RESTORE Declined Livers Study

Description

This is a prospective, non-randomized, clinical trial of discarded liver transplants that have received normothermic machine perfusion (NMP), compared with standard cold preservation liver transplants. The discarded livers rejected by all other centers and meeting pre-NMP eligibility criteria will receive NMP using the OrganOx® metra device. The NMP-treated liver that meets the viability criteria will be transplanted to patients who are eligible and consented to the study. Liver transplant outcomes will be ascertained during 12 months post-transplantation. The results of the trial will be compared with those of contemporary comparison groups of patients who received the standard criteria donor liver transplantation.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

For general information about clinical research, read Learn About Studies.

Eligibility Criteria

  • * DCD donor aged 6 years or greater and liver weight between 1 kg and 3.4 kg, with functional warm ischemic time (defined as the period between the systolic blood pressure less than 60 mmHg to the time of commencing donor aortic perfusion) in DCD donors less than 40 minutes
  • * DCD asystolic warm ischemia time (from heartbeat stopping to initiation of cold flush) less than 15 minutes
  • * DBD donor aged 6 years or greater and liver weight between 1 kg and 3.4 kg, with less than 8 hours cold ischemia time and DCD livers with less than 7 hours cold ischemia time (defined as the interim from initiation of donor in vivo cold organ preservation to removal of the liver graft from cold storage)
  • * 'Rapid Recovery' donors for liver procurement, meeting the above criteria
  • * Suboptimal in situ flush
  • * DBD or DCD donor less than 6 years old
  • * DCD grafts with donor functional warm ischemic time (defined as the period between the systolic blood pressure less than 60 mmHg to the time of commencing donor aortic perfusion) greater than or equal to 40 minutes
  • * DCD asystolic warm ischemia time (from heartbeat stopping to initiation of cold flush) greater than or equal to 15 minutes
  • * DBD livers with cold ischemia time greater than or equal to 8 hours and DCD livers with greater than or equal to 7 hours cold ischemia time
  • * Donor serum bilirubin greater than or equal to 5 mg/dL
  • * Liver weight less than 1 kg or greater than or equal to 3.5 kg
  • * Grafts from patients with HIV infection
  • * Cirrhotic livers
  • * Livers with bridging fibrosis
