Summary

This trial is testing a new once-daily pill for HIV-1 infection. The pill contains two drugs, doravirine and islatravir. The trial will compare the new pill to a currently available pill that contains three drugs, bictegravir, emtricitabine, and tenofovir alafenamide. The trial will last 48 weeks and the primary outcome will be the percentage of participants with HIV-1 RNA <50 copies/mL at Week 48.

Who is the study for?
This trial is for adults who have recently been diagnosed with HIV-1 and haven't started treatment yet. They should not be pregnant or breastfeeding, must use reliable contraception if they can bear children, and cannot have a history of certain cancers or other conditions that might affect the study results.
What is being tested?
The study tests a once-daily pill combining two drugs (Doravirine/Islatravir) against an established HIV treatment (Bictegravir/Emtricitabine/Tenofovir). Participants are randomly assigned to one of these treatments in a blinded manner to compare effectiveness and safety at reducing the virus levels after 48 weeks.
What are the potential side effects?
Potential side effects may include but are not limited to nausea, headache, fatigue, diarrhea, skin reactions, and changes in liver enzymes. The exact side effects will be monitored throughout the trial as each individual's reaction can vary.

Trial Design

2Treatment groups
Experimental Treatment
Active Control
Group I: Group 1: DOR/ISLExperimental Treatment2 Interventions
Treatment-naïve participants with HIV-1 receive blinded DOR/ISL and placebo to BIC/FTC/TAF once daily (QD) from Day 1 to Week 96, and open-label DOR/ISL up to Week 144. Participants who are benefitting from treatment are then eligible to continue on open-label DOR/ISL up to Week 168.
Group II: Group 2: BIC/FTC/TAFActive Control2 Interventions
Treatment-naïve participants with HIV-1 receive blinded BIC/FTC/TAF and placebo to DOR/ISL QD from Day 1 to Week 96, and open-label BIC/FTC/TAF up to Week 144. Participants who are benefitting from treatment are then eligible to continue on open-label BIC/FTC/TAF up to Week 168.
