Good In Vitro Method Practices Certification: A Roadmap for Implementation and Harmonization

October 7, 2022
The Organization for Economic Cooperation and Development (OECD) guidance document on Good In Vitro Method Practices (GIVIMP) details a set of quality standards to improve both the quality of and confidence in newly developed, and routinely executed in vitro methods. Currently a practical guide to implement GIVMP standards is missing; leaving organizations to define the best approach for themselves. ...

IIVS is Pleased to Announce the Co-Publication of Three Articles

August 25, 2022
IIVS is pleased to announce the co-publication of several respiratory-based articles highlighting: the characterization and recommendations for non-animal techniques used to model mucociliary clearance in human-derived test systems, the dosimetry of tobacco products for in vitro testing and a third article covering the use of New Approach Methodologies to nicotine containing products in a regulatory environment. Key Challenges for In Vitro Testing of Tobacco Products for Regulatory applications: Recommendations for Dosimetry Ciliary Beat Frequency: Proceedings and Recommendations from a Multi-laboratory Ring Trial Using...

May 2022 Newsletter

The ability to ascertain the maximum limit of a compound that can be applied to the skin without inducing skin sensitization is a critical safety criterion for virtually any risk assessment. Using regression models developed by Givaudan (Kempthal, Switzerland), IIVS is able to perform a computational approach to determine predicted EC3 values (Effective Concentration required to induce a 3-fold upregulation of lymph node cell proliferation) using a combination of OECD approved assays (KeratinoSens, hCLAT, and kDPRA). This value can be used to assess risk for compounds to...

Evaluating the Use of Predictive Models in Combination with In Vitro Assays

April 11, 2022
IIVS is excited to announce the publication of 2 papers evaluating the use of predictive models in combination with in vitro assays to provide a quantitative assessment of skin sensitization potential. This work is presented Drs. Frank Gerberick (GF3 Consultancy, Chief Scientific Advisor to IIVS) and Andreas Natsch (Senior Research Fellow at Givaudan ) Integrated Skin Sensitization Assessment Based on OECD Methods (I): Deriving a Point of Departure for Risk Assessment Integrated Skin Sensitization Assessment Based on OECD Methods(II): Hazard and Potency...

Use of alternative test methods in a tiered testing approach to address photoirritation potential of fragrance materials

January 3, 2022
Happy New Year! IIVS is pleased to greet 2022 with the announcement of a joint publication with the Research Institute for Fragrance Materials (RIFM) involving the evaluation of photoirritation potential of over 100 compounds. This effort, spanning the course of 7 years, involved a tiered testing approach with the application of 3 OECD test guidelines: TG 101, 432 and the recently accepted 498, which codifies the acceptance of Reconstructed human Epidermis as a model for assessing this endpoint.
