NCT ID NCT07255430
First seen Jan 05, 2026 · Last updated Jun 23, 2026 · Updated 32 times
Summary
This study looks at 160 children with protracted bacterial bronchitis (PBB), a condition causing long-term cough. Researchers will analyze samples from the children's airways to understand the mix of bacteria and viruses, how the immune system responds, and how the standard antibiotic treatment (azithromycin) affects these factors. The goal is to learn more about the disease and improve future treatments.
