Continuing Lamivudine Versus Switching to Entecavir in Patients Who Achieved Undetectable HBV DNA
Randomized, Open-Labeled Study Evaluating the Antiviral Efficacy, Safety, and Tolerability of Continuing Lamivudine Therapy or Switching to Entecavir in Subjects With Chronic Hepatitis B Who Achieved Undetectable HBV DNA

This is a randomized, open-labelled, prospective 96-week study comparing the antiviral efficacy and safety of switching to entecavir 0.5mg QD from lamivudine versus maintaining lamivudine 100mg QD treatment in CHB patients currently receiving lamivudine monotherapy.

Entecavir has a higher potent antiviral efficacy and a lower drug resistance rate than those of Lamivudine in nucleoside-naïve CHB patients. The switch from Lamivudine to Entecavir in patients who have undetectable hepatitis B virus DNA (HBV DNA < 60 IU/mL) may lead to more prolonged viral suppression to undetectable level by PCR method, compared to patients with continuous lamivudine treatment. The results of this study will provide a rationale for switch treatment from one antiviral to another one, especially from LAM to ETV.
