  Purpose

This study will compare the response of subjects who failed a first-line ATV-containing regimen and who have the 150L-containing virus to subsequent protease inhibitor (PI)-containing therapy with that of a cohort who has failed a first-line reverse transcriptase inhibitor (NNRTI), and is subsequently receiving PI-containing therapy.

Study Population

HIV infected individuals on first line ATV based HAART with presence of I50L mutation & HIV infected PI naïve on failed NNRTI based regimen.

Criteria

Inclusion Criteria:

  • Currently on a first-line antiretroviral regimen containing ATV with a confirmed rebound and a genotype that verifies the presence of an 150L mutation OR on a first-line regimen containing an NNRTI and PI-naive, with a confirmed rebound

Exclusion Criteria:

  • Women of child bearing potential who are unwilling or unable to use an acceptable method to avoid pregnancy for the entire study period and for up to 8 weeks after the study.
  • Women who are pregnant or breastfeeding.
  • A life expectancy of <12 months.
  • Presence of a newly diagnosed HIV-related opportunistic infection or any other medical condition requiring acute therapy at the time of enrollment.
  • Active alcohol or substance abuse sufficient, in the investigator's opinion, to prevent adequate adherence to study therapy or to increase the risk of developing pancreatitis or chemical hepatitis.
