History of Changes
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.
Drug : Lopinavir/Ritonavir
Drug : Ritonavir
Drug : GW433908
Intervention Model: Parallel Assignment
Primary Purpose: Treatment
|Official Title:||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|
