Clinical trials

The goal of the Life Force study is to (1) evaluate the efficacy of targeted, skills-based training for enhancing mental toughness and mitigating harmful and high-risk behaviors in active-duty Soldiers, and (2) to determine who benefits the most from this type of training. Researchers will compare the training group to a control group. All participants will complete a baseline survey and two follow up surveys at 6 and 12 months post-baseline. The group assigned to the Life Force training condition will also complete a 5-session, group-based, skills training program.

This study evaluates the effectiveness of Pathfinding, a 6-month, remotely-delivered case management intervention designed to decrease suicidal behavior among active-duty Regular Army soldiers recently discharged from inpatient psychiatric treatment. Soldiers discharged from military treatment facilities across the U.S. will be identified and recruited to participate. Those who consent will be randomly assigned to receive either Treatment As Usual (TAU), which is the Army's standard post-discharge care, or TAU plus Pathfinding. Participants will complete a baseline assessment and follow-up assessments 6 months and 12 months later. The 6- and 12-month follow-up periods will also include examination of participants' electronic healthcare data and Army administrative data. The overall goals of the study are: (1) to evaluate whether Pathfinding decreases suicidal behaviors among soldiers transitioning from psychiatric hospitalization back to the community; and (2) to determine which discharged soldiers are most likely to benefit from the Pathfinding intervention versus TAU alone.

The goal of this observational study is to learn about the impact of low-level blast exposure in U.S. Special Operations Forces personnel. The main questions it aims to answer are: What advanced brain imaging changes are related to clinical presentation after low-level blast exposure? What are the relationships between low-level blast exposure and common groups of symptoms after concussion? Participants will: * Undergo advanced brain imaging * Answer questionnaires * Complete clinical tests * Provide blood, urine, and saliva samples * Wear blast sensors

The INSIGHT study is a multi-site clinical research program designed to examine how insomnia and symptoms of sympathetic hyperactivity impair sleep, cognition, and physiological restoration in warfighters, and to evaluate whether a wearable therapeutic device can improve these outcomes. Warfighters with a history of traumatic brain injury, post-traumatic stress disorder, or chronic operational stress commonly report disrupted sleep accompanied by manifestations of nocturnal sympathetic activation such as diaphoresis, palpitations, hyperarousal, and nightmares. These symptoms erode sleep quality, reduce cognitive performance, and undermine psychological resilience and operational readiness. Insomnia is two to three times more common in military populations than in civilians, and both TBI and PTSD independently elevate the risk for dysregulated autonomic tone. Excessive sympathetic activity during REM sleep disrupts the normally quiescent locus coeruleus state required for adaptive emotional processing and may contribute to the genesis of nightmares. Excessive sympathetic tone may also interfere with deep NREM-dependent glymphatic clearance, a recently discovered mechanism that supports cognitive restoration and metabolic waste removal. Yet, no study has comprehensively linked these physiological processes in warfighters or evaluated whether wearable-derived autonomic measures can meaningfully stratify insomnia phenotypes. The INSIGHT protocol addresses this gap through a two-phase design integrating multimodal biomarker collection, wearable technology validation, advanced imaging, and a randomized controlled intervention. Phase 1 enrolls 250 participants (50 healthy controls and 200 poor sleepers with or without PTSD and TBI) who undergo structured screening, cognitive testing, and detailed baseline assessments before completing a 2-week at-home data collection period. During this period, participants wear a suite of devices, including EEG headbands, ECG patches, PPG-based sensors, accelerometry rings, blood pressure devices, temperature sensors, and smartwatches, to capture autonomic activity, sleep architecture, cardiovascular and respiratory variability, movement, sudomotor activity, and circadian body temperature patterns. Ecological momentary assessments administered three times daily track fluctuations in sleep quality, mood, PTSD symptoms, and daytime functioning, while urine samples collected on the final three days allow for biochemical analysis of hormonal and sympathetic biomarkers. After the at-home period, all participants complete an overnight in-lab polysomnogram combined with fNIRS to measure sleep stages, autonomic dynamics, cerebral hemodynamics, and glymphatic signatures. A subset of participants also completes an optional overnight MRI with simultaneous EEG following controlled sleep deprivation, enabling state-of-the-art imaging of human glymphatic activity using the MAGNUS MRI platform. This optional visit provides unprecedented insight into how TBI, PTSD, and insomnia alter the physiology of sleep-dependent brain fluid dynamics. In Phase 2, all poor sleepers enter a double-blind, sham-controlled, 30-day randomized trial testing the therapeutic potential of the NightWare smartwatch. NightWare detects sympathetic surges during sleep through heart rate elevations and movement patterns and delivers brief haptic vibrations aimed at interrupting escalating autonomic arousal. Although originally cleared for nightmare treatment, its mechanism is well suited for SNH-related insomnia more broadly. Participants use the device daily while continuing EMA surveys, wearable monitoring, and cognitive assessments, generating rich physiological and behavioral data throughout the intervention. The primary goal is to determine whether reducing nocturnal sympathetic spikes leads to measurable improvements in sleep quality, autonomic stability, daytime functioning, and symptom burden. In parallel, Phase 2 data enable development of the Multi-Organ Autonomic Index of Sleep, an integrated biomarker model that combines neurological, cardiovascular, respiratory, and dermal signals to predict treatment response and classify insomnia subtypes. The INSIGHT study will produce the most comprehensive dataset to date linking autonomic physiology, glymphatic function, sleep architecture, wearable-derived biomarkers, cognition, and clinical outcomes in warfighters. By identifying physiological signatures of sympathetic hyperarousal and determining whether a non-pharmacological wearable intervention can meaningfully improve sleep, INSIGHT directly supports Department of Defense priorities to enhance readiness, resilience, and long-term neurological health in service members. Wearable tools capable of monitoring and improving sleep outside the laboratory have the potential to transform both clinical care and operational performance, offering scalable and accessible approaches to restoring sleep and optimizing recovery.

