Study of Once-Weekly Islatravir and Ulonivirine Compared to Daily BictegravirEmtricitabineTenofovir Alafenamide in Adults with HIV-1 Who Have Not Received Treatment Before

What this Trial Is About

Researchers are evaluating new treatment options for people living with HIV-1 Human Immunodeficiency Virus Type 1 who have not been treated before. The current standard treatment, antiretroviral therapy ART, involves taking multiple medicines daily and may cause other health problems. This study aims to compare a new study ART combining two medicines, islatravir and ulonivirine, taken once a week, against the standard daily ART to see if it works as well and is safe and tolerable. Participants will receive one of several treatments for 96 weeks the study ART with islatravir and ulonivirine taken once weekly, the standard ART with bictegraviremtricitabinetenofovir alafenamide BICFTCTAF taken once daily, or combinations involving placebos matching these treatments. The study includes two phases Phase 2 which is open-label, and Phase 3 which is double-blind and randomized. During the study, participants will have regular assessments including measuring the amount of HIV-1 RNA in their blood and monitoring for adverse events and medication tolerance. Researchers will evaluate how well the treatments control the virus and affect immune cells over 24, 48, and 96 weeks. Safety monitoring will continue for about 102 weeks. The total study duration for participants is up to 96 weeks of treatment plus follow-up.
