An adenoviral vector comprising (a) an adenoviral genome deficient in the E4 region of the adenoviral genome, (b) a nucleic acid sequence coding for TNF, and (c) a radiation inducible promoter operably linked to the nucleic acid sequence coding for TNF. This invention also provides an adenoviral vector comprising (a) an adenoviral genome deficient in the E4 region of the adenoviral genome, (b) a nucleic acid sequence coding for TNF, and (c) a spacer element of at least 15 base pairs in the E4 region of the adenoviral genome. A method of producing an adenoviral vector and a method of treating a tumor or cancer in a host comprising administering an anti-cancer or anti-tumor effective amount of the adenoviral vector of the present invention also is provided. |
