Head-to-head evidence
exendin-4 Fc fusion (JY09) vs semaglutide
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.

NCT06247748 · Phase 1 · completed
Every participant received the same open-label treatment with no control group, and the study measured drug-interaction and pharmacokinetic markers rather than a clinical benefit. No results have been posted.

NCT01720446 · Phase 3 · completed
This was a large randomized, double-blind, placebo-controlled trial with 1,648 participants receiving semaglutide and 1,649 receiving placebo. The hard clinical primary endpoint, first major adverse cardiovascular event, occurred in 6.6% versus 8.9% of participants; the prespecified non-inferiority comparison was met (hazard ratio 0.74, 95% CI 0.58–0.95, p<0.0001), and a post hoc superiority analysis was statistically significant (p=0.0167).
