This is a phase 3, randomized, controlled, double-blind, multisite clinical study of a once-daily fixed dose combination (FDC) of 100 mg doravirine/0.75 mg islatravir (DOR/ISL \[also known as MK-8591A\]) in treatment-naïve participants living with human immunodeficiency virus type-1 (HIV-1) infection. The primary objectives are to evaluate the antiretroviral activity, safety, and tolerability of DOR/ISL compared to bictegravir/emtricitabine/tenofovir alafenamide (BIC/FTC/TAF). The primary hypothesis is that DOR/ISL is noninferior or superior to BIC/FTC/TAF treatment based on the percentage of participants with HIV-1 ribonucleic acid (RNA) \<50 copies/mL at Week 48.
Double-blind treatment with the assigned intervention occurs from Day 1 to Week 96, followed by an open-label portion up to Week 144. Participants who benefit from treatment in the opinion of the Investigator may continue their assigned intervention up to Week 168 (or until they have the option to enroll in a DOR/ISL 100 mg/0.25 mg study, whichever is sooner).
100 mg DOR/0.75 mg ISL FDC single tablet taken once daily by mouth.
BIC/FTC/TAF 50/200/25 mg FDC single tablet taken once daily by mouth.
Placebo single tablet matched to BIC/FTC/TAF taken by mouth.
Placebo single tablet matched to DOR/ISL taken by mouth.
