Clinical Trial Summary

Most anti-HIV regimens include a non-nucleoside reverse transcriptase inhibitor (NNRTI); however, some individuals fail on these regimens. The purpose of this study is to evaluate the safety and effectiveness of the protease inhibitor (PI) lopinavir/ritonavir (LPV/r) in HIV infected individuals who are failing an anti-HIV regimen that includes an NNRTI.


Clinical Trial Description

Standard effective antiretroviral therapy for HIV infected individuals includes three-drug combinations of two nucleoside reverse transcriptase inhibitors (NRTIs) with either a PI or an NNRTI. However, three-drug regimens may not be ideal in resource-limited settings, where viral load and resistance testing may not be readily available. The purpose of this study is to evaluate the safety and efficacy of the PI LPV/r alone in treatment-experienced, PI-naive HIV infected individuals who are experiencing virologic failure on three-drug regimens.

This study will last 104 weeks. All participants will receive LPV/r twice daily for up to 104 weeks. Participants who experience virologic failure will receive emtricitabine/tenofovir disoproxil fumarate once daily in addition to LPV/r twice daily for the remainder of the study.

There will be 16 study visits for participants on LPV/r monotherapy and 12 study visits for participants who have intensified LPV/r with emtricitabine/tenofovir disoproxil fumarate. Blood collection and clinical assessment will occur at all visits; urine collection and resistance testing will occur at selected visits. ;
