About this study
Official title: Allopurinol Impact on Cirrhosis Related Complications
The study aims to compare the potential benefit of allopurinol in reducing the risk of developing cirrhosis-related complications, delaying the onset of hepatocellular carcinoma, and improving survival. Furthermore, the study aims to evaluate their impact on parents' related quality of life
Read the detailed description
Cirrhosis is the late stage of liver damage and possess two phases: a compensated phase with favorable prognosis and a decompensated phase with high mortality rate.The shift from compensated to decompensated cirrhosis is characterized by the onset of complications, including ascites, hepatic encephalopathy (HE), variceal bleeding, and spontaneous bacterial peritonitis (SBP) which are associated with substantial morbidity and negative Impact on quality of life (QOL).
The gut microbiota plays an important role in cirrhosis and development of cirrhosis-related complications.
Indeed, translocation of endotoxins is increased in patients with cirrhosis and patients with more severe cirrhosis (i.e. Patients with decompensated cirrhosis, hospitalized patients) had significantly greater serum endotoxin concentrations that mediate complications of cirrhosis.
Intestinal permeability plays a role in the development of bacterial translocation and may be involved in the development of complications of cirrhosis. This 'leaky gut' phenomenon increases with the degree of liver failure and is particularly prominent in patients with cirrhosis who have experienced severe septic complications and has been implicated in the hepatic production of endotoxin-associated proinflammatory cytokines.
Intestinal mucosa alterations at the subcellular level have been reported in experimental cirrhosis, in relation to an increased oxidative stress due to overactivity in the enzyme xanthine oxidase.
Allopurinol, a competitive xanthine oxidase inhibitor, reduces oxidative stress and attenuates bacterial translocation in portal hypertensive animals, suggesting that the damaging effects of oxygen-derived free radicals and peroxidation on mucosal cells may be counteracted by a free radical scavenger.
In 2007, a pilot study demonstrated that allopurinol in patients with cirrhosis is associated with a significant reduction in oxidative stress but no effect on intestinal permeability and inflammatory markers. The study duration was only 10 days and therefore another study with a long period of time is essential.

Questions about this trial
What is this clinical trial studying?
A Phase 2/3 study testing Allopurinol 300 MG in people with Cirrhosis, run by Tanta University at 1 site in Egypt.
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 4 Nov 2026. 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 Egypt. 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. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this combined phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
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?
morbidities (time frame: 6 moths). 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 NCT05545670, 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 Nov 2026.
