Mainz/Martinsried/Munich, Germany, February 21, 2022 – BioNTech SE (Nasdaq: BNTX, “BioNTech”) and Medigene AG (FSE: MDG1, Prime Standard, “Medigene”), a clinical-stage immuno-oncology company focusing on the development of T cell immunotherapies, today announced that they have entered a multi-target research collaboration to develop T cell receptor (TCR) based immunotherapies against cancer. The initial term of the collaboration is three years.
Medigene will contribute its proprietary TCR discovery platform for the development of TCRs against multiple solid tumor targets nominated by BioNTech. Medigene’s automated, high throughput TCR discovery platform is designed to bypass central tolerance to yield high affinity TCRs. T cell therapy has become a disruptive medical innovation in the treatment of patients with cancer. Engineered TCR-modified T cells (TCR-T cells) are reprogrammed to express a TCR that can recognize specific antigens only present on tumor cells, thereby enabling a precise and potent immune response to attack a patient’s tumor.
“This collaboration with Medigene expands our cell therapy portfolio and TCR discovery capabilities, and further strengthens our ability to be a leader in the rapidly emerging field of engineered cell therapies,” said Ugur Sahin, M.D., Chief Executive Officer and Co-Founder of BioNTech. “We look forward to working closely with Medigene to develop new treatments which address solid tumors with high unmet medical need.”
Prof. Dolores Schendel, Chief Executive Officer and Chief Scientific Officer at Medigene: “Medigene is at the forefront of the development of TCR-T therapies for oncology. The sale and licensing deal with BioNTech is an important validation from a global leading biotech company of our proprietary technologies to discover and characterize highly specific TCRs and empower resulting TCR-T cells to fight solid tumors. This partnership provides Medigene with meaningful financial resources to fuel our next generation development programs targeting potentially novel tumor-specific “dark matter” antigens, further tools to enhance T-cell-based immunotherapies, as well as additional potential strategic deals with future milestone payments and royalties.”
BioNTech will acquire Medigene’s next generation preclinical TCR program, which combines TCR-4 of Medigene’s MDG10XX program targeting PRAME with Medigene’s proprietary PD1-41BB switch receptor technology. BioNTech will also obtain the exclusive option to acquire additional existing TCRs in Medigene’s discovery pipeline and will receive licenses to the company’s PD1-41BB switch receptor and precision pairing library. This has the potential to augment TCR cell therapy efficacy and can be applied to all BioNTech cell therapy programs.
Under the terms of the agreement, Medigene will receive EUR 26 million upfront, as well as research funding for the period of the collaboration. BioNTech will be responsible for global development and hold exclusive worldwide commercialization rights on all TCR therapies resulting from this research collaboration. Medigene will be eligible to receive development, regulatory and commercial milestone payments up to a triple digit million EUR amount per program in addition to tiered deferred option payments on global net sales for products based on TCRs arising from the collaboration and royalties on products utilizing at least one of the licensed technologies.

About Medigene’s TCR-T cells
T cells are at the center of Medigene’s therapeutic approaches. With the aid of Medigene’s immunotherapies the patient’s own defense mechanisms are activated, and T cells harnessed in the battle against cancer. Medigene’s therapies arm the patient’s own T cells with tumor-specific T cell receptors (TCRs). The resulting TCR-T cells should thereby be able to detect and efficiently kill cancer cells.
This approach to immunotherapy aims to overcome the patient’s tolerance to cancer cells and tumor-induced immunosuppression by activating the patient’s T cells outside the body, genetically modifying them with tumor-specific TCRs and finally multiplying them. In this way, large numbers of specific T cells are made available to patients to fight the cancer within a short period of time.
About Medigene’s PD1-41BB switch receptor
Checkpoint inhibition via PD1-PDL1 pathway: Solid tumor cells are known to be sensitive to killing by activated T cells. Tumor cells can escape this killing activity by expressing inhibitory molecules, so-called ‘checkpoint proteins’, such as Programmed Death Ligand 1 (PD-L1) on their surface. When this occurs, activated T cells which express PD-1, the natural receptor for PD-L1, are inactivated. The expression of PD-L1 by tumors represents an adaptive immune resistance mechanism that can lead to tumor survival and growth.
The 4-1BB co-stimulatory signaling pathway: Effective T cell immune responses to antigens typically require costimulatory signals to be received alongside the primary antigenic stimulation via the T cell receptor (TCR). The intracellular signaling domains of the 4-1BB protein offer a well-characterized pathway to positively enhance T cell responses.
Medigene’s PD1-41BB switch receptor takes advantage of the binding of PD-1 on the T cells to PD-L1 on tumors. In the switch receptor, the inhibitory signaling domain of PD-1 has been substituted with the activating signaling domain of 4-1BB. As a result, the switch receptor then delivers an activating signal to the TCR-T cells (not the usual inhibitory signal of PD-1). This enables the PD1-41BB-modified TCR-T cells to proliferate strongly in the presence of PD-L1-positive tumor cells and to mediate greater killing of tumor cells upon repeated exposure. Additionally, signals mediated through the switch receptor also enhance metabolic fitness of TCR-T cells, enabling better function in conditions of low levels of glucose or high levels of the immunosuppressive factor TGFß, two conditions that are characteristic of strongly hostile tumor microenvironments.
About Medigene’s precision pairing library
T cell receptors (TCRs) consist of an alpha and a beta chain, which together act as a receptor on the cell surface of T cells. Medigene's therapies aim to equip the patient's own T cells with tumor-specific TCRs. The resulting TCR-T cells should thereby be able to detect and efficiently kill cancer cells.
The precision pairing library allows selection of specific modifications in each chain of a TCR so that the alpha and beta chains preferentially pair with each other, with the result that improved TCR surface expression and/or functionality is achieved.
