Bulevirtide (BLV), the first-in-class entry inhibitor, is a 47-amino acid synthetic liner lipopeptide derived from the preS1 domain of the HBV large surface that targets the NTCP, the entry receptor for HBV/HDV. By blocking this receptor, new infections are prevented, and infected hepatocytes are replaced by naive cells that will be protected from infection. Consequently, viral spread in the liver is prevented.
