How was CTCAE3 loaded? Existing tools and custom script used to convert and load “LexWiki” format into Wiki – CTCAE3 available as a spreadsheet – Mapped to LexGrid model, generated LexGrid XML and loaded into LexGrid database using LexGrid API – Used Protégé LexWiki plugin to get into Protégé OWL and from there into the BiomedGT Wiki – Similar process used to load updated version

Post Work Group Processing Public Comments collected by spreadsheet Comments incorporated into revised spreadsheet Spreadsheet dumped to AccessDB and loaded to LexBIG PDF file populated from the LexBIG file Create OWL file from non-precoordinated version Possible additional changes after steering and governance reviews

Creating OWL file Shallow hierarchy consisting of SOC terms, AE terms and pre-coordinated child terms with grades, e.g. “Grade 3 Febrile Neutropenia” Added – Unique Concept Code – MedDRA code as property – Synonyms (LLTs from MedDRA) – Definitions for AE terms (from NCIt/ or created) – Definitions for Child terms are Grade descriptions from spreadsheet – Basic grade terms with “Is_Grade” relationship to AEs

Grade Terms Concept Code Synonyms - LLTs Preferred Name Is_Grade Relation Def
