Head-to-head evidence
CL-197 vs Dapivirine
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.

CL-197
Developed by Henan Genuine Biotech
NCT05944848 · Phase 1 · completed
The study randomly assigned healthy volunteers to active drug or matching placebo and blinded participants, care providers, investigators, and outcome assessors, which are the hallmarks of a well-controlled study. However, it tested only safety and drug levels in healthy volunteers rather than any HIV outcome, and results have not been posted.

Dapivirine · Dapivirine Vaginal Ring
Marketed by International Partnership for Microbicides
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.
