Transgene, a biotech company that designs and develops virus-based immunotherapies for the treatment of cancer, NEC Corporation, a leader in IT and network technologies, and BostonGene Corporation, a biomedical software company committed to defining optimal precision medicine-based therapies for cancer patients, today announced a strategic collaboration for two ongoing Phase 1 clinical trial of TG4050, an individualized therapeutic vaccine for ovarian and head & neck cancers based on Transgene's proprietary myvac(R) platform and NEC's AI-driven Neoantigen Prediction System in Europe and the United States.

Transgene's myvac(R) platform brings together a series of highly innovative technologies, such as viral genome engineering, to achieve high-speed modular manufacturing of bespoke immunotherapies.

TG4050 is an individualized cancer vaccine based on the myvac(R) platform; it is based on an optimized viral platform for cancer vaccination and integrates NEC's artificial intelligence capabilities. This therapeutic vaccine aims at stimulating the immune system of patients to induce a T-cell response against tumor-specific antigenic alterations, called neoantigens. These neoantigens are derived from genomic mutations and selected using NEC's Neoantigen Prediction System, an advanced AI technology that has already been applied in the field of oncology. TG4050 has been designed to target up to 30 patient-specific neoantigens. Transgene is sponsoring two Phase 1 trials that are expected to deliver a first proof of concept of this virus-based individualized approach.

As part of the collaboration, BostonGene will conduct genomic and transcriptomic analyses of primary patient tumours collected from patients enrolled in these two clinical trials to identify predictors of response to TG4050 and the cancer cell-intrinsic and -extrinsic factors that may mediate each patient's response to the vaccine. BostonGene's platform integrates the genomic and transcriptomic analyses to simultaneously assess the activity of the tumour and the
microenvironment through the identification of significant somatic alterations, evaluation of gene expression, estimation of tumour heterogeneity and classification of the microenvironment.

BostonGene generates a Tumor Portrait(TM) Report, involving the data-driven, visually appealing and self-explanatory tumour schematics elegantly depicting tumour activity, tumour cellular composition, and functionality of the immune-microenvironment and other tumour-associated processes. The comprehensive report will provide insights into the individual oncogenic state and immunogenicity of the patient's tumour.

"BostonGene's unique solution and deep expertise in Next Generation Sequencing (NGS) analysis provide us with the detailed profiles of a tumour and its micro-environment. These Tumor portraits? Reports will help us look at our patient data in light of the current published evidence and could help us accelerate the development of TG4050," said Eric Quemeneur, Pharm.D., Ph.D., Executive VP, Chief Scientific Officer of Transgene. "This novel way of analyzing patient data is part of an ambitious translational program that supports the development of our myvac(R) platform. By integrating these types of approaches into our studies, we seek to build an integrated framework for the use of viral-based immunotherapeutics."

"NEC looks forward to strengthening its collaboration with BostonGene through these trials of TG4050. BostonGene's advanced analysis of NGS among cancer patients provides excellent profiling that we believe will add important insight into the understanding of each patient's tumour environment and how it reflects on the clinical outcomes of our treatment," said Osamu Fujikawa, Senior Vice President at NEC Corporation.

"BostonGene is proud to support Transgene and NEC during these critical Phase 1 clinical trial," said Nathan Fowler, MD, Chief Medical Officer at BostonGene. "This collaboration represents our ongoing commitment to improve immunotherapy options and transform personalization of treatment for cancer patients."
