WHY DO WE NEED TO COLLECT THIS DATA? Cost of drug and chemical development • New medicines could be identified from “old” data • Using this “free” data will cut the cost and time to market • Those old reports hold useful data for future benefits
The 3Rs • Each animal test creates data that is valuable not just for the safety or efficacy testing
of the test article that it was exposed to, but also for the potential part that it can play within computational toxicology and replacement of further animals and/or tests

Significant legislation has been passed covering different industries by agencies and governments including • 7th Amendment to the Cosmetics Directive (EC 2013) • REACH (ECHA 2016) • Frank R. Lautenberg Chemical Safety for the 21st Century Act (US Safe
Chemicals Act) Resulting in a goal to reduce the amount of animal testing needed for each safety evaluation using alternative methods and to encourage data sharing amongst companies and stakeholders In vitro and computational models and new ways of interpreting these data are all encouraged

Industry wide nonclinical to clinical database was created to determine how safety assessments in animal models translate to First-In-Human clinical risk Blinded database containing 182 molecules, animal toxicology data and clinical observations from phase I human studies The analysis supported the current regulatory paradigm of animal testing in supporting safe entry to clinical trials
This confirms the utility of using this data in computational models

CAN COMPUTATIONAL TOXICOLOGY MODELS BE BUILT?
Yes, but • The model is only as good as the data entered • The data is only as good as the technicians and scientists • The quality can only be guaranteed by quality procedures

LHASA LIMITED – QSAR COMPUTATIONAL MODELS
A good example is the products generated by companies such as Lhasa • Data is identified & harvested from many sources; peer review journals,
provided by private companies or available on public websites • Data is graded based on it’s source, quality processes, information etc. The model is only as good as the data entered!!!
Other providers include, but not limited to: Simulations Plus, Leadscope

WHAT ARE THE BLOCKERS TO CREATING THESE MODELS?
The critical blockers are • IP • Competition • Confidentiality
• Business • Intellectual • Scientific • “Chemical”
• Ontology
But, we also need to consider • Cost • Time constraints

![Page 15: Gaining Access to Large Quantities of Standardized Animal ......data.eNanoMapper.net is a public database hosting nanomaterials characterization data and biological and toxicological](https://reader034.vdocument.in/reader034/viewer/2022042408/5f22fcf94a0c4860122a33e0/html5/thumbnails/15.jpg)

IP, COMPETITION AND CONFIDENTIALITY
These are, on the surface, the insurmountable barriers. • Why loose IP to a competitor? • What happens if a company discovers a blockbuster drug using data
generated from a rival company? • Does the rival have a claim to this molecule?
But, benefits s hould be considered to evaluate if they outweigh these costs • IP and confidentiality will be retained by legal agreements • Companies are already sharing data

ENANOMAPPER
eNanoMapper was an FP7 EU funded project completed in January 2017 • It delivered data and computational infrastructure; it was not a data
generation project instead data was provided by other projects (https://search.data.enanomapper.net/enm/)
• Later, the NANoREG project used the eNanoMapper database to transfer nanosafety data generated by 60 partners under open license (https://search.data.enanomapper.net/nanoreg_about.html)
OK, but what about industry with competition and IP to consider?

GAINING ACCESS TO HIGH QUALITY DATA

WHAT IS THE DEFINITION OF HIGH QUALITY DATA?
Published in a peer review journal? • What quality processes were incorporated into this research project? • What was the quality of the peer review? • Was the work performed GLP-like? Generated under GLP? • Is there a national accreditation scheme? • Is there regular auditing by authorities?
I digress, so I define Quality Data as generated under GLP

WHAT IS THE DEFINITION OF STANDARDIZED ANIMAL TESTING DATA?
Regulatory toxicology generates most of i ts data from • Standardized methods
• OECD Test Guidelines, ICH Guidance, Regulatory Guidance
• In-bred animals • Charles River CD Rat
The laboratories performing GLP regulatory tests perform many tests on • a huge variety of test articles • but reproducibly following
• standardized protocols • standard operating procedures
With independent Quality Auditing EVERY STEP OF THE WAY 21

Systemic effect levels were curated from EPA ToxRefDB, HESS-DB and COSMOS data bases covering 4379 in vivo studies with 1247 chemicals Systemic effects i n mammalian models are a complex function of chemical dynamics, kinetics and inter and intra-individual variability Systemic effect levels were modelled at the study level by leveraging study covariates such as
• study type, strain, administration route in addition to multiple descriptor sets including
• chemical • biological • kinetic, metabolism, gene expression, oxidative stress & cytotoxicity

The building of a predictive model of in vivo effect levels for repeat-dose systemic toxicity is a complex process due, in part,to varying experimental design and endpoint inclusion This generated an predictive model of systemic effect levels foruse as a safety assessment tool generating predictions for over30,000 chemicals

SEND Ontology (Terminology) is the Key!
Raw data collected electronically e.g. Provantis Toxicology study report generated SEND then “data-mines” the raw data based on Charles River fixed ontology There are 10,242 separate commands in this fixed ontology
This was an expensive programme to develop and is an added price industry is paying to run. Cost could be the insurmountable obstacle!
Is SEND a solution already in place to mine the data?
Note: I do not know if ontology is Charles River specific or specified by FDA

CONCLUSION
There are opportunities and barriers for gaining access to large quantities of standardized animal testing data The benefits and opportunities far outweigh the barriers The barriers are not insurmountable • Businesses & authorities can create the environment to share this data • Protected by the computational models themselves The computational technology is available There are solutions such as SEND which can be used to data-mine Cost and time could be the biggest problem of all
