Immunomic Therapeutics, Inc. today presented late-breaking preclinical data which shows that its investigational nucleic acid platform, UNITE, may enhance antitumor immunity when used in connection with its investigational DNA vaccine, ITI-7000. In preclinical studies, ITI-7000, an investigational DNA vaccine targeting ErbB2/HER2, demonstrated robust activation of known anti-tumor CD4 and CD8 cells in vivo and promoted tumor infiltration with activated CD8 T cells. These data are presented today at the American Association for Cancer Research (AACR) 2019 meeting in Atlanta, Georgia.

In addition to observing activation of known anti-tumor CD4 and CD8 cells in vivo, Immunomic scientists observed the overexpression of PDL1 in the tumor microenvironment. This pathway has shown clinical relevance as a cancer immunotherapy target of the tumor microenvironment. PDL1 overexpression upregulated by ITI-7000 suggests that a combination of ITI-7000 with an anti-PD1/PDL1 therapy may increase the therapeutic potential of either agent on its own. This data also supports the prevailing belief in the immunotherapy community that cancer vaccination could synergize with anti PD1 and PDL1 and other immunotherapies, as well as support the viability of the UNITE platform as a means to do so. In summary, these findings support the potential of ITI-7000 as a cancer vaccine and highlight that UNITE, Immunomic’s nucleic acid platform, may have the potential to enhance immunity of investigational cancer therapies.
