7:55 am Chairperson’s Opening Remarks
Andreas Jeromin, Ph.D., Chief Scientific Officer, Cohen Veterans Bioscience
8:00 am Center-TBI; Early Results of a Comparative Effectiveness Research Study
In this presentation, Dr. Peul will describe the practice variation in TBI care in Europe. Do differences in surgical & critical care influence outcome? The drawback of observational studies compared to RCT’s can be overthrown by modern mathematical methods. As the observed practice variation in Center-TBI is quite enormous between countries and even within countries there is a great need for evidence-based guidelines. Within this lecture Dr. Peul will present the differences in healthcare infrastructure, timing of surgery and critical care within the Center-TBI cohort of 5400 patients.
Wilco Peul, MD, Ph.D., Professor & Chair, University Neurological Center Holland, UNCH Leiden & The Hague

8:50 am Toward Improved Analytical and Clinical Validation of Neurotrauma Blood Biomarkers
Cheryl Wellington, Ph.D., Professor, Department of Pathology and Laboratory Medicine, Faculty of Medicine, University of British Columbia
9:15 am Traumatic Brain Injury Testing in the ER
We have lots of questions, but what are the answers?
~5 million annual ER visits, <5% with positive testing? Is this as good as it gets? Questions we should be asking include:
♦ Are you really safe after a negative CT scan of the head?
♦ Can you go home?
♦ Can you go back to work?
♦ What if you get hit again, are you going to be fine?
♦ Are there any other tests that you should be getting?
♦ Do you have acute traumatic encephalopathy?
Objective measures are coming and will change the standard of care for how we currently manage traumatic brain injury. This talk will cover these existing and future directions for acute testing in patients with suspected TBI.

9:40 am Refreshment Break/Poster Viewing/Exhibit Viewing
10:10 am Saliva Biomarkers for Adolescent Concussion
Neuronal exosomes within saliva contain brain-related microRNA that can provide a window into the injured brain. Previously, Dr. Hicks and his team have shown that saliva microRNA profiles reflect cerebrospinal fluid microRNA profiles after traumatic brain injury, and that saliva microRNA can be used to predict the severity and duration of concussion symptoms. Here, he will present results from their follow up study, involving over 650 saliva samples from over 300 participants, which continue to demonstrate the promise of this novel, non-invasive class of biomarkers for assessing and managing adolescent concussion.
Steven Hicks, MD, Ph.D., Assistant Professor of Pediatrics, Penn State College of Medicine
10:35 am Presentation to be Announced
Geoffrey T. Manley, MD, Ph.D., Margaret Liu Endowed Prof. in Traumatic Brain Injury, Weill Institute for Neurosciences, Prof. & Vice Chairman of Neurological Surgery, Co-Director, Brain & Spinal Injury Center, UCSF, Chief of Neurosurgery, Zuckerberg San Francisco General Hospital & Trauma Center
11:00 am Precision Imaging of Neuroinflammation After Traumatic Brain Injury
Dr. Coughlin will present emerging molecular imaging data that may shape the application of precision medicine in TBI. The presentation will review key concepts in imaging inflammation in the living brain, and will highlight recent data from imaging the neuroinflammatory response after repeated TBI in collision sports. Recent findings will be discussed in the context of informing new therapeutic strategies relevant to treating many types of TBI.
Jennifer M. Coughlin, MD, Assistant Professor, Department of Psychiatry and Behavioral Sciences, Johns Hopkins University School of Medicine
11:25 am Regulatory Guidance for Developers of New Devices for TBI Diagnosis: Blood-based Biomarkers, Imaging and Other Point-of-Care Devices
In this session, Mr. Hoffmann will discuss important considerations that developers of new devices for TBI must take into account during the regulatory process. Topics to be covered include, qualification vs approval and clearance, clinical validation, FDA review timelines, industry/FDA communication and pre-submissions.
Michael Hoffmann, Associate Director, Office of Neurological and Physical Medicine Devices, Office of Product Evaluation and Quality, Center for Devices & Radiological Health, US Food & Drug Administration

