Experimental liver drug shows early promise but trial cut short
NCT ID NCT05900050
First seen Jun 26, 2026 · Last updated Jul 24, 2026 · Updated 3 times
Summary
This early study tested a drug called VS-01 in 15 adults with acute-on-chronic liver failure (a sudden worsening of liver function) and fluid buildup in the belly. Participants received either VS-01 plus standard care or standard care alone. The trial was terminated early, so we have limited data on whether VS-01 helps improve survival or liver function.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- VS-01 (a liposomal drug given into the abdominal cavity)
- What this could lead to
- If successful, VS-01 could offer a new way to manage acute-on-chronic liver failure and reduce short-term mortality.
- What could go wrong
- This is a very early, small study (15 people) that was terminated, so results are limited. The drug is experimental and may not improve outcomes or could cause side effects.

Inclusion Criteria: 1. Patients with ACLF Grade 1, 2, or 3a according to European Association for the Study of the Liver (EASL)-CLIF criteria; 2. Onset of ACLF not more than 14 days before Baseline (BL); 3. Presence of ascites requiring diagnostic or therapeutic paracentesis; 4. Patients with dry body weight ≥40 and \<140 kg; 5. Written informed consent obtained prior to the start of any study-related procedures. Exclusion Criteria: 1. Presence of any of the following organ failure(s) as per the EASL-CLIF criteria and/or adapted from CLIF-C Organ Failure (CLIF-C OF)/CLIF- Sequential Organ Failure Assessment (CLIF-SOFA) scores: 1. Respiratory failure necessitating invasive mechanical ventilation; 2. Coagulation failure (INR \> 3.2 or platelet count ≤20 x 109/L); 3. Severe cardiovascular failure requiring the use of high dose vasopressors; 2. ACLF grade 3b: Presence of four or more organ failures as per EASL CLIF criteria; 3. Presence of spontaneous or secondary bacterial peritonitis; 4. Presence of uncontrolled severe infection(with hemodynamic instability or shock); 5. Poorly controlled seizure disorder; 6. Patients with history of upper gastro-intestinal bleeding over the past 7 days prior to BL, acute bleeding or bleeding upon paracentesis at screening (SCR) or BL; 7. Contraindication for paracentesis; 8. Coagulation disorders such as disseminated intravascular coagulation or hemophilia; 9. Potential or known hypersensitivity to liposomes; 10.
