This subproject is one of many research subprojects utilizing theresources provided by a Center grant funded by NIH/NCRR. The subproject andinvestigator (PI) may have received primary funding from another NIH source,and thus could be represented in other CRISP entries. The institution listed isfor the Center, which is not necessarily the institution for the investigator.Cystic fibrosis (CF) is a recessive genetic disease, characterized by pulmonary and sinus disease, and gastrointestinal and reproductive tract dysfunction. The disease is caused by mutations in the cystic fibrosis transmembrane regulator (CFTR) gene, which encodes for an apical membrane epithelial protein that functions as a c-AMP-regulated chloride channel and a regulator of other channels (Boucher, 1994). Defective CFTR results in abnormal ion transport and depleted airway surface liquid volume with reduced mucociliary clearance and a propensity for chronic infection of the respiratory tract with resulting inflammation, progressive airway damage and bronchiectasis.New therapies are being developed for the treatment of CF, based on insights into the pathophysiology of the disease. P2Y2 receptor agonists represent a novel approach to the treatment of CF that attempts to bypass defective CFTR in airway epithelia and, instead, take advantage of the integrated actions of this class of agents on mucociliary clearance that are not dependent on CFTR. These agents act by stimulating the P2Y2 receptor, which results in chloride ion (Cl-) and liquid secretion and the inhibition of sodium (Na+) absorption to hydrate the airway surface liquid layer and create a more normal periciliary fluid milieu,while also stimulating mucin secretion from goblet cells and increasing ciliary beat frequency. Denufosol tetrasodium (INS37217) inhalation solution (denufosol) is a novel second generation, chemically stable, selective P2Y2 receptor agonist under development by InspirePharmaceuticals, Inc. Denufosol may have the ability to restore or maintain mucociliary clearance in patients relatively early in the CF lung disease process, which may preserve lung function and lessen the inevitable repeat cycles of pulmonary bacterial colonization, pulmonary exacerbations, and chronic lung function decline.The objective of this study is evaluate the efficacy, safety and tolerability of a 60 mg nebulizer dose of denufosol compared to placebo when administered three times daily over 24 weeks in patients with mild CF lung disease.
