Study summary

This is a multicenter, randomized, open-label control trial of two arms conducted at 10 centres in China.The aim was to investigate whether sequential combination therapy with Thymosin alpha 1 and entecavir is superior to continuous ETV monotherapy in HBeAg-positive chronic hepatitis B patients with previous long-term entecavir therapy (≥ 2 years), and to select the optimal patients who may benefit from sequential combination therapy.
