Head-to-head evidence
Afrezza vs AT278
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.
Type 2 Diabetes
Shared mechanism: Insulin receptor (basal) · full Type 2 Diabetes pipeline
Afrezza
Marketed by MannKind Corporation
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).
AT278
Developed by Arecor Limited
NCT05754424 · Phase 1 · completed
Every participant received AT278 and the active comparator insulin in random order, with neither participants nor staff knowing which was given at each visit, which is a solid design. But the trial measured a pharmacology lab readout rather than a real-world blood sugar or complication outcome. Registry results were not posted at the time of grading; the key result shown was recovered from the cited external source.
