Head-to-head evidence
MP-513 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.

MP-513
Developed by Mitsubishi Tanabe Pharma
NCT00974090 · Phase 3 · completed
This was a randomized, quadruple-blind, placebo-controlled Phase 3 study of 194 adults with type 2 diabetes inadequately controlled on sulfonylurea therapy, with a 12-week double-blind period followed by a 40-week open-label extension. The primary endpoint - change from baseline in HbA1c at Week 12 - is a hard, regulator-accepted measure of glycemic control, and the comparison clearly favored teneligliptin (LS mean -0.71% vs +0.29% for placebo, SE 0.06 per arm), however statistical significance is not reported.
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.
