Highlight
- Dupilumab significantly reduces total mucus plug number and volume in moderate to severe asthma patients as seen on CT imaging.
- Individual mucus plugs resolve more frequently and new plug formation is markedly decreased following dupilumab treatment compared to controls.
- Radiodensity of persistent and new mucus plugs exhibits a notable decrease post-dupilumab, implying qualitative changes in mucus composition.
- Improvements in mucus burden correspond with enhanced lung function metrics, including FEV1 and ventilation assessed by 129Xe MRI.
