New HIV pill combo aims to keep virus suppressed with just one daily tablet
NCT ID NCT05631093
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether switching to a once-daily pill containing doravirine and islatravir (DOR/ISL) works as well as staying on current HIV medications for people whose virus is already undetectable. About 550 adults with HIV-1 who have been on stable therapy for at least 3 months will be randomly assigned to either switch to DOR/ISL or continue their current regimen. The main goals are to see if the switch keeps the virus suppressed and is safe over 48 weeks.
