MDD.

There are many common pharmacological treatments for major depression disorder (MDD), however the efficacy of these drugs often fails in severe cases. Intravenous (IV) administered ketamine may offer the potential for remission of the symptoms in patients with MDD; however it has not yet been approved by FDA for this purpose. This study will make use of an electroencephalography (EEG) machine to measure the brain's activity and response while the IV ketamine is being delivered. The objective of this study is to characterize the change in EEG response of patients with MDD, during and 4 weeks after a course of IV ketamine infusions.

Major depressive disorder (MDD) is a common mental disorder that affects patients' physical health and quality of life. Although traditional acupuncture therapy has certain advantages in improving MDD, there are still some limitations, such as being time-consuming and some people having a fear of acupuncture. Therefore, intradermal needle therapy will be chosen in the treatment of MDD in this study, which is more convenient, shallow needling, and gentle than traditional acupuncture therapy. The study is designed to investigate the therapeutic effect and safety of intradermal needles for MDD.

One in five people will present a major depressive episode (MDE) in their lifetime. While antidepressants (ADs) are currently the standard treatment for MDE, the first AD prescribed is effective in less than 40% of patients and a complete clinical response is only observed after several weeks. Identifying early biomarkers of the response to treatment with an AD could allow the clinician to rapidly identify patients in whom treatment will not be effective and therefore modify patient care. We have recently shown that the messenger RNA (mRNA) of two proteins, ELK1 and GPR56, were present in different amounts in the blood cells of "responder" compared to those of "non-respondent" patients. In this context, our main objective will be to determine whether ELK1 and GPR56 mRNAs, are very early biomarkers of the response to AD, i.e., biomarkers whose variation precedes the clinical response by several weeks. Secondary objectives will be to identify early phase changes in neurophysiological measures, cognitive and behavioral tasks, as well as levels of blood coding and non-coding RNAs, serum cytokine, mitochondrial and metabolic markers, neuroimaging markers as biomarkers of differential treatment outcomes to antidepressant treatment. Patients will be treated with SERTRALINE or FLUOXETINE or DULOXETINE or MAPROTILINE (in monotherapy) with or without adjunct benzodiazepine. Patients are identified as responders or non-responders based on their clinical assessment at 8 weeks after treatment onset. In addition, a second stage will collect data to address another important issue for the management of patients with a MDE: to discriminate those with a major depressive disorder (MDD) from those with a bipolar disorder (BD). BD diagnosis is one of the most common reasons of failure to response to ADs. Therefore, one of our secondary objectives will be to identify biomarkers to differentiate between these two categories of patients. To do this, we will follow patients for a period of 24 months to identify those who will present during this follow-up the diagnostic criteria of bipolarity.

Deficits in motivation and pleasure are common in depression, and thought to be caused by alterations in the ways in which the brain anticipates, evaluates, and adaptively uses reward-related information. However, reward processing is a complex, multi-circuit phenomenon, and the precise neural mechanisms that contribute to the absence or reduction of pleasure and motivation are not well understood. Variation in the clinical presentation of depression has long been a rule rather than an exception, including individual variation in symptoms, severity, and treatment response. This heterogeneity complicates understanding of depression and thwarts progress toward disease classification and treatment planning. Discovery of depression-specific biomarkers that account for neurobiological variation that presumably underlies distinct clinical manifestations is critical to this larger effort.
