Head-to-head evidence
Emtricitabine/tenofovir disoproxil fumarate 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.

Shared mechanism: HIV reverse transcriptase · full HIV pipeline
Emtricitabine/tenofovir disoproxil fumarate · Truvada
Marketed by Gilead Sciences
NCT00323544 · Phase 3 · completed
This was a randomized, open-label, active-controlled trial of 220 participants, comparing Truvada with Combivir. Its primary endpoint was a laboratory measure—change in hemoglobin—not a hard clinical or endoscopic outcome. Registry results were not posted at the time of grading; the key result shown was recovered from the cited external source.
Next expected readout: December 2026 · NCT07584122 (registry estimate)
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)
