Abstract

The present invention relates to the identification of a profile of antibodies in an individual with chronic hepatitis B (CHB) wherein the existence of this profile is indicative that the individual will achieve or has achieved a functional cure (FC). The present invention further identifies an epitope profile or profile on Hepatitis B virus surface antigen (HBsAg) which represents targets for antibodies which enable a level of clearance to be achieved to reach a functional cure for CHB. Level of occupancy of the epitope profile is indicative that a functional cure will or will not be achieved.

Abstract

The present invention relates generally to viral variants exhibiting reduced sensitivity to agents such as nucleoside or nucleotide analogs or other DNA polymerase antagonists and/or reduced interactivity with immunological reagents. More particularly, the present invention is directed to hepatitis B virus (HBV) variants exhibiting complete or partial resistance to nucleoside or nucleotide analogs or other DNA polymerase antagonists and/or reduced interactivity with antibodies to viral surface components including reduced sensitivity to these antibodies. The present invention further contemplates assays for detecting such viral variants, which assays are useful in monitoring anti-viral therapeutic regimens and in developing new or modified vaccines directed against viral agents and in particular HBV variants. The present invention also contemplates the use of the viral variants to screen for and/or develop or design agents capable of inhibiting infection, replication and/or release of the virus.
