Head-to-head evidence
Alogliptin 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.

NCT00286429 · Phase 3 · completed
The 390-participant trial was randomized, quadruple-blind, and placebo-controlled, with 130, 131, and 129 participants assigned to placebo, alogliptin 12.5 mg, and alogliptin 25 mg, respectively. Both primary HbA1c comparisons were statistically significant in favor of alogliptin, but HbA1c is a surrogate measure, so the evidence does not establish a strong clinical-outcome grade.
Next expected readout: December 2026 · NCT07093476 (registry estimate)
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.
Next expected readout: October 2026 · NCT07711171 (registry estimate)
