About this study

Early postoperative extracorporal liver support therapy (ELS) as a tool to manage post hepatectomy liver failure (PLF).

Post-operative liver failure (PLF) has been identified as a major risk factor leading to increased morbidity and mortality. The incidence of PLF varies largely between 0-30%, and may be accounted for the main reason of postoperative mortality related to liver surgery (reported figures ranging from 18 to 75 %).

Currently, there are only a few treatment options for PLF, mainly restricted to the treatment of complications like bile leakage, infections as well as the prevention of further liver damage caused by e.g. thrombosis or haemorrhage as well as administration of liver toxic drugs. Recently the international study group on liver surgery (ISGLS) published criteria for a new definition of PLF which will greatly facilitate the comparison of results from future studies on a variety of aspects on liver failure.

ELS by using the Molecular Adsorbent Recirculating System (MARS) is based on a modified haemodialysis that allows the removal of water-soluble and protein bound toxins over an albumin-coated high flux membrane against recycled exogenous albumin. Thus, MARS can support the compromised detoxification capacity of the liver as well as improve physiological parameters. This would offer the potential for temporary support for the harmed liver after liver resection allowing for a more uneventful recovery.

For obvious reasons previous reports contain few patients, present heterogonous treatment groups and all suffer from lack of standardized treatment protocols. Few if any surviving patients, thus providing no evidence to encourage ELS as a possible treatment option for patients suffering of PLF. However, studies with defined patient populations and treatments according to a predefined standardised treatment protocol are warranted.

Primary issues to be addressed:

  1. Can ELS be applied in an early phase of PLF?
  2. Is ELS safe and feasible for the treatment of PLF when practised according to a predefined protocol?

Secondary issues to be addressed:

  1. The development of predictive laboratory-chemical markers of liver failure
  2. Indirect measures of portal flow and portal pressure
  3. Indocyanine green clearance (ICG) under ELS treatment
  4. Clearance of toxic products as assessed in aliquots taken from the dialysate

What is being measured

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

  1. Number of PLF patients who develop serious adverse events during ELS according to SOFA scores and Westhaven criteria

    At least five sessions of Mars. SOFA (score 1-4).

    Measured: First two weeks postoperatively after major hepatectomy

  2. Number of PLF patients who develop serious adverse events during ELS

    At least five sessions of Mars. Westhaven (criteria 1-4)

    Measured: First two weeks postoperatively after major hepatectomy

Secondary outcomes (4)
  1. The predictive value of liver enzymes and bilirubin changes as marker of liver failure

    At least five sessions of Mars. Liver enzymes measured( liver transaminases microkat/L ), bilirubin (mmol/L)

    Measured: First two weeks postoperatively after major hepatectomy

  2. Portal flow (ml/minute) before and during ELS

    At least five sessions of Mars

    Measured: First two weeks postoperatively after major hepatectomy

  3. To assess liver function by use of Indocyanine green clearance (ICG)(% clearance/unit time) under ELS treatment

    At least five sessions of Mars

    Measured: First two weeks postoperatively after major hepatectomy

  4. Portal pressure (cmH2O) before and during ELS

    At least five sessions of Mars

    Measured: First two weeks postoperatively after major hepatectomy

Questions about this trial

What is this clinical trial studying?

A study testing Extracorporeal liver support therapy (ELS) in people with Post Hepatectomy Liver Failure, run by Karolinska University Hospital at 1 site in Sweden.

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 3 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 4 Jan 2019. 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 Sweden. 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?

Number of PLF patients who develop serious adverse events during ELS according to SOFA scores and Westhaven criteria (time frame: First two weeks postoperatively after major hepatectomy). 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?

On the ClinicalTrials.gov record for NCT03011424, which also lists 1 linked publication.

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 4 Jan 2019.
