FORM 990, PAGE 2, PART III, LINE 4A	AWARENESS: THE RP FOUNDATION PARTNERED WITH MCLAREN TROPHY AMERICA DURING THE 2025- 2026 RACING SEASON TO SIGNIFICANTLY EXPAND AWARENESS AND SUPPORT FOR RP RESEARCH. RACE FOR RP BRANDING APPEARED ON EVERY MCLAREN TROPHY AMERICA RACE CAR THROUGHOUT THE SEASON, WHILE ON-SITE ACTIVATIONS AND PADDOCK ENGAGEMENT OPPORTUNITIES CONNECTED THOUSANDS OF FANS WITH THE FOUNDATION'S MISSION. THE PARTNERSHIP ALSO INTRODUCED THE "WIN A HOT LAP" FUNDRAISING CAMPAIGN, WHICH ENCOURAGED FAN PARTICIPATION THROUGH DONATIONS AND HELPED ATTRACT NEW SUPPORTERS. THE COLLABORATION GENERATED BOTH FUNDRAISING SUCCESS AND INCREASED VISIBILITY THROUGH CHARITY AUCTIONS HELD AT THE INDIANAPOLIS MOTOR SPEEDWAY AND THE MCLAREN TECHNOLOGY CENTRE IN WOKING, UNITED KINGDOM. TOGETHER, THESE EFFORTS BROADENED AWARENESS OF RP AND AUTOIMMUNE DISEASE RESEARCH, ENGAGED NEW AUDIENCES WITHIN THE MOTORSPORTS COMMUNITY, AND CONTRIBUTED TO ONE OF THE MOST IMPACTFUL YEARS IN RACE FOR RP'S HISTORY. THE PARTNERSHIP HAS CONTINUED INTO THE 2026 SEASON, WITH NEW AWARENESS INITIATIVES LAUNCHING AT SONOMA RACEWAY. THE 2025 WARRIOR WALK WAS A RECORD-BREAKING AWARENESS AND FUNDRAISING CAMPAIGN, RAISING MORE THAN 25,000 IN JUST TWO WEEKS AND ATTRACTING THE HIGHEST NUMBER OF FIRST-TIME DONORS IN THE PROGRAM'S HISTORY. PARTICIPANTS ACROSS THE COUNTRY WALKED, RAN, AND ENGAGED THEIR COMMUNITIES TO INCREASE AWARENESS OF RELAPSING POLYCHONDRITIS (RP) AND SUPPORT CRITICAL RESEARCH EFFORTS. A HIGHLIGHT OF THE CAMPAIGN TOOK PLACE AT THE INDIANAPOLIS MOTOR SPEEDWAY, WHERE DRIVERS, CREW MEMBERS, AND FANS ATTENDING A MCLAREN TROPHY AMERICA EVENT JOINED TOGETHER TO WALK A LAP AROUND THE ICONIC TRACK.

RESEARCHERS ARE ALSO COMPARING MULTIPLE DISEASE ACTIVITY MEASUREMENT TOOLS, INCLUDING THE RP DISEASE ACTIVITY INDEX (RPDAI), TO DETERMINE THE MOST EFFECTIVE WAY TO ASSESS DISEASE ACTIVITY IN FUTURE THERAPEUTIC TRIALS. THE PROGRAM FURTHER EXPANDED THE RADAR IMMUNE-PROFILING STUDY TO MORE THAN 400 PATIENT SAMPLES COLLECTED ACROSS MULTIPLE TIME POINTS, CREATING A UNIQUE RESOURCE FOR IDENTIFYING DISEASE BIOMARKERS AND THERAPEUTIC TARGETS THAT MAY ULTIMATELY SUPPORT PRECISION MEDICINE APPROACHES FOR RP. THE FOUNDATION ALSO HELPED STRENGTHEN NATIONAL AND INTERNATIONAL RESEARCH COLLABORATIONS, INCLUDING ONGOING PARTNERSHIP WITH THE NATIONAL INSTITUTES OF HEALTH AND NEW COLLABORATIONS WITH LEADING RHEUMATOLOGY RESEARCHERS IN BEIJING, CHINA, TO EXPAND PARTICIPATION IN BOTH THE LONGITUDINAL STUDY AND PROSPECT-RP.
