Brief Summary:
A 48-week study to investigate the safety and effectiveness of a new compact formulation of two already FDA-approved anti-HIV drugs in subjects who have already been receiving treatment for their HIV infection.

Condition or disease Intervention/treatment Phase
Infection, Human Immunodeficiency Virus I HIV Infection Drug: abacavir/lamivudine Drug: abacavir Drug: lamivudine Drug: tenofovir Phase 3

Detailed Description:
A phase III, randomized, open-label, parallel, multicenter study to evaluate treatment with fixed-dose combination of abacavir/lamivudine (600mg/300mg) once-daily versus abacavir (300mg) twice-daily and lamivudine (300mg) once-daily in combination with tenofovir once-daily and a new PI or NNRTI for 48 weeks in ART-experienced HIV-1 infected patients.
