Head-to-head evidence
DBPR108 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.

DBPR108
Developed by CSPC Pharmaceutical Group
NCT04161430 · Phase 3 · completed
In this randomized, quadruple-blind, placebo- and active-controlled Phase 3 trial, 766 patients with type 2 diabetes were randomized to DBPR108, sitagliptin, or placebo. DBPR108 reduced HbA1c significantly more than placebo at 24 weeks, with a treatment difference whose confidence interval excluded no effect.
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.
