² Deployed according to integrated testingstrategies using weight-of-evidence
Evolving approaches to testing and assessment
² Ongoing paradigm shift based on expanding knowledge of “adverse outcomepathways” (AOPs)
² Regular updates to regulatory datarequirements needed across productsectors (chemicals, pesticides, drugs, etc.)to keep pace with scientific progress
Concept of “3R best practices”² Strategies to Replace, Reduce or Refine animal use in toxicology, including:
ª Removal of redundant in vivo study requirements, e.g., multiple exposure routes(acute oral/dermal/inhalation) and/or species
ª Uptake of all applicable OECD 3R guideline methods and other scientifically supported alternativetesting (and non-testing) strategies
ª Endp int mbi i ( in viª Endpoint-combining (e.g., in vivomicronucleus as part of 28 daystudy)
ª Adopting more efficientstudy designs (e.g.,extended 1-gen repro)
ª Classification by calculationfor mixtures/formulations

What I am Going to Say…• Definitions of grouping and read-across• Read-across approaches, tools and use• Acceptance of read-across• Biological similarity to increase confidence in • Biological similarity to increase confidence in
read-across• ECHA’s Read-Across Assessment Framework
(RAAF)These are my views and others may wish to
dissociate themselves from them
Key Point 1: Definitions• Category formation, or grouping, identifies
molecules with similar chemical structures• Effects, such as toxicity, may be read across
from a compound with data to fill a gap for a compound with no data

Good Reasons for Using Read-Across• Potential savings in costs, time to market,
animals etc• It is simple and transparent• Allows for mechanistic interpretation and
rational use of toxicity data and information• Several chemicals can be assessed at the same
time, with few data• It has regulatory acceptance (if done correctly)• Provides solutions to problems

• Using metrics of molecular similarity e.g.Tanimoto indices
Key Point 3: Regulatory Use
• Read-across is increasingly being used• It has been applied for many regulatory
purposes e.g. REACH in the EU
Growth in Publications
Web of Science literature search using key words “Read-Across” and “Toxic” performed 28 July 2016
Where Read-Across is UsedCurrent Roles
• Prioritisation, Classification &Labelling and risk assessment
• EU – emphasis on REACH• Interest for cosmetics• Various other roles in USA,
Canada, Japan, Korea, China,Australia etc
• Transitioning from chemicalsimilarity to biologicalsimilarity
Where Read-Across is UsedCurrent Roles

Key Point 4: Acceptance
• Acceptance of a read-across prediction is notguaranteed
• Acceptance relies on thoroughdocumentation, robust justification anddocumentation, robust justification andsupporting evidence
Example of a Category: Terephthalic Acid and Esters
Ball GL et al (2012) Crit Rev Toxicol 42: 28-67.
Can We Fill These Data Gaps?
Probably…. If we have….
• High quality “source” data• Consistency within the data for the category
Ball GL et al (2012) Crit Rev Toxicol 42: 28-67.
• Consistency within the data for the category• We are interpolating• There is a good reason and justification for
data gap filling• We can demonstrate similarity
Well Known, and Worrying, Activity Cliffs Exist WhichDemonstrate Problem of Identifying Similar Compounds
Teratogen Sedative
Whilst Read-Across Predictions have been Accepted,There are a Number of Reasons for Rejection
• Unclear substance identity, not possible toascertain structural similarity
• Lack of sufficient evidence to substantiateassumptions made within read-acrossassumptions made within read acrossjustifications
• Read-across to inappropriate data• Lack of scientific plausibility
Ball N et al (2016) Towards Good Read-Across Practice (GRAP) Guidance. Altex 33: 149-166.
Key Issues with Read-Across
• How can we support a read-across prediction?– i.e. provide further (biological) evidence that
chemicals belong to a group (see Key Point 6)
• When do read-across predictions becomeacceptable to replace an animal test?
Key Point 5: Guidance and Tools
• There is much guidance from regulatoryagencies and in scientific literature
• There are many tools (free and commercial) togroup chemicals or find similar structuresgroup chemicals or find similar structures
• There are databases (free and commercial) toprovide toxicological information
• There are increasing numbers of case studies
Current Guidance•Many sources•Need for consistent approach to reporting and assessing read-across
•Adoption of ECHA’s Read Across Assessment Framework
Several Other InitiativesSeveral Other Initiatives
•Adoption of ECHA s Read-Across Assessment Framework(RAAF) and ensure effectiveness

Key Point 6: Biological Similarity• The future of read-across is more than
chemical similarity (see Key Point 2)• Weight of evidence is required with
supporting information on e.g. mechanism ofaction, toxicokinetics, metabolism etcaction, toxicokinetics, metabolism etc
• Information may be “non-standard” or “non-traditional” e.g. in vitro, high throughput/content screening, or –omics etc.
Application of New Approach Methodologies(NAMs) to Support Read-Across
• Broadly considered to include:– In silico approaches– In chemico and in vitro assays– Information on exposure of chemicals
N t ting tools g. “high th hput eenin ”– New testing tools e.g. “high-throughput screening”and “high-content methods” e.g. genomics,proteomics, metabolomics
– Other methods to improve toxicokinetic ortoxicodynamic knowledge
• Consideration of biological information increasesconfidence
• Proceedings will be published Autumn 2016• Presentations and details of case studies
available from ECHA Website
Key Point 7: RAAF
• RAAF has the potential to bea very important documentto help evaluate read-acrossfor regulatory acceptance
• Demonstrate how NAM canimprove read-acrossargument
The ECHA Read-Across AssessmentFramework (RAAF) Approach
Scientific assessment of a read-across argument according toscenarios defined by 3 key features:
# of substances considered:• Analogue approach – one source and one target• Category approach – multiple source(s) and target(s) (group)
41
Effect (predicted property) caused by:• common substance for source(s) and target(s)• different substances for source(s) and target(s)
For a category, the predicted property:• Follows a regular pattern (trend) across source structures• Does not change across source structures
6 possible read-across scenariosSlide from Andrea-Nicole
Richarz, EC JRC
The RAAF: Assessment Elements andAssessment Options
Set of Assessment Elements (AEs) per scenario• Describing ‘crucial scientific aspects to judge validity and reliability
of read-across for the scenario’• For each AE multiple considerations to be included in justification
42Slide from Andrea-Nicole
Richarz, EC JRC
Assessment Options (AOs):• Reflect the conclusion on adequacy and scientific robustness of the
information provided for the AE• Scores from 5 to 1
• 3 : information provided is acceptable with (3) sufficient, (4) medium, (5) high confidence
• 2 : information provided is (1) not acceptable, (2) not in acceptable in its current form

