Additionally, 48 weeks of VIR-2218 plus PEG-IFN-α provided greater reductions in hepatitis B surface antigen (HBsAg) (mean decrease of -2.9 log10 IU/mL) compared to VIR-2218 alone or with shorter regimens of the combination.

New findings also demonstrate that concurrent initiation of VIR-2218 and pegylated interferon alpha (PEG-IFN-α) therapy resulted in substantial HBsAg reductions compared to VIR-2218 alone or with PEG-IFN-α following a VIR-2218 lead-in.
