New study pits two asthma inhalers Head-to-Head using advanced lung imaging

This study aims to see which of two triple-combination inhalers works better for people with moderate to severe asthma that is not well controlled. About 20 adults will try both Trimbow and Trelegy Ellipta in a crossover design, and researchers will use special MRI scans to measure how well the drugs reach different parts of the lungs. The goal is to find out if one inhaler improves lung ventilation more than the other.
