The goal of this study is to learn whether 5 days of accelerated intermittent theta burst stimulation (iTBS), a rapid form of transcranial magnetic stimulation (TMS), which is a non-invasive procedure that uses magnetic fields to stimulate brain activity, works to treat depression in adults. The main questions it aims to answer are: * Does accelerated iTBS reduce depressive symptoms compared to sham (placebo) stimulation? * Are there measurable brain, biological, and digitally measured emotion changes associated with treatment response? Participants will: * Be randomly assigned to receive either active iTBS or sham stimulation * Receive 10 stimulation sessions per day for 5 consecutive days (total of 50 sessions) * Complete MRI brain scans and EEG recordings before and after treatment * Provide blood and saliva samples to measure biological markers * Complete depression rating scales and questionnaires at baseline, during treatment, and at follow-up visits * Use a secure mobile app to record brief facial and vocal samples during the 5-day treatment and at follow-up visits * Return for follow-up visits at 1 week and at 1, 3, 6, and 12 months after treatment

Repetitive Transcranial Magnetic Stimulation (rTMS) of the motor cortex is a recognized analgesic technique for the treatment of fibromyalgia pain, which represents a largely unmet medical need. However, the effectiveness of motor cortex rTMS is inconsistent, being observed in only about 40% of patients and not always long-lasting. It has been previously shown that predictive factors for a lack of response to motor cortex rTMS include the presence of depressive symptoms, and that prefrontal cortex rTMS is not effective for pain, even though this treatment has proven efficacy in major depressive disorder. The hypothesis is that targeting both the motor and prefrontal cortices with rTMS will yield a particularly beneficial effect in fibromyalgia patients presenting with comorbid depressive symptoms. Given the absence of established biomarkers for predicting rTMS response, an additional aim will be to develop reliable indicators of rTMS efficacy, based on clinical phenotype and measurements of oscillatory patterns assessed by electroencephalogram (EEG) recordings.
NCT06951542
The overall aim of this study is to assess the acceptability, feasibility, fidelity, and effectiveness of a depression treatment intervention augmented with counseling to address stigma. Using a multiple-baseline design, 200 depressed adults living with HIV will be enrolled in the trial. Participant surveys and abstracted clinical data related to HIV and depression care will assess the effectiveness of the intervention.
NCT07620288
The proposed project will investigate the neurobiological mechanisms of accelerated intermittent Theta Burst Stimulation (iTBS) in major depressive disorder (MDD) using an advanced multimodal imaging approach. This single-arm, within-subject study will deliver one week of accelerated iTBS and use pre-/post-treatment PET/MRI to quantify changes in synaptic density, functional connectivity, and microstructural integrity. We will combine \[¹⁸F\]SynVesT-1 PET with functional, neurochemical and anatomical MRI, such as resting-state fMRI, magnetic resonance spectroscopy (MRS) and neurite orientation dispersion and density imaging (NODDI), to capture treatment-related plasticity. This integrated design will link molecular and network-level mechanisms to clinical improvement, providing an unprecedented mechanistic map of how accelerated iTBS restores brain function in depression.
NCT07022405
This research study aims to understand how people with depression respond to the medication pramipexole and to determine whether clinical response differs depending on the function of specific circuits in the brain. The investigators hope to learn which circuits are involved in depression and how these circuits interact with pramipexole to affect mood, behavior, and cognition. Eligible participants will undergo an 8-week treatment course of pramipexole followed by a 2-week down taper and follow up. The ultimate goal is to offer people experiencing depression a medication that is alternative to ones that may not have worked in the past and to apply the knowledge the investigators gain from investigating the brain circuits involved in depression to help personalize treatment. The investigators invite anyone who has recently experienced symptoms of depression to participate. A prior diagnosis of depression is not required.
