Fraunhofer ITEM offers comprehensive toxicological expertise for the testing and safety assessment of chemicals, pharmaceuticals, and medical devices – ranging from exposure characterization and the generation of toxicological data to regulatory consulting and support throughout approval and registration processes. A particular focus lies on inhalation toxicology and the realistic characterization of inhalable substances. State-of-the-art exposure technologies enable the efficient use of very small substance quantities in toxicological studies.

Human-based models and innovative testing strategies

Toxicological research at Fraunhofer ITEM is consistently aligned with the ethical 3R principle. The targeted use of alternative, human-based test systems reduces animal testing while increasing the relevance of results for humans. Established and continuously advanced human in vitro and ex vivo models – including precision-cut lung slices (PCLS) and other human or humanized organ models – are also applied to the testing of biopharmaceuticals and advanced therapy medicinal products (ATMPs).

Next generation risk assessment (NGRA)

In addition to classical toxicology, which remains the regulatory standard, Fraunhofer ITEM contributes to the development of new assessment strategies through its own research projects based on the concept of next generation risk assessment. The aim is to provide predictive models for modern, efficient, and animal-free safety evaluation.

Toxicological effect assessment is supported by omics technologies such as metabolomics and functional genomics, combined with advanced bioinformatic analyses. Database-driven approaches, including the threshold of toxicological concern (TTC), are further developed, for example to identify non-genotoxic carcinogens or to adapt these concepts for applications in the field of medical devices.

RISK-HUNT3R project

For next generation risk assessment of toxic effects, human-based testing strategies are being developed to reduce, refine and, wherever possible, replace animal testing. 

 

Toxicological risk assessment for PFAS

At Fraunhofer ITEM, we are investigating how PFAS impact people’s health. Our main objective here is to separate the PFAS family into subclasses according to their structures and physical and chemical properties, and use this as a basis for determining limits for safe amounts of ingestion for each subclass. 

REGENERAR

The EU project REGENERAR explores epigenetic approaches to brain regeneration. Fraunhofer ITEM researchers are evaluating the safety of nanoparticle-based therapies.
