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 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.

Primary	Percentage of Participants Who Discontinued Study Intervention Due to an AE up to Week 48	An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a study intervention. The percentage of participants who discontinued study intervention due to an AE up to week 48 is presented.	Up to 48 weeks

Baseline measurement of CD4+ T-cell count is defined as the day 1 value for each participant. Change from baseline in CD4+ T-cell count at week 96 using the data as observed (DAO) approach is presented.

The number of participants who demonstrate drug resistance is presented.	Week 48
Secondary	Participants With Evidence of Viral Drug Resistance-associated Substitutions at Week 96	Viral drug resistance is defined as participants with confirmed HIV-1 RNA =400 copies/mL and/or genotypic or phenotypic analysis of data showing evidence of resistance to the study drug administered. The number of participants who demonstrate drug resistance is presented.	Week 96
Secondary	Participants With Evidence of Viral Drug Resistance-associated Substitutions at Week 144	Viral drug resistance is defined as participants with confirmed HIV-1 RNA =400 copies/mL and/or genotypic or phenotypic analysis of data showing evidence of resistance to the study drug administered. The number of participants who demonstrate drug resistance is presented.	Week 144
Secondary	Change From Baseline in Body Weight at Week 48	Body weight was measured and recorded at baseline and week 48. Participants removed their shoes and wore a single layer of clothing at each measurement. The mean change from baseline in body weight at week 48 is presented.	Baseline and Week 48
Secondary	Change From Baseline in Body Weight at Week 96	Body weight was measured and recorded at baseline and week 96. Participants removed their shoes and wore a single layer of clothing at each measurement.	Baseline and Week 96