NCT07553130
Major depressive disorder (MDD) and anxiety are increasingly prevalent among university student populations, yet early detection remains reliant on psychometric instruments tied to diagnostic criteria (e.g., PHQ-9, GAD). Emerging evidence suggests that depression affects both the acoustic properties and content of speech, making speech analysis a promising candidate as a digital biomarker for early screening. This study evaluates the validity of acceXible, a speech-based machine learning platform, for the detection and monitoring of depression and anxiety in the student population of the Benemérita Universidad Autónoma de Puebla (BUAP), Mexico. AcceXible captures spontaneous speech through open-ended interview tasks and applies automated acoustic and linguistic analysis. The primary objective is to evaluate the validity of the acceXible spontaneous speech analysis system for depression and anxiety screening, assessed against the PHQ and GAD scales as reference standards. Secondary objectives include examining associations between speech-derived variables and other study measures, evaluating participant engagement with digital mental health resources, assessing user satisfaction with the platform, and analyzing longitudinal changes in scores across follow-up assessments.
NCT07480486
The purpose of this clinical trial is to evaluate whether using pharmacogenetic testing to guide antidepressant treatment can improve outcomes in adults with major depressive disorder in Morocco. Depression is a common mental health condition, and finding the most effective antidepressant for a patient can take time. Some individuals do not respond well to the first medication prescribed or may experience side effects. Pharmacogenetic testing examines genetic variations that can influence how a person processes certain medications. Information about genes involved in drug metabolism, such as CYP2D6 and CYP2C19, may help clinicians choose antidepressants and adjust doses more appropriately for each patient. The main question this study aims to answer is whether treatment guided by pharmacogenetic test results leads to higher remission rates of depressive symptoms compared with usual clinical care. In this study, participants diagnosed with major depressive disorder will be randomly assigned to one of two groups. In the pharmacogenetic-guided group, clinicians will receive the patient's genetic test results and may use this information to guide antidepressant selection and dosing. In the usual care group, antidepressant treatment will be prescribed according to standard clinical practice without access to pharmacogenetic information. Participants will receive antidepressant treatment and will be followed for 12 weeks. During this period, depressive symptoms will be evaluated using standardized clinical questionnaires, including the Patient Health Questionnaire (PHQ-9). Information on treatment response, medication tolerance, and adverse effects will also be collected. This study aims to provide evidence on the potential role of pharmacogenetic-guided treatment in improving depression management and to support the development of personalized medicine approaches in psychiatric care in Morocco.
NCT07484789
Major depression is a mental illness that seriously threatens public health, leading to disability, reduced quality of life, economic burden, and premature death. It is estimated that 18.4% of the world's population lived with depression between 2005 and 2015, and it is projected to be a leading cause of global disease burden by 2030. Major depressive disorder manifests with symptoms such as decreased interest and desire, a depressed mood, increased or decreased sleep and appetite, feelings of worthlessness and guilt, decreased energy, suicidal thoughts and attempts, leading to significant impairment in functioning. Choosing the appropriate treatment for depression and taking measures to improve the individual's functionality quickly, shorten hospital stays, and reduce the number of hospitalizations are crucial. In addition to pharmacological treatment, clinical guidelines recommend the combined use of pharmacological and psychosocial interventions in the treatment of depression. The mindfulness-based cognitive therapy, which forms the basis of the psychoeducation planned for this study, was developed as an 8-week group approach. Theoretical studies examining emotion regulation mechanisms have indicated that mindful awareness is a fundamental mechanism for emotion regulation. The literature suggests a negative correlation between mindful awareness and the severity of depressive symptoms and difficulty in emotion regulation. Furthermore, despite numerous descriptive, correlational, and experimental studies on major depression, no studies have been found demonstrating the effect of mindful awareness-based psychoeducation on emotion regulation difficulties, distress tolerance, and symptom severity in patients diagnosed with major depression. This study, therefore, differs from existing research and will make a significant contribution to the literature.

The purpose of this study is to determine the efficacy, safety and tolerability of CYB003 compared to matching placebo as adjunctive treatment in patients with MDD.
