About this study

GUARDIAN-Liver is a post-market, observational registry of adult and pediatric liver transplant recipient patients whose donor liver was preserved and transported within the LIVERguard. The data is being collected retrospectively from medical records of patients already transplanted before the initiation of the registry and any new patients who meet the eligibility criteria.

About 1000 male and female subjects meeting the study inclusion and exclusion criteria will be enrolled into the study at about 20 clinical sites.

Candidates that fit the eligibility criteria and have had their donor liver transported with a Paragonix product or a standard of care method can be enrolled. The baseline characteristics and outcomes of the two groups will be compared.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Donor and donor liver matched to the recipient based upon institutional medical practice
  • Registered male or female primary liver transplant candidates

Exclusion criteria

  • Donor and donor liver that do not meet institutional clinical requirements for transplantation
  • Living donors
  • Pediatric recipients (under 18)

Treatment and study plan

LIVERguard

Device

The LIVERguard is an FDA cleared and is a CE-marked medical device intended to be used for the static hypothermic preservation of livers during transportation and eventual transplantation into a recipient using cold storage solutions indicated for use with the liver. The intended organ storage time for the LIVERguard is up to 16 hours.

Primary outcomes

  1. Graft Failure

    Time frame: Post-transplant through 1 year post

    The percentage of subjects in each cohort who develop graft failure post-transplant

  2. Early allograft dysfunction

    Time frame: 7 days post transplant

    The percentage of subjects in each cohort who early allograft failure post-transplant

  3. Rejection

    Time frame: Post-transplant through 1 year post

    The percentage of subjects in each cohort who experience rejection post-transplant

  4. Primary Non-function

    Time frame: Post transplant to 7 days post-transplant

    The percentage of subjects in each cohort who experience primary non-function post-transplant

  5. Survival

    Time frame: Transplant through 1 year post-transplant

    The percentage of subjects in each cohort who survive through 1 year post-transplant

  6. Length of Stay

    Time frame: 1 year

    How many days the patient stays in the hospital post-transplant

  7. Length of ICU stay

    Time frame: 1 year

    How many days the patient stayed in the ICU post-transplant

Secondary outcomes

  1. Hospitalizations

    Time frame: post-transplant through 1 year
