Head-to-head evidence
Azvudine 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.

NCT04303598 · Phase 3 · status unknown
This is a randomized, double-blind, active-controlled trial testing whether azvudine achieves viral suppression as well as an established comparator, using a recognized clinical measure of HIV control, but results are not yet posted so the outcome is unknown. (Independently confirmed by a second model, in-session-confirm:claude-opus-20260822.)
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)
