Data Standards Implementation

Comprehensive Clinical Data Conversion Services to SDTM ADaM Standards

Download Service Flyer

Implementing CDISC Data Standards is our industry’s best practice and is also an FDA requirement for NDAs, BLAs and DMFs. Data standardization enables information system interoperability and provides a consistent general framework for organizing study data in order to create regulatory submissions that are easily interpreted, understood, and navigated by regulatory authorities. Data standardization thus improves the overall quality of data and efficiency of review.

As certified CDISC Registered Solutions Provider we provide professional expertise for the conversion of clinical data to CDISC SDTM ADaM standards. IDDI makes sure your data are ready for submission.

  • All pivotal studies conducted by IDDI are performed in compliance with FDA and CDISC requirements. To reach this goal, IDDI transforms the database structure into an SDTM structure associated with the appropriate documentation. Our EDC is compliant with ODM standards.
  • Our SDTM/ADaM experts have the ability and experience in developing eCRFs to CDASH standards and delivering data in SDTM and ADaM format.
  • SDTM/ADaM datasets are generated using the latest CDISC model in production at the start of the process.
  • IDDI has the experience and capabilities of performing quality control/verification of existing packages to ensure they are ready for submission.
