Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to test 2 different dosing regimens of GW433908/ritonavir (RTV) versus lopinavir (LPV)/RTV when each is given with 2 active reverse transcriptase inhibitors (RTIs), in patients who have taken anti-HIV drugs without success.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Patients will receive 2 dosing regimens of GW433908/RTV or LPV/RTV, in combination with 2 active RTIs, after failing their first or second protease inhibitor-containing regimen. Patients are required to be on therapy at time of screening and must remain on this therapy until Day 1.
