A Prospective, Randomized, Open Label Phase IV Study to Evaluate the Rationale of Switching From Fixed Dose Abacavir (ABC)/Lamivudine (3TC) to Fixed Dose Tenofovir DF (TDF)/Emtricitabine (FTC) in Virologically Suppressed, HIV-1 Infected Patients Maintained on a Ritonavir Boosted Protease Inhibitor Containing Antiretroviral Regimen

This protocol describes a prospective, randomized, open-label, multicenter study to evaluate the safety and efficacy of switching from fixed dose abacavir (ABC)/lamivudine (3TC) to fixed dose emtricitabine (FTC)/tenofovir disoproxil fumarate (TDF) in virologically suppressed, human immunodeficiency virus type 1 (HIV-1) infected subjects maintained on a ritonavir-boosted protease inhibitor (PI/r)-containing antiretroviral (ARV) regimen. Duration of treatment is 48 weeks.

Primary Outcomes

Description: The percentage of participants with HIV-1 RNA < 200 copies/mL based on TLOVR algorithm at Week 48 was summarized. Participants were considered nonresponders in the TLOVR analysis if they experienced virologic rebound prior to or at Week 48, discontinued study before Week 48, or added a new antiretroviral (ARV) agent prior to completion of the study. Virologic rebound was defined as 2 consecutive HIV-1 RNA values >= 200 copies/mL or the last HIV-1 RNA value >= 200 copies/mL followed by discontinuation from the study.

Measure: Percentage of Participants With HIV-1 Ribonucleic Acid (RNA) < 200 Copies/mL Through Week 48 Based on Time to Loss of Virologic Response (TLOVR) Algorithm

Time: Baseline to 48 weeks

Secondary Outcomes

Description: The percentage of participants with PVR for HIV-1 RNA cutoff at 200 copies/mL at Week 48 was summarized. Pure virologic response was the percentage of subjects who did not have a virologic rebound. Virologic rebound was defined as two consecutive HIV-1 RNA values >= 200 copies/mL or the last HIV-1 RNA value >= 200 copies/mL followed by discontinuation from the study.
