New test may help doctors pick better livers for transplant
NCT ID NCT07315204
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether measuring a substance called FMN in the fluid used to preserve donated livers can predict how well the liver will work after transplant. Researchers will collect samples from 850 liver transplant patients at multiple hospitals. The goal is to see if FMN levels can help doctors avoid using livers that might fail.

Who is studied
Recipients of deceased-donor liver transplant (DCD and DBD) will be recruited from outpatient clinics and inpatient services at the Cleveland Clinic Foundation Main Campus in the department of liver transplant. Patients will undergo their complete liver transplant work-up as directed by the multi-disciplinary selection committee and under the national direction of the United Network for Organ Sharing (UNOS). After completing their work-up, patients are discussed at the Liver Transplant Selection Committee, who must come to a consensus agreement regarding a candidate's eligibility prior to transplant. Each patient undergoing primary liver transplantation alone for end stage liver disease and/or liver tumor is eligible once approved by the committee, because this is an observational study comparing perfusion samples with standard-of-care clinical outcomes. Participating centers in this study will follow the standard procedures of their respective institutions.
