The objective of this 96-week study was to evaluate the safety and antiviral efficacy of emtricitabine/tenofovir disoproxil fumarate (FTC/TDF, coformulated; Truvada®) with or without hepatitis B immunoglobulin (HBIg) in preventing the recurrence of chronic hepatitis B following liver transplantation, in participants who were chronically infected with hepatitis B prior to transplantation.
