Summary:

      The purpose of this study is to compare the antiretroviral activity of doravirine, tenofovir,
      lamivudine (MK-1439A), a single-tablet, once-daily (q.d.) fixed-dose combination (FDC)
      containing doravirine (MK-1439) 100 mg + lamivudine 300 mg + tenofovir disoproxil fumarate
      300 mg, with ATRIPLA™, a single-tablet FDC containing efavirenz 600 mg + emtricitabine 200 mg
      + tenofovir disoproxil fumarate 300 mg, in treatment-naive participants infected with human
      immunodeficiency virus (HIV). The primary hypothesis is that doravirine, tenofovir,
      lamivudine q.d. is non-inferior to ATRIPLA™ q.d. as assessed by the proportion of
      participants with HIV-1 ribonucleic acid (RNA) <50 copies/mL (by the Abbott RealTime HIV-1
      Assay) at Week 48. This study has a total duration of 192 weeks, including a 96-week
      double-blind period and a 96-week open-label period. The present results are based on the
      first 48 weeks of this ongoing study.

             indicated based on physician assessment

          -  Has never received antiretroviral therapy (ART)

        Exclusion Criteria:

             abuse

          -  Has been treated for a viral infection other than HIV-1 (e.g., hepatitis B) with an
             agent that is active against HIV-1

             study

          -  Has a current (active) diagnosis of acute hepatitis due to any cause (note:
             participants with chronic hepatitis B and C may enter the study as long as they
             fulfill all entry criteria, have stable liver function tests, and have no significant
             impairment of hepatic synthetic function)

          -  Is a female who is pregnant, breastfeeding, or expecting to conceive

          -  Is a female and is expecting to donate eggs or is male and is expecting to donate
