Medigene to present first pre-clinical data for MDG1015 with poster presentation at AACR 2023 Annual Meeting

Planegg/Martinsried – 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 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.
