Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to compare the safety and efficacy of a combination of a QD regimen consisting on ritonavir boosted darunavir (FDC) and lamivudine versus ritonavir boosted darunavir (FDC) plus co-formulated tenofovir and emtricitabine or co-formulated tenofovir/lamivudine in naïve HIV-1 infected patients. Subjects will be ARV-naïve HIV-1-infected patients eligible to start ARV therapy according to current guidelines.Subjects will be adults ≥ 18 years of age who meet all of the inclusion criteria and none of the exclusion criteria.
