2026 holds great promise thanks to the clinicians, researchers and funders who continue to advocate for innovative microbiome therapeutics for patients with Clostridioides difficile, an insidious disease of the gut. Together, we will continue to advance microbiome research, close the treatment gap for the most vulnerable and assure no patient is left behind.

The Peggy Lillis Foundation ’s 16th Annual Gala brought out the stars for C diff patients. Dr. Stacy Kahn, attending Physician at Boston Children’s Hospital (third from left) was honored with a Leadership Award for her many firsts. She directed the nation’s first pediatric f***l microbiota transplant (or FMT) program, created the first national pediatric FMT registry, and performed the very first FMT for a child. She is joined by (left to right) Liam Lillis, Co-Founder and President of the Peggy Lillis Foundation, OpenBiome Foundation’s CEO Julie Barrett O’Brien and Christian John Lillis, Co-Founder and CEO of the Peggy Lillis Foundation. Dr. Kahn has worked tirelessly with OpenBiome and the Peggy Lillis Foundation to ensure children and medically complex patients retain access to life-changing f***l transplants.

We’re proud to be at , standing shoulder to shoulder with gutsy pioneers, patients, and partners in gut health.

OpenBiome has always believed in the power of being gutsy -taking bold action to serve patients with C. Diff and accelerating the next wave of microbiome breakthroughs.

Let’s make this week about science with a soul.

We’re heading to Digestive Disease Week (DDW) this weekendβ€”and we’re bringing our boldest commitment with us: No C. diff patient left behind.

At OpenBiome, being gutsy means taking action where it matters most: supporting clinicians through the complexities of FMT and regulatory pathways; training hospitals to make in-house FMT accessible and sustainable; and powering a clinical study for patients with severe and fulminant C. diff.

If you're a clinician, researcher, or partner attending β€”and you’re committed to transforming C. diff careβ€”we want to talk.

DM me or comment below if you’d like to connect in San Diego.

Let’s be gutsy, together.
