A Phase 3, Randomized, Active-Controlled, Double-Blind 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 Bictegravir/Emtricitabine/Tenofovir Alafenamide (BIC/FTC/TAF)

In Brief

A Phase 3 clinical trial evaluating DOR/ISL, BIC/FTC/TAF, and 2 other interventions for HIV-1 Infection. Active but no longer recruiting, targeting 514 participants across 49 sites in 6 countries.

Detailed Summary

The primary objectives of this study are to evaluate the antiretroviral activity of a switch to Doravirine/Islatravir (DOR/ISL) compared with continued Bictegravir/Emtricitabine/Tenofovir Alafenamide (BIC/FTC/TAF) at Week 48; and to evaluate the safety and tolerability of a switch to DOR/ISL compared with continued BIC/FTC/TAF, through Week 48. The primary hypotheses are that (1) DOR/ISL is non-inferior to continued BIC/FTC/TAF, 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; and (2) DOR/ISL is superior to BIC/FTC/TAF, as assessed by the percentage of participants with HIV-1 RNA ≥50 copies/mL at Week 48.
