View clinical trials related to Major Depressive Disorder.
Filter by:Schizophrenia, bipolar and major depressive disorders collectively affect over 10 million people across the EU and are associated with annual healthcare and societal costs in excess of 100 billion Euros. When diagnosed with one of these disorders, patients are prescribed psychotropic medication such as antidepressants, mood stabilisers or antipsychotics. It is unknown whether this first-line treatment will be successful. After this first-line treatment fails, usually a second-line treatment is initiated, and when this is not successful either a third-line treatment is initiated. Third-line treatments are quite successful, especially when compared to second-line treatments. The research question is whether the third-line treatments (early-intensified treatments) would be more efficacious than the current second-line treatments (treatment as usual) for schizophrenia, bipolar and major depressive disorders. If this is indeed the case, this could lead to the prevention of unnecessary trials of ineffective treatments and adaptations of worldwide guidelines as well as a reduction of healthcare and societal costs.
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.
The POKAL-PSY project is a study that monitors participants for five years. The goal of the study is to identify distinguishable subtypes of depression on the basis of biomarkers and to gain insight into their prognostic significance.
Depression is a leading cause of disability worldwide and poses a large economic burden in the UK. There is evidence that exercise is beneficial in the management of depression and NICE now recommends group exercise programs as a treatment for people with mild and moderate-severe depression. Research shows that patients with severe depression are less likely to engage in exercise than patients with mild to moderate depression. There is little evidence, however, on the barriers and drivers to participation in such programs experienced by patients with depression; leading to uncertainty in the most effective way to implement these programs. We aim to analyse accounts of patients who have been referred to or participated in the Exercise Recovery Group (ERG), a group exercise program at the Nottingham Specialist Depression Service (NSDS). The NSDS is a tertiary unit where referred patients have suffered moderate-severe, persistent clinical depression. Eligible participants will be patients with persistent major depression who have agreed to referral to the ERG at the NSDS and who are able to provide informed consent. Participants will undergo a one-off 60 minute meeting via MS Teams, including an in-depth semi-structured interview on their experience as well as self-completion questionnaires assessing demographics, depression, anxiety and shame. Transcripts of the interviews will be subject to qualitative thematic analysis addressing questions on barriers and drivers of exercise treatment in depression; and the perceived impact of an exercise group on the individual participating. Themes will be developed to give an account of these questions, supported by anonymised quotes from the transcripts. The questionnaire data (on demographics, depression, anxiety, shame) will be used to characterise the group, in order to help assess directness of the evidence provided for other clinical populations; ultimately helping clinicians to implement exercise groups for depression that are acceptable for patients.
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.
Acupoints are the stimulus points and reactive points for acupuncture to treat the diseases. Therefore, this study is designed to detect the biological specificity of acupoints in healthy participants and major depressive disorder (MDD) participants by using multiple objective assessment tools. And then acupoints that are statistically different between the two groups will be defined as strong reaction points, and other acupoints without statistically different will be defined as weak response points. In addition, this clinical trial will be conducted to explore whether the efficacy of stimulating strong reaction acupoints is more effective than weak reaction points, thereby confirming the specificity of the acupoint.
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.
Major Depressive Disorder (MDD) has a high prevalence, is the leading cause of disability, and currently available interventions are associated with side effects and high treatment resistance. There is an urgent need for the development of novel interventions for MDD with alternate mechanisms of action. Temporal Interference (TI) stimulation is a newly emerging form of transcranial alternating current stimulation (tACS) that involves the application of two high-frequency currents at slightly different kHz frequencies. Since neurons, due to their intrinsic low-pass filtering, do not respond to high frequencies (i.e. > 100 Hz), TI relies on the 'beat' interaction leading to neuromodulation at any given location, resulting in a much smaller focus and allowing for better targeting. The subgenual cingulate cortex (SCC) appears to be critical in the pathophysiology of depression and treatment response, especially in treatment-resistant cases. Non-invasive treatments, however, are not able to accurately target SCC due to its deep location within the brain. In this trial, 30 participants meeting the diagnostic criteria for MDD will be randomized to receive 10 sessions of 130 Hz TI delivered daily for 30 minutes, or 10 sessions of sham stimulation. The investigators will collect metrics of SCC target engagement using the resting-state fMRI and EEG technologies, and determine feasibility, tolerability, safety, and therapeutic efficacy of TI stimulation in MDD. The results of this trial will inform the TI technology as a therapeutic tool for network-based psychiatric disorders, including MDD, and be vital for the design and development of a large-scale randomized-controlled trial.
The purpose of this study is to evaluate the feasibility of an evidence-based system to recommend core interventions, before the beginning of treatment, to psychotherapists treating low-income patients with depressive or anxiety disorders.
Several studies investigating acupuncture for major depressive disorder (MDD) have been carried out. However, investigators found the results were in high heterogeneity and poor methodological quality. Thus, investigators intend to provide high quality of the effectiveness and safety of acupuncture for MDD.
