Description of intervention(s) / exposure
Treatment: Drugs - DOR/ISL
Treatment: Drugs - ART

Experimental: Doravirine/Islatravir (DOR/ISL) - Participants who were previously treated with continuous background antiretroviral therapy (ART) will receive DOR/ISL, a fixed dose combination (FDC) of 100 mg doravirine (DOR)/0.75 mg islatravir (ISL) orally once daily for 96 weeks.

Active comparator: Baseline Background Antiretroviral Therapy (ART) - Participants will receive continuous background ART for 48 weeks and DOR/ISL, a FDC of 100 mg DOR/0.75 mg ISL orally once daily for 48 weeks.


Treatment: Drugs: DOR/ISL
A FDC of 100 mg DOR/ 0.75 mg ISL taken in tablet form, orally, once daily

Treatment: Drugs: ART
Baseline background ART regimen will be administered as per approved label. ART medication will not be provided by the Sponsor; participants will provide their own ART medications. Allowed drug classes include nucleoside analog reverse transcriptase inhibitors (NRTIs), non-nucleoside reverse transcriptase inhibitors (NNRTIs), protease inhibitors (PIs), integrase strand transferase inhibitors (InSTIs), fusion inhibitors, chemokine receptor 5 (CCR5) antagonists, post-attachment inhibitor, and pharmacokinetic (PK) boosters.

Summary
Brief 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.
