About this study

This study is to investigate MER receptor tyrosine kinase (MERTK) signalling cascade on monocytes and tissue macrophages in respect to innate immune function of the cells in patients with cirrhosis at different stages of disease (Child A, B, C, acute decompensation, acute-on-chronic liver failure (ACLF)) and in comparison to patients with acute liver failure and to healthy controls.

Read the detailed description

MER receptor tyrosine kinase (MERTK) signalling cascade becomes activated on monocytes/macrophages during disease progression of liver cirrhosis from Child Pugh A to B/C, corresponding to early stages of decompensation, and before the receptor expression is increased. Factors involved in activation of the MERTK signalling cascade might be microbial products such as bacterial deoxyribonucleic acid (DNA) and other toll-like receptor (TLR)-ligands, MERTK ligands and cytokines, as shown elevated in cirrhotic patients.

Given the observation that MERTK levels peak on the day of admission with organ failure and decrease in patients surviving the episode of acute-on-chronic liver failure (ACLF), MERTK Inhibition at a time during progression of cirrhosis but before manifestation of acute decompensation with no cirrhosis (AD) or ACLF might prevent infectious complications, decompensation and improve survival in patients with cirrhosis.

This study is to investigate MER receptor tyrosine kinase (MERTK) signalling cascade on monocytes and tissue macrophages in respect to innate immune function of the cells in patients with cirrhosis at different stages of disease (Child A, B, C, acute decompensation, acute-on-chronic liver failure (ACLF)) and in comparison to patients with acute liver failure and to healthy controls.

What participants receive

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

  • blood sampling for research purposeOther

    blood sampling for research purpose (about 30ml) taken by venepuncture or from intravenous catheters if already in place

  • clinical data collectionOther

    clinical data collection in order to document the stage of disease, the presence of infection and existing complications of cirrhosis (ascites, hepatic encephalopathy, renal dysfunction, pulmonary dysfunction) and concomitant disease. These data will be collected for clinical reasons as highly important in the context of patients with cirrhosis and possible decompensation or liver failure and will therefore not require additional time

  • Health-related QuestionnairesOther

    Health-related Questionnaires (Questionnaire_CLD) regarding sleep characteristics (Pittsburgh sleep Quality index, PSQI), daytime sleepiness (Epworth sleepiness scale, ESS), anxiety and depression (Hospital Anxiety and Depression Scale, HADS) and quality of life (EQ-5D-5L)

  • Sampling other biological materials (e.g. liver biopsies, liver resections, ascites, urine, gut biopsies)Other

    Other biological material (e.g. liver biopsies, liver resections, ascites, urine, gut biopsies) will only be investigated if sampled for clinical reasons and if excessive material is available that is not needed for clinical purpose.

Questions about this trial

What is this clinical trial studying?

An observational study of Liver Disease and Cirrhosis of the Liver, run by University Hospital, Basel, Switzerland at 4 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 3 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 25 Jun 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 sites in Switzerland, United Kingdom. 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?

Change in MERTK signalling cascade on monocytes (time frame: days 1 (Baseline), 3, 7, and 14; then followed 6-monthly for up to 36 months). 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 25 Jun 2024.
