  • QUOTE: SDTM provides a standard for organizing and formatting data to streamline processes in collection, management, analysis and reporting. Implementing SDTM supports data aggregation and warehousing; fosters mining and reuse; facilitates sharing; helps perform due diligence and other important data review activities; and improves the regulatory review and approval process. SDTM is also used in non-clinical data (SEND), medical devices and pharmacogenomics/genetics studies.

    SDTM is one of the required standards for data submission to FDA (U.S.) and PMDA (Japan).

    Details on the requirements for FDA are specified in the FDA’s Data Standards Catalog for NDA, ANDA, and certain BLA submissions. For more information, please visit the FDA Guidance on Standardized Data.

    Details on the requirements for PMDA can be found on the Advanced Review with Electronic Data Promotion Group page.

  • QUOTE:
    • CDISC Foundational Standards are the basis of a complete suite of data standards, enhancing the quality, efficiency and cost effectiveness of clinical research processes from beginning to end. Foundational Standards focus on the core principles for defining data standards and include models, domains and specifications for data representation.
    • Protocol Representation Model (PRM) provides a standard for planning and designing a research protocol with focus on study characteristics such as study design, eligibility criteria, and requirements from the ClinicalTrials.gov, World Health Organization (WHO) registries, and EudraCT registries. PRM assists in automating CRF creation and EHR configuration to support clinical research and data sharing.
    • Standard for Exchange of Nonclinical Data (SEND) is an implementation of the SDTM standard for nonclinical studies. SEND specifies a way to collect and present nonclinical data in a consistent format.
    • Clinical Data Acquisition Standards Harmonization (CDASH) establishes a standard way to collect data in a similar way across studies and sponsors so that data collection formats and structures provide clear traceability of submission data into the Study Data Tabulation Model (SDTM), delivering more transparency to regulators and others who conduct data review.
    • Study Data Tabulation Model (SDTM) provides a standard for organizing and formatting data to streamline processes in collection, management, analysis and reporting.
    • Study Data Tabulation Model Implementation Guide (SDTMIG) is intended to guide the organization, structure, and format of standard clinical trial tabulation datasets.
    • Analysis Data Model (ADaM) defines dataset and metadata standards that support:

  • QUOTE: The CDISC standards span the clinical research process and include standards for the exchange of nonclinical data (SEND), data collection case report forms (CRFs; clinical data acquisition standards harmonization (CDASH)), aggregation and tabulation (study data tabulation model (SDTM)), Biomedical Research Integrated Domain Group (BRIDG) logical model, and operational data model (ODM) for transport (Figure 1). In collaboration with the National Cancer Institute's Enterprise Vocabulary Services (NCI-EVS) program, CDISC has developed a rich controlled terminology that is linked to other common research semantics through the NCI-EVS tools. These standards, presented in data models, implementation guides, and user guides, are globally recognized and heavily used by the biopharmaceutical industry and some academic institutions.

  • QUOTE: CDISC standards (Figure 1) are categorized as Foundational Standards, Semantics, Therapeutic Area (TA) Standards, and Transport Standards. Foundational Standards include Standard for Exchange of Nonclinical Data (SEND) for the collection and tabulation of animal model and other pre-clinical data, Protocol Representation Model (PRM), Analysis Data Model (ADaM) for defining analysis datasets, Clinical Data Acquisition Standards Harmonization (CDASH) that provide a minimal set of data elements common to essentially all studies, the Study Data Tabulation Model (SDTM) for data tabulation, and others.
