Proportions of inhibitory neoantigens found in cancer patients with the ATLAS™ biology-driven platform may also predict patient responses to immunotherapy
Confirm positive GEN-009 clinical immunogenicity results
CAMBRIDGE, Mass., Nov. 05, 2019 (GLOBE NEWSWIRE) -- Genocea Biosciences, Inc. (NASDAQ: GNCA), a biopharmaceutical company developing next-generation neoantigen immunotherapies, today announced preclinical and clinical data demonstrating that ATLAS™ can identify relevant neoantigens and exclude inhibitory neoantigens that suppress anti-tumor immune responses at the 34th Annual Meeting of the Society for Immunotherapy of Cancer (SITC), taking place from November 6 – 10, 2019 in National Harbor, Maryland. ATLAS is Genocea’s unique platform that profiles each patient’s T cell responses to every candidate neoantigen to select those driving pre-existing anti-tumor responses. Additional data will also be presented, demonstrating that inhibitory neoantigen profiles may predict if a patient will respond to immunotherapy and confirming broad immune response data for the company’s novel neoantigen therapy GEN-009.
“Our preclinical findings represent exciting and powerful new discoveries in the role that inhibitory neoantigens play in response to immunotherapies,” said Tom Davis, M.D., Chief Medical Officer, Genocea. “Through these data, we demonstrate the power of the ATLAS platform to identify and target only those neoantigens with a high propensity to drive anti-tumor responses while excluding inhibitory, immunosuppressive antigens. We are also pleased to share additional GEN-009 results, which round out the GEN-009 clinical immunogenicity data set from our initial patient cohort and confirm the relevance of these preclinical findings in advancing patient treatment.”
The following posters will be located in Prince George's Exhibition Halls AB. Odd-numbered posters will be presented on Friday, November 8th from 12:30 – 2:00 p.m. ET and 6:30 – 8:00 p.m. ET, and even-numbered posters will be presented on Saturday, November 9th from 12:35 – 2:05 p.m. ET and 7:00 – 8:30 p.m. ET.

About Genocea Biosciences, Inc.
Genocea is a biopharmaceutical company developing personalized cancer immunotherapies. Our unique ATLAS™ technology platform allows us to identify targets based on each person’s tumor antigen-specific T cell responses. Using ATLAS, we can both optimize neoantigens for inclusion in our immunotherapies and exclude inhibitory antigens that exert an immunosuppressive effect on anti-tumor immune responses. We are advancing complementary programs built from ATLAS insights: GEN-009, our neoantigen vaccine candidate for which we are conducting a Phase 1/2a clinical trial across a variety of solid tumor types, and GEN-011, our neoantigen-specific adoptive T cell therapy, for which we intend to file an Investigational New Drug Application in the first half of 2020.