NCT07478796
Depression in childhood and adolescence is a serious and increasing public-health problem associated with profound short- and long-term consequences, including impaired social and educational functioning, increased risk of somatic illness and substance use, and elevated mortality from suicide. Up to half of depressive disorders beginning in youth persist into adulthood, and the COVID-19 pandemic, with its attendant social isolation, has further increased the incidence of clinically significant depressive illness in children and young adults. Despite the high burden of disease, pharmacotherapeutic guidance for pediatric depression remains limited. Selective serotonin reuptake inhibitors (SSRIs) are first-line agents, yet dosing recommendations for youth do not adequately account for major sources of variability such as developmental pharmacokinetics, body size, age, comorbid diagnoses, and pharmacogenetic differences. Fluoxetine is commonly recommended in pediatric populations largely for historical reasons, while newer SSRIs such as escitalopram and sertraline are increasingly prescribed off-label without robust comparative evidence. This randomized clinical trial evaluates therapeutic drug monitoring (TDM)-guided treatment with fluoxetine, sertraline, or escitalopram in children and adults diagnosed with Major Depressive Disorder. TDM procedures will be implemented across all randomized arms to capture drug exposure and enable dose adjustments according to predefined safety and efficacy criteria. Treatments will be initiated at the lower end of recommended pediatric doses and titrated if prespecified clinical nonresponse or tolerability thresholds are met, allowing evaluation of dose-response dynamics while prioritizing patient safety. The study combines prospective, randomized comparative effectiveness methodology with intensive pharmacokinetic/pharmacodynamic (PK/PD) assessment. Repeated plasma concentration measurements will be collected at multiple timepoints to characterize within- and between-patient PK variability for each SSRI. Standardized clinical instruments will be used longitudinally to assess depressive symptom severity, response and remission rates, time to onset of therapeutic effect, adverse events (including early activation and worsening of suicidal ideation), treatment adherence, and functional outcomes (academic performance, social functioning, and quality of life). Pharmacogenetic testing will be performed to evaluate the contribution of genetic variants (including but not limited to CYP enzymes, serotonin transporter and MAO-A related polymorphisms) to PK parameters and clinical response. Integrated population PK and PK/PD modeling will (1) quantify concentration-effect and concentration-adverse-effect relationships over time, (2) identify demographic, clinical and genetic moderators of exposure and response, (3) evaluate nonlinearity in PK (e.g., dose-dependent absorption or clearance patterns), and (4) derive evidence-based therapeutic concentration ranges and individualized dosing algorithms for pediatric practice. Secondary objectives include head-to-head comparison of efficacy, tolerability, time to response, and persistence on treatment between the three SSRIs, as well as exploratory analyses of diagnostic subtypes and comorbidities that may influence outcomes. By filling critical gaps in controlled PK/PD data for the most commonly prescribed SSRIs in youth, this trial aims to move beyond meta-analytic inference toward actionable, individualized dosing recommendations. The expected outcomes are earlier identification of atypical pharmacokinetics, safer and more effective dose optimization, reduced adverse events and early discontinuation, shortened time to symptomatic improvement, and ultimately improved functional recovery and quality of life for children and young adults with depression. The study's translational PK/PD outputs will inform clinical TDM protocols, pediatric dosing guidelines, and future precision-medicine strategies in adolescent psychopharmacology.
NCT07474974
This research explores the potential of retinal ganglion cells (RGCs), particularly intrinsically photosensitive RGCs (ipRGCs), as biomarkers for predicting response to transcranial magnetic stimulation (TMS) in treatment-resistant depression (TRD). We also aim to assess the impact of TMS treatment on RGCs and ipRGCs in TRD patients, investigating associations with clinical improvements and cognitive status. A clinical trial involving 44 patients with treatment-resistant depression (TRD) will be conducted. All participants will receive rTMS targeting the dorsolateral prefrontal cortex (DLPFC). Data will be collected pre- and post-intervention, as well as at a 2-month follow-up, using multiple outcome measures, including the post-illumination pupil response (PIPR). The project seeks to confirm the effectiveness of TMS and the potential of RGCs/ipRGCs as predictors of treatment response, thereby facilitating the development of personalized treatment strategies for TRD patients undergoing rTMS therapy.
