Cystic fibrosis (CF) is one of the most common life-threatening genetic disorders worldwide. At the very centre of this debilitating disease is a defect in the cystic fibrosis transmembrane conductance regulator (CFTR) – a membrane protein that plays an important role in ion exchange and water balance throughout the body. CFTR modulators were recently developed to target and overcome errors in CFTR and in doing so, represent the first disease-modifying treatment for CF.
