About Non-Cystic Fibrosis Bronchiectasis

Non-cystic fibrosis bronchiectasis (NCFBE) is a severe, chronic and rare disease characterized by abnormal dilatation of the bronchi and bronchioles, frequently associated with chronic lung infections. It is often a consequence of a vicious cycle of inflammation, recurrent lung infections, and bronchial wall damage. NCFBE represents an unmet medical need with high morbidity and mortality that affects more than 150,000 people in the U.S. and over 200,000 people in Europe. NCFBE patients who have chronic infections with P. aeruginosa have a 6.5-fold increase in hospitalization, three times higher mortality, and a worse quality of life compared with those without P. aeruginosa infections. There is currently no drug approved for the treatment of this condition.
