The OSIRIS Project (1 Apr 2007 – 30 Sep 2011)

The new regulation concerning the registration, evaluation, authorisation and restriction of chemicals (REACH) requires demonstration of the safe manufacture of chemicals and their safe use throughout the supply chain.

While REACH is based on the precautionary principle, it includes also the aim to reduce animal testing where possible.

Aims of OSIRIS

The goal of the project OSIRIS was to develop integrated testing strategies (ITS) fit for REACH that enable to significantly increase the use of non-testing information for regulatory decision making, and thus to minimise the need for animal testing. To this end, operational procedures were developed, tested and disseminated that guide a transparent and scientifically sound evaluation of chemical substances in a risk-driven, context-specific and substance-tailored manner.

For the first time, an ITS has been equipped with a decision theory framework including alternative methods such as chemical and biological read-across, in vitro results, in vivo information on analogues, qualitative and quantitative structure-activity relationships, thresholds of toxicological concern and exposure-based waiving. OSIRIS took into account cost-benefit analyses, and it aimed to close the gap between risk and societal risk perception. It was based on the new REACH paradigm to move away from extensive standard testing to a more intelligent, substance-tailored approach.

The work was organised in the five interlinked research Pillars

- Chemical Domain,
- Biological Domain,
- Exposure,
- Integration Strategies and Tools,
- Case Studies
,

with a particular focus on more complex, long-term and high-cost endpoints. Case studies demonstrate the feasibility and effectiveness of the new ITS methodologies, and provide guidance in concrete form.

To ensure optimal uptake of the results obtained in this project, end-users in industry and regulatory authorities were closely involved in monitoring and in providing specific technical contributions to this project.

Major Outcome

The research of OSIRIS focussed in the following ITS

- Skin Sensitisation,
- Repeated Dose Toxicity,
- Mutagenicity & Carcinogenicity,
- Bioconcentration Factor,
- Aquatic Toxicity


A public report on these ITS and other important OSIRIS results will be available here from January 2012. Overview journal publications on the single ITS will be prepared.

More than 100 papers in peer-reviewed journals present the individual results achieved within OSIRIS:

The

allows to follow the developed decision trees online. It is supported by the local QSAR and database system

Both software tools are publicly available for free.

OSIRIS Finished

The official end of the project was reached in September 2011. We thank all partners for their excellent cooperation. The public report giving an overview on the major achievements has been submitted to the European Commission. For legal reasons, please ask them in case you are interested in obtaining a copy. There are still OSIRIS related publications on their way. The OSIRIS publication page will still be updated, thus you may watch it regularly. However, this news column will no more be updated.
