Traumatic Brain Injury Clinical Trials

Traumatic brain injury (TBI) accounts for approximately 2.5 million visits to emergency departments in the United States each year. After decades of research, management strategies for severe TBI (sTBI) patients are still evolving. Optimizing intracranial pressure (ICP) and cerebral perfusion pressure (CPP) are paramount in the management of these patients and placement of these monitors is the current standard-of-care. However, monitoring brain oxygenation (PbtO2) with invasive intraparenchymal monitors is currently under investigation in the management of severe TBI and placement of these monitors is gaining widespread use. This has opened the door for the use of tiered therapy to optimize ICP and PbtO2 simultaneously. Current evidence indicates that correction of ICP, CPP and PbtO2 in sTBI requires optimized analgesia and sedation. Ketamine is one of the few drugs available that has both sedative and analgesic properties and does not commonly compromise respiratory drive like opioids and sedative-hypnotics. However, traditionally, ketamine has been viewed as contraindicated in the setting of TBI due to concerns for elevation in ICP. Yet, new data has cast this long-held assumption into significant doubt. Hence the present pilot study will characterize the neurophysiological response to a single dose of ketamine in critically-ill TBI patient with ICP and PbtO2 monitoring. Read Less

A moderate traumatic brain injury (TBI) occurring in early or middle adulthood might have long-lasting effects on the brain that can accelerate the decline of physical and cognitive function in older age. The proposed study seeks to better understand the implications of aging with a TBI, in order to help Veterans maintain their health and independence. The overarching hypothesis of this new line of research is that participants who experienced a moderate TBI in early or middle adulthood (at least 15 years prior to study enrollment) will have poorer performance on balance and cognitive tests, despite self-reporting no persistent motor or cognitive impairment from the TBI. The investigators also seek to evaluate the potential for practice-based learning and improvement of complex balance tasks in this population, to gain experience for conducting future rehabilitation studies. The long term goal of this line of research is to design rehabilitative and lifestyle interventions to preserve brain health and function in Veterans who have previously experienced a TBI. Read Less

The purpose of this research study is to test whether a portable goggle system (I-PAS) is good at diagnosing mild traumatic brain injury (mTBI) in a community setting. The goal is to determine whether the IPAS goggle system can be used reliably in an urgent care or emergency department setting. Read Less

Traumatic brain injury (TBI) is a major public health concern, particularly among older adults (OAs) ≥ 65 years of age. Each year in the United States, TBI results in over 600,000 emergency department visits and hospitalizations among OAs. Mild TBI (mTBI) accounts for 80% of all TBI in OAs and is quite understudied in this rapidly growing population. mTBI, is mild in name only, as it can result in dysfunction in multiple cognitive domains, including attention, processing speed, executive functioning and memory and has been shown to be associated with progressive brain atrophy and increased susceptibility to neurodegenerative disorders. Cognitive rehabilitation therapy is an evidence-based approach that can successfully improve cognitive impairment following TBI. Virtual reality (VR) is emerging as a technology that can assess cognitive impairment and provide a neurorehabilitation modality (NRM) to improve cognitive decline post TBI. Not only can VR provide a variety of environments like those encountered in real life and be adapted to varying levels and types of cognitive disability, but it can also be used safely in a patient's home with minimal equipment. Yet, despite the promise of cognitive rehabilitation using VR among OAs, very few studies to date have assessed the efficacy of VR cognitive rehabilitation in TBI. The aim of this study is to assess the effect and collect data on the efficacy and feasibility of a virtual reality application as a neurorehabilitation modality on executive functioning (attention, immediate memory, and visual-spatial skills) in OAs with mTBI. The hypothesis is that The use of VR mediated cognitive exercises post mTBI will be associated with improved executive function at 6-weeks post-randomization compared to the control group. Read Less

This randomized waitlist control trial will evaluate the effects of a psychoeducational intervention called Resources for Enhancing All Caregivers' Health - Traumatic Brain Injury (REACH TBI) to decrease caregiver strain (primary outcome) and improve caregiver self-efficacy, anxiety, depression, and health care frustrations (secondary outcomes). This study will modify and adapt an award-winning caregiver intervention, Resources for Enhancing All Caregivers Health in the Department of Veterans Affairs (REACH VA), to support the needs of Caregivers of Veterans and Service Members with TBI.

The CONNECT-TBI Trial aims to develop safe, effective treatments for complex mTBI that improve cognitive functioning. Based on the compelling preliminary data generated by our study team, the objective of this study is to conduct a randomized, double-blinded, sham-controlled Phase II clinical trial of APT-3 combined with rTMS, HD-tDCS, or sham to treat cognitive control deficits in Veterans with complex mTBI and PPCS. At the Baseline Visit, participants will undergo demographic, neuropsychological, behavioral, and quality of life testing. They will also undergo structural MRI to permit modeling of their brain, resting/task-related fMRI to identify the CCN, and pseudocontinuous arterial spin labeling (pCASL) and diffusion tensor imaging (DTI) to assess for other pathologies. They will then be randomized to 16 sessions of APT-3 with concurrent rTMS, HD-tDCS, or sham stimulation delivered to the unique functional left dorsolateral prefrontal cortex (DLPFC), a primary node of the CCN. Lastly, they will repeat all baseline tests, and report on 3- and 6-month recovery levels to establish longevity and stability of subjective benefit. Given that this individualization protocol has never been attempted for cognitive rehabilitation in military mTBI, we expect this trial will generate useful effect sizes for HD-tDCS and rTMS to be used for powering the next step, a Phase III multi-center trial.

The purpose of this study is to demonstrate the feasibility and utility of SIT delivered asynchronously (self-paced) via fully virtual platform with and without the aid of a mobile health application and to determine initial change over baseline in terms of reduction in PTSD symptoms and improvement in resiliency in participants receiving the virtual SIT prototype, using Linear Mixed Models (LMMs), Read Less

The goal of this clinical trial is to test the safety of the drug Angiotensin (1-7) and learn whether it works well as a treatment in people who have suffered a moderate to severe traumatic brain injury (TBI). The main questions this trial aims to answer are: * Is Angiotensin (1-7) safe? * Does Angiotensin (1-7) improve mental functioning and reduce physical signs of brain damage in people who have suffered a moderate to severe TBI? Participants will: * Complete 21 days of study treatment consisting of a once-daily injection. * Provide blood samples. * Undergo two magnetic resonance imaging (MRI) scans of the brain. * Complete specific tasks and questionnaires that allow researchers to evaluate the participant's brain and psychological functioning. Researchers will compare three groups: two groups that receive different doses of Angiotensin (1-7) and one group that receives a look-alike treatment with no active drug. This will allow researchers to see if the drug has any negative effects and whether it improves mental functioning and physical signs of brain damage after a TBI. Read Less
