Example CRF Completion Instructions

  • Record all adverse events (AEs) except [list of protocol-defined exceptions] on the AE CRF after informed consent is obtained.
  • All serious adverse events (SAEs), regardless of relationship to study drug, must be reported via telephone or fax within 24 hours of discovery.
  • Safety information (e.g., AE, SAE) identified for all subjects must be recorded on source documents from the time informed consent is obtained.

This SDTM example illustrates data from an AE CRF that collected AE terms as free text. AEs were coded using MedDRA, and the sponsor’s procedures include the possibility of modifying the reported term to aid in coding. The CRF was structured so that seriousness category variables (e.g., AESDTH, AESHOSP) were checked only when AESER is answered “Y.” In this study, the study reference period started at the start of study treatment. Three AEs were reported for this subject.
