The CDISC Submission Data Standards (SDS) Metadata Team has released the final version 1.0 of the Metadata Submission Guidelines (MSG) Package. The package was originally released for public comment from 2010-05-14 to 2010-06-07. During that review period, over 570 comments were received, all of which needed to be resolved before this final package could be released. Included with the package is the Metadata Submission Guidelines (MSG), an appendix to the Study Data Tabulation Model Implementation Guide 3.1.2, which will enable users to become familiar with the SDTM submission components. Included in this posting is a sample electronic submission which includes an annotated CRF, submission datasets compliant with the SDTM-IG 3.1.2, a define.xml file describing the structure and content of the submitted datasets, a stylesheet for visualizing the define.xml in a user-friendly way, and an optional Reviewers’ Guide.

FDA announcements on acceptance of CDISC SDTM 

CBER/CDER Study Data Standards for Regulatory Submissions Position Statement (September 2013)

FDA announced on 6 November 2009 that they will accept SDTMIG v3.1.2 submissions in the Study Data Specifications.


Please note the following taken directly from the Study Data Specifications: Sponsors "should discuss with the review division the datasets that should be provided, the data elements that should be included in each dataset, and the organization of the data within the file. Additionally, not all FDA centers have adopted all aspects of these specifications; sponsors are advised to discuss with the reviewing division data needs prior to preparing data for submission."
