SIMPLIFY: Study to evaluate stopping inhaled hypertonic saline or dornase alfa in people with CF who are taking the triple-combination modulator, elexacaftor/tezacaftor/ivacaftor, protocol number SIMPLIFY-IP-19

This study will test the effects and safety of stopping inhaled hypertonic saline or dornase alfa (Pulmozyme®) in teens and adults with CF who are also taking the triple-combination modulator, elexacaftor/tezacaftor/ivacaftor (Trikafta®). Trikafta® is intended to help CFTR function closer to normal, resulting in better clearance of mucus from the lungs. Inhaled hypertonic saline and dornase alfa are intended to thin airway surface liquid and improve clearance of mucus from the lungs. They are considered to be relatively burdensome therapies, so this study will look at the impact of stopping them in people who are also taking Trikafta®.
