Active clinical trials for "Depressive Disorder, Major"

Antidepressants is the primary treatment for depression, but only less than 50% of the patients get clinical remission. There is no objective markers to select antidepressants for clinical treatment . Clinical choose usually use experience and waste a lot of time, even the patients cannot be treated timely and effectively. The investigators found that the later antidepressant effect for 8 weeks is related with early brain functional response. Present prospectively drug treatment and follow-up study intends to adopt pharmacological imaging research methods to detect the brain function or structure change of three different mechanisms of antidepressant drugs, selective serotonin reuptake inhibitors (SSRIs, escitalopram), serotonin and norepinephrine reuptake inhibitors (SNRIs, duloxetine), norepinephrine and dopamine reuptake inhibitors (NDRIs, bupropion) in depression patients. Brain functional or structural magnetic resonance imaging data were collected at baseline, 1 days, 14 days and 12 weeks after treatment. The investigators want to observe the changes of brain functional networks and structure at different time points, acute and chronic treatment induced during drug treatment. Combined with the blood concentration detection, symptom change, cognitive function tests, the investigators also hope to determine the different mechanisms of drug efficacy of antidepressants with different mechanisms. The second aim is to explore different mechanisms of brain function for effective or ineffective drug response. The results of the study will help to further explain the mechanism of different antidepressants, to facilitate the development of early indicators for drug efficacy and individual treatment decision.

The main objective of this research project is to implement and evaluate the clinical effectiveness and cost-effectiveness of a Blended Cognitive-Behavioral Therapy (bCBT) in routine practice, comparing it with Treatment as Usual (TAU). This research project includes a pilot study and a randomized clinical trial (RCT). The pilot study main objective is to adapt the bCBT based on Moodbuster, an internet-based treatment platform developed by the ICT4Depression Consortium (INESC-TEC, Vrije Universiteit and University of Limerick), to the Portuguese population. More specifically, this pilot study intends: (1) to detect problems and refine procedures, establishing a definitive Portuguese version of the blended treatment; (2) to assess clinical effectiveness (non-controlled), estimating effect sizes at the end of the treatment and follow-up; (3) to assess patients' satisfaction and personal views concerning their process of change; (4) to develop dynamic models of the individual trajectories during treatment based on Ecological Momentary Assessments. The pilot study will involve the participation of psychologists trained in bCBT and 20 participants diagnosed with Major Depression and willing to use the Moodbuster system. The RCT is composed by two arms (an experimental condition and a control condition) and it will be implemented in routine practice. In the experimental condition, the patients diagnosed with Major Depression will receive a treatment that integrates face-to-face cognitive-behavioral sessions with online sessions available through Moodbuster system (bCBT). In the control condition, patients diagnosed with Major Depression will receive TAU that consists in routine care that patients receive in primary care. The RCT will involve the participation of family doctors and psychologists working in routine practice. One-hundred patients will be recruited and randomized in the two conditions: 50 patients for bCBT condition and 50 patients for TAU condition. The main objectives are: (1) to assess the clinical effectiveness of bCBT and compare it with TAU in routine practice; (2) to estimate and compare cost-effectiveness of both treatments; (3) to assess patients' and clinicians' satisfaction with the bCBT and TAU; (4) to refine the previous models of individual trajectories and to assess differential effects on different patient clusters; (5) to establish guidelines for using bCBT within Portuguese routine practice services.

This study investigates the brain-based biomarkers of treatment response to accelerated theta burst stimulation (aTBS) in patients with Major Depressive Disorder resistant to pharmacological treatment(MDD) in an open label design.

Residual Symptoms of Depression (SRD) are those symptoms that persist despite remission of MDD. They are characterized by a high incidence (approx. 90% of patients in remission) at the psychiatric clinic, have become a growing problem. Its presence is associated with a high probability of relapse / recurrence and disability, as determined by decreased performance and low quality of life. Their neglect has generated an increase in clinical and socioeconomic costs, alerting the need for research to provide treatment strategies. The application of different types of psychotherapy has been successful in abating SRD. The present study aims to evaluate the clinical changes related to the application of music therapy as a treatment of SRD, through a randomized controlled trial with two treatment arms trial. Music Therapy (MT) is a psychotherapy provided by specialized health professionals, and is defined as the clinical use of musical evidence-based interventions within a therapeutic relationship. MT treatment group will design an application schema of 8 sessions (2 hrs. Each) over a period of two months (one session per week). The control group will receive the Usual Treatment (TU) which corresponds to the usual clinical psychiatric treatment by the physician in the INPRF, with the same duration. The evaluation will be conducted with clinimetric testing at baseline, at the end of the track and after three months of treatment. This study seeks to identify the presence of SRD in a Mexican sample and explore a treatment designed for that purpose, also, show that the MT is a cost-effective implementation can become a new clinical option to extend the possibilities of assistance and deepen the investigation of this problem.

