2. WHY REACH? Data gaps: 86% of HPVCs have less than base set data
The process takes (too much) time
Burden of proof on public authorities
Administrative burden for new chemicals (low volume) prevents innovation
3. REACH Context Article 1.1: ..purpose of REACH is to ensure a high level of protection on HH and ENV as well as the free circulation of substances on the internal market while enhancing competitiveness and innovation..
Article 25.1:.. Testing on vertebrate animals for the purpose of REACH shall be undertaken only as a last resort necessary to take measures limiting duplication of other tests..
4. Information requirements under REACH General requirements
Information requirements depending on tonnage
NB Cumulative
Flexible with adaptation possibilities
Adequate justification and documentation needed
5. Information requirements under REACH Annex VI of REACH proposal
Annex VII to X:
Minimum information in Technical Dossier depends on volume:
= 1 tonne/y: Annex VII (~20,000 subst)
= 10 tonnes/y: Annex VIII
= 100 tonnes/y: Annex IX
= 1000 tonnes/y: Annex X (2,500 subst)
Possibilities for waiving
6. Intrinsic properties of a chemical Phys-chem properties (e.g. solubility, vapour pressure)
Toxicity properties (e.g. acute toxicity, irritation, mutagenicity, carcinogenicity)
Fate properties (e.g. (bio)degradation, partition coefficients)
Ecotoxicity properties (e.g. toxicity to aquatic or terrestrial organisms)
7. Information requirements under REACH Specific adaptations for individual endpoints
column 2
General adaptations
Annex XI(1): Testing is not scientifically necessary
Annex XI(2): Testing is technically not possible
Annex XI(3): Substance-tailored exposure-driven testing
8. Use of information on intrinsic properties of substances in a regulatory context For Chemical Safety Assessment
For Classification and Labeling of chemicals (C&L)
For the identification of Persistent, Bioaccumulative and Toxic (PBT) and very Persistent very Bioaccumulative (vPvB) substances
9. Key considerations Promotion of non-animal testing
REACH article13.1, Guidance note of Annex VI, Annex VII-X, Annex XI
Alternative information needs to be adequate for C&L and/or RA
Standard information depends on tonnage but can be adapted
10. Annex XI: general rules for adaptation Testing not scientifically necessary
Use of existing data (not GLP/ non standard tests)
Historical Human data
Weight of evidence
(Q)SAR
In vitro methods
Grouping of substances and read-across approach
11. Annex XI: general rules for adaptation Testing is technically not possible
Exposure-driven testing
(only for tests in annex IX and X i.e. = 100 tons/year)
12. Different types of information Exposure information, consider
Testing may be waived when exposure is controlled
Experimental animal test
COM Regulation on adopted test methods (replacing current Annex V to 67/548/EC)
Other experimental methods (Annex XI)
In vitro data
Historical Human data
13. Different types of information (Quantitative) Structure Activity Relationships
Read-across
Category approaches
14. Process for obtaining information Collect and evaluate all available information
Existing test data (in vivo, in vitro) on the substance
Results of QSAR calculations
Establishment of (membership of) chemical category and collection of existing test data and results of QSARs for members of category
Read-across and application of weight-of-evidence approach
Cf. Annex XI(1)
NB! Registrant shall be in legitimate possession of or have permission to use information
15. Process for obtaining information Consider information needs
All information that is relevant and available to the registrant
Annex III options for 1-10 tpa substances
Tonnage-based requirements incl. specific adaptation rules, cf. Annexes VII-X
Substance-tailored exposure-driven testing (general adaptation rules) , cf. Annex XI(3)
Identify information gaps
Final check for existing information
Evaluate whether testing is technically possible, cf. Annex XI(2)
16. Process for obtaining information Generate new data / propose testing strategy: Endpoints in Annexes VII and VIII
Not requiring use of vertebrate animals, conduct test
Requiring use of vertebrate animals, assess whether a suitable in vitro test method is available and, if possible, conduct in vitro test
Requiring use of vertebrate animals but no suitable in vitro test method is available, conduct in vivo test
17. Process for obtaining information Generate new data / propose testing strategy: Endpoints in Annex IX and X
Not requiring use of vertebrate animals, prepare testing proposal
Requiring use of vertebrate animals, assess whether a suitable in vitro test method is available and, if possible, prepare testing proposal for in vitro test
Requiring use of vertebrate animals but no suitable in vitro test method is available, prepare testing proposal for in vivo test
18. Testing proposal Annex VII VIII, no
Registrant should provide data, should consider whether a suitable in vitro test method is available, but can conduct in vivo test
19. Testing proposal Endpoints in Annex IX and X: Yes
Not requiring use of vertebrate animals, ? testing proposal
Requiring use of vertebrate animals, if a suitable in vitro test method is available ? testing proposal for in vitro test
Requiring use of vertebrate animals but no suitable in vitro test method is available
? testing proposal for in vivo test
20. Testing does not appear scientifically necessary, cf. Annex XI(1) Non-testing methods, general provisions
Scientific validation
Results adequate for C&L and/or risk assessment
Adequate and reliable documentation of method
Grouping
21. Testing does not appear scientifically necessary, cf. Annex XI(1) Suitable in vitro test methods
Fulfil pre-validation criteria (e.g. ECVAM criteria)
No dangerous property, confirmatory testing required
Dangerous property + risks not adequately controlled, iterative CSA incl. confirmatory testing as option
Dangerous property + risks adequately controlled, no further testing
22. Testing does not appear scientifically necessary, cf. Annex XI(1) In vitro test methods
Accepted in vitro test methods
Scientifically validated, based on internationally agreed principles
Results are adequate for C&L and/or risk assessment
Adequate and reliable documentation of method
23. Substance-tailored exposure-driven testing, cf. Annex XI(3) General adaptation criteria (not endpoint specific)
Adequate justification is required based on exposure assessment, cf. Annex I(5) COM to adopt criteria on adequate justification within 18 after EiF
Specific conditions of use must be communicated through the supply chain (SDS or article 32)
24. CONCLUSION
Legislative text (Annex XI in particular) + GUIDANCE should limit use of animals and prevent box-ticking
A paradigm shift is needed from extensive animal testing to efficient, focussed animal testing
Impetus to refine current in vivo methods, and further develop non-test and in vitro test methods to be used in a regulatory context.
Further scientific work (2007 onwards) and regulatory implementation is needed.
