Mechanism Focus

Supports both applied (preclinical) research and clinical trials addressing

specific focus areas:

Applied research is defined as work that refines concepts and ideas into

potential solutions with a view toward evaluating technical feasibility of

diagnostic and therapeutic techniques, clinical guidance, emerging

approaches and technologies, promising new products, and/or

pharmacologic agents.

A clinical trial is defined as a prospective accrual of human subjects where an

intervention (e.g., device, drug, biologic, surgical procedure, rehabilitative

modality, behavioral intervention, or other) is tested on a human subject for a

measurable outcome with respect to exploratory information, safety,

effectiveness, and/or efficacy. This outcome represents a direct effect on the

human subject of that intervention or interaction.

Thermo-Responsive Reversibly Attachable

Patch for Temporary Intervention in Ocular Trauma

Mark Humayun, MD PhD University of Southern California

Study/Product Aim(s)

• A biocompatible, reversibly adhesive patch fabricated

from pNIPAM-on-parylene stubstrates that meets the most

significant safety and efficacy concerns for treatment of

combat-related ocular trauma.

• Device key features that would be useful in combat

scenario:

(1) Easily reversible upon cooling without damaging the

healing tissue.

(2) Ease-of-use, allowing sutureless wound closure

enabling treatment in lower tiered (2o or lower) care

centers.

Approach

Key challenges at this stage of development are: 1) sterilization effects on adhesion, 2) environmental effects (temperature during transport) on adhesion, 3) in vitro adhesion performance characterization and 4) preliminary biocompatibility. These four areas will be investigated in a stop-gate approach to assess whether this technology is viable to continue to sustained biocompatibility testing.

Goals/Milestones

CY12 Q4 Goal: – Fabrication, Quality Characterization, Exposure Test

Fabricate pNIPAM-parylene of different thicknesses (h=100nm, 400nm, 800m)

Perform baseline characterization (contact angle vs. T and FTIR)

Sterilize patches using either ETO sterilization or autoclave sterilization protocol

Extreme Thermal Exposure of Patches (120oF or -50oF for 168hrs)

Post-exposure characterization (Contact Angle vs. T and FTIR)

CY13 Goal – Performance Evaluation

Evaluate effect of sterilization and temperature protocols on adhesion

characteristics; Evaluate ease of use of patches

Initiate in vivo studies for scleral penetration closure and peritomy scarring

prevention.

CY14 Goal – Biocompatibility Assessment

Complete in vivo studies and analyze data for summary report

Accomplishments this quarter:

• 18 animals have completed the in vivo sclerotomy study using our

injector tool (left) and an interim statistical analysis of IOP results has

begun(right).

• 5 Animals have completed in vivo peritomy study and additional animals

are being scheduled for the rest of this study.

• Enucleated eyes are being prepared for histological analysis to evaluate

healing progression and tissue response to hydrogel material.

• Addresses vision gap two: Models for Visual

Dysfunction Following Blast and Concussive Trauma.

• Specific areas of the visual pathway in the eye and brain can be

interrogated by a battery of visual stimuli designed to provide a

broad inventory of system-wide functioning after traumatic brain

injury.

• By applying these tests and validating them against standard

vision testing, patients and military personnel with visual

dysfunction can then be better diagnosed and characterized to

improve outcomes of therapeutic interventions.

• Objective is to use objective reflexes of the visual system to

diagnose vision deficits and ensure effective monitoring of their

treatment, when indicated.

• Aims: 1) In normal eyes, define range of values for pupil light

reflexes, evoked potentials and eye movements to targets

changing in resolution. 2) In eyes with damage to the retina or optic

nerve, define range of values for pupil light reflexes, evoked

potentials and eye movements to targets changing in resolution.

3) In eyes with damage to primary visual cortex (V1), define range

of values for perimetric pupil light reflexes, evoked potentials and

eye movements to targets changing in resolution.

• The successful outcome of this study will allow application of

objective tests to assess patients over a wider range of impaired

consciousness and cognitive dysfunction.

Diagnosis and Treatment of Blast-Induced Hearing Loss

Problem, Hypothesis and Military Relevance

Proposed Solution Timeline and Cost

Activities FY 10 11 12

Aim 1a: Use our existing OCT device

to characterize the anatomic patterns

of damage after blast-injury in mice

Aim 1b: Develop endoscopic OCT

device for use in humans

Aim 2: Characterize the cellular,

molecular, and genetic patterns of

damage after blast-injury in mice

• Blast-induced hearing loss is common among active

military personnel.

• It produces a long-term disability that requires chronic

management through the Veterans Administration.

• Current treatments are limited to hearing aids.

• Hypothesis: Improved imaging of the ear and a detailed

understanding of the tissue, cellular, and genetic changes

that occur within the ear after blast injury will permit the

development novel and more effective treatments.

• Project: Rehabilitation; Task: Restoration and

Rehabilitation of Sensory System Traumatic Injury

• This proposal is designed to overcome current limitations

via two parallel and transformative specific aims.

• 1) To develop an endoscopic optical coherence

tomography (OCT) device to image the ear at high

resolution. This aim will result in a safe, non-invasive, and

portable device ready to be tested in humans.

• 2) To develop a mouse model of blast injury to

characterize the cellular damage and changes in gene

expression that occur after blast injury. This aim is

designed to identify molecular pathways of damage that

can be targeted by novel drugs.

• Collaborative research team: 1 clinician-scientist, 2

bioengineers, and 2 neuroscientists.

Assessing the impact of blast-related sensory impairment

on multisensory integration while maneuvering on foot

Douglas Brungart, Ph.D. The Henry M. Jackson Foundation

Study Aim(s) 1: To assess the multisensory integration ability of normal Service Members by

characterizing aurally-aided visual search (AAVS) performance as a function of visual

target acquisition time and auditory localization accuracy while SMs are physically in

stationary or moving conditions.

2: To assess the multisensory integration ability of Service Members with sensory

impairment by characterizing their aurally-aided visual search times in the stationary and

moving conditions and to compare their performance to that of unimpaired Service

Members with similar visual target acquisition times and auditory localization scores.

3. To determine the extent to which the aurally-aided visual search performance of

stationary and moving Service Members with sensory impairment can be predicted from

current clinical measures of neurological, sensory and vestibular function.

4. For those participants who proceed to the second phase of the study, to learn more

about the neurophysiological underpinnings of sensory integration disorder by comparing

results from virtual reality (Computer Assisted Rehabilitation Environment, CAREN) to an

experimental environment (Magnetoencephalography, MEG)

Approach The study will take an aurally-aided visual search paradigm that has been shown to be

effective for assessing audio-visual integration in stationary environments and port it to a moving platform that will greatly increase the sensory load and simulate dismounted combat operations.
