A Novel Extracorporeal Liver Support Therapy In ALCF and to Evaluate the Efficacy of DIALIVE 2.0, a Liver Dialysis Device.

Exclusion Criteria

• •A-TANGO ACLF grade ≥2 for more than 10 days prior to inclusion

• •Bacterial infection or sepsis unresponsive to treatment with antimicrobials for 48 hours indicated by (a) persistent pyrexia (b) rising white cell count, creactive protein and lactate (c) persistently positive cultures for bacteria or fungi and/or (d) worsening clinical state indicated by escalating requirement for fluid resuscitation, increasing vasopressors requirements or increasing organ support.
• •Invasive fungal infection (clinical or radiological evidence, not solely biomarker positivity such as BDG or galactomannan)
• •Acute or sub-acute liver failure in the absence of cirrhosis
• •Post-hepatectomy liver failure or primary non-function following transplantation

• •INR \>3.0, unless sustained correction for \>24 hours following FFP/PCC treatment
• •Severe disseminated intravascular coagulopathy (DIC)
• •Persistent haemodynamic instability as defined by:
• •(i) Norepinephrine(NE) dose \>0.5µg/kg/min, or, (ii) If a second pressor is used, a composite Norepinephrine equivalence index (NEEI) of dose \>0.5µg/kg/min (iii) Arterial lactate level \>4mmol/L despite 24 hours of adequate fluid resuscitation and pressor therapy
• •Severe respiratory failure: PaO2/FiO2 (P/F) ≤ 200 mmHg or 27kPa

• •HCC outside of Milan criteria.
• •Acute, extensive, portal vein thrombosis extending to and occluding superior mesenteric vein
• •Major systemic illness, aside from liver disease, that in the opinion of the investigator would preclude the participant from participating in the study (e.g. coronary artery disease, cerebrovascular disease, chronic pulmonary disease, chronic kidney disease, serious psychiatric disease)
• •Pre-existing chronic kidney disease (CKD) defined as eGFR (estimated glomerular filtration rate) \<30 mL/min for 3 months or longer prior to screening

• •Any participant who has received an investigational drug or device within 30 days, or who is scheduled to receive another investigational drug or device during the course of the study (concomitant observational studies are allowed)
• •Uncontrolled seizures
• •Evidence of new intracranial pathology such as cerebral hemorrhage or infarction.
• •Participants diagnosed with Creutzfeldt-Jakob disease.