Conclusions• Read-across provides a means to fill data gaps
when information is available for “similar”chemicals
• Read-across is used widely for regulatorypurposes
• Acceptance of read-across can be complex– Documentation and justification required!– Guidance and case studies on-going
• ECHA’s RAAF may help in developing andassessing read-across arguments and predictions

Data Sharing Provision under K-REACH
A guidance on sharing of registration documents and cost (Feb 2015)
• Joint registrants need to utilize existing data owner the joint registrants and open data source for the data defined in the K-REACH Enforcement rule Article 16 (Joint Submission of Registration Data)
• The risk assessment method (NIER public notice 2014-48) appendix 2 states where to look for the open data source such as risk assessment reports from OECD, UNEP, WHO, data base from ECHA, EPA, and Japan NITE, etc.
• Cost calculation and sharing is between interested parties, not legally determined, but this guidance recommends transparent and fair sharing of registration cost
• This guidance introduce cost sharing method (Sharing data cost by tonnage band or by exact tonnage)
Sharing data cost by tonnageband
Shared cost of an individual firm = (Test costs+administration costs) x
Sharing data cost by exact tonnage
Shared cost of an individual firm = ( ) X ( )
Tonnage of an individual firm
Total tonnage of a person who are going to do registration

When the chemical substance registered according to Article 10 of the Act is used to kill, disturb, or deter all harmful organisms or lives except humans and animals 6. When the accumulated amount of manufacturing and importing new chemical relevant to Article 13, Subparagraph 1 of the Act exceeds 1 ton7. When full text of test data which describes the procedures for producing the data on physiochemical properties and hazard of chemical substance required according to Article 5, Paragraph 1, Subparagraph 1
Data Sharing Provision under K-REACH
• NIER can request additional data for hazard evaluation in case it is necessary• Especially when robust summary is not adequate

Data composition of EU-REACH
In case of EU-REACH data, literature, read-across, and study reports are used simultaneously.And some cases with multiple study reports and supporting documents.
Only 5% of the total registration dossiers submitted is being reviewed and it is ongoing process.
IUCLID data = CSR data (data is consistent)*multiple data in the system
Data composition required in K-REACH
In case of K-REACH, the toxicity and environmental toxicity, NIER is asking for GLP studies with clear test guideline. The highest reliability as possible (1~2 range).
For publication and read-across, there are some uncertainty associated with the evaluation of registration dossier.
Registration dossier evaluation will be done in one year once dossier is submitted.
K-REACH IT System CSR data*One key data is allowed to input into systemtechnically ( expected to be fixed soon)
Conservative approach
Data Sharing: Data Format
COPYRIGHT© 2016 Chemtopia Co., Ltd. ALL RIGHTS RESERVED.
Things considered when doing data gap analysis1. Selection of Keydata2. Reliability (1~2)3. Reference type (Study report / Read-across / Publication)4. GLP, Test guideline5. National Institute of Environmental Research (NIER) exemption criteria6. Data availability as open data (ex. Japan NITE, publication etc.)
Case Study 1: Data Gap Analysis
For data gap analysis, search for open data for existing chemical information
For this search, ECHA, TOXNET, NITE, and SIDS report can be looked into

Chemtopia has submitted the FIRST joint registration dossier to NIER under K-REACH on 07/12/2016.
This submission was accomplished after reducing data productions and purchases by utilizing read-across and existing open data (literatures)
Reduced $600k
Case Study 2: Joint Registration Experience from HBr
Physio-chemical data was submitted by using handbook and literature
Applied exemptions for tests as needed (HBr is corrosive gas)
Read across using PBr3 and other halogen substances etc.with expert' scientific judgement
Data is purchased at the rate of 50% of testing regardless of no. of members
Used other open data along with EU data DNEL of exposure part in CSR is different compared to EU CSR by reflecting additional toxicity data other than EU data

MOE owns some of the PEC substances toxicity data.
Case Study 3: Korea Ministry of Environment’s data for sale
These data is up on the MOE’s website and for sale for data access for the joint registration.
Price of data accessAt the level of SIEF: 30% of the data productionAt the level of individual registrant: 5% of data production (3% for small business)
MOE also published the average Korean GLP test price for reference

Check Points
Identity of substances (SIP)
Purchasing data access
Public consensus on Pricing at 30~50% of Korean GLP lab price
Purchasing at the level of SIEF or at individual registrant
Full study or robust summary (full study report when NIER requests)
Read across / QSAR are associated with uncertainty with NIER (Scientific judgment from expert is essential)
Producing new toxicity data could influence the registration elsewhere (Different result)
Does the substance fall under Substance evaluation-CoRAP(Community rolling action plan), Y2018 registration in EU REACH ?
need to check any ongoing tests or future plan on performing tests?
Reimbursement in case NIER rejects the test studies
