Head-to-head evidence
lixisenatide 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.

The 639 participants were randomly assigned to lixisenatide or active treatment with exenatide, but the study was not blinded. The primary HbA1c comparison met its prespecified non-inferiority criterion, with a between-group difference of 0.17 percentage points and a 95% confidence interval of 0.033 to 0.297, but HbA1c is a surrogate endpoint rather than a hard clinical outcome.

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).
Next expected readout: November 2026 · NCT07570810 (registry estimate)
