Where the SDTM provides a standard model for organizing and formatting data for human and animal studies, the SDTMIG is intended to guide the organization, structure, and format of standard clinical trial tabulation datasets. It was developed to support data submitted to a regulatory authority, such as the US Food and Drug Administration (FDA), but is not restricted to use in regulated submissions. SDTM is one of the required standards that sponsors must use as specified in the FDA’s Data Standards Catalog (see section II.C) for NDA, ANDA, and certain BLA submissions effective December 2016. For more information, please visit the Guidance on Standardized Data.

SDTMIG v3.2 Conformance Rules v1.0

Release Date: 27 Jan 2017

The SDTMIG v3.2 details the structure and conventions for compliant SDTM domains. The majority of the SDTMIG v3.2 is published in a data definition table format, which allows the information to be used programmatically. Business and conformance rules (e.g., assumptions and examples), however, are expressed outside of the data definition tables, making them difficult to identify and program.

SDTMIG v3.2 Conformance Rules v1.0 aim to identify all conformance rules and case logic from the SDTM and SDTMIG, classifying and codifying them in a form that supports SDTM quality processes and tool development. 

The Conformance Rules team has created a user guide that provides information on the structure of the rules and conventions for rules content.
