The combination of this single Inhibigen with the otherwise-protective vaccine abrogated vaccine efficacy and returned tumor growth to levels of unvaccinated mice. The Inhibigen-associated effects included dampening of T cell immune responses as early as four days after a single dose, and a reversal of the infiltration of both lymphoid and myeloid populations into the tumor microenvironment. These data suggest that Inhibigen-specific responses not only dampen systemic immunity, but also revert tumor microenvironments to an immune-cold state \u2013 a feature of early-stage tumor growth.<\/p>\n<p>\u201cOur data add to a growing body of preclinical and clinical evidence confirming that\u00a0Inhibigens\u00a0are not innocent bystanders, but\u00a0rather\u00a0they\u00a0can reverse the beneficial effects of cancer immunotherapies,\u201d said Hanna Starobinets, a scientist at Genocea and lead presenter at the AACR meeting. \u201cWhile Genocea continues to exclude Inhibigens from its immunotherapy candidates, ongoing studies aim to further allow us to understand and overcome immunotherapy resistance.\u201d<\/p>\n<p>Genocea previously demonstrated that Inhibigen vaccination could stifle immune responses to other antigens co-formulated in a vaccine, and that the effect could not be reversed through combination therapy with immune checkpoint inhibitors (ICI).

Our proprietary ATLAS\u2122 platform comprehensively profiles each patient\u2019s T cell responses to potential targets, or antigens, on that patient\u2019s tumor. ATLAS zeroes in on both antigens that activate anti-tumor T cell responses and inhibitory antigens, Inhibigens\u2122, that drive pro-tumor immune responses. We are advancing two ATLAS-enabled programs: GEN-009, our neoantigen vaccine for which we are conducting a Phase 1\/2a clinical trial and GEN-011, our adoptive T cell therapy using neoantigen-targeted peripheral cells for which we are commencing a Phase 1\/2a clinical trial. In addition to our two clinical programs, we are conducting research in several areas where we believe ATLAS could be a key tool in identifying meaningful therapies.
