This trial will evaluate the safety and efficacy of HepaStem compared to placebo in patients with a cirrhotic liver condition called Acute on Chronic Liver Failure (ACLF). The study will be performed in multiple centers and in a double-blinded manner, meaning neither the patients nor the treating physicians know who is on placebo or the study drug.
- Conditions
- Cirrhotic patients who are hospitalized for Acute on chronic liver failure (ACLF), ACLF combines an acute deterioration of liver function in an individual with pre-existing chronic liver disease and extrahepatic organ failures characterized by high short-term mortality (30-40% at 28days). The development of ACLF is associated with exacerbated systemic inflammation that may indeed cause organ failures.MedDRA version: 24.0Level: PTClassification code 10077305Term: Acute on chronic liver failureSystem Organ Class: 10019805 - Hepatobiliary disordersTherapeutic area: Diseases [C] - Digestive System Diseases [C06]

Patients must fulfill all of the following criteria in order to be eligible for trial enrollment:
1. Are adults aged between 18 and 70 years old.
2. Have an initial diagnosis of ACLF at the investigational site.
3. Have ACLF grade 1 or 2 according to the EASL-CLIF Consortium definition.
4. Have a total bilirubin = 5 mg/dL.
5. Are able to read, understand and give written informed consent.
If the patient is unable to fully understand the study and based on the investigator’s judgment, the ICF must be signed by a legal or authorized representative of the patient according to local regulation. In case of hepatic encephalopathy (HE), the ICF must be signed by the patient after encephalopathy improvement, if possible.
Are the trial subjects under 18? no
Number of subjects for this age range:
F.1.2 Adults (18-64 years) yes
F.1.2.1 Number of subjects for this age range 70
F.1.3 Elderly (>=65 years) yes
F.1.3.1 Number of subjects for this age range 30
Patients presenting with any of the following criteria will not be included in the study:
1. Have a MELD-Na score > 35.
2. Have underlying cirrhosis due to biliary disease.
3. Have underlying cirrhosis due to autoimmune hepatitis.
4. Have active bleeding at a non-compressible site or at a compressible site that, in the opinion of the investigator, poses an unacceptable risk for the patient’s participation in the study.
5. Have received treatment for bleeding complications during the current hospitalization and has a persistent high risk for re-bleeding that, in the opinion of the investigator, poses an unacceptable risk for the patient’s participation in the study.
6. Have a complete portal vein thrombosis.
7. Have coagulation disturbances defined as:
o fibrinogen < 80 mg/dL
o platelets < 50 x 10³/mm³
8. Are requiring chronic dialysis therapy.
9. Have had a cerebrovascular, myocardial, limb arterial thrombotic event, or history for both thrombotic and hemorrhagic cerebrovascular events within 12 months prior to the Screening and not considered stabilized by the investigator.
10. Have a previous history of myocardial infarction and/or cardiac failure, with an ejection fraction rate (EFR) = 40%.
11. Have an inability to maintain mean blood pressure (BP) > 60 mmHg despite use of vasopressors.
12. Have severe pulmonary arterial hypertension defined as mean pulmonary arterial pressure (MPAP) = 45 mmHg (or right ventricular systolic pressure = 50 mmHg) by echocardiography.
13. Have hepatopulmonary syndrome.
14. Are receiving mechanical ventilation due to respiratory failure.
15. Have known or suspected hypersensitivity or allergy to any of the components of the HepaStem diluent, dimethyl sulfoxide (DMSO), or bovine serum albumin.
16. Have a history of severe allergies to drugs and/or a history of severe anaphylactic reactions.
17. Have undergone a major invasive procedure within 2 weeks of randomization. These are open surgeries (the proper healing of the scar should be verified by the investigator).
o Liver biopsy (transjugular or percutaneous), paracentesis, and transjugular intrahepatic portosystemic shunt (TIPS) are not considered as major invasive procedures.
18. Had a previous organ transplantation and/or treatment with cell-based therapy.
19. Are accepted as High Urgency status patient by the organ allocation system.
20. Have active primary or recurrent malignant disease (including hepatocellular carcinoma) or have been in remission from clinically significant malignancy for < 5 years.
o Patients with cervical carcinoma in situ that has been resected with no evidence of recurrence or metastatic disease for at least 3 years may participate in the study.
o Patients with basal cell or squamous epithelial skin cancers that have been completely resected with no evidence of recurrence for at least 3 years may participate in the study.
21. Are receiving immunosuppressive drugs, except glucocorticoids.
o Patients receiving glucocorticoids administered for treatment of severe alcoholic hepatitis may participate in the study.
22. Have a contraindication to or are unwilling to take glucocorticoids to prevent infusion-like reaction.
23. Have persistently positive blood cultures despite 48 hours of antibiotic therapy that indicates uncontrolled bacterial infection.
24. Have diagnosis of invasive aspergillosis.
25. Have known infection with human immunodeficiency virus (HIV).
26. Have a history of hepatitis D virus infection.
27. Are women of child
