Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to determine if ABI-H0731 given in combination with a standard of care (SOC) hepatitis B virus (HBV) nucleos(t)ide reverse transcriptase inhibitor (NUC) medication is safe and effective in participants with chronic hepatitis B virus infection (cHBV).

Detailed Description

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

ABI-H0731 + SOC NUC

Virologically suppressed participants will receive ABI-H0731 along with SOC NUC (ETV, TDF or TAF) 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.

Group Type EXPERIMENTAL

ABI-H0731

Intervention Type DRUG

Participants will receive ABI-H0731 300 mg tablets orally once daily (QD).

SOC NUC

Intervention Type DRUG

Participants will continue on their SOC NUC (ETV, TDF or TAF) tablet orally as per approved package insert.

Placebo + SOC NUC

Virologically suppressed participants will receive matching placebo tablets and continue their SOC NUC (ETV, TDF or TAF) 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.

Group Type ACTIVE_COMPARATOR

SOC NUC

Intervention Type DRUG

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Male or female between ages 18 and 70 years
* Virologically-suppressed (defined as HBV DNA ≤limit of quantitation (LOQ) for at least 6 months before screening on SOC NUC therapy
* HBeAg-positive or HBeAg-negative at screening
* In good general health except for cHBV

Exclusion Criteria

* Co-infection with HIV, hepatitis C virus (HCV), hepatitis E virus (HEV) or hepatitis D virus (HDV)
* History or evidence of hepatic decompensation (including gastrointestinal bleeding or esophageal varices) at any time prior to or at time of screening
* Clinically significant cardiac or pulmonary disease, chronic or recurrent renal or urinary tract disease, liver disease other than HBV, endocrine disorder, autoimmune disorder, diabetes mellitus requiring treatment with insulin or hypoglycemic agents, neuromuscular, musculoskeletal, or mucocutaneous conditions requiring frequent treatment, seizure disorders requiring treatment, or other medical conditions requiring frequent medical management or pharmacologic or surgical treatment that in the opinion of the Investigator or the Sponsor makes the participant unsuitable for the study
* Previous treatment with an investigational agent for HBV other than ABI-H0731 in the last 6 months before screening
* History of hepatocellular carcinoma (HCC)
* Females who are lactating or pregnant or wish to become pregnant are excluded from the study
* Exclusionary laboratory parameters at screening include:

* Platelet count \<100,000/mm3
* Albumin \<lower limit of normal (LLN)
* Direct bilirubin \>1.2×upper limit of normal (ULN)
* Alanine aminotransferase (ALT) \>5×ULN at screening
* International Normalized Ratio (INR) \>1.5×ULN
* Glomerular filtration rate (GFR) \<60 mL/min/1.73 m2 by Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation
