Brief Summary:
The purpose of this study is to compare the anti-HIV efficacy, safety and effect of serum lipids of two boosted protease inhibitor-based HAART regimens (ARV/RTV v. LPV/RTV) in HIV-1 infected subjects who have experienced their first virologic failure while receiving a NNRTI-containing HAART regimen.
