What is SEND?

  • Standard for Exchange of Nonclinical Data (SEND) is a new electronic formatting requirement for submission of study data contained in certain Investigational New Drug (IND), New Drug Application (NDA), Abbreviated NDA application (ANDA), and Biologic License Applications (BLA) to the US FDA.
  • Nonclinical studies must now implement the Study Data Tabulation Model (SDTM), which is the electronic standard used for clinical regulatory submissions to the FDA.
  • SEND, SDTM, and associated standards are developed by CDISC (Clinical Data Interchange Standards Consortium), a non-profit standards development organization consisting of representatives from pharma, biotech, CROs, vendors, consultants, and the FDA.
  • On December 17, 2014, FDA published a final guidance on the use of standardized electronic formats (i.e., SEND and SDTM) for applicable nonclinical and clinical submissions. These electronic standards have become mandatory for all studies starting December 2016.

Importance of SEND

  • SEND is being used by the FDA to analyze data in study submissions
  • Rapid access to large amount of data, faster FDA review and therefore faster time to market
  • Uses controlled terminologies
  • Standardized formats
  • Enhanced data review
  • Eliminates data entry by agency
  • Enables data warehousing, analysis and visualization
  • Noncompliance can result in a refusal to file from the FDA and submission delays.

Timeline for Implementation of SEND by FDA for all Sponsors, CRO etc.

The final FDA guidance on standardized electronic formats, issued on December 17, 2014, has become binding (i.e., SEND and SDTM will be required) as follows:

  • For applicable NDAs, ANDAs, and BLAs: Studies starting after December 17, 2016
  • For applicable INDs: Studies starting after December 17, 2017
