Head-to-head evidence
Sitagliptin vs SYR-472
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.

SYR-472
Developed by Takeda Pharmaceutical Company
NCT02324569 · Phase 3 · completed
The 12-week comparison randomized 240 participants and used quadruple blinding with placebo control. The primary HbA1c endpoint was met, with a statistically significant treatment difference, but HbA1c is a surrogate laboratory measure rather than a hard clinical endpoint; the subsequent long-term period was open-label.
