Inclusion Criteria:

  • Adults of either gender and ages 18 to 70 years old
  • Subjects must have a diagnosis of end-stage liver disease (ESLD) due to alcohol, chronic hepatitis B virus (HBV) and hepatitis C virus (HCV) infections, autoimmune hepatitis, primary sclerosis cholangitis, primary biliary cirrhosis (cholangitis), cirrhosis as the result of Wilson disease, hemochromatosis, sarcoidosis and alpha 1 antitrypsin deficiency, cryptogenic cirrhosis and nonalcoholic steatohepatitis cirrhosis with a MELD-Na score >10 to <25 at screening.

  • Subject must have serum BUN <80 mg/dL.
  • Subject must have a eGFR <45 mL/min/1.73m2.
  • Subject may have had current and/or previous cardiopulmonary diseases precluding standard liver transplantation (e.g., coronary artery disease, portopulmonary hypertension, moderate chronic obstructive pulmonary disease).
  • Subject must agrees to avoid alcohol consumption during the study.

Exclusion Criteria:

  • Subject has primary hepatic neoplasms (hepatocellular carcinoma and cholangiocarcinoma).
  • Subject has active and/or uncontrolled severe infections requiring hospitalization and prolonged antimicrobial therapy.
  • Subject has renal failure with BUN >= 80 mg/dL.

  • Subject has previously treated neoplastic disease with less than a 2-year cancer free period.
  • Subject is pregnant or lactating.
  • Subject has known hypersensitivity to human serum albumin.
  • Subjects with uncontrolled hypertension (defined as a diastolic blood pressure of 110 mm Hg or higher).
  • Subject has recurrent/intractable ascites refractory to diuretics and requiring periodic large volume paracentesis.
  • Subject has primary alcoholic liver disease and has not demonstrated abstinence for at least 6 months while attending mandatory rehab programs (e.g., AA) and psychotherapy.

Arms of the Study

Arm 1

Arm Type

Experimental

Arm Label

LYG-LIV0001

Arm Description

Open label group of subjects with end stage liver disease receiving increasing doses of the experimental therapy.

Outcomes

Primary Outcome Measures

Dosage Selection
The primary objective of the dose escalation is to confirm the optimal dose of transplanted hepatocytes to safely achieve adequate allogeneic hepatocyte (AH) engraftment
Safety of Engraftment of Hepatocytes in to Lymph Nodes
The primary safety objective of the dose escalation is to determine whether AH engraftments into the periduodenal lymph nodes in subjects with end-stage liver disease is safe as determined by the number/severity of adverse events
Efficacy of Engraftment of Hepatocytes in to Lymph Nodes
The primary efficacy objective of the dose escalation is to determine whether AH engraftments into the periduodenal lymph nodes in subjects with end-stage liver disease is efficacious in addressing some of the signs and symptoms of end-stage liver disease

Secondary Outcome Measures

Effectiveness of Selected Treatment to Modify the Liver Function Panel
Evaluate the effectiveness of hepatocyte transplants in modifying the liver function panel (total serum bilirubin, ammonia, prothrombin time, international normalized ratio, sodium, blood urea nitrogen, and creatinine) as measured through changes in laboratory biomarkers caused by end-stage liver disease
