The present invention provides noncovalent complexes of cationic molecules and adenoviral vectors containing a transgene. The complexes of the invention exhibit increased efficiency of gene transfer to a target cell relative to adenoviral vectors alone. Methods of making and using the complexes are also provided. A method of delivering cystic fibrosis transmembrane conductance regulator to a CF patient utilizing a complex of cationic molecules and adenoviral vectors containing a transgene encoding a CFTR protein is provided.
