Head-to-head evidence
Afrezza vs SHR-3167
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).
SHR-3167
Developed by Jiangsu Hengrui Pharmaceuticals
NCT06688123 · Phase 2 · completed
The study used randomization and an active insulin glargine comparator in 275 participants, but it was open-label rather than blinded. Its primary endpoint was change in HbA1c, a surrogate measure, and no results are currently available to show whether the primary comparison was met.
