Medigene announces publication in "Nature Biotechnology" on TCR-development

Press release

Martinsried/Munich, 17 March 2015. Medigene AG (MDG1, Frankfurt, Prime Standard) announced that a scientific article on T cell receptors with optimal affinity to cancer antigens has been published in the current issue of the renowned journal "Nature Biotechnology" (doi:10.1038/nbt.3147 - published online 16 March 2015). The positive research results presented show an important scientific foundation for the clinical development of the TCR-based T cell therapy approach.

Prof. Thomas Blankenstein, Director of the Institute for Immunology at the Charité - Universitätsmedizin Berlin and working group leader at Max Delbrück Center for Molecular Medicine (MDC) Berlin: "We are very pleased that our intensive efforts of the past are now coming to fruition and open the door to provide new T cell-based immunotherapies for cancer patients."

Prof. Dolores J. Schendel, Chief Scientific Officer of Medigene AG: "This publication represents results from a long-standing alliance of teams in Berlin and Munich to develop tools and technologies to engineer patient lymphocytes to effectively attack their own tumours."

The article titled "Identification of T cell receptors with optimal affinity to cancer antigens using antigen-negative humanized mice" http://www.nature.com/nbt/journal/vaop/ncurrent/full/nbt.3147.html
outlines the extensive pre-clinical developments regarding the identification of these specific T cell receptors.

The results have been generated in a research alliance between Prof. Thomas Blankenstein, Director of the Institute for Immunology at the Charité - Universitätsmedizin Berlin and working group leader at Max Delbrück Center for Molecular Medicine (MDC) Berlin in close cooperation with Prof. Dolores J. Schendel, now Chief Scientific Officer of Medigene AG. This alliance is supported since 2006 by the German Research Foundation of which Medigene Immunotherapies is a formal member.

About Medigene`s T cell receptor- (TCR) modified T cells: This therapy approach aims to utilize the body`s own machinery - the T cell - to target and destroy cancer by arming normal patient-derived T cells with new T cell receptors that enable them to detect and efficiently kill tumour cells. This form of immunotherapy is designed to overcome a patient`s tolerance to cancer since the T cells of the patient are activated and modified outside the body, away from generalized immune suppression in the patient. Compared to small molecule or antibody based therapies this approach can be used for new targets to fight tumours. A large army of specific T cells is made available to patients within a short period of time. The therapy is potentially suited for the treatment of advanced cancer.
