Head-to-head evidence
Afrezza vs GZR33
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.

NCT00332488 · Phase 3 · completed
The trial randomized 528 participants across three treatment groups and used an active comparator, but it was open-label rather than blinded and its primary endpoint was the surrogate measure HbA1c. The primary comparison was not met: HbA1c decreased by 0.70% with inhaled insulin plus metformin versus 0.78% with metformin plus secretagogue (p=0.420).
