Removing Time from the Equation
X-Therma enables the robust preservation of cells, tissues, organs, and other biologics by leveraging our proprietary peptoid. The peptoid inhibits lethal ice crystals, allowing long-term sub-zero storage of biological materials while maintaining unparalleled functionality and viability.
How it Began
When she was 8 years old, Xiaoxi’s beloved grandfather passed away. If he had received a donor liver, he would have had more time to spend with loved ones.
Xiaoxi has since dedicated her life to finding a solution that increases organ availability. In 2014 she obtained her doctorate in medicinal chemistry from SUNY-Buffalo. Soon after, she established X-Therma to bring her vision of eradicating organ waitlists to life.
Xiaoxi Wei, CEO began her research work for X-Therma at Lawrence Berkeley National Laboratory. She received her first grant awarded to X-Therma. Provisional patent filed.
Only one year later X-Therma had two additional grants in implementation and a team of four. First successful proof of concept for novel preservation of cell lines.
X-Therma now has five grants running simultaneously and filed additional provisional patents.
X-Therma partnered with Johns Hopkins University and Dr. Gerald Brandacher on several grants. X-Therma awarded first patent claim set!
Successful in vivo mouse heart transplant with Johns Hopkins University.
X-Therma survived the Covid-19 pandemic and was able to continue with successful ex vivo organ transplantations.
X-Therma closed an oversubscribed $13M Series A financing led by LOREA AG. The European office was opened.
The FDA designated X-Therma's proprietary organ preservation solution, XT-ViVo®, and TimeSeal® Organ Transport Device, Breakthrough Device status.
