Safety and Immunogenicity of Recombinant DNA and Adenovirus Expressing L523S Protein in Early Stage Non-Small Cell Lung Cancer

The primary objective of the study is to evaluate the safety of the vaccine regimen
administered as two doses of pVAX/L523S and two doses of Ad/L523S.

The secondary objectives of the study are:

- To provide initial evidence as to whether CD8+ and CD4+ T cell responses specific for
L523S protein can be elicited by two doses of pVAX/L523S followed by two doses of
Ad/L523S

- To provide initial evidence as to whether antibody responses specific for L523S protein
can be elicited by two doses of pVAX/L523S followed by two doses of Ad/L523S

- To investigate the extent to which dose escalation of Ad/L523S affects the elicited
immune response
