Summary

This study is enrolling 200 adults with asthma or COPD to see if combining chest CT scans with blood, sputum, and microbiome tests can more accurately tell the two diseases apart. Researchers will also look for clues that predict how well a patient will respond to treatment. No experimental drugs are involved—the goal is to improve diagnosis and personalize care.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If successful, this could lead to a more accurate way to diagnose asthma versus COPD and help doctors choose the right treatment for each patient.
What could go wrong
This is an observational study, not a treatment trial. The results may not lead to immediate changes in care, and the findings might not apply to all patients.
