Authors' conclusion

While there are limitations to the interpretation of results from a study using RWD, it is reassuring that there was no increase in pulmonary toxicity attributable to inhaled TI for treatment of diabetes with respect to lung cancer, COPD, emphysema, and chronic bronchitis.

Study context

Population
Individuals with diabetes in the Epic Cosmos database, prescriptions between January 1, 2015, and October 8, 2024, >365 days between first and last prescription; excluded if increased risk of pulmonary disease before or within 1 year postindexmatched 3:1
Participants
647 vs 1,830
Exposure
Inhaled technosphere insulin vs rapid-acting analogue insulin
  • Technosphere insulin (TI)n = 647
  • Rapid-acting analogue (RAA)n = 1,830reference
Outcome
Diagnosis codes for lung cancer, chronic obstructive pulmonary disease (COPD), emphysema and chronic bronchitis
Follow-up
At least 1 year after the index date
