Clinical Trial 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 protocol-specified background antiretroviral regimen. The primary hypothesis is that a switch to MK-8591A will be non-inferior to continued treatment with baseline antiretroviral therapy (ART) as assessed by the percentage of participants with HIV-1 ribonucleic acid (RNA) ≥50 copies/mL at Week 48.
