Primary Outcome Measures:

proportion of patients with plasma HIV RNA < 50 copies/mL at Week 24; safety and tolerability at week 24; change from baseline in key lipids at Week 12. [ Time Frame: Weeks 12 & 24 ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:

Additional HIV RNA analysis and CD4 cell counts at Week 24 and at Week 48; safety and tolerability at week 48; change from baseline in key lipids at Week 24 and 48. [ Time Frame: Weeks 24 & 48 ] [ Designated as safety issue: Yes ]
