Head-to-head evidence
Sitagliptin vs Teneligliptin
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.

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.

Teneligliptin · Tenelia
Developed by Mitsubishi Tanabe Pharma
NCT00974090 · Phase 3 · completed
The trial was properly randomized and double-blinded with a placebo control and a real hard clinical endpoint (HbA1c change), and enrollment (~96-98 per arm) was reasonable for a 12-week phase 3 add-on study. However, the posted results report only least-squares mean changes with standard errors and no explicit statistical significance test for the primary comparison, so while the numeric difference favors teneligliptin, whether it formally met its pre-specified endpoint cannot be confirmed from this record alone.
