CJUG CDASH Team Update

42 members from pharmaceutical, CRO, Lab and academia comprise the CJUG CDASH team. There are currently four sub-teams who get together to discuss the following topics:

  • CRF Library with CDASH conformance
  • Investigate needs and advantage for using CDASH
  • CRF sample with CDASH conformance
  • CDASH v2.0 translation in Japanese following CDISC-COP-007

Recent Outcomes

A team member presented “A supportive document to understand CDASH:  For beginners” during the poster session at the Japan Society of Clinical Trials and Research annual meeting. This reference document is geared toward CDASH beginner implementers who want to understand the ins and outs of CDASH. The document is based on CDASH IG v2.0.
