The Case Report Tabulation (CRT) is the collection of the annotated case report form (CRF), SAS® datasets, metadata, and source programs that comprise a portion of the NDA package submitted to the FDA. The FDA uses it when reviewing submissions. Review starts with the Define document which contains metadata describing the datasets, variables, and values. It is all tied together using internal and external hyperlinks, bookmarks, and destinations to make it easily navigable 1 . The CRT is essentially a collection of data and documentation for a study. It contains features such as bookmarks and links to allow reviewers to easily navigate the submission. For consistency, there are guidelines from FDA1 and CDISC defining the components though the guidelines are limited in scope. We need to create Define Document ( define.pdf or define.xml ) as a part of CRT. Each dataset is a single SAS transport file and, in general, includes a combination of raw and derived data. Each CRF domain (e.g., d...

The DLP (Data LifeCycle Plan) guides an organization and serves as a blueprint for how to create every type of data across all therapeutic areas and functional specialties. Howard describes the DLP as "an overall document that says here are the things you need to think about." In some DLPs, there might be more than 15 chapters, each controlled by a group of domain experts. Standard operating procedures (SOPs) typically cover process. DLPs, in contrast, are technical specifications about what happens to the data. Both SOPs and DLPs should be subject to similar governance. The DLP creates a framework for discussions that do occur on their own, but it forces them to an earlier stage of the process.

Setting The Record Straight: The Future of ODM, SDTM and CDISC November 05, 2008 By Rebecca Kush, Frank Newby, David Iberson-Hurst, & Amanda J de Montjoie, CDISC When rumors increase, and when there is an abundance of noise and clamor, believe the second report. Alexander Pope, 1688–1744 In recent weeks, there have been a number of rumors about the Clinical Data Interchange Standards Consortium CDISC standards and their continued use by the Food and Drug Administration (FDA). These whispers suggest that the Study Data Tabulation Model (SDTM) standard is being replaced and that the Operational Data Model (ODM) should no longer be used. The rumors have caused confusion at best and fear of standards abandonment at worst. This is a second report—an attempt to clarify what’s happened and how the industry should move forward. CDISC, to state the obvious, is a global standards organization. While the FDA plays a vital role in the drug development industry in the U.S., there are other ...

Define.xml which generally describes what are we submitting to FDA .. like case Report Tabulations ( SAS datasets in XPT format, annotated CRF’s and the variables (metadata)) in a machine readable format….. In simple words it is .....Data and Metadata in Machine-Readable Format. It is considered as the standard process for submitting metadata to FDA and other regulatory bodies….
