The HESI GTTC is pleased to share its newest publication, “Error-corrected next-generation sequencing to advance nonclinical genotoxicity and carcinogenicity testing,” published in Nature Reviews Drug Discovery. The commentary highlights the potential applications, advantages and challenges associated with implementing this emerging technology in nonclinical safety studies.

The article will be open access until 25 January 2023.

Quantitative in vitro to in vivo extrapolation of genotoxicity data provides protective estimates of in vivo dose

Environmental and Molecular Mutagenesis

Read More

The Beal et al. (2023) paper is the first of many to come as output of GTTC’s In Vitro Working Group (WG) first phase of efforts towards critically evaluating NAMs for in vitro genotoxicity testing. The WG is also evaluating NAMS through the lens of exposure, metabolism, indirect genotoxicity and the identification of aneugens. This paper provides additional confidence in the use of IVIVE for deriving points of departure (PODs), showing that in vitro PODs are health protective relative to in vivo PODs.

Establishing a Quantitative Framework for Regulatory Interpretation of Genetic Toxicity Dose-Response Data: MOE (Margin of Exposure) Case Study of 48 Compounds with both in vivo Mutagenicity and Carcinogenicity Dose-Response Data

Environmental and Molecular Mutagenesis

Read More

The GTTC’s Quantitative Analysis Workgroup recent publication focuses on the quantitative relationships between carcinogenic potency and mutagenic potency. The group built off the previous benchmark dose (BMD)-based approach by analyzing the carcinogenicity-derived and genotoxicity-derived margin of exposure values (MOEs) from human exposure data of 48 compounds. The findings showed that regulatory decisions based on in vivo genotoxicity dose–response data would be consistent with those based on carcinogenicity dose–response data. Hence in the future, and in the absence of carcinogenicity data, using the in vivo genotoxicity assays could be used to prioritize substances for risk management.

RECENT EVENTS

HESI Board of Trustees Meeting

Read More

The HESI Board of Trustees met in-person on January 17th and 18th to review 2022 achievements and HESI scientific portfolio, approve a 2023 organizational budget, progress the strategic initiatives and conduct a mini-retreat on Board engagement.

HESI is currently achieving a breadth of reach and impact unlike any prior time in its organizational history. Dr. Syril Pettit, HESI Executive Director, pointed to the organization’s ability to set and then achieve goals as evidenced by the significant and rapid progress HESI has made in gaining grant funding, launching new Board-authorized strategic initiatives, and expanding its global reach via programs and membership. She concluded that, via the people who comprise HESI’s Board, staff, and programs, HESI has the opportunity to even further advance the public health impact of HESI’s portfolio.

HESI’s Board of Trustees is comprised of 15 public sector representatives and 14 private sector representatives. We are proud to work with this group of amazing scientists and thank them for their commitment to HESI and HESI’s mission of developing science-based solutions for a safer, more sustainable world.

What a great start to the year it was to welcome our Board of Trustees to our DC offices this month! With Trustees traveling from South America, Africa, Europe, and across North America it was a thrill to have everyone together. The room was filled with discussion about opportunities to further enhance HESI’s global reach, further diversify our resource and partner base, and amplify the beneficial health impact of our work. I’d like to offer a special thanks to our staff and program leaders who worked so hard this year to build out novel strategic initiatives like the Global Risk Assessment Training Center (GRATC), Thrive, and Health DataWell. We have always been an organization focused on translating research into application, but we are now an organization also focused on bringing accessible and fit for purpose tools and methods to stakeholders in need around the globe. These efforts will improve quality of life and human and environmental health – and what could be better than that?

With best regards,

 

Syril Pettit, DrPH, MEM, HESI Executive Director
