Study description

Cystic fibrosis (CF) is an autosomal recessive disease with serious, chronically debilitating morbidities and high premature mortality, and at present, there is no cure. Cystic fibrosis affects approximately 70,000 individuals worldwide and is caused by mutations in the CF transmembrane conductance regulator gene (CFTR), which result in absent or deficient function of the CF transmembrane conductance regulator (CFTR) protein at the cell surface.Ivacaftor (Kalydeco™, 150-mg tablets) has been approved in the United States, the European Union (EU), Canada and Australia to date, for the treatment of CF in patients 6 years of age and older who have a G551D mutation in the CFTR gene. Ivacaftor is an orally bioavailable small molecule CFTR potentiator that targets the underlying defect in CF. As such, ivacaftor is a member of a new class of drugs - CFTR modulators - that provide a new therapeutic approach to the treatment of CF. Ivacaftor is the first CFTR modulator to show an improvement in CFTR function and clinical benefit in patients with CF.Ivacaftor is intended for chronic, potentially lifelong use. Understanding of the long term effects will be informative to patients and their parents, prescribers, and payers. Existing CF registries provide an established source to obtain long term safety in a real life use for analysis. The patient registries of the CF Trust in the United Kingdom (UK) and the CF Foundation in the United States (US) provide the ideal source to obtain long term safety information because the data collected are extensive and consistent with one another. In addition, the patients with CF from the CF Trust and the CF Foundation patient registries encompass a majority of the patients in the indicated population.Cystic fibrosis patient registries from France and Ireland were considered for this study and will be used for drug utilization analysis.
