Eligibility

Inclusion Criteria:

1. Cirrhotic patients diagnosed by standard clinical criteria, imaging findings and/or histology with any underlying etiology;

2. Cirrhotic patients with ACLF Grade 1 or 2 according to European Association for the Study of the Liver (EASL)-CLIF criteria as described in the EASL-Clinical Practice Guideline on decompensated liver cirrhosis (EASL Clinical Practice Guidelines, 2018);

3. Onset of ACLF not more than 96 h before Screening (SCR);

6. Written informed consent obtained prior to the start of any study-related procedures.

Exclusion Criteria:

1. Patients with acute or sub-acute liver failure without underlying cirrhosis;

2. Presence of the following organ(s) failure(s) as per the EASL definitions and/or adapted from CLIF-C Organ Failure (CLIF-C OF)/CLIF-Sequential Organ Failure Assessment

(CLIF-SOFA) scores:

1. Respiratory failure;

2. Coagulation failure;

3. Severe cardiovascular failure requiring the use of vasopressors;

3. ACLF grade 3: Presence of three or more organ failures as per EASL CLIF criteria as described in the EASL-Clinical Practice Guideline on decompensated liver cirrhosis;

4. Presence of spontaneous or secondary bacterial peritonitis;

5. Presence of spontaneous bacterial pleural empyema;

6. Patients with medical history of spontaneous bacterial peritonitis over the past 4 weeks;

7. Known active tuberculosis, or latent tuberculosis requiring treatment;

8. Presence of uncontrolled severe infection at SCR or Baseline (BL);

9. Patients with seizure disorder;

10. Patients with history of upper gastro-intestinal bleeding over the past 2 weeks, acute bleeding or bleeding upon paracentesis at SCR or BL;

11. Contraindication for paracentesis;

12. Coagulation disorders such as disseminated intravascular coagulation, hemophilia, known congenital or acquired Von Willebrand disease or platelet function defects;

13. Transjugular intrahepatic portosystemic shunt procedure or any major abdominal surgery having occurred in the past 4 weeks prior to SCR;

14. Potential or known hypersensitivity to liposomes;

15. Potential or known risk factors for allergic/anaphylactoid like reactions (e.g., mastocytosis/elevated basal tryptase) or multiple hypersensitivities;

16. Patients with known Porto-pulmonary hypertension and hepato-pulmonary syndrome;

17. Patients after organ transplantation receiving immunosuppressive medication;

This includes but is not limited to hepatocellular carcinoma outside Milan criteria, cholangiocarcinoma, extrahepatic cancer over the past 2 years, people who inject drugs or individuals formerly injecting drugs on substitution therapy;

19. Need for Renal Replacement Therapy or any extracorporeal liver support device (e.g., MARS®, Prometheus®, Plasmapheresis);

20. Alfapump® in place to manage ascites;

21. ACLF due to severe alcoholic steatohepatitis in patients with ongoing excessive alcohol intake with a Maddrey Score = 32 requiring steroid treatment;

22. ACLF due to acute viral hepatitis A, B, B+D, C or E requiring antiviral treatment;

23. ACLF due to autoimmune hepatitis requiring high-dose steroid treatment;

24. Pregnancy and lactation;

25. Women of child-bearing potential who are not willing to use adequate contraception;
