Head-to-head evidence
Linagliptin vs Trelagliptin
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.

NCT00602472 · Phase 3 · completed
This was a randomized, double-blind, placebo-controlled trial with 1,058 participants, and its primary endpoint was met: adjusted HbA1c change was −0.72% with linagliptin versus −0.10% with placebo (p<0.0001). The evidence is considered moderate because HbA1c is a surrogate measure rather than a hard clinical endpoint.
Trelagliptin · Zafatek
Developed by Takeda Pharmaceutical Company
NCT03940183 · Phase 3 · completed
The trial randomized 254 participants to trelagliptin or placebo and used quadruple blinding. Its primary endpoint was the surrogate measure of change in HbA1c at week 24, but results were not posted, so whether the comparison favored trelagliptin is unknown.
Next expected readout: December 2026 · NCT07073768 (registry estimate)
