ANAHEIM, Calif.--(BUSINESS WIRE)--Gilead Sciences, Inc. (Nasdaq:GILD) today announced detailed results of its Phase III AIR-CF1 (CP-AI-007) study of aztreonam lysine for inhalation, an investigational therapy in development for the treatment of people with cystic fibrosis (CF) who have pulmonary Pseudomonas aeruginosa (P. aeruginosa). In this study, a 28-day treatment course of aztreonam lysine improved respiratory symptoms as assessed by the Cystic Fibrosis Questionnaire-Revised (CFQ-R), a patient-reported outcome (PRO) tool. Aztreonam lysine also improved pulmonary function in this study, as measured by relative improvement of forced expiratory volume in one second (FEV1), a standard measure of lung function. The data were presented by George Z. Retsch-Bogart, MD, Associate Professor of Pediatrics at the University of North Carolina, Chapel Hill, at the 21st Annual North American Cystic Fibrosis Conference (NACFC) in Anaheim, California. Topline results from this study were previously announced on May 29, 2007.
