1989
HESI holds first workshop on Mouse
Liver Tumors. This workshop was the
first in a series jointly hosted by HESI,
ILSI RSI, and the US EPA. The
outputof these workshops was foundational
in informing the International
Program on Chemical Safety (IPCS)
conceptual framework for evaluating
chemical mode of action.
1989
HESI was founded as a
worldwide environmental
sciences division within ILSI.
(First meeting held
April 5, 1989)
1992
HESI launches its
first four technical
committees.
1992
Dr. Denise Robinson
appointed as HESI’s
first Scientific Director.
1992
HESI launches its first four technical committees:
Carcinogenicity Technical Committee
Immunotoxicology Technical Committee
Water Quality Technical Committee
Waste Management Technical Committee
HESI ITC’s role is unique in that it facilitates
tri-partite collaborations. It is very responsive to
‘grass-roots’ proposals and therefore has a unique
ability to efficiently address questions raised by
bench scientists with a good understanding of big
picture questions, and it provides strong project
management with managers that are also good
scientists. For instance, the ITC played an important
role conveying that one CRA assay does not fit all –
that flexibility in assay design is good. The ITC
impacts contributors’ careers by providing growth
opportunities and increasing expertise.”
Dr. Hervé Lebrec, Amgen
Dr. Denise Robinson
Dr. Robinson worked as the inaugural Executive Director of HESI from
1992 – 2002, during which time she established much of HESI’s initial
governance and programmatic infrastructure. During her tenure,
Dr. Robinson greatly increased the number of active programs, HESI
membership, and global reach. Dr. Denise Robinson earned her PhD in
Pharmacology from Georgetown University School of Medicine. After
leaving HESI, Dr. Robinson worked as the head of Science and
Technology, Drug Safety R&D at Pfizer for over ten years. She is currently
retired and resides in Connecticut, while continuing to devote time to
professional organizations such as the Society of Toxicology.
1993
HESI takes an early lead in exploring non-animal
methods for safety assessment with the launch
of the Alternatives to Animal Testing (AAT)
Technical Committee. The Committee’s research,
with expert guidance from international safety
assessors, ophthalmologists, and vision researchers,
contributed to the abandonment of the in vivo
Draize eye test in favor of in vitro approaches.
1995
The Water Quality Technical Committee
holds a three-day workshop on
Disinfection By-Products in Drinking
Water with support from the US EPA, US
NIEHS, UK Water Industry Research
Council, Chlorine Institute, and the
American Water Works Association.
1996
The Developmental and Reproductive
Toxicology (DART) Committee launches
with an initial project focused on
conducting extensive literature reviews
on non-traditional developmental toxicity
endpoint measurement approaches.
1997
The HESI Peroxisome Proliferation
Activated Receptor (PPAR) Committee
rapidly launches a blinded pathology
review study to address emerging
concerns about potential carcinogenicity
of drugs and chemicals with this
mechanism of action.
1999
HESI celebrates its 10
year anniversary with
~100 supporting
organizations (about
half private sector
and half public
sector). To see

1995
The Water Quality Technical Committee
holds a three-day workshop on Disinfection
By-Products in Drinking Water with support
from the US EPA, US NIEHS, UK Water
Industry Research Council, Chlorine
Institute, and the American Water Works
Association resulting in a comprehensive
textbook on best practices for protecting
human health.
1996
The Developmental and Reproductive Toxicology
(DART) Committee launches with the goal of
conducting extensive literature reviews on
non-traditional developmental toxicity endpoint
measurement approaches. Since its inception,
DART has gone on to publish dozens of
fundamental, peer-reviewed studies and original
research that form the basis for best practices
for DART assessment of chemicals and
drugs worldwide.
Several publications that came from the
HESI-DART committee (2nd species papers;
inhibin B paper; micro-CT evaluations of
skeletons) were extremely useful to our
organization and the regulatory
environment surrounding our activities.
The 2nd species paper and micro-CT papers
were useful to demonstrate the importance
of rabbits in developmental toxicity testing
and the validity of using micro-CT
evaluations in toxicity studies,
respectively."
Dr. Dinesh Stanislaus, GlaxoSmithKline
1997
The HESI Peroxisome Proliferation Activated
Receptor (PPAR) Committee rapidly launches a
blinded pathology review study to address
emerging concerns about potential
carcinogenicity of drugs and chemicals with this
mechanism of action. The study results were
published in a
foundational paper that still informs
human relevance evaluation for
hemangiosarcomas observed in safety studies.
This project pointed out to me how issues
that had urgency could be addressed
quickly through the HESI process, again
bringing together international experts
from government, academia, and industry.
It also pointed out the success of HESI in
being able to handle logistical and scientific
issues in an expeditious manner,
addressing the specific needs of the
sponsors and committee members."
Dr. Samuel Cohen,
University of Nebraska Medical Center
2001
HESI is incorporated as an
independent 501(c)(3)
nonprofit charitable
organization with its own

multiple international awards
for reducing animal usage and
enhanced testing efficiency.
2000
HESI's active scientific committees:
Alternatives to Animal Testing
Alternatives to Carcinogenicity Testing
Developmental and Reproductive Toxicology*
Immunotoxicology*
The HESI role in the Alternatives to
Carcinogenicity Testing project was a great
example of the power of the model and the
ability of this model to foster evolution of
scientific thinking in an area critical to
promoting human health. There were many
individuals involved in making this project a
success and it was the environment created by
HESI that enabled this remarkable cross-
functional effort to be so effective. It is clearly a
model that has been perpetuated and enabled
continuing contributions to the many
challenges we face.”

