Replication competent adenovirus (RC-Ad) vectors mediate robust transgene expression by virtue of amplifying transgenes by replication, but also put patients at a risk of frank adenovirus infection. In contrast, E1-deleted replication defective Ad (RD-Ad) vectors are safer, but produce substantially less transgene product. To generate a robust, but safer adenoviral vector, we created a “single cycle" adenovirus (SC-Ad) vector that replicates its genome and transgene, but that does not cause adenovirus infections by deleting the capsid cement protein IIIa in low seroprevalence adenovirus serotype 6. Ad6-ΔIIIa can be produced in IIIa-expressing cell lines. In normal cells, Ad6-ΔIIIa replicates its genome and transgene, but fails to package its DNA or form mature virus. SC-Ad and RC-Ad expressed transgenes hundreds of times higher than RD-Ad in human and mouse cells in vitro and in vivo in mice. These data suggest that SC-Ads may be safer amplifying vectors for vaccine and therapeutic applications.
