About this study

Official title: Assessment of Long-term Outcomes After Transplantation of Donor Livers Preserved by Hypothermic Oxygenated Machine Perfusion (HOPE): a Retrospective Cohort Analysis of Real-world Data (IDEAL-D Stage 4)

End-ischemic hypothermic oxygenated machine perfusion (HOPE) of human donor livers mitigates ischemia-reperfusion injury, resulting in a reduction of post-reperfusion syndrome, early allograft dysfunction and biliary complications, when compared with static cold storage. According to IDEAL-D (Idea, Development, Exploration, Assessment, Long term study-Framework for Devices), with several published randomized controlled trials on short-to-medium term outcomes, scientific evidence for HOPE has currently reached stage 3. Assessment of long-term outcomes after HOPE preservation based on real-world data (i.e., IDEAL-D stage 4) is currently still lacking. Therefore, we aim to conduct an international, multi-center, retrospective, observational cohort study to assess long-term outcomes after transplantation of donor livers preserved by hypothermic oxygenated machine perfusion (HOPE).

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Death-censored graft survival, assessed by survival analysis methods

    Defined as time from liver transplantation until re-transplantation or death due to graft dysfunction

    Measured: Up to 5-years

Secondary outcomes (11)
  1. Overall graft survival

    Defined as time from liver transplantation until re-transplantation or all-cause death

    Measured: Up to 5-years

  2. Overall patient survival

    Defined as time from liver transplantation until all-cause death

    Measured: Up to 5-years

  3. Arterial and biliary complication-free survival (ABCFS)

    Defined as time from liver transplantation until occurrence of an arterial or biliary complication of Dindo-Clavien grade ≥3, dated at the time of interventional, endoscopic, or surgical treatment required to correct it (Savier E, De Rycke Y, Lim C, et al. Novel Composite Endpoint for Assessing Outcomes in Liver Transplantation: Arterial and Biliary Complication-Free Survival. Liver Transpl. 2022;28(1):75-87. doi:10.1002/lt.26269)

    Measured: Up to 5-years

  4. Incidence of biliary complications

    Defined as a composite of:

    • Non-anastomotic biliary strictures: any irregularity or narrowing of the lumen of the intrahepatic or extrahepatic donor bile ducts, excluding the biliary anastomosis, diagnosed with the use of cholangiography in combination with clinical symptoms (e.g., jaundice or cholangitis) or an elevation of cholestatic laboratory variables, in the presence of a patent hepatic artery
    • Anastomotic biliary strictures: strictures occurring at the anastomosis of donor choledochal duct and recipient choledochal duct or jejunal Roux-limb
    • Biliary leakage: fluid with an elevated (>3x serum) bilirubin level in the abdominal drain or intra-abdominal fluid on or after post-operative day 3 or the need for radiological intervention (i.e. interventional drainage) owing to biliary collections or re-laparotomy due to biliary peritonitis

    Measured: Up to 5-years

  5. Incidence of vascular complications

    Defined as a composite of:

    • Hepatic arterial thrombosis: radiologically or surgically proven thrombosis of the hepatic artery
    • Portal vein thrombosis: radiologically or surgically proven thrombosis of the portal vein
    • Venous outflow tract obstruction: radiologically or surgically proven thrombosis of the main hepatic veins or the inferior vena cava

    Measured: Up to 5-years

Hepatology. 2000;31(3):792-799. doi:10.1002/hep.510310337)

    Measured: Up to 5-years

  8. Incidence of re-transplantation

    Defined as proportion of patients who underwent liver re-transplantation for any cause

    Measured: Up to 5-years

  9. Incidence of recurrence of primary disease (including recurrence of malignancies)

    Defined as histological or radiologically confirmed recurrence

    Measured: Up to 5-years

  10. Incidence of new-onset chronic kidney disease

    Defined as renal impairment (kidney morphology, pathology, imaging, blood or urine composition abnormalities) persisting for >3 months with or without eGFR decrease, and/or eGFR <60 for >3 months with or without renal impairment (Levey AS, Eckardt K-U, Tsukamoto Y, et al. Definition and Classification of Chronic Kidney Disease: A Position Statement from Kidney Disease: Improving Global Outcomes (KDIGO). Kidney Int. 2005 Jun;67(6):2089-100. doi: 10.1111/j.1523-1755.2005.00365.x)

    Measured: Up to 5-years

  11. Incidence of new-onset diabetes after transplantation

    Defined as symptoms of diabetes plus casual plasma glucose levels ≥200 mg/dL (11.1 mmol/L) or fasting plasma glucose ≥126 mg/dL (7.0 mmol/L) or 2 hours plasma glucose ≥200 mg/dL (11.1 mmol/L during an oral glucose tolerance testing (Davidson J, Wilkinson A, Dantal J, et al. New-onset diabetes after transplantation: 2003 International consensus guidelines. Proceedings of an international expert panel meeting. Barcelona, Spain, 19 February 2003. Transplantation. 2003;75(10 Suppl):SS3-24. doi:10.1097/01.TP.0000069952.49242.3E)

    Measured: Up to 5-years

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05520320, which also lists 3 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 22 Apr 2024.
