Brief Summary

This is a 2-part, phase 3 clinical study evaluating the antiretroviral activity and safety/tolerability of islatravir (ISL), doravirine (DOR), and a fixed dose combination (FDC) of DOR/ISL (also known as MK-8591A) in heavily treatment-experienced (HTE) participants with human immunodeficiency virus type 1 (HIV-1) infection. It is hypothesized that the percentage of participants receiving DOR/ISL to achieve ≥0.5 log10 decrease in HIV-1 ribonucleic acid (RNA) from study baseline (Day 1) to Day 8 is superior to placebo, each given in combination with failing antiretroviral therapy (ART).

Detailed Description

Part 1 of this study (Day 1 to Day 7) is the double-blind period in which participants receive either ISL, DOR, DOR/ISL, or placebo. Part 2 of this study (Day 8 to Week 97) is the open-label period in which all participants receive DOR/ISL + optimized background therapy (OBT).
