CDISC Controlled Terminology is developed and maintained through a collaboration between the Clinical Data Interchange Standards Consortium (CDISC) and the National Cancer Institute’s Enterprise Vocabulary Services (EVS). The terminology provides the standardized codelists and valid values required for CDISC-compliant datasets used in submissions to regulatory agencies such as the FDA and PMDA.
Controlled Terminology does not define what data to collect, but rather specifies how to represent and submit collected data in electronic datasets. The terminology undergoes extensive content development and public review with broad participation from the research and healthcare community.
Specialized extensions for disease-specific implementations including oncology, cardiovascular, neurology, infectious diseases, rare diseases, and other therapeutic areas.
CDISC Controlled Terminology is updated quarterly with comprehensive release packages. Each release includes:
The most recent update (September 26, 2025) included approximately 662 new QRS terms and 648 new terms across all terminology files.
All CDISC Controlled Terminology products are freely available from the NCI EVS FTP site without licensing restrictions. Users can download individual components in their preferred format or access terminology through the CDISC Library browser interface. Historical versions are maintained in archive subdirectories for version control and reproducibility.
The CDISC community can submit new term requests or suggest changes to existing terminology through the CDISC New Term Request system. The Term Request Tracking system enables community review and comment on all submitted requests, ensuring transparency and broad input in terminology development.
