NCATS Tox21 Data Challenge 2014

The National Center for Advancing Translational Sciences (NCATS) announces the Toxicology in the 21st Century (Tox21) Data Challenge 2014 competition. The Tox21 Data Challenge 2014 is a crowdsourcing competition to develop computational models that can better predict chemical toxicity. The Tox21 initiative is designed to improve current toxicity assessment methods, which are slow and costly.

Registration for the challenge and for more information, please click here.

The model submission deadline is Nov. 14, 2014, 11:59 p.m. ET. NCATS will showcase the winning models in January 2015.

EPA Modifies Second List of EDSP Screening Chemicals

In November 2010, EPA developed a second list of chemicals for screening and draft policies and procedures for the Agency’s use to require testing of chemicals for Tier 1 screening. On June 14, 2013, EPA issued a revised second list of chemicals and revised policies and procedures for screening SDWA chemicals, including the statutory requirements associated with and format of the test orders, as well as EPA’s procedures for fair and equitable sharing of test costs and data confidentiality.

Update on EPA’s Endocrine Disruptor Screening Program

At the June 2014 meeting of the Pesticide Program Dialogue Committee, EPA presented an EDSP Update.  EPA’s PowerPoint presentation is available here.

NAS/NRC Publishes Review of EPA Paper on NMDRs

The National Academy of Science’s National Research Council has published its report entitled: Review of the Environmental Protection Agency’s State-of-the-Science Evaluation
of Nonmonotonic Dose–Response Relationships as They Apply to Endocrine Disruptors. This NAS/NRC report has obvious implications for EPA’s Endocrine Disruptor Screening Program.  Click here for report.

This report includes the following conclusions:

 “Recommendation: An analytic plan should be developed and applied consistently to the evidence on the three hormone pathways. Important elements of the plan include predefining and documenting the literature-search strategies and their results, establishing criteria for selecting studies for analysis, establishing criteria for determining study quality, using templates for presenting evidence consistently in tabular and graphic form, and documenting approaches to integration of evidence. Guidance on these elements is provided below [in following sections of the report].”

NAS Report on EPA and NMDR Now Scheduled for May 2014

The National Academy of Science’s National Research Council is reviewing EPA’s draft paper State of the Science on Nonmonotonic Dose Response.  This review has EDSP implications.  For example, some public comments to the Committee criticized EPA’s approach to the EDSP. Committee staff told CRE that publication of the Committee report on its review probably won’t occur until May 2014. The project website is available by clicking here.

EPA Beta Testing EDSP Online Response Module

EPA is developing a fully electronic, Web-based submission system to handle responses to future Endocrine Disruptor Screening Program  test orders.

During the week of April 21, 2014, EPA will be conducting Industry Beta Testing of the response module. This test will allow industry participants to access the test module and provide feedback on the response module prior to the tool’s launch. This feedback will be key to the successful development of this and future electronic submission systems. This beta testing was previously scheduled for the week of March 31, 2014.
