Comparison of Doravirine, Tenofovir, Lamivudine (MK-1439A) and ATRIPLA™ in Treatment-Naive Human Immunodeficiency Virus Type 1 (HIV-1)-Infected Participants (MK-1439A-021)

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-1439A) 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 384 weeks, including a 96-week double-blind period and an additional 288-week open-label period.
