Overview

Selgantolimod + tenofovir alafenamide is an investigational oral combination therapy for chronic hepatitis B virus (HBV) infection. **Selgantolimod** is a small molecule agonist of **Toll-like receptor 8 (TLR8)**, acting as an immunomodulator to stimulate immune responses, including increased cytokine and chemokine production and redistribution of immune cell subsets. **Tenofovir alafenamide** is a nucleotide reverse transcriptase inhibitor (NRTI), a prodrug of tenofovir, that is phosphorylated intracellularly to its active form, tenofovir diphosphate, which inhibits HBV replication by incorporation into viral DNA and chain termination. The combination aims for additive or synergistic effects targeting both viral replication (by TAF) and host immune activation (by selgantolimod) for potentially achieving functional HBV cure. This combination has shown modest declines in HBsAg and good safety/tolerability in phase II trials.[1][3]
