Summary

Tenofovir Disoproxil Fumarate is a nucleos(t)ide analogue that inhibits Hepatitis B Virus (HBV) growth, and is marketed in Japan with an indication for inhibition of HBV growth in subjects with chronic hepatitis B associated with HBV growth and abnormal liver function. This study has been planned to evaluate the virological effects and safety of switching from ETV to TDF in chronic hepatitis B (hepatitis B e-antigen \[HBeAg\])-positive and HBV- deoxyribonucleic acid (DNA) undetectable subjects. This study is designed as a multi-center, one-arm, post-marketing clinical study to investigate the HBsAg reduction in subjects who have not achieved the long-term goal, the loss of hepatitis B surface antigen (HBsAg). The study will be conducted in HBeAg-positive and HBV-DNA undetectable subjects treated with ETV. After switching ETV to TDF, TDF will be administered for 96 weeks. Approximately 80 subjects will be screened to achieve 65 evaluable subjects.
