The multi-center, open-label Phase 2 trial is designed to evaluate the safety, tolerability and efficacy of the combination of VIR-2218 and VIR-3434 in approximately 90 adult patients (ages 18 to 65) with chronic HBV infection receiving nucleot(s)ide reverse transcriptase inhibitor therapy. Both VIR-2218 and VIR-3434 will be administered via subcutaneous injection at varying dose levels over the course of the trial for a treatment period ranging from four to 20 weeks, and a follow-up period of up to 116 weeks, depending on the dosing cohort.

…VIR-2218 is an investigational small interfering ribonucleic acid (siRNA) designed to inhibit the production of all HBV proteins (X, polymerase, S and core), which may be acting as immune tolerogens. VIR-3434 is an investigational HBV-neutralizing monoclonal antibody designed to block entry of all 10 genotypes of HBV into hepatocytes, as well as reduce the level of virions and subviral particles in the blood. It has also been Fc engineered to include the XX2 “vaccinal mutation,” allowing it to potentially function as a therapeutic T cell vaccine against HBV.
