New Approach Methods in Safety AssessmentEU-ToxRisk Solutions

Who we are

The EU-ToxRisk Commercial Partnership is a joint venture between organisations providing coordinated integrated solutions to industrial problems in safety assessment. The partners bring experience and resources together to provide a one-stop shop in safety assessment solutions.

We jointly have experience in New Approach Methodology in safety assessment, predictive toxicology, in vitro screening, computational modelling, toxicogenomics, read across, tiered strategies, data science, product design, risk assessment and regulatory assessment.

What we provide

Solutions to:

  • Tiered strategies in safety assessment
  • Evaluation of toxicological endpoints: e.g., liver, kidney, neurotoxicity, skin, eye, endocrine disruption
  • Integrated screening and data analysis across multiple technologies
  • High quality best practices in protocols, data generation and processing
  • Data mining and modelling to supporting decision making and jobs to be done
  • Product ingredient screening and evaluation
  • Formulation testing and assessment
  • Animal free safety assessment
  • Read Across
  • Risk Assessment
  • Regulatory reporting

Adverse Outcome Pathways (AOPs)

  • Knowledge-mining of background information and documents to propose AOP key events, related hypotheses and testing strategies
  • In vitro and toxicogenomics testing and analysis of AOP-based hypotheses

Testing

  • Our in silico modelling and in vitro testing workflows are anchored to key events of Adverse Outcome Pathways (AOPs)
  • Our testing is guided by in silico modelling e.g. we can provide a business case for testing based on the value of new information generated
  • We can carry out exhaustive searches of existing databases, public knowledge sources, and document repositories using data and knowledge mining techniques supported by expert curation capabilities as required

Modelling

  • We can apply a variety of algorithms and machine learning techniques to datasets supporting the building of reference and customised models
  • For skin sensitization we have reproduced the leading defined approaches developed and used at industry leaders leaders such as P&G, BASF, Givaudan and Shiseido and including a well-documented and easy-to-use comparison of model results
  • We also can apply our computational chemistry expertise to the evaluation of properties such as metabolism and transporters
