Medigene presents streamlined 6-day, high stemness TCR-T therapy production process - Seite 2

Multiple in vitro studies for MDG1015 have clearly demonstrated enhanced anti-tumor immune responses for MDG1015 in comparison to TCRs without the CSP. This enhancement is evidenced by increased TCR-T cell proliferation and marked augmentation of Interferon γ (IFNγ) release, serving as a reliable indicator of superior TCR-T cell functionality. Furthermore, MDG1015 showed elevated polyfunctionality and clear durability of effect, with rapid and sustained tumor cell eradication upon multiple serial rechallenges of CTA / PD-L1 positive cells.

IND/CTA approval for MDG1015 is expected in the second half of 2024. Clinical indications for MDG1015 were primarily chosen based on the high unmet medical need, expression of the target antigen and/or PD-L1. This led to the selection of gastric cancer, ovarian cancer, myxoid/round cell liposarcoma, and synovial sarcoma as the initial focus areas for clinical evaluation. First patient enrolment will follow by the end of 2024, subject to financing. Based on this, the Company expects to present early data from the dose escalation phase in the fourth quarter of 2025.

About Medigene AG

Medigene AG (FSE: MDG1) is an immuno-oncology platform company dedicated to developing differentiated T cell therapies for treatment of solid tumors. Its End-to-End Platform is built on multiple proprietary and exclusive technologies that enable the Company to generate optimal T cell receptors against both cancer testis antigens and neoantigens, armor and enhance these T cell receptor engineered (TCR) -T cells to create best-in-class, differentiated TCR-T therapies, and optimize the drug product composition for safety, efficacy and durability. The End-to-End Platform provides product candidates for both its own therapeutics pipeline and partnering. Medigene’s lead TCR-T program MDG1015 is expected to receive IND/CTA approval in the second half of 2024. For more information, please visit https://medigene.com/

About Medigene’s MDG1015 Program

MDG1015 is a first-in-class, 3rd generation T cell receptor engineered T cell (TCR-T) therapy targeting NY-ESO-1 / LAGE-1a, a well-recognized and validated cancer testis antigen, which is expressed in multiple tumor types. MDG1015 contains our optimal affinity 3S (sensitive, specific and safe) NY-ESO-1 /LAGE-1a TCR combined with our proprietary PD1-41BB costimulatory switch protein that blocks the PD1/PD-L1 inhibitory axis while simultaneously activating the T cell through the well described 4-1BB pathway further enhancing the activity and persistence of the TCR-T cell in the hostile tumor microenvironment (TME). MDG1015 is currently undergoing IND/CTA enabling studies with IND/CTA approval expected in the second half of 2024.
