Team Mission and Scope

The CDISC SEND team develops standards that support both the regulatory submission of nonclinical data as well as the operational use and exchange of nonclinical data throughout the industry.

This team is responsible for overall development and maintenance of the production SEND IG (Implementation Guide) versions and their alignment with the SDTM. 

SEND is one of the required standards for data submission to the FDA. Details on the requirements for the FDA are specified in the FDA’s Data Standards Catalog for IND, NDA, ANDA, and certain BLA submissions. For more information, please visit the FDA Guidance on Standardized Data.  


Production releases of the SEND standard:

Standard & VersionSupplemental Materials

SENDIG v3.0, rel. 17June2011 (supports single- and repeat- dose general toxicology and carcinogenicity study data)

Confirmed Data Endpoints for SENDIG v3.0 Data Exchange
(CoDEx 1.0 for SEND v3.0), rel. 16Aug2017

SENDIG v3.1, rel. 07July2016 (supports single- and repeat- dose general toxicology and carcinogenicity study data as well as respiratory and cardiovascular safety pharmacology data)

The above deliverables are available to the public at:

• Nonclinical Research Scientists & Pathologists
• Contract Research Organizations
• Independent Consultants
• Information Technology Tool Developers
• Service Providers


The SEND Team maintains representatives on the CDISC cross-team governance in addition to a long-standing practice of working closely with the CDISC SDS, Controlled Terminology, and XML Technologies teams. With the release of SENDIG-DART v1.1, the SEND team is working closely with the CDISC SHARE effort.

The SEND team partners with the INHAND organization for pathology-related terminology ( SEND also has a strong presence on the FDA/PhUSE Computational Sciences Symposium (CSS) (, including several leadership positions and significant overlap in membership with the Nonclinical Topics working group.

Operating Model

Core Team membership is open to all interested parties with approximately seventy-five active members currently.
Subteams are formed to manage long-term subject areas.
Change Control Board (CCB) assesses and recommends action on changes requested regarding production SEND deliverables.
SEND Leadership Team - sets direction for the team and is responsible to CDISC leadership for the SEND Team; consists of past, current, and future team leaders.
SEND Leadership Team - Extended (SLTX) assists in setting direction for the team, with representation at the CDISC TLC and the CDISC GGG (Global Governance Group).

Work-Streams are for all tasks that are not within the scope of the listed subteams and expected to have a clear start and end (ie, shorter term need). Work-streams are initiated by the CCB or SEND leadership. To develop new leaders on the SEND team, an experienced SLTX member will co-lead or mentor a newer leader for any new Work-Streams. All Subteams and Work-streams are governed by the SLTX and all work is reviewed by the Core Team.
• Cross-team Integrators (or Business Integrators) are individuals who have demonstrated expertise with alignment across all domains and are often needed to review key concepts early in their development. Such individuals will often be needed in specific sessions at F2F weeks. This includes the following individuals:

Jennifer Feldmann, William Houser, Lou Ann Kramer, Louis Norton, Debra Oetzman, Troy Smyrnios, Audrey Walker, Fred Wood, Craig Zwickl


• SEND Core Team meets monthly on Wednesdays for 90 minutes. Active members meet face-to-face at the FDA two times each year.
• SEND subteams and CCB meet biweekly. Work-streams meet as needed.
• FDA/PhUSE CSS Working Group subteams meet regularly via teleconference.
