Administrative data

extended one-generation reproductive toxicity - basic test design (Cohorts 1A, and 1B without extension)
Type of information:
experimental study planned
Justification for type of information:
A testing proposal is suggested on this endpoint as no available studies (neither GLP or non-GLP) nor historical human data are available to cover the information requirements for this tonnage level. Any potential grouping and read across has been evaluated. The use of (Q)SAR as well as in vitro methods are limited for this type of endpoint. There therefore is no possibility to fill the data gap by any other means than performing the proposed test.