An open label study to assess the safety, tolerability, and effects of intranasal Ketamine in combination with rTMS for patients with treatment-resistant major depressive disorder (TRD). Patients will be given a dose of ketamine followed by 6 weeks of rTMS treatment.

The teaching platform of the TCM daycare clinics for depression patients will provide a good clinical training environment for the trainees. They can learn how to take care of depression patients by the lectures and the clinical practice experiences in the daycare clinics. They can also learn a holistic approach, a patient-centered healthcare service. This teaching model will strengthen the clinical training of TCM and enhance the international competitiveness of TCM doctors.

This is a single-center, double blind, randomized, placebo-controlled, parallel group study of bear bile pill, as add-on therapy in MDD patients conducted in Shang Hai Mental Health Center. The purpose of this study is to determine the efficacy and safety of bear bile pill in reducing symptoms of depression in Major Depressive Disorder (MDD)patients with inadequate response to current antidepressant therapy. Following a screening period, subjects who meet the entry criteria will be randomized to treated with either placebo or 450mg bear bile pill three times daily for 8 weeks.

The purpose of this study is to assess the prevalence of veterans with major depressive disorder (MDD) who are being treated with a medication that has current Clinical Pharmacogenetics Implementation Consortium (CPIC) or Pharmacogenomics Knowledgebase (PharmGKB) actionable recommendations that have a pharmacogenomic variation that impacts the safety or efficacy of the subject medication.

Inflammation that is mediated by microglia activation plays an important role in the pathogenesis of depression. Microglia activation can lead to an increase in the levels of proinflammatory cytokines, including TNF-α, which leads to neuronal apoptosis in the specific neural circuits of some brain regions, abnormal cognition, and treatment-resistant depression (TRD). Protein kinase C (PKC) is a key regulator of the microglia activation process. The investigators assume that the abnormality in PKC might be the serum biomarkers of depression.

The lifetime prevalence of major depressive disorder (MDD) is 10%~20%. Worldwide, nearly 340 million individuals have suffered the torture of depression. World Health Organization has reported that MDD would become the most serious global burden of disease and eventually turn into a public health problem in 2030. Varied clinical symptoms, inappropriate treatment, unclear pathogenesis, and lack of recurrent risk early-warning predictors cause a series of clinical problems, such as low diagnostic rate, low effective treatment rate, and high recurrent rate. Hence, this study aims to search multidimensional markers for early diagnosis of MDD, to establish optimized personalized therapy, and to explore sensitive recurrence predictors. Based on the criteria of the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), MDD is subdivided into eight different clinical specifiers, one of which the incident rate of MDD with atypical features reaches 30%~38%. However, there is still a lack of meta-evidence for the clinical treatment strategy in MDD with atypical features. And 45.4 percentage of MDD with atypical features convert to bipolar disorder. Therefore, this study will focus on three issues about what's the objective endophenotype in MDD with atypical features, how to select appropriate personalized treatment for MDD with atypical features, what's the predictive biomarker of conversion to bipolar disorder. Based on the investigators' previous findings, this study will investigate adult depression at a cross-sectional study and a prospective cohort study. Multivariate informatics analysis was performed from three research dimensions (cognitive neuropsychology, metabonomics, and multimodal neuroimaging), including atypical features, "cold/hot" cognition assessment, KP (kynurenine pathway) metabolomics and inflammatory factors, multimodal MRI robust property. Referring guidelines for the diagnosis and treatment of depression and evidence-based medicine evidence, MDD with atypical features are divided into f groups (antidepressants, antidepressants+mood stabilizers, mood stabilizers, treat as usual). Then, the investigators perform follow-up to verify optimized treatment strategies and to explore risk factors of conversion from MDD with atypical features to bipolar disorder. Furthermore, this study performs correlation analysis to analyze cross-omics data, weight coefficient analysis to analyze multidimensional indexes, clustering analysis to analyze multivariate bio-information data, and artificial intelligence technologies (such as pattern recognition, and machine learning) to realize the transformation from medical data to practical transformation. Eventually, this study builds three specific models (the multidimensional early diagnosis models for MDD with atypical features, the optimized personalized therapy model, and the recurrence and conversion risk early-warning model), which form the integrated intelligent platform for multidimensional diagnosis, personalized treatment, recovery management of MDD with atypical features.
