Overview

**ABI-H0731 + tenofovir disoproxil fumarate** is a combination therapy under development for the treatment of chronic hepatitis B virus (HBV) infection. **ABI-H0731** is a first-generation small molecule inhibitor of the HBV core protein that interferes with viral replication by blocking core protein assembly, preventing pregenomic RNA (pgRNA) encapsidation, and inhibiting covalently closed circular DNA (cccDNA) formation, thereby preventing new HBV formation and the maintenance of the virus in infected cells[1][3][5]. **Tenofovir disoproxil fumarate** is a nucleotide analog reverse transcriptase inhibitor (NtRTI) that inhibits HBV reverse transcriptase and prevents viral DNA chain elongation, acting as a primary backbone therapy for HBV and HIV-1 infections[2][4]. The combination is investigated for additive or synergistic reductions in HBV viral load, aiming for greater antiviral activity than either agent alone.
