Brief Summary:
The purpose of this study is to compare the use of HepeX-B versus HBIg, two anti-viral drugs, in patients who have received liver transplants due to liver failure caused by Hepatitis B infection. Patients will be evaluated over a 6 month to 1.5 year period to evaluate whether or not the drugs prevent the Hepatitis B virus from infecting the new liver.

Criteria

Inclusion Criteria:

  • Male and female patients who are 18 years of age or older,
  • Patients who are at least 6 months post first orthotopic liver transplantation (living or cadaveric donor) for treatment of end-stage liver disease due to HBV infection,
  • Patients who have received HBIg since transplantation and are on a stable regimen (i.e., same dose and frequency) for at least the 3 months immediately preceding study entry (Day 1),
  • Patients who have received treatment with an inhibitor of HBV polymerase for at least the 3 months immediately preceding study entry (Day 1),
  • Patients with undetectable HBsAg and HBV DNA concentrations on two consecutive tests at least 1 week apart during the screening period,
  • Female patients who are of childbearing potential, and males whose partners are women of childbearing potential, are required to use adequate contraception, and
