Brief summary

This study was designed to test the safety and effectiveness of EPZICOM(abacavir/lamivudine) and TRUVADA (emtricitabine/tenofovir) for the treatment of HIV infection when both are used in combination with KALETRA (lopinavir/ritonavir) over 96 weeks

Interventions

The intervention is an active comparator regimen containing tenofovir/emtricitabine + abacavir/lamivudine placebo + lopinavir/ritonavir.

The experimental intervention is a regimen containing abacavir/lamivudine + tenofovir/emtricitabine placebo + lopinavir/ritonavir.

Inclusion criteria

* Males as females at least 18 years old. (A female is eligible to enter and participate in this study if she is of: non child-bearing potential, child bearing potential with a negative pregnancy test and agrees to approved contraception methods, or agreement for complete abstinence.) * Subject is antiretroviral-naïve (defined as having ≤14 days of prior therapy with any NRTI and no prior therapy with either a PI or NNRTI). * Subject has plasma HIV-1 RNA ≥ 1,000 copies/mL at screening. * Subject is willing and able to understand and provide written informed consent prior to participation in this study.

Exclusion criteria

Percentage of Participants With HIV-1 RNA <50 Copies/mL at Week 48 by Missing=Failure (M=F), Switched Included Analysis.

A blood sample was drawn to determine the amount of HIV-1 RNA virus in copies/mL at Week 48. The percentage of participants with HIV-1 RNA \<50 copies/mL were tabulated by treatment arm with stratification by baseline HIV-1 RNA (\<100,000 copies/mL and \>=100,000 copies/mL).

Time frame: Week 48

Population: The Intent-To-Treat-Exposed (ITT-E) population which included all randomized participants that had received at least one dose of study medication. In the missing=failure, switched included analysis, participants who had switched their randomized treatment for other treatment were considered as failures, i.e., HIV-1 RNA \>=50 copies/mL.

Secondary

Percentage of Participants With HIV-1 RNA <50 Copies/mL at Weeks 48 and 96 in Participants With Baseline HIV-1 RNA >=100,000 Copies/mL

A blood sample was drawn to determine the amount of HIV-1 RNA virus in copies/mL at Week 48 and 96. The percentage of participants with HIV-1 RNA \<50 copies/mL at Weeks 48 and 96 were tabulated by treatment arm in participants with baseline HIV-1 RNA \>=100,000 copies/mL.

Time frame: Weeks 48 and 96

Population: The Intent-To-Treat-Exposed (ITT-E) population. The secondary analysis methods were M=F, switch included, TLOVR, Observed, and M/D=F
