Head-to-head evidence
Etravirine vs Ulonivirine
Same mechanism, same race: design-graded trial evidence for both assets, with the grading rationale shown. Grades describe the quality of the evidence, never the merits of either security.

Etravirine · Intelence
Marketed by Johnson & Johnson
NCT00254046 · Phase 3 · completed
Participants were randomized and blinded to etravirine or placebo on top of background therapy. A significantly larger share of patients on etravirine achieved viral suppression than on placebo.
Ulonivirine
Developed by Merck & Co.
NCT04564547 · Phase 2 · completed
Randomized, triple-masked phase 2b switch study of once-weekly islatravir plus ulonivirine in virologically suppressed HIV-1 infection (161 participants). All three primary endpoints are adverse-event rates reported descriptively; no efficacy comparison was posted as primary.
Next expected readout: August 2027 · NCT06891066 (registry estimate)
