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) entecavir (ETV) is safe and effective in participants with chronic hepatitis B infection (cHBV)

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a Phase 2a, multi-center, double-blind, placebo-controlled study evaluating ABI-H0731+ ETV vs ETV alone for the treatment of viremic hepatitis B "e" antigen (HBeAg)-positive participants with cHBV.

ABI-H0731 + SOC ETV

Participants with cHBV who are currently not being treated will receive ABI-H0731 along with SOC 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.

Group Type EXPERIMENTAL

ABI-H0731

Intervention Type DRUG

Participants will receive 300mg QD of ABI-H0731 tablets orally.

SOC ETV

Intervention Type DRUG

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.

Group Type EXPERIMENTAL

SOC ETV

Intervention Type DRUG

Participants will receive SOC ETV (0.5 mg QD) orally as per approved package insert.

Placebo Oral Tablet

Intervention Type DRUG

Participants will receive matching QD placebo tablets orally.

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
* HBeAg-positive at screening
* In good general health except for cHBV
* HBV viral load ≥2×105 IU/mL
* Hepatitis B surface antigen (HBsAg) \>1000 IU/mL at screening

Exclusion Criteria

* Any prior treatment with lamivudine or telbivudine, previous treatment with an investigational agent for HBV other than ABI-H0731; or any other SOC treatment for \>4 weeks
* 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:

* Platelet count \<100,000/mm3
* Albumin \<lower limit of normal (LLN)
* Direct bilirubin \>1.2×upper limit of normal (ULN)
* Alanine aminotransferase (ALT) \>10×ULN at screening
* Serum alpha fetoprotein (AFP) ≥100 ng/mL. If AFP at Screening is \>ULN but \<100 ng/mL, participant is eligible if a hepatic imaging study prior to the initiation of study drug reveals no lesions suspicious of possible HCC
* 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
