Oncolytic viruses (OVs) are effective anti-cancer agents, however their abilities to induce anti-tumor immunity are not yet optimal. Mutanome epitopes are a novel source of tumor antigen formed as a result of mutations within the tumor genome. Within this project we attempted to combine B16F10 mutanome vaccination with OV therapy. We confirmed previous findings that significant immune responses to these epitopes can be generated. Furthermore, we designed and cloned a multi-epitope mutanome construct into MG1 Maraba virus and E1-/E3- deleted type 5 Adenovirus to use for heterologous prime-boost vaccination. While we demonstrated that these viruses induced T-cell responses to one mutanome epitope, we failed to detect responses to the other epitopes. Furthermore there was no effect seen on overall survival. This approach warrants further investigation because coupling mutanome vaccination with OV therapy has the potential to exploit the therapeutic effects of the OV while inducing anti-tumor immunity to tumor-unique antigens.
