  2. Bottom Line • TBI is a continuum of extremely heterogeneic insults to the sub cellular and cellular structure and function of the brain; effects can be life-long • Co-morbidities (PTS, Pain, Depression) are more the rule than the exception, complicating study • Currently, physical/mental rest and education are the only validated “treatments” and there are no FDA approved therapies • Regulatory science is inadequate—a reflection of the state of the science in general. Need for validated “endpoints” for both diagnosis and treatment • Because of our limited understanding of the pathobiology, along with a paucity of biomarkers, correlating the human condition with animal models involves a degree of subjective interpretation that is scientifically tenuous and leads to an inability to even compare one model to another • The relationships between TBI, neurodegeneration and Chronic Traumatic Encephalopathy are yet to be clearly defined • Does recovered meanrecovered or does it mean compensated? • Because of the inherent complexity of the CNS, we must be prepared for instances where we must dismiss reductionism and use evidence-based “what works” (i.e. some things may simply not be knowable with current technologies) • Despite all of the above, we DO find ourselves at a “tipping point” where coordinated foundational efforts will establish the basis for future studies and real, evidence-based progress in the diagnosis and treatment of TBI

  7. DoD: Garrison vs. Deployed TBI DoD TBI Cases Worldwide 2000-2013 • 83% of all DoD TBIs from 2000-2012 occurred away from combat • Bottom Line: TBI will remain an military concern long after withdrawal from Afghanistan Number of TBI Cases Worldwide Garrison Associated Deployment Associated Source: Armed Forces Health Surveillance Center

  8. Timeline: Key TBI Policies June DoD releases 2012 MACE and Concussion Management Algorithms June Army publishes DA EXORD 242-11 mandating TBI training May Mandatory TBI screening at LRMC for all MEDEVACs April Version 3 of MACE released October ASD(HA) released a memorandum providing a standard TBI, severity of brain injury stratification, and a uniform reporting process April-July Driving and Cognitive Rehab CRs April Army and USMC revise Purple Heart criteria May USFOR-A Policy Letter #40, Afghanistan Theater Concussive Care April VA-DoD CPGs Summer MAJ Bell pilots Concussion Care Center at FOB Shank September DoDI 6490.11 published May NCAT Clinical Recommendation (CR) August MACE implemented May DoD requires mandatory cognitive baselines on SMs (NCAT/ANAM) June DTM 09-033 signed August & September Dizziness and neuroendocrine CRs

  9. TBI Theater Policy:Potentially Concussive Events Involvement in a vehicle blast event, collision, or rollover Mandatory 24-hrs downtime, medical eval, and reporting A direct blow to the head or witnessed loss of consciousness Presence within 50 meters of a blast (inside or outside) Exposure to more than one blast event (the Service member’s commander shall direct a medical evaluation)

  18. TBI Endpoints Development • A Phased approach involving key research milestones • Purpose: to identify endpoints that would be acceptable to the FDA in their regulatory review of drugs and devices that are being developed for use in the clinical setting to diagnose or treat mild TBI to moderate TBI • Two Stages: • Stage I (Years 1-2) will enable the team to lay the groundwork for the research and conduct studies required to advance the most promising endpoints • Stage II (Years 3-5) will allow the expansion of the project to proceed to larger-scale validation studies

  19. FITBIR Data Repository: Federal Interagency TBI Research A collaboration between NIH and DoD to develop a biomedical informatics system to accelerate scientific discovery and treatment in Traumatic Brain Injury Database with multiple contributors and multiple accessors 19

  20. Sec. 5. Improved Research and Development DoD, VA, HHS, and Dept of Ed in coordination with the Office of Science and Technology Policy shall establish a National Research Action Plan within 8 months of the date of this order to improve the coordination of agency research of TBI, PTSD, and other mental health conditions to reduce the number of affected men and women through better prevention, diagnosis, and treatment. National Research Action Plan shall: Establish strategies to establish surrogate and clinically actionable biomarkers for early diagnosis and treatment effectiveness Develop improved diagnostic criteria for TBI Enhance understanding of mechanisms responsible for PTSD, related injuries, and neurological disorders following TBI Foster development of new treatments for these conditions based on better understanding of underlying mechanisms Improve data sharing between agencies and academic and industry researchers to accelerate progress and reduce redundant efforts without compromising privacy Make better use of electronic health records to gain insight into the risk and mitigation of PTSD, TBI, and related injuries Include strategies to support collaborative research to address suicide prevention Presidential Executive Order 31 Aug 2012: Improving Health Care for Veterans, Service Members, and Military Families Affected by TBI

  21. National Research Action Plan • Response to President Obama’s 2012 Executive Order • Interagency Collaboration: • DoD, VA, HHS, NIDRR (Dept of Education) • Key Themes Specific to TBI Research: • Biomarkers: (Imaging, proteomic, neurophysiologic, etc.) to diagnose and monitor recovery • Diagnosis: more precise classification system, personalized/targeted diagnosis • Mechanisms: increase understanding of neuropathology • Treatment: identify and validate pharmacologic and rehabilitation treatment options

DoD Joint Program Committee Strategic Research Planning Process Requirement-based Capability Gap Prioritization Research Gaps Identification User Needs and State of Practice Analysis State of Science/Research Strategic Planning Research Prioritization Factors (Portfolio Balance, Political, Intramural Lab Capabilities, etc.) Resource Allocation (DHP, Army, SBIR) Research Prioritization Implementation Barriers Analysis (Manpower, Federal Acquisitions Regulation, Budget Related, Size of Portfolio) Program Announcements/ Requests for Proposals/Broad Agency Announcement Implementation Plan Review and Analysis (Army, Navy, Air Force, Marines, VA, ASD/HA, NIH, NIMH, Academic Subject Matter Experts) • Portfolio Analysis • Create database • Analyze Intramural and Extramural Investments • Identify Areas for Resolution • Identify Findings for Transition Transition of select Materiel Solutions to Advanced Development Dissemination of knowledge/ Clinical Practice Guidelines

  24. Summary • DoD uses a “continuum of care” model to achieve a comprehensive approach • Objective diagnostics and pharmaceutical treatment represent the largest areas of research investment • Several capabilities have been identified as showing promise for use in the clinic • Imaging, neuroplasticity, and rehabilitation represent the nearest promising research investments • Objective measures of response to treatment remain a focus for accelerating recovery • Partnerships with the VA, NIH, academia, and industry remain vital to success
