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.
EU CTIS ID: 2022-500252-28-00
What this study is testing
The primary objective is to demonstrate the efficacy of 2 infusions (i.v.) of HepaStem at 1.0 million cells per kg (7-day interval) on the overall survival proportion 90 days post-first infusion.

Who can take part
You may be able to join if
- 1. Are adults aged between 18 and 75 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 more or equal 5 mg per dL.
- 5. Are able to read, understand and give written informed consent. Only in case of hepatic encephalopathy (HE) due to ACLF, 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. After encephalopathy improvement, if possible, the ICF must be signed by the patient.
You likely can't join if
- 1. Have a MELD-Na score more than 35.
- 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.
- 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.
