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.

Insulin Efsitora Alfa
Developed by Eli Lilly
NCT05275400 · Phase 3 · completed
The study randomized 986 participants to efsitora or active-control insulin degludec, but treatment was open-label rather than blinded. The primary HbA1c noninferiority endpoint was met, with a treatment difference of -0.089 percentage points and a 95% confidence interval of -0.191 to 0.013 within the prespecified 0.4% margin; the primary endpoint was a surrogate measure.
SAR341402
Marketed by Sanofi
NCT03211858 · Phase 3 · completed
The trial randomized 597 participants to SAR341402 or active-control NovoLog/NovoRapid, but treatment assignment was not blinded. The primary HbA1c endpoint met the prespecified non-inferiority margins, while HbA1c is a surrogate measure, so the evidence is considered moderate rather than strong.
