Phase I Pilot Study of Ad5-CB-CFTR, an Adenovirus Vector Containing the Cystic Fibrosis Transmembrane Conductance Regulator Gene, in Patients With Cystic Fibrosis

OBJECTIVES: I. Assess the safety and efficacy of gene transfer into the nasal epithelium using Ad5-CB-CFTR, an E1-deleted adenovirus vector containing the cystic fibrosis transmembrane conductance regulator gene, in patients with cystic fibrosis (CF). II. Determine whether ion transport abnormalities in CF airway cells can be corrected.