The overall purpose of this study is to compare changes in sleep outcomes in people with obstructive sleep apnea (OSA) depending on their participation in one of two behavioral interventions; both involve drinking water and breathing. A second purpose is to compare outcomes between people who have sustained a traumatic brain injury (TBI) and those with no history of TBI. The main questions it aims to answer are whether sleep quality improves after 3-months of high-resistance versus low-resistance exercises, and whether people have different outcomes depending on their history of TBI.

This project will evaluate the effectiveness of Level Up: Boost Your Life Skills ("Level Up"), a strengths based, military-specific life skills training program. The goal is to determine whether Level Up can decrease suicidal-related behaviors (SRBs) and other harmful behaviors, improve mental health, enhance job performance, and reduce early military separation. The Level Up program components will be made available to participants through an online platform or mobile app that can be downloaded onto their personal mobile devices. These training materials will help Soldiers learn and practice skills. The Level Up program will also involve personalized messages from a Level Up trainer and virtual booster sessions. Soldiers arriving at their first duty location will be randomized to receive either Level Up or a single session Army bystander intervention program. Participants will complete baseline and follow up surveys 1, 3, and 6 months post-baseline.

This cohort study aims to compare the efficacy of Xeomin injections for migraine management in patients with a history of Traumatic Brain Injury (TBI) versus those with a history of Anomalous Health Incidents (AHI). The study will be conducted at the National Intrepid Center of Excellence (NICOE) in Bethesda, MD. The primary objective is to determine if Xeomin injections result in different outcomes for migraine management between TBI and AHI patients. This is a combined retrospective and prospective cohort study design. Patients scheduled for Xeomin treatments will be categorized into TBI and AHI groups. For the prospective cohort, participants will complete a baseline questionnaire, receive their scheduled Xeomin treatment, and participate in follow-up interviews at 4-6 weeks and 10-12 weeks post-treatment. For the retrospective cohort, similar information will be acquired from existing records. Statistical analysis will compare migraine characteristics and treatment responses between the two groups. All data will be de-identified to protect patient privacy.

The long-term goal of this research is to improve military health and operational readiness among military service members with sleep disorders. The overall objective of the current study is to 1) determine the clinical effectiveness (non-inferiority) and cost-effectiveness of OSA telehealth care, including a human sleep navigator (vs private sector care), and 2) to perform a formative evaluation of the implementation of the OSA telehealth care intervention within the National Capitol Region (NCR) market. The central hypothesis is that OSA telehealth care including a human sleep navigator is clinically non-inferior to private sector care and also more cost-effective than private sector care. The investigators plan to achieve the objectives via these 3 Specific Aims: Specific Aim 1: To determine the clinical effectiveness (non-inferiority) of OSA telehealth care, relative to private sector care. Hypothesis 1a: Relative to private sector care, OSA telehealth care is non-inferior for achieving PAP adherence (primary endpoint). Hypothesis 1b: Relative to private sector care, OSA telehealth care is non-inferior for reducing OSA symptoms and for patient satisfaction (secondary endpoints). Specific Aim 2: To engage participants via qualitative focus groups and conduct a formative evaluation of the implementation of the OSA telehealth care intervention, using a standardized approach based on the Reach, Effectiveness, Adoption, Implementation, and Maintenance (RE-AIM) framework. Specific Aim 3: To perform a cost-effectiveness analysis of OSA telehealth care from the DHA perspective. Hypothesis 3: Relative to private sector care, OSA telehealth care is more cost-effective.

This is a prospective randomized controlled trial comparing two ways of delivering Motion-assisted, Multi-modular Memory Desensitization and Reconsolidation (3MDR) therapy for posttraumatic stress disorder (PTSD). The study seeks 60 volunteers who have PTSD and are eligible for care in the Department of Defense healthcare system. There will be 10-14 therapy sessions that are 60-90 minutes long, about once a week, and symptoms will be assessed before and after the therapy as well as 3 and 6 months after completing therapy. 3MDR asks you to choose pictures and music that are integrated into a virtual reality environment. You will be walking on a treadmill throughout each therapy session, while the therapist stands next to the treadmill and asks you questions about the pictures you chose.

The overall goal of this Phase IIa randomized controlled pilot trial is to assess the potential efficacy of two emerging treatments for post-trauma nightmares and to test the feasibility of study design and methods. Symptom change will be assessed in two treatment arms: (1) Nightmare Deconstruction and Reprocessing (NDR), an exposure-based psychotherapy; and (2) NightWare (NW), a non-exposure approach using a wristband device. The investigators will also assess the feasibility of circadian-dependent blood sampling and use of another wristband to collect physiologic data. Specific aims are: (1) Compare evidence of how well participants tolerate and comply with the two treatments and test feasibility of methods and procedures; (2) Collect additional evidence of the potential efficacy of two contrasting non-pharmacologic approaches to treating posttraumatic nightmares; (3) Explore the operational stress index (OSI) as a reliable, objective measure of sleep disturbance and nightmare events.

The goal of this clinical trial is to test the effect of omega-3 on physical performance and recovery of Soldiers.
