abstract |
The present invention relates to methods for determining the potential of hepatitis B virus, HBV, variants to exhibit reduced sensitivity to Adefovir dipivoxil, ADV, and/or Tenofovir, TFV. The present invention is also directed to isolated HBV variants exhibiting decreased sensitivity to ADV and/or TFV. The present invention further contemplates methods for detecting agents having inhibitory activity to such viral variants, as well as the uses of such viral variants in the rational design of anti-HBV agents and in the manufacture of medicaments for the treatment and/or prophylaxis of HBV infection. |
