Assess Safety and Efficacy of ELAD (Extracorporeal Liver Assist System) in Subjects With Alcohol-Induced Liver Failure

Subjects randomized to the ELAD® group will receive treatment with ELAD® for a maximum of
five (5) 24 hour periods as well as standard of care treatment.

Subjects randomized to the Control group will receive standard of care treatment throughout
the study.

The ITT population includes all randomized subjects assigned to the group to which they were
randomized, irrespective of actual treatment administered. Participant, Baseline
Characteristics, and Outcome Measures used the ITT population. The safety population is
defined as all subjects who are randomized based on actual treatment received. All serious
adverse events and all non-serious adverse events analyses used the safety population.

Inclusion Criteria:

- Age ≥ 18 years;

- Total bilirubin ≥ 8 mg/dL;

- A clinical diagnosis of alcohol-induced liver decompensation (AILD), based upon
evidence (by lab test, medical history, or family interview) of a clinical judgment of
a temporal (6 weeks or less) and causal relationship between use of alcohol and this
onset of symptoms;

- Subjects meeting inclusion criteria 1 through 3 will be classified as having either:

a. Severe acute alcoholic hepatitis (AAH), with: i. Medical history of alcohol abuse;
AND ii. Maddrey score of ≥ 32; AND iii. AAH documented by either:

1. Confirmatory liver biopsy; OR 2. Two or more of the following:

1. Hepatomegaly,

2. AST > ALT,

3. Ascites,

4. Leukocytosis (WBC count above lab normal at site), OR

b. Alcohol-induced decompensation of chronic liver disease that is not acute alcoholic
hepatitis (as defined above), with: i. MELD score of 18-35; AND ii. Underlying chronic
liver disease documented by:

1. Liver biopsy, AND/OR

2. Laboratory findings, AND/OR

3. Medical history;

- Not eligible for liver transplant during this hospitalization;

- Subject or legally authorized representative must provide Informed Consent;

- Subject must be eligible for Standard of Care treatment as defined in the protocol.

Exclusion Criteria:

- Platelet count < 40,000/mm3;

- International Normalization Ratio (INR) > 3.5;

- MELD Score > 35;

- AST > 500 IU/L;

- Evidence of infection unresponsive to antibiotics;

- Evidence of reduction in total bilirubin of 20% or more in the previous 72 hours, if
available. Bilirubin measurements must be taken at least 12 hours after any procedure
known to artificially alter serum bilirubin (e.g., administration of packed red blood
cells, plasma exchange);

- Evidence of hemodynamic instability as defined by the following:

1. Systolic blood pressure < 90 mmHg with evidence of diminished perfusion
unresponsive to fluid resuscitation and/or low-dose pressor support; OR

2. Mean arterial pressure (MAP) < 60 mmHg with evidence of diminished perfusion
unresponsive to fluid resuscitation and/or low-dose pressor support; OR

3. Requirement for escalating doses of vasopressor support prior to Screening; OR

4. Subject at maximum vasopressor dose at Screening;

- Evidence of active bleeding or of major hemorrhage defined as requiring ≥ 2 units
packed red blood cells to maintain stable hemoglobin occurring within 48 hours of
Screening;

- Clinical evidence of liver size reduction due to cirrhosis (liver size of the
craniocaudal diameter (sagittal view) < 10 cm when measured on the mid clavicular line
(or equivalent measurement) by ultrasound, or liver volume < 750 cc as determined by
CT), unless Investigator interpretation of the clinical evidence indicates liver size
of < 10 cm or volume < 750 cc is not considered reduced for the individual subject;

- Occlusive portal vein thrombosis impairing hepatopetal flow, or evidence of bile duct
obstruction;

- Evidence by physical exam, history, or laboratory evaluation, of significant
concomitant disease with expected life expectancy of less than 3 months, including,
but not limited to:

1. Severe acute or chronic cardiovascular, central nervous system, or pulmonary
disease;

2. Cancer that has metastasized or has not yet been treated;

- Subject has chronic end-stage renal disease requiring chronic hemodialysis for more
than 8 weeks (not classified as hepatorenal syndrome);

- Subject has liver disease related to homozygous hemachromatosis, Wilson's Disease, has
non-alcoholic fatty liver disease, or Budd-Chiari Syndrome;

- Pregnancy as determined by β-human chorionic gonadotropin (HCG) results, or lactation;

- Participation in another investigational drug, biologic, or device study within one
month of enrollment, except for observational studies (the observational study setting
should not affect safety and/or efficacy of the VTI-208 clinical trial);

- Previous liver transplant;

- Previous enrollment in the treatment phase of another ELAD trial (e.g. a subject is
not disqualified from enrollment in VTI-208 if they were screened for VTI-210 but did
not qualify for enrollment in the treatment phase of the study and therefore did not
receive ELAD or Control treatment;

- Have a Do Not Resuscitate or a Do Not Intubate (DNR/DNI) directive (or such local
equivalent) or any other Advanced Directive limiting Standard of Care in place (the
DNR/DNI criterion is not applicable in the UK);

- Refusal to participate in the VTI-208E follow-up study;

- Inability to provide an address for home visits.