NCT07452900
This study aims to evaluate outcomes from the Shields \& Stripes (S\&S) program - a 12-week, multidisciplinary wellness intervention designed for veterans and first responders. The S\&S program integrates occupational therapy (OT), mental health (MH), physical therapy (PT), and registered dietitian (RD) services to promote recovery, resilience, and performance in individuals who have experienced cumulative stress, trauma exposure, or occupational burnout. This research will use a retrospective mixed-methods observational design to analyze data collected from previous S\&S participants who consent to research use of their de-identified information. No intervention or treatment changes will occur as part of this study. Quantitative data will include biometric information (e.g., sleep, activity, and heart rate variability via Oura Ring), standardized self-report measures (GAD-7, PHQ-9, PCL-5, RAND-36, PSQI, ISI), satisfaction surveys, and laboratory nutrition panels. Qualitative data will include semi-structured interviews with consenting participants and S\&S providers following program completion. The purpose of the study is to identify patterns of improvement in physical, psychological, and occupational functioning and to explore how integrated, team-based care supports holistic recovery. Findings may inform the development of future evidence-based wellness programs for military and first-responder populations. Participation involves minimal risk, and all data will be de-identified before analysis.
NCT07453420
The study protocol was submitted to ERA-NET NEURON for funding on 28/06/2023. Description of the Israeli responsibilities was extracted from the full submitted research protocol. The protocol includes two studies (CHS1 and CHS2). At the time of the study registration CHS1 was partially analyzed whereas CHS2 has not been initiated. See below the full description of the two studies' protocols. To explore the probability of mental illness (MI) onset or psychiatric relapse following infections, we will utilize two databases from the CHS registries from Israel (n=50,000, n=69,594). Participants with a high load of past infections (cohort 1, n=50,000) will be identified and matched in a 1:1 ratio to controls by age and sex. Probability of MI onset across a broad range of psychiatric disorders, including depression, bipolar disorder, anxiety and psychotic disorders will be explored. The probability of psychiatric relapse among individuals with pre-existing mental disorder following infection will be investigated in a cohort of 34,797 individuals with schizophrenia matched randomly to age and sex controls with no diagnosis of schizophrenia (n = 34,797) (cohort 2, total n=69,594, 5). Socio and sociodemographic factors which might serve as vulnerability or resilience factors will be assessed across both cohorts, and will include environmental factors such as socioeconomic status, familial status, healthcare utilization information and demographic factors. In addition, The CHS databases (n=50,000, n=69,594) will be utilized to study outcomes of infections in SMI. From the CHS databases in Israel, outcome of infections will be assessed in the two previously described cohorts. Severe outcomes will be defined as hospital admission \~two weeks after a diagnosis of an infection, among individuals with pre-existing anxiety, depression, bipolar diagnosis (n=50,000), and among patients with schizophrenia (n=69,594), as well as all-cause mortality. The following infections will be considered: Epstein Barr Virus, Cytomegalovirus, Toxoplasma Gondii, COVID-19, and Herpes viruses. Environmental protective and risk factors and their moderating role in the association between infection and outcome will include marital status, number of siblings, and sociodemographic factors. Vulnerability factors such as smoking, obesity, and comorbid physical illness will also be examined. The presence of pre-existing viral infections will be assessed as a potential vulnerability factor.

The goal of this study is to learn how psilocybin delivered with mindfulness-based therapy may help symptoms of posttraumatic stress disorder (PTSD). This is an assessor-blinded, randomized, controlled study in participants with PTSD. The study will investigate the changes in brain activity, connectivity, and microstructural neuroplasticity assessed using EEG/EMG and multimodal MRI measures after administration of one oral dose of psilocybin, accompanied either with standard "psychological support" only; or with standard support plus Mindfulness-based Cognitive Therapy (MBCT).
