Could a simpler HIV pill work just as well? new study compares 2-drug combo to standard 3-drug therapy.
NCT ID NCT06333808
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether switching to a new 2-drug combination pill (bictegravir/lenacapavir) is as safe and effective as staying on the standard 3-drug pill (Biktarvy) for people with HIV-1 whose virus is already suppressed. About 577 participants who have been on Biktarvy for at least 6 months will be randomly assigned to either the new 2-drug pill or continue Biktarvy. The main goal is to see if the new pill keeps the virus under control at 48 weeks.
