Study to Evaluate Switching From Regimens Consisting of a Nonnucleoside Reverse Transcriptase Inhibitor Plus Emtricitabine and Tenofovir DF to the Elvitegravir/Cobicistat/Emtricitabine/Tenofovir DF Single-Tablet Regimen in Virologically Suppressed, HIV-1 Infected Patients
A Phase 3b Randomized, Open Label Study to Evaluate Switching From Regimens Consisting of a Non-nucleoside Reverse Transcriptase Inhibitor (NNRTI) Plus Emtricitabine (FTC) and Tenofovir DF (TDF) to the Elvitegravir/Cobicistat/ Emtricitabine/Tenofovir Disoproxil Fumarate Single-Tablet Regimen (EVG/COBI/FTC/TDF) in Virologically Suppressed, HIV 1 Infected Patients
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.

Phase 3
Allocation: Randomized
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Parallel Assignment
Masking: Open Label
Primary Purpose: Treatment
  • Acquired Immunodeficiency Syndrome
  • HIV Infections
  • Drug: NNRTI
    NNRTI agents administered according to prescribing information; allowed NNRTIs include efavirenz (EFV), nevirapine, or rilpivirine.
  • Drug: FTC/TDF
    FTC/TDF (200/300 mg) administered according to prescribing information
    Other Name: Truvada
  • Drug: Stribild
    Stribild® (elvitegravir/cobicistat/emtricitabine/tenofovir disoproxil fumarate; E/C/F/TDF) (150/150/200/300 mg) STR administered orally once daily with food
  • 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.
    Intervention: Drug: Stribild
  • 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.
    Interventions:
    • Drug: NNRTI
    • Drug: FTC/TDF

  • Be stable on the current formulation(s) of an antiretroviral regimen consisting of an NNRTI plus FTC/TDF for ≥ 6 consecutive months preceding the screening visit. This includes those who began a regimen with individual drug components and subsequently simplified to include a fixed-dose combination formulation of the same drugs.
  • Be on the first or second antiretroviral regimen with documented undetectable plasma HIV 1 RNA levels for ≥ 6 months preceding the screening visit
  • No previous use of any approved or experimental integrase strand transfer inhibitor (INSTI) for any length of time
  • Documented historical genotype prior to starting initial antiretroviral therapy showing no known resistance to TDF or FTC
  • HIV RNA < 50 copies/mL at screening

  • Females of childbearing potential must agree to utilize protocol recommended contraception methods or be nonheterosexually active, practice sexual abstinence from screening throughout the duration of the study period and for 12 weeks for participants on EFV/FTC/TDF or efavirenz or 30 days for the rest of participants following the last dose of study drug
  • Female participants who utilize hormonal contraceptive as one of their birth control methods must have used the same method for at least three months prior to study dosing
