REACH Study for Cystic Fibrosis Without Modulators

The REACH study is for people with Cystic Fibrosis (CF) who are not currently taking CFTR (cystic fibrosis transmembrane conductance regulator) modulators. This observational study aims to collect health information and samples from 400 participants to help researchers understand CF better and develop new treatments for those who can't use modulators. The study also wants to learn about how people with CF who don't take modulators get involved in research. Success in this study will be measured by changes in ppFEV1 (percent predicted forced expiratory volume in 1 second, a measure of lung function) over 12 months. The current recruitment status is unclear.
