AOP News - March 2020
The Society for Advancement of Adverse Outcome Pathways had recent election for two open positions. Dan Villeneuve was elected Vice President and Jason O’Brien was elected Councillor.
- The JRC now has a contract in place to facilitate the transition to AOP-KB 2.0. This contract will allow any needed updates and maintenance of the current AOPWiki, and it includes the deployment of a dedicated development and testing server that will serve as a test bed for changes prior to moving them to the production server.
- The EPA has hired a part time programmer to help with gardening activities on the AOPWiki. Current efforts are focused on updating the status of all AOPs
Upcoming Meetings/Symposia/Workshops/Training on AOPs
- The QSAR 2020 meeting will be held in Durham North Carolina from June 8 -11. And it includes a training session entitled “AOP Hands-on Training: Building the Foundation for Predictive Toxicology”. https://www.ascctox.org/qsar2020/qsar-2020-program
- The Human Toxicology Project Consortium and Physicians Committee for Responsible Medicine will once again co-sponsor an ancillary session on AOPs at the Society of Toxicology’s (SOT) annual meeting in Anaheim, CA: What AOPs can do for you: an introduction and hands-on experience, Hilton Anaheim, 4:45pm - 6:45pm, Mar 16, 2020.
Past Meetings/Symposia/Workshops/Training on AOPs
- An AOP training was held on 25 Feb 2020 at the US FDA as part of an internal in-person and webinar series on NAMs. About 70 FDA scientists participated.
- An AOP-Wiki and AOP-DB training for ORD AOP Research Area contributors was held November 15th, 2019, in conjunction with the yearly AOP-Knowledgebase meeting in Research Triangle Park, NC.
- Chemical Watch’s CHCS Training “Advanced Toxicology” Module 11 (March 4, 2020) will provide advanced training day in toxicology that includes the use of AOPs in interpreting data when there is a toxicological concern. https://www.chcs.org.uk/event-3576429
- Also see links below for online training sites
ChemicalWatch published two articles about AOPs in 2019
- In July 2019, ChemicalWatch published an article about the AOP Framework Study facilitated by the JRC.
- In April 2019, ChemicalWatch published an article on how scientists from US EPA and Environment and Climate Change Canada have networked existing adverse outcome pathways (AOPs) to reveal thousands of potential new toxicity mechanisms.
The Food Packaging Forum published a short note about the ChemicalWatch report on JRC’s AOP Survey https://www.foodpackagingforum.org/news/survey-on-adverse-outcome-pathways
OECD NEWS (Contact: Magda Sachana Magdalini.SACHANA@oecd.org )
AOP developers are encouraged to submit their AOPs to be considered in the OECD AOP Programme. Here is a link to the form to submit an AOP Project proposal.
The AOP workplan is updated in June and December of every year
The OECD released three webinar video recordings on Adverse Outcome Pathways:
1) Adverse Outcome Pathways Framework, 30 April 2019
This first webinar on Adverse Outcome Pathways (AOPs) discussed the Adverse Outcome Pathway (AOP) framework. The AOP framework is a collaborative tool that applies an innovative approach for collecting mechanistic knowledge from various sources that can eventually support chemical safety assessment.
2) Adverse Outcome Pathways: Assembling and evaluating weight of evidence and quantitative understanding - 15 January 2020
This second webinar on Adverse Outcome Pathways (AOPs) focused on the importance of weight of evidence in the process of developing AOPs, the types and lines of evidences assembled, examples demonstrating the lines of evidence and understanding why quantitative AOPs are developed. The AOP framework is a collaborative tool that applies an innovative approach for collecting mechanistic knowledge from various sources that can eventually support chemical safety assessment.
3) Adverse Outcome Knowledge Base (AOP-KB) and AOP developing tips - 30 January 2020
The third webinar on Adverse Outcome Pathways (AOPs) focused on the core information and telecommunication technologies applications that were built to support AOP development, management, and dissemination. Tools and technical tips to facilitate scientific knowledge assembly and evaluations were also presented. The AOP framework implements a collaborative and innovative approach for collecting mechanistic knowledge from various sources that can eventually support chemical safety assessment.

New AOPs published by OECD: Following Joint Meeting declassification, seven AOPs were published in July 2019 on the OECD Series on Adverse Outcome Pathways.
JRC AOP Framework Analysis
The JRC has launched an AOP Framework study, which will analyse the framework's suitability to address regulatory priorities and support regulatory processes and decision-making. The focus of the study will be the AOP users, i.e. regulatory toxicologists, risk assessors and risk managers. An online survey will help to identify ca. 75 suitable telephone interviewees, from which 10-15 stakeholders will be selected to form a focus group. The focus group will then examine the study in-depth (on-site, with advanced ethnological methods) to arrive at observations and suggestions to adapt the framework to best meet stakeholder needs. The results of the study will be available by February 2020
