X-Therma Inc. today announced its inclusion in the special issue of Mediaplanet’s USA Today’s Kidney Health campaign, which launched in conjunction with the American Society of Nephrology’s (ASN) Kidney Week 2025. The feature, titled “Subzero Organ Preservation Is Ready to Transform Transplantation,” highlights how X-Therma’s groundbreaking technology is replacing the critical 24-hour countdown for kidney viability with a 5-day window of hope.
The article details how X-Therma’s core technology, the XT-ViVo® & TimeSeal® organ transport system, is poised to change the world of transplantation. The U.S. Food and Drug Administration (FDA) granted the system Breakthrough Device Designation in late 2021 for preserving human kidneys for up to 120 hours (5 days). This advancement directly addresses the urgent crisis where one person currently dies every hour on the organ waiting list, often because viable kidneys cannot be transplanted within the traditional 24-hour limit.
“The impossible is becoming possible,” said Dr. Xiaoxi (Sofie) Wei, CEO & Co-founder of X-Therma. “Biological time limitations are no longer a given. Our system provides added time for transplantation with the expectation to give patients better health outcomes.”
The campaign, which also headlines NBA Hall of Famer and transplant recipient Alonzo Mourning, serves as a beacon of hope for the more than 107,000 Americans currently waiting for a life-saving organ.
The company notes that the new 5-day transport window ensures that the gift of a donated organ has the best chance of being transplanted, stating: “We are not just engineering preservation. We are engineering hope.”.
X-Therma’s technology development, drawing inspiration from how arctic species survive cold, led to the development of novel biomimetic molecules (peptoids) that prevent ice crystal formation, allowing safe, ice-free subzero preservation. This technology has already been successfully demonstrated both through a transatlantic pig kidney transport on a commercial plane in a passenger seat and by kidney transplants that maintained normal renal function for 200 days post-transplant after 72 hours of ice-free subzero preservation.
