A Switch to Doravirine/Islatravir (DOR/ISL) in Participants With Human Immunodeficiency Virus Type 1 (HIV-1) Who Are Virologically Suppressed on Antiretroviral Therapy (ART) (MK-8591A-051)
A Switch to Doravirine/Islatravir (DOR/ISL) in Participants With Human Immunodeficiency Virus Type 1 (HIV-1) Who Are Virologically Suppressed on Antiretroviral Therapy (ART) (MK-8591A-051)

NCT05631093

Active Not RecruitingPhase 3

Sponsor: Merck Sharp & Dohme LLC

Conditions: HIV-1 Infection

Interventions: ART, DOR/ISL

Countries: United States, Australia, Canada, Colombia, Japan, South Africa, Switzerland, United Kingdom

The primary objectives of this study are to evaluate the safety and tolerability of a switch to Doravirine/Islatravir (DOR/ISL) compared with continued baseline antiretroviral therapy (ART), through Week 48; and to evaluate the antiretroviral activity of a switch to DOR/ISL compared with continued baseline ART at Week 48. The primary hypothesis is that DOR/ISL is non-inferior to continued baseline ART, as assessed by the percentage of participants with HIV-1 ribonucleic acid (RNA) ≥50 copies/mL at Week 48, with a margin of 4 percentage points used to define non-inferiority.

Eligibility criteria
Inclusion Criteria:

* Is Human Immunodeficiency Virus-1 (HIV-1) positive with plasma HIV-1 Ribonucleic Acid (RNA) \<50 copies/mL at screening
* Has been receiving continuous, stable oral 2-drug or 3-drug combination (± PK booster) antiretroviral therapy ART with documented viral suppression (HIV-1 RNA \<50 copies/mL) for ≥3 consecutive months prior to providing documented informed consent and has no history of prior virologic treatment failure on any past or current regimen
* Female is not a participant of childbearing potential (POCBP); or if a POCBP uses an acceptable contraceptive method or abstains from penile-vaginal intercourse as their preferred and usual lifestyle; has a negative highly sensitive pregnancy test; and whose medical history, menstrual history, and recent sexual activity has been reviewed by the investigator

Exclusion Criteria:

* Has active hepatitis B virus (HBV) infection
* Has chronic hepatitis C virus (HCV) infection consistent with cirrhosis
* Has a ≤5 years prior history of malignancy
* Is taking or is anticipated to require systemic immunosuppressive therapy, immune modulators, or strong and moderate cytochrome P450 3A (CYP3A) inducers
* Has taken long-acting HIV therapy at any time
* Is currently participating in or has participated in a clinical study and received (or is receiving) an investigational compound or device from 45 days prior to Day 1 through the study treatment period
* Has a documented or known virologic resistance to Doravine (DOR)
