Safety and Efficacy of a Switch to Doravirine, Tenofovir, Lamivudine (MK-1439A) in Human Immunodeficiency Virus (HIV-1)-Infected Participants Virologically Suppressed on an Anti-retroviral Regimen in Combination With Two Nucleoside Reverse Transcriptase Inhibitors (MK-1439A-024)

Inclusion Criteria

• •Have plasma Human Immunodeficiency Virus-1 Ribonucleic Acid (HIV-1 RNA) levels below the limit of quantification (BLoQ) (\<40 copies/mL by the Abbott RealTime HIV-1 Assay as determined by the central laboratory) at the screening visit.
• •Receiving antiretroviral therapy with a ritonavir- or cobicistat-boosted protease inhibitor (atazanavir, darunavir, or lopinavir) or cobicistat-boosted elvitegravir or a NNRTI (specifically, efavirenz, nevirapine, or rilpivirine) in combination with 2 Nucleoside Reverse Transcriptase Inhibitor (NRTIs) (and no other antiretroviral therapy) continuously for \>= 6 months.
• •Receiving first or second retroviral regimen (participants receiving a NNRTI at Screening must be on their first retroviral regimen)
• •No history of using an experimental NNRTI
• •Has a genotype prior to starting his/her initial antiretroviral regimen and no known resistance to any of the study agents
• •Not receiving lipid lowering therapy or on a stable dose of lipid lowering therapy at the time of enrollment
• •Has the following laboratory values at screening within 30 days prior to the treatment phase of this study: Alkaline phosphatase ≤ 3.0 x upper limit of normal (ULN), Serum aspartate aminotransferase (AST) and serum alanine aminotransferase (ALT) ≤ 5.0 x ULN, and Hemoglobin ≥9.0 g/dL (if female) or ≥10.0 g/dL (if male)
• •Has a calculated creatinine clearance at the time of screening ≥ 50 mL/min, based on the Cockcroft-Gault equation
• •Male or female participant not of reproductive potential or, if of reproductive potential, agrees to avoid becoming pregnant or impregnating a partner while receiving study drug and for 14 days after the last dose of study drug by complying with one of the following: 1) practice abstinence from heterosexual activity, or 2) use acceptable contraception during heterosexual activity
• •For inclusion in Study Extension 1 (optional): completed the Week 48 visit; considered to have derived benefit from study participation up to Week 48; considered to be a clinically appropriate candidate for an additional 2 years treatment with study drug
• •For inclusion in Study Extension 2 (optional): completed the Week 144 visit; considered to have derived benefit from study participation up to Week 144; considered to be a clinically appropriate candidate for an additional 2 years treatment with study drug
• •For inclusion in Study Extension 3 (optional): completed the Week 240 visit; considered to have derived benefit from study participation up to Week 240; considered to be a clinically appropriate candidate for an additional 2 years treatment with study drug
