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.
What this could mean

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.
What could go wrong
This is a completed Phase 4 trial, but results may not apply to all COPD patients. Azithromycin can cause antibiotic resistance and side effects like hearing loss or heart rhythm issues.