NCT07143838
The goal of this pilot study is to determine if non-invasive brain stimulation during sleep can increase deep sleep in adults with depression. It will also determine if increased deep sleep improves cognitive performance and mood ratings. Participants will be asked to wear a non-invasive device that records their brain activity and delivers transcranial electrical stimulation during sleep. Participants will also wear an actigraphy watch that measures activity levels throughout the study. In addition, participants will complete several cognitive assessments and mood and sleep questionnaires throughout the study.
NCT07422519
The primary aim of this study is to evaluate the efficacy and tolerability of a combined Virtual Reality (VR)-based mindfulness intervention and pharmacological treatment compared with pharmacological treatment alone in reducing depressive symptoms in patients with Treatment-Resistant Depression (TRD). Secondary questions this study aims to address include: 1. Does the combined intervention lead to changes in inflammatory blood parameters compared with pharmacological treatment alone? 2. Does the addition of a VR-based mindfulness intervention prolong remission of depressive symptoms six months after treatment completion? 3. Is the combined treatment with mindfulness and esketamine well-tolerated, and how does its adverse effect profile compare with esketamine treatment alone? 4. Is there an association between changes in mindfulness trait levels, assessed using the FFMQ-SF, and reductions in depressive symptom severity? Participants will be recruited from a Treatment-Resistant Depression Programme and randomly assigned to receive either VR-based mindfulness intervention in addition to treatment as usual or treatment as usual alone. The mindfulness intervention will last one month and include a total of 8 sessions. All participants will undergo comprehensive assessments at baseline and at predefined follow-up time points to evaluate clinical outcomes, inflammatory markers, tolerability, and remission duration.

The main outcomes will include changes in depressive symptoms and cannabis use, as well as usability ratings.
NCT07427277
Introduction Depression is one of the most prevalent mental health disorders globally, significantly impacting individuals' quality of life, academic performance, and overall functioning. According to the World Health Organization (WHO), depression affects more than 264 million people worldwide, and it is considered a leading cause of disability. Among young adults, particularly students, the condition is increasingly common and often underdiagnosed and undertreated (1). Medical students are at a disproportionately higher risk of depression compared to the general population due to the intense academic workload, pressure to perform, competitive environment, and exposure to human suffering during clinical training (2). A meta-analysis found that approximatel…

The MOP II study examines how to improve therapy for people struggling with a depressive disorder. Cognitive Behavioral Therapy (CBT) and Short-Term Psychodynamic Psychotherapy (STPP) are two evidence-based treatments for depression that are widely used. Meta-analyses indicate that CBT and STPP are one average equally effective and superior to no treatment. However, many patients do not respond sufficiently and relapse rates after acute phase treatment are high. Earlier research and theoretical insights suggest three promising strategies to enhance the effectiveness of psychotherapy. First, we want to examine whether increasing the frequency of the sessions will increase the effect of therapy. We want to compare once-weekly and twice-weekly sessions in both CBT and STPP to see whether more frequent sessions lead to better and more lasting reductions in depressive symptoms with the same total number of sessions. Second, the study aims to answer what works for whom in two different psychotherapeutic approaches. People with depression differ in personality, life experiences, relationship styles, and how they understand the causes of their depression. Previous findings suggest that patients do better when the therapy approach matches how they see their problems. The MOP II study wants to replicate this finding. Third, the study wants to examine how therapy leads to change. In CBT, improvement is thought to happen through changes in thinking patterns, such as fewer negative automatic thoughts and less rumination. In STPP, change is expected to come from better self-understanding, greater emotional awareness, and healthier ways of relating to others. Consequently, the goal of the MOP II study is to find out whether more frequent therapy, better matching of patients to treatment type, and a clearer understanding of how therapy works can lead to faster improvement of depressive symptoms.
