Blood test may help severe COPD patients safely reduce steroids

NCT ID NCT04481555

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study tested a personalized approach for people with severe COPD. Doctors used a simple blood test (eosinophil count) to decide whether to reduce inhaled steroids, and some patients also received the antibiotic azithromycin. The goal was to see if this strategy could reduce serious flare-ups and hospital stays. 444 patients took part, and the results could lead to safer, more tailored treatment plans.

Active substance

azithromycin and inhaled corticosteroids (ICS)

What this could lead to

If successful, this approach could help personalize COPD treatment, reducing unnecessary steroid use and preventing severe flare-ups.
