Study to Evaluate Switching to Elvitegravir/Cobicistat/Emtricitabine/Tenofovir Alafenamide (E/C/F/TAF) Fixed Dose Combination (FDC) in Virologically-Suppressed HIV-1 Infected Adults Harboring the Archived Isolated NRTI Resistance Mutation M184V/M184I

The primary objective of the study is to evaluate the efficacy of elvitegravir/cobicistat/emtricitabine/tenofovir alafenamide (E/C/F/TAF) fixed-dose combination (FDC) after switching from a stable regimen consisting of emtricitabine/tenofovir disoproxil fumarate (FTC/TDF) or abacavir/lamivudine (ABC/3TC) plus a third antiretroviral (ARV) agent in participants harboring the archived nucleoside/nucleotide reverse transcriptase inhibitor (NRTI) resistance mutation M184V and/or M184I in human immunodeficiency virus (HIV) -1 reverse transcriptase. This is a two part study. If the rate of virologic failure in Part 1 is deemed acceptable, once the internal data monitoring committee officially completes the interim review, the study will continue to Part 2.
