A Phase 3, Randomized, Active-Controlled, Open-Label Clinical Study to Evaluate a Switch to Doravirine/Islatravir (DOR/ISL 100 mg/0.25 mg) Once-Daily in Participants With HIV-1 Who Are Virologically Suppressed on Antiretroviral Therapy

Merck Sharp & Dohme LLC·interventional·Posted Nov 30, 2022·Updated Nov 21, 2025

In Brief

A Phase 3 clinical trial evaluating ART and DOR/ISL for HIV-1 Infection. Active but no longer recruiting, targeting 553 participants across 53 sites in 8 countries.

Detailed Summary

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.
