Methods and compositions for treatment of interferon-resistant tumors
The present invention provides a method for the treatment of interferon resistant tumors through the use of recombinant vectors encoding interferon species. In particular it is noted that interferon species provided by recombinant vectors possesses properties not associated with the recombinantly produced interferon proteins. The present invention further provides compositions useful in the treatment of interferon resistant tumors using recombinant vectors encoding interferons.
1. A method of treating an interferon-resistant lung cancer by contacting said cancer with a recombinant vector encoding an interferon.
2. The method of claim 1 wherein said recombinant vector is an adenovirus.
3. The method of claim 2 wherein said adenovirus is replication deficient.
4. The method of claim 3 wherein said interferon is an interferon α.
5. The method of claim 4 wherein said interferon alpha is selected from the group consisting of interferon α2b, interferon α2a, and interferon α2α1.
6. The method of claim 1 wherein cells of said interferon-resistant lung cancer have been exposed to an enhancing agent.
7. The method of claim 6 where in the enhancing agent is Syn3.
8. The method of claim 7 wherein said vector and sand enhancing agent are administered together.
9. The method of claim 7 wherein said interferon is interferon α2b.
10. The method of claim 7 wherein said vector and sand enhancing agent are administered contemporaneously.
11. The method of claim 7 wherein said vector is administered within an hour after administering the enhancing agent.
12. The method of claim 7 wherein said vector and said enhancing agent are administered by inhalation.
13. The method of claim 7 wherein said vector and said enhancing agent are administered intralesionally.
