Abstract:

Recombinant adenoviral vectors have been used as gene delivery or expression vehicles in multiple therapeutic applications such as gene therapy, vaccines, or CRISPR. In vaccine research and development, gene expression via adenoviral vector constructs have been shown to be effective in enhancing T-cell responses against several viral infections or endogenous viruses causing malignancy. We will present data from novel therapeutic vaccine candidates based on the hAd19a/64 vector designed to target an extended set of antigens to fight diseases such as HPV induced cervical and oropharyngeal cancers. Furthermore, in combination with chemotherapeutic drugs, the vaccine effect was enhanced. In addition to elicitation of CD4+ and CD8+ T-cells reported from prior research, in our studies the effect of the novel vaccine and chemotherapeutic drug resulted in an increased infiltration of dendritic cells into the tumor. Design and development of the novel vaccine candidate with extended antigen repertoire within adenoviral backbone will be presented.
