Brief Summary:
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 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 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.

Primary Outcome Measures :
- Percentage of Participants With HIV-1 Ribonucleic Acid (RNA) <50 Copies/mL at Week 48 [ Time Frame: Week 48 ]The percentage of participants in each arm with HIV-1 RNA levels <50 copies/mL at Week 48 was determined. Plasma HIV-1 RNA levels were quantified with the Abbott RealTime HIV-1 Assay. Data were handled according to the US Food and Drug Administration (FDA) "snapshot" approach in which all missing data are considered treatment failures, regardless of the reason.
- Percentage of Participants With Tier-1 Neuropsychiatric Adverse Events (AEs) [ Time Frame: Up to Week 48 ]The percentage of participants in each arm experiencing ≥1 pre-specified Tier-1 neuropsychiatric AEs was determined. The list of Tier-1 neuropsychiatric AE categories included "dizziness", "sleep disorders and disturbances", and "altered sensorium" (including disturbance in attention).
Secondary Outcome Measures :
- Percentage of Participants With HIV-1 RNA <50 Copies/mL at Week 96 [ Time Frame: Week 96 ]The percentage of participants in each arm with HIV-1 RNA levels <50 copies/mL at Week 96 will be determined. Plasma HIV-1 RNA levels will be quantified with the Abbott RealTime HIV-1 Assay. The US Food and Drug Administration (FDA) "snapshot" approach (i.e., all missing data handled as treatment failures, regardless of the reason) will be used for efficacy analyses.
- Percentage of Participants With HIV-1 RNA <40 Copies/mL at Week 48 [ Time Frame: Week 48 ]The percentage of participants in each arm with HIV-1 RNA levels <40 copies/mL (including target detected and target not detected) at Week 48 was determined. Plasma HIV RNA levels were quantified with the Abbott RealTime HIV-1 Assay. Data were handled according to the US Food and Drug Administration (FDA) "snapshot" approach in which all missing data are considered treatment failures, regardless of the reason.
- Percentage of Participants With HIV-1 RNA <40 Copies/mL at Week 96 [ Time Frame: Week 96 ]The percentage of participants in each arm with HIV-1 RNA levels <40 copies/mL (including target detected and target not detected) at Week 96 will be determined. Plasma HIV-1 RNA levels will be quantified with the Abbott RealTime HIV-1 Assay. The US Food and Drug Administration (FDA) "snapshot" approach (i.e., all missing data handled as treatment failures, regardless of the reason) will be used for efficacy analyses.
- Change From Baseline in CD4 Cell Counts at Week 48 [ Time Frame: Baseline (Day 1) and Week 48 ]The mean change from baseline in CD4 cell counts at Week 48 was assessed using the Observed Failure (OF) approach. With the OF approach, baseline values were carried forward for participants who discontinued prior to Week 48 due to lack of efficacy. Cell counts at Baseline and Week 48 were measured and expressed as cells/mm^3, and percent change was then calculated as [(Baseline counts - Week 48 counts)*100]. CD4 cell counts were quantified by a central laboratory using a commercially available assay.
- Change From Baseline in CD4 Cell Counts at Week 96 [ Time Frame: Baseline (Day 1) and Week 96 ]The mean change from baseline in CD4 cell counts at Week 96 will be assessed using the Observed Failure (OF) approach. With the OF approach, baseline values will be carried forward for participants who discontinued prior to Week 96 due to lack of efficacy. Cell counts at Baseline and Week 96 will be measured and expressed as cells/mm^3, and percent change will then be calculated as [(Baseline counts - Week 96 counts)*100]. CD4 cell counts will be quantified by a central laboratory using a commercially available assay.
- Percentage of Participants Experiencing ≥1 AE [ Time Frame: Up to Week 48 ]An AE is defined as any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment.
- Percentage of Participants Discontinuing From Study Medication Due to an AE(s) [ Time Frame: Up to Week 48 ]An AE is defined as any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment.
- Percentage of Participants With Tier-2 Neuropsychiatric AEs [ Time Frame: Up to Week 48 ]The percentage of participants in each arm experiencing ≥1 pre-specified Tier-2 neuropsychiatric AEs was determined. The list of Tier-2 neuropsychiatric AE categories included "depression and suicide/self-injury" and "psychosis and psychotic disorders".
- Change From Baseline in Fasting LDL-C at Week 48 [ Time Frame: Baseline (Day 1) and Week 48 ]The mean percent change from baseline in fasting (fast duration of ≥8 hours) LDL-C levels at Week 48 was determined for each arm. The Last Observation Carry Forward (LOCF) approach was applied to missing data and data collected after a participant initiated lipid-modifying therapy.
- Change From Baseline in Fasting Non-HDL-C at Week 48 [ Time Frame: Baseline (Day 1) and Week 48 ]The mean percent change from baseline in fasting (fast duration of ≥8 hours) non-HDL-C levels at Week 48 was determined for each arm. The LOCF approach was applied to missing data and data collected after a participant initiated lipid-modifying therapy.
- Change From Baseline in Fasting Cholesterol at Week 48 [ Time Frame: Baseline (Day 1) and Week 48 ]The mean percent change from baseline in fasting (fast duration of ≥8 hours) cholesterol levels at Week 48 was determined for each arm. The LOCF approach was applied to missing data and data collected after a participant initiated lipid-modifying therapy.
- Change From Baseline in Fasting Triglycerides at Week 48 [ Time Frame: Baseline (Day 1) and Week 48 ]The mean percent change from baseline in fasting (fast duration of ≥8 hours) triglycerides levels at Week 48 was determined for each arm. The LOCF approach was applied to missing data and data collected after a participant initiated lipid-modifying therapy.
- Change From Baseline in Fasting HDL-C at Week 48 [ Time Frame: Baseline (Day 1) and Week 48 ]The mean percent change from baseline in fasting (fast duration of ≥8 hours) HDL-C levels at Week 48 was determined for each arm. The LOCF approach was applied to missing data and data collected after a participant initiated lipid-modifying therapy.
- Percentage of Participants With HIV-1 RNA Below the Limit of Quantification (BLoQ) at Week 48 [ Time Frame: Week 48 ]The percentage of participants in each arm with HIV-1 RNA levels BLoQ of 40 copies/mL and target not detected at Week 48 was determined. Plasma HIV RNA levels were quantified with the Abbott RealTime HIV-1 Assay. Data were handled as observed.
- Percentage of Participants With HIV-1 RNA BLoQ at Week 96 [ Time Frame: Week 48 ]The percentage of participants in each arm with HIV-1 RNA levels BLoQ of 40 copies/mL and target not detected at Week 96 will be determined. Plasma HIV RNA levels will be quantified with the Abbott RealTime HIV-1 Assay. Data will be handled as observed.
- Plasma Concentration of Doravirine at Week 48 [ Time Frame: 0 hours post-dose and 2 hours post-dose on Week 48 ]Plasma samples were collected for analysis of doravirine concentration at Week 48. A total of 2 samples were collected: 1 prior to dosing and 1 collected between 0.5 and 2 hours post-dose.