The
Technical Committee on Agricultural Chemical
Safety, a multi-sector, international group of
government, academic, and industry scientists,
completes a multi-year project to develop an
improved testing scheme for assessing the safety
of crop protection chemicals. The program
receives multiple international awards and
citations for reducing animal usage and enhanced
testing efficiency. Program outputs are
incorporated into tiered testing guidelines across
the globe and reduce overall animal testing.
The Health and Environmental Sciences Institute
(HESI) Agricultural Chemical Safety Assessment
(ACSA) represented an early effort to reduce the
number of animals and resources used in chemical
safety evaluation by designing a tiered testing
paradigm that incorporated existing knowledge of
toxicity and exposure. This effort was an important
springboard to the current efforts to increase the
efficiency and effectiveness of toxicity testing
through use of modern technologies to provide the
most relevant information for decision-making.”
Dr. Vicki Dellarco, U.S. EPA (retired)
2001
The Alternatives to Carcinogenicity Testing
Committee
publishes the results of a multi-year,
30 million dollar study evaluating six distinct
transgenic rodent assays. The results of this
study inform International Conference on
Harmonization guidelines for these assays and
their acceptance by regulatory authorities
including the FDA, EMA, Japan, Health Canada,
and other drug safety agencies around the world.
The success of this project is a strong
recommendation for the tripartite approach
that HESI is promoting. It was decided that
ICH Guideline S1B would give companies
the opportunity to use transgenic mice if
further evaluated. This recommendation
took place after evaluation of the HESI
project and as a consequence, a lot of
companies have replaced the two-year
mouse study.”

Dr. Michael Holsapple
Dr. Michael Holsapple holds a PhD in Pharmacology & Toxicology from
Purdue University and was the Executive Director of HESI from 2002 –
2011. Throughout all stages of his career, Dr. Holsapple has maintained
an interest in immunotoxicology, including the importance of
developmental immunotoxicity testing.

2006
In response to global health concerns about
unanticipated and potentially lethal clinical
arrhythmias associated with marketed drugs,
HESI undertakes a multi-site experimental
program to inform novel safety testing
approaches. The results of this study published
in 2006 -
Hanson et al. – inform novel global
cardiac safety standards and effectively eliminate
the development of drugs with unanticipated
arrhythmic effects.
There is no other place, besides the HESI Cardiac
Safety Committee, where there is this breadth of
expertise and cross-sector partnership focused on an
area of fundamental scientific need. And although we
don’t often think about this because we’re focused on
advancing our pharmaceutical and environmental
safety assessment processes, but cardiovascular
disease is the number one cause of mortality globally.
There are significant public health impacts that can
come from what we study and the capabilities we
develop in this HESI program."
Dr. Brian Berridge,
National Toxicology Program NIH
2004
HESI Genomics Committee publishes its
seminal
evaluation of the use of genomic
microarrays for chemical and pharmaceutical risk
assessment in EHP. These articles have since
received ~500 citations and thousands of
downloads. The effort led to the launch of the first
public microarray database that included
experimental animal data (Tox-ArrayExpress) and
spurred other efforts such as the MAQC
(consortium on genomic data quality) and
contributed to the identification of novel renal and
genetic toxicity biomarkers.
The project wouldn’t have
happened [without HESI]. HESI
brought people together to
collaborate. HESI can bring people
together to do a huge research
project that no one else would do –
this is very valuable."
Dr. Jennifer Fostel, NIEHS / NIH
2006
Challenges and opportunities to enhance
exposure-driven approaches to integrating
biomonitoring data in human health risk
assessment are highlighted in two pivotal
publications in
Environmental Health Perspectivesand
Toxicological Sciences by the HESI
Biomonitoring Committee in 2006. These papers
have been cited hundreds of times in the last ten
years and continue to inform contemporary practice.
2008
The value and limitations of DNA adduct data for
assigning mode of action for tumor development
is the focus of discussions and
publications from
multi-disciplinary international team of safety
scientists within the DNA Adducts Committee.
This program led to the formation of the current
Genetic Toxicology Technical Committee that has
become a global leader in the design and
evaluation of methods of genotoxicity testing.
[Health Canada] fully appreciates the strength of the
tri-partite approach used to advance applications and
uptake of new tools and approaches. The HESI
portfolio within GTTC is impactful, hitting all of the
latest important topics and helping to advance and
improve genetox methodologies. Working together
alongside our industry and academic partners’ issues
and challenges facilitates arriving at consensus. In
addition, much of the work feeds directly into critical
international exercises like revisions of OECD test
guidelines, which are necessary to ensure the
protection of human health.”

The HESI Protein Allergenicity Technical
Committee (PATC) holds a Beijing workshop on
food allergy and safety assessment on protein
allergenicity and toxicity, clinical allergy, and the
safety of genetically modified crops, fostering
future collaborations with Chinese scientists
and regulators.
[The PATC] studies were related to
evaluating the relevance of digestibility as
a determinant of allergenicity and to
assessing whether bioinformatic sequence
comparisons should be based on identity or
similarity. The outcome of these studies
has provided new leads for studies on the
process of sensitization and symptom
elicitation in food allergy, and for studies
on IgE cross-reactivity.”

HESI has been a very effective coordinator for the
different voices of the tripartite membership. This
composition has made the outcome very useful and,
being consensus-driven, reflective of the science
behind the allergy hazard assessment. The usefulness
derives from the efforts to make the COMPARE
Database clearly derived from literature references
with data that meets clear performance goals and are
peer reviewed. I think COMPARE has had a big impact
on how we move forward on the toxin database or
sequence comparisons.”
