This is a clinical study for GC1102 to demonstrate preventing the recurrence of hepatitis B virus (HBV) infection following liver transplantation and a dose-finding study to determine its optional dose.
GC1102 is a new recombinant hepatitis B immunoglobulin (HBIG) from Chinese Hamster Ovary (CHO) cells. It is a monoclonal antibody and has high affinity and avidity to hepatitis B surface antigen and several advantages compared to HBIG derived from blood plasma of human donors. Volunteers will participate in the study, receive 24-week treatment with 80,000/100,000 IU of GC1102 or I.V HBIG and be followed up till 28 weeks.
