Abstract submitted for 2018 FDA PhUSE Computational Sciences Symposium
Evaluation of a novel graphical display tool for visualizing and analyzing histopathology data from multiple toxicology studies
FDA PhUSE Computational Sciences Nonclinical Topics Working Group
The ability to aggregate and analyze histopathology data from multiple toxicology studies provides the opportunity to identify trends in target organ toxicities and lesions of concern, and to readily compare results across studies. This functionality is provided by HistoGraphic, a novel graphical display tool which utilizes a “sunburst” format based on a hierarchical concentric ring structure. As proof-of-concept, histopathology data from multiple toxicology studies were obtained from the European Union’s Innovative Medicines Initiative (IMI) eTOX consortium, which constitutes a database of legacy toxicity data from member pharmaceutical companies. HistoGraphic is highly interactive and provides the means for identifying major target organs for each compound, and can be searched by organ or lesion descriptor to rapidly identify findings of interest. HistoGraphic is based on open-source software.
