Head-to-head evidence
Dapivirine vs Elsulfavirine
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.

NCT02489461 · Phase 2/3 · completed
The study randomized 150 participants and used double blinding with an active efavirenz comparator. Its primary endpoint was the proportion with HIV-1 RNA below 400 copies/mL at Week 12, but no results are posted, so the outcome comparison cannot be assessed.
