The study's main goal is to observe how effective elexacaftor-tezacaftor-ivacaftor is for improving the symptoms and signs of CF-related sinus disease.


To determine if elexacfator-tezacaftor-ivacaftor improves the signs and symptoms of CF-related sinus disease, before and after initiation of triple combination therapy, each subject will undergo sinus CT scan and complete questionnaires related to signs and symptoms of sinus disease.
