A phase I clinical trial was conducted in which recombinant adenovirus containing the cystic fibrosis trans-membrane regulator (CFTR) (Ad2/CFTR) was administered by bronchoscopic instillation or aerosolization to the lungs of cystic fibrosis (CF) patients. In this paper, we evaluate the efficiency of Ad2/CFTR-mediated transduction of bronchial airway cells. The ability of an Ad2/CFTR vector to transduce airway cells was first evaluated in patients to whom the vector was administered by bronchoscopic instillation. Cells at the administration site were collected 2 days after treatment by bronchoscopic brushing. Ad2-specific CFTR DNA was detected in four of five individuals by PCR, and Ad2-specific CFTR RNA was detected in three of five individuals by RT-PCR. Ad2/CFTR-mediated transduction of airway epithelial cells was then determined in CF individuals receiving this vector by aerosol inhalation. Ad2-specific CFTR DNA was detected in 13 of 13 individuals 2 days after aerosolization, and in 3 of 5 individuals 7 days after aerosolization. Ad2-specific RNA was detected in 4 of 13 individuals on day 2, but was not detected in the 5 individuals tested on day 7. The percentage of airway epithelial cells containing nuclear-localized vector DNA was < or =2.4% as determined by fluorescence in situ hybridization (FISH). However, in some cases, a high percentage of nonepithelial mononuclear cells or squamous metaplastic epithelial cells was infected with the adenoviral vector. In conclusion, aerosol administration is a feasible means to distribute adenoviral vectors throughout the conducting airways, but improvements in adenovirus-mediated transduction of airway epithelial cells are necessary before gene therapy for CF will be effective.
