Neon Therapeutics Provides Business Update and Outlook for 2019


CAMBRIDGE, Mass., Jan. 03, 2019 (GLOBE NEWSWIRE) -- Neon Therapeutics, Inc. (Nasdaq: NTGN), a clinical-stage immuno-oncology company developing neoantigen-based therapeutics, today provided a business update and outlook for 2019.

“We have an exciting year ahead of us in 2019, with multiple data readouts from our personal neoantigen vaccine program, NEO-PV-01, in a variety of metastatic cancer settings using a number of rational treatment combinations. We are also continuing to investigate monotherapy opportunities and look forward to sharing our plans later this year,” said Hugh O’Dowd, Neon’s Chief Executive Officer.

“We expect the upcoming data readouts to include correlations between mechanism of action and clinical response and enable development of later-stage trials that will draw on treatment combinations and target patient populations most likely to benefit from our personal cancer vaccine,” said Richard Gaynor, M.D., Neon’s President of Research and Development.

Neon also continues to advance its T cell programs, including the development of a library of high-quality TCRs. “I expect these programs to become increasingly important in 2019, as we continue to build a diversified clinical-stage pipeline,” Mr. O’Dowd said.

With regard to its personal neoantigen T cell program, NEO-PTC-01, Neon continues to build on data presented at the Society for the Immunotherapy of Cancer 2018 Annual Meeting. The Company plans to file a European Clinical Trial Application (CTA) in the first half of 2019 to enable it to initiate a first-in-human clinical study of NEO-PTC-01, which is being developed in collaboration with the Netherlands Cancer Institute (NKI). 

“Data from our ongoing research give us added confidence that we can reliably generate multiple enriched neoantigen-specific T cell populations that are capable of killing tumor cells,” said Dr. Gaynor. “We believe NEO-PTC-01 has several significant advantages that could overcome the challenges of other cell therapies in the solid tumor setting and we look forward to evaluating this approach in checkpoint refractory patients.”

John Haanen, M.D., Ph.D., Professor and Head of the Medical Oncology Division at the NKI, remarked: “We are excited to be working with Neon to initiate the first neoantigen adoptive T-cell clinical trial that seeks to elicit both de novo and memory T cell responses across a range of solid tumors in patients that are refractory to checkpoint inhibitors.”

With respect to TCRs, Neon has been leveraging its RECON® bioinformatics engine to identify shared neoantigen epitopes and its NEO-STIM™ induction protocol to generate neoantigen-reactive T-cell receptors to these epitopes. Drawing on this work, Neon has assembled libraries of high-quality TCRs against various shared neoantigens across common HLAs.

“Our maturing T cell programs will join our vaccine programs in developing new paradigms for the treatment of solid tumors,” said Dr. Gaynor.
