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.
||Endpoint Classification: Safety Study
Intervention Model: Parallel Assignment
Primary Purpose: Treatment
||A Phase III, Randomized, Multicenter, Parallel Group, Open-Label, Three Arm Study to Compare the Efficacy and Safety of Two Dosing Regimens of GW433908/Ritonavir (700mg/100mg Twice Daily or 1400mg/200mg Once Daily) Versus Lopinavir/Ritonavir (400mg/100mg Twice Daily) for 48 Weeks in Protease Inhibitor Experienced HIV-Infected Adults Experiencing Virological Failure
| Estimated Enrollment:
| Study Start Date:
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.
|Ages Eligible for Study:
||13 Years and older
|Genders Eligible for Study:

- Have taken PI drugs for at least 12 straight weeks and have had virologic failure on the PIs.
- Are now taking antiretroviral therapy.
- Are male or female and are at least 13 years old (or 18 if local requirement) and can provide consent from parent or guardian if under 18.
- Are females unable to have children or, if are able to have children, are not pregnant and agree to use approved birth control.
Patients will not be eligible for this study if they:
- Have taken APV or LPV for more than 1 week.
- Have taken tenofovir disoproxil fumarate (TDF) or adefovir.
- Have taken more than 2 PIs.
- Are unable to take 2 active RTIs, as specified by the study.
- Have an active CDC Category C disease.
- Have certain abnormal laboratory tests.
- Are pregnant or breast-feeding.

- Have taken drugs that affect the immune system (corticosteroids, interleukins, interferons) or drugs with anti-HIV activity (hydroxyurea or foscarnet) within 28 days prior to taking the study drug.
- Have had any HIV vaccine within 3 months before taking the study drug.
- Have taken certain other drugs within 28 days prior to taking the study drug, or expect to need them during the study.
