NCT05063071

Brief Summary

TAF treatment for HBV prophylaxis could lead to significant reduction in ALT and significant improvement in renal function. However, data are scarce regarding to TAF monotherapy without HBIG for HBV prophylaxis in post orthotopic liver transplant with HBV-related disease. This study is based on a real-world, multi-center, prospective study to assess the effectiveness and safety of TAF for HBV prophylaxis, which will fill in gaps with TAF monotherapy without HBIG in post liver transplant.

Study Arms (1)

TAF monotherapy without HBIG

EXPERIMENTAL

The standard dose of TAF 25mg daily was used. TAF can be used on the first day after orthotopic liver transplantation. No HBIG was used before, during, or after transplantation; and therapeutic vaccination was not routinely used.

Drug: Tenofovir Alafenamide 25 MG

Interventions

After orthotopic liver transplant, all patients will receive Tenofovir Alafenamide monotherapy without HBIG for HBV Prophylaxis.
