CDISC Transformer
Development of integrated clinical trials data repository and
CDISC transformer module

● CONTENT
● BACKGROUND
  • Escalating interests of clinical trials and multi-national and multi-institutional clinical trials are increasing.
  • ClinicalTrials.gov trial registry contain and open information on more than 100,000 clinical studies, and even provides summary result data. It aims to improve the clinical resesarch enterprise.
  • However, clinical trial enterprise in domestic is difficult to be advanced due to heterogeneous data formats and controlled vocabularies
  • Based on the international standard Clinical Data Interchange Standards Consortium (CDISC), we develop clinical trial data transforming modules and model to integrate clinical trial information.
