Description of intervention(s) / exposure
Treatment: Drugs - NNRTI
Treatment: Drugs - FTC/TDF
Treatment: Drugs - Stribild
Experimental: Stribild - Participants will switch from their baseline treatment regimen to Stribild for up to 96 weeks, and may continue to receive Stribild in the extension phase.
Active comparator: NNRTI+FTC/TDF - Participants will stay on their baseline treatment regimen antiretroviral regimen consisting of an NNRTI plus FTC/TDF for up to 96 weeks, and may switch to Stribild in the extension phase.
Treatment: Drugs: NNRTI
NNRTI agents administered according to prescribing information; allowed NNRTIs include efavirenz (EFV), nevirapine, or rilpivirine.
Treatment: Drugs: FTC/TDF
FTC/TDF (200/300 mg) administered according to prescribing information
Treatment: Drugs: Stribild
Stribild® (elvitegravir/cobicistat/emtricitabine/tenofovir disoproxil fumarate; E/C/F/TDF) (150/150/200/300 mg) STR administered orally once daily with food

Summary
Brief summary
This study will evaluate the noninferiority of Stribild® (elvitegravir/cobicistat/emtricitabine/tenofovir disoproxil fumarate (E/C/F/TDF)) single-tablet regimen (STR) relative to regimens consisting of a nonnucleoside reverse transcriptase inhibitor (NNRTI) plus Truvada® (FTC/TDF) in maintaining HIV-1 RNA \< 50 copies/mL at Week 48 in virologically suppressed, HIV-1 infected adults. This study will also evaluate the safety, tolerability, and efficacy of the two regimens through 96 weeks of treatment.
