A Phase 3 Randomized, Active-Controlled, Double-Blind Clinical Study to Evaluate the Antiretroviral Activity, Safety, and Tolerability of Doravirine/Islatravir Once-Daily in HIV-1 Infected Treatment-Naïve Participants
In Brief
A Phase 3 clinical trial evaluating DOR/ISL, BIC/FTC/TAF, and 2 other interventions for HIV-1 Infection. Completed, enrolled 599 participants across 95 sites in 13 countries.

Detailed Summary
This is a phase 3, randomized, controlled, double-blind, multisite clinical study of a once-daily fixed dose combination (FDC) of 100 mg doravirine/0.75 mg islatravir (DOR/ISL \[also known as MK-8591A\]) in treatment-naïve participants living with human immunodeficiency virus type-1 (HIV-1) infection. The primary objectives are to evaluate the antiretroviral activity, safety, and tolerability of DOR/ISL compared to bictegravir/emtricitabine/tenofovir alafenamide (BIC/FTC/TAF). The primary hypothesis is that DOR/ISL is noninferior or superior to BIC/FTC/TAF treatment based on the percentage of participants with HIV-1 ribonucleic acid (RNA) \<50 copies/mL at Week 48.

Timeline
Arms & Interventions
Treatment-naïve participants living with human immunodeficiency virus-1 (HIV-1) that had not received ≤10 days of prior antiretroviral therapy received blinded fixed dose combination (FDC) Doravirine/Islatravir (DOR/ISL) (100 mg doravirine \[DOR\]/0.75 mg islatravir \[ISL\]) and placebo to Bictegravir/Tenofovir Alafenamide/Emtricitabine (BIC/FTC/TAF) once daily (QD) from Day 1 to Week 96, and open-label DOR/ISL up to Week 144. At Week 144, participants who consent to enter the optional open-label study extension continued to receive open-label QD FDC of DOR/ISL (100 mg/0.75 mg) for an additional 24 weeks, up to Week 168.
Treatment-naïve participants living with HIV-1 that had not received ≤10 days of prior antiretroviral therapy received blinded BIC/FTC/TAF (50 mg bictegravir \[BIC\], 200 mg emtricitabine \[FTC\], 25 mg tenofovir alafenamide \[TAF\]) and placebo to FDC DOR/ISL QD from Day 1 to Week 96, and open-label BIC/FTC/TAF up to Week 144. At Week 144, participants who consent to enter the optional open-label study extension continued to receive QD BIC/FTC/TAF (50 mg/200 mg/25 mg) for an additional 24 weeks, up to Week 168.