1:05 pm Longitudinal Evolution of Brain Injury Biomarkers: Implications for the Next Generation of Clinical Trials
Ramon Diaz-Arrastia, MD, Ph.D., Associate Director for Clinical Research, Center for Neurodegeneration and Repair, Director of TBI Clinical Research Center, Presidential Professor of Neurology, Penn Medicine
1:30 pm Use of a Gyrencephalic Animal Model to Study the Effects of Blast Injury and Related Tau Protein Changes
Dr. Juliano will discuss the effect of blast and other injuries on the cerebral cortex of a gyrencephalic animal (the ferret). Using an animal with brain morphology to similar to that of the human is essential to further assess the impact of injury, as these animals possess sulci and gyri, an increased amount of white matter, and the position of the hippocampus in location similar to that of the human. The ferret shows a neuropathologic profile with interesting features that include increased levels of phosphorylated tau and changes in the ratio of the tau isoforms 3R and 4R.
Sharon Juliano, Ph.D., Professor of Anatomy, Physiology and Genetics, Uniformed Services University of the Health Sciences
1:55 pm Neurotrauma Priorities to Address Capability Gaps for Acute Management of TBI in Future Combat Operations
Future Multi-Domain Operations will result in significantly delayed casualty evacuation from combat. Dr. J.B. Phillips, Manager of the Neurotrauma Portfolio at Combat Casualty Care Research Program (CCCRP) will discuss the need for closing military-relevant gaps across a broad range of research areas to improve the diagnosis, management and treatment of TBI. Research focused on enhancing capabilities at the point of greatest need, including life-saving interventions to be rendered immediately post-injury, during periods of prolonged care in theater, and during transport/en route care within and from theater. Dr. Phillips will also discuss how CCCRP fits into the US Army Medical Research and Development Command (MRDC) and current/future funding opportunities.
James B. Phillips, MBA, Ph.D., PMP, Combat Casualty Care Research Program, US Army Medical Research and Development Command
2:20 pm Lessons from the MODEL-AD and TREAT-AD Consortia for Pre-Clinical TBI Research
Over the last several years, the National Institutes on Aging has invested substantial resources to enhance and speed translational research towards developing effective therapeutics for Alzheimer’s disease and related dementias. This includes the Model Organism Development and Evaluation for Late-Onset Alzheimer’s Disease (MODEL-AD) and Target Enablement to Accelerate Therapy Development for Alzheimer’s disease (TREAT-AD) consortia. These consortia seek to develop and characterize more predictive animal models of late-onset AD (MODEL-AD) and identify and characterize novel therapeutic targets for Alzheimer’s disease (TREAT-AD). Given accumulating genetic, epidemiology and systems biology evidence suggesting potential links between traumatic brain injury and Alzheimer’s disease and related dementias, this presentation will provide an overview of the MODEL-AD and TREAT-AD consortia and the potential to leverage this work to enhance and speed translational research towards developing effective therapeutics for traumatic brain injury.
Bruce Lamb, Ph.D., Roberts Family Chair in Alzheimer's Disease Research, Executive Director, Stark Neurosciences Research Institute, Indiana University School of Medicine
2:45 pm One Bite at a Time: Clinical Trials for Specific Symptoms and Deficits of TBI
Despite substantial investment of time and resources, over 30 late-phase clinical trials in traumatic brain injury (TBI) have failed to translate a therapeutic. There are very few solutions based on solid scientific evidence for treating patients with TBI. In recent years, there have been several examples of successful clinical trials focused on one symptom or subdomain at a time, in the specific sub-populations of patients most likely to benefit. Dr. Brody will present an overall framework for future clinical trials and discuss advantages of the “one bite at a time” approach to treating TBI. Exemplar trials will be presented to highlight the importance of trial design, domain-specific outcomes, and patient selection.
David Brody, MD, Ph.D., Director, Center for Neuroscience and Regenerative Medicine, Uniformed Services University of the Health Sciences
3:10 pm Refreshment Break/Poster Viewing/Exhibit Viewing
3:40 pm Novel Therapeutic Routes Undergoing Pre-Clinical Research for Traumatic Brain Injury
Upwards of 5 million people in the U.S. alone are currently living with TBI-related disability, which is characterized by both acute and chronic phases. This presentation will discuss novel therapeutic approaches to both, with the goal of mitigating neuronal damage and neuropsychiatric impairment.
Andrew Peiper, MD, Ph.D., Harrington Investigator, Director of Neurotherapeutic Discovery, Harrington Discovery Institute, University Hospitals
4:05 pm New Pharmacological Interventions to Reverse Sex-dependent Behavioral and Cell-specific Deficits After Mild Repetitive Head Trauma
Repetitive mild head trauma can recapitulate higher cognitive deficits observed also in humans such as increased risk-taking behavior. We demonstrated that we can fully and permanently reverses sex-dependent behavioral and cellular deficits after mild, repetitive head trauma. We have behavioral data as well electrophysiology and structural and immunohistochemistry data along with the pharmacological intervention.
Susanna Rosi, Ph.D., Professor & Director of Neurocognitive Research, Brain and Spinal Injury Center, Weill Institute for Neuroscience, University of California San Francisco

