Conditions

End Stage Liver DIsease
Interventions
Device: VitaSmart Liver Machine Perfusion System
Other: Static cold storage
Registration Number
NCT05045794
Lead Sponsor
Bridge to Life Ltd.
Brief Summary

This is a prospective, multi-center, controlled, randomized, pivotal study to evaluate the safety and effectiveness of the VitaSmart Liver Machine Perfusion System by comparing clinical outcomes in patients undergoing liver transplantation with ex-vivo liver preservation using static cold storage (SCS) followed by hypothermic oxygenated machine perfusion (HOPE) versus SCS only.

Detailed Description

Patients on the UNOS waiting list for liver transplantation who have been consented, meet study eligibility criteria and are matched to a liver allograft from donation after brain death (DBD) or donation after circulatory death (DCD) that meet the extended risk eligibility criteria will be randomized 1:1 to SCS followed by HOPE (HOPE arm) or to SCS only (SCS arm). The objective of the study is to demonstrate the safety and effectiveness of the VitaSmart Liver Machine by comparing endpoints between the HOPE and SCS arms.

Following transplantation, patients will be monitored daily (labs, adverse events, medications/procedures) while inpatient, and then additionally on Days 14 and 30 and Months 3, 6 and 12. The primary efficacy endpoint of early allograft dysfunction (EAD) rate will be assessed between HOPE and control using a non-inferiority design. An interim analysis is planned after approximately 70% of patients have been completed primary endpoint data collection to assess for early study completion based on non-inferiority or superiority.
