Traumatic Brain Injury Clinical Trials

There are no therapeutic agents that have been shown to improve outcomes from severe traumatic brain injury (TBI). Critical barriers to progress in developing treatments for severe TBI are the lack of: 1) monitoring biomarkers for assessing individual patient response to treatment; 2) predictive biomarkers for identifying patients likely to benefit from a promising intervention. Currently, clinical examination remains the fundamental tool for monitoring severe TBI patients and for subject selection in clinical trials. However, these patients are typically intubated and sedated, limiting the utility of clinical examinations. Validated monitoring and predictive biomarkers will allow titration of the dose of promising therapeutics to individual subject response, as well as make clinical trials more efficient by enabling the enrollment of subjects likely to benefit. Glial fibrillary acidic protein (GFAP), neurofilament light chain (NfL) and high sensitivity c-reactive protein (hsCRP) are promising biomarkers that may be useful as 1) monitoring biomarkers; 2) predictive biomarkers in severe TBI trials. Although the biological rationale supporting their use is strong, significant knowledge gaps remain. To address these gaps in knowledge, we propose an ancillary observational study leveraging an ongoing severe TBI clinical trial that is not funded to collect biospecimen. The Hyperbaric Oxygen in Brain Injury Treatment (HOBIT) trial, a phase II randomized control clinical trial that seeks to determine the dose of hyperbaric oxygen therapy (HBOT) that that has the highest likelihood of demonstrating efficacy in a phase III trial. The proposed study will: 1) validate the accuracy of candidate monitoring biomarkers for predicting clinical outcome; 2) determine the treatment effect of different doses of HBOT on candidate monitoring biomarkers; and 3) determine whether there is a biomarker defined subset of severe TBI that responds favorably to HBOT. This proposal will: 1) inform a go/no-go decision for a phase III trial of HBOT by providing adjunctive evidence of the effect of HBOT on key biological pathways through which HBOT is hypothesized to affect outcome; 2) provide evidence to support further study of the first monitoring biomarkers of severe TBI; 3) increase the likelihood of success of a phase III trial by identifying the sub-population of severe TBI likely to benefit from HBOT; 4) create a repository of TBI biospecimen which may be accessed by other investigators.

Injuries affecting the central nervous system may disrupt the cortical pathways to muscles causing loss of motor control. Nevertheless, the brain still exhibits sensorimotor rhythms (SMRs) during movement intents or motor imagery (MI), which is the mental rehearsal of the kinesthetics of a movement without actually performing it. Brain-computer interfaces (BCIs) can decode SMRs to control assistive devices and promote functional recovery. Despite rapid advancements in non-invasive BCI systems based on EEG, two persistent challenges remain: First, the instability of SMR patterns due to the non-stationarity of neural signals, which may significantly degrade BCI performance over days and hamper the effectiveness of BCI-based rehabilitation. Second, differentiating MI patterns corresponding to fine hand movements of the same limb is still difficult due to the low spatial resolution of EEG. To address the first challenge, subjects usually learn to elicit reliable SMR and improve BCI control through longitudinal training, so a fundamental question is how to accelerate subject training building upon the SMR neurophysiology. In this study, the investigators hypothesize that conditioning the brain with transcutaneous electrical spinal stimulation, which reportedly induces cortical inhibition, would constrain the neural dynamics and promote focal and strong SMR modulations in subsequent MI-based BCI training sessions - leading to accelerated BCI training. To address the second challenge, the investigators hypothesize that neuromuscular electrical stimulation (NMES) applied contingent to the voluntary activation of the primary motor cortex through MI can help differentiate patterns of activity associated with different hand movements of the same limb by consistently recruiting the separate neural pathways associated with each of the movements within a closed-loop BCI setup. The investigators study the neuroplastic changes associated with training with the two stimulation modalities. Read Less

This project will adapt a currently deployed Clinical Decision Support (CDS) system to deliver a VTE prevention guideline for adult patients with traumatic brain injury (TBI). We believe this is an ideal PCOR use case given PCORI's continued effort to combat VTE in trauma and our experience previously implementing this guideline. The Our overall goal is to successfully scale, evaluate, and maintain an interoperable TBI CDS across 7 total institutions. Read Less

The purpose of this study is to examine the feasibility and preliminary efficacy of using transcutaneous auricular vagus nerve stimulation (tVNS) to enhance cognitive recovery in patients with mild-moderate traumatic brain injury (TBI). Read Less

The goal of this clinical trial is to evaluate GetUp\&Go, a program for promoting increased physical activity in individuals at least 6 months post moderate-to-severe traumatic brain injury. GetUp\&Go is a remotely delivered 10-week program that includes one-on-one sessions with a therapist and a mobile health application (RehaBot). The main question is whether participants in the 10-week GetUp\&Go program increase their physical activity, and exhibit associated benefits in mental and physical health, relative to those who are put on a waitlist. * Question 1: Do participants who receive immediate treatment with GetUp\&Go show more increased physical activity, measured by accelerometer activity counts per day, and improve more on secondary outcomes, such as self-reported physical activity, emotional function, fatigue, sleep, pain, and health-related quality of life, compared to their baseline, relative to those who are put on a waitlist? * Question 2: Do participants who have continued access to the mobile health component of the intervention, RehaBot, show better maintenance of physical activity gains compared to those who no longer have access to RehaBot? * Question 3: Are individual participant characteristics associated with participants' response to the treatment program?

The purpose of this research is to learn if different behavioral interventions can change walking behaviors over 12-weeks, in older adults who have previously suffered a non-penetrating mild or moderate TBI. Participants will provide information and be screened for eligibility via phone screening call (verification of age, confirmation that the participant is not currently on any medication that affects the central nervous system, and verification that the subject can participate in exercise, brief TBI history). Baseline testing will take place at the Center for Cognitive and Brain Health and Northeastern University Biomedical Imaging Center, for the baseline magnetic resonance imaging, in the interdisciplinary science and engineering complex on Northeastern University's campus. In person testing will take place over one session. The study period lasts 12 weeks, during which all participants will 1. Receive a weekly phone call with study staff and 2. Wear a wrist-worn Fit Bit tracker. A remote participation option is available for those who cannot travel to Northeastern University. Read Less

The intent of this study is to establish technical feasibility in a clinical population (PTSD, with or without mild TBI) of personalized TMS-fNIRS technology.
