Fraunhofer ITEM is one of 76 institutions of the Fraunhofer-Gesellschaft, Europe's leading organization for applied research. Headquartered in Hannover (Germany) and with additional facilities in Braunschweig and Regensburg, the institute aims to protect man from health hazards in our industrialized world and to contribute to the development of novel therapeutic approaches.
The Fraunhofer ITEM division in Regensburg is dedicated to Personalized Tumor Therapy and has a special expertise in the isolation and characterization of disseminated or circulating cancer cells. Circulating tumor cells (CTC) are isolated, for example, by taking simple blood samples (referred to as “liquid biopsy”), whereas disseminated cancer cells (DCC) can be isolated from lymph node tissue or bone marrow. These rare cells are subject to in-house, advanced next-generation multi-omics sequencing technologies and bioinformatic data analysis to reliably analyze the comprehensive genetic information at the single-cell level. Further expertise includes the analysis of cell-free, tumor-derived blood components (circulating tumor DNA, microvesicles) and innovative tissue-based analytical methods (tissue biopsy). Additionally, supported by a large clinical network, Fraunhofer ITEM in Regensburg is developing workflows for rare-cell expansion and has already established a multitude of in-vitro/in-vivo models based on DCC or CTC from various tumor entities. These preclinical models are used for high-throughput screening of substances and RNAi/CRISPR libraries to identify active agents and targets to gain a better functional understanding of DCC and CTC biology and of their response to therapy. This provides new opportunities not only for molecular diagnostics in precision oncology, but also for the investigation of pathophysiological processes in rare driver cells.
In addition, ex-vivo models developed by the institute’s Division of Preclinical Pharmacology and Toxicology in Hannover offer a novel opportunity to study early stages of metastasis and primary human tumors. Precision-cut tissue slice (PCTS) systems either from tumor tissue or peripheral organs co-cultured with tumor cells enable the investigation of human tissue-derived immune reactions, for instance key events of immune tolerance to tumor cells or early colonization events in metastasis. This facilitates testing of treatments such as gene therapy, checkpoint inhibitors or cell therapeutics with regard to their mode of action, targeting, efficacy and toxicity in an organotypic human setting.
The particular value of such a model is based on 1) human background, addressing the complexity of the appropriated microenvironment, 2) patient-specificity of the tumor cells in order to reflect tumor heterogeneity, 3) immune competence to assess the tolerance-inducing mechanisms, and 4) applicability of molecular and cellular manipulation and analysis tools.
Research on personalized tumor therapy is one of several key topics at Fraunhofer ITEM. Focusing on lung and inhalation, the institute’s divisions in Hannover and Braunschweig have pooled their expertise in three business units:
In the business unit Drug Development, we develop and test novel medications against respiratory diseases (including lung cancer). Scientific expertise covers manufacturing of biologics such as therapeutic antibodies, preclinical and clinical development.
The business unit Chemical Safety is dedicated to determining the risks from potentially harmful substances. Scientific expertise includes toxicology testing, exposure assessment, analytical methods, regulatory research and risk assessment.
The business unit Translational Biomedical Engineering offers many years of experience in the development of medical devices – specifically neural implants and medical aerosolizers – including testing and testing scenarios, safety and risk assessment.
All business units offer regulatory support.
Numerous test systems are available, including in-vitro, ex-vivo and in-vivo. Studies can be performed in compliance with GXP regulations.
