1 Anthony E. Pusateri, PhD FOUO 4/30/2015 3:17 AM Slide 1 Joint Hemostatics In-Progress Review: Introduction 25 April 2012

2 Anthony E. Pusateri, PhD FOUO 4/30/2015 3:17 AM Slide 2 Top cause of preventable DOW*: Hemorrhage76% Burn13% TBI 6% MOF 3% Airway 1% *DOW: Died of Wounds at Role 3+ Background: Causes of Death on the Battlefield Non-survivable: 81% Potentially survivable: 19% 33% Tourniquetable 67% Non-compressible/ non-tourniquetable (internal injuries) Central Nervous System Hemorrhage: 84% Other Airway Compromise Non-survivable injuries: Catastrophic TBI Cardiac laceration / puncture Thoracic great vessel injury Intra thoracic tracheal injury Open pelvis All Deaths Kelly et al., 2008 Potentially Survivable Deaths: 75% KIA and 25% DOW

3 Anthony E. Pusateri, PhD FOUO 4/30/2015 3:17 AM Slide 3 DoD Joint Program Committee for Combat Casualty Care 1.Improved ability to diagnose, resuscitate, and stabilize casualties with survivable wounds 2.Improved ability to stop internal bleeding and external bleeding 3.Improved therapy for hemorrhagic shock and head injury Top Three Needs

4 Anthony E. Pusateri, PhD FOUO 4/30/2015 3:17 AM Slide 4 DoD Hemorrhage and Resuscitation Program/Portfolio Scope and Purpose Scope: The Hemorrhage and Resuscitation R&D program includes DoD efforts in the general areas of hemorrhage control, fluid resuscitation, blood products, transfusion, and pathophysiologic responses to traumatic hemorrhage, with a view ranging from basic and discovery research through clinical develoment Purpose: Conduct research and development to provide improved methods, drugs, and devices to stop bleeding, restore lost blood volume, and mitigate the consequences of hemorrhage. Reduce mortality by up 16% overall.

5 Anthony E. Pusateri, PhD FOUO 4/30/2015 3:17 AM Slide 5 Steering Committee Role The present combination of Service programs, major Defense Health Program initiatives, significant CSI efforts, and numerous smaller initiatives make coordination extremely important Joint/Interagency Steering Committee Role: –Advise the JPC-6 and Service R&D programs –Review overall program and provide recommendations –Develop (and update) a DoD-level strategic plan –Produce recommendations and position papers regarding significant strategic level issues relevant to the program –Facilitate harmonization of research requirements, objectives, and programs; ensure that Service-unique requirements are also met –Promote communication and cooperation among programs

6 Anthony E. Pusateri, PhD FOUO 4/30/2015 3:17 AM Slide 6 Strategic Approach: Major Efforts Major EffortGoal Improved Blood ProductsDevelop safer and more logistically supportable blood products for transfusion Damage Control ResuscitationIdentify the best ways to use existing and newly developed blood products, drugs, and fluids (Including Transfusion Practice using existing products-CPGs) Coagulopathy of TraumaElucidate mechanisms to identify diagnostic and therapeutic targets for the development of rapid diagnostics and drugs to prevent or treat coagulopathy of trauma Immune/Inflammatory ModulationEvaluate promising approaches and identify key mechanisms leading to the long-term ability to modulate inflammatory responses of the patient Metabolic and Tissue Stabilization Evaluate promising approaches and identify key mechanisms leading to long-term ability to modulate/stabilize metabolic responses (Including oxygen delivery) HemostaticsEvaluate/identify existing products and develop new products or procedures to control bleeding

7 Anthony E. Pusateri, PhD FOUO 4/30/2015 3:17 AM Slide 7 DoD Activities in Hemostatics The major gaps in hemostatics: –Non-compressible and Junctional bleeding Areas of research and testing in hemostatics –DARPA Wound Stasis Program to develop a field treatment for intracavitary bleeding –Hemostatic drugs –Devices for junctional bleeding (CROC; hemostatic pellets) –Other approaches to noncompressible hemorrhage (e.g. abdominal tourniquet) –Endovascular hemostasis –Improved topical hemostatics (Internal Use) –Improved topical hemostatics (External Use) –Improved limb tourniquets Primarily R&D Primarily Testing

8 Anthony E. Pusateri, PhD FOUO 4/30/2015 3:17 AM Slide 8 DoD Hemorrhage R&D Investment By Major Effort ($M) Major EffortFY10FY11FY12FY13 Improved Blood Products Damage Control Resuscitation Coagulopathy of Trauma Inflammatory Modulation Metabolic and Tissue Stabilization Hemostatics Total DoD Spending on hemostatics has been ~$15-20M/year and declining

9 Anthony E. Pusateri, PhD FOUO 4/30/2015 3:17 AM Slide 9 Status We currently effective hemostatic dressings and limb tourniquets that are largely effective The major technology gaps in hemostatics are Non- compressible and Junctional bleeding We continue to test new dressings and tourniquets (for “tourniquetable” and compressible hemorrhage)

10 Anthony E. Pusateri, PhD FOUO 4/30/2015 3:17 AM Slide 10 Issues Lack of agreement on why (what gap are we trying to fill?) Disagreements on what dressings and tourniquets to test and how to test them Need improved coordination and communication to enhance efficiency Funding is declining – need to ensure we are focusing (limited) resources on the right priorities “Testing” takes away resources from research and development efforts – need alternative funding and need focus Frustration - user community that we are not testing dressings of interest Frustration - research community – why use S&T funds?

11 Anthony E. Pusateri, PhD FOUO 4/30/2015 3:17 AM Slide 11 Some Recent Progress Recent efforts to establish consensus testing approaches (with Inter-Service Agreement) DHP funding for FY12 – Dressings and Tourniquets Possible DHP 6.7 funds Improved coordination still needed

12 Anthony E. Pusateri, PhD FOUO 4/30/2015 3:17 AM Slide 12 Approach Joint In-progress Review on Hemostatics –This will be the first of a series of recurring meetings (probably 1x/yr in person and 1x/yr conference call) Recommended by the Joint Program Committee for Trauma (JPC-6) Endorsed by: –Principal Assistant for Acquisition, USAMRMC (Dr. Bertram, SES) –Army Combat Casualty Care Research Program (RAD2; COL Hack) –Defense Medical Materiel Program Office –DoD Hemorrhage and Resuscitation Research and Development Steering Committee –Others

13 Anthony E. Pusateri, PhD FOUO 4/30/2015 3:17 AM Slide 13 Goals of the Conference Agree on a framework for linking needs, testing, and acquisition processes for hemostatic dressings and limb tourniquets Establish an agreed list of hemostatic dressings and limb tourniquets (and related topical hemostatics) that require testing in FY13 Share latest testing data for hemostatic dressings and tourniquets Define/confirm standardized models for testing Identify organization(s) that will/propose to perform testing for FY13 (Not-directive – requires chain of command approval, etc.) Identify funding source for testing Define/revise desirable characteristics for new topical hemostatics and limb tourniquets Improve integration with acquisition processes Provide a predictable forum for dissemination of information and planning
