Brief Summary
- The purpose of this study is to to prove that the long-term efficacy of strategy of treatment adjustment at W24 according to virological response based on ROADMAP concept is better than standard of care strategy.
- To evaluate the off-treatment durability of HBeAg seroconversion in patients who discontinued treatment due to sustained HBeAg seroconversion and HBV DNA\<300copies/ml with over 12 months consolidation treatment

ACTIVE COMPARATORInterventions
Patients will receive oral telbivudine 600mg, daily for 104 weeks, if HBV DNA breakthrough, add on oral adefovir 10mg daily Stopping rules: The participants who achieve HBeAg seroconversion and HBV DNA\<300copies/ml with over 12 months consolidation treatment in EFFORT study will discontinue treatment. The participants who don't meet the rules above will continue their previous treatment and follow up at the interval of 12 weeks until they finish the 156 weeks therapy or achieve the stopping rules. Follow up: The participants who stopped treatment will follow up at the interval of 12 weeks for 52 weeks. Of these patients, if they have confirmed virologic relapse during follow-up period, they will be excluded from the trial.
