Could a common antibiotic tame severe asthma in kids?
NCT ID NCT06223828
First seen Jun 25, 2026 · Last updated Aug 12, 2026 · Updated 3 times
Summary
This study tests whether azithromycin, an antibiotic, can reduce airway inflammation in children ages 3-17 hospitalized for critical asthma. One hundred participants will receive the drug for three days while researchers monitor inflammation markers and side effects. The goal is to see if this treatment can shorten ICU stays and improve recovery.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- azithromycin (an antibiotic that may also reduce inflammation)
- What this could lead to
- If it works, this could offer a short, safe treatment to help children recover faster from severe asthma attacks and reduce time in the ICU.
- What could go wrong
- This is an early-phase, open-label study with no placebo group, so results may be less reliable. Azithromycin can cause side effects like stomach upset or heart rhythm changes.
