Head-to-head evidence
Gemigliptin vs Sitagliptin
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.

NCT01787396 · Phase 3 · completed
This was a randomized, quadruple-blind trial (n=433) with three arms: gemigliptin plus metformin, gemigliptin alone (with a matching metformin placebo), and metformin alone (with a matching gemigliptin placebo). The primary endpoint, HbA1c change at 24 weeks, favored the combination over either monotherapy.
Sitagliptin · Januvia
Marketed by Merck & Co.
NCT00087516 · Phase 3 · completed
The trial randomized 741 participants to double-blind sitagliptin or placebo groups, providing a substantial controlled comparison. The primary endpoint, change in A1C at week 24, was statistically favorable for both sitagliptin doses (p<0.001), but A1C is a surrogate endpoint, so the evidence is rated moderate rather than strong.
