About this study

Official title: Potential Role of Sodium Glucose Cotransporter 2 Inhibitors in the Treatment of Ascites in Cirrhotic Patients

The goal of this observational study is to test the efficacy of glyphozines (SGLT-2 inhibitors) in the control of ascites in patients with liver cirrhosis in class A6-B9, according to the Child-Pugh classification, and type 2 diabetes mellitus. The investigators will compare patients belonging to the intervention group (A), who will be given SGLT-2 inhibitors according to diabetology indications in addition to standard medical therapy for 6, with patients of the control group (B), who will, instead, continue with the standard medical therapy for 6 months. Standard medical therapy will include dietary sodium restriction, treatment with diuretics (furosemide and spironolactone), hypoglycemic therapy (metformin, insulin, or both) and other supportive care.

The main questions aims of this study are:

  1. Compare the efficacy and safety of a therapeutic approach based on the administration of SGLT-2 inhibitors in addition to optimal medical therapy (MRA and loop diuretic) compared to traditional diuretic therapy only, in cirrhotic patients with saline retention and diabetes.
  2. Demonstrate better control of the glycemic profile in cirrhotic diabetic patients using SGLT-2 inhibitors.
Read the detailed description

Background The occurrence of ascites and saline retention is the most common complication in patients affected by liver cirrhosis and it is associated with poor prognosis.

It is well-known that in liver cirrhosis the underlying pathogenetic events responsible of ascites are portal hypertension and splanchnic vasodilation. These mechanisms reduce the effective circulating blood volume, triggering counter-regulatory systems such as the sympathetic nervous system (SNS) and the renin-angiotensin-aldosterone system (RAAS), that leading to renal sodium and water retention.

Therefore, considering pathogenetic knowledge, the cornerstones of ascites treatment are sodium restriction and drugs such as mineralocorticoid receptor antagonists (MRA) and loop diuretics, reserving more invasive techniques, like paracentesis with administration of human albumin, for more severe patients with grade 3 ascites unresponsive to diuretics. However, even though diuretics have proven to be among the most efficient drugs in controlling ascites, patients with liver cirrhosis and ascites treated with diuretics develop adverse drug reactions in 20-40% of cases.

One of the most common comorbidities of liver cirrhosis is type-2 diabetes mellitus (DM2), which affects approximately one-third of cirrhotic patients. The connection between liver cirrhosis and DM2 is complex. DM2 can be a secondary effect or, conversely, a casual factor of liver dysfunction.

Sodium glucose cotransporter 2 inhibitors (SGLT-2i) are a relatively new class of drugs for the management of type-2 diabetes mellitus. They inhibit the reabsorption of sodium and glucose in the proximal convoluted tubule of the nephron, leading to a significant natriuresis and have proven to be effective and safe drugs for the control of the glycemic profile in patients with liver dysfunction.

In recently published case reports, SGLT-2i have also proven to be safe and effective in controlling the glycemic profile in patients with liver dysfunction. In these patients, in addition to better control the glycemic profile, they led to saline retention improvement and to weight loss, without inducing encephalopathy or acute kidney injury. Other studies have hypothesized that, similarly to the previously demonstrated beneficial effect of glyphozines in patients with acute heart failure, SGLT-2i may also lead to the improvement of complicated liver cirrhosis acting as "neuromodulators", suppressing the RAAS axis and inducing better mobilization of ascites and reduction of saline retention.

Currently, there are no randomized controlled trials supporting these evidences.

In this observational study the investigators intend to evaluate the efficacy and safety of SGLT-2i in cirrhotic and diabetic patients with saline retention.

Aims

  • Comparing the efficacy and safety of a therapeutic approach based on the administration of SGLT-2i in addition to optimal medical therapy (MRA and loop diuretic) compared to traditional diuretic therapy only, in cirrhotic patients with saline retention and diabetes.
  • Demonstrating better control of the glycemic profile in cirrhotic diabetic patients using SGLT-2i.

Sample and study design Our study will be a clinical, prospective, observational multicenter study. The investigators will enroll subjects with complicated liver cirrhosis and type II diabetes mellitus consecutively, in two centers: Internal Medicine Unit of the "Policlinico Paolo Giaccone", University Hospital of Palermo, Italy and Internal Medicine Unit of the "Ospedali Riuniti Villa Sofia- Cervello" Hospital of Palermo, Italy.

Sample size The sample size is difficult to determine as there are no studies that have evaluated the efficacy of SGLT-2i treatment in addition to diuretic therapy in the patient with liver cirrhosis and saline retention. To date, there are only a few case reports in the literature that have demonstrated its effectiveness. Considering the prospective and pilot nature of this study the investigators decided to enroll at least 40 patients.

Study design and outcome evaluation Our project has been approved by the ethics committee of the University Hospital of Palermo.

Patients enrolled on the basis of the inclusion and exclusion criteria and who agreed to enter the study, after signing the informed consent, will be assigned to intervention group (group A) or control group (group B).

Patients belonging to the intervention group (A) will be given SGLT-2 inhibitors, according diabetology indications, in addition to standard medical therapy for 6 months; the patients of the control group (B) will instead continue with the only standard medical therapy for 6 months, according diabetology indications.

Standard medical therapy will include dietary sodium restriction, treatment with diuretics (furosemide and spironolactone), hypoglycemic therapy (metformin, insulin, or both) and other supportive care. Patients taking non-selective beta-blockers will continue to do.

Patients in group A and group B will be evaluated for specific clinical and laboratory parameters before the start of the study (T0) and they will subsequently be evaluated again at 4 weeks, 3 months and 6 months (T1, T2, T3).

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?

Ascites control (time frame: Day 0, 4 weeks, 3 months, 6 months). The study lists 3 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 NCT05999773, which also lists 9 linked publications.

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 1 May 2026.
