An Exploratory Study of RGT Strategy on Optimal NUC-experienced Patients

Summary

The aim of current study is to investigate whether the HBsAg clearance rate can be improved if applying RGT((Response-Guided Therapy) strategy in HBeAg positive CHB(chronic hepatitis B) patients treated by nucleoside analogue(NUC) achieved HBVDNA\<1000copies/ml，and HBsAg\<5000IU/ml; \&HBeAg\<100PEIU/ml (or470s/co), combined with PEG-IFN a-2a for 24 weeks.
