History of Changes
The purpose of this study is to compare the antiretroviral activity of MK-1439A, a single-tablet, once-daily (q.d.) fixed-dose combination (FDC) containing 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 HIV. The primary hypothesis is that MK-1439A 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.

Drug : MK-1439A
Drug : ATRIPLA™
Intervention Model: Parallel Assignment
Masking: Double (Participant, Investigator)
Primary Purpose: Treatment
|Official Title:||A Phase III Multicenter, Double-Blind, Randomized, Active Comparator-Controlled Clinical Trial to Evaluate the Safety and Efficacy of MK-1439A Once-Daily Versus ATRIPLA™ Once-Daily in Treatment-Naïve HIV-1 Infected Subjects|

Primary Outcome Measures
- Proportion of participants with HIV-1 RNA <50 copies/mL at Week 48 [ Time Frame: Week 48 ]
- Proportion of participants with neuropsychiatric adverse events (AEs) [ Time Frame: Up to Week 48 ]
- Proportion of participants with HIV-1 RNA <50 copies/mL at Week 96 [ Time Frame: Week 96 ]
- Change in cluster of differentiation 4 (CD4) cell counts at Week 48 [ Time Frame: Baseline and Week 48 ]
- Change in CD4 cell counts at Week 96 [ Time Frame: Baseline and Week 96 ]
- Proportion of participants with HIV-1 RNA <40 copies/mL at Week 48 [ Time Frame: Week 48 ]

|Study Start Date:||June 5, 2015|

|Estimated Primary Completion Date:||March 20, 2017 (Final data collection date for primary outcome measure)|
Treatment-naive HIV-infected participants will receive MK-1439A, a single-tablet FDC containing MK-1439 100 mg + lamivudine 300 mg + tenofovir disoproxil fumarate 300 mg, q.d. by mouth for 96 weeks. Participants will also take 1 placebo tablet matched to ATRIPLA™ q.d. by mouth for 96 weeks in order to maintain blinding.
One MK-1439A tablet taken by mouth
Treatment-naive HIV-infected participants will receive ATRIPLA™, a single-tablet FDC containing efavirenz 600 mg + emtricitabine 200 mg + tenofovir disoproxil fumarate 300 mg (equivalent to 245 mg tenofovir disoproxil), q.d. by mouth for 96 weeks. Participants will also take 1 placebo tablet matched to MK-1439A q.d. by mouth for 96 weeks in order to maintain blinding.
One ATRIPLA™ tablet taken by mouth
