Brief Summary
This study will evaluate the efficacy and safety of peginterferon alfa-2a or ADV, in participants with lamivudine-resistant HBeAg-positive chronic hepatitis B. Participants will be randomized to receive either peginterferon alfa-2a for 48 weeks in combination with oral lamivudine for the first 12 weeks, or ADV for 72 weeks in combination with oral lamivudine for the first 12 weeks. The anticipated time on study treatment is 72 weeks, and the target sample size is 255 individuals.

Study Arms (2)
ADV + Lamivudine
ACTIVE COMPARATORParticipants will receive ADV and lamivudine tablets at a dose of 10 mg orally QD for first 12 weeks followed by ADV for 60 weeks.
Peginterferon alfa-2a + Lamivudine
EXPERIMENTALParticipants will receive peginterferon alfa-2a injection at a dose of 180 micrograms (mcg) once weekly (QW) and 100 milligrams (mg) lamivudine tablets orally once daily (QD) for first 12 weeks followed by peginterferon alfa-2a for 36 weeks.
Interventions
ADV will be administered orally at a dose of 10 mg QD for 72 weeks.
Lamivudine tablets will be administered orally at a dose of 10 mg QD for 12 weeks.
Peginterferon alfa-2a injection will be administered at a dose of 180 mcg QW for 48 weeks.
