Long‐term hepatitis B surface antigen (HBsAg) kinetics during entecavir treatment in Korean patients—Functional cure unlikely

The aim of this study was to investigate the on‐treatment kinetics of quantitative HBsAg during entecavir therapy to predict the treatment period needed to achieve functional cure. From a cohort of 1009 CHB treatment‐naïve patients who were started on entecavir, the kinetics of quantitative HBsAg decline was assessed in 410 patients by a linear mixed model. The difference in the kinetics of quantitative HBsAg was determined based on the HBeAg...