8:00 am Pharmacological Augmentation of KCNQ (“M-type,” Kv7) K+ channels as a Novel Approach to Prevent Brain Damage and Dysfunction After Multiple Types of Traumatic Brain Injury
Dr. Shapiro will present his recent findings from his multi-lab project using mouse models that seeks to use pharmacological enhancement of M-type K+ currents in neurons to prevent the deleterious cascade of events that often lead to brain damage and dysfunction. These include the development of acute seizures and long-term epilepsy, a mal-adaptive inflammatory response characterized by microgliosis, astrogliosis and other inflammatory mediators, the breakdown of the normal blood-brain barrier, the wide-spread death of neurons, and cognitive and motor dysfunction. His team's results suggest that this approach has the potential to become a powerful and widespread therapeutic intervention in the clinic, the emergency room and on the battlefield.
Mark Shapiro, Ph.D., Professor, Department of Cellular and Integrative Physiology, Neuroscience Program, University of Texas Health Science Center
8:25 am Can Brain Biomarkers Identify a Subset of Moderate to Severe TBI Patients with Improved Outcome After Progesterone Treatment? A Secondary Analysis of the ProTECT III Trial
In this presentation, Dr. Bazarian will:
♦ Review the main findings of the Protect III trial, which were negative
♦ Review the biomarker project embedded within this trial (BioProTECT)
♦ Review methods used to re-analyze the Protect data using biomarker values, and the results
♦ Review implications and limitations of results
Jeff Bazarian, MD, MPH, Professor of Emergency Medicine, Neurology, Neurosurgery, and PHS, University of Rochester
(NON CME) 8:50 am Neuroprotection by Intranasal ST266, a Novel Amnion Cell-derived Secretome
ST266 is a novel, cGMP-produced secretome secreted by Amnion-derived Multipotent Progenitor (AMP) cells. AMP cells are produced by culturing a select population of amnion-derived epithelial cells under proprietary conditions. This cell secretome is anti-inflammatory, anti-apoptotic and neuroprotective. We have successfully demonstrated intranasal delivery of this protein mixture to the brain via the olfactory nerves. Neuroprotection in animal models has now propelled this research to human clinic studies.

1:15 pm Neural Gain Modulation in Mild TBI: A Proposed New Direction for Research and Clinical Practice
A holistic understanding of the neurological, cognitive, physical, and psychological sequelae of mild traumatic brain injury (TBI) remains elusive despite substantial research efforts. Dr. Hershaw will describe how effects of TBI on neural gain modulation may underlie the variable constellation of non-specific symptoms observed in acute, sub-acute, and chronic stages post-injury. The goal of this presentation is to introduce a novel theoretical framework that may unify an otherwise fractured understanding of mild TBI and, thus, generate worthwhile and fruitful lines of basic, translational, and clinical research.
Jamie Hershaw, Ph.D., Research Scientist, Defense and Veterans Brain Injury Center
1:40 pm Clinical Signatures and Neuropathological Correlates of Post Traumatic Neurodegeneration
This talk will provide an updated overview of current knowledge regarding clinical phenotypes of post-TBI functional and neurocognitive decline, neuropathological processes that may (or may not) represent mechanistic contributors to clinical decline, and clinical-pathological associations. Dr. Dams-O'Connor will also share recent findings from the Late Effects of TBI (LETBI) study.
Kristen Dams-O'Connor, Ph.D., Associate Professor, Director, Brain Injury Research Center, Icahn School of Medicine at Mount Sinai
2:05 pm Machine Learning Prediction of Chronic AD-like Alterations in Default Mode Networks Based on the Acute Cognitive Impairment Profiles of Geriatric TBI Patients
By leveraging functional MRI findings and machine learning techniques, Dr. Irimia and his team have uncovered evidence that geriatric mild TBI (mTBI) is associated with fronto-temporo-limbic alterations in the brain's default mode network (DMN), and that these alterations are statistically indistinguishable from similar deviations from normality observed in AD. Such degradation of functional circuits is significantly correlated with acute post-traumatic deficits of working memory, attention and processing speed. These findings establish a statistical association between geriatric mTBI, post-traumatic cognition and AD-like DMN degradation, and advance the important goal of acutely forecasting mTBI patients’ chronic alterations of brain connectivity along AD-like functional trajectories.
Andrei Irimia, Ph.D., Assistant Professor of Gerontology, Biomedical Engineering and Neuroscience, Leonard Davis School of Gerontology, University of Southern California
2:30 pm Lessons Learned from a Pediatric Concussion Specialty Clinic
In this presentation, Dr. Slomine will discuss an interdisciplinary specialty clinic model of care for children with mild traumatic brain injury. Recent findings generated from clinic data including course and predictors of time to recovery in school-aged children and unique symptoms in preschool-aged children will be described. Additionally, the new data about the relationship among physical and cognitive activity and symptom resolution will be discussed.
Beth S. Slomine, Ph.D., ABPP, Co-Director, Center for Brain Injury Recovery, Kennedy Krieger Institute, Associate Professor of Psychiatry and Behavioral Sciences, Johns Hopkins University School of Medicine
2:55 pm Long-Term Outcomes Following Pediatric TBI Pre-clinical Studies
While mortality of pediatric TBI has improved, survivors often deal with long-term cognitive and psychosocial deficits in adolescence and adulthood. Unfortunately, there are no pathology-based therapies to limit these deficits in survivors of childhood TBI. One of Dr. Huh's goals is to develop clinically-relevant pre-clinical models of pediatric TBI that demonstrate long-term cognitive and psychosocial deficits and test mechanistic-based therapies with the ultimate goal of translating this to the human population. In this presentation, He will describe recent findings that he and his team have observed in the lab.
