A machine that keeps donor livers alive outside the body — could it transform transplantation?

NCT ID NCT05045794

First seen Jul 22, 2026 · Last updated Jul 23, 2026 · Updated 1 time

Summary

This trial tests whether a device called VitaSmart, which pumps cold, oxygenated preservation fluid through a donor liver before transplant, can reduce early organ dysfunction and improve survival compared with the usual method of simply storing the liver on ice. About 228 adults with end-stage liver disease awaiting a transplant will be randomly assigned to receive a liver preserved either by standard cold storage alone or by cold storage followed by VitaSmart machine perfusion. The study tracks early graft function, graft survival, and patient survival up to 12 months.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
VitaSmart Liver Machine Perfusion System — a device that pumps cold, oxygenated preservation fluid through a donor liver before transplantation
What this could lead to
If it works, this could reduce early liver damage after transplant and improve graft survival, potentially expanding the pool of usable donor livers.
What could go wrong
This is a pivotal trial, but machine perfusion adds complexity and cost; it may not meaningfully improve outcomes over standard cold storage, and device-related complications are possible.
