Study Summary

This study will evaluate the safety and efficacy of a switch to MK-8591A (a fixed dose combination of doravirine and islatravir) in human immunodeficiency virus -1 (HIV-1)-infected participants virologically suppressed on a regimen of bictegravir/emtricitabine/tenofovir alafenamide (BIC/FTC/TAF). The primary hypothesis is that a switch to MK-8591A will be non-inferior to continued treatment with BIC/FTC/TAF as assessed by the proportion of participants with HIV-1 ribonucleic acid (RNA) ≥50 copies/mL at Week 48. Participants who benefit from their assigned intervention (as determined by investigator) will be able to continue treatment through a 24-week study extension.
