Martinsried/Munich, March 16, 2023. Medigene AG (Medigene, FSE: MDG1, Prime Standard), an early stage immuno-oncology platform company focusing on the discovery and development of T cell immunotherapies for solid tumors, will present a poster at the American Association for Cancer Research Virtual Annual Meeting (AACR) 2023 being held on April 14-19, 2023.

The work to be presented shows that T cells carrying a NY-ESO-1-specific T cell receptor (TCR) combined with a chimeric PD1-41BB switch receptor, have significantly increased TCR-T cell proliferation, functionality and anti-tumor activity, compared to T cells expressing the TCR alone. A potential mechanism associated with this enhanced functionality is the greater release of multiple different effector cytokines.

The abstract for this research has been published online at https://www.abstractsonline.com/pp8/#!/10828/presentation/3341 and posters will be available online on April 18, 2023.

About Medigene’s TCR-T Therapy Platform
Medigene’s immunotherapies help activate the patient’s own defense mechanisms by harnessing T cells in the battle against cancer. Medigene’s end-to-end platform combines multiple exclusive and proprietary technologies to create best-in-class TCR-T therapies. The platform includes multiple product enhancement technologies, (e.g. PD1-41BB Switch Receptor, Precision Pairing) and development optimization technologies (e.g. Allogeneic-HLA (Allo-HLA) TCR Priming) to aid the development of differentiated TCR-T therapies. Partnerships with multiple companies including BioNTech, 2SeventyBio, and Hongsheng Sciences, continue to validate the platform’s assets & technologies.

About Medigene’s MDG1015 Program
MDG1015 is a 3rd generation T cell receptor engineered T cell (TCR-T) therapy targeting NY-ESO-1, a well-recognized and validated cancer testis antigen which is expressed in multiple tumor types. MDG1015 contains our high-avidity, NY-ESO-1 TCR combined with our proprietary PD1-41BB co-stimulatory switch receptor that blocks the PD1/PD-L1 inhibitory axis while simultaneously activating the T cell through the well described -41BB pathway further enhancing the activity and persistence of the TCR-T in the hostile tumor microenvironment (TME). MDG1015 is currently undergoing IND/CTA enabling studies.
