Brief Summary

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

The purpose of this protocol is to obtain pharmacodynamic and pharmacokinetic data on ABI-H0731 and to provide the opportunity for preliminary evaluation of combination therapy of ABI-H0731 with currently approved antiviral treatment for chronic hepatitis B.

Detailed Description

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

The Phase 1b/2a assessments of the dose-related safety, PK, and initial antiviral efficacy of ABI-H0731 in hepatitis B patients will be conducted at approximately 17 different sites to meet enrollment goals of 108 chronic hepatitis B patients.
