Primary Outcome Measures:
  • To compare HBV DNA suppression to levels below the limit of detection (<400 copies/ml) by week 48 in each group

Secondary Outcome Measures:
  • -HBV resistance at 48 weeks; -undetectable HBV DNA at weeks 12 & 24; -HBeAg and HBsAg seroconversion at weeks 24 & 48; -ALT chnages and rate of hepatic cytolysis; -HIV-1 RNA supression and CD4/CD8 changes over 48 weeks;

Enrollment: 36

Detailed Description:

A randomised multi-centre trial of tenofovir vs lamivudine vs tenofovir/lamivudine in antiretroviral naïve subjects with HIV/HBV co-infection over 48 weeks (Clinical Trial A). Plus, a 12 week viral kinetic sub-study comparing a sub-group of the patients on Clinical Trial A with a group of therapy naïve HBV mono-infected subjects (Substudy A1)
