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

NCT01617096 · Phase 3 · completed
This Phase 3 trial randomized 2,629 women to a monthly dapivirine vaginal ring or a placebo ring, with both participants and investigators blinded. The primary endpoint was HIV-1 seroconversion, and the results show 71 seroconversions among 1,313 women in the dapivirine group versus 97 among 1,313 in the placebo group; however, no p-value or confidence interval is provided in the registry, so it is uncertain whether this difference was statistically significant. Because the design is robust but the primary comparison's significance is not established, the evidence is moderate rather than strong.
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.
