Neon Therapeutics to Present at the American Association for Cancer Research Annual Meeting

CAMBRIDGE, Mass., Feb. 27, 2019 (GLOBE NEWSWIRE) -- Neon Therapeutics, Inc. (NTGN), a clinical-stage immuno-oncology company developing neoantigen-based therapeutics, today announced upcoming presentations at the American Association for Cancer Research (AACR) Annual Meeting, taking place March 29 – April 3, 2019 in Atlanta, GA.

At the AACR meeting, Neon will be presenting data relating to both its personal neoantigen vaccine, NEO-PV-01, and its personal neoantigen T cell therapy, NEO-PTC-01. Data from the NEO-PV-01 program will include correlative analysis from the melanoma cohort in NT-001, a clinical trial exploring the feasibility, safety, efficacy and immunogenicity of NEO-PV-01 dosed in combination with nivolumab in patients with advanced or metastatic melanoma, non-small cell lung cancer and bladder cancer. Mature clinical outcomes from this study will be presented later in the first half of this year.

“We have been closely tracking multiple metrics of patients’ immune response following dosing with our NEO-PV-01 vaccine and are looking forward to presenting correlative analysis with data from the melanoma cohort at AACR,” said Richard Gaynor, M.D., President of Research and Development at Neon Therapeutics.

“With regard to our NEO-PTC-01 program, we are pleased to be presenting updated data that demonstrate that NEO-STIM™, our proprietary ex vivo co-culture process using peripheral blood mononuclear cells, can consistently generate multiple enriched neoantigen-specific T cell populations.  We have also demonstrated that these cells are capable of killing tumor cells. These findings support the feasibility of advancing this program into the clinic,” concluded Dr. Gaynor.  

Details for the oral presentation are as follows:

Presentation Title: The personalized vaccine, NEO-PV-01 with anti-PD1, induces neoantigen-specific de novo immune responses in patients with advanced metastatic melanoma: Association with clinical outcomes 
Session Title: Cancer Vaccines and Intratumoral Immunomodulation
