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).
- Being tested

Questions about this trial
What is this clinical trial studying?
An observational study of Organ Preservation and Liver Transplantation, run by University Medical Center Groningen at 2 sites in 2 countries.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 22 Apr 2024. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites in Netherlands, Switzerland. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
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?
Death-censored graft survival, assessed by survival analysis methods (time frame: Up to 5-years). It is what the study was designed to measure, not a finding.
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.
