Chicago was a success! 💫

The IRIS team just wrapped up an incredible week at ACR Convergence 2025, and we couldn’t be prouder! From connecting with brilliant minds to sharing groundbreaking science, this year was one for the books.

🔥 Dr. Guillermo J. Valenzuela was the hot topic at the meeting, leading the conversation on cell therapy and the RESET RA trial during his podium poster presentation ( #1675). His work continues to push the boundaries of what’s possible in rheumatology.

✨ So many opportunities ahead, so many new trials launching, and so much innovative work driving Cylindar forward, empowering research sites, CROs, and sponsors alike.

We’re energized, inspired, and ready for what’s next.
Here are some moments from an unforgettable week in Chicago! 📸💜
