About this study

Official title: Effects of Metformin on Hepatic Venous Pressure Gradient in Patients With Cirrhosis and Portal Hypertension - A Randomized Placebo-controlled Study

Portal hypertension (PHT) is defined by an elevated pressure gradient between the portal vein and the hepatic veins ≥ 5 mm Hg, and is the main vector of complications in cirrhosis.

When the hepatic venous pressure gradient (HVPG) is ≥ 10 mm Hg, it is considered as a " clinically significant PHT ": ascites and oesophageal varices (EV) may occur.

Read more

Above 12 mm Hg, there is a risk of variceal bleeding. Carvedilol, a non-selective beta-blocker (NSBB), is recommended in all the patients with cirrhosis and clinically significant PHT in order to prevent decompensation of cirrhosis.

Nevertheless, 40 % of patients are NSBB non-responders, i.e. they do not show a significant decrease in HVPG. In addition, NSBB responders treated for primary prophylaxis have an incidence of variceal bleeding of approximately 10% per year, with a six-week mortality of 20%. Therefore, there is an unmet need for PHT in patients with cirrhosis who do not respond to NSBB, and also for an increase in efficacy in responders. In a randomised pilot study, Rittig et al. observed a mean change in HVPG of -2,9 mm Hg in 16 patients with cirrhosis and HVPG ≥ 12 mm Hg, not treated with NSBB, 90 minutes after ingestion of 1000 mg metformin.

The study will be a prospective, national, multicentre, phase II, superiority comparative randomized (1:1) simple-blinded clinical trial with two parallel arms: metformin versus placebo.

The main objective is to evaluate the effect of metformin versus placebo during 28 days on HVPG, in patients with cirrhosis and a HVPG ≥ 12 mm Hg already treated with carvedilol.

Subjects randomized in the metformin group or placebo group will receive metformin ou placebo, one pill of 500 mg per os twice a day (one in the morning and one in the evening, during or at the end of the meal) for 28 days.

The main objective is to evaluate the effect of metformin versus placebo during 28 days on HVPG, in patients with cirrhosis and a HVPG ≥ 12 mm Hg already treated with carvedilol.

There are several secondary objectives in this research listed below:

  • evaluate the safety and tolerability of metformin in patients with cirrhosis and a HVPG ≥ 12 mm Hg
  • evaluate the rate of change in HVPG after 28 days of treatment
  • evaluate the rate of patients with a clinically significant improvement in HVPG
  • assess the change in systemic haemodynamics after 28 days of treatment
  • assess the change in liver steatosis after 28 days of treatment
  • assess the performance of liver and spleen stiffness by vibration-controlled transient elastography (VCTE) using FibroScan® (Echosens, Paris, France) to estimate the haemodynamic response to the treatment
  • assess the performance of liver and spleen stiffness by 2D-shear wave elastography using Aixplorer® (SuperSonic Imagine, Aix-en-Provence, France) to estimate the haemodynamic response to the treatment
  • assess the effect of metformin on systemic inflammation, coagulation, hepatocyte stress, and endothelial function.

Subjects randomized in the metformin group or placebo group will receive metformin ou placebo, one pill of 500 mg per os twice a day (one in the morning and one in the evening, during or at the end of the meal) for 28 days.

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 26 inclusion and 26 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: looking for participants now, as of the sponsor's last update on 13 Apr 2025. 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 France. 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 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.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

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?

Contact LUCILE MOGA (01 71 11 46 69 ext. +33, lucile.moga@aphp.fr), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

effect of metformin versus placebo during 28 days on HVPG, in patients with cirrhosis and a HVPG ≥ 12 mm Hg already treated with carvedilol. (time frame: after 28 days of treatment). 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 NCT06687265, 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 13 Apr 2025.
