About this study

Official title: Assess Safety and Feasibility of Sequential Hypothermic Oxygenated Machine Perfusion and Normothermic Machine Perfusion to Preserve Extended Criteria Donor Livers for Transplantation

Hypothermic machine perfusion (HMP) has been shown to be beneficial to preserve extended criteria donor (ECD) livers for transplantation. Normothermic machine perfusion (NMP) had the same benefits and also the convenience on liver quality assessment. The investigators proposed to do sequential HMP (1-4 hours) and NMP (1-14 hours) on 18 ECD transplanted human livers by using an institutional-developed perfusion device for liver transplantation.

Read the detailed description

Liver transplantation is a successful therapy on the patients with end-stage liver disease, however is limited by the shortage of donor organs. Donor criteria were expanded in the past decades, however the extended criteria donor (ECD) livers may induce a higher risk of complications. Static cold storage (SCS) is the standard procedure for ex vivo liver preservation for about 4 decades, but has the limitation on preserving ECD livers and especially the inconvenience to evaluate liver quality prior to transplantation. Hypothermic (4-8 Celsius degree) machine perfusion (HMP) and Normothermic (35-37 Celsius degree) machine perfusion (NMP) have been shown to be beneficial to preserve extended criteria donor (ECD) livers respectively. NMP also had the convenience on liver quality assessment. The investigators had an institutional-developed device for liver NMP used on 25 patients with the FDA's IDE approval. In the present study the investigators are proposing to expand the use of the device on sequential HMP (1-4 hours) and NMP (1-14 hours) on 18 ECD transplanted human livers. This will be a single center prospective pilot study. The liver metabolism and hydrodynamics during perfusion will be recorded. The transplant procedure and post-transplant care will follow the clinical standard of care. The follow-up period is 12 months after transplantation. The primary end point will be the rate of patient survival and primary non function (PNF) within 30 days after transplantation, while the secondary end points will be: Early Allograft Dysfunction (EAD), 6 months patient and graft survival, peak liver function tests in the first 7 days after transplantation, surgical outcomes (operative time, transfusion requirement etc.), rate of post-transplant kidney failure, assessment of histological ischemia reperfusion (liver and bile duct), rate of vascular complications, rate of biliary complications, hospital and ICU length of stay, rejection rate, infection rate, the ability to predict function based on "on-pump" viability markers, and the incidence of adverse effect (AE).

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Liver Machine Perfusion (MP) deviceDevice

    Donor livers will have ex vivo continuous perfusion on the institutional-developed Liver MP device. The temperature of liver grafts will be controlled during perfusion.

What is being measured

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

  1. patient survival at 1 month post-transplant

    Patient survival will be recorded at 1 month post transplantation.

    Measured: 1 month post-transplant

  2. graft survival at 1 month post-transplant

    graft survival will be recorded at 1 month post transplantation. The allograft will be considered lost if a patient has a primary non function (PNF), liver re-transplant or in the event of patient death.

    Measured: 1 month post-transplant

Secondary outcomes (10)
  1. rate of post-transplant early allograft dysfunction (EAD)

    EAD is defined as the presence of one or more of the following previously defined postoperative laboratory analyses reflective of liver injury and function: bilirubin ≥10mg/dL on post-operative day (POD) 7, international normalized ratio (INR) ≥1.6 on POD 7, and alanine or aspartate aminotransferases (ALT or AST) >2000 IU/L within the first 7 days.

    Measured: in the first 7 days after transplantation

  2. patient survival at 6 month post-transplant

    patient survival will be recorded at 6 months post transplantation.

    Measured: 6 month post-transplant

  3. graft survival at 6 month post-transplant

    graft survival will be recorded at 6 month post transplantation. The allograft will be considered lost if a patient has a primary non function (PNF), liver re-transplant or in the event of patient death.

    Measured: 6 month post-transplant

  4. Estimated blood loss at transplant surgery

    Estimated blood loss (ml) during transplant surgery

    Measured: during surgery

  5. peak alanine aminotransferases in the first 7 days after transplantation

    peak level (U/L) of alanine aminotransferases in the first 7 days after transplantation

    Measured: in the first 7 days after transplantation

  6. peak aspartate aminotransferases in the first 7 days after transplantation

    peak level (U/L) of aspartate aminotransferases in the first 7 days after transplantation

    Measured: in the first 7 days after transplantation

  7. total bilirubin on post-operative day 7

    total bilirubin (mg/dL) on post-operative day 7

    Measured: on post-operative day 7

  8. international normalized ratio on post-operative day 7

    international normalized ratio on post-operative day 7

    Measured: on post-operative day 7

  9. Hospital length of stay

    Length of stay (days) in the hospital at the time for transplantation

    Measured: up to 36 weeks

  10. ICU length of stay

    Length of stay (days) in ICU at the time after liver transplantation

    Measured: up to 36weeks

Questions about this trial

What is this clinical trial studying?

A study testing Liver Machine Perfusion (MP) device in people with Liver Transplantation, run by Koji Hashimoto at 1 site in United States.

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 4 inclusion and 4 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: under way, not looking for participants, as of the sponsor's last update on 26 Jul 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. 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?

This study is still under way. Results are not available in the source record yet.

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?

patient survival at 1 month post-transplant (time frame: 1 month post-transplant). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 26 Jul 2024.
