JaCVAM statement on the Stably Transfected human Androgen Receptor
Transcriptional Activation assay for detection of androgenic agonist andantagonist activity of chemicals using the AR-EcoScreenTM cell line

At a meeting held on 19 February 2019 at the National Institute of Health Sciences (NIHS) inKanagawa, Japan, the Japanese Center for the Validation of Alternative Methods (JaCVAM)
Regulatory Acceptance Board unanimously endorsed the following statement:  Proposal: We consider the Stably Transfected human Androgen Receptor Transcriptional
Activation assay (AR STTA) for detection of androgenic agonist and antagonist
activity of chemicals using the AR-EcoScreen™ cell line to be a useful means ofin vitro screening, which when used in combination with other test methods for theassessment of anticipated hazardous effects is capable of making a significant
contribution to the management of chemical substances.
This statement was prepared following a review of the Organisation for Economic Cooperation and Development (OECD) Test Guideline (TG) 458 “Stably transfected humanandrogen receptor transcriptional activation assay for detection of androgenic agonist andantagonist activity of chemicals” and others to acknowledge that the results of a review andstudy by the JaCVAM Regulatory Acceptance Board have confirmed the usefulness of thisassay.
Based on the above, we propose the AR STTA test method as a useful means for safetyassessment by regulatory agencies.
