Not listed NOVEL AI-ENABLED WEARABLE SENSOR FOR SCRATCH MONITORING - PROJECT SUMMARY ITCH IS A DISTRESSING AND HIGHLY PREVALENT SYMPTOM ACROSS A WIDE RANGE OF DERMATOLOGICAL AND SYSTEMIC DISEASES, PROFOUNDLY IMPACTING QUALITY OF LIFE, PARTICULARLY THROUGH SLEEP DISTURBANCE AND SKIN DAMAGE. IN ATOPIC DERMATITIS (AD), ITCH IS THE HALLMARK SYMPTOM AND DRIVES BOTH DISEASE BURDEN AND THERAPEUTIC RESPONSE. HOWEVER, THE CURRENT STANDARD FOR MEASURING ITCH RELIES HEAVILY ON PATIENT-REPORTED OUTCOMES (PROS), WHICH SUFFER FROM LIMITED RELIABILITY, ESPECIALLY IN PEDIATRIC POPULATIONS AND DURING UNCONSCIOUS PERIODS SUCH AS SLEEP. SCRATCHING IS THE PRIMARY BEHAVIORAL RESPONSE TO ITCH AND OFFERS A UNIQUE, OBJECTIVE, AND QUANTIFIABLE PROXY FOR ITCH SEVERITY. OUR TEAM HAS DEVELOPED AND ITERATIVELY REFINED A NOVEL, HAND-MOUNTED WEARABLE DEVICE (ADAM) THAT USES BOTH ACOUSTIC AND MOTION SENSORS TO DETECT SCRATCHING BEHAVIOR WITH HIGH TEMPORAL RESOLUTION. IN 2021, THE FDA ACCEPTED OUR COA LETTER OF INTENT WHICH ALLOWED US TO DEVELOP, VALIDATE, AND CLINICALLY TEST THE INITIAL VERSION OF ADAM. WE DEMONSTRATED HIGH AI CLASSIFICATION ACCURACY (99%), COMPLIANCE WITH IEC 60601 SAFETY STANDARDS, AND ACHIEVED KEY MILESTONES INCLUDING BATTERY LIFE EXTENSION AND CYBERSECURITY IMPROVEMENTS. IN THIS PROPOSAL, WE AIM TO RESPOND TO RECENT FDA FEEDBACK AND FINALIZE QUALIFICATION OF THE UPDATED ADAM SENSOR TOWARDS FULL QUALIFICATION. IN AIM 1, WE WILL VALIDATE SCRATCH INTENSITY BY COMPARING AI-GENERATED OUTPUTS AGAINST FORCE PLATE MEASUREMENTS UNDER CONTROLLED CONDITIONS. IN AIM 2, WE WILL DEVELOP AND VALIDATE NEW ALGORITHMS FOR ESTIMATING BODY SURFACE AREA (BSA) SCRATCHED AND BODY LOCATION OF SCRATCHING USING SUPERVISED VIDEOGRAPHY. IN AIM 3, WE WILL CONDUCT A 1-WEEK CLINICAL VALIDATION IN 30 PEDIATRIC AND ADULT AD PATIENTS USING INFRARED NIGHTTIME VIDEOGRAPHY AND DAILY DIARIES AS GOLD STANDARDS. THIS WORK WILL CLOSE THE GAP BETWEEN SUBJECTIVE PROS AND OBJECTIVE BEHAVIORAL BIOMARKERS OF ITCH, FULFILLING A CRITICAL NEED IN DERMATOLOGY AND DRUG DEVELOPMENT. OUR VALIDATED DIGITAL ENDPOINT WILL DIRECTLY SUPPORT REGULATORY-GRADE APPLICATIONS IN AD AND FORM THE FOUNDATION FOR BROADER DEPLOYMENT IN OTHER PRURITIC DISORDERS. THE PROPOSED RESEARCH ALIGNS WITH THE FDA'S CLINICAL OUTCOME ASSESSMENT QUALIFICATION PROGRAM AND THE NIH'S INTEREST IN ADVANCING DIGITAL HEALTH TECHNOLOGIES FOR REAL-WORLD PATIENT MONITORING. $0 1/15/26 Not listed NOVEL AI-ENABLED WEARABLE SENSOR FOR SCRATCH MONITORING - PROJECT SUMMARY ITCH IS A DISTRESSING AND HIGHLY PREVALENT SYMPTOM ACROSS A WIDE RANGE OF DERMATOLOGICAL AND SYSTEMIC DISEASES, PROFOUNDLY IMPACTING QUALITY OF LIFE, PARTICULARLY THROUGH SLEEP DISTURBANCE AND SKIN DAMAGE.
