Detailed Description
This is a phase 3 prospective, single arm open label study to be conducted t approximately 4 study sited located in th e USA. Approximately 25 HBV DNA negative patients who underwent liver transplant at least one year prior, due to chronic hepatitis B infection will bwe eligible for study participation. The study consist of a total of 16 study visit and the duration of participation will be 20 weeks for each patients. Patients will be converted from the intravenous standard HBIG to Nabi-HB subcutaneous administration according to the individual scheduled dosing interval.
