Long-term Outcomes After Prolonged Dual Hypothermic Oxygenated Machine Perfusion of Donor Livers (DHOPEPROLONG) (DHOPEPROLONG)

May 19, 2024 updated by: University Medical Center Groningen

Prospective Observational Study to Investigate Long-term Outcomes After Prolonged Dual Hypothermic Oxygenated Machine Perfusion of Human Donor Livers (DHOPEPROLONG)

End-ischemic dual hypothermic oxygenated machine perfusion (DHOPE) 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. End-ischemic DHOPE can be used to prolong donor liver preservation time for up to 24 hours. According to IDEAL-D (Idea, Development, Exploration, Assessment, Long term study-Framework for Devices), scientific evidence for prolonged DHOPE has currently reached stage 3. Assessment of long-term outcomes after prolonged DHOPE preservation based on real-world data (i.e., IDEAL-D stage 4) is currently still lacking.

Study Overview

Status

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The aim of this study is to assess long-term outcomes after transplantation of donor livers preserved by prolonged hypothermic oxygenated machine perfusion (DHOPE-PRO).

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.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Death-censored graft survival
Time Frame: Up to 5-years
Death-censored graft survival, assessed by survival analysis methods.
Up to 5-years

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
