Summary:

      The primary objective of this study is to evaluate the non-inferiority of switching to
      emtricitabine/rilpivirine/tenofovir alafenamide (FTC/RPV/TAF) fixed dose combination (FDC) as
      compared to continuing the non-nucleoside reverse transcriptase inhibitor (NNRTI) regimen of
      efavirenz /FTC/tenofovir disoproxil fumarate (EFV/FTC/TDF) FDC in virologically-suppressed
      HIV-1 infected participants.
    

Eligibility criteria:

        Key Inclusion Criteria:

          -  The ability to understand and sign a written informed consent form, which must be
             obtained prior to initiation of study procedures

          -  Currently receiving EFV/FTC/TDF FDC for ≥ 6 consecutive months preceding the screening
             visit

          -  Documented plasma HIV-1 RNA levels < 50 copies/mL (or undetectable HIV-1 RNA level
             according to the local assay being used if the limit of detection is > 50 copies/mL)
             for ≥ 6 months preceding the screening visit. Unconfirmed virologic elevation of ≥ 50
             copies/mL after previously reaching viral suppression (transient detectable viremia,
             or "blip") and prior to screening is acceptable

          -  Have no documented resistance to any of the study agents at any time in the past

          -  HIV-1 RNA < 50 copies/mL at the screening visit

          -  Hepatic transaminases (AST and ALT) ≤ 5 × upper limit of normal (ULN)

          -  Total bilirubin ≤ 1.5 mg/dL, or normal direct bilirubin

          -  Adequate hematologic function (absolute neutrophil count ≥ 1,000/mm^3; platelets ≥
             50,000/mm^3; hemoglobin ≥ 8.5 g/dL)

          -  Serum amylase ≤ 5 × ULN (individuals with serum amylase > 5 × ULN will remain eligible
             if serum lipase is ≤ 5 × ULN)

          -  Normal ECG (or if abnormal, determined by the Investigator to be not clinically
             significant)

          -  Adequate renal function: Estimated glomerular filtration rate ≥ 50 mL/min according to
             the Cockcroft-Gault formula

        Key Exclusion Criteria:

          -  Hepatitis B surface antigen (HBsAg) positive

          -  Hepatitis C antibody positive with detectable hepatitis C virus (HCV) RNA (individuals
             who have HCV antibody but no detectable HCV RNA are eligible to enroll)

          -  Individuals experiencing or with a medical history of decompensated cirrhosis (e.g.,
             ascites, encephalopathy, etc.)

          -  Females who are breastfeeding

          -  Positive serum pregnancy test

          -  Current alcohol or substance use judged by the Investigator to potentially interfere
             with the individual's study compliance

          -  A history of malignancy within the past 5 years (prior to screening) or ongoing
             malignancy other than cutaneous Kaposi's sarcoma (KS), basal cell carcinoma, or
             resected, non-invasive cutaneous squamous carcinoma. Individuals with cutaneous KS are
             eligible, but must not have received any systemic therapy for KS within 30 days of
             Baseline/Day 1 and must not be anticipated to require systemic therapy during the
             study

          -  Active, serious infections (other than HIV-1 infection) requiring parenteral
             antibiotic or antifungal therapy within 30 days prior to Baseline/Day 1

          -  Any other clinical condition or prior therapy that, in the opinion of the
             Investigator, would make the individual unsuitable for the study or unable to comply
             with dosing requirements

          -  Participation in any other clinical trial (including observational trials) without
             prior approval from the sponsor is prohibited while participating in this trial

          -  Individuals receiving ongoing therapy with any of the disallowed medications listed in
             the protocol, including drugs not to be used with FTC, RPV and/or TAF; or individuals
             with any known allergies to the excipients of FTC/RPV/TAF

        Note: Other protocol defined inclusion/exclusion criteria may apply.
