ABI-H0731 + SOC ETV
Participants with chronic hepatitis B infection (cHBV) who are currently not being treated will receive ABI-H0731 along with standard of care (SOC) entecavir (ETV) tablets orally for 24 weeks. Eligible participants may enter a separate extension study after Week 24 to continue open-label ABI-H0731 for up to an additional year if necessary. ABI-H0731: Participants will receive 300mg QD of ABI-H0731 tablets orally. SOC ETV: Participants will receive SOC ETV (0.5 mg QD) orally as per approved package insert.
Placebo + SOC ETV
Participants with cHBV who are currently not being treated will receive matching placebo along with SOC ETV tablets orally for 24 weeks. Eligible participants may enter a separate extension study after Week 24 to start treatment on open-label ABI-H0731 for up to a year if necessary. SOC ETV: Participants will receive SOC ETV (0.5 mg QD) orally as per approved package insert. Placebo Oral Tablet: Participants will receive matching QD placebo tablets orally.
