Administrative data

Endpoint:
in vivo mammalian somatic cell study: cytogenicity / erythrocyte micronucleus
Type of information:
experimental study planned
Study period:
subject to ECHA approval
Justification for type of information:
TESTING PROPOSAL ON VERTEBRATE ANIMALS

NON-CONFIDENTIAL NAME OF SUBSTANCE:
- Name of the substance on which testing is proposed to be carried out: BLACK 407

CONSIDERATIONS THAT THE GENERAL ADAPTATION POSSIBILITIES OF ANNEX XI OF THE REACH REGULATION ARE NOT ADEQUATE TO GENERATE THE NECESSARY INFORMATION:

- Available GLP studies: There are no available GLP studies on the substance or on read-across analogues suitable to fill the endpoint.

- Available non-GLP studies: There are no available non-GLP studies on the substance or on read-across analogues suitable to fill the endpoint.

- Historical human data: There is no historical human data on the substance or on read-across analogues suitable to fill the endpoint.

- (Q)SAR: (Q)SAR analysis is not sufficient to fill the endpoint. There are no adaquate models to address this endpoint.

- In vitro methods: Already available, but further in vivo data needed.

OECD Guideline 471 (Bacterial Reverse Mutation Assay)
OECD Guideline 490 (In Vitro Mammalian Cell Gene Mutation Tests Using the Thymidine Kinase Gene)

- Weight of evidence: There is not sufficient data on the substance or read across analogues to be able to establish a weight of evidence argument.

- Grouping and read-across: There is not sufficient data on the substance or read-across analogues to be able to group or propose read-across.

- Substance-tailored exposure driven testing: Not applicable

- Approaches in addition to above: Not applicable

- Other reasons: Not applicable

CONSIDERATIONS THAT THE SPECIFIC ADAPTATION POSSIBILITIES OF ANNEXES VI TO X (AND COLUMN 2 THEREOF) OF THE REACH REGULATION ARE NOT ADEQUATE TO GENERATE THE NECESSARY INFORMATION:

- Test proposal is fully in line with ECHA guidance document (Chapter R.7a: Endpoint specific guidance Version 6.0, July 2017), and can neither be replaced by in vitro testing nor by using other data from other substances.
