Developing a viability index for machine-perfused livers
Official title: Development of a Liver Viability Index for Transplantation
Run by Massachusetts General Hospital · NCT03694691 · Data updated 2026-11-12
This study is testing a new way to see if discarded livers can be successfully transplanted by using machine technology to check their health before giving them to patients in need of a liver transplant.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates for this study are individuals aged 18-75 who are awaiting a deceased-donor liver transplant.
✕Probably not a fit
Patients who are HIV-1 positive will not benefit from this study due to exclusion criteria.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This study aims to improve the transplantability of discarded liver grafts using machine perfusion technology. By collecting biopsies from livers before and after transplantation, researchers will analyze metabolite and gene expression data to establish a viability index. This index will help determine which machine-perfused livers can be successfully transplanted, potentially increasing the availability of donor organs. The study focuses on patients who are candidates for deceased-donor liver allografts.
Why it matters
Potential benefit: If successful, this study could significantly increase the number of viable livers available for transplantation, improving outcomes for patients with liver cirrhosis.
How similar studies have gone: While machine perfusion technology is being explored in other studies, the development of a specific viability index for liver grafts post-machine perfusion is a novel approach.
