Summary
This study follows people with cystic fibrosis who are taking a highly effective medication called elexacaftor/tezacaftor/ivacaftor (ETI). Participants use a mobile app to report their daily symptoms, medication use, and any changes in their health over 12 months. The goal is to understand how the treatment performs in real-world settings, outside of a clinic.
