Production of a document on good in vitro practices in collaboration with the European Commission and the OECD.
The document went into the second public consultation round:



Background information: There is a scientific policy and regulatory desire for validated and internationally accepted in vitro methods (e.g. OECD test guidelines or ISO standards). To accommodate the needs of regulatory authorities, a number of in vitro methods, often based on the use of human cells and tissues, have been submitted to international validation bodies during the last two decennia. However, the experience gained during these validations revealed that many in vitro methods need significant improvements in design, robustness and reliability before they can be successfully implemented in a routine laboratory environment to generate data sets, which can be used to support regulatory decisions. GIVIMP specifies these improvements.

Workshop on ‘developmental and reproductive toxicity (DART) test methods’

The workshop was held in collaboration with BASF and CAAT-Europe in the historical concilium building. International experts worked on a roadmap for improved DART testing to support development of new compounds, reduce the use of animals, and increase safety of the population

Publication of our first screening paper to identify unknown toxicants together with the National Toxicology Program, USA (NTP) and the Computational Toxicology unit at University of Pompeu Fabra (Barcelona). We define strategies for ‘hit’ (= positive screen result) confirmation and hit follow-up in the field of toxicology.

Publication of a large systems toxicology-oriented review on the MPTP Parkinson’s disease model, together with leading experts involved in the initial discovery of the underlying toxicant (D. DiMonte, DZNE, Bonn), and  in contemporary landmark discoveries concerning new mechanisms (K. Tieu, Miami).

 The EFSA opinion ‘A new path to toxicity assessment’ is officially published


We worked hard on this, and on the embedded adverse outcome pathway (AOP) examining a relevant link of pesticides and Parkinson’s disease (link)
